Our project is a multiple buildings project on a historic site in California. This proposal requests approval of the following Measurement and Verification (M&V) approach for this project to satisfy LEED-NCv2.2 AGMBC EA credit 5. The project scope covers 34 buildings in total with a mix of new construction and renovation. Features of the building systems include, but are not limited to, the following: New Lodging (13 buildings): in-floor radiant heating toilet exhaust fans boiler, pumps, expansion tanks HVAC controls gas fireplace inserts domestic water systems lighting controls split-system air-cooled DX heat pumps (in 2 of the buildings only) New Healing Arts Center (HAC) building: in-floor radiant heating & cooling toilet exhaust fans boiler, pumps, expansion tanks chiller heat recovery ventilator fan coils relief air system radiant ceiling panels hydronic panel radiators HVAC controls domestic water systems lighting controls fire/smoke dampers Historic Buildings 547, 549, 546: gas-fired duct furnace exhaust fans domestic water systems lighting controls HVAC controls Historic residential buildings (15 buildings): boiler, pumps, expansion tanks radiators, hydronic & gas-radiant exhaust fans radiant ceiling panels domestic water systems lighting controls HVAC controls Historic common buildings (5 buildings): boiler, pumps, expansion tanks boiler power ventilators radiators exhaust fans make-up air units split-system air-cooled DX heat pumps relief air system fire/smoke dampers unit heaters HVAC control The project team, in working with the owner, has identified that the best approach to perform M&V on this project will be to use Option B. However instead of developing an M&V plan per building as prescribed by the IPMVP Volume 3, the project team intends to develop a single M&V plan based on system type. This reduces the number of M&V plans generated to drop from 34 (at one per building) to 6 (one per system type and one variation) as identified below - 1. In-floor radiant heating systems 2. In-floor radiant heating systems with DX cooling 3. In floor radiant heating and cooling systems with heat recovery ventilators 4. Gas-fired duct furnaces 5. Radiators and gas radiant heating system 6. Hydronic radiators combined with air-cooled DX heat pumps The following items will be included as standard elements to all M&V plans - 1. All auxiliary energy consuming equipment attached to any system as applicable 2. HVAC control points and controls applicable to each system In addition to the above mentioned inclusions, the team will also generate a separate system level plan to address - 1. All lighting system and lighting controls 2. Water consumption - split by domestic and heating water 3. Gas consumption for fire place inserts. As a general guideline all M&V plans will cover all aspects of the sections 3.2 and 4.3 of the IPMVP Volume III (2003). Given the unique nature of this project (historical, 34 buildings) the owner requests the USGBC\'s permission to use this alternative compliance path. The proposed approach is the most effective (cost and performance) means to capture data that supports systems evaluation and building operation decisions.
The approach described to achieve EAc5 across the 34-building complex is acceptable in the context of Option B. Although it is implicit in your description, be sure to explain in detail in your M&V Plan how your metering approach will enable investigation at the building level. In other words, while your plans may be organized at the system level, you will need to be able to isolate lighting loads at each building, for example.Update April 15, 2011: Please note that all 2009 projects in multiple building situations must follow the 2010 Application Guide for Multiple Buildings and On-Campus Building Projects, located here: https://www.usgbc.org/ShowFile.aspx?DocumentID=7987. 2009 project teams should check this document for up to date guidance on all multiple building issues.
