Fluorescent. Our design strategy is to standardize on the same type of fluorescent lamp type throughout the building included in this project. We have selected a non-proprietary proven lamp and ballast combination that will provide the greatest performance and energy savings of any of the lighting systems considered. The premium grade electronic ballasts we propose are of a high-efficiency design, which is a step above the standard grade electronic ballasts more commonly found in low bid construction projects. These ballasts provide a greater level of efficiency over the standard ballast and also incorporate an intelligent voltage capability allowing the ballast to be used on both 120v and 277v applications. The proposed T8 lamps are a premium high lumen, extended life type that again yields better results than the standard grade. For this project we have selected a 25-watt energy saving lamp. The proposed lamp and ballast system will provide the greatest energy savings of the various lamp/ballast options explored, and will additionally allow us to improve efficiency on the large quantity of existing T8 linear fluorescent fixtures with instant start ballast by re-xxxxxxx them with the latest in T8 technology and re-ballasting with low power ballasts. This T8 retrofit strategy will allow us to maintain recommended light levels while still providing a reduction in energy usage in all T8 fixtures and still standardize lamp types. Fluorescent fixtures with broken lamp tombstones will have the tombstones replaced at no additional cost. All fixtures retrofitted will be dry wiped to remove dust and particulate matter to improve fixture lumen efficiency. Occupancy Sensors A total of (277) occupancy sensor has been proposed throughout the facility including gymnasiums and multipurpose areas. In areas such as gymnasiums that have gone from HID fixtures to fluorescent occupancy sensors will be installed that can be adjusted to provide a shut off delay of up to twenty minutes to eliminate rapid or excessive cycling of lamps. Designated vending machines with non perishable snacks and beverages have also been addressed with occupancy based controls to reduce electrical consumption during low occupancy periods.
