solutions identified, such as reducing
internal gains and energy consumption
by installing more efficient lighting
systems, reducing cooling needs
by insulating the roof and installing
reflective coatings, and more.
An energy-integrated approach
for retrofitting is developed,
including architectural, functional
and technological solutions such
as modular multifunctional climate
adaptive façade system; ventilative
cooling; internal micro-layout design to
improve thermal zoning; solar reflective
coloured coatings; iBEMS (intelligent
Building Energy Management System);
green areas, integration of energy
distribution and refrigeration system
(HVAC+R), and more.
Next steps are crucial to implement the
retrofitting solution-sets and measure
the results. The assessment will be
done through energy simulations using
IME and cost-benefits assessment tools.
The implemented technologies will be
evaluated from a sustainable and social
point of view.
Before and after the retrofitting works,
