Here is Your Elevator Pitch Against “LEED Equivalent” Projects

Originally published on December 6, 2016 by BNP Media through the Building Enclosure Blog. Have you ever been asked to design or construct a project “to LEED’s standard” without actually submitting for certification? This can initially sound like an attractive idea to a client. After all, as long as the owner knows the project is aligned with LEED, why pay the funds to get a plaque on the wall?   Lack of Accountability with LEED Equivalent The problem is, an….

Something special happens when….

Is acoustical comfort a green building issue?

Originally published on September 12, 2013 by IDO Incorporated. The term indoor environmental quality (IEQ) is very broad in scope. The design and construction profession commonly lumps four key topics under this umbrella terms: 1. Indoor air quality: To ensure that occupiable indoor air volumes are relatively free of contaminants and do not threaten human health or building damage functions. 2. Thermal comfort: To ensure that indoor environments can be properly managed to achieve and maintain rates of ambient air temperature,….

Evaluating Human Thermal Comfort

In building design and construction, energy efficiency does not necessarily equate to good thermal comfort for occupants. In fact, human thermal comfort is rather difficult to analyze because it is as much psychological as it is physiological. The notion of “comfort” is a personal feeling – not a quantifiable metric like the kilowatt-hour is for electricity. Think about it – who has not been in a room where one person claims to be uncomfortably hot while someone close by exclaims to be cold? So, how….

Navigating the “Red Lists”

It has been 50 years since Rachel Carson published Silent Spring. I recently took the time to read Carson’s seminal work (available through iTunes here), which outlines the environmental and human health costs of using pesticides, insecticides, and other chemical applications, and was struck by the relevance of the message. The green building movement is approaching a crossroads with the building product industry. A vast range of materials ranging from polyvinyl chloride (PVC) based products, to mercury thermometers, lead solders and roofing materials, and certain….
