Vision

A family of DC power distribution standards to create microgrids meeting evolving commercial building needs.

The Alliance has a vision of DC microgrids throughout commercial buildings. This hybrid alternating current (AC) and DC platform is being designed as an open architecture focused on reducing or eliminating inefficient AC to DC conversions between power sources and digital devices by converting and distributing power in DC form. We believe that ongoing and increasing demand for improved reliability and energy efficiency across all areas of commercial buildings provides the need for this broad platform.

Occupied Space: The first available EMerge Alliance Standard creates a 24-volt DC microgrid for use in commercial interiors, featuring safety and flexibility along with efficiency benefits. See Registered Products.

Data Centers: A 380-volt DC power standard focused on data center and telecommunication applications is under development. View Presentation.

Outdoor: Power needs exist for buildings exteriors: lighting, signage, and the need to recharge electric vehicles can be addressed with DC microgrids.

Building Services: Larger building loads such as HVAC, motor loads and high bay/industrial applications are often DC-based and are ideally suited for DC microgrids

Throughout these scenarios of building load applications, the Alliance's vision is to promote and facilitate the integration of on-site DC generation sources, such as solar photovoltaics, as well as including other renewable and alternative sources to help create net zero energy buildings.
