Helping Your Building Achieve SANS Compliance
Don't let inadequate glazing and shading specifications prevent your building from achieving SANS 10400-XA compliance. Our consultancy ensures your building's sun control strategy meets every SANS requirement.
Why SANS Compliance Trips Up Even Experienced Architects
South Africa's National Building Regulations demand rigorous compliance for energy efficiency. Yet these requirements are among the most technical — and most frequently failed — elements of building submissions.
Municipal Rejections
Each rejection cycle costs weeks of delays and erodes client confidence. We eliminate this risk entirely.
Complex Physics
The interplay between U-values, SHGC, and shading coefficients demands specialist thermal modelling knowledge.
Certification Risk
Inadequate sun control can disqualify a building from Green Star, EDGE, or Net Zero certifications.
Understanding SANS Requirements
South Africa's building energy regulations are complex and interconnected. Here's what your building needs to comply with — and how we ensure it does.
SANS 10400-XA
The primary National Building Regulation governing energy efficiency in South African buildings. It sets mandatory requirements for the thermal performance of building envelopes.
- Maximum fenestration U-values
- Solar Heat Gain Coefficient limits
- Mandatory shading for orientations
SANS 204
This standard provides the design requirements and deemed-to-satisfy rules for energy efficiency in buildings. It specifies the performance criteria for a building's glazing and insulation.
- Window-to-wall ratio limitations
- Glazing performance specifications
- External and internal shading
From Assessment to Guaranteed Approval
Our structured five-step process ensures your building's sun control and glazing specifications achieve full SANS compliance — first time, every time.
Building & Glazing Assessment
We analyse your building's orientation, facade design, glazing schedule, and window-to-wall ratios. Every fenestration element is mapped against SANS 10400-XA and SANS 204 requirements to identify where the building's current design falls short of compliance.
Thermal Performance Modelling
Using specialist knowledge of U-values, Solar Heat Gain Coefficients (SHGC), and shading coefficients, we model the thermal performance of your glazing and sun control systems to ensure they meet energy efficiency thresholds.
Sun Control Product Selection
We specify the optimal combination of Low-E glazing, internal/external blinds, and shading devices to help the building achieve its SANS 10400-XA energy targets. Product selection is driven by the building's compliance requirements, orientation, and your project's aesthetic and budget parameters.
Compliance Documentation
We produce comprehensive building compliance documentation including energy performance calculations, shading factor analyses, glazing schedules, and all supporting evidence required to demonstrate that the building meets SANS 10400-XA requirements for municipal plan approval.
Submission Support & Approval
We support you through the municipal submission process, responding to any queries from plan examiners and ensuring first-time building approval. Our 100% track record of successful building SANS compliance submissions means zero rejections and zero delays for your project.
