It brings up the question that we have debated before. Is it better to build a small “dirty” house or a large Green house? Seeing that Anders Swahn who wants to build this home runs a solar energy startup, we would think that he would get the whole idea of sustainability.

He plans to build the structure as carbon neutral with solar panels, geothermal heating and greywater recycling. It would be built to last for 200 years and, of course, would measure up to Marin County’s green building standards.

The problem that many neighbors have remains the size. Since when is a 15,000 square foot house sustainable. Unless 10 people live there. A lot of materials will be used to build it. No matter how much FSC certified lumber he uses it still would need copious amounts. We’re not even talking about the trees that will removed on the wooded bluff location in order to build the house (not to mention the 2000 sq ft guesthouse).

A more sustainable idea would be to buy another large home like the one for sale just down from the proposed site, a 10,944-square-foot estate, with 11 bedrooms and 10 baths that sits on the market for $37 million. He could add his Green bells and whistles to that estate and be more sustainable without sacrificing his need to live in a ginormous casa.

Exhibit Hall Real Estate Connect San Francisco 2010

While wondering the exhibit hall of Real Estate Connect San Francisco 2010 style at the Pre-Conference Day, amongst all of the technology we figured that no one would go out of there way to promote Green but then we spied some of the “go paperless” inspired companies. In the race to go paperless, a few innovative companies have stepped up to create a paperless universe (at least in terms of contracts).

In the real estate world, agents often use ridiculous amounts of paper in which to disclose, offer and negotiate which in old school terms means that many trees get the saw for that counter offer.  We passed the DocuSign booth and discussed with the folks the Green benefits of using their technology, which allows people to sign contracts with an electronic signature. No more printing contracts. Just sign on-line. We can see the sustainable value in an item that eliminates paper use and general waste. But we discussed how much energy it takes to run the servers that run the DocuSign program. It would take a third party study to determine the paper, ink, transport carbon footprint savings versus the energy used to run something like DocuSign.

We brought this conundrum to another paperless company that not surprisingly goes by the name Go Paperless. Similar to DocuSign this technology allows people to sign and mark up documents using a stylus and tablet PC. Again, saving paper versus using more energy.

We all know that the cost of people runs high in terms of its impact with deforestation, transportation, recycling, shredding, printing, etc. so even at the cost of added energy use, companies that reduce (one of the three Rs) paper consumption can only improve things. We just hope that these companies use this Green philosophy inside their corporate offices as well.

Mousetrap at Maker Faire

Unbelievable but true but this past weekend marked the first time that we attended the Maker Faire. True, in terms of numbers, we only stand a few behind those Makers who’ve made it there since its inception. Our Green posse scurried from the ingenious to downright crazy exhibits. For us Maker virgins, Donna our unofficial group leader for the day, mentioned that people might place this fair somewhere between Burning Man and Exploritorium. That description nailed it.

Why do we love this event and can’t believe that we hadn’t attended before? Not only did we encounter mad scientists of a sort but because almost every artist, scientist, inventor at the fair reuses, repurposes, and recycles other object to create art, cleaning robots, giant mousetraps, and transportation (mostly creatively built bikes).

Even the entertainment had a sustainable element with a solar stage but we caught the band Fossil Fuel at the Human Powered Stage where the bands powered their instruments and amps from bicycle powered generators. That way, we earned our music. Maybe people should try this with their TV so they would have some incentive to exercise.

Now, we can’t be sure about how sustainable it is to jolt 1,000,000 volts of electricity from two five foot Tesla Coils into a guy wearing a grounded metallic suit but the sheer spectacle of watching the long electrical arcs made us think how the electro guy might be able to creatively energize a small town.

Seeing all of the innovations like Algaelab which creates a personal algae photo-bioreactor and the not so practical but highly amusing inventions like the giant mousetrap made us believe that humans can still create mind-boggling inventions and art while not using up precious resources.

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.
