Buyers Benefit From Having an Agent Who Knows Home Systems and Sustainability

One of the reasons I enjoy showing homes to buyers is that I get to educate them about home systems and how they work, as well as identify the sustainable and not-so-sustainable features of each home.

The agents at Golden Real Estate have a thorough understanding of home systems as a result of our combined decades of experience and hundreds of transactions. In addition, we have taken classes on energy efficiency, insulation, solar power and home construction which allow us to serve buyers better when we show them homes.

Together, for example, we toured the model homes at Richards Farms when they were under construction, where we learned, among other things, about that builder’s foam insulation process.

There are so many aspects of energy efficiency and sustainability. Everyone by now knows about solar photovoltaics — creating electricity from the sun. Our office has 20 kW of solar panels, but having solar power is only the beginning. It’s how efficiently you use that power that makes the difference.

Heating and cooling is the biggest user of energy in any home, and the number and variety of HVAC systems have become more extensive and more complicated, and we understand and can explain them. They include: gas forced air heating and compressor-based air conditioning (most common in Colorado and much of the country), hot water baseboard heat, hot water radiant floor heating, wall-mounted heating panels or strips, heat pump mini-splits for both heating and cooling, hybrid heat-pump with gas forced air (which Rita and I have in our home), ground-source heat pump for both heating and cooling (the “gold standard” of efficient heating and cooling) — and let’s not forget heating with wood or wood pellets!

Windows can vary greatly. Double-pane windows may be standard now, but a Colorado company, Alpen, has made a name for itself with triple-pane windows and now quadruple-pane windows.  Recently I wrote about John Avenson’s Westminster home, in which some of his south-facing Alpen windows have micro-etching to divert sunlight toward the ceiling of his kitchen, a high-tech alternative to reflective window shelving, which we saw when we toured a newer building at the National Renewable Energy Laboratory.

Skylights are so 20th Century. Today’s modern replacement are sun tunnels (Solatube is a leading brand), which are great for illuminating interior rooms. Just last week I showed a home with five Solatubes in it, lighting up the living room and an interior bathroom amazingly well from the mid-day sun. My buyer didn’t realize they weren’t ceiling light fixtures until I pointed them out. (We have two sun tunnels in our home illuminating our windowless garage and laundry room, and we have four sun tunnels in the Golden Real Estate office. We don’t have to turn on any lights on sunny days!)

A knowledgeable agent can also point out passive solar features of a home, which others might not recognize. These include proper window configuration, wide overhangs above south-facing windows, thermal masses in south-facing sunrooms, and deciduous trees providing strategically positioned shade in the summer but allowing more sunlight in the winter. I like to see (and point out) cellular shades, especially vertical ones covering patio doors for cold-weather insulation.

Often I notice that the listing agent didn’t mention the features (such as the Solatubes) that my buyers and I recognize as selling points. Of course, when doing the narrated video tours of our own listings, my broker associates and I don’t miss the opportunity to point out those features. And, of course, we are sure to mention those features in the MLS listing.

Many agents miss the opportunity to write a separate description on the MLS for each individual room. It’s not a mandatory field, but it’s the best place to mention a room’s Solatube, heated floor, porcelain tile, hardwood or other feature.

John Avenson of Westminster Is a Committed Teacher of Energy Efficiency

The sponsors of the annual Metro Denver Green Homes Tour, held on the first Saturday each October, are preparing to “go virtual” in case an  in-person tour is not allowed.

That will be accomplished by creating online video tours of the most notable “green” homes featured over the past 20 years. Since I’m on the steering committee for the tour and have the equipment and experience from creating video tours of homes for sale, I volunteered to create those video tours, starting with John Avenson’s home at 9988 Hoyt Place in Westminster.

By clicking here, you can view the 41-minute video tour, led by John, which I created last Friday. It is highly educational.

John Avenson

Many people, myself included, have created homes which can be considered a “model” of sustainability, solar power, and energy efficiency, but John is surely the only homeowner who has turned his home into a classroom for teaching it. He even posted pictures and diagrams throughout the house with instructional content about this or that feature, as you will see on that video.

He also hosts monthly Passive House meetings in his home theater which are also streamed online. They can be found at www.meetup.com/Passive-House-Meetup-S-W-Region/

John’s house was originally built by the Solar Energy Research Institute (SERI, now the National Renewable Energy Laboratory or NREL) in 1981 using then-state of the art technology, but John has diligently, and at great personal expense, kept retrofitting his home with newer technology, which he is happy to explain to visitors and which he explains on the 41-minute video.

For example, because of increased insulation and Alpen quadruple-paned windows, he was able to get rid of SERI’s supplemental natural gas furnace, installing a conditioning energy recovery ventilator (CERV) which is powered electrically. His grid-tied solar PV system provides all his home’s energy needs and has reduced his Xcel Energy bill to under $10 per month — the cost of being connected to the electrical grid.

Some of the technological innovations featured in my video with John were new to me. For example, the Alpen windows across from his kitchen have horizontal micro-etching which redirects the sun’s rays 90° upward to his ceiling instead of straight through the glass, reducing the need for lighting.

John provided his email address in the video, saying that his “learning center” is open 24/7 and that he welcomes all inquiries and visitors.
