Lindsay and his wife Dale had been researching ways to design an energy-efficient home for many years before they retired and moved from Perth to beautiful Kerikeri. They approached Paul at Spooner Architectural Services with their ideas. Bevin MacCarthy, a certified builder from Bay Builders, was commissioned with the project.
How was this project implemented?
A dedicated airtightness and vapour control layer, INTELLO® PLUS Intelligent Air Barrier, has been installed to help minimise air leakage from the building. Once the airtightness layer had been installed, a Blower Door test was performed which resulted in a performance of 0.89 air changes per hour at 50 Pascals pressure difference. As a comparison, standard New Zealand homes built to code today are generally achieving 5 – 7 air changes per hour at 50 Pascals.
Lindsay and Dale wanted an energy-efficient home and succeeded. What they have created is a comfortable, healthy, easy-to-heat home where they can throw open all the doors and windows whenever they like and shut out the weather completely when they need to.
We had a feeling houses could perform better than they do, and now thanks to Bay Builders we have proven it, says Lindsay.
It is a bit like my car – weather proof, wind proof, ventilated, comfortable.

Blower Door
A Blower Door is a machine used to measure building airtightness. It can also measure airflow between building zones, test ductwork airtightness, and physically locate air leakage sites in the building envelope.

Intelligent Airtightness
Moisture damage to structures and protection measures
-
Moisture can enter into building structures in many different ways, and it is impossible to prevent a certain level of moisture loading.
-
However, if moisture levels are too high, moisture damage to structures can result.
-
To ensure a structure is protected against moisture damage, the drying reserves possessed by the building component are much more important than the degree of tightness of the vapour check.
-
Vapour barriers with high diffusion resistances allow for barely any drying from the component to the inside.
A high degree of protection against moisture damage to building structures can be achieved with intelligent airtightness.
