Custom software tools case study - performance of earth-air heat exchangers for Polypipe and WSP

Polypipe has developed a range of reinforced polyethylene pipes for use as earth-air heat exchangers. They and their partners WSP required a software tool to calculate the heating and cooling benefits of a heat exchanger made from the pipes, hour-by-hour using hourly air temperature data for locations across the UK and for a range of soil types.
