Which Buildings are Bad for the Environment?
Old buildings
Aged roofing and damaged windows means heat can escape ("surge out of") them
Government offices, school and healthcare centres represent 1% of total buildings but contribute to 11% of building heat demand in London
Become so enegery intensive because they've been retrofitted to fit our modern day practices
Skyscrapers
Total emissions from high rise buildings can be twice as high as low-rise
Skyscrapers are wrapped in glass causing overheating during the summer
Many buildings have become dependent on mechanical ventilation and air conditioning which results in a high energy consumption
Tall buildings also take large amounts of energy to build and maintain (transporting and manufacturing materials/ on-site emissions, ect.)
Strategies already implemented in London's skyscrapers
Cheesegrater - has blinds that respond to the sun's movement
Gherkin - maximises airflow
Walkie Talkie - has a large green wall that boosts biodiversity
Homes
91% of buildings in London are domestic and contribute to the largest proportion of greenhouse gases
Many homes are old so not well insulated
This is an issue many climate activist protest about
Solutions for more sustainable homes
Government funding for more energy efficient practices (hard to meet targets)
High air-tightness in homes
Well insulated homes
Double and triple glazing
Using air-source heat pumps
Solar panels on roofs
