I have a project consisting of one hotel and 24 chalet, we are attempting EAc5 monitoring and verification under LEED NC V 2.2 The project will be operated by one operator which will be responsible of all operational issues, such as housekeeping, food and beverage, maintenance ,.etc. The project is being supplied by its need from electricity, from one substation installed specifically for this project, also the gas and water will be supplied from one main gas and water tanks installed specifically for this project. Hence, the operator will pay against the energy and water consumption for the whole project, while the guests of the chalets will not be charged for their energy and water consumption since it will be covered in the main charge which they are paying. The buildings (chalets) are simple buildings, and the project team determined to follow option B as specified in the International Performance Monitoring and Verification Protocol IPMVP to develop the M&V plan and meeting the intent of this credit. The question is: To meet the intent of this credit, can the project team consider installing one main energy meter for each type of energy (electricity, Gas and water)? knowing that the M&V plan will be created and implemented as required.
Based on the description of the project, installing one main energy meter for each utility (water, electricity, gas, etc.) servicing the entire project would be acceptable, as long as all of the systems affecting an energy conservation measure (ECM) are capable of being fully measured on a continuous or periodic basis. In addition, please note that the metering, measurement (without stipulation) and verification protocols listed in the M&V plan must conform to guidance offered under IPMVP Option A&B (Sections 4.2 through 4.3.1). Applicable Internationally.
