Homebuyers' Interest in Green Home Features Increases With Energy Efficiency Cited as Top Priority
ZipRealty.com Introduces Transit Scores in Conjunction With New Green Survey

EMERYVILLE, CA, Aug 17, 2010 (MARKETWIRE via COMTEX) -- More than half of all home shoppers report that green home features, from energy efficient appliances to solar panels, are an important part of their purchasing decision, though only one percent of home listings market these features to buyers, according to results of a national survey announced today by real estate brokerage ZipRealty (www.ziprealty.com) (ZIPR 2.70, +0.17, +6.72%) .

The brokerage also announced that it is the first real estate company to integrate green-friendly Transit Score ratings into current home listings on its popular home-buying site, based on the popularity of the existing Walk Score feature, which scores the walkability of each listing.

"A growing number of home shoppers are seeking out homes that offer strong public transit options, high walkabilty scores and green features," said ZipRealty's Chief Home Hunter Leslie Tyler. "Showing Transit Score ratings for all home listings on our website gives our clients additional information about alternative transportation that they need before making an offer on a home."

New Survey Indicates Green Features as a Priority A recent survey of homebuyers registered on ZipRealty.com revealed that 55 percent of survey respondents rated a home's green features a "somewhat important" or "very important" part of their home hunt.

Other highlights from the survey include:


-- Homebuyers who view green features as a priority ranked them important
because they helped save money (49 percent), as well as allowed them
to do their part to help the environment (40 percent).
-- Other reasons homebuyers valued green features included
occupant/family health (37 percent), tax credit availability (12
percent) and the home's resale value (15 percent).
-- Although homebuyers overwhelmingly rated energy efficiency the most
important green feature in a home (89 percent), an additional survey
conducted by the brokerage of MLS-listed homes across the 35 markets
nationwide ZipRealty serves found that less than one percent of homes
on the market included the term in their description of the home.




See below for a list of the top five green features for homebuyers.

"Sellers are missing an opportunity to market their home effectively to a wide net of home shoppers," said Tyler. "Appealing to buyers can be as simple as highlighting appliances as energy-efficient, which many homeowners choose today to save money themselves. Our survey suggests that sellers of older homes could make inexpensive changes, like switching to energy efficient light bulbs or appliances, to help their home stand out from others."

New Transit Score Ratings on ZipRealty.com In response to increasing buyer demand, ZipRealty also introduced the Transit Score feature as part of an updated website and logo revamp. Transit Score ratings rank a home on a 100-point scale based on its proximity to multiple public transportation options, allowing homebuyers to consider the amount of time and money they will spend commuting every day as part of their purchase decision.

ZipRealty is the first brokerage to feature the new Transit Score, an application developed by Seattle-based civic software company Front Seat. Homebuyers in most of the 35 markets ZipRealty serves will be able to locate Transit Scores along with Walk Scores (introduced in 2008), the relative "walkability" score for a home, under each listing's "Neighborhood Info" tab. Transit Score is calculated on the frequency, type of route (rail, bus, etc.), and the distance to the nearest stop on the route.

GREEN Siding Options

Reprinted from Houselogic.com, John Riha 9/2/09

Selecting green siding is a matter of weighing trade-offs in longevity, insulation, biodegradability, maintenance, and, in some cases, cost.

f you think you’ll pay a premium for selecting green siding for your home, think again. Many of the best sustainable choices are familiar materials that have been on the market for years. Some products are made with recycled materials and others have improved insulating qualities that add only a moderate increase in price. When choosing replacement siding, weigh the pros and cons of sustainability, thermal performance, and the cost of eco-friendly products.

Evaluate sustainability
When choosing siding, consider its sustainability. Sustainability is an estimate of how long a material will last; if the material can be recycled; if it contributes to health concerns; and if it’ll readily biodegrade in a landfill. Maintenance, too, is a key consideration. High-maintenance materials that require regular upkeep, such as repainting, and use additional resources and energy over their lifecycle, are less sustainable.

Improve energy performance
A siding replacement project offers an excellent opportunity to boost your home’s energy performance and make your house healthier. Adding a house wrap (which prevents water infiltration and air leaks) and rigid-foam insulation is one of the best ways to reduce energy consumption and protect your home from moisture condensation inside walls—a major source of mold problems—no matter what type of siding you choose.
Adding insulation increases R-value—a measure of insulation performance. A house with 3-1/2-inch stud walls filled with fiberglass insulation has an R-value of about R-12. Adding rigid foam and house wrap can boost insulating performance to between R-16 to R-20, reducing your annual energy costs 5% or more.

Costs of green
Siding replacement has proven value. A siding replacement project using foam-backed vinyl siding returns more than 80% of its initial cost at resale, according to Remodeling magazine’s Cost vs. Value Report—one of the highest values in the annual survey.
Because many types of siding are extremely long-lasting, they can be considered green options, but without a premium price. However, improving thermal performance—and, therefore, boosting the siding’s greenness—with house wrap and rigid-foam insulation adds cost—about $1,800 for an average house, according to Fine Homebuilding magazine. Many green consumers feel that contributing to a healthier, sustainable environment is more important than higher initial costs.

House wrap
House wrap is a thin, tough, semi-permeable membrane that’s applied over the outside of wall sheathing and under the siding. It’s designed to block water and reduce air infiltration while allowing moisture vapor to pass through.
Sustainability: Extremely durable and long-lasting, this flexible, plastic material is recyclable.
Energy efficiency: Using house wrap, along with properly sealed joints at windows and doors, can reduce air infiltration and save on annual energy bills. Some varieties, such as DuPont’s Tyvek ThermaWrap and Low-E Housewrap from Environmentally Safe Products include heat-reflective layers that increase insulation performance by a factor of R-2.
Cost: 25 cents to 50 cents per sq. ft., installed
Rigid-foam sheathing
Rigid-foam sheathing is lightweight, easy to apply, and comes in a variety of thicknesses. Unlike fiberglass insulation, which fits between studs, sheathing blankets the entire exterior wall. It can be applied directly over existing wall materials, such as hardboard, stucco, and wood, providing a smooth substrate for new siding.

Sustainability: The manufacture of extruded polystyrene (XPS) sheathing is associated with the production of chlorofluorocarbons (CFCs), which damage the ozone layer, although some manufacturers are researching CFC-free production methods. Expanded polystyrene (EPS) foam sheathing doesn’t produce CFCs and is considered environmentally friendly. EPS can be recycled but doesn’t degrade readily in landfills.

Energy efficiency: Insulating values of R-3 to R-7 per inch thickness.
Cost: 20 cents-$1 per sq. ft., depending on thickness and thermal performance.
Insulated vinyl siding
Insulated vinyl is similar to regular vinyl siding, except it includes a layer of EPS foam insulation. Its thickness makes it more rigid and easier to work with than regular vinyl.

Sustainability: Vinyl requires little maintenance and will last 30 to 50 years, but it’s made from polyvinyl chloride (PVC), a chemical compound that doesn’t degrade in landfills. During manufacturing, PVC produces byproducts that include dioxin. Vinyl siding can be recycled.
Energy efficiency: Adds approximately R-3 to walls
Cost: $3-$8 per sq. ft., installed; 15-30% more expensive than regular vinyl

Fiber-cement siding
Fiber-cement siding is a low-maintenance product made from sand, Portland cement, clay, and wood pulp fibers. It’s termite-proof, fire-resistant, and doesn’t rot.
Sustainability: Extremely durable and long-lasting, it’s available with low-maintenance finishes that last for decades. But fiber-cement carries high embedded energy—the energy necessary to fire the kilns that heat its raw materials. Any energy expended toward a material ads to its carbon footprint. The newest varieties are lighter and include more recycled material.
Energy efficiency: Negligible R-value, but its superior stability helps keep the building envelope free of cracks and caulk failures.
Cost: $5-$9 per sq. ft., installed

Wood
Unmatched beauty makes wood a premier choice for siding.
Sustainability: Although a precious natural resource, wood is a renewable product that can be recycled and readily degrades in landfills. To ensure the wood products you buy are harvested from sustainable, managed forests, look for certification stamps from the FSC (Forest Stewardship Council) and the SFI (Sustainable Forest Initiative). Wood siding is a high-maintenance siding that requires refinishing every two to five years.
Energy performance: Wood is a natural insulator, but as a siding it offers a minimal R-value of about R-1.
Cost: $6-$9 per sq. ft., installed

Stucco
Traditional stucco is made from sand and Portland cement mixed with water to make a workable plaster. Modern stucco often includes epoxies to harden the material. It’s tough, durable, and resistant to insects and fire. Well-maintained stucco will last for the life of the house.
Sustainability: Eco-friendly varieties of stucco are made with an earth-and-lime mixture instead of Portland cement and epoxy, reducing the embedded energy and CO2 emissions associated with cement production. Painted stucco requires periodic touch-ups and repainting every 5-7 years.
Energy performance: Negligible thermal performance, but effective at reducing air infiltration while remaining permeable to moisture vapor.
Cost: $6-$9 per sq. ft., installed

Engineered wood
Engineered wood products are made from wood fibers, resins, and wax. They’re pressed in molds to create panels resembling real wood lap siding and shingles.
Sustainability: The high wood waste content of engineered siding boosts its sustainability factor. Engineered siding comes with baked-on factory finishes that reduce maintenance, but warranties of about 20 years are less than for other types. It easily biodegrades in landfills.
Energy performance: Negligible
Cost: About $2-$4 per sq. ft., installed
