- This form will search for words in the title OR the description. If you would like to search for the same term(s) across both the title and description, enter the same search term(s) in both fields.
- This form will search for any of the words you enter in a field, not the exact phrase you enter. If you would like to search for an exact phrase, put double quotes (") around the phrase. For example, if you search for Bike Path you will get results containing either the word Bike OR the word Path, but if you search for "Bike Path" you will get results containing the exact phrase Bike Path.
SAIC Report in the iCAP: Envelope
Associated Project(s):The SAIC report derives most of its envelope-related savings from window replacement and roof insulation, assuming that only 1 percent of campus energy can be saved by weatherization. The report did not consider changes such as entry-way retrofits to reduce heat loss during entry and exit or improvements in insulation in areas besides roofs.
SAIC Report in the iCAP: Building (Retro) Commissioning
Associated Project(s):Commissioning for existing buildings (sometimes referred to as retro-commissioning or RCx) is a systematic process for investigating, analyzing, and optimizing the performance of building systems by improving their operation and maintenance to ensure their continued performance over time. This process helps make the building systems perform interactively to meet current facility requirements.
SAIC Report in the iCAP: Fume Hoods
Associated Project(s):The campus is estimated to have between 1,700 and 1,800 fume hoods in operation at the present time. The majority of these are constant air volume (CAV) hoods without heat recovery that operate continuously. Several hundred variable air volume (VAV) hoods also exist, which are in operation only when the hood sash is raised. These hoods, however, are often operated continuously.
SAIC Report in the iCAP: Information Technology (IT) and Electrical Equipment
Associated Project(s):The SAIC report assumes very little potential for savings from the purchase of ENERGY STAR® equipment such as computers and printers. Thin client computers being deployed on campus today offer the potential for a 90 percent reduction in energy use compared to desktop computers.
SAIC Report in the iCAP: Behavioral Changes and Incentives
Associated Project(s):Although the SAIC report describes the potential energy savings from behavioral changes in its section on metering, it does not include it in its analysis. The University believes a well designed incentive and education program can reduce campus energy consumption by at least 5 percent. Such a program should seek to ensure that cost savings from energy conservation measures benefit building users (e.g.
SAIC Report in the iCAP: Other HVAC
Associated Project(s):This category includes conversion from constant air volume reheat to variable air volume, eliminating summer steam usage (reheat), heat recovery, variable speed drives for fans and pumps, and steam system maintenance (including trap replacement and pipe insulation). The target for other HVAC is 12.5 percent.
SAIC Report in the iCAP: Hot Water
Associated Project(s):This category includes using instantaneous and semi-instantaneous hot water heaters, increasing insulation on hot water tanks, utilizing recovered heat from chiller condensers and other sources, and temperature setbacks. The target for hot water is 4.5 percent.
