"The opportunities that are now in front of us are about building a green city, an energy efficient city, one where transportation infrastructure works a whole lot better than it did prior. It's such a unique opportunity."
Opus is one of four finalists, alongside Christchurch Energy Action, Tait Communications and TM Consultants, in a special category created this year for the EECA Awards to recognise people, organisations and projects working to improve energy use in Christchurch's rebuild.
Bretherton says the biennial EECA Awards, which celebrate excellence and innovation in energy efficiency or renewable energy, affirm that the work Opus is doing is leading edge and driving change in the marketplace.
Opus' entry in EECA's Christchurch Energy Champion Award contains diverse projects - from energy efficiency technology for schools, a riverside promenade through to large-scale commercial developments, including new offices for the firm.
While he finds it difficult to single out a particular project Bretherton is proud of the work Opus has done for Tait Communications on eight acres of rural land next to the company's existing manufacturing facility.
Bretherton says Tait had an aspirational masterplan for its proposed campus and surrounding land, including a desire to cut energy costs by 40 per cent, but a collaborative workshop in conjunction with the client really teased out what was important to them.
"You can create a vision but fundamentally the business drivers behind that need to stick as well."
