DEC has pioneered and developed a patent pending district heating, cooling and water reclamation technology collectively referred to as a District Energy Sharing System (DESS) with the ability to reduce community energy and water consumption by up to 50%, construction costs by 30% to 50%, and greenhouse gas emissions by 50%. Many of the district energy innovations developed were driven from a financial model that demanded the adherence to four key principles for energy and water management, including demand side management, recovery and reuse, fitness for purpose, and optimizing the total lifecycle costs of infrastructure and community amenities.

DEC's district energy patent pending innovations are based on modern building system principles, making a DESS a logical extension of the building systems. The goal of modern building construction is to reduce the energy consumption of the building to net zero; this is typically cost prohibitive. By connecting a building to a DESS the remaining imbalance in energy consumption, heating or cooling, can be recovered and shared within the community. In addition, the DESS provides a means for clean effluent from water reclamation systems to be distributed within the community for reuse in non-potable applications. This allows developers and architects to reduce the individual costs of both new buildings and retrofits to existing buildings, while allowing the entire community to move towards net zero energy and water consumption.
