Geothermal is evolving from individual buildings to campuswide systems...

The International Code Council (ICC) is breaking new ground with the International Green Construction Code (IgCC). Due this spring, it will be the first internationally acknowledged code focused on high-performance buildings. It contains a comprehensive and detailed treatment of high-performance-building strategies, including energy conservation and commissioning (Cx)....

A properly designed UFAD system takes advantage of thermal stratification. The key is to have a diffuser that rapidly mixes air before it penetrates the stratification layer at the upper end of the occupied zone. The pressurized plenum (the area between the slab and the raised floor) essentially is a large duct maintained at a constant pressure differential—typically, 0.05 to 0.10 in. w.g.—to the room above. This pressure is maintained through the supply of conditioned air from a number of supply-duct terminations...

Four strategies to drastically reduce energy use in commercial buildings...

The services provided by mechanical engineers are crucial to the success of sustainable or "green" projects. It is vital to select a qualified professional or firm that will complement your project team....

The GGBP is part of PlaNYC, an effort undertaken by New York City’s Office of Long-Term Planning and Sustainability to prepare the city for 1 million more residents, strengthen the local economy, combat climate change, and enhance quality of life. So far, PlaNYC has built and preserved parks and housing, enhanced mass transit, and made existing buildings more energy-efficient....

The article “skeptic finds that global warming is real” misleads. As noted by Professors Patrick Michaels and Robert Balling in their book “Climate of Extremes” (2009), there is no serious disagreement with the degree of climate warming since 1900, or the change since 1950 confirmed by Professor Muller. The questions of climate change, however, are fourfold, of which only one is recent global temperature rise. ...
