The New Zealand Energy Efficiency and Conservation Authority (EECA) has developed a Home Energy Rating Scheme (HERS) for New Zealand households based on software simulation of energy loss and demand. The software requires hourly data to represent the differentclimates zones around New Zealand, especially for larger population centres. These climate data consist of hourly records for an artificial year created from twelve representative months. Please note: The data is publicly-funded data provided by the National Institute of Water and Atmospheric Research Limited (NIWA) and no person or entity may charge for its supply or use. While NIWA has exercised reasonable care and skill in the preparation and collation of the data files, the data is supplied on an ‘as is’ basis, without warranty of any kind. NIWA accepts no liability for any direct, indirect, special or consequential damages, loss, damage or cost arising from and relating to, any use of the data and/or the information associated with it. Full terms and conditions governing the use of the data can be found at: http://edenz.niwa.co.nz/about/terms.

Wintec have been building two to three bedroom houses with students for the last 24 years these houses are then on sold into the community as affordable housing.
The houses were standard transportable gable or hip roofed hardie blank weather board homes.
These houses were great to build with the students covering all aspects of their learning criteria. The houses were also a popular item within the community requiring a waiting list for perspective buyers.
However Wintec wanted to create a new design that embraced the latest building technologies and current building design trends.
This project and philosophy was shared with the students who designed and built the new mono pitch design.
This was a very inspiring project that fed Wintecs build environment and carpentry department’s philosophy of constant improvement.
Reflection of design and materials was constantly discussed and shared with the students and improvements were implemented and constructed.
These changes were a reflection of what was happening in industry i.e. insulation improvements, double glazing, product changes etc.
It became apparent – and some thing as a school we were very interested in – embracing was the growth and awareness of sustainability and energy consumption within the construction industry.
This interest grew and from that interest two projects evolved within Wintec; The Eco Village and our first entry into the SHAC challenge 09.
SHAC house 09 was a one of design designed within the Built environment school by Trevor Wyatt and built environment students. The project journey was shared within the Shac competition website, students, industry and the community.
The Eco village is another sustainable initiative taking place at Wintec and one we are very excited about. Wintec would like to further develop the eco village house design as our entry into the Shac Challenge 2010.
Further reflecting on the Eco Village house design, as a base model, and making ongoing design, material selection and energy consumption improvements will be part of our continuous improvement philosophy.
With our involvement in the shac project we would like to showcase some of the exciting developments we have made in regards to imbedding sustainable practices in the construction of the eco village and eco houses. We would also like to:
Make improvements to these developments, (current Eco house design), with student, industry and shac team input. Reflect on the developments made, what was good what was not so good.
Form closer relationships within the trade departments by sharing an overall goal of sustainable design and practices and imbedding this within are current teaching curriculum.
Constantly reviewing materials and product use and investigating more sustainable options.
Creating regenerative communities by;
Demonstrating new residential house technologies re energy consumption.
Contributing an improved house design to the student village community. With emphasis on improved material selection bathroom, WC and laundry layout and better use of internal layout where possible.
Monitoring the Energy consumption of the improved house design and sharing this information for the benefit of the wider community and Shac teams.
Creating a delightful building with emphasis on its surroundings, colours function and creative use of space.
Work with industry and community in achieving our goals.
Vision of regenerative neighbourhood
A regenerative community is a sustainably aware community. The power of education and knowledge is the energy source that will regenerate and power communities for a better future.
Creating a student village as a base model for sustainability, energy consumption research, discussion and debate will ultimately promote the awareness and knowledge required to educate communities and the work force of tomorrow.
Creating an ongoing educational process that promotes the benefits and skills required in the regenerative use of energy, waste, water, fuels, construction materials and techniques are all an integral part of building these communities
The construction of the house will be by Wintec pre trade carpentry plumbing and electrical students at the Avalon campus.
The house will be constructed under cover and transportable. Once completed the house will be relocated to the Eco village site to provide student accommodation and to be monitored for its energy consumption
The site has good orientation to the north with the length of the house located on a east to west axis. The ground profile is soft with a high water table requiring a driven pile foundation.
The building design is a 100m2 transportable residential home constructed from building materials readily available and common to the current building market.
Emphasis will be on a multipurpose floor plan a design that can; comfortably accommodate a family of four, be used for shared accommodation purposes’, holiday homes, or be adaptable for class room or community type buildings.
One of the key ingredients in the construction of the house will be the services and facilities we will fit the house out with. This is an area essential to energy consumption and an area we would like to research and monitor.
The building design will be true to its roots with its main objective been to ensure we keep with the fundamentals of our current teaching curriculum in light timber frame construction.
The skills and ability required for the construction of the house are to be associated with the student profile and community type labour resource.
The ultimate goal is to create a building that is affordable energy efficient and have the ability for multipurpose use.The construction process and material selection will be simple to construct .This will allow small rural community; groups with a small amount of skilled labour and collaborative community know how the ability to; be able to afford and construct houses for families, class rooms for schools, and small community buildings.
Another essential ingredient will be the information and educational resources created by reflecting on the journey travelled in creating the house and student village.
This reflection will continue the philosophy of self improvement and will help advice communities on the what, how and why of creating regenerative communities.
Funding the house build
The estimated cost of the house dependent of foundation design is $1.500 – $1.800 per m2
The majority of the construction labour is to be done by students.
Partial sponsorship by eco village industry partners ECCA and WEL energy.
Supplier sponsorship, (currently) Rinnai hot water systems.
Design support from Rod Yeoman, Ros Epsom, Tina Booth .
