G7/VM1 Daylight Modelling Across New Zealand
We provide G7 daylight modelling and G7/VM1 compliance reports for residential, commercial, apartment, education, and care projects across New Zealand.
Our daylight analysis services assess natural light performance, daylight factor compliance, glazing performance, and awareness of the outside environment requirements under Clause G7 Natural Light of the New Zealand Building Code.
