During the early design phases of the Li Ka-Shing Center for Biomedical and Health Sciences at UC Berkeley, an integrated design workshop was held with the University and included the design team, utilities compa- nies, and scientists from Lawrence Berkeley National Laboratory. The goal was to develop and evaluate energy-effi ciency options for this interdisciplinary research facility. Now completed, the building is expected to receive a LEED Gold rating. Growing Pains In a building energy modeling innovation for any Location on Campus Benches Collecting trash doesn't have to be ugly summit, Dr. Franconi outlined some prob- lems with the fi eld in an attempt to unite and energize practitioners. She points out a few issues in a pre-read paper to the summit: "To meet today's market needs, the number of energy modeling practitioners has increased dramatically in a short period of time. These practitioners must follow complex modeling and reporting procedures, and very few have received formal training. Additional pressure is placed on the process since the modeling timeline is usually abbreviated, to coincide with the building design schedule. "During the rapid growth of this indus- Bike Racks — durable, secure parking ® try, professional organizations, national labs, and even private consulting fi rms, have all made great contributions to the fi eld of energy modeling. Despite these intentional (and often self-funded) efforts, there has been little collaboration amongst these various stakeholders, and many op- portunities still exist to increase the effec- tiveness of modeling to support low-energy building design and operations." The Colorado report also points to an important issue. "Energy models are excel- lent tools for indicating relative changes in energy use comparisons between design 22 COLLEGE PLANNING & MANAGEMENT / AUGUST 2012 options and of relative energy use. How- ever, design phase energy models which are not calibrated with actual operating data do not predict absolute energy use during occupancy. Additionally, the energy model does not have the ability to accurately pre- dict fl uctuations in occupant behavior or utility costs. When compared to the energy model, atypical weather and changes to scheduled use are often the two largest drivers to a building's performance." Dr. Crawley points to an example. "I had a friend who used energy modeling for a public library project he worked on. The original program called for the library to be open from 8:00 in the morning until 6:00 at night. When the client noted that the building was using much more energy than predicted, my friend came back and saw that the library was such a success that it was being used from 6:30 in the morning 'til 10 at night. He recalibrated the numbers and the modeling matched the energy use." "You need the most robust modeling to effectively predict performance along with good data from the design team, user groups, and the owner," agrees Dr. Fran- coni. "Then for the best results you should stick to the model mantra, 'do it early and do it often.'" CPM WWW.PLANNING4EDUCATION.COM PHOTO © ROBERT CANFIELD, COURTESY OF ZGF ARCHITECTS
