Use Cases



Creating Positive Energy Districts with a Co-Creation Model

The co-creation model aims to enable cities, together with companies and other actors, to develop sustainable and smart districts of the future. It also aims to improve the transparency of the city planning process over its life span and increase communication between stakeholders.




Digital twin of Sello building block

The basic idea of the Digital twin of Sello building block is that it looks and behaves the same as real, but it is only a digital copy from energy point of view. The use case can be used for energy optimizing or Virtual Power Plant (VPP) use cases.



Simulating the city-wide charging demand

Based on available data, the usage patterns of the most common vehicle types have been modelled in order to estimate their energy consumption and parking locations. This has served as input to the modelling of charging demand at each location, assuming that all vehicles will one day be electrified.


Enabling E-bicycling through infrastructure

Enabling E-Bicycling is an innovative way to encourage sustainable mobility by charging and repairing bikes for free.



Connecting Elevators and Escalators to Smart Building Energy

Elevators and escalators communicate with the smart building energy management system in order to limit the peak power visible to the external electricity grid.


Behaviour Change through Mobile Probing with Citizens

Mobile probing enables studying citizens (mobility) behaviours in an interactive manner through their own eyes in real-time. This understanding builds a base for designing for successful behavioural change.


RES (Renewable Energy Solution) Integration

RES Integration aims to make the Lippulaiva in Espoo an energy positive district, through electricity and thermal energy systems.


Energy Storage

Thermal energy is stored in the ground (boreholes), in which excess thermal energy will be returned to and stored in the ground. Electric battery in Lippulaiva is used to optimize electricity usage and participating in electricity reserve markets.


Smart Energy Management

This use case aims to utilise predictive modelling and forecasting models to optimise energy sources.


Active Participation for Electricity Markets

Active Participation for Electricity Markets promotes producing own energy by optimizing electricity usage and taking actions in relevant reserve markets.


Engaging Youth: Buddy Class

Buddy Class is an interactive educational tool to engage local youth in the development of their own neighborhoods, in particular for energy systems and mobility.




Energy simulation assisted district planning

3D city models contain a lot of data about buildings. This information may be used to carry out building and block energy simulation and assess different improvement scenarios for achieving energy positiveness of city blocks. Visualization of results using concise indicators saves planners’ time.


SPARCS (Sustainable energy Positive & zero cARbon CommunitieS) offers products and services for these Smart City Solutions

Urban Air Quality Platform

Urban Air Quality Platforms centralise data from sensors or satellite imagery to provide city authorities and citizens with updated information on their urban environment's air quality.

Mobility Hubs

Mobility Hubs are places of connectivity where different modes of transportation - from walking to rapid transit – come together seamlessly.

Municipal Energy Saving Systems

The supply of energy to households, public buildings and services accounts for the majority of GHG emissions in the majority of municipalities. Energy Saving Systems represent punctual solutions to optimise energy consumption.

Peer to Peer Energy Trading

Peer-to-peer (P2P) energy trading creates an online marketplace where energy can be traded with low barriers. This makes local renewable energy more accessible.

District Heating & Cooling Systems

State-of-the-art district heating and cooling systems are paving the way for municipalities to reduce overall carbon emissions and to speed up the energy transition through the efficient distribution of heat and cold from renewable energy sources.

Energy Efficient Retrofitting of Buildings

Improving energy efficiency of the building stock in a city needs strategic and long-term thinking. Complex ownership structures, market barriers, diversity of building typologies, consumer preferences and multiple stakeholders involved makes energy efficient retrofitting a big challenge.

Bi-directional Electric Vehicle Charging

Bi-directional electric vehicle (EV) charging refers to EV chargers that allow not only for charging the battery of the EV but also for taking energy from the car battery and pushing it back to the grid when needed.

Digital Twin

Digital twins are virtual representations of an object, process or system that can be used to run simulations to optimise efficiency. Cities can use them to plan transportation systems, prepare for natural disasters, and identify optimal locations to install solar panels.

Energy Storage Systems

Energy storage systems are used to store energy that is currently available but not needed, for later use. The goal is to create a reliable and environmentally friendly system. As the share of renewables increases, so does the need for storage. With storage, energy can be used when it is needed.

Virtual Power Plant

VPPs are a response to the growing number of distributed energy resources (DER) making their way onto the grid, as VPPs allow their production to be pooled to achieve the flexibility and scale needed to trade in the electricity market; unleashing gains for prosumers, aggregators, and grid operators.

Smart Parking

A Smart Parking System makes use of sensors or other technologies to determine the availability of parking lots in cities. This information can be shared with drivers, reducing the time spent looking for parking, and thus reducing traffic congestion.

Vehicle Sharing System

Vehicle sharing systems allow customers to use various vehicles without the need to own each vehicle. There are different types of vehicle sharing systems on the market. Differences can include the type of vehicle shared, like car sharing, bike sharing, scooter sharing or electric vehicle sharing.

Local Energy System

Approximately one-quarter of the energy price is owed by the transportation of the energy. The implementation of a local energy system can shift the energy production from a centralised system to a decentralised system.

Electric Bus System

The Electric Bus System is a public transportation system that is operated by electric buses only. Electric buses are not only environmentally beneficial, as they do not have any local emission, but due to their longer lifespan and lower operational costs, they can also be financially beneficial.

Public Charging System for Electric Vehicles

The current EU regulation on emissions for cars is the strictest worldwide. Along with further restrictions the thresholds cannot be meet with conventional cars only anymore. One alternative technology, reducing the local emissions, are electric vehicles.

Building Energy Management System

According to the Energy Performance of Buildings Directive (EPBD), buildings are responsible for approximately 40% of energy consumption and 36% of CO2 emissions in the EU.

Bike Sharing System

A bike sharing system intends to provide a community with a shared fleet of bikes. Therefore, individual users do not have to own a bike, but rather everyone can use the fleet flexibly.

Smart Home System

The majority of public funding for energy efficiency within the EU is proposed in the building sector. The federal funds for energy efficiency in residential buildings added up to €97 million in 2019. A Smart Home System is one possibility to improve residential energy efficiency.

Urban Data Platform

Urban data platforms build the basis for a multitude of applications in a Smart City. An urban data platform intends to map, store and integrate data from different stakeholders of the Smart City ecosystem.

Smart Microgrids

Microgrids are emerging as an attractive, viable solution for cities, utilities, and firms to meet the energy needs of communities by leveraging more sustainable resources, while increasing resilience, reducing emissions, and achieving broader policy or corporate goals.
