Work CompletedWork 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 HeatDesigning 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 HeatDistrict HeatOpportunitiesOpportunities

• Applying filters of density, variability, and availability…

• 4 areas where the heat demand looks promising for renewable district energy

Copyright 2007 Community Energy Association 9

EnergyEnergyEverywhereEverywhere

• 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

Notes Overall

Murrayville Core including hospital lands

Good Good Existing

Vertical loop geoexchange

Institutional core of demand with carbon neutral requirement, few buildings to connect up

Good

Yorkson Town Centre Good Fair New

Potential combination of

Rabtherm, vertical loop

geoexchange, & wood pellets

High demand, new construction, new large sewer line nearby Good

Colossus potential mixed-use development

Good Fair NewIce arena waste

heat with borehole, OR geoexchange

Compact, mixed-use, next to large private ice arena Good

Downtown Aldergrove potential densification

Good Fair New

Sewage lift station, &

possibly ice arena waste

heat, OR wood pellets

Mixed-use high density town centre redevelopment. New nearby large lift station about to be built should be designed to be “heat recovery ready”

Good

Northwest Langley Industrial Area

Poor Good Existing

Wastewater treatment plant

Energy density for space heating and hot water seems too low, although some individual buildings may show an opportunity

Possible

Potential high density Willowbrook development

Good Poor New Sewage lift station

Compact, single-use, near large sewage lift station. More nearby heat demand opportunities likely needed to justify a DE system

Possible

Carvolth potential urban village

Poor Fair NewRabtherm, sewage lift

station

Not a good candidate unless site floorspace density increases

Poor

RecommendationsRecommendations• 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 - RecommendationsGoing 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
