"The goal of this paper is to demystify energy modeling for design and facilities-planning professionals. By “energy modeling,” I mean using computer-based tools to simulate the energy use of a building throughout an entire year of operation. This is commonly referred to as “annual energy use simulation.”
The U.S. Green Building Council’s Leadership in Energy and Environmental Design Rating System (LEED™) requires energy modeling to assess the energy use of a building and to quantify the savings attributable to the proposed design. In many cases, architects and building owners are inexperienced with energy modeling and don’t know how to harness this powerful tool to inform the design and decision-making process. Properly used, energy modeling can help optimize the building design and allow the design team to prioritize investment in the strategies that will have the greatest effect on the building’s energy use. This paper seeks to put architects and facility owners in a position to effectively direct the modeling process and evaluate the validity of the output presented."
