Importance of Home Energy Efficiency  Residential energy consumption accounts for over 20% of global energy use.  In 2001, homeowners, on average, spent $1500 on energy costs.  Energy bills are usually the largest portion of housing costs after rent or mortgage payments.  In 2007, residential carbon emissions grew to 1242 million metric tons of carbon.  Increasing price of energy.

Energy Efficiency 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.

Energy Efficiency 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  In 1994, the pilot was expanded to ten states.  In 1995, the pilot was expanded as a national program.  Green Energy Act of 2008 Section 9 Section 8 Section 25

Energy Efficiency Types of EEMs  Conventional EEM Most powerful of the EEMs Borrow up to 15% of the home’s appraised value for improvements.  FHA EEM: Not as powerful as the conventional EEM. Borrow up to 5 % of your home’s value (though not more than $8,000) or $4,000, whichever is greater  VA EEM: Past and present military personnel Allows you to spend up to $6,000 for energy efficient upgrades Regardless of the value of the home.

Energy Efficiency How EEMs Work  Backed by private and government mortgage programs  No additional down payment.  In most cases you already qualify for an EEM.  Funded by a lending institution, such as a mortgage company, bank, or savings and loan association  Aren’t second mortgages, rolled into primary mortgage.

Energy Efficiency Home Energy Rating System (HERS)  Overall rating index of the house as it is. Blower door test Manometer  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.

Energy Efficiency Efficiency  double paned windows  tankless water heaters  New HVAC units with air ducts  new insulation  Weatherizing  energy efficient heating and cooling systems  fixing or replacing a chimney  installing active and passive solar technologies

Energy Efficiency 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  Reduce carbon footprint  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  Savings Save money every month from day one Gas prices are rising building a home to exceed the Model Energy Code would result in an annual savings of $170 to $425.

Energy Efficiency Who benefits?  Buyers Qualify for a larger loan on a better home Save money every month from day one An average of 6.8% more families would be able to qualify Stretch debt-to-income qualifying rations on loans  Sellers Sell your home more quickly Make your house affordable Increase the resale value  Remodelers/refinancers Get EEM benefits without moving Make improvements which will actually save you money

Energy Efficiency Statistics – EEMs lower your carbon footprint!  Heating and cooling account for 50–70%.  60% not properly insulated.  In houses with central air and heating, about 20% of the air is lost due to faulty, outdated duct work.  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.

Energy Efficiency …Statistics – EEMs lower your carbon footprint!  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.  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.
