Global Warming Graph

The temperature on the surface of the earth has risen consistently over the last 100 years.
Nearly all countries have agreed to try to limit carbon emissions
in The Paris Agreement of December 2015.
One way to tackle climate change is to reduce carbon emissions from heating buildings.

Interseasonal Heat Transfer (IHT) does this by recycling heat from Asphalt Solar Collectors down to ThermalBanks in summer.
IHT uses heat pumps to recycle heating back to buildings in winter without burning fossil fuels.
IHT doubles the Coefficient of Performance of the heat pump by starting from a warm ThermalBank.
