Correctly sizing, and being mindful of the installation and maintenance requirements of the systems required for energy and resource efficient homes is essential to a home that is comfortable and enjoyable to live in.

Systems Expertise

We ensure our client’s solar electric, rainwater catchment and gray water systems meet their individual lifestyle requirements.


  • Solar PV Systems: Size and design electrical generation systems and appropriate storage capacity based on the site’s available solar / wind energy.
  • Rainwater Catchment Systems: Size and design rainwater collection and storage capacity, including potable water filtration and purification if desired, based on the site’s annual precipitation pattern and amounts.
  • Gray Water Systems: Separate gray water fixtures from black water fixtures in plumbing design, with a valve between the two fixture types to use gray water for garden irrigation and occasionally dump it into the septic system when necessary.
