David has a keen interest in improving the efficiency and sustainability of the built environment.
He has worked on many projects to capture and reuse rain water, developed district energy systems utilising a range of different energy sources, modelled passive systems such as stack ventilation and thermal mass affects on air movement and cooling, and designed a large zero GWP and ODP heatpump system using Ammonia as the refrigerant.
David is also passionate about improving building envelopes and the materials used for them. He enjoys working with architects and designers to improve the efficiency of the envelope for thermal, moisture and air movement.

Burton Hodge
Fire Engineering Leader - Auckland 
Burton took a Green Star introduction course in 2008. He has since been involved in the Waste Management offices and workshop project which achieved a Green Star rating. While working in England he also took part in an initiative to incorporate the United Nations Sustainability Goals into Fire Engineering practice.

Joe Quad

Specialist Sustainability Engineer - Auckland

Graduating with a BE Mechanical from Concordia University in 2011, Joe worked as a mechanical/hydraulic consultant while building his knowledge of sustainability engineering. During this time, he achieved accreditation as a LEED Green Associate and Certified PassivHaus Designer. LEED Green Associates are internationally recognised for their comprehensive knowledge and expertise in sustainable design. Joe proved this capability in his contribution to projects such as the Clayton Heights Community Centre; Canada's largest facility to achieve PassivHaus Certification. Joe has also completed his assessment to become a Green Star Accredited Professional, making him an invaluable asset to any project seeking Green Star certification.

NABERSNZ

The NABERSNZ rating scheme was implemented in 2015 and can be used to assess how well a building uses its energy. It uses a similar ‘star’ rating system to the Green Star system, ranging from 0-6 stars. It acts as a post-occupancy tool and aims to provide a ‘real world’ rating system.

Cosgroves have accrediated staff who are able to provide feedback on the use of the NABERSNZ Rating process in order to achieve a certified rating for their clients.

Peter Affleck
Mechanical / Fire Protection Engineer - Wellington
Ever since fitting energy saver bulbs in his family home as a high school student, Peter has demonstrated a strong interest in reducing energy use and costs. With subsequent training and over 20 years industry experience in building services engineering, Peter’s skills now allow for far greater energy efficiency improvements than just changing light bulbs.
Peter’s experience in contractor and consultancy roles produces practical design solutions that work. He believes that “NABERSNZ will be great for engaging owners and tenants in the active improvement of energy consumption, with the bonus of seeing real results and reducing energy bills.”

Anna Kosiel
Mechanical and Hydraulic Engineer - Christchurch 
Anna has completed the NABERSNZ Assessor training in 2016, and since then completed numerous ratings for buildings in Christchurch and Auckland. She is also familiar with Green Star ratings and was involved in Green Star driven design of a new Church in Lincoln, in line with a new custom tool developed for Catholic Diocese of Christchurch.
Specialising in building performance modelling, Anna was also involved in various energy efficiency assessments for new and existing buildings in collaboration with EECA, while successfully obtaining capital grants for implementation of energy efficient initiatives.
As a senior mechanical engineer, she ensures that energy consumption and emissions are considered during design stage, and where financially viable, energy conservation and carbon saving measures are implemented. She has recently completed the Energy Auditor Training to gain further understanding of new standards and requirements for various types of audits.

EECA FUNDING

Cosgroves work closely with EECA approved energy consultants to provide EECA funded feasibility studies, design reviews and post-occupancy energy monitoring on commercial projects across New Zealand.

PROJECTS

Selwyn District Council Headquarters
Selwyn District Council's main office located in Rolleston, incorporates many green engineering features which minimise waste and energy consumption whilst maximising the use of sustainable materials. Systems include high efficiency solar collectors for domestic hot water generation, rainwater harvesting, mixed mode ventilation with passive vents, and under-floor heating by way of a high efficiency heat pump connected to the Council water reticulation.

Man Street Carpark, Queenstown
CFD modelling was also successfully applied to an alternative car park ventilation design using impulse ventilation: the first installation of its type in Australasia. By showing that adequate air quality could be achieved, ventilation installation costs were effectively halved.

Waste Management Headquarters, Auckland
A large mixed use site incorporating a large commercial office building which serves as Waste Management’s Headquarters as well as industrial workshops and wash down buildings, a large staff car park and a large yard for bin laydown and truck parking.  The project is a pilot project for the newly created Design and As-Built Rating tool and has been designed to achieve a 5 Star Green Star Rating.   

Camp Glenorchy
Camp Glenorchy, at the gateway to Mount Aspiring National Park, is New Zealand’s most sustainably designed and operated visitor accommodation. It was built to reflect the imperatives of the Living Building Challenge, the most rigorous sustainability standard in the world. Regenerative spaces that connect occupants to light, air, food, nature, and community and self-sufficient while remaining within the resource limits of their site are the basic principles of a Living Building Challenge project

PWC Centre, Christchurch
This high-profile Christchurch development required a sustainable A-grade design to create a modern, high-quality professional environment for top-tier anchor tenants PWC and Chapman Tripp. The building was designed to a 4.5* NABERSNZ rating, requiring extensive thermal and energy modelling using IES Virtual Environment. 

Press House, Christchurch
The new building built for The Press on Gloucester Street in Christchurch consisted of a new Green Star 4 Star rated eight level building with over 7,000m² of floor area providing offices and car parking.
