GREEN STAR

In an era where sustainability and environmental responsibility are paramount, Green Star certifications have become essential benchmarks for builders and developers aiming to create sustainable and high-performing buildings in New Zealand.

Navigating the certification process and ensuring compliance with the rigorous criteria can be a challenging endeavor. This is where Siecap (NZ) comes into the picture as your trusted partner and expert advisor.

What is Greenstar?

Green Star NZ rating system consists of a comprehensive set of credits across different categories, each representing a different aspect of sustainability. These categories may include energy, water, materials, indoor environment quality, transport, and innovation. Buildings earn points for meeting specific criteria within each category, and the total number of points determines the level of certification achieved. The Green Building Council of New Zealand (NZGBC) oversees the Green Star certification process, and the system has been widely embraced by the construction industry.

Green Star NZ provides different levels of certification: 4 Green Star, 5 Green Star, and 6 Green Star. These levels represent progressively higher levels of sustainability performance, with 6 Green Star being the highest level achievable and 4 Star being a min requirement in New Zealand.
