Finding the Green Lining: Surviving and Thriving in an Economic Downturn

A sharp slowdown in nearly all sectors of design and construction has been a defining component of the current recession. Green building has remained a relative bright spot, however, giving firms with strong green capabilities a leg up. This article examines the current climate and offers specific pointers on thriving with a green agenda.

Counting Carbon: Understanding Carbon Footprints of Buildings

Everyone seems to be talking about measuring carbon footprints and designing carbon-neutral buildings, but these terms mean different things to different people. Some focus just on operating energy, while others also look at transportation, materials, and other building-related emissions. As with so many things, the results depend on what you count and how you count it.

Making Air Barriers that Work: Why and How to Tighten Up Buildings

Incorporating a continuous air barrier into a building’s design and construction can save energy and improve the indoor environment, among other benefits. The right materials and assemblies can help accomplish that goal, but careful attention during design and close oversight during construction are essential.

Alternative Water Sources: Supply-Side Solutions for Green Buildings

Both the recent drought in the normally-wet Southeast and impending water shortages in the Southwest are a reminder that water efficiency should be a top priority for our buildings. At the same time, finding alternative sources of water is also important for sustainability and passive survivability. Several sources of water can be harvested at the building level as well as through municipal-scale wastewater treatment and desalination.

Navigating Incentives and Regulations for Green Building

When used in combination, incentives and regulations can be a powerful force for encouraging green buildings. Incentives can be complicated to navigate, but are often well worth the effort. Regulations, on the other hand, can be slow to change, but can raise the baseline for building performance.
