At SiiGMATIC, we provide certified NatHERS energy rating assessments to help builders, architects, and homeowners meet 6-star and 7-star energy efficiency standards for residential buildings. These assessments support compliance with the National Construction Code (NCC), which mandates minimum thermal performance for new homes and major renovations. Using accredited software, we model a building’s thermal performance and assign a NatHERS star rating. If a design falls short, we offer targeted recommendations on insulation, glazing, orientation, ventilation, and materials, along with expert guidance on selecting energy-efficient windows, doors, and hardware to improve overall performance.

In addition to assessments, SiiGMATIC operates a NATA-accredited testing laboratory and is an AFRC-accredited WERS rating facility, allowing us to evaluate the thermal performance of construction materials with precision. We provide official NatHERS energy rating reports and compliance documentation needed for building permits, along with expert advice to ensure your project aligns with the latest efficiency requirements. Whether it’s a new build, extension, or renovation, we deliver a complete service that supports compliance, improves energy performance, and helps reduce long-term heating and cooling costs.
