The Impact of LEED Certification on Canadian Construction & How to Be Aligned
LEED certification is widely recognized as a benchmark for excellence in sustainable building. It represents a commitment to environmental stewardship and marks a critical step in the industry's move towards green building practices. Here, we outline how to align large construction projects with LEED guidelines to promote better building processes across Canada.
What is LEED?
Leadership in Energy and Environmental Design (LEED) certification is a globally recognized symbol of sustainability achievement and leadership. It provides a framework for healthy, highly efficient, and cost-saving green buildings. LEED is crucial in promoting sustainable design and construction, influencing everything from initial planning and design to long-term maintenance and operations.
How to Achieve LEED Certification for Large-Scale Construction Projects
For Large scale construction projects, adhering to LEED certification standards involves strategic planning and advanced technical integration from the ground up. These projects require a holistically sustainable approach to resource management, energy modelling, and environmental impact assessments.
1. Manage with Integrated Project Delivery (IPD)
Large projects benefit immensely from IPD, an approach that integrates people, systems, business structures, and practices into a collaborative process that focuses on the talents and insights of all participants. This method has been shown to increase value, reduce waste, and maximize efficiency through all phases of design, fabrication, and construction.
2. Advanced Energy Modeling
This step is crucial for large buildings, as it predicts energy usage and performance. Using digital tools and software, construction managers can simulate energy consumption and optimize the building's architectural and mechanical systems to reduce energy loads and enhance overall energy efficiency.
3. Source the Right Materials
Large projects require massive quantities of materials. Utilizing materials with high recycled content and regional materials can minimize environmental impact. For instance, sourcing aggregate locally reduces transportation-related carbon emissions, supporting LEED's MR (Materials and Resources) credits.
4. Integrate Water Efficiency Technologies
For large constructions, implementing high-efficiency plumbing fixtures, water recycling systems, and stormwater management solutions is essential. Techniques like greywater reuse and rainwater harvesting can significantly reduce the demand for potable water and manage runoff in urban settings.
5. Manage Construction Demolition Material (CDM) Effectively
Developing a CDM plan is necessary for any sustainability-focused project. This includes strategies for recycling, reusing, and diverting materials from landfills. On large projects, detailed planning can ensure that materials are managed sustainably throughout the construction phase.
Materials That Make a Difference
A significant aspect of achieving LEED certification involves using sustainable materials with a low carbon footprint. Among these, low-carbon cement and concrete are central. Traditional cement production is highly energy-intensive and contributes to significant CO2 emissions. In contrast, green cement products offer a lower-carbon alternative, made from recycled materials and designed to reduce the environmental impact of the buildings.
Other materials that contribute to LEED points include:
- Recycled Steel: Utilizing recycled steel reduces the need for new raw materials, significantly lowering the carbon footprint associated with construction.
- Low-Emission Glass and Paints: These materials help reduce toxins in the environment and enhance indoor air quality—a critical component of LEED's sustainable building criteria.
- High-Performance Fly Ash Concrete: Employing fly ash as a partial replacement for Portland cement in concrete significantly reduces the carbon footprint of construction materials. This byproduct of coal combustion enhances the durability and strength of concrete.
Benefits of LEED Certification
Pursuing LEED certification can elevate a project's marketability and operational efficiency. Buildings with LEED certification typically consume less energy and water, produce lower greenhouse gas emissions, and provide healthier indoor environments. Additionally, they tend to have increased asset value compared to non-certified buildings.
The Business Impact
For businesses engaged in large-scale projects, LEED certification serves as a framework for improving efficiency and reducing long-term costs. Most importantly, it signifies a commitment to environmental stewardship and positions a company as a leader in sustainable practices. This appeals to clients who are increasingly prioritizing green credentials.
As more governments and clients demand sustainable buildings, having LEED-certified projects can significantly enhance a company's competitiveness in the market.
