Understanding the BC Energy Step Code and Its Impacts on the Construction Industry.
The BC Energy Step Code is a policy framework introduced by the province of British Columbia in April 2017. Its primary aim is to create more energy-efficient buildings, reduce greenhouse gas emissions, and encourage the construction industry to adopt sustainable practices.
Unlike traditional building codes, which focus on prescriptive measures, the BC Energy Step Code sets clear performance-based targets, requiring builders to meet specific energy efficiency standards. By 2032, the province aims to ensure all new buildings are net-zero energy-ready, meaning they are highly energy-efficient and capable of meeting their energy needs with renewable sources.
What is the BC Energy Step Code?
The BC Energy Step Code is a voluntary compliance path within the BC Building Code that local governments can adopt to enforce more stringent energy efficiency standards in their jurisdictions. It provides a progressive framework with multiple “steps,” each representing a higher level of energy performance:
- Steps 1 and 2: Incremental improvements over the standard BC Building Code, allowing builders to familiarize themselves with performance-based requirements.
- Steps 3 to 5: Advanced levels of efficiency leading to net-zero energy-ready buildings, which produce as much energy as they consume.
The Step Code applies to both residential and commercial buildings and uses metrics such as energy use intensity (EUI), airtightness, and mechanical system efficiency to evaluate performance.
What Problems Does the Step Code Address?
The BC Energy Step Code addresses several critical issues related to energy consumption, climate change, and building performance:
- Reducing Greenhouse Gas Emissions: Buildings are significant contributors to greenhouse gas emissions, accounting for approximately 18% of Canada’s emissions, primarily due to heating and cooling systems. The BC Energy Step Code aims to tackle this issue by promoting energy-efficient designs that require less energy to operate.
- Improving Building Performance: Traditional building codes often prescribe specific construction techniques or materials without focusing on overall building performance. The BC Energy Step Code shifts this approach, requiring builders to meet performance-based targets. This ensures buildings are well-insulated, airtight, and equipped with efficient mechanical systems, resulting in better occupant comfort and lower operational costs.
- Standardizing Energy Efficiency: Prior to the BC Energy Step Code, municipalities in BC had varying requirements for energy efficiency, leading to inconsistencies. The Step Code creates a unified framework, providing clarity for builders and fostering a level playing field across the province.
- Encouraging Long-Term Sustainability: By setting clear timelines and goals, the Step Code encourages the construction industry to adopt sustainable practices gradually, minimizing disruption while maximizing environmental benefits.
“The BC Energy Step Code is a transformative policy that sets a clear path toward sustainability, fostering innovation and reducing emissions.” Brad Hedblom – President.
Similar Initiatives in the US.
The United States and Europe have implemented similar initiatives to the BC Energy Step Code, reflecting their commitment to advancing energy efficiency and sustainability in construction.
In the United States, the Zero Energy Ready Home (ZERH) program, overseen by the U.S. Department of Energy, certifies homes that adhere to stringent energy efficiency standards and are equipped for renewable energy integration. This program ensures that residential buildings not only meet today’s energy needs but are also future-proof for renewable technologies. Similarly, the Energy Star for Homes initiative sets rigorous energy performance benchmarks, certifying homes that achieve at least 10% greater efficiency compared to those built under conventional building codes. Both programs have made significant strides in reducing energy consumption and enhancing the overall efficiency of residential construction.
-
Impacts in the US: Programs like ZERH and Energy Star have led to measurable improvements in energy efficiency and reduced utility costs for homeowners. Builders have reported increased demand for high-performance homes, though initial costs remain a barrier for widespread adoption.
Similar Initiatives in Europe.
In Europe, the European Union Energy Performance of Buildings Directive (EPBD) mandates that all new buildings within EU member states meet nearly zero-energy building (NZEB) standards as of 2020. This directive provides a comprehensive framework for energy performance and actively promotes the integration of renewable energy systems into building designs.
Additionally, Germany’s Passivhaus Standard has become a leading benchmark for sustainable construction across the continent. This standard emphasizes ultra-low energy consumption through superior insulation, airtightness, and advanced mechanical ventilation systems, setting a high bar for energy-efficient building design.
-
Impacts in Europe: The EU’s NZEB mandate and the Passivhaus standard have significantly advanced sustainable construction. However, challenges such as training the workforce and integrating renewable energy systems persist. Feedback from stakeholders indicates that long-term cost savings and improved building quality outweigh initial expenses.
“While the Step Code presents challenges, it also offers significant opportunities for businesses willing to embrace change.” Lee Zirk – Principle
Who Does the BC Energy Step Code Affect?
The BC Energy Step Code affects a wide range of stakeholders, including:
- Builders and Developers: They must adapt to new performance-based requirements, which may involve additional training and investments in advanced technologies.
- Municipalities: Local governments can choose to adopt the Step Code, tailoring energy efficiency standards to their community needs.
- Homeowners and Occupants: Residents benefit from lower energy bills and more comfortable living spaces but may face higher upfront costs for new homes.
- Mechanical Services Companies: Companies like True Mechanical, which specialise in HVACR and high-rise plumbing, are significantly impacted. These businesses must adapt their practices to meet new efficiency standards.
Positive Impacts of the BC Energy Step Code on the Construction Industry.
The BC Energy Step Code encourages the adoption of cutting-edge materials, designs, and technologies, fostering innovation within the sector and pushing industry boundaries. Additionally, it creates significant opportunities for growth as companies that adapt quickly can position themselves as leaders in sustainable construction, gaining a competitive edge in an evolving market.
Moreover, the improved energy efficiency promoted by the Step Code directly contributes to reducing carbon emissions, aligning with Canada’s broader climate goals and supporting global efforts to combat climate change.
- Increased demand for high-efficiency HVAC systems, heat pumps, and advanced plumbing solutions.
- Opportunities to develop expertise in energy modelling and system optimization.
Negative Impacts of the BC Energy Step Code on the Construction Industry.
The BC Energy Step Code presents some challenges for the construction industry, particularly in terms of cost and workforce preparedness. Meeting the performance-based targets often necessitates significant upfront investments in advanced materials, innovative technologies, and specialized training. Additionally, builders and tradespeople must undergo comprehensive training to fully understand and implement the Step Code requirements, which can be both time-consuming and expensive. These factors highlight the importance of planning and support to ensure a smooth transition to the new standards.
- Higher costs for training and certification to comply with new standards.
- Potential disruption to existing workflows and supply chains.
Conclusion.
The BC Energy Step Code is a forward-thinking initiative that addresses critical issues like climate change, building performance, and energy efficiency. While it poses challenges for the construction and mechanical services industries, it also creates opportunities for innovation and growth. By learning from similar initiatives in the US and Europe, BC can refine its approach and ensure a successful transition to sustainable building practices. As the industry adapts, collaboration between stakeholders, government incentives, and ongoing education will be key to achieving the Step Code’s ambitious goals.
