3. Trends and facts
- BuildingAutomation Systems(BAS)is evolving into BuildingInternet of Things(BIoT)
- “Hotelswill lead the transition to smartbuildingtechnologies”(IHS Markit in2018)
•
•
•
•
Enhanced, personalised guest experience (connectivity, scenes,preferences, etc.)
Smarter hotel management and more efficient operation (housekeeping,disruptions)
Better energyefficiency
More efficient maintenance
Guestsare awayfrom their roomsmore than 50%of the time-
- In the US,a singleleaky toilet cancostasmuchas$840 ayear
- Energymanagementhasthe potential to reduceguestroomHVACusageby 20-45%
(Hotel Management Feb2017)

4. Connectedness:
-
-
Communications between building appliances & systems
Centralized management platform
Now enhanced even further with the emergence of aBuilding
Internet of Things(BioT), and smart grids and smart cities internet
clouds.
Efficiency:
- Intelligent connectivity platform allowing control of building systems
for optimal energy useand occupantcomfort.
Bigdata and data management systemsused today on urbanscale
canbe adapted to provide the highly precise monitoring and
management required by intelligent buildings.
