Dear All,

 

According to reference guide, compliance with this credit requires the installation of “energy meters … that can be aggregated to provide base building-level data representing total building energy consumption (electricity, natural gas, chilled water, steam, fuel oil, propane, etc.)”.

Which poses the question: is it mandatory to measure whole-building energy use (base-building and tenants) or only base-building energy use (tenants excluded)?

 

Thanks,

Hi Ricardo - we asked this exact question to the LEED Coach and their respoinse was, "Utility meters measuring the whole building's energy usage are acceptable for demonstrating compliance with the prerequisite".

Dear Shanon,   thanks for your answer. However, our problem is the inverse: we have independent power contracts for the tenants (one contract per tenant) and for the common services (base-building). However, we cannot access tenants power meters (unless we have their express authorization).   Therefore, what we want to know is if we need to share with GBCI (for purposes of v4 EAp3):  
  • whole-building energy use. If this is the case, and as referred above, we will need to ask express authorization to each tenant;
  • common services (base-building) energy use. If this is the case we won’t need to do anything special because, as referred above, we have an independent power contracts for the common services.

Yes it is mandatory as it is required for compliance with this prerequesite. You are required to provide USGBC with the whole building energy use data for the first 5 years of operation.
