PORTAGE, Ind. - A Portage woman couldn't be more grateful for the Weatherization Assistance program that helps keep her home cooler in the summer and warmer in the winter. The 2009 Little Calumet River flood destroyed the insulation in the crawl space of Cindy Markley's home.
"The insulation that's under my kitchen floor is in the crawl space and we had to take all that out. Then my husband passed away and we never got it back in. So, I was having to use a space heater in the kitchen and it was just really cold all the time in the winter."
Being on disability and having a fixed income made the thought of repairs seem impossible until a cousin helped Markley apply for a program through Northwest Indiana Community Action to get her home weatherized.
Weatherization experts inspected Markley's house, cleaned the furnace and installed insulation, reducing her energy bills by 60 percent. Markley says she sent a thank-you card, and appreciates the opportunity to say thank you again to Northwest Indiana Community Action.
"I really hope they get the recognition that they deserve because, if they knew how they touched people's lives that weren't able to, or even fathom how they could, fix something like this. You know, especially like as a woman who doesn't know how or doesn't have the money."
Statewide across Indiana in the last two years, close to 11,000 low-income homes have been treated by community action programs, touching the lives of close to 25,000 people. Through the weatherization program since 2010, about 9,200 homes have had insulation installed and over 7,600 faulty furnaces, water heaters and stoves repaired or replaced.

After a renovation project next year, the primates at St. Paul’s Como Park Zoo will reside in one of the first net-zero city-owned buildings.
Retrofitting several buildings at the zoo and the adjacent St. Paul Conservatory is part of a decarbonization initiative by the city to reach carbon neutrality for civic buildings by 2030.
That goal is one of many in St. Paul’s 2019 climate action and resilience plan, which outlines strategies and goals for carbon reduction in private and city-owned buildings and transportation, combined with the promotion of green infrastructure, water conservation and improved waste management.
The goal: “Achieve carbon neutrality in municipal building operations by 2030.”
St. Paul owns more than 150 buildings containing over 2.3 million square feet of space. The building portfolio includes police stations, community and recreation centers, libraries, public works and operations facilities.
Buildings represent around 40% of carbon emissions nationally. Many cities, like St. Paul, have had programs for years dedicated to improving energy efficiency and adding solar to their buildings. As cities have begun to encourage, require and incentivize private building owners to become more efficient, civic leaders believe they need to serve as an example. St. Paul’s climate action plan suggests the city “inspire through municipal leadership.”
According to Abby Finis, a consultant who has written several climate action plans for Minnesota cities, cities have great opportunities to reduce greenhouse gases from their buildings.
“I think from an operations standpoint, cities are now in control of their facilities and their fleets, and there’s low-hanging fruit in both, but that’s not to say either is easy,” said Finis, who consults with St. Paul as well as Fresh Energy, publisher of the Energy News Network. “Building benchmarking, efficiency measures and decarbonization plans are good strategies.”
Should St. Paul decarbonize all city-owned buildings, it will have achieved perhaps the easiest part of its climate action plan, with city properties representing just 2% of emissions. By 2050, the plan calls for decarbonizing all buildings.
The strategy
St. Paul’s climate action plan provides a game plan of sorts for the city’s built infrastructure, with 11 recommendations guiding everything from cost analysis to building materials. In many ways, the city is simply building on its legacy of sustainability.
St. Paul energy coordinator Cecilia Govrik said from 2009 to 2018, the city’s Green Revolving Loan Fund saw 629 projects completed, saving the city $1.6 million in energy costs.
Employing efficiency measures in existing and new buildings has been St. Paul’s chief strategy for carbon reduction, but that will not get the city to net zero. St. Paul chief resilience officer Russ Stark said new and under-consctruction city buildings focus on combining efficiency with heating electrification to move the city away from natural gas.
An 25,000-square-foot community center under construction in the North End features ground-source heating and cooling combined with rooftop solar. A new fire station features an electric truck, Stark said. Lighting projects at recreation centers and the central library, along with a new HVAC at the police department’s headquarters, will also drive down emissions.
Stark suggested efficiency projects may continue, but will likely focus on LEDs and building automation rather than insulation because of the cost. Meanwhile, a decarbonization strategy could involve installing geothermal heating and cooling in larger buildings and air source heat pumps in smaller ones.
Heat pump technology could be one approach to heating electrification. However, Stark wonders whether city buildings will still need backup heating sources for subzero temperature days, a requirement adding equipment and cost.
Next year, St. Paul will take another step toward electrification by spending $4.4 million on installing a geothermal system in the zoo’s Primates Building. He said the zoo and conservatory account for roughly 20% of the city’s energy consumption, making them obvious targets for efficiency investments.
“We’re certainly really focused on the Como campus right now because so much of our building portfolio energy use is out there,” Stark said. “It’s a campus, so theoretically, there’s a way to tackle a lot in one in one spot. There’s the opportunity to use less energy and electrify those buildings.”
Como Park Zoo and Conservatory Director Michelle Furrer said the campus has an inefficient central plant built in the 1940s that produces steam heat for hot water. A feasibility study found geothermal heating and cooling systems to be a good option, with an approach of installing them in one building at a time. After completing the primate center, Furrer and the city hope to raise nearly $8 million for installing geothermal in the visitors center and the main zoo building.
Retrofitting all the zoo and conservatory’s 19 buildings will take years. Other efficiency projects involving LEDs and building management systems will help with decarbonization efforts.
“We have a unique opportunity at Como Park Zoo and Conservatory to not only talk the talk but walk the walk in what we can do,” Furrer said. “We get almost two million visitors a year. We have a great opportunity not only to do the work but also to showcase it.”
The results (so far)
Until last year, St. Paul had carbon emissions data for the entire city, but not specifically from city-owned buildings. Govrik, who started her job with the city in November 2022, spent part of her first year gathering building emission data to determine the city’s impact.
Since St. Paul passed the climate change plan, carbon emissions have declined significantly, from 21,257 metric tons of CO in 2019 to 15,800 metric tons in 2022, Govrik said. That’s a nearly 26% decrease. Emissions have been coming down for years, and she said the city should be on track to decarbonize all its buildings by 2030.
“This is really the first time we’ve had actual statistics to show how much progress we’ve made so far,” she said. “We can say we’re getting close to halfway to our goal, knowing that our end date for that carbon neutrality goal is 2030. We’re making good progress, but we still have a long way to go.”
An example of the St. Paul’s decarbonization work came in 2022, when the city decreased electricity use in buildings by 519,000 kilowatt hours and by 3,100 therms of natural gas through efficiency and LEDs projects. A year later, St. Paul used Xcel Energy’s One-Stop Efficiency Shop, managed by the Center for Energy and Environment, to upgrade lighting at seven community and recreation centers, saving 254,000 kWh.
Although St. Paul has made great strides in reducing energy use in buildings through lighting retrofits, most of St. Paul’s carbon reduction can be attributed to Xcel Energy’s transition to clean energy. More than 60% of the utility’s electricity comes from carbon-free resources, primarily nuclear and wind energy.
The challenges
Since 2015, the city’s efficiency measures have decreased electricity consumption by 47%, but only reduced natural gas consumption by 5%.
That’s in part because city-owned buildings have a wide range of ages, sizes and uses, making a one-size-fits-all approach unworkable. “There’s so much of this that has to be done at the building level because of the unique aspects of each building,” Govrik said.
Another issue is that the city hall and annex and the central police station receive heat and cooling from District Energy, which primarily serves downtown. District Energy burns waste wood for electricity in a process involving fossil fuels.
“We’ll need improvements from District Energy,” Govrik said.
Getting the city out of the habit of buying familiar replacements when HVAC systems break down will also require a cultural shift.
The city needs to break “the business as usual of just replacing equipment with the same equipment in a more efficient version,” Govrik said. ‘If we’re replacing gas boilers with more efficient gas boilers, we still have emissions from gas boilers going forward for 15 to 20 years.”
Finally, paying for electrification will not be cheap or easy. The Legislature passed 45 energy bills in 2023 that present funding opportunities for cities, as do the Inflation Reduction Act and other federal legislation. The IRA’s direct pay allows government agencies and nonprofits to receive a 30% to 40% project reimbursement, making clean energy investment for St. Paul more affordable.
“Figuring out the best funding source, grant opportunities and rebates and incentives for every project will be a challenge,” she said.
The next steps
Next year, the city plans to hire a consultant to write a decarbonization plan using a $317,000 federal grant. Govrik said the Municipal Buildings Decarbonization Plan will guide St. Paul’s clean energy initiatives for the next few years.
Since “it isn’t realistic” yet to electrify every city-owned building, staff will identify electrification projects that have the greatest impact on the city’s emissions and can take the greatest advantage of federal funding, she said.
“That plan will identify the most cost-effective pathways for achieving further energy efficiency, electrifying municipal buildings, and integrating more renewable energy into the city’s portfolio,” Govrik said.

Minnesota has about 15 years to achieve its mandate of 100% carbon-free electricity from utilities.
To get there, clean energy voices say the permitting process has to move much faster, and they think legislation would make a difference.
Minnesota's carbon-free standard for 2040 was approved last year.
In this legislative session, lawmakers have followed up with a measure that aims to reduce the timeline for those seeking permits for wind, solar and power grid expansion projects.
Madelyn Smerillo - regional policy manager for the Clean Grid Alliance - said not only would it help with emission targets, but would also provide certainty to developers.
"The developers need to know when they're going to be able to get steel in the ground," said Smerillo. "They need to know when they can start their construction."
Researchers say Minnesota's current permitting process for solar projects has increased from an average of 300 days to nearly 550 days.
Among other things, the bill would remove duplications, and require state agencies to identify and solve problems early in the process.
For those worried about minimizing public engagement, supporters say the new plan doesn't sacrifice the ability for residents to have their say.
Smerillo contended the proposed changes would make it easier for the public to get a better understanding of clean energy development happening in their backyard.
"So they can clearly see," said Smerillo, "these are the projects that get a shorter timeline, these are the projects that have a longer timeline, and these are the requirements that are expected of all of them. "
The bill was drafted with input from nearly 30 stakeholders recommended by state regulators. It's been making its way through committees and could be included in a larger omnibus package.
The Senate version has Republican and Democratic sponsors, hinting at bipartisan support as the measure advances.

Nevada state leaders held a workshop on clean energy home upgrades and discussed how people can leverage available tax credits on solar power, heat pump appliances, and weatherization projects.
State Sen. Dina Neal - D-Las Vegas - said while there are many beneficial federal investments coming to the Silver State that can help Nevadans save on utility bills, she wants to see more work being done to ensure communities of color and low-income households can tap into them.
"Typically in our community we are under-banked, under-loaned," said Neal, "so what are the chances of us getting it anyway? You have to be able to make it reachable for those communities that are already in that situation, meaning they don't have access to capital, they don't have a good credit score."
A study found that majority Black and Hispanic neighborhoods in the U.S. installed 69% and 30% fewer rooftop solar systems respectively, than majority white neighborhoods.
Neal said there are programs making a difference, like NV Energy's Qualified Appliance Replacement program which aims to help limited-income homeowners and renters replace select older, inefficient household appliances with newer, more efficient models.
Nevada Clean Energy Fund Loan Officer and Program Manager Will Pregman said organizations like his are there to help connect Nevadans and contractor businesses with incentive programs.
Pregman said among the biggest challenges in realizing clean energy investments is the high up-front costs.
But for him, it's all about being an efficient energy consumer, which he said saves money down the line.
"So it is about reducing energy usage and making that energy usage more efficient," said Pregman, "and that happens with the clean technology that is incentivized by these renewable rebates and tax credits."
Pregman said they've launched their Residential Energy Upgrade Program, also referred to as RE-UP, which was designed to create affordable financing options for clean energy upgrades and repairs for low or moderate-income Nevadans.
He contended the loans they offer through RE-UP, combined with rebates, taxes credits and other incentives can help Nevadans lower their utility bills.
