LEED Certification
LEED Rating Systems
The LEED (Leadership in Energy and Environmental Design) rating system offers a range of certifications tailored to specific project types. For Building Design and Construction, LEED BD+C covers new construction and major renovations, addressing the complete design and construction process. LEED ID+C, focusing on Interior Design and Construction, assesses the sustainability of interior spaces, considering factors like material selection, indoor environmental quality, and energy efficiency. LEED O+M (Building Operations and Maintenance) evaluates the ongoing performance of existing buildings, emphasizing energy efficiency, water conservation, and green cleaning practices. LEED ND (Neighborhood Development) takes a holistic approach to community planning, assessing factors like walkability, mixed-use development, and green infrastructure. LEED Homes certifies single-family homes, low-rise multi-family buildings, and mid-rise multi-family buildings, focusing on energy and water efficiency, indoor air quality, and sustainable materials. By offering specialized rating systems, LEED ensures that projects of all types can strive for the highest standards of sustainability and environmental performance.
LEED Certification Process
The LEED certification process begins with registering the project on the USGBC website. The project team then collects documentation demonstrating compliance with LEED prerequisites and credits. This includes submitting plans, calculations, and other evidence of sustainable design strategies. The submitted materials are reviewed by the USGBC for completeness and accuracy. If additional information is needed, the project team is notified and given an opportunity to provide clarifications or revisions. Once the review is complete, the USGBC determines the level of certification achieved based on the number of points earned. The project team receives a final certification report detailing the credits achieved and any feedback for improvement. Successful projects are awarded a LEED certification plaque and listed in the USGBC’s public directory of certified projects. The entire process typically takes several months from registration to final certification, depending on the project’s complexity and the team’s responsiveness to USGBC inquiries.
BREEAM Certification
BREEAM Categories
BREEAM assesses buildings across ten key sustainability categories. Energy evaluates energy efficiency, renewable sources, and CO2 emissions. Health & Wellbeing focuses on indoor air quality, thermal comfort, and natural light. Innovation recognizes exemplary performance and innovative solutions. Land Use assesses site ecology and biodiversity protection. Materials examines responsible sourcing, embodied impact, and durability. Management covers project management, commissioning, and stakeholder engagement. Pollution addresses air, water, light, and noise pollution. Transport looks at accessibility, alternative transport, and travel plans. Waste evaluates construction waste management and operational waste. Finally, Water assesses water consumption, efficiency, leakage detection, and reuse. By comprehensively addressing these categories, BREEAM provides a holistic approach to evaluating and certifying the sustainability performance of buildings and infrastructure projects.
BREEAM Certification Levels
BREEAM offers five certification levels based on the project’s score: Pass (30-44%), Good (45-54%), Very Good (55-69%), Excellent (70-84%), and Outstanding (≥85%). The Pass level demonstrates that the project meets BREEAM’s minimum standards for sustainability, while higher levels showcase increasing commitment to environmental performance. Projects aiming for Excellent or Outstanding ratings must implement innovative strategies and achieve exemplary performance in multiple categories. The score thresholds ensure that certified projects meet rigorous sustainability criteria, with higher levels setting the bar for industry best practices in green building design and construction.
Green Globes Certification
Green Globes Assessment Areas
The Green Globes assessment covers seven key areas for sustainable building practices. Project Management evaluates the integration of environmental strategies, goal setting, and team collaboration. Site assessment focuses on sustainable site planning, ecosystem protection, and stormwater management. Energy efficiency is a critical area, examining energy performance, renewable energy use, and commissioning. Water conservation measures, such as efficient fixtures and landscaping, are evaluated in the Water category. The Resources section assesses materials selection, waste management, and building reuse strategies. Emissions covers indoor and outdoor air quality, pollution prevention, and low-emitting materials. Finally, the Indoor Environment category examines factors like thermal comfort, daylighting, acoustics, and occupant well-being. Green Globes provides a comprehensive framework for assessing and improving the sustainability of building projects across these essential areas, promoting environmentally responsible design and construction practices.
Green Globes Certification Process
The Green Globes certification process begins with an online questionnaire that assesses a building’s sustainability across various categories, including energy, water, materials, and indoor environment. The questionnaire is designed to be user-friendly and allows project teams to input data and receive immediate feedback on their performance. Once the questionnaire is complete, a third-party assessor conducts an on-site evaluation to verify the information provided and gather additional data. The assessor then submits a report to the Green Building Initiative (GBI), which reviews the findings and assigns a rating based on the building’s overall sustainability. Green Globes ratings range from one to four globes, with four globes representing the highest level of achievement. The certification process is known for its flexibility and emphasis on continuous improvement, making it an attractive option for projects of various sizes and types.
Living Building Challenge
Living Building Challenge Petals
The Living Building Challenge, a rigorous green building certification, is based on seven performance categories called ‘Petals.’ The Place Petal focuses on the building’s relationship with its ecological context, encouraging the use of native plants and habitat restoration. Water and Energy Petals aim for net-positive water and energy, requiring on-site generation and efficient use. Health & Happiness promotes occupant well-being through healthy interiors and biophilic design. The Materials Petal advocates for non-toxic, ecologically responsible, and transparent materials. Equity ensures accessibility and inclusion for all, while Beauty celebrates the project’s aesthetic value and inspiration. Together, these Petals create a holistic approach to sustainable design, pushing projects to have a positive impact on both the environment and occupants.
Living Building Challenge Certification Types
The Living Building Challenge offers three certification types based on the level of achievement. Living Building Certification is the most rigorous, requiring projects to meet all seven performance categories, or “Petals,” which include Place, Water, Energy, Health & Happiness, Materials, Equity, and Beauty. Petal Certification recognizes projects that achieve at least three of the seven Petals, with Energy, Water, and one other Petal being mandatory. This allows for incremental progress towards full Living Building Certification. Lastly, Zero Energy Certification is awarded to projects that generate 100% of their energy needs on-site through renewable sources, without combustion, and meet certain requirements related to efficiency, resilience, and information sharing. These certification types provide flexibility for projects at different stages of their sustainability journey while encouraging continuous improvement and innovation in the built environment.
