High Performing Buildings - Winter 2013 - (Page 5)

48 UC Davis Health and Wellness Center Student Remedy The daylight-filled three-story UC Davis Health and Wellness Center offers physical and mental health services from dermatology to stress reduction strategies for the campus’ 30,000 students. Chilled beams, a somewhat unusual design element in the United States, contribute to the project’s low annual EUI of 84.9 kBtu/ft2 and reduced the height of the building, resulting in lower construction costs. The payback period for the chilled beams was originally predicted to be 6.6 years, but since actual performance has been better than predictions, the payback period will be shorter. The building envelope’s high window-to-wall ratio (41%) allows for plenty of natural daylight, which, along with an efficient lighting design, results in electricity savings. 58 Gateway West Sustainable I Prairie Companion As a developer of commercial building controls and automation systems, Environmental Systems Inc. wanted its new headquarters near Milwaukee, Wis., to showcase the potential energy and cost savings that can be achieved through high performance design and efficient operations. The building has saved more than $82,000 in building operation and energy costs, and avoided 550 tons of CO2 production during its first 27 months of operation. Except for the photovoltaic system, all of the sustainable systems and designs offer a predicted payback of eight years or less. The building’s native prairie landscaping, a low-maintenance exterior and sustainable materials all help reduce the double-LEED Platinum project’s environmental impact. A high performance envelope and mechanical systems with heat recovery contribute to the annual EUI of 41.8 kBtu/ft2. 68 Technologies on Display The growing importance of energy efficiency and sustainability has given birth to a new generation of products and technologies. This section provides a sampler of what’s new in the marketplace. Among the new products featured are portable partitions and dividers that are made from 60%–75% recycled material and finished with a VOC-free powder coating. Also included is an LED area site light that delivers up to 98 lumens per watt and allows for multiple LED configurations with over 26,000 lumens. One option includes backlight control, reducing spill light behind the pole by up to 85%. Performing Buildings 5 Winter 2013 HigH
