Environmental certification – how do façades and aluminium joinery support BREEAM/LEED?

Modern construction is increasingly guided by the principles of sustainable development. Investors, architects, and developers are turning to solutions that not only improve user comfort but also minimise the environmental impact of buildings. In this context, international green building certification systems – such as BREEAM and LEED – play a vital role, demonstrating a clear confirmation of the project’s environmental quality. How do façades and aluminium joinery contribute to these requirements? Let’s take a closer look.

What are the BREEAM and LEED systems?

BREEAM (Building Research Establishment Environmental Assessment Method) and LEED (Leadership in Energy and Environmental Design) are the two most widely used building environmental performance assessment systems in the world. Although they differ in methodology, both systems focus on such areas as:

  • energy efficiency,
  • water management,
  • indoor environmental quality,
  • use of low-emission and recycled materials,
  • impact on the surrounding environment and local biodiversity.

The final assessment – confirmed by the relevant certificate – is a distinguished recognition and a valuable asset from an investment perspective.

Aluminium joinery and BREEAM/LEED certification requirements

Modern façades and aluminium windows and doors, such as those offered by Aluprof, actually support compliance with the criteria set out by both certification systems. But how do they do this?

1. Energy efficiency and thermal insulation

The aluminium façades in the MB-TT50, MB-SR50N or MB-MT50 systems make it possible to design external partitions with excellent thermal insulation parameters – often exceeding the requirements of Polish standard WT2021. This reduces the building’s demand for heating and cooling, directly contributing to a higher score in the ‘Energy’ (LEED), and ‘Energy’ and ‘Health & Wellbeing’ (BREEAM) categories.

2. Daylight access and visual comfort

Slimline mullion-transom façades with large glazed surfaces allow greater levels of natural daylight into interior spaces. In LEED, this aspect is assessed under ‘Daylight & Views’, while BREEAM assesses it under ‘Visual Comfort’. Thoughtful daylighting enhances not only user comfort but also improves productivity and overall wellbeing.

3. Low Emissions and Environmental Product Declarations (EPDs)

Aluprof’s solutions are manufactured from aluminium with a high recycled content and produced largely using renewable energy. Notably, many of these solutions are accompanied by type III EPDs (Environmental Product Declarations) – which are recognised and rewarded in both LEED and BREEAM. These declarations enable investors to clearly demonstrate the low environmental impact of materials throughout the entire life cycle of a building.

4. Indoor Air Quality and User Health

With emission-free painting technology and the use of health-safe components, Aluprof’s aluminium joinery contributes positively to indoor air quality. In both certification systems, this factor is a crucial element of the assessment – particularly for educational, office, and healthcare spaces.

5. Durability, resilience, and recyclability

Aluminium is a durable, corrosion-resistant material that can be easily recycled. Both BREEAM and LEED place strong emphasis on circular economy and waste management, so solutions that extend a building’s life cycle and are recyclable are rated particularly highly.

Aluprof – partner in sustainable construction

Aluprof actively supports designers and investors in achieving environmental certification goals. The aluminium systems offered are developed in line with sustainable development principles, as reflected in numerous BREEAM- and LEED-certified investments across Poland and abroad.

Project examples:

  • Varso Tower (BREEAM),
  • Mennica Legacy Tower (BREEAM and LEED),
  • Skysawa (BREEAM),
  • Brama Miasta (LEED).

With the support of the technical department and access to documentation (e.g. EPD, FDS, CE declaration), Aluprof ensures the smooth delivery of projects that meet even the most stringent sustainable building standards.

The LEED and BREEAM certification systems offer more than just a prestige certificate – they also provide tangible value to the environment and future users of the building. Joinery and aluminium façades from Aluprof not only help meet the criteria of both systems but often exceed them, making each project more responsible, comfortable, and modern.
