"This Guide applies to K-12 (classified as elementary@ middle@ and high schools) buildings with administrative and office areas@ classrooms@ hallways@ restrooms@ gymnasiums@ assembly spaces@ food preparation spaces@ and dedicated spaces such as media centers and science labs. This Guide does not consider specialty spaces such as indoor pools@ wet labs (e.g.@ chemistry)@ ""dirty"" dry labs (e.g.@ wood-working or auto shop)@ or other unique spaces with extraordinary heat or pollution generation. It is primarily intended for new construction@ but it may be equally applicable to many school renovation@ remodeling@ and modernization projects. Included in the Guide are recommendations for the design of the building envelope; fenestration; lighting systems (including electrical lights and daylighting); heating@ ventilation@ and air-conditioning (HVAC) systems; building automation and controls; outside air (OA) treatment; and service water heating (SWH). Additional savings recommendations are also included but are not necessary for 30% savings. Additional savings recommendations are provided for electrical distribution@ plug loads@ renewable energy systems@ and using the building as a teaching tool. The recommendation tables do not include all the components listed in@ ASHRAE Standard 90.1-1999. Though this Guide focuses only on the primary energy systems within a building@ the underlying energy analysis presumes that all the other components are built to the criteria in Standards 90.1 and 62.1. Certain aspects of energy-efficient school design@ including steam heat@ modular classrooms@ vehicle and maintenance areas@ domestic water well piping@ kitchen process loads (e.g.@ ovens@ coolers@ freezers)@ and sewage disposal are excluded from the Guide. Significant energy-efficiency opportunities may be available in these areas@ and Guide users are encouraged to take advantage of these opportunities and treat them as bonuses beyond the 30% target. In addition@ the Guide is not intended to substitute for rating systems or references that address the full range of sustainable issues in schools@ such as acoustics@ productivity@ indoor air quality (IAQ)@ water efficiency@ landscaping@ and transportation@ except as they relate to energy use. This Guide is not a design text; rather@ it presumes good design skills and expertise in school design."
