We need to eliminate toxic fossil fuels from our buildings. This joint letter to HVAC equipment manufacturers asks them to address the gaps in the equipment that’s currently available.

Have you been moving toward electrifying HVAC systems but struggling to find the equipment you need?

The SDL Show-and-Tell session is where Greenbuild becomes more personal, more intimate, less business-to-business, and more community-centric.

by Daniel Overbey

The Greenbuild International Conference and Expo is the world’s largest conference and expo centered around sustainable design. Greenbuild is unparalleled in its robust educational and networking opportunities, but it can also be a bit overwhelming.

Can buildings be both comfortable and energy efficient? The Kendeda Building shows how the two can go hand in hand.

By Alissa Kingsley

User control may seem antithetical to high-performance buildings: imagine the amount of energy that might be wasted when building occupants are able to adjust the thermostat or open and close windows at will.

Selecting the greenest products doesn’t do any good unless strong specifications support your choices. Here’s some language you can use.

For real this time?

by Peter Yost

For twenty years or so, companies like Pilkington (Spacia) have been cranking out R-5ish (center-of-glass) vacuum-insulated glazing (VIG).

The carbon that’s emitted when we produce materials and construct our buildings is finally getting the attention it deserves.

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

by Peter Yost

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.

Can we put to bed the corrosion concerns with this insulation?

by Peter Yost

A particularly well thought-out and thorough question from reader Aaron Birkland on the pH of phenolic foam and its possible corrosive nature prompted me to follow up my original blog post on Kingspan’s Kooltherm rigid insulation. Aaron has two main questions:

Mean radiant temperature, a major component of thermal comfort, is easy to measure.

by Peter Yost

All the way back in 1993, one of my first research projects at the NAHB Research Center—now Home Innovation Research Labs—was assessing the performance of radiant ceiling panels for the Department of Energy’s Advanced Housing Technology Program. (The final report was titled “An Evaluation of Thermal Comfort and Energy Consumption for the Enerjoy Radiant Panel Heating System.”)

Buildings need renewables—but we need to look beyond the site.

UGL Drylok Extreme, Koster NB1 Grey, Xypex Concentrate: Do these interior waterproofing systems really work?

by Peter Yost

Back in May 2017, I wrote a blog post about negative side waterproofing (NSW). But I was still feeling troubled. The standardized test for NSW from the U.S. Army Corps of Engineers (“Standard Test Method for Water Permeability of Concrete”) is really complicated; the schematic seems impossible to decipher (see Image #1 in the slideshow). Instead of using this test, could we do a real-world, Wingnut-style test for negative-side waterproofing?

We sat down with BuildingGreen president Nadav Malin to discuss his Honorary AIA designation.
