We would like to ask something regarding a comment from a reviewer for EAc1, this is a rather vague comment in our view. Our project consist of around 5 buildings connected through a ground water loop supplied by a well, the cooling/heating process occur at a project scale not a campus scale. The reviewer said: "It appears from the description in the Commissioning Report provided in EAp1: Fundamental Commissioning that a campus energy source is used for the Proposed Case building heating and cooling. Note that all New Construction, Schools, Core and Shell, and Commercial Interiors projects registered with the USGBC on or after 05/28/2008, and using district thermal energy, are required to follow the guidance of the document "Required Treatment of District Thermal Energy in LEED?NC version 2.2 and LEED for Schools, version 1.0" (DES v1) dated May 28, 2008 which can be accessed at: www.usgbc.org/resources/des-district-energy-systems-guidance-v22-and-v20.... Optionally, in lieu of following the required version 1.0 guidance, the project may choose to follow the guidance of the document "Treatment of District or Campus Thermal Energy in LEED V2 and LEED 2009? Design and Construction" (DES v2) dated August 10, 2010 which can be accessed at: www.usgbc.org/resources/des-district-energy-systems-guidance-v22-and-v20.... If following version 1 of the District Thermal Energy guidance, please provide a Step 1 EAc1 template and supporting documentation if pursuing 2 points, or both a Step 1 and a Step 2 template and supporting documentation if pursuing more than 2 points, and provide sufficient information to show that the District Energy Requirements document has been appropriately applied to the project. If following version 2 of the District Thermal Energy guidance, please follow the requirements of either Option 1 or Option 2, as appropriate for your situation. The submitted LEED review documentation must clearly state which method, District Thermal Energy guidance v. 1.0 (DES v1 - May 2008) or District Thermal Energy guidance v. 2.0 (DES v2 - August 2010) was used". The commissioning Report is not very clear on this, the Cx Agent does not say that a campus energy source is used for the Proposed Case, but it only says the ground water source well pumps (campus) are out of his/her scope (which by the way are not energy source in any way). Thus we cannot follow any of these guidances suggested since the cooling and heating are provided at a project level instead of a campus level , given that the groundwater is considered a thermal storage only in this case. Has anybody had any experience on this type of comment?
