Building ‘green’ reaches a new level

By John Ritter, USA TODAY

PORTLAND, Ore. — Michelle Walsh looks out a wall of windows in her airy new condo high above the Willamette River. Across hills and forests loom snow-capped Mount Hood and, when it’s clear, Mount St. Helens. Below? Construction chaos all around.

Walsh revels in it. She and her husband, Edward, proudly wear “urban pioneer” buttons the builder handed out to early move-ins at the nation’s first large-scale redevelopment to go 100% “green.”

Green Building Timeline

• Pre-20th Century – structures were designed and built by builder-architects who had an ability to understand the entire building from design through construction and lifetime operations. They incorporated enduring passive design and simple mechanical systems to heat, cool and light buildings. Architects in the 21st Century will look back upon these ideas to relearn the basics of climatic design.

• 1930s – new building technologies began to transform urban landscape. Advent of air conditioning, low-wattage fluorescent lighting, structural steel, and reflective glass made possible enclosed glass and steel structures that could be heated and cooled with massive HVAC systems, thanks to availability of cheap fossil fuels. These technologies began a sadly regressive movement in architecture in which architects began to ignore climate issues and their effect on buildings and occupants. Increasing complexity in the industry also brought about specialization in professionals, leading to the loss of the generalists, the builder-architects.  This specialization led to an increasing lack of communication between the professionals and therefore of lack of whole systems thinking in designing the various parts of the building. This problem will only begin to be addressed by the start of the 21st Century through the integrated design process.
