Intended primarily but not solely for use at the postsecondary level, this curriculum guide contains five units on energy efficiency that were designed to be incorporated into an existing program in architectural drafting. The following topics are examined: energy conservation awareness (residential energy use and audit procedures); residential energy consumption (space heating, ventilating, air-conditioning, hot water heating, lighting, and appliances); design considerations for residential energy efficiency (site orientation, building type, room arrangement, location of openings, and building codes); residential construction practices and materials (building and insulating materials, construction methods, infiltration, vapor barriers, and moisture control); and energy saving devices and methods (ventilation, lighting, solar systems, stoves and fireplaces, wind generators, heat sinks, and moveable insulation). Covered in each lesson are unit rationale, necessary advanced preparation, anticipated instructional time, guidelines for implementing the unit, unit activities, and unit references. (MN)
