Description / Additional Information

Describe the key innovation and technology aspects of the project

Project Narrative

Design that minimizes TEDI and EUI Optimization of IAQ, natural daylighting, thermal comfort Use of University’s Co-Gen system for heating and cooling; new active systems for supplementary ventilation. Supplementary heating + cooling using radiant ceiling panels and slabs Night flush system; tempering exposed concrete thermal mass using central vent stacks and solar chimneys. Operable window vents controlled through a BAS Supplemental UFAD displacement ventilation Network of façade of sensors Horizontal PV and Vertical BIPV
