An administration building is being constructed using sustainable design features. Our firm is utilizing thermal insulation R values in the building envelope (R-20 walls and R-25 continuous roof insulation) containing both cavity wall insulation and foamed-in-place back up wall concrete masonry block insulation. The roof is being constructed using a continuous structural insulated panel roof system, commonly known as SIPS, supported on trusses or exposed glulam wood beams.
Use of clerestory windows provides daylighting to the administration common spaces with solar shades to reduce summer solar gain. Remote clerestory windows with electric operators allow the summer heat to dissipate through the high window openings, while cooler air comes through the first floor windows, creating a natural gravity ventilation path.
From an energy perspective, high-efficiency lights were designed along with lighting controls to turn off the interior lighting spaces when not in use. Indoor air quality was also addressed with interior materials and coatings with low volatile organic content.
