What Are the Sustainability Benchmarks for New Construction Under UK Green Building Standards?

When it comes to the building and construction industry, there’s an increasing focus on sustainability and environmental responsibility. In the United Kingdom, there is a specific set of green building standards that builders, developers, and architects must adhere to. These standards encompass a variety of factors including energy efficiency, waste management, and the use of sustainable products. Understanding these benchmarks is crucial for any professional involved in the construction of new buildings.

Understanding Green Building Standards in the UK

Green building standards are a collection of criteria that buildings must meet to be considered environmentally friendly. These standards cover a range of areas, including design, construction, operation, and maintenance. The main aim is to reduce the environmental impact caused by buildings while enhancing their overall performance. In the UK, the two main certifications that set these standards are BREEAM (Building Research Establishment Environmental Assessment Method) and LEED (Leadership in Energy and Environmental Design).

BREEAM Certification

One of the most widely used green building certification systems in the UK is BREEAM. Established in 1990, BREEAM sets the benchmark for best practice in sustainable building design. It assesses the performance of buildings in a range of categories, including energy, water use, health and wellbeing, pollution, transportation, materials, waste, and ecology. The result is a rating ranging from Pass to Outstanding.

BREEAM certification is a robust tool for assessing the environmental performance of both new and existing buildings. A BREEAM assessment uses recognized measures of performance, which are set against established benchmarks, to evaluate a building’s specification, design, construction, and use. The measures used represent a broad range of categories and criteria, from energy to ecology.

LEED Certification

LEED, on the other hand, is an internationally recognized green building certification system, providing third-party verification that a building or community was designed and built using strategies aimed at improving performance in metrics such as energy savings, water efficiency, CO2 emissions reduction, improved indoor environmental quality, and stewardship of resources and sensitivity to their impacts.

LEED provides a framework for healthy, highly efficient, and cost-saving green buildings. LEED certification is a globally recognized symbol of sustainability achievement and leadership. The rating system is based on points, the more points a project earns, the higher its LEED rating, culminating in the highest, which is LEED Platinum.

Key Benchmarks of Green Building Standards

In both BREEAM and LEED certification systems, there are several key benchmarks that buildings must meet or exceed. These benchmarks are designed to ensure that buildings are as environmentally friendly and sustainable as possible.

Energy Efficiency

Energy efficiency is a critical benchmark in both BREEAM and LEED. Buildings are responsible for a significant amount of energy consumption, and as such, improving energy efficiency is a crucial step towards creating more sustainable buildings. This involves using energy-efficient appliances and systems, as well as incorporating innovative solutions such as renewable energy sources and high-performance insulation.

Waste Management

In the construction industry, waste can have a significant impact on the environment. Therefore, effective waste management is another key benchmark of green building standards. This includes reducing, reusing, and recycling waste produced during construction, as well as implementing strategies for managing waste once the building is occupied.

Use of Sustainable Products

The use of sustainable products is another important benchmark. This involves choosing materials that are sourced responsibly and have a low environmental impact. In addition, the use of products that contribute to the overall sustainability of the building, such as low VOC paints and sustainable flooring options, is also taken into account.

WELL – The New Benchmark for Health and Well-being in Buildings

In recent years, there has been a growing focus on the impact of buildings on health and well-being. As such, the WELL Building Standard has been introduced to complement green building standards like BREEAM and LEED.

WELL is a performance-based system for measuring, certifying, and monitoring features of the built environment that impact human health and well-being, through air, water, nourishment, light, fitness, comfort, and mind.

WELL is grounded in a body of evidence-based research that explores the connection between the buildings where we spend approximately 90 percent of our time, and the health and wellness impacts on us as occupants.

Carbon Reduction – A Vital Element of Green Building Standards

In the face of growing concerns about climate change, carbon reduction has become a central element of green building standards. Both BREEAM and LEED certifications encourage practices that reduce the carbon footprint of buildings. This includes energy-efficient design and operation, use of renewable energy, and selection of low-carbon materials.

Reducing a building’s carbon footprint is no longer just a nice-to-have, but a must-have. Not only does it contribute to global efforts to curb climate change, but it can also result in significant cost savings over the life of the building. This makes it a win-win for both the environment and the bottom line.

Incorporating Green Building Standards into the Design and Construction Process

The integration of green building standards into the design and construction process is not just a trend—it’s a necessity. As the awareness of climate change and its impacts grow, so does the demand for sustainable construction. When builders, architects, and developers adhere to these standards, they are not only contributing to the preservation of the environment but also creating buildings that are healthier and safer for occupants.

The first step in this process is to identify the sustainability goals of the project. This could include energy efficiency, reduction of carbon emissions, or the use of environmentally friendly materials. Once these goals are defined, they should inform every aspect of the design and construction process—from site selection and building orientation to material selection and waste management.

The third party certification systems like BREEAM and LEED provide comprehensive guidelines for achieving these sustainability goals. They offer robust frameworks for assessing the environmental performance of buildings, including aspects like energy performance, water usage, waste management, and indoor environmental quality. By following these frameworks, professionals involved in the building process can ensure that their projects meet or exceed the sustainability benchmarks set by these rating systems.

Both these certifications also emphasize a life cycle approach to building design and construction. This means considering not just the immediate impacts of the building process, but also the long-term implications of the building’s operation and maintenance. By considering the entire life cycle of a building, professionals can make choices that minimize environmental impact while maximizing performance and efficiency.

The Future of Green Building Standards

Looking to the future, it is clear that green building standards will continue to play a critical role in the building and construction industry. With the threat of climate change looming larger than ever, the need for sustainable construction practices is undeniable.

The Building Research Establishment (BRE) and building councils globally are continuously working on improving and refining the building certification systems like BREEAM and LEED. New regulations and standards are being introduced to further push the envelope of sustainable construction. For example, many are now looking at ways to incorporate circular economy principles into building design and construction—focusing not just on reducing waste but also on reusing and recycling materials throughout a building’s life cycle.

Moreover, the focus of building standards is also expanding beyond the physical aspects of the building to include the health and wellbeing of occupants. With the introduction of certifications like WELL, the built environment is now being designed with a view to enhancing the quality of life of its occupants.

In conclusion, the future of construction lies in sustainable, high-performance buildings. As the industry continues to evolve, so too will the standards that guide its practices. By adhering to these standards, builders, architects, and developers not only contribute to environmental conservation efforts but also create buildings that are healthier, safer, and more enjoyable for occupants. The key is to keep evolving and innovating, always with an eye towards sustainability and the wellbeing of both the planet and the people who call it home.
