Fluorescent and LED lighting get most of the attention, but there are other efficacious lighting technologies that could illuminate our future.
When it comes to lighting, fluorescent and LED technologies currently are most often specified in green buildings, but their siblings, induction and OLED (organic light-emitting diode) lighting, have been trying to earn a place at the table.
Nikola Tesla first demonstrated induction lighting in the late... Read more

Finding cost premiums as little as 5% over LEED Platinum, a new report highlights how D.C. can incentivize net-zero and Living buildings.
A recent analysis suggests making the jump from LEED Platinum to net-zero energy costs less than one might think, requiring just a 5%–10% first cost premium for a new commercial building. The study also evaluated premiums associated with net-zero water and Living Building Challenge certification and recommended policy changes... Read more

Building codes restrict the use of many heat-recovery technologies from commercial kitchens due to fire risk, but recent code updates should make it easier to specify Halton’s Heat Recovery Unit.
Even though ASHRAE 90.1 requires heat recovery for exhaust exceeding 5,000 cubic feet per minute (cfm), commercial kitchen ventilation is exempt from these requirements due to fire risk from accumulated grease. International Mechanical Code (IMC) 514 also prohibited heat and energy recovery in commercial kitchens, but the... Read more

An entry-level alternative pushing LEED to get better would be great, but GBI’s Green Globes needs to start by joining the green building community.
TurboTax gets audited. Now, so does Green Globes.
The green building rating system run by the Green Building Initiative (GBI), would-be rival to the U.S. Green Building Council (USGBC) and its LEED rating system, has been likened to the popular income tax software because it takes a complex problem and... Read more

Concrete is responsible for a huge proportion of global carbon dioxide emissions. A few companies want to reverse this cycle by sequestering carbon in building materials.
Driving down California’s Coastal Route 1 from Santa Cruz to Monterey, you might notice a couple of massive 500-foot smokestacks venting flue gases from one of California’s largest power plants, Dynergy’s Moss Landing Power Plant. This 2,500-megawatt (MW) facility emits 2.3 million tons (2.1 metric tons) of carbon... Read more

With attention to installation quality, Knauf’s EcoSeal and Owens Corning’s EnergyComplete demonstrate that they can create air barriers and reduce use of SPF.
Two products—EcoSeal from Knauf and EnergyComplete from Owens Corning—have been on the market for several years as spray-applied latex sealants for making building envelopes airtight during new construction (see Spray-Applied Latex: A New Tool for Air-Sealing). Until recently, however, we haven’t had... Read more

Early versions of LEED pull ahead in air quality but lose ground with inadequate lighting, resulting in a tie with non-LEED buildings for overall workplace happiness.
With data from 65 LEED-certified buildings—but only those certified under LEED v2.2 or earlier—a recent study concludes that workers in LEED buildings are no more satisfied with indoor environmental quality than those in non-LEED buildings. While Stefano Schiavon, one of the authors of “Occupant satisfaction in LEED and non-... Read more
