EAp2 X Multiple Building

Dears, We would like to solve out some questions about the LEED EB certification process. In this case we have a boundary area with 4 towers. Tree towers are already operating and one is under construction. Of the tree operating towers, only two of them are being certified. In this case, all the structure of external parking lots, landscaping, roads and grounds are shared with the four towers and will be 100% considered in the certification scope. Follow on the next lines a more detailed explanation of the situation and our questions about this case: 1)Eap2 – Minimum Energy Efficiency Performance The areas for Tenants have individual metering for lighting and plugs for each tower. The HVCA systems (Chiller, Fans, Pumps, etc…) are shared and the measurement is made considering the total consumption. All lighting from common areas such as parking lots, facades, elevator halls, grounds and others are also measured together. To determine the consumption to be added in Energy Star´s Manager Portfolio we have considered the total measured consumption from the areas of the Tenants for each tower (1). For common consumptions we have considerate the total measured value multiplied by the percentage of built area less the area of the tower that is not pursuing certification (2). (2) Considered consumption = Total consumption * 77,00% Note: 77,00% = the percentage area from the two towers under certification in relation to the total Gross Square Footage area for the Three towers in operation. The total consumption for each tower was obtained by the some of the measured individual consumption for each towers that are pursuing LEED Certification plus 50% of the common consumption (2). Calculation report: (3) Monthly consumption of each tower = Tenant’s Consumption (1) + 50% of the common consumption (2) Questions: A) Is the methodology above correct to demonstrate compliance to EAp2? B) Is it necessary create two ratings for these two towers or we can use the same rating for both towers in Portfolio Manager? Yours sincerely,
