St. Louis Attic Insulation
Lack of attic insulation can be noticed in our excessive energy expenses throughout each season. Attic insulation is one of the most cost effective ways to minimize these expenses.
Blown cellulose attic insulation typically results in a 25-40% savings in our utility bills each month. Green Space Construction is a leading installer of blown cellulose attic insulation.

How to Seal HVAC Ductwork
The best solution for ensuring a proper seal and energy efficiency is to apply mastic and tape to every joint in the ductwork. The first step is to make sure the joint is clean and has been wiped down. This will allow the mastic to adhere properly and create a tight seal. You then want to apply a generous portion of mastic to coat the entire duct surface over the joint. You can use a brush or trowel to spread the mastic on. Then work the mastic into the joint, pressing and spreading lightly to achieve an even coat. You should strive to achieve a 1" overlap beyond the joint.
Then apply a mesh tape to reinforce the mastic. It's critical to make sure the mesh being used is designed for the brand of mastic used, so don't forget that!
By making these simple improvements to your home's ductwork, you'll save energy from day one and improve the comfort in your home! If you'd like help with this, we'd be happy to offer an analysis and estimate for your home's energy needs.

Energy Efficiency Doesn't Have to be Expensive
When most people think about energy efficiency, they think about expensive window replacements or HVAC system upgrades. But the reality is that big improvements can be realized from smaller investments. Many homes can realize dramatic improvements in efficiency by focusing on sealing major air leaks, installing better insulation in the attic, and insulating pipes.
These improvements often require caulking, spray foam sealant, selective installation of rigid foam board insulation, weather stripping and attic insulation. The cost is often under $2,000 and can be recouped through energy savings in 5 to 10 years. And your home will be more comfortable on day one.
Upon close inspection, many homeowners find that they have been living in a very drafty home for years. Pipe and duct penetrations into the home and between unconditioned/conditioned spaces are a big culprit. Poorly sealed windows and doors, mailbox slots, attic access hatches, and other cracks/gaps are also typical areas where air infiltration occurs. Sealing these gaps is cost effective, and provides long term value.
In addition to these cost-effective improvements, installing new insulation in attic spaces can have a dramatic impact. Depending on your home's needs, we will recommend a range of thicknesses to achieve desired results. We also take time to seal various air leaks in the attic, and recommend insulation covers for your attic access.
Performing these minimal improvements can be expected to save you at least several hundred dollars per year on your utility bills, and in many cases much more.

Reasons to Insulate Your Home During the Summer
The number one benefit is keeping your conditioned, cooled air inside of your house. By bolstering your homes insulation, and performing selective air sealing and other weatherization practices, you effectively contain a maximum amount of your homes conditioned air.
Cool air can escape your home through drafty windows, doors, poorly insulated ducts, and other knooks and crannies in your home. Furthermore, a poorly insulated attic space will cause your top floors to be warmer as heat radiates through. These problems can not only be uncomfortable, but also cause your air conditioning system to run harder and longer. And the harder and longer your equipment is running, the higher your utility bills will be.
A properly insulated, sealed, and ventilated home will also take far less time to reach the optimal temperature in summer months. All of these are great reasons to consider assessing your home's needs sooner rather than later.

The Property Assessment Clean Energy Act (PACE)
Missouri's House of Representatives just passed the Property Assessment Clean Energy Act, known as PACE. So what does this mean for you and your home or commercial property?
Let's start with what the bill specifically provides for. The bill initially authorizes municipalities to establish "clean energy development boards" that will be charged with establishing "property assessed clean energy programs" within their communities. These programs will finance energy efficiency or renewable energy improvement projects. Interested property owners will have to apply to the board, to have their project financed through a special annual assessment levied against their property tax bill. The property owner will enter into a contract with the board, in order to gain financing for the cost of their project, and will require a lien against the property being assessed.
So, again, what does this mean for you? It means that you will be able to finance energy efficiency improvements to your home, over a 20 year term with annual payments made with your property taxes. The PACE program will finally make energy efficiency upgrades available to the masses. With 20-year financing available, homeowners can more than pay for the improvements with the savings created from lowered utility bills. Most weatherization and energy efficiency upgrades offer financial paybacks between 2 and 15 years, so you can see how powerful this program will be in saving Missouri residents money, lowering our energy usage, and creating more comfortable homes!
Let's look at an example for a homeowner with a 1,500 square foot house that currently pays $300 per month in heating and cooling bills. Let's assume that they have an energy audit conducted for $500, and subsequently invest in $4,000 of energy efficiency improvements. The total amount assessed and financed through PACE will be $4,500 over a time period of 20 years. Let's assume that the interest rate on this financing is 8%. Under this scenario, you would pay approximately $458 annually for twenty years.
For a typical house of this size, it could be reasonably expected that the improvements would yield 20% energy savings. In other words, this homeowner would save $60 per month or $720 per year on their energy bills. Comparing this with the cost of their financing, the homeowner would profit $262 annually. Not to mention living more comfortably and reducing their carbon footprint!
As more details become available on the specifics of the PACE program in Missouri and St. Louis, Green Space will keep you up to date. For more information on the PACE program, please visit www.pacenow.org.
