Comparing Solar Heat Gain Coefficients (SHGC) and Shading Coefficients (SC)

Originally published on May 18, 2015 by BNP Media through the Walls & Ceilings Blog. I was recently discussing glazing properties with a mechanical engineer for an energy model of a corporate headquarters we are working on. We discussed U-factors first and then moved on to shading properties. We had this awkward moment where he asked me what the shading coefficients were. “You mean the solar heat gain coefficients?” “No, the shading coefficients,” he responded. This caught me off guard…..

Basics of Bulk Water Management through Rainscreens

Originally published on April 22, 2015 by BNP Media through the Walls & Ceilings Blog. The building envelope must face a number of damage functions: bulk and capillary water, air-born water, vapor, radiation (ultraviolet degradation), pests, and people. But even in dry climates, water in all its forms perhaps poses the greatest challenge to building performance and longevity – and bulk water is public enemy number one. In general, there are four basic approaches to bulk water management in a….

Preserving an Icon: The Indiana State Fair Coliseum

Opened to great fanfare in 1939, the Pepsi Coliseum was the premier public assembly venue in the state of Indiana for decades. It has hosted countless events for more than 70 years, including the only performances ever held in Indiana by the Beatles. While the past seven decades have given the Coliseum a rich and diverse history, they have also seen the facility descend into a state of disrepair and unable to meet the demands of a sports and entertainment….

Efficiency: Toward Net-Zero Energy (VoiceThread Presentation)

  Four years ago, I co-authored a white paper with my colleague Nick Worden at Browning Day Mullins Dierdorf (BDMD) Architects and William Brown, currently the Director of Sustainability at Indiana University. The white paper was published at 2010 International High Performance Buildings Conference at Purdue University and it presented a full-year of energy consumption and on-site renewable energy production data for the Chrisney Library (a branch of the Lincoln Heritage Public Library), verifying the project as the first non-residential net-zero (site) energy facility in Indiana….

What’s the Difference Between Insulation and Thermal Mass?

I just wrapped up an amazing first session of online instruction for a building envelope course at The Boston Architectural College’s Sustainable Design Institute. It was a very rewarding experience as I had the pleasure of interacting with a deeply knowledgeable international group of students at an advanced level on a very complicated topic. Among other observations, over the course of the session it became clear to me that there is a prevalent misunderstanding about the fundamental differences between “insulation” and “thermally massive”….
