A new prerequisite in LEED v4 calls for each project to measure whole building energy use, and then share that data with USGBC. Other key changes in the latest version of LEED include:
• Two new prerequisites for building-level water metering and outdoor water use reduction.
• Demand response credit requires that the demand response system must be capable of being fully automated, but can be operated in a semi-automated way.
• Renewable energy production credit increases the number of points available for renewable energy.
• Advanced energy metering prerequisite requires a permanent metering system that records intervals of one hour or less, and the meter must transmit that data to a remote location.
• Under the new Building Product Disclosure and Optimization credit, LEED v4 awards points for construction projects that use at least 20 building products that have issued Environmental Product Declarations or Health Product Declarations.

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.

Vancouver’s former Olympic Village shoots for Gold
The first tenants of the Millennium Water development in Vancouver, B.C., were Olympic athletes competing in the 2010 Winter Games. Now the former Olympic Village, located on a 17-acre brownfield site, is being transformed into a residential neighborhood targeting LEED ND Gold. The buildings are expected to consume 30-70% less energy than comparable structures.
