Climate change is one of the biggest threats we face today, as I wrote in a previous blog about ‘Zero-Carbon Buildings’. Clearly we need to reduce CO2 emissions globally to zero, or to less than zero, to address climate change. We need to approach this in two ways: radical energy efficiency to reduce demand and de-carbonisation of energy generation, in other words, a massive scaling-up of renewable energy generation.*
In some situations these two approaches are going to manifest as ‘Zero-Carbon Buildings’ or ‘Net-Zero Energy Buildings’. Even though there are many reasons why this is the wrong target (and if you read the comments you’ll find there are more than just the 9 reasons I wrote about.)
What then, is the best approach to achieving these notional targets of ‘Zero-Carbon Buildings’ or ‘Net-Zero Energy Buildings’?
Passivhaus First is the best approach and I explore why in this blog.
