The Difference Between Reflectance and Emittance

The Difference Between Reflectance and Emittance

Originally published on November 18, 2015 by BNP Media through the Architectural Roofing & Waterproofing Blog. What is emittance? Among the three basic forms of heat transfer – conduction, convection, and radiation – the term emittance refers to a material’s ability to release heat through radiation. The term necessarily refers to the heat exchange at surface of a material because heat exchange through a solid would be conductive and heat exchange through a fluid would be convective. Emittance is the….

Corporate Sustainability Reports (CSRs) and LEED v4

Originally published on October 20, 2015 by BNP Media through the Architectural Roofing & Waterproofing Blog. While various transparency labels such as Environmental Product Declarations (EPDs), Health Product Declarations (HPDs), and Cradle to Cradle Certified Products have received a great deal of attention under LEED v4, project teams can also be rewarded by choosing products from manufacturers that have publicly released information from their raw materials suppliers indicating extraction locations, a long-term commitment to ecologically responsible land use, efforts to….

When Will LEED v2.2 and 2009 Expire?

This column was updated on November 19, 2014 (it was first published on October 13th, 2013). Out with the old, in with the new. With the rollout of LEED v4 currently underway, LEED project teams should be mindful of the LEED-NC v2.2 and 2009 sunset dates. As every new version of LEED launches, USGBC initiates a process to phase out the previous version of the rating system. This process begins by establishing a date for closing registration. After the registration closure date,….

2014 INASLA Merit Award – Jacobs School of Music

The East Studio Building project for the internationally acclaimed Jacobs School of Music at Indiana University is a new facility that accommodates faculty teaching studios, as well as music practice rooms, classrooms, and rehearsal rooms. Browning Day extensively developed the surrounding site to accommodate a vehicular environment within a pedestrian setting. Our design created a corner plaza that serves both as a campus space and an arts district gateway at a major entrance to campus, while effectively dealing with accessibility….

Every Energy Model Is Wrong – And Here Is Why They Are Indispensable

LEED has taken some heat for buildings that do not perform as they were modeled, yet energy modeling is an essential tool for any high-performance building project. Originally published in the August 2014 issue of Environmental Design + Construction (EDC) magazine. Recently, LEED has come under fire for accounts of certified buildings not performing as well as their energy models predicted. Frequently mentioned amongst the antagonistic “gotcha” coverage is an out-of-context 2007 quote by the USGBC Research Committee acknowledging: “Buildings….

Using Renewable Energy in LEED v4

Energy efficiency is the starting point for any high-performance building. After reducing overall energy needs through building-related energy conservation measures, the next step is to invest in passive systems and high-efficiency HVAC systems. Smart controls can help a building operate even more efficiently. But in the end, there will always be a need to purchase or create energy for the building. On-site generation of renewable energy or the purchase of green power allows buildings to source the remaining energy needs without….

Localizing LEED

In search of greater responsiveness to local priorities, the process for identifying Regional Priority Credits is recalibrated for LEED v4. Originally published in the November 2013 issue of Environmental Design + Construction (EDC) magazine. One common criticism of LEED has always been the notion of taking a “one-size-fits-all” rating system and applying it to the entire building sector. If all sustainability is local, then surely LEED needed to respond to geographically distinct regional priority issues. LEED 2009 addressed this criticism….

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,….

Passive Agressive

It’s been 40 years since the 1973 Oil Crisis thrust the United States to the forefront of passive solar heating. But have technologically advanced building systems rendered passive strategies obsolete? Originally published in the August 2013 issue of Environmental Design + Construction (EDC) magazine. LEED v4 for Homes contains a three-point credit for optimizing a building’s orientation for passive solar heating. Details of the credit are specific to managing the amount, shading and orientation of south-facing glass. These are sound….

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….
