Frequently Asked Questions

Understanding Home Evaluations

What is an EnerGuide Label?

The EnerGuide label on a newly constructed home is the document which summarizes the home’s energy performance information from the EnerGuide home evaluation completed after the home was constructed. The EnerGuide label should be permanently posted in a visible spot in the home, for example in the home’s mechanical room or on the electrical panel.

The label includes:

  • Your EnerGuide rating – the modelled energy consumption of your home measured in gigajoules per year. The lower the rating, the less energy you consume.
  • A typical new house reference – the reference point that shows the estimated energy consumption of a home that is the same size, location and design as yours and built to the current new construction energy efficiency requirements of the National Building Code.
  • Breakdown of the rated annual energy consumption – a pie-chart breakdown of the major energy uses within the home.
  • Greenhouse gas emissions – the estimated GHGs emitted annually as a result of using energy in your home.

For a more detailed explanation see the Natural Resources Canada Guide to the EnerGuide Label for Homes.

When should I have an EnerGuide Evaluation?

There are two EnerGuide Evaluation Services for new homes. The pre-construction evaluation, which is completed during the design stage of the project, and the post-construction evaluation, which is completed once the house has been built.

Pre-Construction EnerGuide Evaluation (Construction Upgrade Service)

Contact a registered energy advisor to perform the pre-construciton EnerGuide evaluation  when you are in the design and planning stage of a new home project.

This service is especially useful when builders are trying to build to minimum performance levels as required by BC Energy Step Code, and other green building certification requirements.

Post-Construction EnerGuide Evaluation (Basic Service)

The post-construction EnerGuide service can be completed for a new home anytime after construction is finished up until it is six months old, based on the date of occupancy by the first homeowner.

What are EnerGuide home evaluations and what are the benefits?

An EnerGuide home evaluation for residential new construction is a comprehensive service designed by the federal government to help builders and developers understand how a home uses energy and what steps you can take to improve the building plans and construction process to maximize the energy efficiency of the home built. The service involves a registered new homes energy advisor assessing your home’s energy performance by collecting information on the following components of your home:

  • Size and geometry of your home
  • Type and efficiency of space and hot water heating systems
  • Insulation levels
  • Windows and doors
  • Ventilation systems
  • Air-leakage (using a blower-door test)

This information is used to generate a pre-construction and as-built EnerGuide rating for the home and a pre-construction builder upgrades options report to outline the options and opportunities to improve the efficiency of the home during the construction process. Registered energy advisors are building science professionals who provide unbiased energy saving information, rather than recommending any particular product.

The key benefits of consulting an energy advisor for your construction project are:

  • Energy Modelling to Improve Design – energy advisors conduct energy modelling to verify how much energy a proposed building is expected to use. Energy advisors also use energy modelling to provide detailed information on how each upgrade option to your building plans can improve the efficiency of the home you are building. This allows the builder to select the upgrade option that best suits the construction budget, the design of the home or the preferences of their clients.
  • BC Energy Step Code Verification Services – energy modelling can confirm the home meets the minimum requirements of the BC Building Code or any step of the BC Energy Step Code. Registered EnerGuide Rating System energy advisors are authorized to provide builders with the service to complete the BC Energy Compliance Report for Part 9 buildings complying with Subsection 9.36.5. or 9.36.6. of the BC Building Code.
  • Access Incentives – using a registered energy advisor can support you to access financial incentives and rebates for building to a higher level of construction. Check out the incentive search tool for information about incentives and rebates.
  • Access a Home Energy Label – a home energy label is an information tool, produced by a trusted and recognized third-party, and designed to provide consumers with recognizable and comparable information about the modeled energy consumption of a home. Having a Home energy label produced for each home constructed represents a marketing opportunity for industry to differentiate themselves as builders of high efficiency homes. The home energy label validates the builder’s investments in energy efficient construction and provides the consumer with the information to make an informed choice when purchasing a home.

Blower Door Test

What is a Mid-Construction Blower Door Test?

A mid-construction blower door test is a diagnostic test which depressurizes or pressurizes the home to identify unintentional leaks and issues with the air barrier. Importantly, the mid-construction blower door test needs to be scheduled at a point in the construction when it is not too late to effectively remedy identified air leakage issues.

A mid-construction blower door test service may include the following:

  • Measurements required for volume and area calculations;
  • Performing the airtightness test using a blower door fan;
  • Locating and documenting the air leakages – while the home is depressurized or pressurized you can walk around the home and feel air being drawn into the house through unintentional gaps in the building envelope;
  • Determining preliminary blower door metrics using HOT2000 or other software;
  • Air changes per hour (ACH) and/or;
  • Normalized leakage area (NLA) and/or,
  • Normalized leakage rate (NLR)

The mid-construction blower door test service can also include:

  • Blower door guided air sealing (where the energy advisor is on site with the blower door while a crew is conducting air sealing. This allows the builder to benefit from the expertise of the energy advisor and the confirmation that the air leakage target is achieved);
  • Providing a formal mid-construction blower door test report (with narrative and images of air leakage areas);
  • Other tasks agreed to between the two parties (e.g. repeated test to check for improvement).

Benefits of a mid-construction blower door test include:

  • A mid-construction blower door test helps your company avoid surprises and helps you to meet energy efficiency targets early in the process.
  • A home built with minimal levels of air leakage (and right ventilation) can reduce heat loss and energy bills in the winter, keep the home cooler in the summer, improve home comfort, enhance air quality, protect the building structure and other materials from moisture damage, and help prevent dust, noise, and insects from entering from outdoors.
  • A well-built and air sealed home can also shrink the environmental footprint of the home by reducing the greenhouse gas emissions produced by using energy to heat and cool your home.
  • The cost of addressing air leakage issues at the right time in the construction process can be negligible. If you wait until construction has been completed to identify air leakage issues, fixing the problem may be time consuming, expensive, or nearly impossible.
  • The mid-construction blower door test can be a practical teaching tool for your crews and sub trades. Involve them in the process: the test can be an opportunity for them to learn how to identify and address air leakage issues many builders have called the mid-construction blower door test more educational than weekend-long workshops on air tightness.

Contact your energy advisor’s service organization. The service organization is responsible for training energy advisors, providing supervision and technical support and monitoring that established Natural Resources Canada procedures are followed.

Energy Efficient Buildings

How are Passive house’s more energy efficient and climate-friendly then typical homes?

Passive houses aim to achieve the highest level of energy efficiency and climate-consciousness by designing the homes function and style based on its geographical location, solar orientation, and climatic region. With these aspects in mind, the house is modelled by a Passive House Institute Certified Professional using the Passive House Planning Package (PHPP) to ensure the building will meet the high performance requirements of the Passive House Standard. A Passive House is characterized by having very high insulation levels in all of its assemblies and achieving excellent airtightness, resulting in minimal heat loss through the building envelope. With consideration of the building’s geographical location and orientation, thoughtful placement of windows and overhangs allow Passive Houses to maximize passive solar gains. High-efficiency heating and cooling systems, as well as heat recovery ventilation (HRV) systems, are incorporated to further reduce the amount of energy needed to heat and cool the home. The combination of high R-Value assemblies, passive solar design, and efficient HVAC systems, mean that Passive Houses use very little energy, and thus have very low emissions. Passive Houses consume up to 90 percent less heating and cooling energy than conventional buildings. Renewable energy systems such as solar photovoltaic (solar panels) are often installed so that the building generates all of its energy needs. With all of these features, Passive Houses produce little to no greenhouse gas (GHG) emissions, making them sustainable and climate-friendly.

How do I get my home Passive Certified?

A Passive House Certification is internationally recognized as the highest level of building efficiency through all stages of design, construction and livability. Within the BC Building Code, homeowners can voluntarily adopt the Passive House Standard to achieve and exceed the highest step levels of the BC Energy Step Code.

To start the certification process you will need to engage a Passive Certifier approved by the Passive House Institute, ideally at the beginning of a new construction project. To find a Passive House Professional or learn more about where to get started, contact Passive House Canada.

What is a Passive House?

Passive Certified Buildings are residential, commercial and/or industrial buildings that have voluntarily adopted a building design and development that incorporates and implements the highest level of building envelope energy efficiency, comfort and climate-consciousness. Passive House buildings consume up to 90 percent less heating and cooling energy than conventional buildings. Passive houses achieve these high levels of performance by requiring building envelope airtightness of 0.6 air changes per hour (ACH @50Pa) or less, and utilizing renewable energy technologies (ie. Solar Photovoltaic, solar domestic hot water systems, etc.).

What are the benefits of building an energy efficient home?

Buildings built to higher energy-efficiency standards provide multiple benefits to those who live within them and to the community-at-large. A home built with high insulation levels, air-tight construction, high-quality windows, and more efficient mechanical systems are often preferred as they:

  • Improve comfort, by better managing temperature: high insulation levels and air-tight construction and appropriate ventilation controls the air from entering or exiting the home, maintaining warm temperatures in the winter, and cool temperatures in the summer.
  • Improve health, by better managing fresh air throughout the building: building a new home with an HRV provides ample fresh air even when the windows are closed, filtering and pre-warming incoming air for better health and exchanging heat to save energy.
  • Reduce noise: high levels of insulation, air-tightness, and high-efficiency windows can reduce unwanted outdoor noise. This is especially beneficial for homes built in busy or noisy areas or for individuals who enjoy peace and quiet.
  • Require less energy: high-efficiency heating equipment, paired with an efficient building envelope, requires less energy to heat and cool a home, which reduces the ongoing monthly and annual operating costs of the home.
  • Have lower greenhouse gas emissions: buildings are a significant source of energy consumption and greenhouse gas emissions in Canada. Building a home to high energy efficiency standards reduces the amount of greenhouse gasses in the atmosphere and reduces your personal household environmental footprint.
  • Are more durable: energy efficient homes are constructed with an enhanced focus on the building envelope with better design and construction practices, which generally enhances the quality of the home.

For more information see BC Housing’s guide Consumer Guide to High Performance Homes.

BC Energy Step Code

What is the BC Energy Step Code?

The BC Energy Step Code is an optional compliance path in the BC Building Code that local governments can voluntarily adopt and use to incentivize or require higher levels of energy efficiency in new construction development. The BC Energy Step Code was introduced as a step-by-step building efficiency strategy designed to help meet the Provincial Government’s target of all new homes being net-zero energy ready by 2032.

For Part 9 homes and buildings, the BC Energy Step code sets five performance levels or “steps” that exceed the base BC Building Code, with the higher steps being more energy efficient. Step 1 indicates a home performs as well as, or better, than a building constructed to meet the minimum prescriptive energy efficiency requirements of the BC Building Code. Step 5 indicates the home has been constructed as net-zero energy ready (NZER), meaning it produces as much energy as it consumes. Local governments can choose to require or incentivize a given step for new home construction in their community. Builders and developers have an opportunity to set themselves apart by building to higher steps than required.

While the BC Energy Step Code is currently adopted by municipalities on a voluntary basis, in future years the Province of BC may require that certain steps must be met in order to meet Provincial targets. By adopting the BC Energy Step code, local governments and their communities will be able to take advantage of the multiple benefits associated with more energy efficient new homes, including:

  • Greenhouse Gas Reductions – High-efficiency homes require less energy to heat, resulting in reduced carbon emissions even if homes heat with fossil fuels. Homes heated with a heat pump will have the lowest carbon emissions.
  • Better Affordability – Reduced energy consumption results in lower energy costs.
  • Increased Comfort – Increased insulation and airtightness within a home means that it is better equipped to maintain a more even temperature throughout, for a more comfortable home.
  • Better Health – Energy efficient homes do a better job of refreshing the indoor air by filtering out unwanted mould, moisture, pollen and other allergens.
  • Improved Durability – A high-efficiency home is less likely to have moisture and condensation issues that can lead to the deterioration of the building envelope.

If you are interested in learning about the Step Code or planning to build to Step Code level 1, 2, 3, 4 or 5, you can find more information at the official website, BC Energy Step Code, or speak with an Energy Coach to find out where to get started or contact an Energy Advisor to start planning your BC Energy Step Code compliant new construction.

How does the BC Energy Step Code compare to other green building labeling and certification programs: PassiveHouse, BUILTGREEN®, ENERGY STAR®, R2000, LEED

Throughout British Columbia there are various green building labeling and certification programs available. In the past, many municipalities had adopted a particular building certification as a mandatory requirement for builders to obtain a building permit, such as:
BUILTGREEN®
 ENERGYSTAR®
R2000
LEED
PassiveHouse

The building and administrative requirements for each green building program vary and not all builders have knowledge about every certification program. This can become complicated and costly to builders when bordering municipalities adopt different green building certification programs. The BC Energy Step Code is a uniform building energy performance standard which allows builders to build in multiple jurisdictions without worrying about different labeling or certification standards.

The BC Energy Step Code is not designed to replace green building program certifications, but rather to provide a consistent energy metric baseline for performance modelling across all municipalities.

The BC Energy Step Code also reduces the need for builders to complete added administrative requirements that are mandatory for many programs listed above. While there is still a cost to work with an energy advisor to obtain an EnerGuide evaluation, the BC Energy Step Code will reduce the administrative workload that many builders need to meet in order to achieve green building certifications.

What can I do if there are no new homes energy advisors currently servicing my location?

A majority of the work involved in delivering an EnerGuide evaluation for new home construction can be completed remotely. If there are no energy advisors located in the area you are building the home, try to connect with an Energy Advisor nearest to your city/town and ask if they’re willing to visit your location to conduct a final site visit after the construction of your home.
