SANS 10400-XA Rational Assessment and Design

Offering Rational Building Energy Assessments resulting in design freedom and appreciable cost savings.

Greenplan offers a comprehensive and advanced service regarding building energy assessments. This evaluates the performance of a building for every hour of the year, using representative weather data and incorporating not just the fenestration, but the complete building envelope and aspects like hot water generation, cooling and heating energy, lighting etc.

Greenplan has completed SANS 10400-XA assessments for more than 1500 buildings

Our methodology gives design freedom back to Architects as different design aspects can be weighed up against one another to provide an acceptable energy solution.
