Instead of designing 8 metre extensions, how about voluntarily having a 2 metre limit; and foregoing the commission if the client insists on 2m? Would this help reduce excessive climate change?
I am retired, but have made a bit of money, etc. from construction over the years; so thanks construction industry; however: https://www.opendemocracy.net/en/oureconomy/britain-just-declared-climate-emergency-what-happens-next/ how does that sit with concreting over substantial areas of England?
https://www.newscientist.com/article/2203700-sea-level-rise-could-hit-2-metres-by-2100-much-worse-than-feared/ = reality. Every scientific report suggesting far, far worse outcomes that originally thought. What do I suggest to my near 14 descendants living in coastal Clacton; wait for 50 years for their existing social housing to get 150mm rockwool insulation grant? How would the climate sceptics converse with my wheelchair bound friend Trevor, a perfectly healthy early 1950's baby, who contracted polio as a result of the second order effects of the Canvey Island floods? This is very ordinary concern, from very ordinary people, or is Trevor a zealot?
Sorry Paul, but having been into construction since before 1969, and having experienced actual practical climate change in London since the early 1950's; I have to agree with Robert Sakula.
As a retired 66 year old I can remember thick ice on the inside of a single glazed E17 bedroom window circa 1957. In 2019 ice seems to have disappeared from next door E4. I estimate the average annual E4/E17 1950's to 2019 thermal comfort temperature rise to be in the region of 10 degrees C. I am not sure where 1.5 degrees C in the Paris accord comes from; are they using a different thermometer? The 10 degrees C is subjective and is due, in my opinion to a) climate change and b) in densely populated London comes from the the humongous urban heat island effect. Standing on a London Bridge platform in the last 3 months I was downhearted to realise that what I was looking up at (Shard) was to all intents and purposes a vertical greenhouse. PS can remember getting heavily into primary energy saving designs in the mid 1970's......
