Site Energy Assessment
Evaluation of 6 building sites consisting of administration, vivarium and laboratory areas. Laboratories had energy utilization indexes (EUI) that were already among “best in class” prior to the start of the project, presenting a true challenge to identify economically feasible energy reduction measures. An 18-key element assessment of the cost, quantity and categorization of total building energy use by commodity/type was conducted, including:
- Fossil fuel consuming local boilers, electrical generators, direct-fired space heaters, incinerators and other large equipment
- Purchased electrical and thermal energy
The Team developed a Utility Master Plan containing performance and components/references to conservation management and current and future maintenance needs.
- Improvements identified resulted in an efficient, practical, cost effective and robust site utilities distribution system to meet current and future needs
- At the conclusion of the study, $300,000 (9% of utility budget) in annual energy savings projects were identified and analyzed
- Laboratory HVAC was further enhanced, site utility plants (chiller and boiler) were optimized and interior and exterior lighting upgrades were presented
- Many innovative approaches included ice thermal storage, HVAC occ/unocc control in labs using lighting motion sensors and pressure independent control valves on chilled water systems
- Several alternative energy generation opportunities (AEGO) were also analyzed, including solar hot water heating, solar PV and fuel cell technology; Alternative energy savings potential totaled $400,000
- Identified available funding and incentives to provide reasonable ROI
- Identified good energy management practices in place at that site and offered recommendation for syndication at other site
