Green Building Elements

Green building tours are becoming popular in many cities, and are an excellent means of introducing green construction options to professionals and laypeople alike.

The Cascadia Region Green Building Council will host a tour of green buildings on September 25th, 26th, and 28th in the Victoria, Vancouver, and Okanagan regions of British Columbia. British Columbia is the Canadian province with the most LEED-certified buildings per capita, and Cascadia’s Green Skyline tour will include over 25 green buildings. Both residential and commercial tours will be included. They will emphasize what constitutes green design and offer ways to incorporate it into a project, as well as detailing the costs and benefits of building green.

The tours are designed to be walkable, bikeable, and accessible by public transit. Several organized bike tours will also be offered. See the CRGBC website to register.

As part of the current Canadian election campaign, leaders of the Canadian Liberal Party have announced a plan for spending more than a half a billion dollars to improve the energy efficiency of homes across Canada, if they are elected next month.

Under the four-year proposal, the Liberals would offer homeowners $10,000 in financial support for investing in energy-saving measures such as insulation, weatherproofing and more efficient heating systems.

Up to $10,000 would also be available to homeowners as an interest-free “green mortgage loan” to help with up-front costs and major retrofits.

Sprawl is a constant issue at the outside periphery of every city in the country. Although matters have abated temporarily in the midst of the housing and mortgage crunch, new construction continues to decimate the countryside at further distances away from the city centers. However, the state of California is weighing a measure in the state legislature that might help curtail the growth of exurban sprawl developments.

The extension of suburbs further and further out from the core of businesses and services not only consumes acres of land, with its attendant loss of woods, fields, wetlands, farmland, and animal habitat, but it also requires miles of pavement, and the attendant infrastructure (sewers, phone and power lines, etc.) to support the new development. Residents of these displaced communities are forced to rely on cars for more and more of their access to various services and amenities, and very often travel greater distances to work as well as other destinations. This increases both the consumption of fuel resources and the pollution caused from the extra travel. Read the rest of this entry »

The air is going to get a little bit cleaner come January, 2009 - and that has nothing to do with a new presidential administration.  The California Air Resources Board’s dramatic Air Toxic Control Measure known as “the CARB rule” will go into effect January 1 and will, among other things, mandate a reduction in formaldehyde levels in composite wood products like particle board, hardwood plywood, and medium density fiberboard.  Manufacturers of composite wood products have less than four months to adapt to the new requirements or they will be unable to manufacture or sell their products in California.

Formaldehyde came into the public consciousness this past Winter as trailers used for Hurricane Katrina victims were found to contain dangerous levels - click here for those findings.  Urea-formaldehyde is a volatile organic compound that has been linked to health issues ranging from persistent eye and skin irritation to asthma to, in extremely high levels, cancer.  It has been practically banned in Europe, Japan, and Canada.  The United States Green Building Council awards LEED credits for buildings that have eliminated added urea-formaldehyde.  The inclusion of the word “added” is due to the fact that small levels of formaldehyde occur naturally in wood.  Urea-formaldehyde is used in composite wood as a drying agent for glues and adhesives, significantly speeding up the manufacturing process of the composite wood.  For this reason, non-formaldehyde composite woods will come at a higher price.  Add in the increased demand due to the CARB rule and the current limited supply of formaldehyde-free composite wood and we could see increased prices across the board for composite wood products like furniture, cabinets, moldings and millwork, doors, and many other products.  Read the rest of this entry »

The Heathman Hotel in Portland, Oregon, a member of the Carino Collection and Historic Hotels of America, recently remodeled all 155 of the hotel’s bathrooms, maintaining the standard of luxury that the hotel is famous for, while lowering its environmental footprint.  Ankrom Moisan Associated Architects designed the remodel with the goals of being locally responsible, sustainable, and efficient. 

Some of the features of the remodel include:

• Preserving existing teak trim, mirrors, stone vanities and tubs.
• Using Forest Stewardship Council certified wood that adheres to all the practices of the Smartwood Rainforest Alliance.
• 40% recycled content tile on the walls and floors.
• Use of LED lighting custom designed by Eleek Lighting and Design.
• Shower heads that reduce water usage by 10 to 20 percent.
• Toilets that will reduce water usage by 50 percent.
• Approximately 95%, by volume, of the debris from the bathroom demolition was donated to Portland’s ReBuilding Center, the largest non-profit building materials resource in North America.

The Heathman is not new to sustainability and conservation.  It was one of Portland’s first hotels to receive incentives from the Energy Trust of Oregon for energy efficiency upgrades.  It also participates in Pacific Power’s Blue Sky program, purchasing 30 percent of its electricity from Blue Sky renewable sources.  Chris Erickson, the Heathman’s general manager, said, “We are thrilled to team with AMAA (Ankrom Moisan Associated Architects), a company that shares our sustainable values and commitment to community.  They’ve helped to take our existing sustainability efforts to the next level.”

The Heathman’s guests are invited to see, and experience, how luxury and sustainability can coexist.

When San Franciscans and anyone else living in the Bay Area hear about Richmond the first thing that comes to mind certainly isn’t anything related to Green, Eco, or Sustainable anything. That will hopefully change as the semi-rural farm Eco Village Farm Center, which already teaches sustainable farming and growing practices to underprivileged local youth, recently added a solar system to power the farm.

In a not so pastoral location surrounded by freeways and railroad tracks, the Eco Village offers a green sanctuary to local youth who wish to find a green place to learn and relax. The farm grows a variety of vegetation including: fruit trees, Oaks, Beach, Banana, California Buckeyes, Bay Laurels, Blackberries and Walnuts.

The recently added solar system not only will decrease their energy bill but many young Richmond residents received an opportunity to help install the system. The program sponsored by Solar Living Institute, Solar Richmond, Rising Sun Energy Center, Sun Light & Power, SunPower Corporation and Bay Area Air Quality Management District brought a human element to the system by providing access for disadvantaged children to gain skills and interest in the green business movement.

We’re big fans of this project not just because of the reduced carbon footprint but the program gives youth an opportunity to become more eco-literate, as it creates a cross cultural dialogue and moves across economic lines as well. Learning about Green power, grey water harvesting and urban food production isn’t just for people who can afford it.

We’d like to see more solar training and eco-literacy spread from the suddenly Green city of Richmond.

With new owners set to move into the the LEED light Arterra we throughout that we’d pay a visit to San Fran’s newest LEED certified condo. Arriving on bikes, we discovered that no bike racks exist for those wishing to inspect the demo models. Thus we had to pull out bikes into into the sales office. Walking though the corridors to the demo unit, we couldn’t help but smell the VOCs rising though the air. Kind of disappointing for a LEED-NC building.

Once we arrived at the demo unit, we felt sad to see granite countertops in both the 1 and 2 bedroom units. We asked the salesperson about the “Green” aspects of the condo and he didn’t know much about the Green aspects but he thought that most of the Green attributes (aka LEED points) weren’t located in the condos but we more part of the overall building. Give that man an organic cigar as most of the LEED points came about in the low hanging fruit (landscape, location and other interior elements) as the green aspects hardly appear in the living spaces. We noticed the dual flush toilets and triple pained windows but aside from that we didn’t note many green offerings.

With buyers scheduled to move in today or tomorrow, hopefully they don’t believe that they are moving into the greenest of the green condos. We’ve heard that the Arterra folks don’t really care about the whole LEED system other than using it as a marketing ploy. Too bad, as the sales figures for the Arterra sit at around 54% sold. Maybe people see it the Arterra for what it is, a very light Green housing option with a favorable price tag.

What does it look like to build a house with lots of green features? We see pictures of the finished buildings, and we read about the features that make them green. We know about the importance of good insulation and reducing electrical loads and choosing efficient equipment. But what does it look like while it all goes together? Read the rest of this entry »

“Workforce housing” is a term being heard more and more, used place of the more familiar “affordable housing”. It differentiates between housing that is intended to accommodate people from the lowest income brackets, and housing for the lower middle class, people who have steady employment but have been priced out of the housing market in many areas.

According to Wikipedia, workforce housing has four defining elements:

• Affordability
• Home Ownership
• Key Workforce (in other words, composed of critical members of a community’s workforce such as police officers and teachers), and
• Proximity (to employment centers)

A community in Canada has an unusual form of solar power that can provide over 90% of the annual heating and hot water needs for the homes, despite being situated in a cold Alberta location where winter temperatures can reach -33 degrees C (-27 F).

The Drake Landing Solar Community collects solar energy in a heat storage fluid through an array of solar panels on the roof of each home and covering all of the garages at the back of each home. The heated fluid is transferred to a neighborhood energy center, and then into the ground beneath an insulated layer, where the heat is stored in the earth.

Combined together, the 52 home community is able to collect and store enough energy from the sun during the summer that the ground storage temperatures reach 80 degrees C (176 F). This heat is sufficiently insulated beneath the ground that it can be drawn from throughout the winter to provide heat and hot water.
