The use of energy modeling has increased significantly due to the growing popularity of the LEED (Leadership in Energy and Environmental Design) program. The LEED program, developed by the US Green Building Council (www.usgbc.org), encourages sustainable and energy efficient design, which is determined by comparing an energy model of the building's design with a model of the same building built to ASHRAE 90.1 minimal efficiency requirements. Although performing a model is required for LEED buildings, it is a strategy that should be used in all building designs, to ensure the best decisions are being made regarding energy efficiency.

Incorporating energy efficiency into building design may be the strategy that provides the best return on investment in the entire process. Efficiency can have a much greater impact during the design process for new construction than in existing buildings, since annual savings are compared to incremental increases in cost, rather than whole replacement costs. Many smart design strategies don't result in any additional up front costs. For example, if you start with a standard building design, and decide to make an investment in high-efficiency windows, you may spend a small incremental additional cost up front. However energy efficient windows, in addition to reducing energy consumption, also reduce the peak cooling and heating loads, therefore the cooling and heating system could potentially be downsized. In many cases, the incremental costs for high performance windows are more than offset by lower initial central plant costs, resulting in a net reduced first cost.

Energy Simulation modeling should be integrated in the very early stages of schematic design. Using default assumptions for mechanical systems and building envelope characteristics, you can run a simulation with different orientations of the building to determine the one with the lowest predicted energy costs. Once this has been determined, similar types of analyses can be run comparing different wall types, window configurations, roof types, and even design characteristics such as window overhangs and skylights. During Design Development, the energy model can be used to quantify savings from strategies like daylighting control, window characteristics, shading devices, and air supply strategies such as demand controlled ventilation. Since all buildings have a limited budget, the ability to quantify energy savings from design strategies, compared to the incremental costs, can show where the biggest "bang for the buck" can be found.
