Housing, Buildings & Development

Housing and buildings can be designed to maximize energy efficiency and reduce the consumption of electricity and natural gas. Emissions come from residential, commercial, and industrial buildings consuming electricity from nonrenewable sources and burning fossil fuels. Designing new buildings and retrofits to maximize efficiency and use of renewable energy sources reduces emissions, saves money, and increases our resilience to changing climate conditions.

Through the CAAP process, Columbia identified three strategic goals for Housing, Buildings & Development:

        1. Increase energy efficiency in residential, commercial and municipal buildings.
        2. Reduce fossil fuel use.
        3. Enhance building resilience.

Climate Change & Our Built Environment

Protecting our Buildings

As the climate continues to change, Columbia communities are likely to face vulnerabilities related to their built environment, especially housing. Rising temperatures and heavier rains will affect homeowners by creating higher energy costs and potential property damage. Learn more about what we can expect. For more information on what our City is doing to increase our resilience visit our CAAP.

  

Climate Change & Our Built Environment

Warmer Temperatures

Climate change is expected to increase air temperatures in Columbia, with summertime highs reaching nearly 104°F, nightly lows staying above 80°F, and 50 days a year over 95 degrees by 2080. Asphalt and other features in the urban environment will only make temperatures warmer in the city due to the urban heat island effect. All this will increase demand for air conditioning, raising energy costs, which will be especially difficult for lower income households to bear. The City already provides energy efficiency incentives with loans and rebates to residential and commercial customers. Going forward, natural shading and passive cooling design, in addition to more insulation and efficient AC equipment, could provide relief from the heat.

Flooding

Columbia is expected to have more frequent heavy rainfall events in the future, which will increase the risk of local flooding to buildings, especially those located in flood zones. Thirty residential structures are located in the flood plain, but about 300 more are in areas at risk of flooding during bigger events that have historically happened every 100 years. The City currently runs a buyout program for homes in the flood plains, as well as home repair and rehabilitation funds to low- and moderate-income families.

  

Energy Efficient Buildings

Energy Use in Our Buildings

The electricity we use in homes and buildings throughout Columbia is the largest source of energy use and GHG emissions. While Columbia Water & Light already have a number of programs to support energy efficiency in our buildings, the City has placed a high priority in creating new incentives and financing mechanisms to ensure everyone in the community has access to resources to reduce energy use through the CAAP.

UNIT
Energy from different sources is measured in different ways—electricity is measured in kWh, natural gas in therms, oil in gallons. We can convert these different measures into a common measure—million British Thermal Units (MMBTU)—to better understand and compare total energy use.

Breaking It Down

Knowing how much energy is used in different parts of the community helps us know where the biggest opportunities to reduce are.  Not surprisingly with the university and associated industries that much of our consumption is in the commercial sector.

Energy Reduction Goals

The City of Columbia has set an energy reduction goal for its own facilities—a 20% reduction by 2025. Achieving this ambitious short term goal will help provide examples for other community partners as they make their own energy use reductions. 

Often called benchmarking, a critical first step in lowering energy intensity is measuring the amount of electricity and natural gas used in our buildings. The City of Columbia has benchmarked and monitored energy usage across 37 of our municipal facilities. Overall, energy use has decreased by 12% over the past 8 years.

Green & Resilient Buildings

Green Buildings

Green building practices are healthier and more resource-efficient models of construction, renovation, operation, maintenance and demolition. Two common certification programs are the US Green Building Council's Leadership in Energy & Design (LEED) and the US Department of Energy's EnergyStar ratings. Columbia has 37 buildings that are either LEED or Energy Star certified since 2008. Eight buildings are currently under evaluation for LEED status.

Certified Green Buildings in Columbia

Columbia has seen a significant increase in the number of new buildings that have been awarded a green building (LEED or Energy Star) certification, up from one in 2008 to 45 by the end of 2018! Check out the data.

  

What are the Lynn Street Cottages?

The City of Columbia’s Housing Programs Division has been working alongside neighborhood and community members to redevelop the block of Garth, Sexton, Oak, and Lynn with affordable housing and improved infrastructure. The project includes the development of eight affordable owner-occupied homes with near net-zero energy usage design and universal design features. The Lynn Cottages development also coincided with the City’s creation of the Columbia Community Land Trust, which will ensure the homes remain affordable, owner-occupied, and well-maintained for generations to come.
