Antonio Giudice School

Publicly funded schools in Brazil have little investment and relatively poor construction standards in comparison to western countries. GIZ commissioned Tractebel/RED to undertake a feasibility assessment of building performance upgrades, to reduce energy bills and improve thermal comfort for the pupils, with a view to rolling out improvements to schools across the country.

The key sustainability services included:

  • Site energy audit
  • Technical research in the local market for photo-voltaic systems & battery storage
  • Thermal modelling of performance upgrades to an existing school in Porto Alegre, Brazil
  • Financial analysis of performance upgrades

A detailed site survey of the school was undertaken and the survey was used to construct a thermal model. RED calibrated the thermal model using metered data to create a digital twin of the school which was used to accurately model the effectiveness of a variety of active and passive building performance upgrades . Thermal Comfort improvements (PPD & PMV) were assessed in accordance with ISO 7730:2005
