eHaus Euro - Certified Passive House Plus (2017)
This striking family home was the first in Australasia to be certified Passive House Plus. Its performance has been monitored and reported on and it also featured in the book Positive Energy Homes. The buildings simple rectangular form maximises energy efficiency and ease of construction. It was designed and sized to match the Ecoblock Wall system with minimum waste. The house opens up to impressive mountain views to the north. A bold use of colour inside adds immediate character and personalises the bedrooms for each of the family’s three teenage boys. The home provides excellent year round comfort including during the summer months, – no active cooling is required. This has been achieved in part due to the modest amounts of glazing on the eastern and western walls and well sized overhangs to the north.
NB: Initially certified as a Passive House by BRE UK in 2014. Sustainable Engineering subsequently certified it as a Passive House Plus in 2017

About the
Professional
At eHaus, we live like efficiency is our point, and intelligent construction our norm. We live like our environment is a privilege and protecting it our responsibility. We live like New Zealanders are our passion, and ingenuity is our response.
eHaus was established in 2010 by Jon Iliffe and Baden & Glenda Brown with the dream of creating a New Zealand owned and operated specialist design and construction company using PassivHaus build and design principles.
Jon, a Mechanical Production Engineer from Rolls Royce Motors, arrived in New Zealand and looking to build a family home went seeking out alternative options and found the PassivHaus way.
Baden, a master builder of 20 years, disillusioned with the poor performance of the high-end homes he was building for clients, also was seeking other options, and discovered PassivHaus. Together, with Jon and Glenda - Financial director, eHaus was formed.
Our eHaus team is made up of some of the country's best Passive House builders, architects and designers who are redefining the way kiwis live, one home at a time. Our team of professionals work together to see your dreams come to reality.
Today eHaus is recognised as award winning and New Zealand leaders in PassivHaus design and construction. Find out more about eHaus and our teams here: https://ehaus.co.nz/
