Brad Crowley

Senior Manager - Buildings & Communities - NZGBC

Managing the Green Star rating tool Brad assists the team and identifies new opportunities to use the quiver of Green Star tools (Design and As-Built, Performance, Interior, Communities) to make buildings better.

While getting his Geography Master’s degree back in the late 1990s Brad first heard about Sustainability and Green Buildings. Ever since he has been advocating for green buildings and sustainability including starting up his own business creating and installing rainwater catchment systems in Portland, Oregon.  Brad has a positive outlook on seeing what he and NZGBC can do to encourage healthier and more environmentally friendly buildings and communities in Aotearoa.

Tech support and Education Manager - Proclima Oceania

Jon oversees Pro Clima’s education offering across Australia and New Zealand. He brings his knowledge of on-tools building combined with his experience in product analysis to clearly point out the areas of our building code and practices that need improvement.

His recent research into retrofitting external insulation onto occupied buildings is starting to generate interest where the typical cost, disruption, high complexity and low performance of renovation needs to be changed for buildings and people.

Mike Lyon

Application Engineer - AeroBarrier

Working for The Element Group, an energy consulting firm, he spearheaded the growth of the company – expanding from a handful of clients across twelve states and over 300 multifamily and single family low incoming housing projects requiring specific energy and sustainable certifications.

In the summer of 2018 a demonstration of a new advanced air sealing application, AeroBarrier, convinced Mike and his colleagues this was the positive disruption to advance building techniques the industry needed. After investing in the technology, two years and 400+ AeroBarrier seals later, Mike felt it was time to personally make a larger impact, contribute not just on a regional scale for AeroBarrier but on a national scale. 

Les Gates

Design Manager - Hawkins

Les Gates is a Design Manager for Hawkins Construction and has worked in construction for the past 17 years in New Zealand and London.

Primarily site-based, Les prefers living the design and construction process at the coal face, on site with the practical knowledge of those around him, being able to see firsthand what works and what doesn't. With a keen interest in architecture and sustainable building practices, he enjoys the challenges and variety that commercial construction affords.

Recently Les has helped complete the University of Auckland Human Sciences Building (B201) project - a groundbreaking adaptive reuse project which was awarded 93 points Green Star Design points (as-built pending). Part of this project's Green Star innovation credit involved testing and proving the building's airtightness. Les shares his experiences managing this process from inception to completion.
