Resilient design trend? Modern floodgates appear in vulnerable areas.
Walking along Flat Street in Brattleboro, Vermont this morning before businesses opened, I saw a sign that an important lesson about resilience had been learned over the past year. The floodgates were up in numerous doorways. Flat Street, as some readers may recall, lies in the floodplain of the Whetstone Brook, which angrily overflowed its banks in August 2011 during Tropical Storm Irene and created havoc for the small businesses, artisans, and restaurants located there. That event is pictured in a previous RDI post here. No one expected that flood. Yet, somewhat remarkably, the New...
Read MoreSea-level Rise, Storm Surges, and Delaware’s Resilience Challenge (with a Sandy update)
Update Note, October 30, 2012 With Post-tropical Cyclone Sandy still whirling around somewhere to my west, the article below feels prescient. It wasn’t of course – there was no advance knowledge of this particular storm – but what just happened with Sandy is well in line with climate change trends. It had been many decades since a hurricane of this magnitude made landfall in or near Delaware, but the conditions were just right, including record-high late-October ocean temperatures in the high 70s (F) to give the storm extra power as it crossed the coastline. Had Sandy...
Read MoreFundamentals of Resilient Design #7: Renewable Energy Systems for Emergency Use
House location and design are the starting points in achieving resilience—with such considerations as where the house located, how well it can weather storms and flooding, and how effectively it retains heat and utilizes passive solar for heating and daylighting. Beyond that, we should look to renewable energy systems for back-up heat, water heating, and electricity. In this blog I’ll review a few of these options. Wood stoves In rural areas, clean-burning wood stoves provide an easy option for back-up heat. With a compact, highly energy-efficient (resilient) home, a single, small wood stove...
Read MoreFundamentals of Resilient Design #6: Natural Cooling
A blog on cooling? In September? What gives? In my recent series of blogs, I’ve been laying out some of the basics of resilient design—which will become all the more important in this age of climate change. Achieving resilience in homes not only involves keeping them comfortable in the winter months through lots of insulation and some passive solar gain (which I’ve covered in the previous two blogs), it also involves keeping them from getting too hot in the summer months if we lose power and our air conditioning systems stop working. In this blog, we’ll look at cooling-load-avoidance...
Read MoreFundamentals of Resilient Design #5: Passive Solar Heating
When combined with a highly insulated building envelope, passive solar is the best way to ensure that a home will maintain livable conditions in the event of loss of power or heating fuel. As I discussed in my previous blog, a resilient home is extremely well-insulated, so that it can be kept warm with very little supplemental heat—and if power or heating fuel is lost, for some reason, there won’t be risk of homeowners getting dangerously cold or their pipes freezing. If we design and orient the house in such a way that natural heating from the sun can occur, we add to that resilience and...
