Quality of Energy
Our built environment relies on the quality of energy available to power it. Nationwide investments in grid modernization and resiliency are driving electrification, converting buildings to more carbon-friendly electric systems, and facilitating installation of renewable energy sources at the building level. With this, Direct Current (DC) power is key to easily connecting our buildings to renewable resources and energy storage batteries.

Our built environment is almost exclusively powered by Alternating Current (AC). However, from renewables and electric vehicles to mobile devices and IT networks, the use of DC power is already widespread and growing. Converting AC to DC power results in efficiency losses of up to 10%¹, and every power conversion represents not only additional material costs, but a potential failure point for the connected devices and systems. In addition, direct DC power connection to renewable energy sources combined with DC-powered building systems, has been shown in a simulation to generate an estimated 10 to 18% in energy savings² when compared to AC-powered commercial buildings. To help foster the adoption of the use of DC power in building design, the US Green Building Council introduced a LEED® credit for Direct Current Power Systems³ as well as consideration for DC-powered systems under its LEED Zero certification.

LED lighting already requires DC power to operate. Acuity Brands’ DC2DC architecture provides for distributed DC power to a LED lighting system, enhancing its efficiency by eliminating the need and cost to convert AC to DC power at the luminaire, and facilitating the installation and commissioning of lighting controls. Intrinsically more efficient by design, our DC-powered lighting architecture also delivers savings at design and installation, facilitates maintenance, and empowers lighting design focused on sustainable and well-being applications.
