Learn how to find products for LEED and WELL projects in this webinar.
Are you struggling to find products for your LEED or WELL project? We’ve been there, and we know how to help.
In this hour-long free webinar, BuildingGreen's Nadav Malin and our partner Anne Hicks Harney of Long Green Specs share their tips finding green, healthy products that meet the requirements for LEED and WELL.
Can we put to bed the corrosion concerns with this insulation?
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:
Reducing your building’s carbon footprint or health impacts? Going after new LEED credits? Transparency documents for steel studs can help.
Editor’s note: Guest blogger Anne Hicks Harney, of Long Green Specs, is our partner in providing product vetting services. Harney offers guidance on writing green specs and on finding products for LEED v4, WELL, and beyond.
Mean radiant temperature, a major component of thermal comfort, is easy to measure.
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.
No man is an island, and neither is a building.
UGL Drylok Extreme, Koster NB1 Grey, Xypex Concentrate: Do these interior waterproofing systems really work?
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.
BuildingGreen’s president, Nadav Malin, recently received the Honorary AIA designation. The American Institute of Architects (AIA) “recognizes the notable contributions and service of people outside of the architecture profession with honorary membership in the Institute,” according to its website.
Paula Melton and Peter Yost discuss their process of writing a feature article about building failure.
Why and how do buildings fail? In this quick video, Paula Melton and Peter Yost discuss what they learned in the process of writing their feature article “How Buildings Fail Their Users.” The article includes seven stories of building failure and lessons learned. Read the feature article.
“We don't just do cellulose; we do it better.”
At the end of my recent blog post on Kooltherm rigid phenolic foam insulation, I mentioned that the roof and wall assemblies at an energy retrofit project in Brattleboro, Vermont, were insulated with cellulose by a company called American Installations.
How can firms develop sustainability knowledge that leads to action? Here are three places to start.
A deep-energy-retrofit project uses Kooltherm as part of a high-performance attic insulation system
Improving the thermal performance of an existing attic is often challenging: workers are faced with narrow cavities, low clearances, and cladding systems that make it hard to achieve desired R-values while still maintaining the necessary drying potential of the assembly. The house at 81 Chapin Street in Brattleboro, Vermont, is no exception. It’s a 100-year-old wood-framed two-story home that Candace Pearson and Alex Beck are determined to comprehensively retrofit to high performance.
How Yale University's energy manager uses after-hours walk-throughs to save energy
Julie Paquette has been Director of Energy Management at Yale University for about 6 years. That means the buck stops at Paquette’s desk for the energy consumption of over 400 buildings on campus. Yale has a pretty sophisticated approach to energy, including the Yale Facilities Energy Explorer, an energy dashboard system that shows energy consumption and details for every one of those 400 Yale buildings.
Simple ways to measure moisture content deeper into building assemblies
Typical pins on moisture meters are ½ inch long, meaning you can only determine moisture content by weight near the surface of building assemblies and materials (including wood, gypsum wallboard, and concrete). But I often find myself needing to assess moisture content of first condensing surfaces in walls and ceilings or well below the surface of basement slabs. This article looks at ways to extend the reach of a moisture meter. (For introductory information on moisture meters, see Tools of the Trade: Moisture Meters.)
Managing the high GWP refrigerants used in refrigeration and HVAC systems is one of our most pressing climate challenges. November’s BuildingGreen Report feature article explains why.
Paul Hawken’s book Drawdown looks at a number of strategies that would “reverse the buildup of atmospheric carbon within thirty years.” Based on careful analysis, his team concluded that the number-one action we can take to reverse anthropogenic global warming is to manage high global warming potential (GWP) refrigerants. Wait…what?!
How to use geological, soil, and historical maps to keep your basement dry
When we bought our home (built in 1907), I called in a favor from an electrician friend of mine to upgrade the 60-amp to a 100-amp service. Having worked together in New Hampshire where many of our projects were on sites full of ledge, he smirked when he told me: “Here, you go try and drive this 12-foot copper grounding rod!” No more than 10 minutes later I came in and said, “How much of the rod should remain above grade?”
