Long term sustainability, as well as the cost saving benefits of lowering consumption and utilising efficient double glazing is practised by Thermawood on a daily basis.

Building Strong Partnerships

We are committed to working with our strategic partners and the communities we engage with to promote efficient and environmentally sustainable lifestyle choices. Communication, accountability and social responsibility between stakeholders is of paramount importance at Thermawood and can be seen in our continued efforts to provide as much information and advice where possible.

At all times our approach is sustainable, environmentally aware and proficient. We have recently started to develop a number of strategic partnerships with like-minded organisations who share our vision for providing sustainable and environmentally beneficial products and services. Our choice in suppliers for key components of our system reflects this

Above all, we endeavour to continually improve our system and business performance through on-going research and development.

Environmental Strategy

The four focus areas of our environmental strategy are:

  1. Product design – Eco innovation. This involves a constant search for materials and technology that ensures a competitive edge. Our retrofit system is made from 100% recyclable and reusable materials.
  2. Supply Chain Management. We recognise the vital role our suppliers play in the production process of our system. That is why we have chosen supply companies that share our views and goals.
  3. Product Stewardship. End of life management is important to Thermawood. We aim to manage our products to minimize waste and ensure economic and environmental significance.
  4. Stakeholder Communications. We strive to have clear and open communication flows within and outside of the organization.

Indoor air quality (IAQ) is something that can be subtle and quite often, go unnoticed. According to the Ministry for the Environment (2011), while most of the air in New Zealand and Australia is clean and healthy to breathe, there are some places where air pollution and the quality of air available affects our health and enjoyment of the environment. The World Health Organisation recommends that the optimal indoor temperature for good health should be between 18ºC and 21ºC for vulnerable groups such as young children. A desirable IAQ will ensure that is will not cause or aggravate illness in building occupants while also securing a suitable level of thermo-comfort.

In 2012, began a research project in partnership with Unitec Institute of Technology to improve the indoor air quality of a local school as well as to promote education about sustainable lifestyle choices. Thermawood would like to thank DVS Healthy Home Group for their support in the Puni school project.

We have installed our system in one classroom (classroom A) and we have another classroom (classroom B) which acts as a control measure. We are actively measuring and surveying the differences between classroom A and classroom B. Upon installation of the system, immediate changes in comfort and temperature were noticed by users (both teachers and students). The ability for students to breathe easier and perform better at mental tasks is affected by changes in temperature. A recent study in Canada found that absenteeism was reduced in schools by 20% as the relative humidity in the facilities was increased from 22% to 35% (Ministry of Education, retrieved December 2011).
