Greener by Design: Exploring options with ecological roofing


With New York City’s 80×50 initiative to reduce greenhouse gas (GHG) emissions 80 percent by 2050, the stakes are high for the city to adopt progressively more stringent energy codes. Similarly, the Sustainable DC Plan professes the lofty goal of making the nation’s capital “the greenest, healthiest, and most livable city in the nation.”

Lighting accounts for about 10 percent of the country’s energy usage, according to the U.S. Energy Information Administration (EIA). Choosing the right lighting system is crucial when it comes to saving energy and reducing the carbon footprint of a building or campus. Thus, there has been a shift in developing technology that can integrate into the infrastructure of both ‘smart buildings’ and ‘smart cities.’

Comparing Polystyrenes: Looking at the differences between EPS and XPS


Insulation is a critical component to specify when designing a functional, cost-effective, and energy-efficient building. One method to insulate a building is by installing 50 to 152 mm (2 to 6 in.) of rigid foam insulation on the exterior side of the wall framing. Two of the most frequently installed types of rigid foam insulation are expanded and extruded polystyrene (EPS and XPS).

Buildings are a combination of design and construction. On paper, it may all seem to flow and make sense, but a small change in the former can have major impacts on the latter. Similarly, alterations that happen during the construction phase can end up causing significant design problems, affecting everything from acoustics to ambient noise.

Thermal efficiency in glazed curtain wall systems

Curtain Wall Feature Image

With glazed façades dominating urban landscapes, the strides made to improve the energy efficiency of glass are well-documented and generally well-understood. However, much more quietly, the framing members of wall and window systems have also been re-engineered. The performance improvements in these less-discussed components are poised to add up to big gains in efficiency.
