The District Energy Advantage

The Following are just some of the reasons to choose District Energy. Select a link below or scroll down the page to learn more.

Less Management - Less Costs

Buildings on district heating and cooling are simple to run! No boilers, chillers, or cooling towers. Less labour, maintenance, operating surprises and capital spending beyond budget. Fewer contractors in and out of the building. Less security worries, reduced administration and less headaches.

Lower Energy Costs

District energy is readily accessible, even in small amounts. Tenants receive heating or cooling as needed, after-hours, anytime of year and without the worry of seasonal shutdowns or switching from one service to another. Operational efficiencies are increased especially during shoulder months compared to conventional systems.

Lower Capital Costs

Whether the customer requires more heating or cooling or would like to install domestic hot water, District Energy Windsor can provide an instant response without the high capital cost for the additional energy generated.

Improved Operating/Maintenance Budgets, and Safety

By eliminating boilers, chillers and associated high pressure and temperature equipment, the property managers reduce their operations and maintenance costs, and at the same time increasing the building operating safety, eliminating noise and providing a better work environment for the staff. Major mechanical equipment is eliminated reducing the risk of breakdown and emergency repairs. Fewer operations personnel reduces the risk of labour problems. Less on-site chemicals reduces safety risks and the elimination of combustion fuels and refrigerants means reduced risk of being affected by changing legislation.

Stable, Competitive Energy Rates

District Energy Windsor uses ice storage technology to assist in providing the least costly chilled water. Ice is built during the off-peak electrical periods, generally night-time, then melted and circulated through the system during the high-peak electrical periods, during the daytime. This technology results in lower chilled water prices than conventional in-house chillers, which run when most buildings are occupied; during the daytime, and during high peak electrical price times.

Other technologies utilized in district energy systems could include a dual fuel source (gas and fuel oil) for the boiler system, whereby the most available, low-cost fuel can be used in the boiler system. Some district energy fuel sources can include waste heat from electrical generation plants, bio-mass-waste from wood products, and bio-gas-municipal solid waste systems.

Purchasing district energy is participating in the energy provider's business which in turn results in system expansion and aids in their purchasing power of electricity and gas and improved system efficiencies.

Increased Property Value

Physically removing the steam/hot water boiler plants and/or chillers will enable DEW customers to gain additional building space and eliminate noise from mechanical rooms. District energy equipment inside a building occupies about 1/5th the area of conventional systems. Stacks, cooling towers and associated environmental concerns are also eliminated.

All of this can enhance the property value.

Reliable Heating and Cooling Service

District Energy Windsor's system offers 24 hours a day, year round, operations and monitoring by professional stationary engineers. Strict maintenance schedules are adhered to and the plant is designed with backup capacity to provide a reliable, redundant system, ensuring that customer needs, including seasonal variations and peak demands can be met.


Reconfiguring interior space without the need for major HVAC retrofits when remodelling or expanding a building is easier and quicker with district energy heating and cooling. The DEW solution allows the customer to quickly add or remove heating and cooling capacity, without additional costly investment.

Environmental Benefits

By using DEW's services, the customers will have no concerns about compliance with current and future environmental legislation. Issues such as stack pollution, refrigerant emissions, greenhouse gases, architectural shielding of equipment, such as cooling towers, and others will no longer affect them.

Reductions in CO2, NOx emissions and particulate matter are realized with district energy systems compared to emission levels produced from standard in-house commercial boiler and chiller plants. Also, the number of cooling towers and plumes are reduced throughout the City Centre and fuel delivery and storage in individual buildings is eliminated.

Future Peace of Mind

Through DEW service, customers are not only avoiding having to budget for the replacement costs of chillers and boilers, but can also be assured that alternative energy sources and new technologies will be at their disposal. DEW is investigating incorporating innovative projects such as Combined Heat and Power and alternative fuels, into future plans for expansion. These types of technologies will ensure that its customers will always have an energy supply, at the lowest possible cost, with the greatest reduction in CO2.

What is Combined Heat Power (CHP)?

Combined heat and power - also known as cogeneration - is a way to increase energy efficiency in communities. Standard power plants effectively use just 40 percent of the fuel they burn to produce electricity. Up to sixty percent of the fuel used in the electricity production process ends up being rejected or "wasted" up the stack.

Combined heat and power uses this rejected heat, to heat buildings in a surrounding area through a district energy system. The efficiency gain results in a dramatic reduction in emissions.
