Hi,

Use the form on the right to send us a message.

We've received a number of enquiries from people who are looking for help with their own projects and we're thinking of ways in which we can offer that help.

If you have a project you'd like to discuss please let us know what stage of concept or design you're at, when you hope to start build, and where your house will be built.

If you have a media enquiry please click here to view previous coverage, media packs, and a contact form to get in touch with the comms team. 

Thanks,
The ZEH team.

PV roof and latest

Shay Brazier

Over the last couple of weeks I have been continuing my research into how we will integrate the photovoltaic (PV) system into the roof. Internationally there are many PV products that double as a roofing material, in NZ however there is only one that I know of. It uses amorphous silicon, which due to the lower efficiencies will not allow us to fit enough on the roof to generate the sufficient energy to meet our energy requirements over the year.

I have summarised some of the thinking so far on PV on a new page in the systems section. The image below shows the areas of the north roof that will be occupied by solar water heating panels and PV modules. The chart summaries the expected energy usage over the year and how this corresponds to the energy generation from the solar PV.

Other areas of the design that we have been working on over the last couple of weeks are:

  • Heat recover ventilation systems
  • Rain water and grey water systems
  • Roofing materials
    • Refined energy simulation modelling for modified window sizes
