About

GHT has been practicing sustainable design for decades - before it was a buzz word or an industry standard. To align with that core value, GHT implemented a high performance design in its own office space. The project achieved LEED Gold certification under LEED 2009 (version 3) for Commercial Interiors, and reflects GHT's commitment to the AIA 2030 Challenge. This guided tour highlights the latest solutions for glare control, daylight harvesting, occupancy based receptacle switching, and other innovations.

Objectives

  1. Understand how using 100% LED lighting, occupancy sensors, and vacancy sensors helped achieve a lighting power density 40.75% below ASHRAE requirements (a total connected watt density of .59 W/SF) which, in addition to meeting Energy and Atmosphere prerequisite 2 (EAp2), earned 5 points under EAc 1.1 and another point under Innovation in Design (IDc1.2) in LEED Commercial Interiors v2009.
  2. Identify how the design team utilized an energy model to illustrate how the combination of the existing efficient base building mechanical system; a high efficiency supplemental cooling systems for the IT server room; and the reduced heat load in the space (due to the exclusive use of LED lighting fixtures) achieved a mechanical energy consumption reduction of over 15% compared to ASHRAE 90.1-2007. This approach earned 5 of 10 possible points for EAc1.3 using the performance option in LEED Commercial Interiors v2009.
  3. Discuss how the use of low flow fixtures in the core restrooms helped achieve a reduction of potable water use by 33% over the baseline, which earned 6 points under Water Efficiency credit 1 (WEc1).
  4. Recognize how the use and placement of sensors for daylight and occupancy controls, which are installed throughout the space, earned 2 of 3 possible points under EAc1.4 in LEED Commercial Interiors v2009.
