  15. What is an Energy Efficient Mortgage (EEM)? • A mortgage that credits a home's energy efficiency in the home loan. • Let you borrow extra money to pay for energy efficient upgrades to your current home or a new or old home that you plan to buy. • EEMs recognize that reduced utility expenses can permit a homeowner to pay a higher mortgage to cover the cost of the energy improvements on top of the approved mortgage.

  16. How EEMs Work • Backed by private and government mortgage programs • Designed to help you make your home more energy efficient. • Do not have to qualify for the additional money and do not make a down payment on it. • The mortgage loan is funded by a lending institution, such as a mortgage company, bank, or savings and loan association • Aren’t second mortgages, rolled into primary mortgage.

  17. History • In 1992, Congress mandated a pilot demonstration of Energy Efficient Mortgages (EEMs) in five states under Section 513 of the Housing and Community Development Act of 1992. • In 1994, the pilot was expanded to ten states. • In 1995, the pilot was expanded as a national program.

  18. How do you get an EEM? HERS report (Home Energy Rating System) - an evaluation of how energy efficient a home is. A trained Energy Rater goes to your home. Factors: insulation, windows, heating and cooling systems, and local climate. Basically, if you already qualify for a regular mortgage, then in most cases you already qualify for an EEM. The actual energy efficient improvements must be cost effective.

  19. What are the benefits? • Increases Purchasing Power • An average of 6.8% more families would be able to qualify for a mortgage through an energy efficient mortgage. • Stretch debt-to-income qualifying rations on loans • Increases Market Value of Homes • The market value of a home increases $20 for every $1 decrease in the annual energy costs. • An estimated increased home market value of between $4,250 to $10,625. • Comfort • Cooler in the summer • Warmer in the winter

  20. Who benefits? • Buyers • Qualify for a larger loan on a better home • Get a more comfortable home • Save money every month from day one • Increase the potential resale value of your home • Sellers • Sell your home more quickly • Make your house affordable to more people • Remodelers/refinancers • Get all the EEM benefits without moving • Make improvements which will actually save you money • Increase the potential resale value of your home.

  22. Home Energy Rating System (HERS) • Overall rating index of the house as it is. • Recommended cost-effective energy upgrades • Estimates of the cost, annual savings, and useful life of upgrades • Improved rating index after the installation of recommended upgrades • Rating index is between 1 and 100. • usually costs between $300- $800.

  23. Types of EEMs • Conventional EEM: This type of loan is offered by lenders who sell their loans to Fannie Mae and Freddie Mac. It is the most powerful of the EEMs as it allows you to borrow up to 15% of the home’s appraised value for improvements. • FHA EEM: This type of EEM is not as powerful as the conventional EEM, but you will be able to take advantage of the benefits of FHA financing. You can borrow up to 5 % of your home’s value (though not more than $8,000) or $4,000, whichever is greater • VA EEM: This version of the EEM Mortgage is for past and present military personnel and allows you to spend up to $6,000 for energy efficient upgrades when purchasing an existing home regardless of the value of the home.

  24. Statistics – EEMs lower your carbon footprint! • Overall, heating and cooling accounts for 50–70% of the total energy used in the average American home. • 60% of the existing homes in the US are not properly insulated. • Updating your home’s insulation can save you up to 20% on heating and cooling costs or up to 10% of your total yearly energy bill. • According to the Department of Energy, energy loss from outdated windows accounts for nearly 25% of the annual heating and cooling costs for the average American home. • Even the most basic double-paned window can reduce energy use by up to 24% in cold climates during the winter and by up to 18% in hot climates during the summer. • In houses with central air and heating, about 20% of the air is lost due to faulty, outdated duct work. • A new Energy Star-rated dishwasher can save you up to 13 energy (the dishwasher accounts for 2% of your gas or electric bill) and as much as 1,200 gallons of water a year. • Programmable thermostats can save about 2% on heating bills and more than 3% on cooling bills. These numbers can translate into savings of up to $180 a year.

  25. Energy Efficiency Rebates Energy Efficiency Rebates are created by the government and most are carried out by the utilities Mass Save helps to carry out additional energy efficiency rebates Many rebates deal with EnergyStarqualified products

  26. Energy Efficiency Rebates • The two utilities in the Boston Area who offer rebates are National Grid and NStar • Rebates can apply to: • Lighting and appliances • Income eligible programs • Heating and cooling • Building a house or addition, Retrofits • Programs for multi-family home owners

  27. Lighting and Appliance Rebates • A $50 rebate for purchasing an eligible EnergyStar refrigerator or freezer • The utility company will pay you $50 to come pick up your second fridge or freezer! • A $50 rebate is available when you purchase an eligible Energy Star refrigerator or freezer in 2011 • Order a Smartstrip by Dec 31st and get a $10 rebate and free shipping • $20 towards purchase of energy star qualified room air cleaners bought in 2011. • $200 towards purchase of eligible energy efficient pool pumps • Buy an EnergyStar qualified desktop computer and receive $10 incentive. Buy an EnergyStar qualified monitor and receive $20 incentive.

  28. Heating and Cooling Rebates • $400 rebate for a high-efficiency indirect fired water heater connected to a natural gas heating system. • $400 rebate for a natural gas warm air furnace with an electronic commutated motor (ECM) an an AFUE Rating greater or equal to 92 percent. • $300 for customers replacing an existing oil/propane fire tankless or freestanding hot water heater with an indirect fired water heater • $200 rebate for after market boiler reset controls connected to a natural gas boiler. • $25 toward the purchase and installation of an EnergyStar qualified or seven day thermostat that controls an oil or propane fired heating system • 75% off up to $2000 towards insulation upgrades • $100 rebate for an ENERGY STAR-rated storage water heater with an Energy Factor greater or equal to .67. • $50 rebate for an ENERGY STAR-rated storage water heater with an Energy Factor greater or equal to .62. • $500 for qualifying condensing water heaters • $400 for qualifying indirect water heaters • up to $100 for qualifying storage, tank-type water heaters • Installing a reset control can increase your boiler's efficiency. By differentiating between colder and milder weather, the control signals the boiler to operate at an applicable level, saving ten percent or more on your heating costs. • Upon installation of an add on outdoor boiler, a reset control attached to your existing forced hot water boiler means you will qualify for a $200 rebate from National Grid.
