Unlock full compliance with H1, E3, G4 and G5 while improving comfort, durability, and energy efficiency. BEO Buildingscience offers a fixed-fee consulting service designed for high-performance homes and small commercial buildings across New Zealand. From energy modelling and moisture analysis to ventilation and airtightness strategy — we deliver everything you need to support your Building Consent application and design performance goals.

Comprehensive Building Code Compliance & Performance Consulting for New Zealand Projects

Achieve NZ Building Code Compliance in One Expert Package

  • H1 Energy Efficiency (VM1 )

    Our consultants use advanced energy modelling to deliver fully compliant H1 reports for residential and commercial buildings. We optimise insulation levels, balance U-values, and assess solar gains to ensure performance and cost-efficiency.

  • E3 Internal Moisture Control

    We model hygrothermal behaviour using WUFI Pro to identify and prevent condensation risk in walls, roofs, and tricky junctions. All calculations follow ASHRAE 160 and are tailored to local climate data and construction methods.

  • G4 and G5: Thermal Comfort and Ventilation Strategy

    We assess thermal comfort using heating and cooling demand simulations and provide ventilation layout recommendations that support consistent temperatures, fresh air delivery and compliance with G4. Our strategies aim to reduce overheating, draughts, and occupant discomfort.

Design Optimisation for Thermal Envelope and Solar Gain

We go beyond compliance to help you reduce heating and cooling needs through smart design. Optimising window placement, overhangs, shading, and massing can significantly lower long-term energy use.

U-value Balancing and Thermal Bridge Mitigation

Our detail reviews include thermal bridge calculations and practical fixes for junctions, corners, penetrations and slab edges — key areas often overlooked during design.

Heating and Cooling Demand Reduction Strategy

We simulate annual heating and cooling demand based on location, air permeability and ventilation approach. This ensures your building performs as intended, not just on paper.
