We've all heard about solar PV panels, but that's not the be-all and end-all of technologies which could make buildings more efficient and less harmful to their environments. May I ask what else have folks got up their sleeves?

Dimensions of environmental friendliness

All good technical discussions start with a host of term definitions and context statements, so I'll attempt to start this one off on strong footing! I figure that anything which checks one or more of these checkboxes (reasoning included) works, but please feel free to colour outside of the lines -- this is just a kicking off point. Note that anti-ticking a checkbox is fine; everything has trade-offs, and sometimes paired solutions can negate each others' downsides. Magnitude is always a factor, too, since this field is rarely black and white.

(no need to bring receipts, mind; I'm sure we can keep this light hearted so as to avoid digging into comparative EPD critiques :3)

• Low embodied carbon (the kgCO2e emitted per a cradle-to-grave analysis (EPD, often) of a product),
• Low operational resource consumption (anything which works as well as an inefficient equivalent, but uses less energy/consumables -- LED vs. incandescent bulbs, heat pumps vs. nat gas furnaces, insulation vs. no insulation, etc.),
  • Includes water conservation, too!
• Durability over design life (per the Canadian Wood Council (they're ... a little biased), the median service life of buildings is <90 years, so adjust amortization periods accordingly),
  • Includes things like wildlife-urban interface-safe materials, as well as clay bricks and whatnot.
• Sustainability (if we can't do it for more than a century, let alone a few decades, it's probably not worth the sunk costs),
• Low environmental toxicity (no point trying to save the environment if it's all a toxic swamp afterwards),
• Supportive of local ecology (built environments tend to be biodiversity deserts -- cobblestone boulevards, brick walk ups, and tin roofs are hostile everything but pigeons and rats. Think native planting, green retaining walls, planted pavers, etc.).

(full disclosure: I'm probably going to borrow several of these at some point, so this is a half-discussion, half-I'm-outsourcing-my-research post 😅 hopefully that's acceptable ...)

This is a recurring post to discuss programming or other technical projects that we've been working on. Tell us about one of your recent projects, either at work or personal projects. What's interesting about it? Are you having trouble with anything?
