Fundamentals 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...

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...

I thought a lot about resilience last year, during a six-week sabbatical bike ride through the Southwest. I covered a little over 1,900 miles, most of it over land that hadn’t seen a drop of rain since the previous fall; some of those areas—mostly in Texas—still hadn’t received significant precipitation months after my return home.
