This second volume of the Advanced Simulation Guidebook series is intended to teach readers about the high performance building process for commercial new construction. The goal of the high performance building process is to create buildings that meet owner and occupant needs in terms of energy efficiency, thermal comfort, and other sustainability areas-and do so in a way that reduces the necessary design effort and construction cost impact.

Commercial new construction projects in California have a long history of achieving exemplary energy efficiency, particularly when compared to the level of efficiency typical of projects in other parts of the United States. Since the introduction of California's Title 24 Standards in 1978, Golden State projects have been required to comply with one of the most stringent energy codes in the world. The performance requirements in Title 24 have been continually revised over the years as new energy technologies and design techniques have become available. The current Title 24 Standards require a high level of energy efficiency, and compliance with these standards is not a "given" without employing an integrated design process and efficient building systems.

Today, many projects are pursuing even higher levels of energy efficiency than what is required by Title 24 as a result of participation in utility-sponsored incentive programs, such as Savings By Design. Projects may also be seeking certification under the " Leadership in Energy and Environmental Design" (LEED) or the "Collaborative for High Performance Schools" (CHPS) green building rating/certification systems.

The first part of this guidebook addresses the high performance building process, and how energy modeling can be used to help project stakeholders make better informed design decisions. Specific ways that energy modeling can be used to support the high performance building process during each design phase are discussed. The second part of this guidebook addresses program-specific documentation requirements for Savings By Design, LEED for New Construction version 2.2. (LEED-NC-2.2), and California CHPS 2006 (CA-CHPS-2006). There is a wealth of information on energy modeling, advanced building systems, and related topics available free-of-charge at the Energy Design Resources website ( A list of free resources that may be of interest is presented in the "For Additional Information" section at the end of this handbook.
