H1 Reports
We specialize in creating H1 reports showing compliance with the latest H1 clauses of the New Zealand Building code for energy efficiency in commercial and residential buildings, no matter the complexity. Our team are experts in proving compliance using the modelling method, calculation method, and schedule method set out in H1/AS1, 5th edition, H1/AS2, 1st edition, H1/VM1, 5th edition, H1/VM2, 1st edition, H1/VM3, 1st edition.
We care about your goals, whether it be reducing construction costs or helping you design a state of the art energy efficient building.
If you need an H1 report or advice on what's required to make your building comply, while achieving your desired design outcomes, get in touch now.

Cost Saving Review
If you are interested in saving costs in construction while still achieving compliance with H1 get in touch. This can including looking at removing slab edge insulation, reducing the glazing specification, reducing the roof insulation, and other outcomes to reduce construction costs for your project.
HVAC Equipment Sizing and Space Temperature
As part of the modelling method we can use the same building model to simulate heating and cooling loads for HVAC equipment sizing. We also can look at space temperature profiles to see how comfortable your house will be to live in.
Our Services
1
Schedule Method
This method considers only the heating energy performance of your building design and all windows, walls, roof, floors, and doors must meet or exceed the minimum thermal performance requirements set out in clause H1. This method allows for the least cost savings.
2
Calculation Method
This method considers only the heating energy performance of your building design and provides some flexibility in the thermal performance of building constructions. You can get some cost savings with this method.
3
Modelling Method
This method assesses both the heating and cooling energy performance of your building design through computer simulation models. By considering factors such as insulation, building constructions, solar shading, and solar performance of glazing, this method provides the most flexibility and often the best construction cost savings.
We highly recommend using the Modelling Method as there are no limitation on glazing, insulation and there is a greater flexibility for cost savings and building aesthetics. Some of the larger savings we have been able to achieve are with the glazing type and size as well as the removal of slab edge insulation.
