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….

Indiana’s First Net Zero Energy Building Certification is ‘Revealed’

For over half a decade, the Chrisney Branch of the Lincoln Heritage Public Library has touted its intent of producing more electricity than it consumes (a term known as “Net Zero Energy”). However, it has always been difficult to substantiate the claim with stakeholders, patrons, and the general public. In order to reaffirm its commitment to environmental stewardship, Lincoln Heritage Public Library sought to formalize its claim that the Chrisney Branch is the first net-zero energy building in the State….

Gauging the Seasonal Efficiency of Air-Source Heat Pumps

Originally published on February 23, 2015 by BNP Media through the Walls & Ceilings Blog. Recently, I was working on an energy model for a high-performance housing prototype. Mostly, I apply energy modeling to non-residential structures. I did not have a coefficient of performance (COP) at my fingertips for the air-source heat pump (ASHP) used in my baseline model. In this context, the COP is the ratio of the amount of thermal energy (heat) delivered by a heat pump to….

Toward Net-Zero Energy

While ongoing development of codes, legislation. and green building rating systems continue to raise the ante on the market’s expectations for high-performance building projects, net-zero energy buildings still remain elusive – especially in the private sector. There are several reasons for this, but the primary hurdle is the economic viability of systems for on-site renewable energy production (e.g. solar panels, on-site wind turbines, and so on). To explain the current economics of solar panels in terms that I feel are….
