Some research projects in California, Oregon and Washington offer hints that energy efficiency and sustainability certifications for homes may result in easier sales and higher prices.
Home energy efficiency and sustainability have been major policy priorities for the Obama administration, but lurking in the background are two consistent questions: Beyond the documentable savings on utility bills, do such steps add to the resale value of a home? And do they make it easier or faster to sell your property?
Housing groups and housing officials say that definitive statistical data covering multiple regions of the country are scarce. But some localized research projects in Oregon, Washington and California offer promising hints.
In a study covering existing and new houses sold from May 2010 through April of this year, the Earth Advantage Institute, a nonprofit group based in Portland, Ore., found that newly constructed homes with third-party certifications for sustainability and energy efficiency sold for 8% more on average than noncertified homes in the six-county Portland metropolitan area. Existing houses with certifications sold for 30% more.
The raw sales data in the study were provided by the Portland Regional Multiple Listing Service. “Certified” houses were defined as those carrying Energy Star or LEED for Homes designations or Earth Advantage home certifications. (LEED stands for Leadership in Energy and Environmental Design.) The latest study was the fourth in an annual series conducted by Earth Advantage, each of which has shown clear price premiums for certified houses.
But officials caution that using average sales prices pulled from MLS data without trying to measure “comparable” homes against one another directly may not be conclusive. For instance, newly constructed certified houses may be more expensive to start, and existing certified homes may be larger and more likely to be in higher-cost neighborhoods where homeowner adoption rates for energy-efficiency measures are higher.
Nonetheless, said Dakota Gale, Earth Advantage’s manager of sustainable finance, looking back at four years of studies, “we can still see a consistent trend that third-party certification continues to result in a higher sales price, even during the past year when home sales were down.”
A study conducted two years ago by the institute in Seattle and Portland identified what may be another plus: Homes marketed with energy-efficiency certifications appear to sell faster on average than those without. The study tried to come up with rough comparability in appraisal terms between certified and noncertified properties, and it found that in Portland, certified homes spent 18 days less time on the market after listing than noncertified counterparts. In both Portland and Seattle, researchers documented price premiums — 9.6% in Seattle, 4.2% in Portland — in a statistical analysis with a 95% confidence level.
A recent study on houses in San Diego and Sacramento published by the National Bureau of Economic Research took a different tack: When you install photovoltaic solar panels on your roof, how much do you get back in market resale terms, beyond monthly energy savings?
Researchers examined a sample of home sales in the $500,000 range in both metropolitan areas between 2003 and 2010 and found that, on average, solar panel installations cost owners $35,967. But with federal and state subsidies, the net average cost came down to $20,892. This net expenditure, in turn, yielded an increase in appraised value by $20,194 — a 97% rate of recovery on the investment.
Though less than 100%, the rate is much higher than most home improvements in the most recent “Cost vs. Value” study conducted by Remodeling magazine — well above major kitchen and bathroom renovations.
Kevin Morrow, senior program manager for green building at the National Assn. of Home Builders, says that although many newly constructed homes come with energy and sustainability certifications, banks don’t necessarily recognize their value when it comes to providing mortgage money.
For example, bank underwriters often do not include reduced monthly utility costs in the household income/household expense ratios that affect the maximum mortgage amounts available to buyers.
“The case needs to be made” to lenders, he said, “that, hey, these houses will cost less to operate, so they should be worth more.”
Morrow added that appraisers are part of the issue as well if they don’t have the training to recognize and credit extra value to houses that have money-saving solar installations, geothermal heating and cooling, Energy Star appliances, water conservation features and other green improvements.
The Appraisal Institute, the largest group representing that industry, says it has sponsored “green” appraisal courses for 2,300 appraisers during the last two years. It says it strongly supports efforts to better incorporate energy and environmental factors into mortgage underwriting and home valuations, including a possible congressional mandate requiring it.
David Hakimi is a lighting specialist and one of the co-founders of Alcon Lighting. A graduate of the University of California Los Angeles (UCLA), David works on the front lines of the energy-efficient lighting revolution, enabling architects, designers, and lighting engineers to transition from outmoded halogen and fluorescent lighting. David takes particular pride in Alcon’s design, energy, and green building knowledge, tracing his and Alcon’s commitment to quality, innovation, accountability and value back to the lessons learned from his father, a Southern California lighting salesman and consultant for more than two decades. Passionate about climate change and protecting the environment, David has been particularly valuable in ensuring that his clients and customers comply with rapidly-evolving green building codes.
At Alcon Lighting’s LA headquarters, co-founder David Hakimi adopted a 12 year-old dog named Nano and decided to bring him into the office every day. Let’s just say it garnered some attention. It quickly became clear that Nano, who’s now 14 years old, relishes a long nap. Nano likes to hop and curl up in an easy chair, resting his head on the arm, drifting into slumber. In fact, David says this is Nano’s favorite activity.
If the work of lighting design was just left to services engineers to meet regulation-determined illuminance criteria per application, then interior and exterior architectural spaces would become soulless environments. Using qualitative measurements, architects and lighting designers can make sure the architectural intention and aesthetic character of a space is not compromised.
“98% of what gets built today is sh**. There’s no sense of design nor respect for humanity or anything. They’re bad buildings and that’s it.” – Frank Gehry. Fun fact: One of Frank Gehry’s most famous works as an architect is his own private Santa Monica residence.
The term Architectural Lighting encompasses three main factors. The first is the building’s aesthetic, which is crucial for any commercial, especially retail, environment. The second consideration is ergonomic or functional — any aspect which improves one’s ability to live, work, function, relax or play — to make the space easier to use. The third aspect involves the efficiency of energy, ensuring that light is properly, which is to say economically or optimally, used and distributed.
In 2016, Architectural Lighting interviewed lighting designer and founder of Pfarré Lighting Design, Gerd Pfarré, shedding light on the legendary designer’s process, what’s most important when lighting a space and what the future holds for lighting. While Pfarré’s is a career is a storied one, he did not start out in the industry.
