MAPPING GOALS

The purpose of the community energy and water mapping project is to:

Integrate energy (electricity and natural gas), water and demographic information into a single database;

Aggregate and map data in order to help municipal staff, utility staff and stakeholders to better understand community energy and water consumption; and

In turn, help to implement demand management programs and inform long term conservation goals

Characteristics of Housing Stock

Structure data helps to understand the built form characteristics of energy use

Nearly half of all electricity and natural gas consumed in Burlington is used in residential buildings

Residential energy use is affected by regulation (OBC), the market (building size), occupant behaviour and preference

Infill development and retrofit opportunities will outweigh new build in Burlington

The biggest gains are likely to come from infill, retrofitting existing housing stock, behaviour modification of occupants

Nearly half of housing units in Burlington were built before 1980

More than half of units are between 1,500 and 2,500 sf

4 COMMUNITY ENERGY METRICS

Total energy use (GJ)

Energy use per heated area (GJ/m2)

Energy use per household (GJ/hhd)

Energy use per capita (GJ/cap)

Trends in Residential Energy Use:- Newer homes in Burlington are generally more energy efficient

- Homes built in the 1980’s and some built in the 1990’s are larger and therefore use more energy per household and per person

- While homes built after 2005 are large too, they are energy efficient and use less energy per household and per person

- Compact, efficient homes use the least energy

Gas use is lower in new

homes16

Summary:- This work helps form a baseline which can be used to establish community

energy targets and timelines

- ICI mapping can be used to support CDM/DSM implementation but we need better validation between Burlington Hydro, Union Gas and MPAC

- Enables spatial tracking

- Areas of high energy use; areas of growth

- Monitoring of performance and progress

- This work also can be used to explore future development scenarios and to help identify opportunities for conservation and retrofit

- Land use policy (infill, zoning)

- Programmatic responses (LICs, CDM/DSM programs)

- Next step is to overlay with demographic information and consumer attitudes using the Environics Analytics information to design retrofit and conservation programs
