The retrofitting project of the Chemical Engineering building at NTUA aims at reducing
energy consumption and increasing thermal and lighting comfort for the users, while allocating part of the common spaces to other uses for
which adequate shelter is needed.
Retrofit features:
Integrated PV/passive solar system (southern façades, attached sunspace, covered atrium).
Building Envelope improvements (insulation, double glazing, reduction of infiltration).
Passive Solar Systems (External shading, daylighting components).
HVAC systems (improved controls and insulation, reduced hot water temperature, fuel substitution).
Ventilation (Natural ventilation, ceiling fans, solar chimneys, ground cooling, evaporative coolers).
Artificial lighting (indoor illumination levels, improved efficiency and control of indoor and outdoor lighting).
Other environmental design elements (other energy sources, microclimate improvement).
