Major Ohio cities aim to cut building emissions with voluntary program

This story was originally published by Energy News Network.

A federal grant will help four of Ohio’s largest cities collaborate on new voluntary building performance standards and a resource hub to help commercial building owners save energy and cut emissions.

Cincinnati, Cleveland, Columbus, and Dayton will use $10 million in Inflation Reduction Act funding to establish the Ohio High Performance Building Hub, which will connect building owners with technical guidance, financing solutions, incentives, training, and other support.

Clean energy advocates and city sustainability leaders hope the program will offer a new path forward in a state where buildings account for about one-fourth of greenhouse gas emissions but state lawmakers have gutted mandatory energy efficiency measures. The state ranked 44^th in a recent state energy efficiency policy report card.

“All four of those cities have ambitious climate goals, and addressing existing buildings is a crucial part of that,” said Nat Ziegler, a program manager with Power a Clean Future Ohio, which is a partner on the grant. They expect lessons learned from the work and the hub can eventually help other cities and towns in Ohio and across the Midwest.

Buildings account for a significant share of greenhouse gas emissions in the four cities participating in the grant: greater than 60% for Cincinnati and from 50% to 55% for Cleveland, Columbus, and Dayton. The new program will specifically target emissions from more than 421 million square feet of commercial building space among the four cities.

“This is a great way to really jump-start a lot of that work,” said Erin Beck, assistant director for Sustainable Columbus.

The hub could help building owners navigate funding under the Inflation Reduction Act, as well as through bonds issued by the Ohio Air Quality Development Agency or local port authorities, or lending from green banks or more traditional financial institutions.

Standards vs. codes

Existing building energy codes ​“apply primarily to new construction and major renovations, which is great. But most buildings already exist, right?” said Amanda Webb, an assistant professor of architectural engineering at the University of Cincinnati, which was the lead recipient of an earlier $2.9 million grant focused on developing technical guidance for the voluntary standards.

Work under both Department of Energy grants focuses on ​“coming up with a way to help really deliver the benefits of energy efficiency to existing buildings at scale,” Webb said.

The standards will differ from more general guidelines such as the U.S. Green Building Council’s LEED program, which largely emphasize new construction and a broader range of sustainability measures than energy use and emissions.

Cities will use the technical guidance from the work by Webb’s group and results from outreach to develop standards, rather than codes. The difference is codes are mandatory, with penalties for violations, whereas standards are not.

“The approach that we’re taking with this is definitely much more of a carrot approach” than a stick, said Robert McCracken, who heads up energy management for the Office of Environment & Sustainability in Cincinnati, which is the lead partner on the project.

The reasons are largely legal, as well as political. Over the past decade, leadership in the Ohio General Assembly has generally opposed imposing requirements to cut pollution, and a bill for utilities to provide voluntary energy efficiency programs still has not passed.

As a legal matter, cities generally can’t adopt building codes stricter than those established by the Ohio Board of Building Standards. However, the board doesn’t have authority to set requirements for benchmarking emissions or performance standards for existing buildings. The cities’ grant application said the board confirmed that a delegation of authority won’t be needed, as long as they don’t adopt new construction codes.

Energy efficiency provides its own incentives for building owners, because ​“it saves money,” said Oliver Kroner, who heads up Cincinnati’s Office of Environment & Sustainability. ​“People are generally aligned with the [city’s] climate commitments. But there’s sometimes the gap with what you want to do and how to get there.”

Lower costs for building owners can also let them charge lower rents, which can attract tenants. ​“We frequently receive inquiries from companies who are considering relocating, and they’re interested in the climate effort here,” Kroner said.

Ziegler said many of their organization’s 50 local government members also have shown interest in getting help for cutting building emissions. The independent hub to be set up under the new grant will really help building owners with the ​“nuts and bolts” for meeting their city’s building performance standards, they said.

Columbus is the only one of the four cities with a benchmarking policy right now, and the plan calls for the others to adopt their own versions as well. Benchmarking will be key for letting the cities track progress in reducing energy use. Based on existing commercial building stock in each city, the team members estimate cutting energy use by 45% by 2050, the grant application materials said.

Beck said the Columbus benchmarking program has ​“been very successful,” noting the city has worked with building owners to help them comply. Audits done as part of the process have also identified ​“low-hanging fruit” for adding energy efficiency through LED lighting, thermostat adjustments, and so on, she noted.

Equity issues

Equity concerns also factor into the choice of standards versus codes. Businesses in historically disinvested communities already face a variety of financial and other challenges.

“We want this to be a benefit rather than yet another burden that’s imposed on them,” Ziegler said.

Webb’s team is also exploring how building performance standards could be tailored up front to address concerns about affordability. Possibilities could include a metric to reflect greater equity needs or measures to ensure tenants as well as owners benefit from savings.

“We have other grants that are focused on workforce development,” Kroner said, adding his hope that many people from underserved communities will be able to work in jobs to help buildings meet building performance standards once they’re adopted.

As work by Webb’s group continues, the four cities and others will gear up for outreach efforts and other work so they’re ready to adopt standards. ​“There’s going to be a lot of education and outreach in the beginning,” McCracken said.
