In many countries, energy efficiency standards for buildings have been established, making it mandatory for commercial properties, including retail buildings, to comply with specific energy use targets.

As a retail business owner, it’s essential to be aware of any financial incentives and tax breaks provided by the government for investing in energy-efficient solutions. These incentives can help offset the cost of implementing energy-saving measures, making it advantageous for your business to invest in energy efficiency.

Role of Finance and Real Estate Market

Financial management plays a crucial role in supporting energy efficiency projects. Access to capital and finance is essential for enabling retail energy efficiency projects that would not otherwise be completed². However, many retail energy managers lack even basic relationships with their internal finance teams and less than one-third of retailers have adequate financial management in place².

The real estate market can also impact energy efficiency trends in retail buildings, both directly and indirectly. For instance, as a retail business owner, you may choose a more energy-efficient building due to a lower energy cost or long-term investment potential, driving demand for energy-efficient properties. This demand can influence real estate developers to build more energy-efficient retail spaces.

Additionally, commercial buildings, including retail properties, may experience a shift in energy demand, partially driven by evolving societal norms and work-from-home policies³. As telework increases and commercial buildings experience reduced occupancy, retail spaces may need to adapt their energy usage patterns to match these changes.
