Energy Foundations Malcolm's expertise in developing and implementing sustainable and environmentally friendly foundation solutions is invaluable. Energy Piles are an innovative option to utilize the deep foundation elements to not only support the building loads, but to also harvest energy for heating or cooling. By exchanging thermal energy between the ground and the building, the piles and their integrated geothermal loop system can be utilized as a ground source heat pump. At Google's newest campus, Malcolm installed the largest integrated geothermal pile system in North America.
