Is Daylight Saving Time Necessary?

Originally published on March 7, 2016 by BNP Media through the Architectural Roofing & Waterproofing Blog. Spring Forward, Fall Back. We know the routine well, but have you ever wondered why the United States uses Daylight Saving Time (DST)? If you ask around, you’ll hear some interesting theories: …so kids don’t have to catch the school bus in the dark?      No. …to save energy?      Not really. …to benefit farmers by giving them an extra hour of daylight?….

Examining the Jevons Paradox through Residential Energy Consumption

Originally published on August 13, 2015 by BNP Media through the Walls & Ceilings Blog. Is there any such thing as a ‘perfect’ energy code? I recently posed this question to a colleague of mine – a gentleman with whom I have served alongside in multiple state code review committees over the years. He poignantly offered, “While new energy codes may improve the energy efficiency of a building, it does not follow axiomatically that the building will use less energy.”….

Creating U.S. Climate Data

  A cornerstone of design performance and energy modeling is access to relevant climate data. Climate data is the basis for the climatological conditions a structure will be subjected to during a computational analysis. Intuitively, we understand the broadly generalized differences between locations like Phoenix versus Minneapolis. However, a computer program needs more than intuition, it needs data.   Climate data defined In the most simple terms, the climate data files accessed by energy modeling programs contain annual, monthly, daily, and even….

The CBECS and Why It’s Important

Image courtesy of EDC magazine After years of financial setbacks, the Department of Energy’s national sample survey of commercial building energy use commences. Originally published in the April 2013 issue of Environmental Design + Construction (EDC) magazine. April marks an important milestone for the high-performance building community. After years of setbacks and complications stemming from financial strife, the U.S. Department of Energy’s 2012 Commercial Buildings Energy Consumption Survey (CBECS) will begin fielding data. It has been 10 years since the….
