figuRE 6 bAseline, ProPosed And ActuAl energy use 2008–10 About the Authors Cole Roberts, P LEED AP Associate .E., , Member ASHRAE, is an associate principal at Arup. Amit Khanna, Associate Member ASHRAE, is a senior consultant at Arup. Actual metered data has shown savings to be even greater as the building use has increased (Figure 6). The resulting emissions reduction is estimated to be nearly 1,200 metric tons in the first year of operation. In response to financial success and positive feedback from users, Stanford has since mandated that a heightened level of performance be pursued on all subsequent buildings in the 2.4 million square feet capital expansion plan. The directive from the board of trustees is that all buildings target a minimum of 30% energy and 25% water reduction. The design team has continued its relationship with the building users and Stanford Energy & Sustainability staff through detailed performance discussions and guest lecturing, underscoring the strong relationships that formed over the course of design and construction. • Actual vs. theoretical data: which would you rather have? Knowing the actual thermal performance of the building envelope assures compliance to energy codes. Your Butler Builder ® can assist you in providing extremely accurate estimates of thermal performance for Butler building systems. 1" Actual 8' x 10' roof and wall assemblies are tested in the Butler ® Guarded Hot Box1.375" accurate to provide insulating information, rather than theoretical data provided by most building product manufacturers. That means Butler ® building systems deliver the energy efficiency they promise. For more information about the advantages of Guarded Hot Box testing, visit butlermfg.com/GHB. A state-of-the-art computerized data acquisition system collects information from up to 300 sensors used to measure the temperatures, humidity, airflow, and the total energy consumed during the 3-day test period. The results are expressed as the actual U-factor performance of the assembly. ©2011 BlueScope Buildings North America, Inc. All rights reserved.
