BIM is the process of building a 3D data-rich model of all architectural, structural, mechanical and electrical systems in the building. The model is not only used to design the building and document it for construction, it's also used as the primary tool to create and coordinate design solutions.

Supermarkets, grocery stores and convenience stores have the second highest energy consumption of major building types in California, with electricity representing over 80% of this, and with energy-intensive refrigeration consuming the greatest fraction of electricity.

On a sunny summer day, a typical roof surface can reach temperatures that are nearly 100°F above the ambient temperature. A cool roof, by contrast, stays at or near the ambient temperature due to the characteristics of its outer layer.

HomeBase made a commitment to daylighting during a recent major remodeling campaign. Today, all 83 of this company's home improvement warehouse stores use extensive skylights and photocontrols.

Using the integrated energy design approach, designers can cost-effectively lower building operating costs while improving workers' comfort and boosting productivity.

There's been a big explosion in big box retail buildings: In 1970, there were an estimated five square feet of retail space for each person in the U.S. By 2000,that figure had risen to 20 square feet per capita. Since the large retail (greater than 10,000 square feet) segment is the second greatest energy user of all commercial segments, the implications of this growth trend are significant.

Not all energy-efficiency measures are appropriate for all building types, but some are especially useful for particular buildings. This Design Brief reminds designers and builders of opportunities they should consider in each of their projects.

A few building simulation runs early in a project can lead to design solutions that, though they appear simple, significantly improve building energy performance.
