Free Energy Code Training In Action
Matt Waring with Richmond Metropolitan Habitat for Humanity shares his experience:
Richmond Metro Habitat and Viridiant came together to provide free trainings for code officials and contractors to aid in the adoption and implementation of the 2018 IECC Code update. Viridiant is currently offering statewide training to ensure Virginia is enforcing the code as written and, in turn, realizing the savings inherent to achieving the level of performance outlined by the latest code iterations.
The training utilized two, side-by-side, new construction homes located on Veranda Avenue within the City of Richmond. They focused on the process by which a home’s thermal envelope is tested for air leakage and the intent behind that test, as it is now mandatory for all new construction homes across the commonwealth under the uniform statewide building code. A similar process is utilized for duct testing to ensure conditioned air is moved effectively and efficiently to it’s intended location within the home. HVAC Systems are one of the leading energy using systems in a home and code is making big strides in ensuring that these systems are installed in a thoughtful and quality manner. Uncontrolled duct leakage is not only an energy penalty, but it also increases infiltration, causes comfort problems for occupants, and can lead to long-term durability concerns for structural components if left unchecked. The same can be said for envelope leakage on an even larger scale.
City of Richmond Plan Reviewers participated in the training along with the entirety of the Habitat Construction team. For Habitat’s part, seeing these tests in action on two identical homes and understanding the process and pitfalls, will be critical to ensuring durable homes for our homeowners for years to come, as these improvements to the envelope and duct systems pay dividends for the life of the home.

Viridiant to continue Circuit Rider work to implement the 2018 Energy Code
Viridiant is proud to announce that shared funding from the Southeast Energy Efficiency Alliance (SEEA) and the Pacific Northwest National Laboratory (PNNL) has been granted to build upon the 2020 Circuit Rider program. With the expansion of the circuit rider program, 10 jurisdictions in the Commonwealth of Virginia will receive complimentary technical assistance, Manual J review, Blower Door and Duct Blaster training, energy code implementation training resources, specialization for code review, and a forum for best practices amongst the jurisdictions.
This work will support Virginia’s implementation of the energy code. Ultimately, this will help Virginians reduce their energy cost burden. Additionally, implementation of the energy code and the technical work being provided by Viridiant will help homebuilders deliver resilient and healthy homes across the Commonwealth.
Viridiant has confirmed the participation of ten jurisdictions: James City County, the City of Hampton, Fairfax County, the City of Alexandria, Montgomery County, Franklin County, the City of Norfolk, Roanoke County, Warren County, and Southampton County. With the assistance of stakeholder feedback and through the tailored technical assistance offered to the participating jurisdictions, Viridiant has developed and distributed the 2018 Virginia Residential Energy Code resources. These resources have been deployed to all Virginia jurisdictions.
Viridiant and the Expanded Circuit Rider participants are eager to do the work. Linked are the full resources that were developed from the 2020 program to aid in the 2015 Virginia Residential Energy Code.
SolarizeRVA Helps the Richmond Region go Solar
SolarizeRVA Helps the Richmond Region go Solar
By: Andrew Grigsby, Energy Services Director
Do you have one of these (pictured left)? I bought this one in 1996, and it still works just fine. That’s right, 24 years old, and those tiny solar panels still power out trigonometry and lots of other things I still don’t quite understand. But my point is not to date myself, rather, it’s to demonstrate how durable and reliable solar panels are. Here we have cheap, quarter-century-old equipment that keeps chugging along. Of course today’s panels are as much improved as this year’s smart phones compared to the flip phone (or was it a car phone?) of 1996. They pack way more electricity-producing technology into each panel, such that many homes can now produce 50%, 75%, even 100% of their annual electricity needs with rooftop solar.
If you’ve been curious about solar for a while, Viridiant is launching a new effort to help you understand the technology, the logistics of an installation, tax credits, financing options, and the overall opportunity. We call it SolarizeRVA. And our goal is 1000 new solar homes in the Richmond region. This campaign is a continuation of a long-time project of the Richmond Region Energy Alliance, with whom Viridiant merged earlier this year.
Here’s how it works: You call us, email us, fill out our online form, or tune into a webinar or community meeting. We take a look at your roof (or yard/field) and your electric bill and talk through how much solar electricity you could generate and how that could work for you financially. We also discuss other energy-smart technologies and offer you an in-home energy analysis for as little as $45. Basically, you get easy access to some of Virginia’s most experienced residential energy and green building professionals to provide un-biased expertise without a sales pitch.
Over the coming months we’ll offer numerous public events where area residents can join in the conversation and have their specific questions answered. Our first is a webinar on Thursday, July 23 at noon – with an evening edition at 7PM. Register for free here. In addition to providing education, SolarizeRVA includes access to vetted installers to whom we can refer you.
It’s a great time to go solar. The federal tax credit of 26% is set to go down to 22% at the end of this year (details here). Installation on your roof takes just 1-3 days depending on the complexity of the operation, and 99% of the work is outside, so it really is a safe undertaking during social distancing. Our re-design of the Solarize model offers both consumers and industry partners more flexibility to get to the best solutions and best prices on a customer-by-customer basis.
There are no free panels. The utilities are not “paying you” to go solar. There is one simple federal tax rebate. We can explain all of that – without a sales pitch. Viridiant is a mission-driven non-profit that has led the charge for cleaner, greener building in Virginia since 2006. Our experts are always available to explain the technology, financing options, installation process, calculating your ROI, and logistics of solar, insulation, HVAC, water heaters, appliances, electric vehicles, and more. If you want to lower costs, improve indoor air quality and comfort, or reduce your carbon footprint, we’re here to help you make the most cost-effective choices.
Here’s my family’s solar story. We’ve had solar panels on the roof of our house a little more than 3 years now, and the only problem we’ve ever had is with my router dropping its connection with the equipment. Meantime, the panels have produced over 28,250 kilowatthours of electricity. At roughly 11 cents per kilowatthour, that’s $3080. After the federal tax credit, we paid $10,400 for this 6KW array (20 panels). Using the simple payback method, we’re in the clear in around 10 years (where else are you going to get a guaranteed 10% return on an investment?). But since this array is rolled into my mortgage (we paid for them as part of a rehab loan), I look at it from a cashflow point of view: I pay about $53/month to have the array there. It makes an average $68/month. I call that making money – from day one. If you’re considering refinancing your mortgage, this could be as good a deal for you.
So what makes a good solar site? First, it’s sunshine. Lots of sunshine. The area should be unshaded most of the day. And if it’s a roof, it should be facing generally south. You want your solar panels to produce as much electricity as possible. They produce the most when the sun’s rays hit them straight on. You also should have a roof that’s in very good shape. You don’t want to install a solar array on shingles that need replacing in less than 10 years.
But you don’t have to figure all of this out on your own. Just reach out to us and we’ll save you hours of research. Not every home has a good site for solar panels and that’s why we encourage everyone to get a home energy inspection as part of the process.
Join us for our webinars on July 23 – or call/email any time.

Virginia Residential Energy Code Field Study Report Released!
The U.S. Department of Energy (DOE) Building Energy Codes Program is conducting a series of research studies investigating building energy code implementation to assist states in measuring energy code compliance and to identify areas of focus for future education & training initiatives.
Southeast Energy Efficiency Alliance (SEEA) led the initiative in Virginia and provided funding for Viridiant to perform a field study in 2017-2018 to assess how well the residential energy code was being implemented across Virginia in new construction single family buildings. Following Viridiant’s data collection and analysis by the Pacific Northwest National Laboratory (PNNL), the Baseline Report was released in October 2019. Key findings include:
- Significant energy and cost savings potential exist through increased compliance with targeted measures. Potential statewide annual energy savings are 150,752 MMBtu, which equates to nearly $3 million in cost savings, and emission reductions of nearly 75,000 MT CO2e. Over a 30-year period, these impacts grow to 70 MMBtu, $1.3 billion, and over 34 million CO2e in avoided emissions.
- Duct leakage and envelope air leakage measures showed the greatest potential for energy savings.
- To achieve potential energy savings focus should be applied to energy code compliance-improvement programs including educational, training, and outreach initiatives.
Based on the results of the study, SEEA provided funding for Viridiant to lead energy code trainings across Virginia. These trainings are intended to provide code officials, builders, architects, and subcontractors with a better understanding of compliance with the targeted energy code measures and how to meet 2015 energy code changes.

Habitat for Humanity Volunteer Day with DMME
Viridiant staff recently visited a single-family home under renovation by Richmond Metropolitan Habitat for Humanity and were joined by volunteers from the Virginia Department of Mines, Minerals, and Energy (DMME). The home is a 1,200 square foot cape-cod built in 1969 and located just outside the Randolph neighborhood in Richmond, VA. Like many Habitat homes, it is pursuing EarthCraft certification.
During the volunteer day, Viridiant’s Executive Director KC Bleile talked about the unique partnership between Viridiant and Habitat for Humanity as well as the history behind the EarthCraft program and its introduction into Virginia. Viridiant Technical Advisor Bill Riggs discussed the requirements associated with meeting the EarthCraft certification, HERS modeling, and the quality assurance provided through the inspection process. Additionally, blower door testing was conducted at the home to show the method for capturing envelope leakage and provide a first-hand demonstration to volunteers. This Habitat home has undergone extensive renovations: completely gutting the interior; re-insulating; installing brand new mechanical equipment, appliances, and finishes. These improvements will result in a much more comfortable, healthy, and energy-efficient home.
The benefits of green construction are especially apparent in affordable housing. That’s why Habitat for Humanity and other nonprofits partner with Viridiant. For families fighting their way out of poverty, energy-efficient homes represent a major step toward their American dream. Every gift to Viridiant pushes that dream forward, helping us touch more buildings, educate more industry professionals, and advocate for high performance construction. Whatever the amount, charitable contributions make our services more affordable, fuel research, and drive educational outreach. We hope you’ll stay involved in our vital work and consider making a tax-deductible gift.
House of Pressure
Developed by EarthCraft Technical Advisor Anthony Cox, the House of Pressure is a nationally recognized prop used to visually demonstrate home performance testing using pressure diagnostics. It’s a useful tool to show stack effect and the movement of pollutants through homes. Attendees of our lecture on Oct. 11, 2018, Managing HVAC in High Performance Buildings, had the opportunity to see the House of Pressure first-hand. Click the video below to see a full demo:
