Four Strategies for Decarbonization, Electrification in Commercial Buildings

Written by Bill Kosik

Tap into state efficiency programs to reduce energy consumption of air handling systems.

Learning Objectives:

  • Discover what role commercial buildings have in carbon dioxide emissions and the resulting impact on climate change.
  • Understand how state energy plans are structured and learn about energy-efficiency incentive programs.
  • Get a more in-depth understanding of the different approaches on using technical resources manuals and the energy-efficiency measures.
  • Learn about specific energy-efficiency measures used in incentive programs for air handling systems and equipment.

Energy efficiency insights

  • Commercial buildings account for 35% of all electricity use in the U.S and 16% of carbon dioxide (CO2) emissions. And according to the U.S. Environmental Protection Agency, 30% of the energy used in commercial buildings is wasted.

  • Furthermore, in commercial office buildings the heating and cooling systems, a majority of which consists of air-handling equipment, more energy for air conditioning is consumed than any other building type.

Decarbonization efforts are a critical part in meeting the goals pledged by President Biden during the 2021 Leaders Summit on Climate — reducing the nation’s greenhouse gas emissions 50% by 2030 and net-zero by 2050 (2005 emissions as basis).

The U.S. Department of Energy decarbonization roadmap is a set of strategies including energy efficiency, clean energy supply, clean fuel sources and direct air capture of carbon. Of these strategies, energy efficiency is the “beginning of the pipe,” improving efficiency which reduces the need for clean energy and fuel and results in lower carbon emissions. Energy efficiency is vital in the world’s journey to net zero and keeping global warming at 1.5 degrees Celsius. The International Energy Agency (IEA), nicknamed it “the first fuel.”

To develop actional processes and to reinforce the importance of energy efficiency, the New Building Institute (NBI) published the “Existing Building Decarbonization Code.” According to the NBI, the code is “… a new way for jurisdictions to reduce carbon emissions and meet Climate Action Plan and public health and equity goals. The need to address existing building stock is great, with 5.9 million existing commercial buildings in the U.S. comprising 97 billion square feet”.
