How do we reduce our greenhouse gas emissions from buildings?
Buildings accounts for approximately 19% of Duluth’s greenhouse gas emissions. To reduce those emissions, we need to make our buildings more energy efficient and fueled by clean and efficient energy.
What are the challenges of our current buildings?
It is important to recognize the complexities around our buildings if we are to build an equitable and sustainable path forward.
Powered by fossil fuels
Creates health risks
Contributes to inequity
Costly to heat
What could a smarter building system look like?
Equitable and sustainable buildings in Duluth could look like:
Fueled by clean energy
Our buildings are energy efficient and fueled by clean and renewable energy.
We have a thriving set of local businesses and jobs related to retrofitting, energy efficiency, solar manufacturing and installation, heating and cooling, and turning local materials into building products
Healthier and more comfortable
Our homes and buildings are healthier and more comfortable because they are meet higher efficiency standards and use clean energy.
Our buildings and their energy sources are resilient to storms and flooding.
Lower energy bills
We have lower energy bills because we're using renewable energy to power our buildings and weatherized them to make them more efficient and less costly.
All members of our community have access to energy-efficient housing fueled by affordable, community-owned clean energy.
What can we do?
The international carbon experts at Project Drawdown and local experts have named these actions as the most impactful in lowering carbon emissions from our buildings:
Shift Energy Sources
What does this mean in Duluth?
There is a lot happening and we can do more.
Much of Duluth housing stock is old and inefficient. For example in the Lincoln Park neighborhood 65.6% of housing was built before 1939. We need to increase efficiency of old buildings by updating city building codes and providing incentives to weatherize and make homes more efficient. This work can provide good local jobs. Clean energy jobs grew 2.5 times faster than other jobs in Minnesota in 2019 and the largest clean energy employer was in energy efficiency.
One organization working on energy efficiency in Duluth is Ecolibrium3, which provides free or low-cost home energy audits and helps low-income residents to weatherize homes. Both our electric utility, Minnesota Power, and our gas utility, Comfort Systems, have rebates for replacing old inefficient heating systems and appliances. And, there are many local and statewide grant and loan programs to help homeowners and building owners increase efficiency.
Shift energy sources
Older homes are more likely to use fuel oil as a heating source which not only produces pollutants but has many health risks. These resources produce greenhouse gases such as carbon dioxide and methane, as well as other harmful pollutants; pollutants that cause the state of Minnesota to spend $2 billion a year on the health impact of burning coal.
We also need to move our energy sources away from natural gas. Natural gas is often offered as the cleaner alternative to coal. However, burning natural gas produces methane, a greenhouse gas 80 times more harmful to the planet than CO2.
Ultimately shifting to community-owned energy production would allow us more control over where our energy comes from for heating, cooling, and powering our buildings, allowing us to move from oil, gas, and coal to renewables.
While temperatures rise in Duluth due to climate change we need to ensure that we deal with refrigerants effectively and safely. We also need to find ways to move away from fluorinated gases to electrification and renewable energy resources.
