Overcoming Obstacles to Advanced Air Sealing
We all know the basics of energy efficiency. Air seal high in the building, then low, then insulate. Seems simple, right? Stop the air from leaking into or out of the building. Save money. Increase ...
Using hemp as an insulator might seem far-fetched. Laughable even. But this green sustainable material just might be the answer to many builders’ problems. Here’s why you should give it a chance. [continue reading]
This past February I received the following e-mail: Hi, Guys, We've had trouble with water spots on the ceiling since late last fall, and our builder tells us it's the result of melting snow—... [continue reading]
An important factor in the airtightness of a building, and its energy efficiency, is the amount of infiltration allowed through closed windows and doors. Typical old double-hung windows are especially prone to infiltration. [continue reading]
A reflective-insulation system consists of a low-e surface, like aluminum, which is installed facing an enclosed air space. Enclosed air typically has an R-value of about R-1 per inch, but by reducing the radiant-heat transfer ... [continue reading]
The idea behind venting to remove moisture is to allow it to escape out. Unfortunately in humid climates, it's much more complicated. [continue reading]
It is virtually impossible to achieve the standards of the 2009 International Energy Conservation Code (IECC) by accident, let alone those of the 2012 IECC, which is even more stringent. The 2012 IECC reaches into almost every part ... [continue reading]
Next Thursday, ACEEE will release the 2019 City Clean Energy Scorecard, our most robust report ever to track city progress toward ...
So, you want to build a backyard wind turbine and save hundreds every year? Well, you’ve come to ...
