The Energy Audit – Step One  in the Renovation Recipe

If you are reading this, you have probably already done things like switched out your incandescent bulbs with compact florescent, plugged your TV and its 500 peripheral toys into power strips, turned up or down your programmable thermostats, and made some other basic energy saving changes in your home. We will focus on some of those basic things in future articles, but for now we will take things to a different level.

Put simply, every homeowner should consider having an energy audit. This is especially important if you are considering an addition or renovation and might have access to the inside or outside of walls, ceilings, or ducts (including residing or reroofing projects) to be able to plug leaks or add more insulation.  An audit will give you the information you need to begin to turn your 1950’s Swiss cheese box into a highly efficient machine. The result should be a report that gives you specific information about where you are losing energy in your house and what actions you can take to reduce the loss.

I have to admit that energy audits were not on my radar when I began planning my addition 7 years ago. I did not have an audit performed for my house until after my renovation work was completed, when I realized it was too late to seal up some of the exterior walls of the existing part of my home. Lessons learned.

Even if you are not considering an addition or other major home improvement, an energy audit will still offer you a road-map guiding you along a series of useful energy saving improvements throughout your home.

Top 5 Things to Do or Consider Before You Start Home Renovations:

1.  Have a full Energy Audit Performed by a RESNET or BPI certified auditor who seems to know what they are doing – getting references is also a good idea.

2. Think about any walls or ceilings that you might be able to get into to make more airtight or add more insulation to during the renovation.

3.  Hire a good insulation company to make the insulation and air sealing improvements, unless you feel confident that your general contractor has experience doing this type of work (this is not too common).

4.  If replacing appliances or heating and cooling systems, choose only Energy Star rated equipment or those with equivalent energy usage.

5.  If you are married or live with a significant other, pre-order some relationship counseling for the stress that will inevitably be created in living through a renovation together.

Adventures of a Home Energy Nerd- an Arlington Based Contribution.

Preamble: I am a total energy conservation nerd on top of being a geek about pretty much anything having to do with the environment. I have not given myself this title of “energy nerd”, but rather it has been lovingly bestowed upon me by my two children who are nearing and beginning their teen years (go figure), and by my husband. I am sure my two dogs would call me that as well if they could talk, but they do give me the same type of glazed over looks when I start talking about energy stuff, so I know they are thinking it. With that being said, I am lucky enough to have a family who has allowed me to use our humble home as an awesome laboratory in which to create endless amounts of chaos and mess, and to spend endless amounts of time and money in order to learn more about sustainable building, and of course for the ultimate quest- to save energy!

I started getting really interested in green building and home energy savings when I was planning an addition to our very modest Arlington home about seven years ago. At that point in time, green building techniques were in their infancy in the D.C. area in terms of local product availability, the knowledge pool, etc… Needless to say, this made building an energy-efficient addition with some other green features quite a challenge. But, we slogged through it, managing to take a fairly leaky and uninsulated 1940’s cape code to a point where it was just on the border of being overly tight, then adding a mechanical ventilation system, replacing other systems, and ultimately adding modest sized solar electric and hot water systems. Through this addition and a number of other home renovations and improvements, I have learned a great deal and hope to share with you over the coming months some of this knowledge, our successes and failures, lessons learned, and some rather humorous stories along the way. I hope you enjoy them!
