General contractors and builders

For a general contractor or a builder, each decision is important because it can have a major impact on project costs. Gaz Métro and its team of new commercial building experts are gladly at your service to help you make informed decisions when it comes to energy.

Reduce your heating costs

For construction heating, the cost of natural gas is 30 to 50% less than propane. Choosing blue is very advantageous for your company. What's more, to heat your building permanently, over fourteen years, natural gas is less expensive than electricity, and over nine years, is more economical than oil.*

An overview of your consumption

Here is a simple formula to give you an idea of what your natural gas consumption might look like.

Example : For a 40,000 square feet building requiring temporary heat from January to March

  • Formula:  1/6 m3 x surface area (ft2) x duration (in months)
  • Consumption:  1/6 m3 x 40,000 ft2 x 3 = 20,000 m3

Note : This formula provides an estimate of your natural gas consumption and should be used for informational purposes only.  consumption may vary according to how temporary heating equipment is used.

Other benefits

In addition to economic savings, using natural gas offers other advantages on a jobsite:

  • Because natural gas is delivered by underground pipelines, the need to handle and manage tanks is eliminated
  • Reduces the risk of accidents on the jobsite
  • Reduction in the drying time of concrete and the panel joint compound
  • Reduction and control of the ambient humidity level
  • A monthly invoice is sent directly to your place of business, thus eliminating the need to manage delivery orders.

In three easy steps and by following our advice, see how to maximize your construction projects.

1. Communicate your needs as early as possible with a representative

It is essential to inform your representative of your heating needs right away. By filling out the "Natural Gas Request" form, you will provide all the necessary information to plan the connection for your project.

Construction heating only? It is possible to use natural gas for temporary heating, even if your project will not use natural gas permanently, by paying a fee installation and removal of the connection. These fees are evaluated by Gaz Métro's project technician. If the estimate for your consumption is sufficient, it is possible to avoid the fees.

2. Get credit approval (construction heat or permanent heat if you are the contract's signatory)

If you have no consumption history with Gaz Métro, you will be required to provide a deposit (or a bond or an irrevocable letter of credit from the last 3 years) in order to authorize your project.

Suggestion:  By always submitting your requests using the same company name, you will avoid this step in future projects.

3. Provide your DWG and floor plans for the building as soon as possible

The Gaz Métro project technician uses these documents to analyze the placement for the natural gas connection and begin working with your construction manager.

Suggestion: Submitting these documents as early as possible will ensure that you start the natural gas part of your project quickly and better incorporate the connection time necessary for Gaz Métro to plan its work – 6 weeks for a network project and 9 weeks for a network extension project.  Given these delays, installation charges may apply for winter projects submitted after mid-September. Plan ahead to avoid these wintertime costs by completing your natural gas request and submitting your DWG plan to your representative before September 15th!

An innovative solution for condo units


  • Comfortable warm air heating: warm air is diffused from high up on the wall opposite glass surfaces, not just from the ceiling. 
  • Quiet just like other warm air systems, according to our on-site test. 

Compact – Space gain 

  • Fan coil unit that controls heating + air conditioning positioned in ceiling space, freeing up cupboard space. 
  • Heat-generation system (boiler or water heater) may be coupled to fan coil unit in the condo. 
  • Reduction may be possible in number of diffusion vents + in false ceiling surface area = time-saving installation. 

Sized, installed and balanced by a professional 

  • System sized by a ventilation professional = guarantees it is functioning well. 
  • The same professional also ensures that there is a sufficient air flow and good air distribution in each room. 
  • This guarantees that the air flow diffused reaches the opposite glass wall. (Note: This is not a high speed system) 
  • There is no need to install electric baseboard heaters when the system is well-sized and well-adjusted.
