The Sun Haven: Solar-Powered Net-Zero Energy House Featured in Lincoln’s Spring Parade of Homes


This year Lincoln-based GRNE Solar teamed up with Wilderness Construction to build a beautiful net-zero energy home with solar on the roof and outlets for electric vehicles in the garage. The home, called the Sun Haven, is located at 6077 Chartwell Lane in Lincoln. Through the use of solar power this home will produce as much energy as it consumes.

GRNE Solar is featuring The Sun Haven on the Home Builders Association of Lincoln’s Spring Parade of Homes through this Sunday, May 20th. The company will host educational sessions on solar energy, as well as free “Solar Potential” studies for home buyers..

Admission is FREE to view the homes in the Parade.

Thank you to all who attended yesterday’s tour of Karen & Darren Dageforde’s Net-Positive Energy Home!

First of all, thank you to our hosts, Karen and Darren Dageforde and their son, Pierce: Karen for providing an excellent presentation on their all-electric home’s many green building and clean energy features, and to all three of them for providing individual discussions and tours afterwards. Karen also talked about their family’s commitment to saving energy, water and other natural resources and provded steps attendees can take in their own homes.

Many thanks, too, to everyone who made the beautiful drive to attend the event, coming from Blair, Omaha, Bellevue, Lincoln, Council Bluffs and as far away as Seward!

Built in 2010, the home’s features include a passive solar design; huge windows for natural lighting; insulated concrete-form floors and walls, which prevent air infiltration and loss, a major contributing factor to the typical home’s energy costs; Energy Star windows and Energy Star appliances; R-50 attic insulation; 5 closed-loop geothermal wells for heating, cooling and hot-water generation; a 5-ton HVAC system; radiant flooring that provides free cooling; and photovoltaic (PV) systems: 18 panels installed in July 2011 and 14 in May 2016.

  • These were both do-it-yourself projects designed and installed by Karen and Darren.
  • The total energy generated by their PV system in 2017 was 11,303 kilowatt hours (kWh), providing 100+% of their home’s energy needs!

The cost of designing and building their net-positive energy home was very comparable to the cost of a conventional build.

Karen, now retired, holds a degree in accounting, and Darren, director of utilities in UNMC Facilities, Management and Planning, has a degree in mechanical engineering. They are also volunteers at the Washington County Recycling Center, working alongside others to sort boxes of cans and bottles, paper and plastic.

They and their son Pierce “walk the walk” in this area, too, in a variety of ways and encourage others to do so, as well, as they did yesterday, including: not only recycling but also purchasing recycled products; trading with others; buying in bulk, thus reducing packaging, and taking reusable, washable containers to stores, including mesh produce bags; and repurposing materials, as Karen and Darren did when they recovered lumber that had been thrown away to build their chicken coop.

Each one of these steps conserves energy, water, and other natural resources over the manufacturing and use of new things.

Following up on the Dageforde family’s inspiring presentation, handouts, and individual tours and discussions yesterday, the links to resources, below, provide additional information on energy conservation and renewable energy incentives for homes and businesses.

Morrissey Engineering takes diligent approach to “being green”

By Kevin Warneke, Omaha World-Herald

Morrissey Engineering takes sustainability seriously, said founding principal George
Morrissey . . .  “When we decided to build new in 2008, we knew that sustainability had to be featured throughout the building,” Morrissey said. The return on that investment came when the company earned platinum, or top, certification for its environmental performance from the U.S. Green Building Council. Read the entire article here.

She’s building what’s believed to be Nebraska’s 1st earthship, a unique style of home that ‘attracts a certain type of person’

By Chris Peters, Omaha World-Herald

“The whole idea is you’re off-grid, you’re completely sustainable, you have your own water, you grow your own food,” said Cathy Krueger, the owner. “It attracts a certain type of person.”

The earthship concept was created in the 1970s by architect Mike Reynolds in New Mexico. “Gunsmoke” actor Dennis Weaver, a noted environmentalist, built one in the ’80s.

Puerto Rico’s Devastated Electric Grid Could Be a Big Opportunity for Renewable Energy

By Justin Worland, Time Magazine

Authorities acknowledge they need months before power returns to some regions. Still, energy experts say the rebuilding effort offers a unique opportunity to outfit the island with the electric grid of the future: a state-of-the-art system built from scratch using renewable energy sources like wind and solar, which would be cheaper to operate and would respond better to the next hurricane. The reimagined grid would rely on the concept of a microgrid, which are localized electric grids that allow communities to keep power even if centralized power plants are not functioning.

The power of solar energy

Written by Fremont Tribune Staff

After survey results indicated that a large portion of Fremont residents are interested in solar energy, the Fremont Department of Utilities is moving forward with planning a community solar farm in Fremont. More than 70 percent of Fremont’s residential population responded through an August, 2016, survey saying that they were interested in getting power from a community solar farm. The first step in the process will be to present information about community solar at the Fremont Home and Builders Show held Friday through Sunday at Christensen Field Community Center. Read the entire article here.

The dawn of architectural solar

By David Beckham, Director of Building-Integrated Photovoltaics at Walters & Wolf. Published by GreenBiz News.

Since the beginning of the modern architectural era, humankind has dreamed of self-sustaining buildings that generate their own power. Futurists of the early 20th century looked ahead to the days when the sun would power our homes and commercial buildings and we would be transported to and from our workplaces in flying cars. Unlike the overly ambitious estimates concerning personal air transportation, today the concept of a solar-powered building is neither remote nor unachievable. Continue reading.

SAN JOSE, CALIF. / PR Newswire – Energy-efficient homes of the future have arrived and are growing in popularity. According to a report by McGraw Hill Construction, nearly one-third of new single-family homes in the U.S. will be green by 2016. They are energy and natural resource efficient, designed to reduce overall impact on human health and the environment. An increased number of consumers are going a step further and striving for net-zero energy homes that use renewable energy solutions, such as solar power systems, to offset all or most of their energy consumption. Across the country, the number of net-zero energy residential and commercial buildings doubled between 2012 and 2014 as cited by the New Buildings Institute.

Experts predict the trend will continue.
