CRES ‘Teach-In’ This Saturday on Clean Energy Transformation

The Colorado Renewable Energy Society (CRES) is hosting a 1-day conference this Saturday, August 6th, “Renewables Powering Forward: Solutions for Our Clean Energy Transformation.” It runs from 9am to 5pm at the Jefferson Unitarian Church, 14350 W. 32nd Ave., Golden.

This conference is designed to illustrate key elements of today’s clean energy solutions. We are fortunate to have the National Renewable Energy Lab and the Colorado School of Mines and many energy innovation entrepreneurs and pro-active political leaders.

Keynote speakers include Hunter Lovins, and there will be sessions on solar power, home electrification and micro-grids. A light breakfast and lunch are provided, and all sessions will be recorded.

Tickets are as low as $25, with a virtual ticket for viewing the conference online available at $35. Learn more and register online at cres-energy.org/cres-conference-2022.

Green Home of the Month for March 2021

   Steve Nixon is a project manager at the National Renewable Energy Laboratory. He had this home built to his specifications in 2012. It has many passive solar features, solar photovoltaics, and a heat recovery ventilator, which are all explained  at GreenHomeOfTheMonth.com. Outside, it has a buffalo grass lawn requiring no water or mowing, and drip irrigation for its garden.

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.
