Standard 202 is ASHRAE’s first standard focused on the commissioning process. The commissioning process as detailed in Standard 202 applies to all construction projects and systems and […]
The U.S. Department of Energy (DOE) recently issued new energy efficiency standards for ballasts sold as part of new metal halide luminaires. (To be clear, replacement ballasts are not covered.) The new rules strengthen current standards while expanding their scope, and will affect availability of 50-1000W luminaires. The deadline for compliance is February 10, 2017. […]
ELECTRICAL CONTRACTOR recently published an article, written by Craig DiLouie, LC, defining a new dimension of lighting control–white light color tuning. Check it out here.
WattStopper and Durell Control Systems have published a new white paper examining best practices for control systems integration in high performance buildings. The paper uses case studies to explore how project partners can successfully collaborate with design and construction teams, focusing on two recently completed high performance buildings in London, Ontario, Canada. Building owners can […]
Growth in construction spending in 2013 continued to outpace the U.S. economy. Estimated total put-in-place construction spending—actual numbers, not seasonally adjusted—grew at a healthy 4.8% in 2013, increasing to about $900 billion. This rate was slower than the previous year’s increase of 9.2%, however. The residential market saw the biggest gains, as a robust market […]
Republication of Postings from the U.S. Department of Energy (DOE) Solid-State Lighting Program by Jim Brodrick, U.S. Department of Energy Solid-state lighting has proven that it can deliver high-quality light with substantial energy savings in many applications. But dimming can still be an issue, as CALiPER testing and GATEWAY demonstrations have shown. This concern was […]
The U.S. Green Building Council recently released the fourth generation of the Leadership in Energy & Environmental Design (LEED) green building rating system. Projects can register for LEED 2009 or LEED v4 until June 1, 2015, after which LEED v4 will be required. The new LEED covers new construction, commercial interiors and existing buildings, with […]

Guest post by Charles Knuffke, WattStopper Lighting professionals in California are watching the approaching New Year with some apprehension, for 2014 brings with it a completely revamped and far more aggressive energy code. While California’s Title 24 Energy Code has had a reputation for being a leadership code in the past, the 2013 revision more […]
The latest generation of energy codes and standards require that building exterior lighting be turned OFF and/or reduced when not in use, producing significant energy cost savings. This includes outdoor area/parking lot, bollard, entrance/exit canopy and wallpack lighting. The following decisions will ensure that energy consumption is minimized by turning lighting OFF or turning it […]
