Mauritius Villa Project Achieves Net Zero Design: Energy Certification
We are proud to announce that Mauritius Villa, Plot No. 95, Mont Choisy bois des champs Mauritius, located within a larger residential community at Bois de Champs, Mauritius, has officially achieved GNFZ’s Net Zero Design: Energy certification!
This certification validates that the villa has been designed and documented to perform as a net zero energy building. The design phase is complete, and construction is now underway.
The villa has been carefully designed to achieve outstanding energy performance. Its expected annual energy consumption is 13,439 kWh, which translates to an Energy Performance Index (EPI) of just 30 kWh per square meter — almost half the baseline of 57.25 kWh/sq.m typically observed in similar residential projects. This level of efficiency results in projected Scope 2 emissions of 11,691.93 kgCO₂e per year.
The villa is designed not only to neutralize its energy-related emissions but also to produce a small surplus of clean energy, positioning it as a carbon-positive development. The design incorporates an 8 kWp rooftop solar PV system, expected to generate approximately 14,460 kWh annually. This renewable energy contribution avoids an estimated 12,580.20 kgCO₂e of emissions per year, leading to a net positive outcome of around 888 kgCO₂e annually.
Several efficiency measures have been embedded into the design to achieve this performance. The villa references ASHRAE 90.1-2016 as its baseline standard, and surpasses it through a combination of advanced technologies and optimized systems. A Variable Refrigerant Flow (VRF) HVAC system with a coefficient of performance (COP) of 3.7 ensures efficient climate control. The lighting system has been designed to operate at a reduced power density of just 4.5 W/m², compared with the baseline of 9.4 W/m². Additionally, high-performance double-glazed units (DGU) with a solar heat gain coefficient (SHGC) of 0.22 have been incorporated to enhance thermal comfort and reduce energy loads.
The certification awarded to Mauritius Villa’s Plot No. 95 is for its design phase. It confirms that the project has been planned and documented with the technical capacity to operate as a net zero energy building once completed and occupied. In the next stage, after construction is finished and operational data is collected, the villa will be eligible to pursue Net Zero Operations: Energy certification to validate its real-world performance.
This milestone underscores the commitment of the project team to advance sustainable living in Mauritius. By integrating energy efficiency measures and renewable energy strategies into its design, Mauritius Villa’s Plot No. 95 demonstrates how a residential development can move beyond reducing its environmental footprint to actively contributing to positive climate outcomes.
