If we are looking for quick and substantial energy savings for existing buildings, then local heating systems deserve our closest attention
Radiant and conductive heating systems make energy use independent of the size of a room or building.
Most modern heating systems are primarily based on the heating of air. This seems an obvious choice, but there are far worthier alternatives.
Cooling people by increasing local airflow is at least ten times more energy efficient than refrigerating the air in a given space.
The arrival of compact lithium-ion batteries has increased the performance and diversity of electrically heated clothing.
Modern research, which combines ancient knowledge with fast computing techniques, shows that passive solar cities are a realistic option, allowing for surprisingly high population densities.
Modern thermal underclothing offers the possibility to turn the thermostat much lower without sacrificing comfort or sex appeal.
Oven stoves are greener, more efficient, healthier, safer and cosier than all modern heating systems. Why are they gone and how do we get them back?
