In the past, if you had a problem with your house you would have to guess which trade to call depending on the nature of the problem.

For example, if a room won’t get warm, you might call a heating contractor.  They would likely sell you a larger furnace.  If you called an insulation contractor, you might get a bid for insulation.  If you called a window contractor, guess what?  New windows!

So which one would be right?  Maybe all.  Maybe none.  The problem is that by calling upon specific trades to solve problems you are setting yourself up to need whatever they happen to sell.

Specific trades are limited in the number of tools they have at their disposal to solve your needs.  And if the only tool they have is a hammer, your problem will likely look like a nail.

Home Green Home is one of a growing number of “Home Performance Contractors.” We are trained and certified to look at your home for what it is - a series of systems that need to work together in order to provide you with a healthy, comfortable, safe, durable and energy efficient home.

When you call upon Home Green Home, we perform a series of diagnostic tests based on principles of building science to arrive at recommendations that will meet your needs and solve your problems.

So why do you call us?  For honest answers and competent repairs that efficiently and effectively address your concerns.

The tool you are referring to is called a blower door and it is one of our primary tools for evaluating the air barrier of your home.

Simply put, the air barrier refers to the dividing line between conditioned and unconditioned air: everything on the inside of the air barrier is conditioned air, and everything else is unconditioned air. Movement of air through the air barrier is considered leakage. The amount of leakage has a huge impact on the energy efficiency of your home. Air leakage also degrades breathing air quality and depending on quantity and location can affect comfort, durability and safety of your home.

We use a blower door to figure out how leaky your house is.  The blower door is a powerful fan that exhausts air from your house.  This causes the air pressure inside your home to fall below the air pressure on the outside.  As a result, outside air pushes against the house and finds ways to leak in.

Our blower door with its companion measuring gauges and computer is able to quantify both the volume of air that leaks in and out of your home as well as the combined size (in square inches) of leakage area.

Then, using tools such as our thermal imaging camera and smoke pencils, we investigate areas all around your house to identify areas of leakage and to recommend how these leaks could be addressed.

By using advanced diagnostic procedures, Home Green Home is able to achieve remarkable energy savings and comfort benefits for your home.

Unfortunately, they are not so benign.

The reality is that in most homes, attic hatches are enormous wasters of energy.

They tend to fit loosely in openings that have not been designed or constructed with any thought towards energy efficiency.

The panels are lightweight, which causes them to not sit tightly even if an air-sealing gasket is present (which it normally isn’t).

In the photograph to the right, you can easily see visual proof of this energy loss in a typical home (this particular example is a 20 year old house in Town & Country).

Home Green Home performs this type of thermal photography during every initial assessment as a way of gathering objective information about your home.

Notice that the ceiling around the hatch is nice and cool as a result of proper insulation in the attic.

However, the hatch itself is more than ten degrees warmer than the house because it is uninsulated.

In the winter especially, this will represent a waste of energy because heated air that naturally rises will be lost to your attic requiring your furnace system to do extra work to replace it.

Home Green Home is happy to take care of this problem for you.  We would install an insulated hatch that seals tightly to prevent both air flow and heat loss.  This type of upgrade to your home will save energy, reduce energy bills, improve comfort and clean up your breathing air (by keeping the nasty attic air out of your house).

The photo to the left is a thermal image of an ordinary kitchen wall.

The dark blue box at the bottom of the photo is the top of the kitchen cabinets. The red is hot attic air running through the wall down to the basement.

The wall is enclosing a “vent chase” which is where the exhaust for the furnace and hot water heater run up and out of the house.

As is common in many homes, the vent chase was left open to the attic and the basement when the house was built.

It should have been sealed, but that was almost never done until a few years ago. Even today, it’s a detail that most builders miss.

The affect of this inattention to detail is a “wind tunnel” of super hot or cold attic air (dirty, too) that can be drawn into the house by the furnace. Other times, heated or cooled air can escape into the attic.

Either way, you lose conditioned air and must spend money to cool or heat the replacement air.

At Home Green Home, we see one of our major rolls as being a “house detective” to figure out how air is moving and how energy is wasted. We then recommend and install the required fixes resulting in reduced energy use, lower energy bills, cleaner breathing air and a greener house.

It is no secret that the services we provide save money.

Many customers report saving 20-30%, some even more than 40% off their home’s energy consumption for heating and cooling after having an energy audit and making the recommended improvements.

That’s pretty good (to say the least)!

But good has just gotten even better now that the Federal Government has annouced TAX CREDITS for Energy Efficiency Upgrades.

These credits apply to upgrading HVAC systems and windows.  Most important, you can get the credits for installing air sealing and additional insulation.  Learn about these new tax credits by clicking here.
