Glass and concrete buildings with floor to ceiling windows are becoming increasingly common. They look good even though they are cheap to build. Trouble is that they are extremely inefficient when it comes to heating and cooling and already in temperate zones they require a lot of energy to power the air conditioning. If you make an internet search with the keywords grant building insulation you will see that a lot of governments, around the world, are taking action on old buildings, but they do nothing about new buildings. Things got to the point that a country like Japan is facing an energy crisis due to a heatwave. I know that glass panels used in these buildings have double glazing with an insulation layer, but that stops conductive heat, not the radiant heat coming from the Sun.
Regulation about energy efficiency of new buildings already exist in a lot of countries, but they are not preventing builders from building giant glasshouses to live or work in. Has the problem ever been addressed? Could some kind of legislation put a limit or is it something for which builders could always find technical workarounds?
I see that the question was closed alleging that the purpose of the question was to discredit the use of glass. But I was simply talking about the excessive use of glass in modern buildings. Some users stated in the comments that the use of glass can be tuned to match the energy requirements. But in reality when I look around I can see that a lot of new building under construction have the entire façade made of glass and without any trees in front to provide any shielding. There might be buildings that went through a careful analysis of the energy requirements, but I can bet they are only the most expensive ones.
Other users stated that glass is not so inefficient, but definitely it cannot match an opaque panel covering an insulation layer, there is no tint or gap filled by inert gas that can totally block the radiant heat passing through, and I repeat that I am not criticising windows, but the excessive use of glass.
