How To Make North American Homes Climate Friendly

Everyone is well aware that low density, sprawling, and energy inefficient is bad for the planet. Years of mindless development have left us with homes which are not well built for the current climate. It’s imperative that we get these homes to be climate friendly, here’s how. The Guardian has a nice article on the various ways people can convert their inefficient housing into a climate-friendly structure.

Deep reductions in emissions will involve revamping the major appliances in the home, such as the water heater, furnace and air conditioning unit. As these items become older, they become wasteful and they will need to be replaced by more efficient appliances that run off clean electricity.

Some of these replacements will be relatively innocuous, such as the installation of heat pumps, which will be in the basement or on the side of the house. Heat pumps work on principles similar to a refrigerator, shifting heat from outdoors indoors and vice versa. They can heat and cool your home and can also heat your water with an efficiency rate four times greater than a gas-powered version.

Want Better Communities? Get rid of Homeowners

- Adam Clare

The North American dream often hinges on owning the shelter you reside in, but with raising home prices this is a challenge for many. It may work out in the long run though as we should be creating systems that favour renters over owners since homeowners tend to hold back progress. Of course, we will need to protect renters from evictions and so on. Regardless, over at Vox they have an interesting analysis on home ownership which is worth considering:

Researcher Rachel Bogardus Drew points to more than a century’s worth of messages praising the benefits of homeownership, “everything from personal freedom and self-determination, social equality and inclusion, personal and economic success, and a better quality of life.”

One of the messages Drew cites is from a 1916 article in the Hutchinson News telling readers: “Owning a home raises one in the estimation of his neighbors and associates. … Nothing gives a man a better standing in a community than the fact that he is a house-holder, a payer of taxes on real estate.”

The Suburbs Are Bad, Here’s How to Make Them Good

We need to change the way we build and live if we’re going to avert catastrophic climate change, and it’s time we think about the biggest carbon offender: the suburbs. Suburban living is car-centric, energy intensive due to the design of the houses, more expensive to maintain due to low density, and embodies other problematic issues. It may sound like a daunting task to switch the suburbs from an unsustainable system to a sustainable one, but that’s exactly what people are trying to do.

According to new research published last week by Teicher and two colleagues, if the trend away from downtown cores continues, it is essential to urgently refocus some of the effort to fight climate change from cities to suburbia.

While the authors still believe urban densification is better for the environment, their paper — titled Climate Solutions to Meet the Suburban Surge: Leveraging COVID-19 recovery to enhance suburban climate governance — addresses the reality that in both Canada and the United States, the trend toward sprawl will be hard to stop.

The only pragmatic solution, Teicher said in an interview on Friday, is to develop policy to mitigate the worst impacts of suburban and exurban sprawl.

Manage the Summer Heat in Your Home Without AC

- Adam Clare

Global warming is making our cities hotter than ever before, which has led many to turn on the air conditioning. The irony is that to keep us cool we turn on machines which consume a lot of energy, and if that energy comes from a non-renewable state then the local cooling ultimately adds to global warming. Fortunately, there are simple low-cost ways to keep you cool in the summer heat while you’re indoors. Over at Popular Science they’ve put together a handy guide.

A lot of warmth comes into your home via sunlight. In individual rooms, you should control these rays with blackout curtains or shades. If you still want sunlight, open the curtains on windows that don’t face the sun directly; this allows indirect sunlight to filter in.

The color of the curtains’ outward-facing side also matters. We see color because that particular wavelength of light bounces off an object. Because heat radiates as infrared light, “hot” colors like red, orange, and yellow will deflect the most warmth.

Of course, not everyone enjoys living like a vampire. If you need more direct light, consider solar screens and window tints instead of curtains. These treatments can remove certain wavelengths of radiation while letting others in.

Architects Need to Build Their Knowledge to Build a Sustainable Future

Current popular building practices lack a nuanced approach to sustainability due to years of it being culturally ok to put future generations into ecological debt. Thankfully, things are starting to change and architects want to build a sustainable future, and fast. Prior to mass industrialization buildings were constructed using locally sourced materials, making them more sustainable with a relatively small carbon footprint. As globalization increased the techniques of using local materials were forgotten and now architects are calling for everybody in their field to share best practices around locally sourced material and techniques.

Architects are at the forefront of our drive to lessen the impact humans have on the environment. While the agenda has stayed relatively constant since I was at school, the sustainability goalposts have moved – and narrowed. A building designed as zero-carbon just half a decade ago would now be considered ‘operationally’ zero-carbon at best, whereas ‘whole-life carbon’ calculations now consider the building’s demolition and waste disposal. Our thinking, designs and architectural goals must evolve, but things are evolving at such a speed; how on earth are architects to keep up?

‘Renewable and sustainable technologies change very quickly, as does our understanding of sustainable outcomes, so it is important to try to keep on top of it,’ says Tate Harmer partner Jerry Tate. ‘We need to communicate to each other in our industry, sharing best practice and our experiences to help get to the right answers.’
