How the accumulation of dust, pollen, and bird droppings affects the energy production of a PV array

July 10, 2018

I was at my brother’s house in Lee, New Hampshire, recently and looked up to see that his photovoltaic (PV) panels looked a bit dull (see Image #2 in the slideshow). His PV array is easy to get to—the long north slope of his roof has a walkable 5:12 pitch—so we went up and took a closer look.

It turns out that the PV industry... Read more

The LightFair innovation award winners showcase LED lighting’s evolving technology and how its sustainability image has changed.

July 9, 2018

The most energy-efficient LED light is cold, blue, and focused directionally on a small area; it is some of the worst light quality imaginable. Yet in the early years of LEDs, energy efficiency, or efficacy (measured in lumens produced per watt consumed, lpw), was the prime metric for judging LED performance. The industry suffered through a... Read more

How can architects and designers increase social value in the built environment?

July 9, 2018

Buildings contribute to social sustainability by providing environments that support communities in meeting their social needs. It’s generally easy to understand how the design, construction, and operation of buildings affect the environment. A building’s energy use or carbon cost, for example, are objective and quantifiable. But the building’s... Read more

Aimed at improving building performance, a new standard offers comprehensive guidance on energy modeling during design.

July 2, 2018

Building energy modeling has become more common over the last decade or so, and it’s a standard practice for projects pursuing LEED certification. But there’s a problem: the later the team waits to start modeling the building, the more potential energy-saving opportunities have been missed along the way.

“Often building energy modeling... Read more
