Regional Multiple Listing Service Launches New Measure to Connect Realtors and Buyers Looking for ‘Green’ Homes
Home Performance Measure Recognizes Certified Homes as Earth Advantage®, ENERGY STAR®, and LEED® for Homes
As rising energy costs and global warming concerns impel more consumers to make money-saving and green choices, home buyers in Oregon and Southwest Washington can now shop specifically for energy efficient, sustainable homes. This new drop-down feature adopted from Oregon’s Regional Multiple Listing Service (RMLS™) titled “Home Performance” will enable realtors to search for and find homes certified as Earth Advantage, ENERGY STAR or LEED for Homes in the local market.
“This is a wonderful step in the right direction," states Duane Woik, green building consultant for Earth Advantage. “Oregonian’s care about the environment and are very educated on energy conservation. But the missing piece has always been how to find the right home that matches those lifestyles. With the new measure being implemented by the RMLS, home seekers can now find exactly what they’re looking for.”
Launched on February 28th, the RMLS has expanded its database to include information on energy efficient and green home measures made searchable, making this region one of the few in the nation where this service is available. The drop-down feature will allow realtors to find performance tested and certified homes within the Portland and SW Washington market. In addition, specific features and products can be found by selecting energy efficient or sustainable products such as a high efficiency 90-percent+ gas furnace or high efficiency heat pump, solar electric or water heating systems and modifications such as sustainable materials, water filters, rain collectors and solar tubes or skylights.
Given the rising popularity and significant benefits of energy efficient and green home features, these new RMLS capabilities will formalize the additional value these features bring to a home. In particular, potential buyers will be able to easily identify homes that
incorporate a comprehensive suite of energy efficient and green features that are third-party certified to save energy, money and natural resources.
“Green and energy efficient features have emerged as some of the most important and sought-after by buyers in our RMLS service area,” said RMLS CEO Beth Murphy. “With the help of their realtor, homebuyers can now pinpoint homes with these features.”
This decision from the RMLS Board of Directors came in response to a proposal spearheaded through the cooperative effort of Earth Advantage, Inc., ENERGY STAR and local Green Realtor, Kria Lacher.
Remodel Green and Curb Your Energy Costs
The National Association of the Remodeling Industry (NARI) offers alternative energy guidance.
Energy prices continue to climb, but the good news is that the cost barrier to using green energy is dropping. People are seeking out alternative energy sources that are abundant, environmentally sound and cost effective. Technology continues to evolve that helps us channel energy from the sun. The sun’s energy can provide space heating, hot water heating and electricity for lights and appliances.
The U.S. is dependent on fossil fuels such as coal, oil and natural gas for its energy, and is highly reliant on foreign oil imports. Fossil fuels are of finite supply, meaning their supplies will ultimately diminish to the point of becoming too expensive or too environmentally damaging to salvage. Renewable energy resources, however, such as solar energy, are inexhaustible.
Solar retrofits are solar energy applications made for an existing home. Since solar energy is an endless, environmentally friendly energy source, using it lowers utility bills. When retrofitting, the first stage of the project is to make a record as to how energy is currently used in the home so that the right product may be chosen. Next, determine how much sun is available. The amount of solar energy available to a home is largely dependent on the time of year and your home’s location. For example, homes in the northern hemisphere need a southeast to southwest orientation to maximize solar energy. You will also want to assess sun availability by looking at what obstructions there are on the south side of the home, such as trees or taller buildings. Solar energy retrofit options may include active and passive solar, photovoltaics, wind and geothermal.

Passive Solar Heating
Passive solar is the most cost effective approach to maximizing the use of solar energy for your home. Passive solar heating of homes is simple: it occurs when sunlight passes through a window, and no additional equipment is used to harness the energy. Passive solar applications use building elements such as walls, windows, floor and roof in addition to exterior building elements. Landscaping can control overheating by providing shade and provide windbreaks for winter winds. Once heat is collected inside, a well-insulated airtight “building envelope” helps prevent heat loss and allows the sun to provide more of the heat needed by the house.
Active Solar Systems
Active solar systems use solar collectors and a pump or a fan to distribute the sun's energy. Active systems are often used for heating water. The collector is a dark color to absorb the sun's energy and converts it into heat. Some collectors have a glass cover, collecting solar energy all year. Domestic hot water requirements can be met in part by active solar systems. In most cases solar energy will only provide some partial water requirements during the winter, but most of the summer season requirements. In most applications the solar system is used to preheat water going into a conventional water heater. Outdoor swimming pools can be entirely heated by solar systems, eliminating the need for a supplemental heater.

Photovoltaics (Solar Electricity)
Sunlight converted directly to electricity through solar cells is called photovoltaic (PV) energy. Solar cells come in an assortment of sizes and will produce electricity as long as sunlight shines on them. Solar cells used for electrical generation are really just a more sophisticated version of the solar cells used in calculators and other small household electronic devices. PV cells generate direct current (DC), meaning that to use PV-generated electricity directly, DC appliances and lights must be used. These are most often used in recreational vehicles. In order to use standard household appliances the power must be converted to alternating current (AC), which is the form supplied by utility companies. So a solar electric system must be designed to convert the power to AC.

Geothermal or ground source heat pumps, take stored solar energy from the soil and bodies of water. They rely on electricity, but provide the equivalent of three times KW heat for every kilowatt delivered. Heat pumps are reversible, supplying cooling and heating, so they can be useful in areas with significant cooling loads.

Think about Conservation
While you’re deciding what the best options are in solar energy for your home, think about conservation as well. Draft-proof your home and upgrade insulation for optimum energy conservation. A remodeling project is a prime opportunity to undertake upgrades like wall and ceiling insulation, air sealing and installing new energy-efficient windows. New windows should be high performance windows with low-e glass, gas fill and insulating spacers. You can maximize cooling with roof overhangs that block direct sunlight.
