in Modena (IT). Working with these with local stakeholders directly involved
in the design and implementation of • The 1882 old market of 2.230m² in
the centre of Valladolid, ‘Mercado
del Val’, will be the first to reopen
after nearly a year and a half of
works. The focus on keeping its
natural essence was primordial.
After simulations and discussions
with the city architects, the chosen
technologies and solutions are now
installed. Comfort was improved
for shop-owners and visitors with
a multifunctional modular façade
now including glass windows to
let natural light enter and shutters
to regulate it. Geothermal heat
pumps are meeting the demand
for heating as well as cold and hot
water, while roof skylights provide
natural ventilation. A modern energy
management and monitoring
system (iBEMS) will allow an optimal
control of all technologies, taking
appropriate decisions to reduce
