Understanding Sustainable Certification in Construction
What is Sustainable Certification?
Sustainable certification in construction refers to a formal recognition awarded to buildings or construction practices that meet specific environmental standards. These certifications are aimed at promoting environmentally responsible and resource-efficient building methods.
Types of Sustainable Certifications
- LEED (Leadership in Energy and Environmental Design): Perhaps the most well-known, LEED certification focuses on a wide range of areas, including energy efficiency, indoor environmental quality, and sustainable site development.
- BREEAM (Building Research Establishment Environmental Assessment Method): Originating in the UK, this certification assesses the environmental performance of buildings throughout the design, construction, and operation stages.
- WELL Building Standard: This certification focuses more on human health and well-being, covering air, water, nourishment, light, fitness, and comfort.
- Green Globes: A flexible and interactive certification that allows for customizable sustainability goals, primarily used in North America.
Key Criteria for Certification
Energy Efficiency
Energy efficiency is a cornerstone of most sustainable certification programs. This includes reducing energy consumption through high-efficiency HVAC systems, lighting, and windows.
Water Conservation
Water conservation is another important criterion. Certified buildings often integrate low-flow plumbing fixtures, rainwater harvesting systems, and efficient irrigation techniques.
Materials and Resources
To achieve sustainable certification, buildings must use materials that are sustainable, recycled, or have a low environmental impact.
Indoor Environmental Quality
Considerations include air quality, natural lighting, and the use of non-toxic paints and finishes.
Benefits of Sustainable Certification
| Benefit | Description |
|---|---|
| Reduced Operating Costs | Energy and water efficiency measures can significantly lower utility bills. |
| Enhanced Marketability | Certified buildings are often more attractive to tenants or buyers who value sustainability. |
| Improved Health and Well-being | Better indoor environmental quality can lead to healthier, more productive occupants. |

Exploring Beyond the Basics of Building Certification
Regional and Specialized Certifications
In addition to global certifications like LEED and BREEAM, there are various regional and specialized certifications addressing specific local concerns and building types. For example:
- CASBEE (Comprehensive Assessment System for Built Environment Efficiency): A system developed in Japan that evaluates buildings considering both environmental load reduction and quality of indoor environment.
- Living Building Challenge: This certification focuses on creating buildings that operate as cleanly, efficiently, and beautifully as a flower. It demands rigorous standards and net-positive impact on the environment.
- Green Star: An Australian rating system that evaluates projects based on their environmental impact across multiple categories, including site selection, water, energy, and indoor environment quality.
Emerging Trends in Certification
The world of sustainable certification is continually evolving to adapt to new environmental challenges and technological advancements. Some emerging trends include:
- Net-Zero Energy Buildings: Projects that generate as much energy as they consume through renewable energy sources are increasingly favored and recognized by certification bodies.
- Adaptation to Climate Change: Certifications are evolving to consider projects’ resilience to climate-related impacts, such as extreme weather events and rising sea levels.
- Health-focused Standards: Beyond WELL, new certifications are emerging that prioritize mental well-being, such as Fitwel, which assesses building impacts on occupants’ mental and physical health.
Financial Incentives and Support
Many governments and financial institutions offer incentives to encourage sustainable building practices:
- Tax Credits and Rebates: Various tax incentives can offset the higher upfront costs of constructing sustainable buildings.
- Green Building Loans: Some banks offer loans with favorable terms for projects pursuing green certifications.
- Subsidies and Grants: Government grants and subsidies can significantly reduce the financial burden of sustainable building construction.
Local Government Initiatives
Local governments around the world are implementing policies to encourage sustainable construction. These initiatives include expedited permitting processes for green buildings, mandatory green building codes, and public awareness campaigns.
For example, some cities have adopted “Green Building Ordinances” requiring new constructions to meet specific sustainability criteria.
How Does Masonry Contribute to Sustainable Building Certifications?
Thermal Mass and Energy Efficiency
Masonry materials such as brick, stone, and concrete have high thermal mass. This means they can absorb heat during the day and release it at night, reducing the need for heating and cooling systems. By regulating indoor temperatures naturally, masonry helps buildings achieve energy efficiency—a key criterion for most sustainable building certifications like LEED and BREEAM.
Durability and Longevity
Masonry buildings are known for their long lifespan and durability. The longevity of these structures means they require less frequent renovations and rebuilds, reducing material use over time. This contributes to sustainability by minimizing waste and the environmental impact of resource extraction and processing, which is favorable under various certification systems.
Local Material Sourcing
Many masonry materials can be sourced locally, especially stone and brick. Using local materials reduces transportation emissions and supports the local economy. Certifications such as LEED reward projects for using locally-sourced materials, as it helps lower the building’s overall carbon footprint.
Low Maintenance and Aesthetics
Masonry requires minimal maintenance compared to other materials. For example, concrete and brick facades often need less frequent painting and repairs, reducing the use of chemicals and resources over time. Additionally, masonry’s aesthetic qualities can eliminate the need for additional cladding or finishes, reducing material consumption further.
Recyclability and Waste Management
Masonry materials are often recyclable. For instance, concrete can be crushed and reused as aggregate, while bricks can be reclaimed and used in new projects. Effective waste management and recycling are vital components of sustainability certification criteria. Projects that demonstrate effective recycling practices gain additional points.
Fire Resistance
Masonry buildings generally offer excellent fire resistance, which contributes to occupant safety and building longevity. This aspect indirectly supports sustainability by ensuring that structures remain safe and operational for longer periods, reducing the need for new construction and associated resource use.
Contribution to Water Efficiency
Modular masonry materials like bricks can be designed to support water-efficient landscaping solutions, such as permeable paving. This aids in groundwater recharge and reduces runoff, aligning with certification goals focusing on water conservation.
Acoustic Performance
Masonry materials provide excellent acoustic insulation, contributing to indoor environmental quality by reducing noise pollution. This supports certification requirements related to creating healthier and more pleasant living and working environments.
