• Concerns?

1



Buildings nowadays

2

Weather prediction

Building climate control

Storage system

Lighting

Controlable shading

Distribution grid

Central HVAC system

Microgrid

Energy market



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?


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





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 ?




MODULARITY

FLEXIBILTIY

REPLICABILITY

NON-INVASIVENESS



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)



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)
