New Zealand Climate Data for Building Simulation

  

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.

Build your own home – Wairarapa Times-Age

  

 

 

Masterton home eco-aware – Local News – Wairarapa Times-Age.

In 2007, Steven, an industrial design engineer, began work on the eco-friendly house he would take three years to build with his own hands.

He even built the kitchen and every piece of furniture from the shelving to the beds, and fitted solar panels, which store 2000 watts of energy.

“When building our house, there were moments in the process when we had choices, like when we were deciding on our insulation. We decided to go with recycled insulation because it’s better for the environment, and it’s a nice material to work with – you’re not working with things like fibreglass.

“We also positioned the house to the north, so the sun shines through the big windows and warms up the place.”

He said building an eco-friendly house is “not rocket science”, it is just about thinking more carefully about your choices and how they affect your wallet as well as the environment.

“These ideas have been around for ages, it’s just being aware of them when you’re building a house, or doing anything else in life, like driving. If you drive 90km/h instead of 100km/h, you can save about 15 per cent of fuel, and you also have the opportunity to relax and enjoy the beautiful scenery instead of rushing.”
