Come along to hear fresh thinking and inspiration from leading industry experts, alongside the latest news and views on building technologies and tools.
The drive to reducing energy consumption and the associated greenhouse gas emissions is now more essential than ever. New technologies are continuously being developed making low-cost alternatives increasingly efficient.
Tony Sanderson, Principal - Mechanical Engineer from Stephenson & Turner will discuss his work on the recently refurbished Hutt City Council building, which features, for the first time in NZ, a ground source heat pump which uses pipework within the building’s structural piles, known as thermal piles.
These are a low-cost highly-efficient heating and cooling system which reduces overall energy consumption. There are 60 thermal piles used which go around 15-20 metres below the ground, where the earth temperature is very stable at around 10°C.
Come along to learn more about how the system was designed and how you may be able to apply thermal pile technology to your next project. View his bio
Sara Wareing (McKee Fehl Constructors) and Brian Berg (BRANZ) will discuss their work on New Zealand’s first Green Star Whole Building Life Cycle Assessment Innovation Challenge
Building Life Cycle Assessment, or LCA, is a quantitative technique of calculating the potential environmental impact of a building’s material, energy, and water consumption, over its full life cycle e.g. 60+ years. One of the benefits of the approach is that in addition to greenhouse gases, LCA calculates other environmental impacts such as water pollution, and resource depletion. It is particularly useful when applied early and iteratively during building design, so that environmental consequences of design choices can be tested, understood and refined. For environmental impacts such as Global Warming, this is becoming increasingly important. New Zealand’s ratification of the Paris Agreement in 2015 means that our country is committed to a 30% reduction in the 2005-level of greenhouse gas emissions by 2030, with this decreasing to zero by 2050. This has a direct impact on the way we are designing and constructing building’s today, as those same building will still be functioning and will be required to operate in this low to zero carbon future.
This covers what building LCA is, the research BRANZ and industry partners have done to make LCA easier for industry and building designers, and finally a description of how LCA has been applied (by non-experts) on a Wellington commercial building.
Cr Iona Pannett, Wellington City Council, Portfolio Leader for Infrastructure and Sustainability
Wellington City Council’s Iona Pannett explores how Wellington, one of the world’s most environmentally sustainable cities, can move from failure to success in the building area. From being quake prone, dirty, expensive and cold, it is possible to move to a city with high quality and affordable buildings for the future.
Wellington born and academically trained in history, Iona has 20 years of experience advocating for environmentally and economically sustainable cities. She also has a decade of experience in local government leading portfolios in areas such as water infrastructure, waste minimisation, building resilience and heritage preservation.
Priorities in her work include assisting owners to strengthen earthquake prone buildings and other critical infrastructure, reducing the city’s ecological footprint and increasing access to housing for all Wellingtonians.

Green Star Performance can be used for all buildings including retail, industrial, educational, healthcare, public buildings and offices. And has been designed to be used across building portfolios too. If you have a building, Green Star Performance can help you.
The new rating tool takes into account several categories, including energy, water and materials.Green Star Performance will help building owners, operators and occupants to measure and monitor the efficiency and impacts of their buildings, and take practical action to improve.This will be a short introduction to the tool leading up to the official Green Star Performance Launch in Auckland on the 29th November
