Maximizing Energy Savings for Small Businesses

Dollars saved through energy efficiency can directly impact a business’s bottom line and enable them to be more competitive in today's market. Many small businesses reside in commercial buildings smaller than 50,000 ft2, which consume 44% of U.S. commercial building energy use (nearly 3 quadrillion Btu annually). By tapping into a number or resources and financing options, small business owners can save significant amounts of money and energy, increase profits, promote their business, and cut greenhouse gas emissions.

The Benefits

There are three key reasons small business owners should improve the energy efficiency of a building:

Increase Profits

Reduce operating costs and utility bills while increasing potential rental income and the overall property value.


Promote Your Business

Enhance the marketability of your products, services, and brand image, particularly with environmentally-conscientious customers.


Reduce Environmental Impacts

Reduce CO2 emissions while improving customer experience and comfort.

How To Do It

NREL helps small building and small business owners by demystifying the three-step processes and providing tools and resources needed to overcome obstacles to achieving building energy efficiency.


Step 1: Contact a Qualified Energy Auditor/Contractor

To better identify the goals for your building and business, as well as the paths for achieving those goals, it’s always recommended to consult with a qualified energy auditor/contractor to:


Step 2: Make a Business Case

After consulting with a qualified energy auditor/contractor and you are ready to put your business case on paper, focus on:


Step 3: Find More Information

Once your business case is in place, get more information about available programs. Resources include:

  • State and Federal Financial Incentives: The Database of State Incentives for Renewables & Efficiency® (DSIRE) website is a comprehensive source of information on incentives and policies that support renewable energy and energy efficiency in the United States

  • Resources and Case Studies on Energy Efficiency: The U.S. Department of Energy's (DOE's) Better Buildings Initiative hosts a catalogue of resources to support the adoption of energy-saving building technologies that include simple steps to saving energy in commercial buildings

  • Small Business-Specific Resources: NREL's four-page guide helps small businesses understand the energy and non-energy benefits of energy-efficiency investments. These resources also help small businesses know what contractor and auditor qualifications to look for, identify low- and no-cost energy savings opportunities, and understand the decision process for energy-efficiency upgrades

  • Government Guaranteed Financing:
    • SBA's loan programs offer numerous opportunities to finance building energy improvement projects for small businesses
    • U.S. Department of Agriculture (USDA) programs provide funding opportunities for rural small businesses through loans, loan guarantees, and grants.

NREL's Research

A significant amount of work has been done at NREL around making small businesses and buildings more energy efficient.

  • NREL provided industry research and recommendations for Small Buildings and Small Portfolios. NREL worked with the National Trust for Historic Preservations Preservation Green Lab to identify potential approaches and strategic priorities for the DOE Building Technologies Office to explore that support the implementation of high-potential energy efficiency opportunities for the small commercial building sector. A summary of the findings is available.

  • NREL conducted a pilot project, Reducing Transaction Costs and Analysis of Economic Risk, focused on overcoming two barriers to financing energy efficiency upgrades in small buildings: disproportionately high transaction costs and unknown or unacceptable risk. After working with Michigan Saves and Energi Insurance Services, NREL developed technical solutions that provide a quick and easy process to encourage energy efficiency investments while managing risk.

  • Research was conducted to develop Energy Efficiency Measure (EEM) packages for small commercial office buildings that achieve 20% energy savings cost effectively, the results of which are summarized in a simple spreadsheet tool called the Energy Efficiency Measure (EEM) Selection & Cost Evaluation ToolMicrosoft Excel. NREL worked to quantify performance risk and the uncertainty in cash flow associated with EEM packages that are designed and installed correctly. This analysis quantifies the effects of uncontrollable uncertainties that go beyond typical performance guarantees including variations in weather, occupant behavior, fuel escalation rates, and quality of preventative maintenance.

  • NREL provides SUNREL®, an hourly building energy simulation program that aids in the design of small energy-efficient buildings where the loads are dominated by the dynamic interactions between the building's envelope, its environment, and its occupants.
