Rebuilding GREEN after the Tubbs Fire
Surviving homes, gas flares, toxic materials
By Ted M. Tiffany
After the fires, our normal greetings were replaced by three quick questions to our friends and neighbors we encountered in the next month after the fires: How are you? How’s your family? Did your house make it? The varying responses, hugs, and connections made with former acquaintances that became neighbors and friends changed our concept of community. We all faced some level of shock, terror, and sustained fear for those weeks following the initial event, which for most was slowly replaced by grief, acceptance, and motivation to do something productive.
Out of this need formed the Rebuild Green Coalition (RGC), a group of experts that have dedicated their lives to building sustainable buildings and communities, and setting standards for the industry such as LEED, CALGreen, and the Living Building Challenge. The RGC members saw a need to help homeowners rebuild in a smart, healthy way, without adding to the already expensive price tag for rebuilding — we have all experienced the fascinating way that smart, green design, if done right, can actually reduce costs with efficiency gains.
Many of those affected by the fires, and the majority of those coming into the area to help, use the word “opportunity” in the context of how we will rebuild. We used that word, too, but after talking with many people who lost their homes we’ve replaced it with the “imperative” to act consciously and thoughtfully in this rebuilding effort. We owe it to those who lost lives and homes, and are struggling to reinvent their lives, to produce a better outcome through our efforts.
The influx of offers to help has been incredibly heart-warming, it has also placed some burden on the homeowners and local officials – to figure out what to do with all this help, what is good and bad help, and where to apply it most effectively. For homeowners who have never built a home in their life and are now thrown into a process that most never attempt, information overload is a huge problem. Many of us in the green building movement have taken a lifetime to build knowledge and abilities to bring it to bear in this moment, for those that lost their homes. Green and healthy isn’t just for the well-to-do or the perfectly insured, it’s a human right we need to bring to the rest of the community, well beyond this rebuild effort that will occupy us for the next few years.
In many planning meetings since the fire, we’ve come across some incredible tales of homes that survived, studied those cases, learned from them, and have a need to share those lessons. Some homes spared were in fact miracles that defy logic; others that were protected by vineyards or good defensible space make sense; and yet some were designed to survive, yet didn’t. David Arkin, of Arkin Tilt Architects, who specializes in green construction, had two straw-bale houses survive the fires: one in Sonoma and the other in the Redwood Valley in Mendocino. Designed with natural, regional, and sustainable materials, they are great examples of green construction, but also healthy survivors with lessons learned: metal roofs and high-performance sealed attics helped in their survival. Even if they did burn, these buildings wouldn’t be toxic ash heaps; that in itself is another lesson – we should strive to use more natural materials that are safe for the families living in the homes and, in the worst case, safe for our firefighters.
Time for a Change of Fuels
RGC members have talked a lot recently about eliminating the need for natural gas in new homes. With clean, safe, and efficient electric heat pumps available for heating and cooling, the need for natural gas space heating has virtually disappeared. New efficient water heaters, called air-to-water heat pumps, offer similar gains for the electricity argument. Gas ranges now represent the last stronghold of natural gas in the home – largely due to memories of unsatisfactory experiences cooking on old-style electric ranges. However, induction stovetops and electric convection ovens not only have been proven to cook faster, more evenly, and more safely than their gas counterparts, these newer technologies have also won the hearts and minds of many initially-skeptical cooks, including professional chefs.
Natural gas combustion furnaces, water heaters, and cooking appliances in the home have complicated indoor air quality for decades, with silent carbon monoxide poisoning claiming hundreds of lives each year. There is a better way – with all-electric homes that eliminate combustion and really only require carbon monoxide sensors to prevent vehicle exhaust from entering the home (a risk that can be eliminated entirely with detached garages or carports, and/or electric cars). After the fires subsided, it was disturbing to see gas flares such as the one pictured above, still burning when the combustible materials were all exhausted; the natural gas supply could not be turned off, and that fuel – which new, safe and efficient technologies have made completely unnecessary – kept the flames going.
