Seal Leaky Air Ducts from the Inside

Start-up Aeroseal has been getting decent media exposure lately with a writeup on Energy.gov and a listing on This Old House‘s Top 100 Best New Home Products of 2011.  The company has an exclusive license to technology originally developed within the Indoor Environment Program at the Energy Department’s Lawrence Berkeley National Laboratory.  In short, Aeroseal sends a sealing mist through air ducts to eliminate holes and cracks of up to 5/8th of an inch — resulting in improved comfort and energy savings.

The Colonoscopy of Energy Efficiency

Earlier this week, the Shelton Group released its seventh annual Energy Pulse report, which has 450 pages of analysis, charts, graphs, and crosstabs based on the survey of 1,502 Americans.  I haven’t seen the $5,000 report but would like to share some takeaways from a release and executive summary.  Particularly, of the respondents, 42% had installed high-efficiency windows, 39% had installed extra insulation, 37% had installed higher efficiency HVAC systems, and 24% had installed a higher efficiency water heater.

Illuminate and Insulate with CanCoverIt

David Hanacek of EcoCycle Solutions loves to think up practical, cost-effective building products that make a big impact on efficiency. Take his Flow-Thru Finisher for example, a handy little caulk gun attachment that helps get adhesive exactly where and how you want it.  Before that, it was a clog-free drain device and lightweight steel shipping pallets.  But it’s his new invention, the CanCoverIt, that gets him most excited.   After all, what looks like a ho-hum, odd-looking box is actually a breakthrough invention that can save countless kilowatts and millions of dollars for homeowners.

The average home spends more than $2,200 per year on energy bills and roughly half of this amount goes towards heating and cooling, according to the Department of Energy.  When a programmable thermostat is set and used properly, a homeowner can save about $180 annually.  But the problem is, virtually everyone with a programmable thermostat doesn’t set or use it properly.  Nest Labs, a Palo Alto-based start-up, aims to solve this problem with a new thermostat that’s simple, sleek, intuitive, and smart.

The EPA Upgrades DVR Efficiency Rules

A few months back, the New York Times put a spotlight on the obscene energy use of cable, DVR, and other set-top boxes.  There are 160 million set-top boxes in the US, according to the EPA, and these boxes annually consume about $3 billion in electricity.  What’s shocking is the fact that about 66% of this electricity is spent when no one is watching and no shows are being recorded.  In the home, the DOE estimates that two set-top boxes will use about 500 kWh of energy every year — more energy than it takes to run a new refrigerator!
