What is the EMerge Alliance?

An open, not-for-profit industry association

The EMerge Alliance

A not-for-profit industry association

• Formed in Fall 2008 by leaders in power, lighting, construction, design, technology and building products

• Professionally managed and based in California

• Membership-based with participation at multiple levels

• Mission:

• To create and promote the adoption of new standards for direct current “DC” power distribution within commercial buildings to improve their flexibility and sustainability

• Geographic focus:

• North America first, with future global plans


Who is EMerge?

The EMerge Alliance

Membership includes over 50 organizations to date

• Companies and organizations who join to support the mission of the Alliance

• Membership levels range from Governing, Participating and General* to Supporting, Liaison and Advisory

• * Members have access to EMerge Alliance Standard and can submit products for registration

• Liaison Members provide synergy with complementary standards and missions:

• ZigBee, BACnet, EnOcean, CABA

• Advisory Council

• Selected annually by Board to provide strategic guidance

• Includes leaders in sustainability, design, construction and building owners



What is EMerge about?

• Promoting a new, open standard for room-level Direct Current (DC) power distribution in commercial buildings

• Safe, low voltage DC power at room level complements AC infrastructure of buildings

• Creating “hybrid power layer” at the load level

• Enabling plug-and-play device flexibility

• Increased energy savings from more efficient use of lighting, controls and other electrical devices

• Facilitating optional use of direct integration with renewable energy sources

A DC power platform for commercial interiors.

» Buildings distribute only AC power today» DC devices must convert AC power to DC

− Converter & power conditioning required− Side effects:

− Higher component count/bulk− Higher cost− Lower reliability

…typically consuming 10 – 20% of power in the conversion process

Interior Loads

Electronic Ballast: Direct DC input would eliminate AC-DC conversion

Think of the “brick” charging your

laptop or cell phone

Digital = “DC”


Example: LED lighting uses DC power» higher efficacy

» power supply efficiency depends upon maximum loading

» AC-DC conversion results in 10-15% losses on loaded power supplies

» direct DC integration can eliminate 120Vac to 24Vdc power conversion

» no need for power supplies and enclosures if remote mounting

» higher reliability

» lighter weight» direct dc use could lead to smaller/lower profile fixtures

Interior Loads


power generation trends

Points of Significant Power Loss

Source:

» Building power distribution is only AC today» Renewable DC power sources must be converted to AC

− Must be isolated from utility grid− Inverter, isolation transformer and power conditioning required

…consuming 7-15% of power generated in the conversion process

New, Open Technical Standard


How It Works


Benefit: Accelerating use of LEDs

• Eliminate 120V AC to 24V DC power conversion

• No need for power supplies & enclosures

• Higher reliability

• Achieve better design

• Lighter weight, lower profile fixtures

• Fewer finished components

• Higher efficacy (light output per watt)

• Internal AC-DC conversion results in losses

• LEDs driven by DC up to 10-15% more efficient

LEDs are inherent users of DC power



Benefit: Faster returns on renewables

The EMerge Alliance

Accelerate owners’ return on investment for on-site renewable energy.

Use less energy going DC direct, ie with photovoltaics• Improve power utilization• Eliminate DC to AC conversion• Maximize efficiency• Back up with battery or tie back to AC grid
