A high-performance building doesn’t just have “better windows” or a “high-efﬁciency mechanical system.” For example:
- Glazing: Provides daylight, but also brings glare, heat gain, and heat loss. Size, placement, shading and speciﬁcations of windows and skylights should be carefully integrated.
- Lighting: The full energy savings from efﬁcient lamps and ballasts are only realized if the layout is optimized, the system is integrated with daylighting zones, and has the right controls
- Mechanical: Systems can be right-sized if a variety of heat gains are reduced, but only if the team has the information early enough in design.
- Photovoltaics (PV): Increasing the energy efﬁciency of a project allow a smaller and less costly PV system to provide the same amount of renewable offset.
