VE Gaia

Building climate resilience from the early design stages

VE Gaia: Early Stage Design Analysis

Buildings are responsible for 39% of energy related CO2 emissions. By integrating building performance from the earliest stages of design, alongside creativity and vision, it is possible to significantly reduce the energy and environmental impacts of our buildings to make a real impact.

This is our moment - as building designers, architects and engineers - to play our part. Together we can make a difference.

Our Commitment to Industry Challenges

RIBA 2030 Challenge

The RIBA 2030 Climate Challenge focuses on four key areas around building design and emissions. 

As users of the IESVE and strong advocates of the RIBA 2030 Climate Challenge, Mesh Energy explain the Challenge and how they use the IESVE to help aspiring projects meet the rigorous targets set out by RIBA.


AIA 2030 Challenge

This new IESVE software integration supports the AIA 2030 Challenge, such that all new buildings, developments, and major renovations shall be carbon-neutral by 2030 by way of sustainable design. Users can now track their progress against the AIA 2030 goals with this streamlined upload.
