2. TARTU – THE
CITY OF GOOD
THOUGHTS
Facts to remember:
second largest city in Estonia (intellectual centre)
first mentioned in written sources in 1030
about 100 000 inhabitants
University of Tartu was established in 1632
paperless City Government since 2003
first in the world to introduce mobile parking in 2000Source: Gen Vagula
3. BACKGROUND
• Initiative „Smart cities and communities“
• 42 proposals were placed, 4 are funded
• Project period: Feb 2016 – July 2021
TARTU – the first and only city from Eastern Europe to carry out a
Smart City Lighthouse Project!
4. SmartEnCity - scope
3 sectors combined – energy, transport and ICT
Innovate, integrate, replicate!
Low-
energy
district
Sustainable
urban
mobility
Integrated
infra-
structures
Lighthouse
project
5. Main goal:
• the deployment of fancy technology
• energy efficiency, minimum energy
consumption
• increase in the quality of life
Make people happy!
Care about different
social groups!
70% of our inhabitants live in apartement
buildings
7. THE
CHALLENGE
Ambition: developing a model for
turning old Soviet apartment
buildings into smart
buildings and replicating
the solution elsewhere
Source: et.wikipedia.org
high number of quickly
deteriorating panel
buildings with an energy
consumption of
270 kWh/m2/year
8. Retrofitting of apartment buildings
Goals of SmartEnCity:
• retrofitting of 20 apartment buildings.
• decreasing the energy use from 270 kWh/m2/a down to 90kWh/m2/a.
Planned financing:
SmartEnCity – 1/3
National scheme – 1/3
Housing co-operatives – 1/3
9. • Decreased living costs (reduced
energy consumption)
• Increased comfortability, preferred
indoor climate, avoided health
problems: Smart Home Management,
need-based regulation of heating and
ventilation (fresh air)
• Reduced environmental footprint
(renewable energy, reduced energy
consumption)
• Increased life-time and value of real
estate
• Aesthetic appeal: art solutions
Renovation for People
11. SMART HOME
SOLUTIONS
Smart Home Management – energy use, indoor climate,
alarms etc
Sensors – movement, smoke, CO2-, air moisture,
temperature etc
Real-time information – situation at home; outdoor
climate; road conditions; city environment; availability of
rental cars and bicycles
12. New technical solutions need to be explained
- Automated regulation of apartment based ventilation (CO2 sensors);
- Solar (PV) panels for electricity production
- Smart home management system (wireless sensors)
- Building Information Modeling
13. May 10, 2016 CITIZEN
ENGAGEMENT
People and their will to be
opened for changes is the
key
Share information!
Involve!
Educate!
Motivate!
15. CITIZEN CENTERED
APPROACH
Social innovation model will be
developed and experimented on
the communities of renovated
buildings
A learning model based on smart
technologies, innovative business
models and ICT. How to motivate
people to change their
behaviour?
The concept of “learning from
those wiser”

17. Mobility for People
100% gas buses in public transport (2019)
Public EV fast chargers (2017)
EV Rentals: 2 cars + 4 bicycles in
each (2018)
Bike-sharing (2018)
18. Residual heat from district cooling system into district
heating system
Renewable energy for district cooling station: PV panels
and river water
Infrastructure for People
Street lighting with intelligent control systems (by 2017)
Over 300 new LED lamps
Movement detectors (some with cameras),
light reflection sensors, noise sensors and
environmental sensors (air pollution, temperature,
humidity etc)
Second biggest city in Estonia (i.e. the ‘intellectual centre’)
First mentioned in 1030
Population 100,000, total area 39 km2
Iconic places:
University of Tartu (since 1632)
Estonian University of Life Sciences
Tartu Science Park
Science Centre AHHAA
Supreme Court of Estonia
Ministry of Education and Research
In WW2, the city centre of Tartu was largely destroyed and under the Soviet housing scheme, the area was filled with panel buildings
Currently, there are 42 hrustsovkas with little aesthetic appeal and low construction quality in the city centre
The aim is to smarten up ca. 23 of these hrustsovkas as model smartovkas (ca. 900 apartments)
The pilot area includes ca. 3,500 people (58% women, 42% men)
20% of the residents are older than 65, 11% are younger than 14
New buildings are constructed in compliance with high contemporary (energy) standards anyways – the true challenge is how to retrofit the wealth of already existing panel buildings all over Europe
Ambition: developing a model for smartovkas in Tartu and replicating the integrated solution elsewhere
State-of-the-art building materials
Full thermal insulation
Windows/doors U-factor < 1
Indoor climate category II
Heat recovery ventilation
Heat regulation by each room
PV panels
Smart home sensors
Art competition for facades
= energy saving (class A), aesthetic appeal, high-quality living environment
Smart regulation – heating and ventilation parameters
Smart monitoring – feedback concerning energy consumption
Open data – basis for developing new and improved services
Sensors – movement and smoke sensors, gauges for measuring CO2 levels, air humidity and temperature etc.
Information at hand – conditions at home; weather, environment and traffic conditions, rental car and e-bike availability, communication with the housing association
