Here are some results, after one year of monitoring. In
the Barcelona building, 70% of the people working in the buil-
ding registered in the game platform, and interacted with the
game. The comfort conditions were maintained at a tempera-
ture of 12-22 ºC, humidity to 40-60%, CO2 kept at 1000-1200
ppm in 95% of the occupied area. About 80% of the people
declared to be satisfied with environment conditions – and a
net energy saving of some 12% was achieved.
In the Porto building, 75% of the people working in the
building registered in the game platform, and interacted with
the game. The comfort conditions were maintained at a tem-
perature of 12-22 ºC, humidity to 40-60%, CO2 kept at 1000-
1200 ppm in 95% of the occupied area. About 85% of the peo-
ple declared to be satisfied with environment conditions – and
a net energy saving of some 15% was achieved.
So, in this case, massive monitoring, intelligent mo-
dels and reinforcement learning through gamification helped
