Buildings nowadays
2
• Buildings as a group of many individual
technical subsystems
• None/weak coordination between
subsystems
• The building operation to maintain
comfort costs higher than it should

Buildings nowadays
2
• Many such non-cooridinated building
coincidentally produce large peaks and
sags of energy consumption on the grid
What if we can
orchestrate the
building subsystems
mutually and with the
grid ?

Idea behind 3Smart project
3
What if the grid assigns different energy costs to different times of
consumption and communicates it to the building in advance ?
If the grid and building subsystems are coordinated the building can adapt
to these prices by adjusting the consumptions of its subsystems to price
schedule while taking into account:
1. Users comfort demands
2. Weather and all other relevant predictions, e.g. occupancy schedule
3. Physical limitations of the system (available thermal power)
• Improved users comfort
• Lower operation costs
• Reduced energy losses
• Increased equipment lifetime

3Smart project – how we do it?
4
Coordination within building, within the grid and between the
building and the grid. How?
Anita Martinčević, M.Sc.
HUPG Conference 2018 - Sharing the future of cultural heritage5
• Every subsystem operated by its specific
submodule open for coordination with
other submodules
• Predictive control – the application takes
into account weather forecast, energy
prices forecast and all other relavant
predictions
• Mathematical optimizations – minimizing
operation cost of all submodules while
respecting comfort conditions
3Smart project – how we do it?
Anita Martinčević, M.Sc.
HUPG Conference 2018 - Sharing the future of cultural heritage5
3Smart project – how we do it?
When and how much energy to
insert into zone?
When and how to prepare
heating/cooling medium?
When and how much energy to
take from the grid, store or sell
energy ?

3Smart project and historical cities
• Urban areas subject to cultural heritage protection regulation
– strict regulations for infrastructural interventions
• 3Smart as a non-invasive solution
• relies on the existing automation system in buildings
• Configurable modules that can be adapted for the building at
hand regardless of the building configuration (installed
equipment)
Anita Martinčević, M.Sc.

Concerns?
7
1. Are we allowed to do it?
• if we can align with regulatory framework and remove
barriers - need to influence the regulatory framework
2. Can we make it economically viable?
• University of Zagreb
Faculty of electrical
engineering and
computing skyscraper
building (9th floor)
• Weather data from the
whole year 2014
• Commercial energy prices
(two tariffs)
