Report, tools seek to boost building efficiency

Utilities have a vested interest in working with homeowners and businesses to accurately estimate and control energy costs. It is not only good for load management goals, it is also good for the local economy. A new report from Rocky Mountain Institute  You are leaving WAPA.gov. (RMI) and tools being developed by the National Renewable Energy Laboratory (NREL) can help utilities and cities move toward a more efficient building stock.

Changing real estate conversation
According to the online real estate platform Redfin, You are leaving WAPA.gov. energy bills can add as much as 40 percent to annual housing costs in some parts of the country. An MPG for Homes: Driving Visible Value for Home Energy Performance in Real Estate, the RMI report, makes the argument for incorporating energy use data into the total cost of homeownership calculations.

The authors emphasize, however, that making home energy use data more accessible is part of a greater vision. True market transformation will require a change in both homebuyer behavior and policies and approaches across several interconnected industries. The real estate, finance, home improvement and—yes—utility industry would all play a part and could all benefit in the long run from improving home performance metrics and making the data more transparent and accessible to homeowners.

RMI notes that the “green real estate” movement is already starting to catch on with online real estate portals featuring home energy scores on property listings. Partnerships between the Zillow Group You are leaving WAPA.gov. and UtilityScore, You are leaving WAPA.gov. Estately You are leaving WAPA.gov. and Clearly Energy and Redfin and Tendril You are leaving WAPA.gov. are aiming to make home energy scores a bigger consideration in buying decisions.

Recent home purchases drove 26 percent of home renovations in 2015, and preparation for resale led to 13 percent of renovations, according to Houzz and Home: Overview of Renovation. You are leaving WAPA.gov. Moreover, 67 percent of study respondents cited improving energy efficiency as an important reason for making a renovation. Clearly, renovation projects offer utilities an opportunity to promote energy-efficiency measures and programs to a receptive audience. Establishing relationships with housing professionals in the community could pay off for utility program managers in a big way.

Tools analyze home, infrastructure projects
Once you connect with customers who are interested in making energy-efficiency improvements, the next challenge is determining what upgrades will save them the most money and energy. The ResStock analysis tool from NREL provides detailed information on the technical and economic potential of residential energy-efficiency improvements and packages for 48 U.S. states.

By combining large data sources and statistical sampling with detailed building simulations, the program achieves unprecedented accuracy in modeling the diversity of the single-family housing stock. The ResStock software leverages DOE’s open-source building energy modeling platforms OpenStudio® You are leaving WAPA.gov.  and EnergyPlus You are leaving WAPA.gov. so you won’t need a supercomputer to run the program. Contact NREL to find out more.

On a larger scale, NREL’s Energy Systems Integration Facility is working on a demonstration project that is developing a buildings and district energy modeling tool, URBANopt. The demonstration integrates URBANopt with grid modeling software, OpenDSS, to analyze the projected dynamic energy consumption of a planned 382-acre mixed-use development. The Denver, Colorado, site includes corporate office space, retail space, multifamily dwellings, a hotel and parking and street lighting. This project will result in several tools that others can use to replicate this project across the country, including an enhanced version of URBANopt and a developer’s handbook.

WAPA’s Renewable Resources Program co-sponsors workshop on tough solar-program challenges

June 7-8, 2017
Golden, Colorado

What is the toughest challenge for an electric cooperative or public power utility in planning for community solar? Many utilities say it is solar resource procurement; for others, the top challenge would be pricing that works for both the utility and the customer, and turning that into a program offer. The Community Solar Value Project You are leaving WAPA.gov. (CSVP) and WAPA’s Renewable Resources Program have heard these frequently cited concerns, and they are responding with a new, one-and-a-half day workshop, Community Solar Procurements, Programs and Pricing, on June 7-8 at the WAPA Electric Power Training Center in Golden, Colorado. Registration You are leaving WAPA.gov. is free and targeted at utilities in the West, whether they are in states like Colorado that have guiding community solar legislation or states in which community solar is an option that requires utility leadership and innovation.

According to Jill Cliburn, program manager for CSVP, this event will be the culmination of a two-and-a-half-year investigation into utilities’ best practices and innovations in community solar. Community solar, or community shared solar, describes a range of programs that allow customers to share, usually by a per-kilowatt-hour subscription or by leasing or buying panels, in a relatively large solar project, regardless of their ability to host a typical rooftop solar system. Projects are currently in place in 29 states, with the total market expected to grow by 20 percent or more annually.

This workshop will feature speakers from utility-led community solar programs, such as those at Sacramento Municipal Utility District You are leaving WAPA.gov. and Pedernales Electric Cooperative. You are leaving WAPA.gov. Thought leaders from CSVP’s own expert team, Navigant Consulting, You are leaving WAPA.gov. the Regulatory Assistance Project You are leaving WAPA.gov. and Rocky Mountain Institute You are leaving WAPA.gov. (RMI) will also speak. RMI’s successful Shine Project recently demonstrated ways to dramatically lower local solar procurement costs, whether for community solar programs or other utility needs.

“We’re also making time for participants to share their own unique challenges and solutions, so everyone will leave the workshop with actionable notes and resources,” Cliburn said.

Working with a utility forum group of about 10 utilities in the West, CSVP has put emphasis on practical solutions. For example, the project’s approach to pricing begins with streamlined utility-side economic analysis, but takes into account the market-target price required for program success. CSVP also has introduced new ways to package community solar with other utility program offers. And the project has published easy-to-use resource guides and checklists to help keep other tasks, from market research to completing the project RFP and procurement, on track and on budget.

Community Solar Procurements, Programs and Pricing begins at 3:00 p.m. (MDT) on Wednesday June 7, with a “lightning round” of community solar best-practice presentations and a quick tour of WAPA’s grid simulator, followed by a cash-bar networking reception. On Thursday June 8, the workshop convenes from 8 a.m. to 5 p.m., with lunch and breaks included. There is no cost for utility representatives to participate in this workshop, thanks to CSVP sponsorship by the U.S. Department of Energy SunShot Initiative and Solar Market Pathways Program and workshop co-sponsorship from the WAPA Renewable Resources Program and Extensible Energy, LLC, You are leaving WAPA.gov. the prime contractor for CSVP. Participants only cover travel and hotel costs and incidentals. For more information, see the registration website or contact workshop coordinator Nicole Enright.

Fort Collins forges ahead on climate goals

Throughout the nation, municipalities are showing leadership in addressing climate change, and Fort Collins, Colorado, is leading the leaders. The city recently revised its climate action goals to reduce its total greenhouse gas emissions 20 percent by 2020 and 80 percent by 2030 across all sectors relative to 2005 levels.

An article in the Rocky Mountain Institute (RMI) Outlet Redirecting to a non-government site notes that the 2030 target is 20 years sooner than the “80 by ‘50” goal other leading cities have set, making it among the most ambitious of any city in the world. RMI is among the many partners the Fort Collins City Council engaged to assess the costs and benefits to the community of accelerating the city’s greenhouse gas emissions goals. The partnership includes community leaders, local businesses, citizen advisory groups, the communities’ generation and distribution utilities and research institutes.

Investment required
Led by city government and Fort Collins Utilities,Redirecting to a non-government site the partnership has discussed, analyzed and reviewed approaches to achieving the goals. The forward-looking plan lays the groundwork to stimulate hundreds of millions of dollars of new investments in efficiency and renewable resources in the years ahead. The upfront capital requirements will be high, but RMI estimates that the investments in carbon reduction will begin producing real financial benefits to the community close to 2030.

In addition to investing in infrastructure upgrades and clean central generation, the community will need to improve its building stock as well. The targets the city has identified to achieve its goals include:

  • Reduce building emissions by 40 percent through greater efficiency and distributed solar adoption
  • Reduce carbon emissions from the utility electricity system by 79 percent from 2005 levels
  • Reduce transportation carbon emissions by 57 percent from 2005 levels
  • Create a zero-waste community

Utility tackles challenge
Increasing the efficiency of the building stock poses a special challenge, as buildings are responsible for 53 percent of emissions and participation in retrofit programs is often low. The city’s municipal utility plays a central role in encouraging citizens to invest in efficiency for homes and commercial facilities. A recently approved update to the utility’s on-bill financing program allows unprecedented access and flexibility for financing efficiency. The plan gives customers the ability to allocate costs between tenant and landlord, and includes longer financing terms that match the life of the upgrades, lower interest rates and an easier approval process.

The integrated utility services model Redirecting to a non-government site Fort Collins Utilities developed with RMI’s support could, if adopted, do even more to promote building efficiency. It would allow the utility to centrally deliver energy services; such as efficiency, distributed renewables and value-added services; at scales that will achieve cost savings and high-quality service, and be paid for on customers’ electricity bills. This approach offers an innovative model for utilities seeking to grow their business by diversifying their services to customers.

Long journey to sustainability
The new goals are part of continuing process that has engaged the city and its partners for more than 15 years.

The Fort Collins City Council passed a resolution in 1999, committing the city to reducing its greenhouse gas emissions significantly by 2010. The landmark year of 2007 saw the formation of the city’s Climate Task Force and the implementation of FortZED, funded by an $11 million federal grant. The project created a zero-energy district in Fort Collins’ downtown business district and the Colorado State University Redirecting to a non-government site campus. It also launched a dialogue between the university, the utility and the city that continues today, and led directly to the city council’s vote to adopt the historic new goals.

The process has not been smooth or easy, but the city has already made significant progress. By continuing its methodical, inclusive and thoughtful approach, Fort Collins is showing how even a town of 150,000 can make big strides in fighting climate change.

Gamifying Energy Use: Observed Trends From SXSW Interactive

When it comes to energy and the environment, most people want to do the right thing. But how many people actually contribute to improving energy use and environmental impact is another story. Ben Holland of Rocky Mountain Institute knows this better than most. As project manager for RMI’s Project Get Ready, Holland works with cities and industry leaders to promote electric vehicle integration and adoption.

He recently gave a presentation on his work at South By Southwest (SXSW) Interactive, the annual arts and technology conference in Austin, Texas. Initially, Holland was unsure about discussing the seemingly unrelated topic of observed barriers to electric vehicle adoption. But it turns out that the SXSW crowd is ahead of the curve on the subjects of environment and energy use.

“Gamification” and “Big Data” were two buzzwords frequently heard at SXSW earlier this month. The two closely related concepts, when combined, could have significant implications for energy use. Applying principals of gaming to non-game applications may encourage people to change their behavior. Mobile app developers have had great success doing this by incorporating location-based awareness data into their products. What if you could do something similar for energy? Read more.
