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

Key Facts

• The project was part of GIZ’s Financing Energy for Low-carbon Investment – Cities Advisory Facility (FELICITY) where pilot projects are undertaken with a view to securing project financing by the European Investment Bank
• RED worked in collaboration with Tractebel to deliver the project
• RED modelled a variety of retro-fit performance upgrades including, reflective roof coatings, brise soleil, LED lighting & controls, PV and battery storage in order to quantify financial and thermal comfort benefits to pupils and teachers
• RED modelled cost-effective solutions resulting in potential energy efficiency savings of 44%
