AI · Retrofit
RetroFit-AI

Machine-learning model recommending optimal retrofit packages for Canadian housing archetypes based on climate zone, building age, and budget.

Simulation · Energy
VCWGv1.4.9

The Vertical City Weather Generator (VCWG) is a software that predicts the urban micro-climate and building performance variables in relation to a nearby rural climate given the urban charac- teristics. VCWG predicts vertical prpffiles of temperature, wind speed, humidity, and turbulence kinetic energy as well as the building energy performance metrics in an urban area.

Optimization
VCWGv1.6.1

Multi-objective optimization engine balancing cost, emissions reduction
