Applets for Energy and Environmental Design

Originally published on July 10, 2017 by BNP Media through the Building Enclosure Blog. Newsflash: There are a lot of great (and free) online resources for design professionals. When I am having exchanges about energy and environmental design analysis with colleagues and students, it seems like I am constantly referring them to any number of small, accessible online utility programs for performing simple – yet highly sophisticated – functions. Some would refer to these small programs as applets. Below, I have….

Lighting Impacts on Circadian Rhythms

Originally published on July 11, 2016 by BNP Media through the Architectural Roofing & Waterproofing Blog. With the emergence of human health concerns, wellness, and biophilia as priorities in the building design and construction industry, the lighting profession is shifting its focus toward circadian lighting design. Light is one of the main drivers of circadian rhythms – that is, our internal clock that keeps the body’s hormones and bodily processes on a diurnal cycle, even in continuous darkness. When the….

Five Ecotect Functions that Need to Be Migrated to Revit

Originally published on May 18, 2016 by BNP Media through the Architectural Roofing & Waterproofing Blog. Eight years ago, Autodesk made a bold and decisive move toward prioritizing sustainable design tools when it acquired the assets of Square One Research, including their design performance modeling software Ecotect. To that point in time, Dr. Andrew Marsh had incrementally built the Ecotect platform into a light, versatile energy analysis tool. Its playful graphic outputs and high degree of interoperability made it a….

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….

Methodologies for Glare Analysis

Methodologies for Glare Analysis

Any complete analysis of a daylit interior environment should include both the amount of light arriving to specified surfaces (such as work planes) as well as an assessment of the visual comfort of the space. Both of these factors are dynamic. Thus, they will change throughout any given time period (e.g., hour, day, week, month, season). The former can be quantified in a rather straightforward sense because it’s just physics. There is a specific amount of lumens entering a space and the characteristics of….
