Commercial buildings have seen a drop in their energy intensity of more than 40% since 1980, according to a recent report from Bloomberg New Energy Finance and the Business Council for Sustainable Energy. Increased utility energy efficiency programs and higher efficiencystandardsare the main reasons. However, while primary energy is significantly lowered, overall electricity use is relatively flat. New gadgets like iPads, smartphones, and laptops are taking up the efficiency gains made in other areas.

Energy Analysis No Longer a Luxury
Back in the halcyon days of 2006, energy analysis of building design and performance was a luxury. Sure, many forward-thinking AEC firms ran their designs through services such as Autodesk’s Green Building Studio and IES’s Virtual Environment, and some facility managers used Honeywell’s Energy Manager and other monitoring software. Today, however, knowing exactly how much energy your building will produce and use is survival of the fittest as energy costs and green design requirements demand precision.

Historic changes to commercial building energy codes drive energy efficiency, emissions reductions
Revisions to the commercial section of the 2012 International Energy Conservation Code (IECC) represent the largest single-step efficiency increase in the history of the national, model energy. The changes mean that new and renovated buildings constructed in jurisdictions that follow the 2012 IECC will use 30% less energy than those built to current standards.
