Builders concerned about out-gassing of formaldehyde from medium-density fiberboard (MDF) have long used Medex in cabinets. This exterior-grade product, originally developed for highway signs, is considerably more expensive than conventional MDF or particleboard, however. Now Medite II fills the need for a... Read more

Buildings have a tremendous impact on the environment. In North America, buildings and the building industry account for about 30% of carbon dioxide emissions, 35-40% of ozone depletion, 20-30% of municipal solid waste, vast quantities of natural resource consumption, and dramatic loss of open space each...

Ozone depletion and global warming are two of our most serious environmental problems—and foam insulation materials containing CFCs (chlorofluorocarbons) contribute significantly to both of these problems. The environmentally concerned builder or designer should make it a highest priority to avoid them. Even many of the non-CFC alternatives... Read more

Q.Where would you say architects as a group stand on environmental issues?

We think fresh water supplies are endless, but this idealistic vision is clouded by the smoke of countless forest fires in the U.S. West and elsewhere. Instead of endless bounty, climate change is bringing us catastrophic droughts and flooding that now dominate the headlines and threaten entire regions.

Hi all,

Here's a good follow up to Maria's steel question on Monday.  We have a Midwest project that unfortunately (from a carbon perspective) is required to use a traditional, thick precast facade.  We’re working with the contractor and potential future (not yet bid out) fabricators to determine an appropriate % of pozzolanic material...

It seemed an odd choice but wanted to hear from others on their experiences. The... Read more

We have been trying to compare different options but have only been able to source one expired EPD for an actual window (frame + glazing). Is the typical approach to separately compare glass and framing options? Are we missing something or is there... Read more
