Sustainable Thinking
Our high performing homes are the result of precise planning, intentional design and scientific modelling.
In every eHaus sustainability, innovation and thoughtful design are woven together to create homes built to an unreasonably high performance standard.
The science behind a comfier home
Energy efficiency is woven into the fabric of every eHaus using PHPP software. Designed for building homes to a rigorous international standard, the tool allows us to apply similarly high standards of efficiency to the design of your eHaus, determine the most suitable form of the building, and instantly show the impact of design decisions on the building's energy efficiency.
The importance of
Design stage modelling
Energy modelling is the most important part of the eHaus design process. It allows us to model the design of your home to accurately predict performance. It can tell us whether one room will be colder than another or whether your home might overheat in summer.
Built for a specific climate zone
We design eHaus’ specifically for 19 different climate zones in New Zealand. Why? Because a warm home in Invercargill requires a different level of insulation and ventilation than a home in Kaitaia. Using detailed NIWA data, each zone accounts for factors like the average temperature, altitude, and inland or coastal variations.
The features that make
an eHaus exceptional
Modelled using PHPP
Every eHaus is measured to international standards for energy efficiency and comfort while still on the plans.
Draught Free
eHaus’ are built to stop draughts and prevent air leaks, saving you money and creating a beautiful, quiet space to enjoy.
Superior insulation
Each eHaus is insulated to match your regional climate. With a fully insulated slab and thicker high-performance walls, eHaus are made to keep more heat in.
Thermally efficient joinery
Beautifully engineered with double or triple glazing to reduce heat loss, condensation, draughts and mould.
MINIMAL or zero thermal bridges
An eHaus is designed with either minimal or no thermal bridges – one of the most significant sources of energy loss in any home.
Heat savings
Smart energy modelling helps us to accurately calculate just how much heat energy every eHaus will save compared to a similarly sized standard home, built in the same climate region.

Carbon savings
When you choose an eHaus you're making a difference for the planet and for future generations. Find out how an eHaus reduces your carbon emissions from day one.
