Above Students approach the main entrance to the building from the west. The building’s east-west axis maximizes north and south exposures, while minimizing east and west exposures. Right The Health Education and Promotion department waiting area on the third floor provides a view of the green roof over the main entry pavilion. Student representatives on the building committee strongly advocated for this project element. This is the campus’ first green roof, and it gives the campus O&M staff an opportunity to experiment with this technology on a small scale. © Bruce Damonte Photography roads through campus, that forms the east boundary of the site. The main entry is on the northeast corner of the building, reaching out to bicycle riders and pedestrians who make their way onto the site off the sidewalk along La Rue. An existing parking lot to the north serves the building, so no new parking was needed; however, preferred parking spaces are designated for electric vehicles. Combining a welcoming outdoor space and storm water management strategies, the southern portion of the site is dedicated to a wellness garden that acts as a storm water retention area and bioswale. The region’s climate consists of hot, dry summers and cool, rainy winters. The H&WC is oriented along an east-west axis to maximize north and south exposures and minimize east and west exposures. The north elevation is almost all 50 curtain wall glazing, which maximizes the introduction of soft natural light into the band of waiting areas located along the north perimeter of the floor plan. On the south elevation, punched windows with integral sunshade devices control the intense southern sun. The east and west elevations have vertical sunshade devices to control glare and address the rising and setting sun. Energy Efficiency Building Envelope. Even with a window-to-wall ratio of 41.2%, the building envelope includes features that contribute to energy efficiency and, in the case of its green roof, n at u r a l g a s u s E 12,000 10,000 therms 8,000 6,000 4,000 2,000 0 Apr 10 May 10 Jun 10 Jul 10 Aug 10 add a unique design element among campus buildings. Wall construction consists of 2 × 6 metal studframed walls with R-19 insulation. Thermal bridging through the walls occurs due to the use of conductive metal studs, and the resulting effective U-value is 0.18. A built-up roof with 4 in. rigid insulation sits on top of the metal deck. Outside, the campus’s first green roof helps reduce the heat island effect. Its effective U-value is 0.04. Total glazing area for the building is approximately 11,700 ft2. A combination of fritted and nonfritted glass helps balance performance and cost, with the solar heat gain coefficient (SHGC) ranging APril 2010–MArch 2011 Sep 10 Oct 10 Nov 10 Dec 10 Jan 11 Feb 11 ASHRAE/IESNA Standard 90.1–2004 Proposed ASHRAE/IESNA Standard 90.1–2004 Calif.
