Designing to Lower Energy is the Foundation of a Good Home.
Aava Projects provides expert verification and Building Energy Modelling (BEM) for Aotearoa—specializing in 60%+ energy reduction through simple, high-impact design steps.
Effortless Comfort without the Penalty
Maximise your level of comfort during the cold and warm months, pairing efficiency with superior indoor environments. Being too hot or cold in your home is a notion of the past.
Let the Building do the Work…Not your Bank Account
Focusing on the structure first puts your money where it’s needed most. More efficient components used in the right place in your building may be offset by the elimination of expensive traditional heating and cooling systems
Your Impact on the Environment
Passive or Low Energy Standard buildings use extremely little primary energy, leaving resources for future generations with less environmental impact.
