From Phil_Grossman at URSCorp.com Wed Aug 20 11:00:08 2008 From: Phil_Grossman at URSCorp.com (Phil_Grossman at URSCorp.com) Date: Wed, 20 Aug 2008 14:00:08 -0400 Subject: [Trace-users] Modeling Radiant Cooling Savings in Trace Message-ID: I designed a building with radiant floor cooling. For LEED 2.2, EA Credit 1 -Optimize Energy Performance, in the submittal I used the Exceptional Calculation Method to calculate the energy savings associated with the radiant cooling. The energy savings were determined from the BTU/HR the radiant floor manufacturer advised would be saved, and associated reduced chiller load. In response to the LEED submittal the USGBC reviewer stated, "This system should be modeled in the proposed building and should not be submitted as an exceptional calculation. Assuming Trace cannot model radiant cooling directly, there are several possible workarounds that could be used to simulate the performance of this type of system that have been posted on the Bldg-Sim forum for energy modelers." I reviewed the Lists Onebuilding Bldg-Sim as well as the Trace-Users forums; I did not find a thread on how to model radiant floor cooling savings in either forum. Could someone please tell me how to model energy savings from radiant floor cooling in Trace?
