Bill and Sue Gross Hall Features

BUILDING ENVELOPE

Concrete structural frame, high thermal mass. Light-colored concrete design (reducing heat gain) Ultra-high-performance glazing (Solarban). Shaded entry glazing via setback and overhang elements T-24 Cool-roof material R-30 roof insulation Sun-shades on south and west exposures Landscape belts at building perimeters reducing heat and reflection impacts

LIGHTING

Dimmable lighting systems for meeting spaces Perimeter day-lighting controls. Occupancy controlled office, laboratory, and fume hood lighting. LED Task Lighting Efficient lighting layout, T-24 design:

o With lighting control credits: Offices –  0.49 w/sf Labs –    0.66 w/sf Overall Conditioned Space – 0.61 w/sf

ELECTRICAL

Low power design elevators High-Efficiency Transformers 

MECHANICAL SYSTEMS

Out-perform Title 24 by energy performance by more than 36 percent Operable windows with air conditioning interlocks NEMA premium efficiency motors Use of variable speed drives for AHU’s, pumps, and lab exhaust fan motors VAV Laboratory air system Aircuity smart-controls for laboratory air systems Minimum of 4 air changes per hour in occupied laboratories Minimum of 2 air changes per hour in un-occupied laboratories Energy efficient VAV fume hoods Low velocity air handling units – 350 fpm face velocity Low pressure drop laboratory air system design Low velocity air distribution system Low velocity exhaust ductwork Use of duct liners in lieu of sound attenuators Rest Room occupancy controlled ventilation

WATER CONSERVATION MEASURES

Stormwater runoff control Drought tolerant landscape selection Reclaimed irrigation water Water conserving plumbing fixtures

o Ultra-low flush Urinalso Dual-flush Toilets

UCI Smart LabSmart Lab

Stretch GoalsOut-perform

ASHRAE 90.1 (CA Title 24, Part 6)

20% UCI currently outperforms 2005 Title 24 standards by > 20%. Recent

construction achieved 33%. Expect to out-perform 2008 Title 24 standards (effective 1/2010) by 20% or more.

Outperform 2005 CA Title 24 by 50%

Occupied lab air-changes/hr. (ACH)

6 ACH 4 ACH w/centralized demand controlled ventilation (CDCV), pilot testing

4 ACH w/CDCV

Unoccupied air-changes/hr. w/setback

No setback 2 ACH with occupancy sensor & CDCV in fume hood driven lab, pilot testing

2 ACH with occupancy sensor & CDCV

Fume hood – face velocities

(occupied)

100 FPM Use low flow fume hoods. Our initial study encouraging at 70 fpm face

velocity. Awaiting Cal/OSHA variance to further test.

60 FPM (using low flow fume hoods

where applicable)

Fume hood – face velocities

(unoccupied)

60 FPM Use low flow fume hoods. May be achievable in fume hood driven lab to

reduce to 40 FPM.

40 FPM (using low flow fume hoods

where applicable)Fume hood

auto sash closersNone Other features more cost-beneficial

when hood density is not highIn fume hood-driven

lab needs to be standard feature on

new hood.Exhaust stack

discharge velocity~3,000 FPM

w/bypass air (typical)

Increasing stack height (~ 5 ft.) with lower stack velocities (~1,600 FPM) is

a typical tradeoff with high benefit

Optimize stack height and stack velocity

based on wind tunnel study of existing

facility with no by-pass air.

Lab illumination power density

0.9 watt/SF 0.66 watt/SF power density currently achievable through use of light-sensing

auto dimmers

0.6 watt/SF w/LED task lighting

Daylight sensors for fixtures near windows

Yes See above Yes

Energy Star freezers and refrigerators

Yes Exchange program in effect for older refrigerators. Required by policy for all

new equipment purchases.

Yes

Duct noise attenuators Few<0.1 in. w.g. of

static loss

None - Reduce noise by using two smaller fans in parallel instead of a

single larger fan.No attenuators used due to large

associated pressure drop. Provisions in ductwork for future attenuator, if

necessary

None

Air-handler/filtration airspeeds (max.)

400 ft/min 350 ft/min currently achievable (Example: Gross Hall)

300 ft/min.

Total laboratory ventilation system

pressure drop (supply+exhaust)

6 in.w.g. 5.75 in. w.g. currently achievable in new construction

< 5 in.w.g. (including dirty filter allowance)
