For years, sustainable building design focused mostly on reducing energy use. Efficiency remains the foundation of building decarbonization, lower utility costs, and stronger long-term performance. But as energy systems evolve, efficiency alone is no longer the whole strategy.
Today, building owners are being asked to think not only about how much energy a building uses, but also when and how it uses it.
Growing electricity demand across buildings, transportation, manufacturing, and digital infrastructure is placing new demands on the electric grid. As utilities and regulators work to maintain reliability while supporting electrification, building owners are paying closer attention to when energy is used, how much demand buildings place on the grid, and whether buildings can respond during high-cost or high-stress periods.
Energy flexibility refers to a building's ability to adjust when and how it uses energy in response to grid conditions, utility pricing, or operational needs.
The buildings that perform best in the next decade will not simply use less energy. They will use energy more intelligently.
As a result, states are trying to solve several problems at once: rising electricity demand, grid reliability, electrification, energy affordability, and local economic development. That is why policies around demand response, community energy, virtual net metering, distributed energy resources, and storage are gaining attention.
Buildings consume about 75% of U.S. electricity and 40% of total U.S. energy use, so even small operational changes can affect peak demand, utility costs, and grid reliability. As more buildings electrify, states need ways to manage demand without relying only on new power plants or major grid upgrades.
That is why policies are increasingly focused on when buildings use energy, not just how much they use. For example, California’s Load Management Standards encourage customers to shift electricity use away from times when power is more expensive and toward times when it is cheaper and cleaner.
The policy language can get technical, but the basic ideas are fairly practical.
Demand response allows a building to reduce or shift electricity use during times of grid stress or high prices. This is often in exchange for a bill credit, rate discount, or other compensation. In practice, that might mean pre-cooling a building before a peak period, adjusting HVAC setpoints for a short window, or shifting certain equipment schedules.
Virtual net metering and community energy create another pathway. Virtual net metering allows customers to receive bill credits from an off-site energy project, which is a key structure for community solar. This matters for real estate because not every building has the capacity for on-site solar. A shared off-site project can make clean energy participation more realistic for more properties.
Distributed energy resources are energy resources located close to where electricity is used rather than at a large central power plant. For buildings, that can include onsite solar, battery storage, EV charging, smart controls, and other systems that help manage energy use. For owners, distributed energy resources create more ways to generate, store, reduce, or shift energy as utility programs and grid needs evolve.
Energy flexibility turns a utility bill into an operating strategy.
For owners, the clearest opportunity is cost management. Flexible buildings can reduce peak demand, shift energy use away from expensive periods, and participate in incentive programs where available. Electric utility costs are shaped by a site’s load, demand profile, and rate structure, which means better control over energy timing can directly support operating cost management.
Flexibility also supports resilience and carbon reduction. Battery storage, controls, and load management can help buildings operate more strategically during stress events. With extreme weather events becoming more common and intense in the U.S., this is an increasingly important consideration. At the same time, they can help owners move demand away from higher-emission grid hours of energy, reduce reliance on fossil fuels, and support long-term decarbonization.
For portfolio owners, this becomes even more valuable. Instead of treating each building as a one-off utility problem, owners can compare flexibility opportunities across multiple assets and prioritize the improvements with the strongest financial and sustainability return.
That portfolio view points to a bigger shift: buildings are no longer just passive energy consumers. With connected systems, they can become active participants in grid operations while supporting cost and environmental savings. The U.S. Department of Energy has set a national goal to triple energy efficiency and demand flexibility in buildings by 2030.
Understanding where these opportunities exist often requires a deeper look at building systems, operational patterns, and energy consumption. This is where tools such as energy modeling and engineering assessments can help owners evaluate flexibility opportunities before making capital investments.
Smart controls can adjust HVAC based on occupancy, weather, utility signals, and peak demand. Building automation systems can coordinate lighting, ventilation, heating, cooling, and plug loads. Batteries can store cheaper or cleaner electricity for later use.
Ohio is part of this national trend. Across the country, states are looking for ways to add capacity, improve reliability, reduce grid congestion, and move toward a more flexible, distributed grid.
Ohio has already taken steps in that direction. House Bill 15 updated the state’s competitive retail electric service law and includes provisions related to new generation, energy storage, behind-the-meter generation, grid-enhancing technologies, and distribution system planning.
Ohio is also considering a separate community energy program, which would create a pilot program for shared energy projects. That bill has passed the House and been introduced in the Senate, so it should be treated as an active policy trend rather than an enacted program.
While most owners will never need to follow the details of individual energy bills or legislative proposals, these efforts signal a broader shift toward policies that support energy flexibility, distributed energy resources, and greater customer participation in energy management.
Ohio’s energy policy environment is moving toward more flexible and customer-connected energy strategies. Similar efforts are underway in states across the country as utilities, regulators, and building owners look for new ways to balance reliability, affordability, and sustainability. Owners who understand their building loads and energy options will be better prepared as new programs and incentives emerge.
Owners do not need to wait for every policy detail to settle before planning for energy flexibility. The practical first step is understanding how a building uses energy today, where demand can be reduced or shifted, and which systems can support future energy changes.
Building decarbonization will continue to rely on efficiency, but efficiency alone is no longer the entire conversation. As energy systems evolve, owners who understand how their buildings consume, store, and respond to energy will be better positioned to manage costs, support resilience, and pursue long-term sustainability goals.
