At 22 Degrees, we believe smart design is sustainable design. Environmentally friendly, cost-effective solutions are not just good for the planet, they’re good for long-term building performance and value.
Our sustainability team supports clients with expert advice and analysis from the earliest stages of a project. We use a range of specialist tools to guide decisions, including due diligence and energy audits, NABERSNZ & Green Star assessments, condition assessment Reports, daylight modelling, H1 energy analysis reports and whole of life embodied carbon assessments.
Kaitiakitanga is central to our “why”. It is at the heart of our focus on sustainability. The concept of guardianship of sky, sea, and land to preserve the environment for future generations is incorporated into everything we do. As a founding member of the New Zealand Green Building Council (NZGBC), we’re committed to creating buildings that are healthier, more efficient, and future ready. We help clients reduce consumption and maximise passive sources of light, air, water, and energy. This saves money, reduces waste, and helps our clients show their commitment to sustainability.
Our sustainability services include:
NABERSNZ
A high NABERNZ rating means lower operating costs and a more attractive space for potential tenants. As a leading NZ rating system, NABERSNZ measures and evaluates the environmental performance of an office. A NABERSNZ rating benchmarks an office’s energy efficiency and identifies opportunities to improve performance.
Our fully certified team offers the full suite of NABERSNZ services, from initial survey and advice, to reporting and certifying a building with NZGBC. We go beyond the basics of assessment and certification and provide a roadmap of possible energy saving measures, enhancing the rating further.
Homestar
Homestar is fast becoming the gold standard for the residential building industry. Homestar-rated homes are more comfortable and more efficient, making them desirable to homebuyers and tenants.
Our skilled team of certified Homestar Designers and Assessors are accredited with the NZGBC. They work closely with design teams on developments, advising on Homestar requirements and guiding the design process. They can also manage the application to NZGBC and provide both design and built Homestar ratings for homes.
Green Star
Green Star, administered by NZGBC, is the leading sustainability rating for non-residential buildings in New Zealand. It assesses energy use, water efficiency, waste management, and the use of responsibly sourced materials.
Whether planning a new build or renovation, Green Star helps ensure your project is environmentally responsible, energy-efficient, and healthy for occupants. While it may increase upfront costs, it delivers long-term savings and appeals to tenants and investors seeking sustainable outcomes.
Our sustainability team includes NZGBC accredited Green Star professionals who guide clients from concept to completion – achieving both Design and As-Built ratings.
Embodied Carbon Whole of Life Assessment Reports
Embodied carbon accounts for all greenhouse gas emissions associated with a building’s materials from extraction and manufacturing, through transport and construction, to maintenance, reuse, and end-of-life disposal.
Unlike operational carbon, which relates to the energy used during a building’s life, embodied carbon is locked in from day one. Operational emissions are assessed through tools like NABERSNZ and Green Star, while embodied carbon requires a different lens.
Our expert carbon assessors guide clients in selecting low-carbon, responsibly sourced materials. We use a suite of industry-leading tools and benchmarks to deliver accurate, actionable assessments that support sustainable design decisions.
