BREEAM New Construction (NC) Residential is a sustainability assessment framework designed to evaluate and enhance the environmental performance of new residential buildings during their design and construction phases. It provides guidance and benchmarks to ensure that homes are built to reduce environmental impacts, improve occupant well-being, and deliver economic and social benefits.
Structure of BREEAM NC Residential
The BREEAM NC Residential framework assesses the sustainability of new residential developments across several key categories. Each category includes specific criteria that contribute to the building’s overall sustainability rating:
- Management:
- Focuses on effective project management, stakeholder communication, and quality assurance throughout the design and construction phases.
- Encourages practices like life-cycle costing and post-occupancy evaluation.
- Health and Well-being:
- Evaluates features that promote comfort and well-being for residents, such as natural light, acoustic performance, thermal comfort, and indoor air quality.
- Energy:
- Assesses energy consumption, efficiency, and emissions.
- Encourages the use of renewable energy systems, smart metering, and highly efficient heating and cooling solutions.
- Transport:
- Promotes sustainable transport options by assessing proximity to public transport, pedestrian-friendly design, and facilities for bicycles or electric vehicles.
- Water:
- Focuses on reducing water consumption through efficient fixtures, leak detection systems, and rainwater harvesting.
- Materials:
- Evaluates the environmental impact of building materials.
- Encourages the use of responsibly sourced, low-impact, and durable materials.
- Waste:
- Addresses waste management during construction and occupancy.
- Promotes practices such as recycling, reuse, and the reduction of construction waste.
- Land Use and Ecology:
- Considers the development’s impact on the local environment.
- Encourages biodiversity protection, enhancement of green spaces, and sensitive site selection.
- Pollution:
- Assesses measures to reduce air, water, and soil pollution.
- Includes criteria for managing stormwater runoff, minimizing light pollution, and reducing noise.
- Innovation (optional):
- Rewards exceptional practices and innovative solutions that go beyond standard sustainability benchmarks.
Assessment Process
- Registration:
- The project is registered with a licensed BREEAM certification body early in the planning stage.
- Pre-Assessment:
- A preliminary review is conducted to identify sustainability goals and establish a pathway for achieving BREEAM credits.
- Design Stage Assessment:
- During the design phase, the plans and specifications are reviewed by a BREEAM assessor to ensure compliance with the framework.
- Post-Construction Assessment:
- After construction is complete, the building is evaluated to confirm that all planned sustainability measures have been implemented.
- Certification:
- The residential project is awarded a BREEAM rating, from Pass to Outstanding, based on the credits achieved.
Rating and Scoring
The overall score is calculated based on credits earned in each category, weighted by their environmental significance. The final ratings include:
- Outstanding (≥ 85%)
- Excellent (≥ 70%)
- Very Good (≥ 55%)
- Good (≥ 45%)
- Pass (≥ 30%)
