February 11, 2013 Subject: TRACE™ 700 v6.2.10 Compliance with ANSI/ASHRAE Standard 140-2007 Dear TRACE User:

We are pleased to inform you that TRACE 700 v6.2.10 was tested in compliance with ANSI/ASHRAE Standard 140–2007, Standard Method of Test for the Evaluation of Building Energy Analysis Computer Programs. Test results, supplemented by graphs and explanatory notes, accompany this letter. As you may know, ANSI/ASHRAE/IESNA Standard 90.1, Energy Standard for Buildings, Except Low-Rise Residential Buildings, stipulates that any computer program that is used to demonstrate code compliance via the performance path’s Energy Cost Budget Method must be tested in accordance with Standard 140. TRACE 700 v6.2.10 has completed the BESTEST validation for calculation and comparison with similar analysis programs as required by ASHRAE Standard 140. Standard 90.1 defines minimum requirements for the design of energy-efficient buildings and is used by many state and local code-writing bodies as the “standard of care” in their jurisdictions. Building-energy simulation programs, such as TRACE 700, are used to estimate the difference in energy costs between the design- and budget-building models specified in Section 11 of Standard 90.1. If you have questions about the testing documentation that accompanies this letter, or about any of Trane’s design and analysis tools, please contact our C.D.S. Support Center by phoning (608) 787-3926 or e-mailing [email protected]. Best regards,

Charles Jelen ASHRAE Standard 140 Coordinator Trane C.D.S. Attachments: Results and modeling notes from Standard 140 testing of TRACE 700

STANDARD 140 OUTPUT FORM - MODELING NOTES SOFTWARE: TRACE 700 Simulated Effect (1): Loads modeling Optional Settings or Modeling Capabilities: Cooling Load Methodology Options: TETD-TA1 -- Response factor TETD/Time-Averaging method CLTD-CLF (ASHRAE TFM) -- Exact Transfer Function Method TETD-TA2 -- Approximate TETD/Time-Averaging method TETD-PO -- Approximate TETD with Post Office Weighting CEC-DOE2 -- Exact TFM method with CEC\DOE 2.1c constraints RP359 -- ASHRAE Research Project 359 Method RTS (ASHRAE Tables) -- Radiant time series coefficients based on 2001 Hof table lookup RTS (Heat Balance) -- Radiant time series coefficients based on heat balance Setting or Capability Used: RTS (Heat Balance) -- Radiant time series coefficients based on heat balance Physical Meaning of Option Used: Each room’s solar and non-solar Radiant Time Series values are calculated based on the rigorous Heat Balance method described in the 2001 ASHRAE Handbook of Fundamentals using algorithms found in the ASHRAE Toolkit for Building Load Calculations. This TRACE load methodology also calculates the amount of solar gain lost through retransmission back out through the window. These heat balance-derived RTS values are implemented in a manner similar to custom weighting factors used by the DOE 2.1 energy analysis program. Simulated Effect (2): External heat transfer Optional Settings or Modeling Capabilities: Outside Film Methodology Options: Constant (as defined in construction library) Vary with wind speed: per the 1985 ASHRAE Handbook, P. 28.5 Vary with wind speed & direction, and ΔT: per the MoWiTT model

Vary with wind speed & direction, ΔT, and surface roughness: per the TARP model Setting or Capability Used: Constant (as defined in construction library) Physical meaning of option used: The internal and external surface coefficients were set equal to the values provided in the standard.

DOCUMENT BELOW THE REASONS FOR OMITTING RESULTS List the case(s) where results were omitted, and which results were omitted for the case(s): CASE960 – CASE960 models a passive solar sun room using a modified Trombe wall. In order to model this configuration the associated algorithm would need to compute: a) The hourly proportion of solar radiation absorbed by the individual sunlit surfaces within the sunlit portion of the Trombe wall b) The effect of introducing infiltration in the Trombe wall section c) Adjacent space heat transfer between the Trombe wall and the interior room. The required inputs to model this type of configuration are not available in TRACE.

STANDARD 140 – EXTENDED COMMENTS – E100 TO E200 Action taken to update code: 1) The TRACE room humidity ratios were half of the benchmark results, a result of the TRACE coil curve algorithm being unable to distinguish a "dry coil" condition. This routine (SSCRV.FOR) was therefore modified to test for a dry coil condition by estimated the hourly coil apparatus dew point, ADP. When the hourly coil entering dew point, CEDP > ADP, this indicates a dry coil and so CLWC = CEWC, and only sensible cooling can occur. 2) The TRACE condenser fan energy consumption was found to be excessively higher than the benchmark values. This occurred because TRACE was not taking into account the fact that when unitary equipment cycles off for a portion of an hour; the condenser fan must cycle off the same amount. The CONDFN.FOR routine was therefore modified such that when OADB > 95F, the max condenser fan demand is multiplied times the cycle on ratio. The off cycle time reduction could not be applied to other ambient conditions because of other assumptions built into the routine. 3) The TRACE System Simulation does not currently have the capability to vary the cooling coil capacity as a function of inlet conditions (this is only available in the Equipment Simulation). TRACE simply assumes that the cooling coil can supply the SADBc (and associated CLDBc) calculated at design for all entering conditions. Therefore, in order to get better agreement between TRACE and the benchmark programs, the DSADBc Min/Max values were calculated for each E-series case. Other notes: 4) The agreement between the Envelope latent and sensible values match very closely for all E-cases. This means that the envelope and internal load values defined in the TRACE files were correctly input. 5) After the SADBc Min/Max values were specifically input for each of the E-Cases in alternative 1, the results for the evaporator, supply and condenser fans match the benchmark programs very closely.

STANDARD 140 – EXTENDED COMMENTS – E300 TO E545 Action taken to update code: 1) The TRACE equation for Solair temperature used a constant term (21 Btuh/ft2 ) to represent the longwave correction ΔT, i.e., SOLAIR(IHR)= OADB(IHR) + RTOT * ALPHA / HOSLAB(IHR) - (21/ HOSLAB(IHR)) * PCSKY. However, this term should actually vary with the outside surface emissivity (see p. 30.22 of the 2005 ASHRAE Handbook of Fundamentals) and so was changed to: SOLAIR(IHR)= OADB(IHR) + RTOT * ALPHA / HOSLAB(IHR) - (EMISS*20 / HOSLAB(IHR)) * PCSKY where PCSKY is 0 for vertical surfaces and 1 for horizontal surfaces. This change has no effect on wall heat transfer but will have a slight effect on roof heat transfer since EMISS defaults to 0.9 and HOSLAB typically is 3 Btu/(hr-ft2-F) and so the -EMISS*20/HOSLAB term yields (-0.9*20/3) = -6 F TD vs. (-21/3) = -7 F TD for the old method. However, in the Standard 140 E300-545 cases, both HOSLAB and EMIS were defined as very small to model an adiabatic surface and so the (-21 / HOSLAB(IHR)) term yielded a high negative value. Other notes: 1) The Standard 140 test cases E300-500 and H100-245 assume an unrealistically low thermal mass of near zero for the base case building which causes instability in the TRACE temperature drift model. To correct this, the default Room Mass for these cases was changed from "Time delay based on actual mass" to "Light (30 lbm/ft2), 3 hr. lag". 2) As noted for the E100 to E200 comments, the TRACE System Simulation does not currently have the capability to vary the cooling coil capacity as a function of inlet conditions (this is only available in the TRACE Equipment simulation). TRACE simply assumes that the cooling coil can supply the SADBc (and associated CLDBc) calculated at design for all entering conditions. 3) As noted for the E100 to E200 comments, the TRACE System Simulation does not currently have the capability to vary the cooling coil capacity as a function of inlet conditions (this is only available in the TRACE Equipment simulation). TRACE simply assumes that the cooling coil can supply the SADBc (and associated CLDBc) calculated at design for all entering conditions which causes the fan energy to be larger than necessary. Therefore, in order to get better agreement between TRACE and the benchmark programs, the DSADBcMin/Max values were calculated for each these cases and input as follows: E500=17C, E510=16C, E520=7.1C, E522=20C, E525=27C, E530=17C, E540=15C and E545=27C. 4) The capacity and ambient unloading curves used with the Air cooled split condenser used for the E300-E545 datasets were imported from the EnergyPlus dataset provide by Linda Lawrie. Since EnergyPlus does not model the condenser fan separately but TRACE does, the unloading curves could be improved for TRACE by eliminating the

condenser fan kW from the raw data used to generate those curves. The power unloading curve is the same as was used for the E100 series.
