DESS (District Energy Sharing Systems)

Through the continued work of DEC, a number of innovations and opportunities identified an integrated solution for community energy planning.  As such, the patented DESS or District Energy Sharing System technology was developed which allows for the sharing of energy between buildings on a low temperature hydronic loop thus enabling the optimization of water and energy resources through the recovery and distribution of thermal energy and water.  Projects such as Westhills (Langford), the Athlete’s Village (Whistler), and Marine Gateway (Vancouver) are tangible examples of this technological solution to energy sharing.

Innovative Technical Approach

Demand Side Management

The first step in reduction of community energy consumption is to minimize end use.  Demand side management, in terms of a District Energy Systems (DES), refers to reducing consumption directly and indirectly at the building level.  By first reducing the building demand we reduce the overall energy and water requirements of the community and therefore the capacity of the sources required to meet this demand.

Resource Recovery and Reuse

To the extent that the buildings do not balance their internal heating and cooling loads a source of energy is required.  To meet the heating and cooling source requirements we will first look within the community for resources that can be recovered and reused.

Fitness for Purpose

Fitness for purpose refers to delivering energy and water in the quantity and quality as required by the end user.  Delivering anything else is wasteful practically and economically.  For DES this means supplying the temperatures the buildings need when they need them, reducing the supply of unnecessary energy and minimizing line losses.
