General Questions

  • What should I do if I am the victim of unsolicited phone calls or of a fraudulent door-to-door campaign?

The Government of Québec would like to remind you that it does not use telephone solicitation or door-to-door campaigns to promote its energy efficiency programs.

It would like you to remain vigilant should you be contacted by someone trying to offer you services or products in this field on behalf of, TEQ, the Ministère or of the Rénoclimat, Éconologis or Chauffez vert programs. If you believe you are a victim of fraudulent solicitation, this is what you can do:

  • File a complaint with the Office de la protection du consommateur
  • Call your local police department.
  • Register your telephone number on the National Do Not Call List by dialing 1 866 580-DNCL (3625) or by visiting lnnte-dncl.gc.ca. In doing so, you should not receive calls from telemarketers any longer.
  • Contact the Canadian Anti-Fraud Centre at 1 888 495-8501 or visit the antifraudcentre.ca.

Telephone scams are a method used quite commonly by ill-intentioned people. Their objective can be to sell products under pressure to other persons or to lead them to reveal personal information. These scammers voluntarily assume the identity of persons who work for renowned companies in order to obtain information from people who believe they are dealing with real employees.

If you have further questions about our programs, please contact the customer service department of Transition énergétique Québec.

  • Why is it necessary to have two energy evaluations?

Two energy evaluations are necessary to measure the energy efficiency of your home and establish it its energy rating was improved after the work was conducted.

Each evaluation is conducted by a Rénoclimat energy advisor and includes a blower door test.

  • The first energy evaluation serves to determine the ÉnerGuide rating of your home before the work starts. 
  • The second energy evaluation serves to validate the work that was carried out and determine the ÉnerGuide rating of your home once the work is completed. 

When both results are compared, it will be possible to observe if the ÉnerGuide rating of your home increased or not. It will also determine if you are eligible for financial assistance.

It is even possible to ask for an additional evaluation for any work that is carried out after the second evaluation.

Learn more about the energy evaluation process.


This information has been helpful?  Your feedback

  • Is there a time limit to carry out the work?

Rénoclimat does not set a time limit to undertake your renovations.

  • To receive the financial assistance to which you are entitled, you must have carried out all the phases (including the post-work evaluation) before the end of the program (March 31, 2021). This means you really don’t have to rush to finish your work and request a post-work evaluation!
  • It is not mandatory to carry out all the work recommended in the report produced by the advisor in order to receive financial assistance.

This information has been helpful?  Your feedback

  • What is the ÉnerGuide rating?

The ÉnerGuide rating is the energy efficiency measurement of your home. Energy efficiency is measured on a scale from 0 to 100. The higher the rating, the more energy efficient your home is.

The ÉnerGuide rating is based on the results of the blower door test and on the characteristics of your home as collected by an accredited energy advisor. The rating is produced using energy simulation software.

To find out more, consult the chart of ÉnerGuide rating examples


This information has been helpful?  Your feedback

  • Why can’t the work start before the first evaluation?

It is important for the Rénoclimat energy advisor to be able to evaluate and measure the exact energy performance of your home before the work starts.

The purpose of the blower door test, which is performed during evaluations, is to determine the airtightness of your home by measuring the rate of air flowing through a ventilator installed for this purpose. If you have already started the renovation work, the test will be falsified because it may not reflect the regular airtightness of your home. That is why it is important to wait for the Rénoclimat energy advisor to visit your home before starting any work. Otherwise, Transition énergétique Québec will not grant you financial assistance for your energy-based renovations.

Heating

  • Should I have a heating system with more output capacity?

More output capacity is not synonymous with efficiency. If your unit is too powerful, it will stop and start over more often, which means it will consume more energy, cost you more and even lead to discomfort.

However, output capacity should be considered because a new system will be more energy efficient. You need the unit to provide the quantity of heat required to ensure comfort in cold temperatures.

By being more energy efficient, your system will help you consume less energy while supplying the same quantity of heat.


This information has been helpful?  Your feedback

  • What type of output capacity should my heating system have?

The system’s output capacity (generally expressed in BTU/h or kWs) must be consistent with the real heating needs of your home.
 
It is impossible to determine the real required capacity of the heating system without relying on calculations.

The calculation mainly evaluates the heat loss of the home in order to establish the required capacity of the heating system. The calculation must be based on CAN/CSA F-280 standard known as Determining the Required Capacity of Residential Space Heating and Cooling Appliances.   

Many variables must be considered:

  • surface area and volume of the home;
  • layout and orientation of the home;
  • geographical location;
  • type of construction;
  • insulation and air/water tightness levels;
  • size, type and orientation of windows;
  • etc.

It is important to mention that the calculations used nowadays have been improved and do not solely take into account heat loss but also consider recent climate data. Computerized simulation tools are also increasingly used. Do not hesitate to ask questions and request a copy of these calculations.

To adequately calculate your heating needs, ask for a heating professional that is certified by the Corporation of Master Pipe Mechanics of Quebec (CMMTQ). We suggest that you call on more than one professional to help you verify and validate the results.

  • What is dual energy?

Dual energy consists in combining two sources of energy to supply a heating system.
 
Electricity is usually used as the main source and fuel oil or gas as the auxiliary source. Electricity is used during the major part of the heating season and auxiliary heating (fuel oil or gas) automatically takes over when temperatures drop (-12 ºC or -15 ºC according to the region). Users can take advantage of better rates, such as the Rate DT offered by Hydro-Québec. This preferential rate also applies to the entire electricity consumption of your home.
 
The main advantages of dual energy are that while you can enjoy a reduced rate and play a part in reducing greenhouse gas emissions, dual energy also leads to the optimal management of the Quebec hydroelectric network by reducing the intensity of the need during periods of peak demand in cold temperatures.

Air Conditioning

  • How to calculate the operation costs of a window-mounted air conditioner?

The following factors must be taken into consideration when calculating the consumption of your air conditioner:

  • output of your unit (generally in tons or in BTU/h);
  • performance of your unit (see EER (energy efficiency ratio) on the Energuide label of your unit);
  • use (number hours/day and number of days/year);
  • temperature setting;
  • weather conditions of your region;
  • your electricity rate;
  • etc.

Here are some tools to help you calculate the consumption of your air conditioner:

  • Should I use a central air conditioner or a heat pump?

You would like to cool your home but are hesitating between these two systems. Start by evaluating your heating needs!

A central air conditioner will only cool your home while a heat pump will air condition your home in summer and be used effectively to meet some of your heating needs. Thus, if you plan to replace or convert your current heating system, it would be profitable to consider buying a heat pump.

Before you reach a decision, take the time to evaluate and compare the advantages, savings and costs of these two options.

We would like to remind you that a high efficiency appliance that is ENERGY STAR® certified and features the output capacity that is suitable for you will help you save energy.

  • What type of air conditioner should I choose?

Before you buy an air conditioner, take the time to evaluate your needs and check… if you really need air conditioning!

Air conditioning leads to significant electricity consumption on hot summer days. Do not hesitate to consider other methods to keep your home cool before deciding to air condition your home.

Would your comfort requirements be satisfied by installing air conditioning in one or two rooms? An air conditioning unit could be what you need. Do you want your entire home to be air conditioned? Then a central air conditioner or heat pump would meet your requirements.

Whether you choose a central, window- or wall-mounted conditioner or a heat pump, it is best to select ENERGY STAR® certified energy efficient models which offer the best energy efficiency rating. These units or systems will help you consume less electricity, save money and preserve the environment.

Take the time to gather all the information you need to learn about air conditioning before you make your choice. Here are a few helpful links:

Regulations

  • Where can we find the regulatory requirements for buildings in Québec?

The regulatory requirements aimed at energy efficiency in buildings are contained in the Regulation respecting energy conservation in new buildings (c. E-1.1, r.1) arising from the Act respecting the conservation of energy in buildings (R.S.Q., c. E-1.1, amended by S.Q. 1983, c. 9).

The regulatory requirements aimed at the other aspects of buildings are contained in the municipal construction regulations and in the Québec Construction Code (CCQ) (B-1.1, r.0.01.01).    

The Régie du bâtiment du Québec administers laws and regulations in buildings and adopts a construction code that is applicable to Québec. For more information, consult the List of laws, regulations and codes administered by the Régie du bâtiment du Québec.

Finally, to check the building codes and standards that are in force in your municipality, contact your municipal building inspection department.

  • Amendment to the Construction Code

A regulation aiming to amend the Construction Code for the purpose of introducing new energy efficiency requirements for residential buildings was published in the Gazette officielle du Québec on February 22, 2012.

The terms of inspection of the proposed regulation will be determined and applied by the Régie du bâtiment du Québec (RBQ).

You can obtain a more detailed version of this draft regulation on the Web site of the RBQ at: http://www.rbq.gouv.qc.ca/lois-reglements-et-codes/projets-de-reglement/en-processus-dadoption.html (in French)

  • Why increase the energy efficiency regulatory requirements for houses?

Energy consumption has a significant incidence on the budget of Québec households. Quebeckers deal with high energy costs, particularly those associated with heating their homes. Energy consumption also has an impact on energy supply during peak periods, on certain forms of energy and on greenhouse gas emissions. Therefore, it is worthwhile to find out ways of reducing consumption as many possibilities present themselves to achieve this goal.

The most effective one, as well as the least costly for consumers, is to make sure that their dwellings are energy efficient, this means as early on as the construction phase.

That is why Québec is regulating the energy efficiency of buildings and proposing stricter regulatory requirements.

As a result, a draft regulation aiming to amend the Construction Code to introduce new energy efficiency requirements for residential buildings was published in the Gazette officielle du Québec on February 22, 2012. These requirements would enable Quebeckers to reduce their energy bills.


This information has been helpful?  Your feedback

  • Which buildings are targeted by the regulation?

The regulation targets new buildings and enlargement work performed on residential buildings, such as single-family and multi-family dwellings, that house only dwelling units and their subsidiary occupancies, have a building area not more than 600 square meters and a building height not more than three storeys.


This information has been helpful?  Your feedback

  • What are the regulatory requirements?

The regulation increases the energy efficiency requirements of new houses and dwelling units by improving the insulation of the roofs, walls and foundations, by increasing minimum requirements for doors and windows and by requiring the installation of ventilation systems that use heat recovery ventilators (HRVs).


This information has been helpful?  Your feedback

  • How were these requirements established?

The new requirements are inspired by the current Novoclimat program for new homes which has been operating since 1999 and has certified more than 17,000 housing units.

These requirements were also the subject of techno-economic evaluations to determine the levels of feasibility and profitability for the consumer as well as validations from different members of the construction industry collected during advisory committees, meetings and presentations.


This information has been helpful?  Your feedback

  • If the regulatory requirements are inspired by those of Novoclimat program, does this mean that all the new houses built in compliance with the regulation would receive Novoclimat certification?

No, Novoclimat certification is independent of regulatory requirements.

Transition énergétique Québec intends to continue improving the energy efficiency in buildings and is currently offering a new and improved version of the Novoclimat program.


This information has been helpful?  Your feedback

  • If the Construction Code requirements are inspired by the Novoclimat program, what will happen to this program?

The Novoclimat program continues to improve the energy efficiency in buildings. 

A new and improved version of the Novoclimat program was released on January 31, 2018.

And it is estimated that a new Novoclimat home enables its occupants to save 20% on energy costs in relation to a house that complies with the Québec Construction Code.

Ventilation

  • Natural or mechanical ventilation: what can I do to help my house breathe?

It is true that a residence must be well ventilated to maintain an appropriate level of humidity and ensure the health of its inhabitants.

In the past, houses were ventilated by simply opening the windows and doors and by counting the number of air movements (air infiltrations and exfiltrations) through the exterior walls. Still used in many homes, this method of ventilation known as natural ventilation is not always practical, comfortable or very economical.

For example, a residence that is naturally ventilated and has an air change per hour rating of 6 means that the total volume of air of this residence renews itself six times every hour. Imagine all the energy wasted in the winter to heat the cold air that is seeping into the house...and that doesn’t mean that the entire house is ventilated!

In an airtight home, the installation of a mechanical ventilation system helps control ventilation more adequately and improves the energy rating of the residence.

Since the mechanical system uses electricity, it is particularly important to select a ventilation system that helps recover heat and energy, such as a heat recovery ventilator (HRV) or an energy recovery ventilator (ERV).

Finally, it is important to remember that the installation of a mechanical ventilation system that sends fresh air into each habitable room through ducts is mandatory in new homes in accordance with current building standards and codes.


This information has been helpful?  Your feedback

  • What type of ventilation unit should I choose?

In terms of habitable space, the heat recovery ventilator (HRV) is the type of unit that ensures better energy performance. In point of fact, the hot stale air is ejected outdoors and used to preheat the fresh air coming in through the system; therefore, less energy is used to bring inflowing air to a comfortable temperature.
 
Generally speaking, a good HRV yields between 60% and 80% of sensible heat recovery efficiency (SRE) (using hot stale air) at –25 ºC. Look for a model that meets these criteria and is certified by the Home Ventilating Institute (HVI).

For more information, consult the Office of Energy Efficiency Website.
 
For bathroom fans, range hood fans and ceiling fans, look for ENERGY STAR certification. This way you can use products that consume less energy and make less noise.

  • In a home, does the HRV have to be on at all times, even in the summer?

It is advisable to adjust the settings of the ventilation system to reflect the season.

In the fall, winter and spring:

  • During the cold seasons, set the dehumidistat between 35 and 50% of relative humidity. This will automatically set off the system to prevent excess humidity.
  • When you are away from home, set the system to recirculation mode or to off (on the controller).
  • When you are at home, set the system to 20 minutes of air exchange with outdoors – 40 minutes of recirculation or 20 minutes of air exchange with outdoors – 40 minutes off.
  • When there are increased sources of pollutants (large group of persons, presence of smokers, etc.), set the HRV to high air exchange (max.) for specific periods of time.

In the summer:

Set the system to off (on the controller) and open doors and windows to ensure minimum natural ventilation.

In the summer, with an air conditioner:

  • When you are away from home, set the system to recirculation mode or to off (on the controller).
  • When you are at home, set the system to 20 minutes of air exchange with outdoors – 40 minutes of recirculation or 20 minutes of air exchange with outdoors – 40 minutes off.

At all times:

Activate the control device for the bathroom when using the toilet, bath or shower.

  • At what degree of humidity should I keep my home?

The optimal relative humidity of a home should be between 35% and 50%. It is within this range that air contaminants are less likely to proliferate (bacteria, viruses, mushrooms, moths, etc.) therefore helping to reduce the chances of developing health problems.

The degree of humidity tends to increase naturally with the various activities performed in the home such as cooking, baths, showers and the use of the clothes dryer. To maintain an adequate level of humidity it is necessary to use appropriate ventilation (by increasing the flow of the central ventilation systems, using bathroom fans and range hood fans) when using certain rooms or appliances.

  • In a home, does the HRV have to be on at all times, even in the summer?

It is advisable to adjust the settings of the ventilation system to reflect the season.

In the fall, winter and spring:
 

  • During the cold seasons, set the dehumidistat between 35 and 50% of relative humidity. This will automatically set off the system to prevent excess humidity.
  • When you are away from home, set the system to recirculation mode or to off (on the controller).
  • When you are at home, set the system to 20 minutes of air exchange with outdoors – 40 minutes of recirculation or 20 minutes of air exchange with outdoors – 40 minutes off.
  • When there are increased sources of pollutants (large group of persons, presence of smokers, etc.), set the HRV to high air exchange (max.) for specific periods of time.

In the summer:

  • Set the system to off (on the controller) and open doors and windows to ensure minimum natural ventilation.

In the summer, with an air conditioner:

  • When you are away from home, set the system to recirculation mode or to off (on the controller).
  • When you are at home, set the system to 20 minutes of air exchange with outdoors – 40 minutes of recirculation or 20 minutes of air exchange with outdoors – 40 minutes off.

At all times:

  • Activate the control device for the bathroom when using the toilet, bath or shower.
