A lot of buildings are poorly insulated and ventilated - this can lead to overheating and winter deaths in homes .
Retrofitting is one solution to improving energy efficiency - we need more electric boilers and ground a d air source heat pumps .
Buildings
If we build more houses we will encroach on valuable green space .
Buildings are often powered by nonrenewable fuels .
We could build taller but this could come at a cost to the skyline and the size of homes .
Does everyone need a big house ?
We could promote living in smaller conditions , but those in cramped conditions would need more space still .
This is a big problem with an easy solution - solar panels on roofs , switching energy suppliers . But solar panels are not affordable for all .
Accress to green space in new builds could be made compulsory ( e . g ., for growing space and nature ).
