1. Call to Order

Mr. Brambley called the meeting to order at 8:01 a.m. and noted that a quorum was present.

2. Welcome/Introductions

Members and guests introduced themselves.

2.1 Introduction to the Publications Committee

Mr. Owen gave a brief PowerPoint presentation (Attachment A) on the committee, its structure, and operations.

Members discussed committee operations.

Mr. Gebke asked how members can stay abreast of development in various publication areas. Mr. Comstock answered that the status of all publications is a complex picture; tracking documents give as good an overview as is available in one place.


3

Ms. Huang asked how to suggest topics for ASHRAE Journal. Mr. Comstock answered that the best way is to send to the Journal editor. He added that members’ expertise is needed regarding both the technology and the best publication platform for that technical information from a user’s perspective.

Mr. Fly said that committee members can encourage TCs and other content development groups to speed content to the market.

2.2 Onboarding practice improvement

Members discussed ways to improve how new members are integrated into committee activities.

Mr. Dwyer suggested that the committee’s Manual of Procedures (MOP) and Reference Manual should be revised to reflect the committee’s practices. He added that the committee also needs to consider how to ensure active involvement of international members.

Ms. Huang said that a document with basic guidelines or a “roadmap” of expectations would be helpful; Mr. Beaty suggested an “at-a-glance one-pager” for that purpose.

3. Minutes Approval, Annual Conference, January 2015

It was moved and seconded

(1) to approve the minutes of the January 2015 meeting.

Members discussed the level of detail that the minutes should contain regarding committee discussions.

Mr. Owen said his practice has been to pick key points from discussion to record in the minutes; however, this is subjective, and members’ feedback is important for ensuring accuracy. This is why, he added, the minutes are sent to all members for review, usually within 15 to 30 days after the meeting.

Regarding audio recordings of meetings, Mr. Gulledge noted that ASHRAE policy prohibits such recordings, except for technical program seminars.

Mr. Bansal said that the practice in Research Administration Committee (RAC) has been for members who want their comments to be noted in the minutes (or to not be noted in the minutes) to make an explicit request for that.

Mr. Beaty mentioned a study showing that meeting participants forget 80% of events within 24 hours, but if notes are rewritten within those 24 hours, memory retention increases to 80%, for a 4:1 return on investment (ROI) in meeting time.

MOTION (1) PASSED, voice vote.

4. Agenda Review/Updates

The following addition was made to the agenda:

12.1 UFAD Operations Guide proposal (TC 5.3)

5. Remarks by BOD ExO and CO

Mr. Fly, Board of Directors Ex-Officio member (BOD ExO), thanked committee members for their attendance and efforts during the year. He said that the committee’s oversight and stewardship of publications is important, because such dissemination of technical information is key to reaching ASHRAE’s goals.

Mr. Boyce, chair of Publishing and Education Council (PEC) and Coordinating Officer (CO) for the committee, thanked the committee for their work. He said that publications is one of the economic engines for Society, providing needed income to support many activities. He also briefed the committee on the Building Performance


4

Alliance, a Presidential Ad Hoc committee formed two years ago to create a commissioning “roadmap,” to give building operators tools for more effective operations.

6. Action Items (from January 2015 Winter Conference)

7. Special Publications

7.1 Special Publications Editor’s Report

Mr. Owen highlighted items published since January 2015 (Attachment B), reviewed the Special Publications Projects spreadsheet (Attachment C), and reported the status of publications needing review (Attachment D).

Regarding Attachment C, Mr. Dwyer asked about the status of the Design Guide for Sustainable Refrigeration. Mr. Owen reported that there had been a delay or question about funding participation by the United Nations Environment Programme (UNEP). Mr. Owen said he will check with the project committee liaison regarding the status (ACTION ITEM #1).

Mr. Mills said that the new Cold-Climate Buildings Design Guide is expected to be published in time for the Cold Climate Conference in China this October. The book will be formally launched at the 2016 ASHRAE Winter Conference in Orlando. The book’s cognizant development group, the Cold Climate Design Guide


5

multidisciplinary task group (CCDG.MTG) has targeted January 2018 to publish the next revision of the book, in conjunction with the 2018 ASHRAE Winter Conference in Chicago.

Mr. Mills reported that work on the Hot Climate Design Guide (under HCDG.MTG) is under way but running behind schedule. They are working with members from Region-at-Large, and participants are more widely scattered around the world, making coordination more of a challenge. Mr. Dwyer suggested that the MTG look at CIBSE’s publication on the topic, to evaluate the possibility of cooperation on the book. Mr. Mills said he would talk to CIBSE (ACTION ITEM #2).

Ms. Huang requested copies of the Energy Efficiency Guides. Mr. Owen will respond (ACTION ITEM #3).

Mr. Brambley requested that members who can help with TC contacts look at the list and volunteer:

• Mr. Mills: TC 1.7 (ACTION ITEM #4)• Mr. Beaty: TC 9.9 (ACTION ITEM #5)• Ms. Huang: TC 6.9 (ACTION ITEM #6)• Mr. Gebke: TC 5.2 (ACTION ITEM #7)

Mr. Dwyer and Mr. Fly suggested that the new Thermal Comfort Tool (TC 2.1) could be investigated for conversion to an app (mindful that this new tool is based on the CBE Thermal Comfort Tool.)

Mr. Beaty said that he would prefer a transactions log to an Excel spreadsheet. Mr. Fly said he would like to include sales history in this log.

8. Subcommittee Reports

8.1 Apps Ad Hoc

Mr. Dwyer presented a report (Attachment E) describing results of surveys of ASHRAE TCs and YEA members regarding needs for apps and preferences for platforms. He added that, as chair, he will encourage more app development, perhaps with a competition for the best concept or developed app.

8.2 Curricula Ad Hoc

Ms. Todorovic presented a report (Attachment F) describing the results of a survey of academics regarding use of ASHRAE publications in university curricula.

Regarding the comment on the quality of ASHRAE’s review processes, Mr. Dwyer asked how many persons were surveyed. Ms. Todorovic answered that only a few individuals were interviewed. Mr. Bansal commented that the review process for Science and Technology for the Built Environment (STBE) is very rigorous. Ms. Huang said that some trust issues may arise from authors misunderstanding the review process.

Mr. Brambley asked Ms. Todorovic and the ad hoc to provide three to five bullet points for recommendations to address the issues identified in the report (ACTION ITEM #8). Ms. Todorovic said that this report reflected only an “initial analysis,” and additional work is needed to formulate recommended solutions.

Ms. Huang noted the comments on prices for older publications, and asked if ASHRAE sells old Handbook editions. Mr. Owen answered that excess inventory is typically discarded because those editions are superseded by the new editions, which are the only versions with the official approval of the cognizant TCs. Print runs are planned to exhaust the hard copy inventory just before the new edition is published. Older editions are typically widely available for purchase from individuals at a broad range of prices via online outlets.

8.3 International

Mr. Mitroga presented a report (Attachment G) on international needs, how ASHRAE could respond, how ASHRAE is already meeting the need, other relevant ASHRAE activities, and recommendations for follow up. He commented that, to continue growing, ASHRAE needs to analyze the cost/benefits of translations, adding that the translated versions do not necessarily need to be printed; downloads are good for this purpose.


6

Mr. Fly said discussions are under way (including global consulting firm MCI) regarding the approach to ASHRAE’s strategic globalization effort. A regional pilot project will likely result. Mr. Dwyer said that preliminary work has led to MCI focusing on Europe and the Middle East in the next phase.

Mr. Beaty suggested that ASHRAE focus on universality in its publications--more graphics and simpler text, for easier translation.

8.4 Operation Ad Hoc

Mr. Ferguson gave a PowerPoint presentation (Attachment H) on producing publications for optimal building performance. He added that consideration of buildings’ resiliency should also be addressed.

Mr. Beaty suggested that we ask what can be done easily. If so, move forward; if not, reduce the scope a little.

Mr. Dwyer commented that similar roadmaps could be worked out for other publications/topics.

8.5 Residential

Mr. Brambley reported that not much progress had been made in this area, adding that he takes responsibility for the lack of clear guidance. Mr. Gebke asked where ASHRAE intends to go in this market; it is difficult to proceed until that information is known. Mr. Brambley said that the BOD will be discussing this at the conference, with clearer direction anticipated to be forthcoming.

Mr. Beaty said that the residential topic could be approached from the standpoint of zoning, high-level calculations, and/or net zero design. Mr. Ferguson suggested that this could be an app.

8.6 ASHRAE Journal/Insights Review

8.6.1 ASHRAE Journal Editor’s Report

Mr. Scott introduced himself as the new editor of ASHRAE Journal and answered members’ questions about content themes. He said the editorial and advertising teams are working on the 2016 Editorial Calendar, which will be finalized for the July sales meeting. He invited members to send him ideas for Journal articles.

9. Liaison Reports

9.1 Certification Committee

Mr. Brambley reported that he attended the Certification Committee’s meeting and that there was no discussion of needs for publications to support certification preparation. He recommended that future chairs contact the chair of Certification to get on the agenda.

9.2 Professional Development Committee (PDC)

Mr. Brambley requested a volunteer to go to the PDC meeting. Ms. Huang volunteered. Mr. Brambley suggested that she contact the PDC chair beforehand to explain the role Publications could play in supporting PDC work.

9.3 Research Administration Committee (RAC)

Ms. Todorovic reported that she will attend the RAC meeting and contact the RAC chair beforehand.

10. MBOs

10.1 2014-2015 MBOs

Mr. Brambley reviewed the status of MBOs for 2014-2015 (Attachment I). (Also see 8. Subcommittee Reports.)


7

10.2 2015-2016 MBOs

Commenting on 2015-2016 objectives, Mr. Dwyer said he wants them to be deliverable during the year, and that the committee needs to avoid spreading itself too thinly. The objectives, which will be forthcoming following the conference, should be realistic, building on the foundation previously laid.

11. Strategic Planning

11.1 Continuous strategic planning recommendations

(No report.)

12. Old Business

12.1 UFAD Operations Guide proposal (TC 5.3)

Mr. Gebke moved and Ms. Huang seconded

(2) to approve TC 5.3’s proposal for a new underfloor air distribution systems operations guide as described in Attachment J.

MOTION (2) PASSED, 6-0-1, chair not voting.

Mr. Dwyer abstained because he had not reviewed the proposal.

13. New Business

Mr. Brambley reminded members of the offer from the ASHRAE President to send a thank-you letter to employers of committee, council, and board members. To respond, members should follow the link in a letter sent to all members in early June.

Mr. Brambley thanked the committee members for their contributions and urged members to support Mr. Dwyer as incoming chair.

Mr. Dwyer thanked Mr. Brambley for his service as chair.

Mr. Dwyer said he plans to hold a virtual meeting around September to keep everyone up to date.

14. Adjournment

Mr. Brambley adjourned the meeting at 11:58 a.m.

PUBLICATIONS COMMITTEE 2014 TO 2015 Att. E AD HOC GROUP ASHRAE APPS (2015) PUBLICATION COMMITTEE WORKING GROUP June 2015 Membership Chair - Tim Dwyer - [email protected] Don Beaty - [email protected] Jack Glass - [email protected] Objectives To determine the current and near future state for 'apps' and software relevant to ASHRAE activity to inform the planning of appropriate App development Timeline This working group committee was established initially for 6 months duration from January 2015 to June 2015. It may be continued if required at the behest of Chair of Publications. The Ad-hoc has held two conference calls and several email discussions Discussion The committee considered that society's (not just ASHRAE) shift in the use of tech rather than physical resources, with notable movement in very recent times so that most ASHRAE members are likely to now have 'smart'/mobile devices and certainly the Gen Y (and many Gen X) sport electronic gizmos that is a complete shift in profile from just a few years ago The ad-hoc determined that it was important to understand…

- the current position of apps/software in ASHRAE and in other relevant groups/associations;

- what TCs (and other tech groups) see that they could usefully exploit or simply need in app development;

- what the Gen Y, group represented by YEA, see as the future need/desire in mobile 'publications'/apps/software for ASHRAE related activities.

Workplan

- Establish a schedule of ASHRAE current software/apps offerings - Canvas YEA for their opinion - Canvas the technical groups within ASHRAE to see what their desires/preferences are

both in the form and delivery mechanism of the apps/software and the tech areas of specific potential application

- Establish a schedule of other (external to ASHRAE) groups and society software/apps offerings that may help inform the path of ASHRAE development

- Report back to Publications Committee at June 2015 Atlanta meeting Outputs 1.

HPB and ASHRAE Journal articles and case studies. Tools for on-the-spot, ballpark specification of basic design or basis construction concepts. Quick calculation of ventilation rates for a particular space. Lookup of particular Standards sections, table data. System effect calculation app to be used in the field. Valve sizing Pumps sizing Flow, Pipe Sizing calculators Pipe sizing Delta T evaluating Calculate AFUE (ASHRAE 103) Must help in the field where access to resources is limited. Best if not required to be online since internet access is not always available Standards Wiki Handbook Design Guide Operation and Maintenance of HVAC systems. IAQ / IEQ, PM2.5, particulate cleanliness in room - sub micron. heating, cooling, airflow required expansion tanks Electronic ductulator

duct fitting database Ask the expert..direct inquiry to TC 5.2 duct design or ""other"" relevant TC Stack effect infiltration Environmental gradients with height (ie temp, humidity, air quality, wind) Pressure break calculator Delivery of standards on tablets. A BACnet property explorer would be useful. The Noise & Vibration chapter in the Handbook is ripe for spreadsheet links, audio files, etc. I think it would be great if these could just launch through a weblink, but not be sold as stand-alone applications, because: 1) too much difficulty adapting to all devices, 2) need for random updates. More specific comments and ideas Check out CIBSE's app. It's very easy to use, updated regularly and provides access to the broad range of products, case studies, and technical data. It runs circles around any of the ASHRAE apps available to date. App would have three basic sections. One would be a rate calculation - user picks a space type, enters floor area and occupancy, and then Table 6.2.2.2 would be displayed to select Ez, and the resulting Voz would be displayed. Section 2 would show the Table of Contents and links would display selected sections of the standard. Section 3 would show a list of tables and links would display the selected table. When a site modification is required to the ductwork design, often the contractor/installer do not fully understand the adverse effect a field modification has on a systems performance. This application could compare the design system effect versus the modified system effect. An app for calculating pipe sizes An app for evaluating the effects of Delta T on pipe and system operation. Ductilator Acoustic meter for NC measurements. Distance measurement tool An app that contains the Section 5 tables from Standard 180. That would allow a user to input the component or portion of a HVAC system and that would call up a list of inspection points for that component. The app could even have the ability to input the identity of that component (AHU X) and the performance objectives related to that component (X CFM; X delta T...). In addition, the app could allow the user to record results of that inspection task (pass, recheck on x date, immediate repair required...). basic equations. plug in known values and app solve for the unknown values. Could work for duct work, cfm, size, velocity, delta T, energy transferred pipe in similar fashion. Electronic ductulator Duct fitting database

Ask the expert..direct inquiry to TC 5.2 duct design or ""other"" relevant T Delivery of standards on tablets: An indexed and easily searchable version of 135 and 135.1 for the iPad and Android Tablets. The PDF files for 135 and 135.1 is almost unusable as reference guides. Some years ago, ASHRAE provided the BACnet CD which was fully indexed and searchable and easily navigated via links to various sections. While Windows help files are completely out of vogue these days, and are only minimally supported by Windows, a version of the BACnet standards for tablets (don’t forget the Kindle!) would be a great tool. There are a ton of Excel spreadsheets that could be used for a start. 3. Review of Apps Produced by Other HVAC&R Organisations A list of global HVAC&R organisations was produced and each one was searched fo evidence of Apps. The results (below) show surprisingly few.

Transaction/Journal and Potential new Journals or Special Issues (IEEE Story)

There was a long and strong perception among major US universities, Depts. of Mechanical Engineering, that ASHRAE lacks in providing strong (academically relevant, rigorous peer review process,…) publication venue(s).

“Prof. Ray Cohen understood the need for a publication by ASHRAE and for ASHRAE related research in thermal sciences, especially for people from academia where papers published by ASHRAE (Transactions) were and are seen as a second level (at best) and did start HVAC&R Research Journal which became the SCI journal with raising Impact Factor.

At the beginning of the year the “HVAC&R Research Journal” became “Science and Technology for the Built Environment” filling the increased interests and needs of people that are in the business of energy for buildings for a good journal. Its Impact Factor is probably even sooner going up.

ASHRAE’s shift towards buildings is very logical and strong, but it should not forget refrigeration machines, equipment, cycles, and similar topics. Nevertheless there is a notion that enhancement of ASHRAE’s activities in energy for buildings should be w/o choking other areas. Generally, it is an opinion that ASHRAE should continue to have venues with quick turnaround for publication and presentations for new results and people from industry.

Nevertheless, venues (conference presentations, journals) with strong peer review focused on machines, refrigerants, flow and heat transfer, … are needed to resurrect trust in ASHRAE by academics in these areas or reputation will continue to dwindle.

A FEW ON STUDENTS

HVAC professors do encourage students to join ASHRAE and purchase the Fundamentals volume -- the low student membership fee and reduced volume price make this attractive (this is worldwide trend – RAL Chapters Student Branches grow - 6 Student Branches for example in Danube). Setting (low) student prices on various publications would be helpful (for example current load calculation manual and various designer's guides), and also Standards 55, 62.1, and 90.1, also psychrometric chart comp. If free "desk copies" are not provided to instructors, extend this student pricing to the instructors as well. “I'm not sure I'd recommend it for ASHRAE, but some other organizations have dirt-cheap student prices on the past versions of publications as a way to clear inventory.” Written Marija S.

ASHRAE PUBLICATIONS—INTERNATIONAL CONTENT Att. G

INTERNATIONAL SUBCOMMITTEE

Sunday 28th June 2015

1 What does international membership want/need?

ASHRAE has been responding to a growing demand from international members across the world for technology transfer. There is a clear demand for ASHRAE technology. For many that means what North America uses for everyday engineering.

Developing countries are particularly in need of guidance as they start to build out from a standing start (compared to developed countries).

For others it means joining an organisation that has a proven track record in delivering useful data to assist with design and construction of engineering systems in buildings in the belief that ASHRAE can be a vehicle for developing information (publications) which can be used across the world.

There is no one else doing this at the moment – and probably no other organisation capable of doing this.

ASHRAE are now recognised as the leading authority on HVAC and R technology and this supports other areas such as sustainability , energy in buildings, environmental design and related topics. At the moment ASHRAE publications have a distinct North American flavour. However much of the content is relevant at a technical level anywhere in the world.

2 How does ASHRAE respond to this demand?

This has already started by sharing—to ASHRAE members worldwide—what are ASHRAE’s current series of technical documents—possibly written for North America use, but not necessarily, to increasingly documents written with other climates and countries in mind.

3 What does ASHRAE need to do next?

This growing interest in having ASHRAE technology across the world has resulted in ASHRAE starting to ask what is this demand and how big is it or could it be, and more to the point, what is actually needed.

4 ASHRAE technology already satisfies some of this demand.

One point which favours ASHRAE is the wide range of climate regions in the Publicationss, guides, standards and special pubs. A new climate region Zero is being introduced for very hot and dry middle east countries, using Riyadh.

It appears that climate regions can be used to cover most places around the world. This is very helpful to countries that have little climate data available.

ASHRAE weather data files are already used in many simulation programmes such as IES.



ASHRAE also covers basic science and engineering calculations extremely well and better than most others, for example load calcs and psychometrics etc etc. This is used across the world by all engineers.

5 What else is needed and where should ASHRAE prioritise?

There are moves within ASHRAE to clarify these matters….

RAL – Region at Large

Currently organising a survey of all international members in RAL. This will include questions about use of ASHRAE Publications. RAL meets Monday at 2.15pm and I will attend to find out what results they have from this work.

Issues such as

• Do you use publications • Which ones • Do you need any others • Would translations be useful

PLC – Planning Committee

In the process of undertaking research and surveys into the potential for growing international membership. Questions will include use of ASHRAE publications, what publications are needed, how much they use, or could use ASHRAE publications.

This initiative follows the new strategic plan.

This is a major initiative and is being directed by the Board.

Developing Economies Presidential Ad Hoc Committee

ASHRAE is creating a new program devoted to the Developing Economies (DE) aimed at contributing to the clean and sustainable holistic development of the integrated buildings construction/HVAC industry, preserving natural resources including water, richness of the diversity of the territories, protecting the environment and suppressing pollution, and helping to raise the level of health and well-being, worldwide. The Publicationss can help achieve these objectives.

AASA – ASHRAE Associate Society Alliance

The AASA are keen to see ASHRAE lead initiatives world wide. At the AASA meeting on 26 January 2015, ASHRAE and UNEP agreed to join forces to help develop technical guidance for phase out of HCFCs and to help the UNEP Ozone programme. This will be carried out in conjunction with AASA member countries.



Cold Climate Design Guide

Working with international members, ASHRAE have produced a new design guide for cold climates. This will be available at Atlanta and also at the next Cold Climate conference in China in October 2015.

A similar initiative with a new Hot-Climate Design guide is under way and will involve ASHRAE chapters across the Middle East and elsewhere.

6 Other methods and initiatives

ASHRAE are now running conferences and courses across the world in selected places. These are proving successful at generating data for publications which can be used elsewhere.

7 Conclusions

Publications Committee needs to engage with and be aware of the research and other initiatives mentioned above. Publications should consider ways of assisting authors to produce suitable material for inclusion in the Publications to help this process develop effectively.

Publications should monitor and be willing to reference any other new publications which are produced as part of the above initiatives. The Publications should always be the central source of ASHRAE material and at the very least direct members to other ASHRAE Publications wherever relevant.

1.3.1 Life Cycle Costs [Add Text Here]

1.3.2 Energy optimization & Performance A protocol used to assess overall performance of the UFAD system should contain the following three primary elements:

1. ENERGY STAR rating system. This relatively simple procedure uses one year’s worth of monthly data for electricity, gas, and water consumption from utility meter records to provide a comparative assessment of the building’s energy performance. These data are entered into the EPA Portfolio Manager calculation tool to obtain the ENERGY STAR rating (on a scale of 1 to 100) for the building. This process compares the building’s energy performance with a large database of similar buildings nationwide (EPA 2012).

2. Temperature measurements. It is difficult to fully evaluate UFAD performance without measuring stratification and diffuser discharge temperatures. During a 3–4 day site visit, using a mobile measurement system to collect this data can result in a wealth of insights in how to proceed with adjustments (CBE 2010a).

3. Occupant satisfaction survey. This survey, administered via the Internet over a 1–2 week period, provides an assessment by the occupants of the quality of their indoor environment. The survey addresses all major categories of indoor environmental quality, including thermal comfort, air quality, lighting, acoustics, cleanliness and maintenance, office layout, and office furnishings, as well as satisfaction with floor diffusers. The survey results can be compared to a large benchmark database maintained to assess relative performance (CBE 2010b).

ASHRAE’s Performance Measurement Protocols for Commercial Buildings embodies all of these features (and more) and is a good way to evaluate performance (ASHRAE/USGBC/CIBSE 2009).

Chapter 8 discusses aspects of energy performance that can be helpful in guiding an assessment of energy performance.

2.5 Manual, CV and VAV Diffusers

Constant Volume (CV) Constant-volume systems are best used for spaces or zones that have fairly consistent and constant load profiles during occupied times. For example, spaces with high occupant densities and/or consistent internal loads, such as a call center, may be an application suitable for CV systems with manual diffusers. The basis of CV is that constant static pressure in the underfloor plenum is maintained to ensure CV airflow from each diffuser, as long as the diffusers are the same model and setting. Plenum pressure is maintained by adjusting fan speed at the air handler. Occupants can make minor changes to local comfort conditions by manually adjusting an AV diffuser, but such adjustments are viewed as setup not operating adjustments. As long as load variations in the zone due to diversity and other occupancy changes are small, and the net impact on plenum pressure by occupant diffuser adjustments is minimal, this strategy results in nearly constant-air-volume operation and can maintain acceptably comfortable space conditions. In this configuration, one strategy for controlling space temperature is to monitor temperature and adjust supply plenum pressure or temperature to match the load profile of the space.



6 of 29| P a g e

However, even with proper design that promotes stratification at peak conditions, CV operation can result in a changing environment in the occupied region as load changes. In CV UFAD control, constant supply air temperature with decreasing load causes the space temperature profile to shift toward cooler temperatures and become less stratified. In this case, the average occupied zone temperature tends to be a few degrees cooler than the peak load thermostat temperature. Thus, either supply air temperature reset or supply air pressure reset is recommended. Refer to Sections 12.5.6 and 12.5.7.

Many projects use constant-air-volume systems for large interior zones where the perimeter zones are served by supply air passing through the plenum of the interior zone. If these interior systems were conservatively sized, as compared to actual loads, and zone airflow is not properly adjusted during system balancing, then the zone will be overaired. As discussed in Chapter 4, air leakage from pressurized plenums, plus the additional heat loss through the floor surface, can provide a substantial portion of the required cooling under part-load conditions. If part-load conditions or overairing in the interior leads to a significant increase in supply air temperature, this may compromise the system’s ability to accommodate peak perimeter cooling loads if they occur simultaneously. In constant-air-volume systems, interior zone airflows should be well matched to actual loads; active and robust control of supply air temperature or supply air pressure reset should be employed without starving the perimeter or other zones under a different load profile at the time.

Variable Air Volume (VAV) VAV systems are typically used for both perimeter and interior zones that have loads that fluctuate throughout the occupied hours. Usually, VAV diffusers with modulating dampers controlled by a space or zone thermostat are used for these applications. However; some systems have successfully used a combination of both CV and VAV diffusers served by a common plenum.

Diffusers are modulated open or closed to satisfy the current load based on feedback from the thermostat. As diffusers modulate open and closed, the pressure in the supply air plenum will fluctuate unless secondary control is employed to maintain a constant supply air plenum pressure. The method of pressure control used is different based on the method of air delivery to the space.

2.5.1 Baskets [Add Text Here]

2.6 Fan powered devices Underfloor fan terminal units are typically used in perimeter zones and other zones where large and rapid changes in cooling and/or heating load requirements occur. The section that follows describes these units in physical terms and broadly discusses how they may be controlled. Chapters 5 and 12 further discuss the application of UFAD fan terminals for perimeter and conference area applications.



7 of 29| P a g e

Figure 6.7 shows an example of one such terminal unit featuring two

variable-speed fans (for added capacity) and a hot-water reheat coil. Despite the large profile of this unit, Figure 6.8 demonstrates how its installation, as well as that of a standard single-fan terminal unit, is compatible with the 2×2 ft (0.6×0.6 m) grid of raised-floor support pedestals

in an underfloor plenum. The height of fan terminals used for UFAD

applications must also be considered to ensure adequate clearance below the raised floor panels. Most UFAD fan terminals require a plenum cavity 12 in. (30 cm) or greater. UFAD fan terminal units can be configured to provide a number of operational sequences, including constant or variable airflow delivery and may be fitted with heating and/or cooling coils. Note that locating cooling coils under the floor raises significant issues with draining of condensate pans. Where possible, any cooling coils within the UFAD plenum should use chilled water whose supply temperature is maintained above the plenum supply air dew point, and should have a sensor that shuts off the water supply if the water temperature approaches the dew point in the plenum.

Figure 6.7�Underfloor Fan Terminal with Two Variable-Speed Fans and HWater Reheat [Source: Greenheck (2002)]



8 of 29| P a g e

Care should be exercised to locate fan terminals used in UFAD applications

such that they can be accessed for maintenance. These terminals should have top access doors and panels and should be located such that space furniture and partitions do not prohibit their access. If filters are provided with these terminals, they should only be used during construction and should be removed after the floor slab has been cleaned and before the raised access floor tiles are installed.

Figure 6.9 shows a schematic diagram of a typical fan-powered terminal serving a perimeter zone. Plenum air is drawn in by the fan and then ducted to the supply outlets assigned to that zone. The supply air delivery may be CV (either continuous or intermittently provided) or VAV (the fan speed controlled in accordance with the zone thermal demands). An integral electric or hot-water reheat coil affords the terminal the capacity to also provide space heating when required. These terminals could also operate only when space heating is required, in which case they would reheat air from the plenum.

Figure 6.10 illustrates a CV mixing-type fan terminal for UFAD applications. The fan is controlled to provide a constant volume of supply air to the space. During periods of maximum cooling demand, this delivery is 100% plenum air. As the cooling demand diminishes, dampers adjust the induced (room and primary) air mixture accordingly. Upon demand for heating, the mixture is adjusted for a minimal amount of plenum air, and the terminal’s electric or hot-water heating coil is energized.

Figure 6.9�Typical Fan-Powered Terminal Serving Perimeter Zone



9 of 29| P a g e

Figure 6.11 depicts a unique fan-powered terminal configuration serving a

perimeter zone. The terminal unit with a hot-water or electric heating coil is used in combination with two or more VAV diffusers (Figure 6.2) to provide both cooling and heating operation. During cooling mode, the fan is off, and all diffusers operate in normal VAV mode to deliver the desired amount of cool plenum air. During heating operation, the fan terminal is activated, pulling return air from the room through diffusers on the inlet side of the fan and supplying air to the room through the diffusers on the supply side. Figure 6.11 shows the diffuser dampers adjusted in full heating position, although an adjustable stop for the damper can be installed to provide minimum ventilation air from the plenum. Under thermostatic control, room air provides the first stage of heating followed by activation and

modulation of the heating coil. This perimeter solution requires no underfloor partitions.

2.6.1 Power Concerns

2.7 Accessing Underfloor Area

Floor Tile Removal An overarching installation consideration that affects both access and flexibility is the surfacing material placed over the floor panels. Specifically, the alignment and sizes of carpet tiles can significantly affect the ease of floor panel removal. In some cases, carpet tile seams are staggered over the floor panel joints to help seal the joints and reduce plenum leakage into the conditioned room. This overlapping requires the disturbing of at least four carpet tiles on the eight floor panels surrounding the panel to be removed.

Space unavailable during remodeling 30%–70%

Absenteeism 5%–10%

Employee disruption and dead time during remodel 50%–80%

Source: Journal of the International Facilities Management Association

Carpet tile staggering is primarily the result of concerns over

uncontrolled plenum leakage to the conditioned space through the floor panel joints. It is the consensus of the ASHRAE Technical Resource Group on Underfloor Air Design (TRG7.UFAD) that floor tile leakage to the conditioned space is not an issue, provided that leakage is not excessive—i.e., to the point where space conditions cannot be controlled. Therefore, the O&M community should require the A/E firm to select a floor panel system with low dimensional tolerances and installers that are experienced and demonstrate good workmanship. This will allow the use of one-to-one matched carpet tiles. Similarly, carpet tiles with a dimensional tolerance near that of the floor panels should be specified. Finally, it should be specified that carpet tiles be installed in a manner that minimizes cumulative error in seam matching—i.e., carpet installation should start at the center of each area and work outward, as opposed to starting at one wall.

15.1.2 System and Equipment Accessibility The raised access floor allows for easy accessibility to UFAD equipment and components for maintenance and serviceability

UFAD Equipment. Underfloor air plenums will contain varying levels of equipment, depending on the type of plenum and spaces serviced. Pressurized plenums will contain the least amount of equipment. Special areas, such as perimeter zones, conference rooms, and zero-pressure plenums, will contain more equipment, such as fan-powered boxes. As with any equipment siting (underfloor, overhead, or otherwise) adequate clearance must be provided for maintenance (such as filter changing), repair, and removal. The O&M organization should review equipment layout to ensure access is reasonably ensured.

Other Systems and Equipment. UFAD plenums are almost always used to provide raised access floor benefits. For this reason, O&M accessibility to other than UFAD systems and equipment, such as electrical and cabling, must be ensured as well.

3 UFAD Assessment & how to get the most out of UFAD 3.1 Controllability of Systems

This chapter covers control considerations for UFAD Systems. The control and optimization of thermal comfort in the occupied zone and the amount of thermal stratification (during cooling operation) is crucial to system design, sizing, energy-efficient operation, and comfort performance of UFAD systems. This section presents and discusses recommended control strategies for effective system operation specific to UFAD systems. Due to the number of different UFAD system configurations (refer to Chapter 5), this chapter does not cover all possible control scenarios but is intended to introduce some of the basic control strategies that are frequently used in UFAD systems. Depending on the space requirements, the controllability of the setpoints and allowable ranges may differ from zone to zone. In some, the control of the parameters and values is primarily for occupant comfort. While in others, more restrictive values are required to protect property and processes. This chapter focuses on control for occupant comfort and proper pressurization of the building during both occupied and unoccupied conditions.

3.2.2.5 Pressure Reset of Plenum Supply Air

As stated previously, the majority of supply air diffusers used for UFAD applications are pressure dependent (refer to Figure 12.7 for a typical static pressure versus air quantity diffuser curve). In other words, given a specific static pressure, the diffuser will deliver a specific quantity of air. Depending on the system design, control of air volume may be adjusted to match the space load at any given time by controlling the plenum pressure with respect to the space. This may be important should the load be intermittent or variable. Modulating fan speed or discharge air dampers to maintain a predetermined supply air static pressure is a common control strategy for this scenario, especially during off peak-load conditions.

Typically this is accomplished by resetting the supply air plenum pressure based on return air or space temperature (refer to Figure 12.8 for example of supply air pressure reset schedule). The return air temperature or space temperature is used as an indication of the current load in the space. As the temperature rises, it is an indication that there is more heat load in the space, requiring more supply air to satisfy the load. This can be especially

Figure 12.8�Typical Supply Air Pressure Reset Schedule



15 of 29| P a g e

important if manual diffusers are used in the space or if there is more type one leakage through closed diffusers or other openings into that space than anticipated. Therefore, the cooling load present is much lower or higher than the current capacity being delivered.

It should be noted that careful evaluation is needed to determine the best applicable strategy for controlling air volume to the space, especially if a common plenum is used to supply air to areas with different load profiles or schedules. For example, if the supply air pressure is reset down due to overcooling of an open office floor plan, occupied conference rooms or office spaces served by the same plenum may not be able to maintain space temperature due to the lower airflow rates. In this case, it may be necessary to provide more diffusers in these zones so that adequate cooling may be maintained with lower-than-optimum design pressures. It is also possible to use zone booster fans, plenum dividers, or other means to maintain the proper volume of air to these spaces when system pressure has been reset down.

Diffuser selection should take into account different plenum pressures. For example, it would not be recommended that diffusers of different operating pressures (e.g., type “A” full flow at 0.03 in. wg [7.5 Pa] and type “B” full flow at 0.05 in. wg [12.5 Pa]) be used with the same plenum without careful evaluation.

3.2.2.6 Temperature Reset of Supply Air In some designs or climates it may be permissible to employ a supply air temperature reset schedule based on the load profile of the space (see Figure 12.9).

Much like supply pressure reset, the temperature of air can be changed while the air volume (i.e., plenum pressure) remains constant in order to better match the current load for a given zone as indicated by return air or space temperature. This is typically accomplished by resetting the leaving air coil temperature or modulating return air bypass dampers or reheat coils.

Temperature reset sometimes works better when minor adjustments are made on a seasonal basis—for example, a supply air temperature of 65°F (18.3°C) when outdoor air temperatures are above 50°F (10°C), and a supply air temperature of 68°F (20°C) when outdoor air temperatures are below 50°F.

The same caution as for pressure reset should be taken into consideration. It may be possible to satisfy the load for one space with temperature reset but negatively affect another space served by the same plenum. It may be necessary to employ plenum dividers, diffuser counts, or booster fans for these situations.

In addition, if used aggressively, temperature reset could cause an increased use of energy and make space temperature swings more dramatic. It must be noted that energy will be absorbed and released by the plenum materials (e.g., concrete slab) and could delay or even exacerbate the space conditions.

3.2.2.7 Combined Temperature/Pressure Reset

This strategy may be employed concurrently for faster zone reaction to load variation. However, the same concerns as expressed in Section 12.4.5.2 should be evaluated. It is also recommended that the reset schedules coincide with one another so that changes made to the pressure and temperature do not negatively affect the other. The potential for this combined strategy is continual hunting of dampers and valves to satisfy both scenarios. Figure 12.10 is an example of a temperature and pressure reset schedule that coincide with return air or space temperature feedback.

3.2.2.8 Variable-Frequency Drives (VFDs) and Other Variable Flow Control

When utilizing a variable volume UFAD air distribution strategy, it is important to provide a means for modulating the amount of supply air to the plenum for energy savings. This can be done by using VFDs or variable-flow-control dampers modulating based on the supply air plenum pressure.

If multiple floors or areas are served by the same air handler, both the VFD and floor dampers can operate in series with one another. It is recommended that the air handler maintain the minimum duct static necessary to supply all plenums with maximum airflow at the building’s peak demand (taking diversity into account). Individual supply air plenum (zones) dampers modulate to maintain the supply air pressure needed for the load conditions experienced by each zone. The fan speed of the air handler should be modulated with a VFD as the pressure in the main duct fluctuates due to zone dampers opening and closing to maintain pressure in

18 of 29| P a g e

the supply air plenum (see Figure 12.11. It is also recommended that the proportional integral derivative (PID) loops used are such to prevent dampers and VFDs from hunting.

It is generally recommended to serve a large plenum with multiple air injection points. As mentioned in previous chapters, this is done to minimize the effect of potential plenum supply air temperature rise. As discussed previously, each of these injection points should use a control damper controlled by the average pressure in the plenum. It is recommended that all dampers serving the same plenum be synchronized and modulated together to one common average pressure.

3.2.2.9 Economizer Cycle The supply air temperature for UFAD is higher than for overhead systems. This might lead one to conclude that economizer cycle could be used over a wider range than overhead systems, resulting in energy savings. An economizer is climate-dependent for the buildings location. Each building will have to be

evaluated to determine if economizer operation leads to savings for its location (see Chapter 8).

3.3 Acoustics Due to the elimination or minimal use of ductwork in underfloor plenums, noise generated from the operation of a UFAD system can be substantially less than that from a conventional ducted overhead system, which can lead to speech privacy issues. This reduction in commonly found levels of background HVAC noise may create a situation where active sound masking or other acoustic design measures may be required. The small volumetric fans used for fan-powered diffusers typically have low noise levels. Noise generated by fan terminal units, however, may be problematic, and attention should be paid to these devices in terms of manufacturers’ specifications, correct installation to avoid unnecessary vibrations, and other acoustic measures that can be taken.

Raised floor panels comprise a metal casing—typically galvanized steel—and core material. By introducing a solid core, such as lightweight concrete or high-density particleboard, problems with hollow sounding floors are avoided and acoustic insulation performance is improved. In terms of reaching a compromise between a sound-tight installation and the flexibility of frequent and easy removal of floor panels, any seals/mechanical-locking configurations must be durable enough to avoid degeneration from wear and tear. In addition to the panel itself, carpet-finished systems offer a good level of acoustic insulation by damping vibrations.

Sound transmission between adjacent rooms with floor diffusers served by the same plenum is sometimes cited as a concern. More performance data are needed to fully resolve this issue, but in most configurations this should not be a problem.

3.5 Plenum integrity In order for the plenum to act as an air delivery means throughout the life of the building, its ability to contain the air must be maintained.

3.5.1 Leakage testing

As the space is used, leakage can increase due to many factors, including the following:

• Degradation and shrinkage of sealing materials • Settling and movement of building materials, resulting in cracks and gap widening

• Improper replacement of floor tiles and floor utility assemblies • Breeching of the plenum

The last factor, plenum breeching, is probably the most important. The O&M entity must fully understand the importance of maintaining plenum integrity when space is modified or utilities are added or rerouted. It is recommended that a permit system be developed for all plenum-related work and that all



20 of 29| P a g e

anticipated plenum penetrations be specifically identified and inspected by the building owner’s representative. It is also recommended that signage, such as that depicted in Figure 15.1, be affixed in the vicinity of existing penetrations that are likely to be disturbed in the future.

The initial plenum installation should be leak tested during the testing, adjusting, and balancing (TAB) and commissioning process. This value can be used as a baseline to compare future leakage test results. A leakage test should be performed both prior to and after major reconfigurations. The pretest will provide an indication of the degree of increased leakage over time and help to determine how much effort must be dedicated to inspecting and resealing the plenum. See Chapter 3 for more detailed discussion of leakage and leakage testing.

3.6 Occupant satisfaction Maintaining a periodic occupant survey could be key in assisting with troubleshooting operational problems with the UFAD system. This type of survey can be helpful in determining systemic problems with the system.

3.7 Occupant training It is imperative that the occupants not only understand how to control temperature and airflow but also grasp the basic principles of UFAD. Specifically, they need to understand that room response is more gradual than what they might be used to with other systems.

See Section 15.7 for additional details related to diffuser location and adjustment.

4 System Moves, Adds, and Changes

The importance of careful design of UFAD systems cannot be overemphasized. Once a system is installed, there are few available adjustments that can dramatically alter the energy and comfort performance to correct for design flaws. Other types of remediation (e.g., replacing/adding diffusers) can be expensive. Even commissioning is complicated by the high degree of interaction between various elements of the system and the need to achieve balance between energy and comfort concerns. Among obstacles to commissioning are the following:

• Preoccupancy testing is impractical; without normal loads in the space, stratification cannot be created.

• Midseason testing is difficult due to changeovers between heating and cooling in the same zone or between zones. Cooling the interior while heating the perimeter complicates testing due to interactions between the two temperatures.

• Load conditions are difficult to measure. • Elaborate testing procedures are impractical due to (1) their complexity, (2) the inability to replicate test conditions in the field so that comparisons can be made to previous tests, and (3) high cost of testing and disruption to tenants.

• Unresolved problems with HVAC components and BMS controls—i.e., lack of complete functional testing and commissioning of BMS.

• Sequences of operation that do not conform to specifications, are inoperable, or are inappropriate for UFAD.

• Adjusting supply plenum distribution is often impractical due to difficulties of access and inability to predict the outcome.

• A wide array of approaches are used to implement a UFAD system at the tenant level, AHU level, and at plenum airflow distribution configurations. These impact interaction between interior and perimeter zones. Although there appears to be some degree of decoupling between room performance (at least on a large area basis) and the plenum temperature distribution, experience has shown that balancing comfort and control between these zones due to the high degree of interaction between them represents one of the major challenges for tuning these systems (see plenum thermal distribution section).

Assuming commissioning is done well, energy and comfort performance can be affected mostly by the following parameters: AHU supply temperature, room setpoints, diffuser placement and adjustment, and adjustment (lowering) of minimum volume settings. The goal is to improve comfort and increase stratification to optimize energy performance. These adjustments indirectly affect stratification, and each has side effects that could present other difficulties or make energy or comfort performance worse. The most effective way to ensure optimum performance is to design the system with adequate number and type of diffusers; this appears to ensure more uniform dynamic performance at relatively high stratification. For systems with serious design flaws, adding, adjusting, or relocating diffusers may be the best way to optimize performance and reduce comfort complaints. Some situations may require different approaches than others. For example, if terminal equipment is undersized (a common problem when plenum supply air temperature rise is



23 of 29| P a g e

not properly factored into the design calculations), lowering AHU supply temperature should be the focus (although increasing room setpoint will also help). However, this can exacerbate problems of comfort in interior zones (another common problem in UFAD systems).

Research results indicate that increasing the room setpoint results in increased stratification and lower energy use, but the savings depend strongly on climate. Lower energy use is not unexpected, since increasing setpoints in any system lowers airflow requirements. It has been shown that fan energy savings contribute to cooling energy savings only in mild climates where there are a large number of economizer hours. On the other hand, UFAD systems may be better suited for using an increased setpoint strategy due to the fact that stratification creates lower effective temperatures in the occupied zone than overhead systems for the same thermostat setting. Also, UFAD provides some degree of personal control that can mitigate comfort problems that may occur at higher temperatures.

Adjusting relocated diffusers may be an underused strategy to mitigate comfort problems. Survey studies have shown that few people adjust (sometimes they do not know how) their diffusers and often they are unaware that they can be moved easily. Occupant training is essential to optimizing the performance of these systems. This applies to operations personnel as well.

Lowering minimum volumes can be an effective way to mitigate comfort problems in interior zones. However, there is concern that this approach could negatively affect ventilation performance. Each system must be evaluated carefully beforehand.

4.2 Diffuser Placement With the aid of computer-aided design, interior layouts can be accurately planned, particularly the locations of diffusers in the workstations. However, due to installation tolerances and adjustments, workstation encumbrances, and personal preferences, some post installation diffuser relocation will likely be required.

The first step in ensuring occupant satisfaction is to optimally locate the diffusers. A typical 8×8 ft. (2.5×2.5 m) workstation probably has eight 24 in. (610 mm) tiles that are available for diffusers. Using an offset tile diffuser—for example, located in one 12×12 in. (305×305 mm) (quadrant of the tile—allows a significant amount of outlet adjustment. It is very important that the installer work with the O&M team and the occupants to ensure that initial diffuser location is optimized. In cases of extremely sensitive occupants, the O&M team may want to consider a mini-pilot with the occupant. This can be accomplished by leaving some carpet tiles out, and taping the floor tile joints, to facilitate moving the diffuser location until the occupant is satisfied.

6 Documentation While access, maintenance, and repair in UFAD plenums is generally easier than in overhead systems, this is predicated on the ability of the maintenance worker having ready access. Exploratory access is not conducive to UFAD plenums—e.g., a worker cannot simply lift a ceiling panel and look around. Therefore, accurate as-builts must be required and maintained that specifically identify the following:

• Equipment locations • Equipment access panel and/or maintenance component location (to help determine the approach floor tile(s) to be removed)

• All shut-off and isolation valves

If accurate system and equipment locations are maintained, workers can access these and leave less of an interruption footprint than they would with overhead systems.

All manufacturer information must be maintained by the building O&M team and made available to any outside contractors that service the floor or the plenum.
