Our Testing Services
During construction and through life, our physical, on-site testing services will provide objective and factual evidence regarding the performance of your building. Our testing services include:
Blower Door Testing
Air leakage is directly proportional to building energy consumption and operational costs. Testing air leakage quantities (ie. the quality of the building air barrier) can be a good indicator of future energy costs. The blower door test also helps to indicate locations of unintentional air loss that may be costing you money.
Our building scientists and energy auditors will help you determine the airtightness of your building.
We are dedicated to assist you deliver healthy, energy efficient and cost effective buildings.
On-site testing is becoming increasingly valuable and prevalent in the NZ Construction industry. We provide physical, on-site testing that involves using a blower-door and a spray rack kit to simulate a cyclone to identify if the building performs as required. This testing de-risks the project by quantifiably demonstrating building performance and is conducted during the construction programme to minimise the impact of any required rework. Verification testing has been conspicuously absent from the New Zealand industry. Booth testing in laboratory conditions before construction says little about what is ultimately built. We can test to New Zealand and international standards on site anywhere in New Zealand. If you would like to know more about our on-site physical testing services please contact us immediately.

Indoor Air Quality Testing
The fundamental key to maintaining healthy buildings and occupants is knowing when,why and how you should determine the indoor air quality.
We can test your appartment, your house or your workplace.The process follows a systematic assesment of air quality in your building using a variaty of techniques.
Contact us if you have any concerns about the quality of air in your workplace, office or home.
Comprehensive investigations, while extremely useful to identify issues with a building and its components, only provide a snap shot of the building at the time of inspection. Learning how a building functions on a daily basis; its wetting and drying cycles allow us to gain insight into the quality of construction and to more accurately pinpoint current or potential problems. That is where hygrothermal monitoring comes in. Hygrothermal monitoring is essentially the collection of moisture and temperature conditions within the building assemblies over a given amount of time (this could range anywhere from one month to one year).
Sensors embedded within the assemblies take regular measurements of the relative humidity and temperature within the cavity, pressure differences across the cladding and the moisture content of timber components. This data is then transmitted to our computers in the office where we can format and analyse the information – looking for patterns to better understand how the building is performing on a day-to-day basis.
The type and number of sensors used on a project is tailored to suit the goals and scope of that project. However, we try to incorporate a good range of sensors in several locations around the structure to obtain an overall perspective of the building’s performance.
