Typical Home Energy Problems – Building Science Issues Identified

Most homes built to code minimum standards (the worst possible home you can build by law) are energy hogs. This home is no exception.

Energy problemsDoing an energy audit and using a thermal image camera, you can immediately see there are problems. The band board in the basement is glowing, showing a huge thermal bridge to the outside. This is often an area lacking proper air sealing and insulation in this type of home. It does not cost more to get this right, it just takes time and education for your builder.

 

 

Energy auditThere are many more issues found from missing insulation to leaking duct work. Here you see air leaking from an interior wall showing a lack of proper air sealing in the attic.

Energy auditAvoiding these common issues is not hard. Having the proper specification included in your initial design will stress the importance to your builder of energy efficiency goals.

Snow Storm Coming? Clean Out Your HVAC Unit For Max Efficiency

Remember when you are clearing your driveway from a snow storm to also remove the snow from your outdoor units.

Snow, ice, and leaves can pile up around your outdoor heat pump which could drastically reduce the efficiency of the unit. The outdoor unit may also not be able to defrost as intended shortening the lifespan of the unit. Read more here to see how the snow can help you be more efficient. Have fun shoveling!

Green Term Defined: Vegetated Roof

Green Term Defined: Vegetated Roof

A green roof, living roof, or vegetated roof are all terms used to describe a partially or completely covered roof with vegetation over a waterproof membrane. There are two types of vegetated roofs, intensive or extensive. The difference is simply the depth of the planting medium.

The traditional vegetated roof uses larger plants and a deeper soil to support the root growth. Newer technology has allowed for a lighter planting medium that supports sedum plantings, but would not work for larger plants.

Vegetative roofs are not a new concept, having been developed originally in Germany in the 1960s. They have become more popular with the benefits of  added insulation, reduced storm-water runoff, habitat creation, and protection of roof membranes.  Vegetative roofs also benefit the reduction of heat island impacts in the urban setting.

Design flaws identified in this speculative home

Thanks for all your comments about the design flaws in the below images. You guys hit all the high points. The biggest is accessibility for sure. A door handle that can be opened with an elbow as well as a hand offers more flexibility for those of any ability. If you have your hands full or if you have bad arthritis you can still operate the door.

DSC08025Certainly the builder grade brass hardware is not going to last and is already out of “style.” This hardware will look worn in a matter of years and will most likely not hold up as far as durability is concerned. Spending a little more on quality up front will reduce your overall maintenance costs on any project.

DSC08008Having the door open so close to the corner will make it very difficult to use for someone in a wheelchair. It also greatly limits the flexibility of furniture layouts in this space.

DSC08036No deadbolt in the front door leaves a bit to be desired where security is concerned.

Also, there is no screen door on either the front door or back door so there is little chance to open up and air out the house on a nice day.
