Cash for Caulkers – The Definitive Guide To The Home Star Energy Retrofit Act of 2010 By: Houston Neal

“Cash for Caulkers” is nearly here. Last month the House of Representatives passed H.R. 5019 – also known as the Home Star Energy Retrofit Act of 2010 or “Cash for Caulkers” – to kick-start construction, create jobs and cut back carbon emissions. While the bill still needs to clear the Senate, supporters predict it will pass this summer.

This is great news for homeowners and contractors alike. The bill provisions $6 billion for energy-efficient or “green” retrofits. It is expected to fund renovations for 3 million families, create 168,000 new jobs and save consumers $9.2 billion on energy bills over the next 10 years.

But in order to cash in on upcoming rebates, homeowners and contractors will need to do their homework. There are 13 types of retrofits eligible for funding. Each retrofit has unique eligibility requirements and set rebate amounts. You can read the full text here.

We made it really easy to wade through the legalese. Below is a table that breaks down the 13 retrofits of the bill, along with the requirements and rebate amount for each. In addition to the requirements we listed, each retrofit must comply with Building Performance Institute (BPI) standards or other procedures to be approved by the Secretary of Energy.

Retrofit Requirements Rebate Amount
Air sealing Rebate covers both interior and exterior sealing and includes use of the following products: sealants, caulks, insulating foams, gaskets, weather-stripping, mastics, and other building materials. $1,500

Attic insulation Must meet the attic portions of the Department of Energy (DOE) or Environmental Protection Agency (EPA) thermal bypass checklist. You must add at least R–19 insulation to existing insulation, and it must result in at least R–38 insulation in DOE climate zones 1 through 4 and at least R–49 insulation in DOE climate zones 5 through 8. Finally, it must cover at least 100 percent of an accessible attic or 75 percent of the total conditioned footprint of the house.

We also decided to combine these retrofits into three packages that will help homeowners get the best bang for their buck. But first, let’s review the program details.

Who is Eligible and How to Qualify?
The Home Star bill offers two rebate programs, the “Silver Star” program and “Gold Star” program. Here are details for each:

Silver Star – Unless another amount is specified in the “Rebate Amount” column above, homeowners will receive a $1,000 rebate for each retrofit listed in our table. The maximum amount of rebates paid out will be $3,000 or 50% of the total cost, whichever is lower. For example, if a homeowner spends a total of $4,000 on eligible retrofits, they will get $2,000 or 50% back as a rebate. If they spend $8,000 on eligible retrofits, they would only receive $3,000 in rebates instead of $4,000 (which would be 50% of the cost).
Gold Star – To qualify for the Gold Star program, homeowners must reduce their total home energy consumption by 20%. A $3,000 rebate will be rewarded for this reduction. Homeowners can receive an additional $1,000 for each additional 5% reduction, up to a total rebate of $8,000 or 50% of the total retrofit cost. Rebates may be provided for any of the retrofits listed under the Silver Star program, or for any other energy-saving measure, including: home energy management systems, high-efficiency appliances, highly reflective roofing, awnings, canopies, and similar external fenestration (window) attachments, automatic boiler water temperature controllers, energy-efficient wood products, insulated vinyl siding, and mechanical air circulation and heat exchangers in a passive-solar home.
The Home Star bill also includes rebates for do-it-yourself (DIY) homeowners that are confident in taking on the renovations themselves. DIY’ers can get up to $250 in rebates for products purchased without installation service. This rebate is limited to attic insulation, crawl space insulation and/or air-sealing retrofits.

Seal Your House Envelope and Improve Insulation
Before carrying out any serious retrofit, homeowners need to weatherize and seal their house “envelope.” The envelope includes outer walls, windows, doors, floors and the ceiling. If the house is not properly sealed and insulated, then subsequent HVAC retrofits won’t be as effective.

Common Air Leaks
In some cases, savvy do-it-yourselfers may be able to handle these projects themselves. There are plenty of books and great online resources (e.g. ACEEE.org) that provide instructions. However, you should seriously consider hiring an auditor beforehand. Special diagnostics equipment will show where air is escaping and to what extent. For example, thermal imaging devices detect areas in walls that are poorly insulated and dispersing heat. This information would be unavailable without such devices.

So how much does it cost to seal all the air leaks in a home? Prices will obviously vary based on where you live, how big your property is and the scope of the retrofit. But it will likely cost a few thousand dollars to hire a contractor for this type of renovation. In this example from the New York Times, the author spent $3,760 for insulating and sealing the envelope of his 1,200 square foot home.

How much can homeowners expect to save? The Environmental Protection Agency (EPA) estimates that homeowners can save 20% on heating and cooling costs by sealing leaks and adding insulation. In New York – one of the most expensive places to heat a home with an average annual cost of $1,513 – this would be a yearly savings of $300 just for heating.

Continuing with the example from the New York Times, the Silver Star program would provide $1,880 (50%) in rebates for their retrofit. At an annual savings rate of $300, the renovation would pay for itself in six years (or less if you include cost savings from reduced air conditioning bills).

Repair and Replace Leaky Ducts
Ducts are notoriously leaky and inefficient. They are one of the usual suspects in a crime of high utility bills, or when rooms are difficult to heat and cool. The EPA calculates that 20% of air moving through ductwork is lost due to leaks, holes and poor connections. Other sources put estimates closer to 40%. So while suffering from “leaky ducts” may sound innocuous, it can have a big impact on the efficiency and costs of heating and cooling your home.

Fortunately, duct replacement and sealing is eligible for funding under the Home Star bill. Many homeowners will want to outsource this project to a qualified HVAC contractor. Contractors have equipment to detect leaks that otherwise may not be immediately visible. They also have methods to seal ducts that are inaccessible. For example, by spraying an adhesive or sealant through the duct work.

Replacing and sealing ducts can also be a DIY project, especially when ducts can be easily accessed in an attic or basement. Leaks should be sealed with mastic sealant or metal tape (not duct tape), then insulated to reduce heat loss and to further improve efficiency. The Lawrence Berkeley National Laboratory has an excellent guide on how to seal and insulate ducts.

Upgrade Your Furnace and Water Heater
Heating is the largest energy expense in homes, according to the American Council for an Energy-Efficient Economy (ACEEE). In colder parts of the country, it makes up 30 to 50% of annual energy bills. So improving the heating efficiency of your home will have the biggest impact on lowering your energy costs. Sealing air leaks is a good start, but replacing your heating system could provide real leverage towards cost savings.

If your furnace or boiler was purchased before 1990, then it is time to consider an upgrade. Modern furnaces are much more efficient than those that are older than 20 years. You can use rebates from the Home Star bill to replace your furnace, but you will need to meet their guidelines:

Type of Replacement Requirements Rebate Amount
Replacement with a natural gas or propane furnace The furnace must have an AFUE rating of 92 or greater; or an AFUE rating of 95 or greater. Must be installed in accordance with ANSI/ACCA Standard 5 QI-2007.
$750

Replacement with a natural gas or propane boiler
Boiler must have an AFUE rating of 90 or greater. Must be installed in accordance with ANSI/ACCA Standard 5 QI-2007. $1,000
Replacement with an oil furnace
Furnace must have an AFUE rating of 86 or greater and use an electrically commutated blower motor. Must be installed in accordance with ANSI/ACCA Standard 5 QI-2007.
$1,000
Replacement with an oil boiler
Boiler must have an AFUE rating of 86 or greater and temperature reset or thermal purge controls. Must be installed in accordance with ANSI/ACCA Standard 5 QI-2007.

$1,000
Replacement with a wood or pellet furnace, boiler, or stove
The new system must meet at least 75 percent of the heating demands of the home; and in the case of a wood stove, but not a pellet stove, replace an existing wood stove, but not a pellet stove, and is certified by the Administrator of the EPA. The home must have a distribution system (such as ducts, vents, blowers, or affixed fans) that allows heat to reach all or most parts of the home. In the case where an old wood stove is being replaced, a voucher must be provided by the installer or other responsible party certifying that the old wood stove has been removed and rendered inoperable or recycled at an appropriate recycling facility. An accredited independent laboratory recognized by the Administrator of the EPA must certify that the new system has thermal efficiency (lower heating value) of at least 75 percent for wood and pellet stoves, and at least 80 percent for furnaces and boilers; and has particulate emissions of less than 3.0 grams per hour for stoves, and less than 0.32 lbs/mmBTU for outdoor furnaces and boilers.
$500 for a wood or pellet stove that has a heating capacity of at least 28,000 Btu per hour. $1,000 if it provides 75% of the heating demands of the home.

Water heaters are typically the second largest energy users after home heating and cooling systems. Replacing convention oil-fired water heaters with high-efficiency gas or electric heaters can save homeowners thousands of dollars over a 10 to 15 year period. The Home Star bill includes a variety of replacement options eligible for rebates.

Replacement options Rebate Amount
Replace with a natural gas or propane condensing storage water heater with an energy factor of 0.80 or more, or a natural gas or propane storage or tankless water heater with thermal efficiency of 90 percent or more.
$1,000
Replace with a tankless natural gas or propane water heater with an energy factor of at least 0.82.
$750

Replace with a natural gas or propane storage water heater with an energy factor of at least 0.67.
$400

Replace with an indirect water heater with an insulated storage tank that has a storage capacity of at least 30 gallons and is insulated to at least R–16; and is installed in conjunction with a qualifying boiler described in the previous table.
$1,000
Replace with an electric water heater with an energy factor of 2.0 or more. $1,000
Replace with an electric tankless water heater with an energy factor or thermal efficiency, as applicable, of .96 or more or a thermal efficiency of 96 percent or more, that operates on not greater than 25 kilowatts.
$250 each for a maximum of 4 electric tankless water heaters

Replace with a solar hot water system that is certified by the Solar Rating and Certification Corporation or that meets technical standards established by the State of Hawaii.
$1,000
Replace with a water heater installed in conjunction with a qualifying geothermal heat pump – as described in our first table – that provides domestic water heating through the use of a desuperheater or year-round demand water heating capability. $500 for a desuperheater

Ground Source Heat Pump
An alternative to furnaces and boilers are ground source heat pumps (GSHPs). Also known as geothermal heat pumps, GSHPs are one of the most efficient systems for heating and cooling buildings. According to the International Ground Source Heat Pump Association, GSHPs are 50 to 70% more efficient than other heating systems, and 20 to 40% more efficient than traditional air conditioners. They can also be used as an alternative water-heating system and save up to 50% on water-heating bills.

Ground source heat pumps are more economical than using oil or air-source heat pumps, but there is still a lot of debate over GSHPs versus natural gas. Homeowners will need carry out their own due diligence beforehand. For starters, here is an academic report that compares the two options.

Year over year, a ground source heat pump is more cost effective than natural gas. It’s the initial cost that really drives down the return on investment (ROI) and makes natural gas a more attractive option. However, there are several rebates and tax credits available that help subsidize the upfront cost.

Additional Financing Resources
With other legislation in the queue, it might take weeks or months to hear the Senate’s final decision on the Home Star bill. In the meantime, homeowners can receive funding from other sources to pay for green renovations. The federal government, state governments, local municipalities and even utility companies offer several options.

For example, homeowners can still receive a federal tax credit for 30% of the cost of energy-efficient products (up to a total credit of $1,500). This includes the purchase of central air conditioning systems (both the product and installation), electric heat pumps, furnaces and boilers, and whole-house ventilation fans. Visit the US Department of Energy Energy Savers website for more information.

Another great resource is the Database of State Incentives for Renewables and Efficiency or “DSIRE” website. This allows you to view rebates, loan and grant programs, financing options and tax credits offered in your region.

Finally, new home buyers should consider an energy-efficient mortgage or energy improvement mortgage. These mortgages allow consumers to count savings from energy bills as additional income, ultimately giving them more buying power.
