DC Power for Commercial Buildings

DC Building Power Supply Equipment, Building Controls and Functionality, Lighting, Plug Loads, and Building Microgrid Infrastructure: Global Market
Analysis and Forecasts

Public electric utilities deliver alternating current (AC) power exclusively. However, electronics, LED lighting, and certain other common devices operate on direct current (DC) power. These devices must convert power from AC to DC and step down voltage to the needed level. Unfortunately, the conversion from AC to DC is often inefficient and results in a loss of power. When using renewable wind or PV energy, additional AC/DC transformations are needed, causing more loss. Added together over many AC/DC conversions and voltage changes, total power losses can surpass 20% in some systems.

A growing number of DC power technologies minimize AC/DC conversions and reduce the associated losses. Building managers who installed IP phone systems are expanding their use of power over Ethernet (PoE) to include devices for security, point of access, and wireless networking. Major PoE providers are moving to implement PoE for lighting, monitors, and televisions, and other electronic devices. Bolstered by the standardization efforts of industry groups and growing success at data centers, non-PoE DC technologies are entering into a period of more rapid commercialization and development. Navigant Research forecasts that the global market value for DC power building technologies will grow from $609.1 million in 2013 to $9.7 billion in 2020.

This Navigant Research report analyzes the global market opportunity for DC power technologies in commercial buildings. Five technology categories are covered: DC building power supply equipment, DC building controls and functionality, DC lighting, DC plug loads, and DC building microgrid infrastructure.
