Energy Use in Buildings
The energy used in commercial buildings is responsible for 30% of Saint Paul’s total emissions, while residential buildings account for about 27%. Two-thirds (2/3)of the 120,000+ residential units in Saint Paul are in 1-4 unit properties, while the remaining one-third are in multifamily (5+ units) buildings. For the purposes of energy use, these multi-family buildings are considered "commercial."
The cost of energy impacts Saint Paul residents differently. The percentage of income that households spend on energy is called energy burden, and some residents have a significantly larger energy burden than others. The Saint Paul Climate Action & Resilience Plan calls for reducing the energy burden on every household to no more than 4%.
One of the best first steps Saint Paul residents can take to reduce energy bills and cut emissions is to schedule a visit from the Xcel Energy Home Energy Squad. The Home Energy Squad will evaluate your home for energy-saving improvements, provide recommendations, and supply residents with information about rebates from Xcel Energy. And while there, they will Install energy-saving materials such as LED lightbulbs, door and attic hatch weather stripping, programmable thermostat, and high-efficiency water fixtures.
For commercial buildings, better building management and increased energy awareness can help reduce energy usage, thereby also reducing energy costs and greenhouse gas emissions. Xcel Energy also has multiple programs designed to help commercial and multifamily building owners reduce energy use and save money, including rebates on efficient lighting and equipment and technical support to improve operations.

Attaining carbon neutrality in just over 30 years will require aggressive efforts to reduce overall building energy use 50% through efficiency and conservation and convert energy sources to renewable or carbon-free energy.
RESIDENTIAL TARGETS AND ACTIONS
Residential energy accounts for 19% of Saint Paul’s community-wide emissions. Because Xcel Energy plans to produce 100% carbon-free electricity by 2050, the emissions from residential buildings at that time will come entirely from natural gas consumption for the purposes of space and water heating, as well as cooking.
The most impactful actions to reduce those remaining emissions will be:
- Prevent emissions with the adoption of stricter building energy codes for new development
- Complete deep energy retrofits that include building envelope improvements
- Encourage electrification of natural gas appliances
R-1 Achieve PiE plan Year 1 milestones related to energy efficiency
R-2 Work at the state level to support green residential building energy standards; adopt the stretch building code when it becomes available
R-3 Create a comprehensive deep energy efficiency retrofit program that systematically reaches every 1-4 unit household in the city, beginning simultaneously in high energy use and low-income neighborhoods
R-4 Educate residents about the benefits of replacing heating equipment with air-source heat-pumps, or other efficient electric heating options
R-5 Support opportunities for residents to replace natural gas appliances (e.g., ranges, water heaters, etc.) with electric alternatives; partner with Xcel Energy to explore thermal storage opportunities
R-6 Identify opportunities for thermal grid applications for new developments
R-7 Host a citywide solar resource map on the city website
R-8 Offer a production incentive for residential solar installations
Residential Energy Burden
An estimated 38,000 Saint Paul Households live below 50% of the area median income. A baseline analysis of household income and average energy costs show that 12 census tracts within the city have a median energy burden above 4%, with the highest at 12%. These 12 tracts contain over 10,000 households. The following initiatives are aimed at relieving energy burden among households in the 12 census tracts identified in the PiE plan.
REB-1 Establish an energy burden working group to coordinate outreach actions and resource knowledge among local community entities and trusted leaders REB-2 Develop policy options that incentivize 4D property owners (a classification of properties that receives reduced property tax rates to maintain affordability) to make energy efficiency improvements
REB-3 Help increase low-income access to affordable renewable energy
REB-4 Host community-solar gardens that include low-income participation
REB-5 Offer a higher production incentive to income-qualified households as compared to other households
Major Institutions Targets and Actions
The commercial and industrial sectors make up the greatest share of building emissions. Achieving significant reductions among the city’s largest buildings will be critical to work toward carbon neutrality. Many companies across the country are setting their own greenhouse gas (GHG) reduction goals. By working closely with the largest users in the commercial sector, both the city and the business community can realize the benefits of reducing energy use and GHG emissions. The most impactful actions in the commercial sectors are:
- Green building standards for new buildings
- Efficient operation of existing buildings
- Building energy retrofits
MI-1 Secure institutional commitments to achieve carbon neutrality by 2050 in the next two years; following the leadership of Macalester College (carbon neutral by 2025) and University of St. Thomas (carbon neutral by 2035); involve student leaders
MI-2 Explore feasibility and impact of energy benchmarking requirement
MI-3 Support institutions in assessing readiness for renewable energy and investing in renewable subscriptions and/or local renewable installations.
MI-4 Implement additional outreach with local partners to increase participation in available programmatic financing options
MI-5 Implement an energy challenge competition to motivate institutional partners
Multifamily and Large Commercial
Multifamily and large commercial are the next largest users of building energy. Of the more than 100,000 housing units in Saint Paul, approximately one-third are multifamily (5+ units). Other buildings classified as commercial properties include a wide range of use types. Of those over 25,000 square feet, the largest use category are properties classified as generic commercial, such as offices and retail. The different use types pose a range of challenges in addressing energy consumption and program delivery. Better building management and increased energy awareness can help minimize many of those challenges.
