The commercial sector is primed with opportunities to increase energy efficiency, as commercial buildings are high consumers of energy.Lighting is often considered the low hanging fruit in terms of efficiency upgrades in commercial buildings since the related systems are cheaper than other building upgrades focused on efficiency, such as an updated HVAC system or building energy management system.LEDs have experienced growth in the commercial lighting market as the cheaper and more inefficient legacy lighting technologies, such as fluorescent, high intensity discharge (HID), or halogen, are being phased out.Historically, fluorescent tubes have led in the commercial building market, but they are losing favor to the more efficient and longer lasting LEDs, especially in new construction and retrofit projects.CFLs have experienced considerable market growth in the recent past, as they are more efficient than many other lighting types.Yet, they are losing popularity due to health concerns about mercury and the declining price of LEDs.According to Navigant Research, global lamp revenue is expected to decline from $23.0 billion in 2017 to $21.5 billion in 2026.This Navigant Research report analyzes the global market for energy efficient lighting within commercial buildings.The report briefly covers the market issues, including key drivers and barriers, related to the energy efficient lighting market for commercial buildings. Global market forecasts for lamp and luminaire unit shipments and revenue, segmented by building type, lamp type, construction type, and region, extend through 2026. The study covers seven lamp types and eight building types, as well as luminaire and lamp unit shipments for new construction and retrofits.
