The Path to Drawdown: Building Automation Systems

Buildings and construction account for 38% of global CO2 emissions and 35% of total energy use. And much of the energy-use in buildings is the result of heating and air-conditioning, lighting, information and communications systems, security and access systems, fire alarms, elevators, appliances, and indirectly through plumbing.

Most large commercial buildings in industrialized countries have some sort of centralized, computer-based building management system that monitors, evaluates, and controls these systems. That centralized management is called building automation system. Building automation systems use sensors to constantly scan and rebalance energy use to maximize efficiency and effectiveness. New buildings can be equipped with a building automation system from the start, and old ones can be retrofitted to incorporate it and reap its benefits.

Adopting automated, rather than manual, building management systems can result in over 20% more efficient heating and cooling, and 8% more efficient energy use for light, appliances, etc.

Current adoption of building automation systems varies widely by country. Project Drawdown estimates that, for building automation systems to make a significant dent in global emissions, their adoption needs to grow particularly rapidly in developing countries:

  • <::marker> In 2018, over 75% of buildings in some high-income countries were managed by automated systems while some developing regions had not adopted them at all. 
  • <::marker> By 2050, if building automation systems are adopted by 100% of commercial buildings in OECD countries, 80% in China, and 50% in all other regions, they can help avoid up to 10.48 gigatons of CO2 emissions.

What We Want to See Improve

Divest from Oil & Gas Business

Up to 18% of their revenue (p. 120) comes from selling equipment to the oil and gas sectors. These sales help perpetuate these high-emitting industries. We urge JCI executives to divest from this business as soon as they can and focus entirely on the Drawdown solution of building efficiency.

Reduce Absolute GHG Emissions

We applaud Johnson Controls for reducing their GHG intensity (p. 4) by a substantial amount over the last decade. But rather than reducing their emissions intensity, which they achieved by offsetting (p. 16) their emissions through the purchase of renewable energy certificates, we want to see Johnson Controls work to reduce their absolute emissions. Cutting absolute emissions is the only way to genuinely help the world achieve a zero emission future.

Switch to Renewable Energy

Johnson Controls is heavily reliant (p. 78) on fossil fuel energy (gasoline, diesel, propane, butane, jet fuel, heavy fuel oil, and coal) and biomass and ethanol, which are low-emission but still not clean. And their use of these fuels have slowly increased between 2017 and 2019 ( 1.34% CAGR). We urge them to transition to renewable power for their operations, and to electric or green hydrogen for their fleet and transportation as soon as possible.
