Energy Use Intensity (EUI) in Simple Terms

Originally published on August 17, 2017 by BNP Media through the Building Enclosure Blog.   Energy use intensity – or EUI. It has been called “the miles per gallon rating of the building industry,” but many design and construction professionals are not entirely sure how EUI is defined and what its utility is with regard to project. Below is a primer to help get anyone started.   Energy Use Intensity (EUI) Energy Use Intensity (EUI) can be defined as the….

When Will LEED v2.2 and 2009 Expire?

This column was updated on November 19, 2014 (it was first published on October 13th, 2013). Out with the old, in with the new. With the rollout of LEED v4 currently underway, LEED project teams should be mindful of the LEED-NC v2.2 and 2009 sunset dates. As every new version of LEED launches, USGBC initiates a process to phase out the previous version of the rating system. This process begins by establishing a date for closing registration. After the registration closure date,….

Using Renewable Energy in LEED v4

Energy efficiency is the starting point for any high-performance building. After reducing overall energy needs through building-related energy conservation measures, the next step is to invest in passive systems and high-efficiency HVAC systems. Smart controls can help a building operate even more efficiently. But in the end, there will always be a need to purchase or create energy for the building. On-site generation of renewable energy or the purchase of green power allows buildings to source the remaining energy needs without….

USGBC Announces “LEED Automation”

Two weeks ago at Greenbuild, USGBC made a very interesting announcement regarding an upcoming development to LEED Online. In collaboration with various leading technology companies, USGBC has developed a new program aimed at streamlining and creating capacity for the LEED building certification process. The program, referred to as “LEED Automation,” was explained as being similar to an app in the way it will serve project teams. According to USGBC, by integrating third-party applications with LEED Online, LEED Automation will serve….

Is LEED De-Certification One Step Closer to Reality?

Is LEED De-Certification One Step Closer to Reality?

With the rollout of LEED version 3 came the LEED 2009 Minimum Program Requirements. MPR #6 requires that “all certified project must commit to sharing with USGBC and/or GBCI all available actual whole-project energy and water usage data for a period of at least 5 year.” This, of course, led to a lot of speculation that USGBC would use the reported performance data to validated (or nullify) LEED certification. However USGBC has always maintained the clear position that LEED certification….

How Performance Metrics Will Change LEED Forever

Since its inception, the LEED rating system has been criticized for its points-based approach to green building that focuses on design intent rather than actual building performance. In fact, in many circles, this was strongly considered to be a potential Achilles’ heel of the blossoming rating system. Case in point: about two and half years ago, the New Buildings Institute (NBI) published a study that now appears to have been a watershed moment in the green building movement. In that….

On April 29th, USGBC officially launched the latest version of the LEED Rating System. More than eight years since its initial conception and three years following the launch of its pilot program, LEED for Neighborhood Development (or LEED-ND) is finally introduced. The rating system, which USGBC claims is the first national system for neighborhood design, integrates the principles of smart growth, urbanism and green building. The following is a quick primer for those who are unfamiliar with the new system…..

The LEED 2009 “Size Gap”

For any project to be eligible for LEED certification, it must meet the minimum program requirements (MRP) as approved by the U.S. Green Building Council’s LEED Steering Committee (LSC). The MPR can be accessed at: http://www.usgbc.org/ShowFile.aspx?DocumentID=6715 According to the MPR, new additions to existing buildings may be certified separately and independently from the existing buildings to which they are adjoined, provided that they are physically distinct and each has a unique address or name. Similarly, the existing structure can be….
