Hard economic times and changing social trends have some museums undergoing a 21st century re-design. The focus is on creating more visitor-centered exhibits using new media tools and more input from the public. Some technology and history museums in the Bay Area are helping to lead the way, as you will hear in our radio piece.

When the public is invited in to help design exhibits, it can create faster turnover and more affordable exhibits. The Tech Museum in San Jose, for example, held a competition in Second Life. The public was asked to design exhibits on the theme of art, music and film. Entries came from as far away as England and China. Winners were awarded five thousand dollars each and asked to translate their designs into a real life gallery space. That exhibit is now on display at the Tech.  According to the Tech's Director, Peter Friess, the exhibit could have taken three years to design. Instead, it took six months. Museum directors are hoping that asking the public to help generate, share and update content will also create more loyalty and drive up ticket sales.

Some people cringe at the idea of asking the public to design museum exhibits. They point to the unlimited number of cat videos on You Tube and ask, "is this really what we want to do to museums?" The museum directors I spoke with say that there is still a role for the curator in this new model, but as more of an educated facilitator than an autocratic, removed taste-setter. Nina Simon, a participatory exhibit designer who writes a blog called Museum 2.0 thinks about this question a lot and has some interesting ideas.

While the participatory, hands-on movement has been around for awhile, these museums are picking up on a cultural shift – and it's not just Bay Area history and technology museums. The Smithsonian American Art Museum was the first to offer an alternate-reality game. The director of the Walters Art Museum in Baltimore thinks the mission of museums may be expanding to include social services. The Brooklyn Museum created a temporary exhibit, "Click," using crowd sourcing and the Museum of Minnesota created a permanent exhibition based on nominations from the public. I wonder what Web 3.0 will bring?

Sea level rise scenarios for San Francisco International Airport.
Click the map to see a larger image.

The most recent estimate looks pretty dire. The Bay Conservation and Development Commission (BCDC), a state planning agency, says it expects San Francisco Bay to rise about 16 inches by 2050, and 55 inches by the end of the century.

The map on this page shows what San Francisco International Airport and the surrounding area would look like, if the bay rose a meter (roughly 36 inches). You can check other maps around the bay as well.

And the real danger of that big rise in bay waters happens during storm season. High tides and storm surges could send that higher water inland, flooding Highway 101 and neighborhoods along the bay. If the bay runs right up to the edge of development and we build sea walls to protect property, then that deep pool of water will have much higher waves, stronger currents and will pound the shoreline much harder than where there is now graduated wetlands. The effect, experts say, would be similar to what happens when you churn up water in a bathtub, and the wave energy quickly builds up and spills over the sides.

Part of the challenge in BCDC’s design competition is to come up with barriers that might absorb some of the power of those waves, instead of simply deflecting those waves with straight walls.

Home designers and constructors are realizing that all houses are organic.

The California Energy Commission asked the Davis Energy Group in Sacramento to evaluate new home construction in California a few years ago. The following excerpt from Home Energy Magazine tells you what they found.
The increasing architectural complexity of new homes requires greater vigilance on the part of framers, insulators, and drywall contractors to create a single thermal/pressure boundary between conditioned and unconditioned spaces. The more complex the design of the home, the more coordination is needed among the various members of the design team. Yet, mechanical contractors are rarely consulted regarding the integration of ducts and HVAC (heating, ventilation, and air conditioning) equipment into the house design. Contractors often lack both the knowledge and the time to implement house-as-a-system construction concepts. In addition, there is not an adequate infrastructure in place to provide contractors and installers with necessary training and certification.
House-as-a-system, or whole-house design, requires an integrated approach to water management. When I visited Japan, I went inside elegant buildings that were centuries old and made almost entirely of wood. Japan has a prolonged wet season, much like the northern coast of California. Because of this, the roofs of the Japanese houses I saw were designed to move moisture away from the structure. Inside, the buildings were well ventilated with the wood framing members exposed. Wood absorbs water during the wet season and dries during the dry season, allowing these healthy buildings to breathe in and out like other organisms.
In previous centuries, building homes was a craft learned primarily through apprenticeship with a master builder who knew how to create a whole house that worked in the wet, dry, humid, hot, cold, and/or windy climate in which it was built. Today, however, the home building industry is fractured, with designers and general contractors and several trades doing their parts and not always talking to each other. In order to build a house that works, all the players need to know how what they do individually in a house effects what everyone else is doing as well. Plumbers have to respect air and moisture barriers, designers have to understand moisture dynamics, and HVAC contractors have to understand the pressure dynamics of the whole house; otherwise furnaces will backdraft, mold will form in walls, homes will have poor indoor air quality, they will cost a fortune to operate, be very uncomfortable, and fall down after a few years.
In order to combat global warming and provide affordable housing to everyone who needs it, houses must be designed, built, and retrofitted to be energy efficient, healthy to live in, affordable, and made to last forever (or at least for a hundred years). Interested in being a part of the solution to global warming? Get a green collar job. In particular, I would recommend a career in home design and construction to anyone with the time and energy to get the right kind of education, training, and experience. There is plenty of work out there and that's not changing anytime soon. Home Energy publishes a training guide for people in North America interested in learning the concepts and tools of whole building design and construction.
