Good Drainage Planes stop Capillary Action

We use drainage gaps or planes in wall systems to stop water from entering the building shell and causing deterioration or mould. This air gap does two things if wide enough; it prevents water’s surface tension from staying or even climbing up the wall and the gap also disperses the forces of wind driven rain or solar vapour drive. Let’s look at…

CO in Attached Garages

On two separate Quality Assurance site visits in the past two weeks I've detected elevated levels of Carbon Monoxide (CO) coming from attached garages. I was a bit surprised at this since neither garage contained a car - let alone any active source of combustion. So I did some digging and came up with this great resource from Iowa State on the topic. From my reading of…

Learning Thermostat - a huge impact on Energy Savings

Ok, I have had a couple programmable thermostats in the past... But, once again about 11 months ago I was doing my weekly (sometimes daily) stroll through the neighborhood 'big-box' home improvement store and back in the back past the garden section there is this little…

Why do we have Sizing Limits?

There are not as many contractors out there as you would expect that are current with the most recent, and always updating, residential building code.  Particularly when it comes to the sizing limitations for HVAC equipment, most contractors consider this minimum requirement by law nothing more than a nuisance.  There is nothing more frustrating to see in a quality control role than a system that was sold, sized, and installed prior to the start of the system design process.  Completing a…

LED Lighting, 6-month update

Background

Ok, back in November 2012 I stumbled into my local 'big-box' home improvement store with an extra $1,000 USD to burn and without any research or pre-planning I purchased 35 LED bulbs to replace my incandescent and CFL bulbs. I was way tired of continually replacing a couple CFLs time and time again and the 25,000-50,000 hours of lifetime sparked my interest and put a $1K hole in my wallet. At a burn time average of 3-hours per day that is 22-45 years of…

Atlanta, Georgia has a reputation for getting pretty darn hot, but it can also get pretty dang cold (No snickering from you Northerners, please!). Believe it or not, Atlantans use more energy to heat their homes than they do to cool them. The design temperature set by …

Home Energy and the Fracking Dividend

Most of us will agree that it’s technically feasible to build homes that consume dramatically less energy than today’s typical home. And in most locations we can build a home that draws net zero energy from the utility. But it’s economics that makes us hesitate. Specifically, it’s the value of those energy savings. Can the additional investment be offset by anticipated reductions in energy costs? It’s the same thing for retrofits of existing homes: Do the lower energy bills justify the…
