The economy definitely had an impact on this year’s West Coast Green with less venders but with less money that mean that people just had to get more creative with less moola such as the floating island, show gardens and even the sustainability built Jewish Sukkoth. The usual green rock stars like Eric Corey Freed and Michelle Kaufman made their presences felt with their energetic personalities.

Kaufman, in fact, talked about the use of Green pre-fab homes and the affordability factor. She mentioned that she gets most energized by the fact that her parents and grandparents who live in Iowa would have to go through a long drown out and costly experience if they wanted to build a Green home, only because the resources don’t exist there – yet. She wants to make Green pre-fab homes affordable to all people. Fab Michelle, fab. She went off on the top three production homebuilders who she says do “crap” as their homes are not well made, not well designed, not healthy and efficient. “The big home builders won’t be proactive to make changes said Kauffman. American homebuilders being reactive? We can’t believe it.

We also could believe how interesting the planetarium project at the closing party at the Academy of Sciences was. The special WCG program featured An Ecological View of the Cosmos. This interactive program (accompanied by live narration presented by media artist David McConville, the Director of Noospheric Research of The Elumenati and a Director of the Buckminster Fuller Institute and classical/new agey music from Christen Lien and Rachel Bagby gave us a stirring, complex and though provoking view of the universe. In fact, we learned from this program how when someone asks us if we think that we are the center of the universe we just might be able to answer affirmatively.

On the creatively intriguing side, we walked into the Icynene Inc. display booth only knowing that they create their Icynene LD-R-50 spray foam insulation partially from Castor oil. Honestly, we didn’t exactly know the origin of Castor oil. Castor oil comes from Castor beans (not true beans from Castor plant) and don’t serve a normal food source, so not food for insulation here. Castor crops don’t require pesticides or fungicides or even water to grow and are rapidly renewable. For this insulation, they use 15 eight percent castor oil (and unfortunately 85 92 percent polyglycol, which in our eyes is like using B15 B8 biodiesel. Fifteen Eight percent is better than zero percent but still a long way to go. This product helps eliminate dust, pollen and contains no VOCs as it is water blown. Most traditional cellulose insulation comes from 80% newspaper (up to100% post-consumer recycled) and 20% binders and fire-retardants, commonly borax, boric acid, sulfuric acid, ammonium sulfates and/or other chemical compounds. Smell the goodness.

One of the most disappointing aspects of PCBC would be the continual greenwashing that some organizations and companies wish to convey to the public and trade. The SFI (Sustainable Forestry Initiative) had booth and lots of literature about how they which on the surface seems on the track to be doing the right thing with their Green certification but if you check below the tree cover it might not seem so verdant.

Most Green people would be disillusioned with the fact that SFI finds its roots firmly planted with the lumber companies which of course offers no value. Then they somewhat cleaned up their legitimacy a few years ago by creating third party certification, publicly available standards and a more transparent process.

We met the Director of Green Building for SFI at the PCBC booth where he did the hard sell offering such info that they continue to push the USGBC to include SFI certified wood in the LEED standard. To us, it seems like a lot of lobbying and less to do with the legitimacy of the certification.

When it comes down to it, the SFI wants people to think that they reign superior or even equal to FSC certification but take a look at some of the comparisons where SFI allows:

-use of genetically modified trees

- logging close to rivers and streams that harms water supplies

-use of toxic chemicals while FSC does not allow these in the forests.

And we can go on and on but as they say a picture is worth a thousand words so check out the SFI versus FSC forest land photo courtesy of heartofgreen.

‘nuff said.

Even in a Greencentric city like Berkeley, locals and Bay Area visitors would be Green with envy when they see the just opened David Brower Center. It feels healthy just to walk through the Green down-to-the-bones building which combines advanced technology along with simple recycled materials.

When entering for their housewarming party we had a difficult time not noticing the soaring concrete walls which made us think more dot com than gallery. The fact that in creating a building with an oh- so-feathery carbon footprint (when compared to most structures) Principal Architect, Daniel Solomon included up to 70 percent slag in those walls.

Just like people, what Green buildings have on the inside can be the key. Anyone (or any building) can have a great exterior but look at the Brower Center’s guts and soul. We love the radiant heating and cooling that runs through the floors, as well as the water catchment system and giant cistern that significantly reduce the building’s water use. The building even employs small aspects like the zinc siding and photovoltaic panels that double as sun-shades. The zinc siding will last numerous years without being treated.

The designers and builders designed the edifice be 40 percent more energy-efficient than conventional ones, which includes a day lighting program that uses high-efficiency lighting with automatic controls limit use when daylight is adequate. Normally we don’t get to excited heading to the restroom (no jokes please) but we definitely got giddy with the Icestone countertops, waterless urinals and high powered hand dryer. We’re talking ten seconds max to dry hands.

Besides the physical structure the Brower Center works on the social justice level as it houses various NGOs and ecologically minded companies such as: Center for Ecoliteracy, Community Alliance with Family Farmers (CAFF) and the Earth Island Institute. We can’t speak for all the staff and workers but having the Brower Center as your office would actually inspire someone to want to come to work.

The Orchard represents San Francisco’s only hotel to earn this honor, the Orchard Hotel is the second hotel in California and fourth hotel in the world with this certification. The inspiration from these green hotels comes from its 85-year-old owner, Mrs. S.C. Huang, who has pushed her environmental agenda and created more environmentally safe and sustainable hotels after the untimely cancer-related deaths of three family members.

We know that points don’t represent everything but for those strictly into the numbers the hotel achieved 35 out of a possible 36 points on the LEED-EB scorecard.

Those not familiar with LEED-EB shouldn’t expect alt energy (but it would be nice), large scale green building materials (foundations, roofs, etc) and other large ticket green building attributes. Here the sustainable aspects come more in the form of interior and service. We like the fact that the hotel is Energy Star rated and 90% more energy efficient than comparable hotels. It also contains a plate and frame heat exchanger installed on the rooftop which decreases power needed for climate control and cooling.

At night, guests can sleep (or whatever they else they do in bed) better knowing that the mattress covers are made from organic and naturally anti-microbial fibers, and the wood in guest room bed bases comes from Forest Stewardship Council (FSC) certified sustainably harvested forests.

The hotel even took over the formerly Vignette restaurant (now christened Daffodil) and changed the menu to consist of mostly local ingredients and organic produce and meats from small California farms however we have yet to dig our forks into the new fare so we’ll have to see about that Green aspect later. After all, fares fair.

We got one of the choice rooms overlooking the man made lagoon which plays home to koi, frogs, various plant life and Artemis and Apollo (two impressive swans that live in the lagoon and strut their way around most of the hotel). By the way, the koi pond uses recycled water from the site which they clean and filter prior to entering the pond.

The sparten yet comfortable rooms offer lots of Green aspects. Small things like offering fair trade, organic coffee and not having those tiny shampoo bottles littering the bathroom made a big difference. Here they provide shampoo, lotion in bulk dispensers. We also like that all restrooms use recycled tiles and granite. While in the bathroom, we give wet kudos to the water saving low flow showerhead, which offer plenty of water pressure for one person (but not two, if you catch our drift).

We slept easy not only with a comfy, firm mattress but breathing easy with the low VOC paints were used throughout the rooms and rest of the hotel. It also helped us to know that solar panels provide 12% of the hotel’s electricity.

We know that a boutique type hotel needs a relaxing but unsustainable hot tub (yes, we partook and didn’t feel guilty) but we didn’t feel too keen about the microwave that inhabited our room but even with the little monster we felt pretty energized about our stay. It sure beats a stay in an unsustainable Motel 6.

We could very well come all the way to wine country without visiting some organic, sustainable and do we dare say biodynamic wineries. Stay tuned.

In addition to the great views that most people would ooh and ah about, what gets our green genes going are some of the less sexy LEED elements. Instead of subjecting occupants to dingy indoor views and lighting, the architects designed architectural curtain wall to enable direct views of the outdoor environment for 90% of the building’s occupants. We also like the fact that they used recycled materials for at least 10% of the material construction. The vast majority of the recycled content comes from the building structural steel and in the aluminum curtain wall, not recycled materials used inside the building. Way up high in the sky, the roof will be a highly reflective, lightly colored ‘cool roof’ system that will reduce the affect of urban heat islands. Although the “cool roof” is cool, we’d like to see an actual Green Living Roof up top but we can’t have it all.

With several other Green elements on tap we’re actually looking forward to seeing something attractive and Green hit the South Beach/Soma area. Memo to Tishman – Speyer execs: “Keep sending out those Green building memos.”

The Orchard Garden Hotel continues to experience a delayed opening. Yes, the soon to be LEED certified hotel originally scheduled to open in September now has a realistic November on its sights.

The delays didn’t detract from the evening where Mayor Gavin Newsom joked that instead of a ribbon cutting ceremony the evening offered more of a preview. Even, the General Manager Stefan Mühle joked that the crowd should grab paint brushes. Instead they grabbed champagne flutes, wine glasses, and appetizers (especially the sweet gazpacho) and got a mini tour of the five completed rooms.

While most people admired the coziness and sightlines of the rooms and suites, a couple of us focused on the green aspects such as the FSC certified maple wood furniture, low flow water fixtures, Luna Textiles and key card energy system. The rooms offer a clean, spartan yet cozy look. We weren’t exactly thrilled to see Chinese granite bathroom countertops but you can’t have everything green.

We actually feel sorry for the owner for the owner of the Green house in Bernal Heights. That same property (338 Holladay Ave.) has been languishing on the market for almost three months. That’s the same residence where the house’s owner wrote a letter to the editor of the San Francisco Chronicle several weeks back, which practically exclaimed a rebuttal to the paper’s articles saying that Green houses are all the rage and will sell like hotcakes.

The owner can’t be a happy camper as he and his agent continually drop the asking price from $1,279,000 to $1,195,000 to $1,049,000 to $994,000. The owner claims that location sells houses, as evidenced by the Green house in Noe Valley.  True the Noe Valley Green house location represents a superior addy to the one in Bernal Heights. Also, that Noe Green house sale occurred in a slightly warmer market.

There may be a degree of truth in the owner’s statement but instead of location, location, location the seller and his agent should be more concerned with marketing, marketing, marketing. And education.

In this market you can’t expect a green house to sell that when people don’t know what it is, or its environmental, health and economic benefits. The real estate agent selling the Green house appears to have little idea of how to market the place. To him it’s just a cute eco-home for the warm and fuzzy eco-family. That’s sweet. From the marketing flyers and listings you almost couldn’t tell this house from any other one in Bernal Heights.

Is a house a house? Is a car a car? Would you want a Yugo salesman selling you a Ferrari? But they’re both cars aren’t they? Tires, engine, seats. What’s the difference? Same with the house. Roof, stairs, kitchen what’s the difference?

Green houses, like Ferraris can rate high as far as technology so if you want to build, buy sell, or make a dwelling more green then find someone who knows about what’s under the engine. Need a referral than contact us and we’ll find you someone who knows their Green stuff. Now please take that Yugo out of our driveway.

With the Arterra, San Francisco’s first LEED certified San Francisco condos, just about ready to go into pre-sales it’s no surprise that some visitors in the sales office appear from curious to confused.

Some prospective buyers who drifted around the sales office came for the Green factor but others don’t know green from pink. The salesroom doesn’t exactly push the green aspect. Those who don’t have an attention to detail could easily miss the bamboo kitchen floors, and the dual flush toilets. Even so, one green product continually baffles potential buyers – the Trespa rainscreen system. It more than baffles, it disturbs some.

We’re not exactly fans of bedding down in high-end coffins, except maybe during Halloween, so people here should get over their fears of something new. The rainscreen system isn’t exactly the new green kid on the block. Builders have been using this overcladding technology since the 1940’s in Scandinavia.

For too many years America builders and engineers have sought to resist nature rather than embrace it. You can’t beat Mother Nature and why should we? Traditional thinking has been to prevent rainwater from entering buildings by use of barriers and sealants. However we don’t live in a vacuum so do to poor workmanship, material degradation and building movement (here in SF?) that system breaks down.

The beauty of rainscreen overcladding comes from the fact that the technology uses the effects of the wind to control rain water from entering the building.

The design uses simple pressure effects of the wind to dissipate the rain water energy. The specially designed drainage paths direct the water away from the opening.

The project manager at the Arterra describes the Trespa rainscreen system like a kind of Gore-tex as it actually allows moisture to flow in AND out. Most other buildings are hermetically sealed which don’t allow any evaporation which traps moisture in the walls and can lead to mold or other hazardous problems. ]]> http://greenerati.com/2006/09/21/who%e2%80%99ll-stop-the-rain/feed/ 0 http://greenerati.com/2006/09/16/ashes-to-ashes/ http://greenerati.com/2006/09/16/ashes-to-ashes/#comments Sat, 16 Sep 2006 07:09:58 +0000 pepeflaco http://greenerati.com/?p=197

Normally the thought of ash brings to mind volcano eruptions, funerals, and maybe religious holidays but for us and green builders it’s about flyash and foundations. So, when discussing the topic with one of San Francisco’s up and coming LEED-AP architects (Melanie Jacobson) she mentioned that the CHPS school they are building in the Sacramento area will have a fifteen percent flyash concrete foundation we looked quizzically at her. Why only fifteen percent? She mentioned that that percentage was about as high as their structural engineers deemed to be sound.

We’ve heard other local green buildings contain as high as thirty percent flyash. So, why the discrepancy? It depends on the configuration of the building, the weight on the structure and most importantly what the structural engineer says.

What the heck is flyash? Flyash is a by-product of coal-fired electric generating plants.

Don’t think that this stuff is some newfangled substance. They used flyash concrete to build the Hoover Dam in 1929. Yes, we know that’s out of our area. But consider on your next sojourn to Vegas you can make a side trip to check out the Dam and then impress friends and strangers with your knowledge of flyash.

Raise the green flag for this powdery substance because as an industrial by-product, it would just be waste but now many resource companies recycle it into cement. It gets better because flyash cement requires less water than Portland cement so it is easier to use in cold weather. It can be an inexpensive substitute for Portland cement in many cases. Everyone has their favorite powder but this one happens to be one of ours. ]]> http://greenerati.com/2006/09/16/ashes-to-ashes/feed/ 0
