Work Completed
The Community Energy Association (CEA) conducted a district energy prefeasibility study of Township of Langley in March – April 2009.
A district energy prefeasibility study is an initial survey of district energy options within the Township, in order to determine the potential scope of district energy
CEA conducted a review of existing and projected energy demands across the Township, a review of potential energy sources , a visit to potential district energy sites, interviews with key people, a discussion with a panel of experts and identification of best project opportunities

Designing for District Renewable Heat
Encouraging mixed-use higher density urban development;
Reducing the energy input required for a given level of service;
Matching the type of energy with its use;
Managing surplus heat across applications and sectors;
Avoiding waste by converting to energy;
Integrating on-site renewable sources of energy;
Use of grid energy as a resource to optimize the overall system and ensure reliability

District Heat Opportunities
Applying filters of density, variability, and availability…
4 areas where the heat demand looks promising for renewable district energy

Energy Everywhere
Different energy options for different areas…matching the source and system to the local availability and need
Distributed building-scale renewable heat, not inter-connected but widely deployed

Poor Not a good candidate unless site floorspace density increases Rabtherm, sewage lift station New Fair Poor Carvolth potential urban village Possible Compact, single-use, near large sewage lift station. More nearby heat demand opportunities likely needed to justify a DE system Sewage lift station New Poor Good Potential high density Willowbrook development Possible Energy density for space heating and hot water seems too low, although some individual buildings may show an opportunity Wastewater treatment plant Existing Good Poor Northwest Langley Industrial Area Good Mixed-use high density town centre redevelopment. New nearby large lift station about to be built should be designed to be “heat recovery ready” Sewage lift station, & possibly ice arena waste heat, OR wood pellets New Fair Good Downtown Aldergrove potential densification Good Compact, mixed-use, next to large private ice arena Ice arena waste heat with borehole, OR geoexchange New Fair Good Colossus potential mixed-use development Good High demand, new construction, new large sewer line nearby Potential combination of Rabtherm, vertical loop geoexchange, & wood pellets New Fair Good Yorkson Town Centre Good Institutional core of demand with carbon neutral requirement, few buildings to connect up Vertical loop geoexchange Existing Good Good Murrayville Core including hospital lands Overall Notes Best Heat Source Type Heat Stability Heat Density Location

Recommendations
Approve the development of a Murrayville core district energy implementation plan by staff and/or consultants as a first step towards a Murrayville district energy pilot project
Ensure Community Energy and Emissions Plan specifically supports district energy in high-potential areas and building-scale renewable heat in low density areas
Allocate budget to proceed with a feasibility study for the Murrayville site including further analysis of ownership / governance options
Contact BC Hydro and Terasen regarding financial support for the study

Going Further - Recommendations
Review policies to support building-scale renewable energy in low-density areas
Investigate greenhouse and anaerobic digestion opportunities
Provide training opportunities for developers on renewable heat opportunities
