Beginning March 2009, the Florida Energy Code will become 15% more stringent.

Solar water heaters can provide a significant reduction in Energy Code points.

If you’re looking to be green, solar water heaters are now a line item on the FGBC checklist.

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

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.

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 1992.

In 1994, the pilot was expanded to ten states.

In 1995, the pilot was expanded as a national program.

Energy Efficiency

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.

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

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

Energy Efficiency

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.

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.

Energy Efficiency

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.

Energy Efficiency

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.
