So how will this new neighborhood differ from the others? The project of renovation is divided into six basic areas: ENERGY, TRANSPORT, PUBLIC SPACE AND GREENERY, PEOPLE AND THE COMMUNITY, DATA AND COMMUNICATIONS, SMART BUILDINGS and WASTES. Check the list of individual solutions that came from the initial research done by the Brno research institutes and that were inspired by other cities in Europe and around the world. This selection is not final yet – we expect that some solutions will appear during the planning proces and some of them will turn out to be ineffective. We want you to get involved so we will be happy if your share your ideas with us.

The future construction must be as efficient as possible from the point of view of energy in order to minimize the demands on the use of energy resources, thereby reducing the negative impacts of their use on the environment. In the Energy section, you will find measures that cover both the energy consumed for the running of buildings (heating, cooling, ventilation and hot water preparation) as well as for their electrical power supply.

Due to the large number of vehicles in the city, the road capacity is often utilised to the full extent. The number of problematic situations can be reduced by using an appropriate combination of modern vehicle identification methods and tools for the computer-based prediction of their movement. By using these tools it is possible to optimise vehicle motion control with respect to the achievement of the highest road passability. Intelligent traffic management is an indispensable part of the smart city concept. In the RE:Špitálka locality, we want to test measures such as the Internet of Things (IoT), big data technology, wireless sensor networks (WSN), mobile applications and similar.

RE:Špitálka will not only be inspired by nature, but it will be a place that works with natural processes and actively develops nature. Nature and the city are usually understood as opposites yet in RE:Špitálka they will work together. Nature will have an irreplaceable position here. The public space will be primarily possessed by people. It will encourage people to spend a substantial part of their leisure time here and not only serve as a space inside which we have to move between work, home or shops.

In RE:Špitálka there will be enough opportunities to get involved in community life. Projects such as community gardens, public workshops and share rental of things, etc. all belong to this section. Innovative forms of ownership of apartment buildings such as cooperative housing, baugruppe, etc. will be encouraged as well.

Nowadays, each housing unit needs access to several basic resources to provide the ideal home environment. These include: heat, electricity, water and gas. The trend of smart cities is to reduce energy use and strive for proper and efficient distribution to customers and households. Under the current flat-rate pricing model it is almost impossible to motivate households to manage consumption and save unnecessary resources . In order to motivate people to manage consumption there will be a newly created system that allows real-time consumption monitoring. Everything should work thanks to ICT technologies, use of mobile devices and server infrastructure, IoT sensors and sensors in buildings.

Re:Špitálka wants to support all major European trends concerning waste management. This is mainly related to the reduction of waste production (the ZERO Waste concept, the shared economy vision), sustainable waste management (waste management hierarchy) and the efficient collection and production of secondary raw materials.

The development of intelligent urban infrastructure is a never-ending process. The most important part of a Smart City is the existence and development of a large, robust and scalable infrastructure of information and communication technologies (ICT) that allows not only the interpretation and collection of large amounts of data but also the participatory part of the city management and administration. The second biggest challenge for a future smart district in terms of ICT is to ensure security and privacy.

MONITORING OF OPERATIONS AND SAFETYNESS BY DRONS

Description
Safety and traffic management must be handled in the Špitálka area. Nowadays, many systems can serve this purpose. Drone technology allows the device to send accurate GPS coordinates. Drones can autonomously make decisions in the areas of navigation and orientation in space. The device itself is then capable of carrying additional complementary sensors and cameras.

How does it work?

At the point of destination, the drone gets detailed and updated information through cameras or sensors and sends it to the central system database. The objective is to raise awareness of other parts of the system and reduce response time of the municipal police in urgent cases. There is also the possibility of involving drones in traffic management, where they will perform the function of detailed monitoring of traffic situations.

EFFICIENT USE OF RAINWATER

Description

Rainwater will be collected in tanks and subsequently reused for washing and flushing, the water collected in excess will then be soaked in at the site. In addition, it is possible to make the excess water create natural ponds in the locality, which will refresh their surroundings during hot months.

How does it work?

  • Rainwater infiltration: we always prefer rainwater infiltration at the place of the rainfall rather than draining it into the sewer. By infiltration, we restore groundwater and support evaporation to prevent drought. It is possible to do the infiltration by means of an infiltration groove, infiltration contour furrow or infiltration shaft.
  • Rainwater in the home: it is suitable for watering and cleaning, but also for flushing toilets and washing clothes. In addition, rainwater is more suitable for watering than tap water because it is low in salt and thus does not cause soil salinisation. Washing with rainwater is also beneficial. Rainwater is soft, so it dissolves detergents better, thereby reducing their consumption. Furthermore, the use of rainwater for washing does not give rise to the formation of  limescale. For rainwater that we want to use in the household, it is advisable to set up an underground tank with an overflow into the infiltration groove.

The city of Brno has already launched its support for this under two new grant programmes for the environment. One of them is the Nachytej dešťovku [Catch the Rainwater] programme, under which the city will support the use of rainwater.

More information about these programmes can found here.

GREEN ROOFS

Description

Roofs with classic coverings (asphalt, plastic, sheet metal, ceramic or concrete tiles) have the disadvantage that all the water that falls on them is usually drained directly into the sewer. Moreover, on hot summer days, these roofs become hot and raise the ambient temperature. A green roof, also called vegetation roof, on the other hand, is able to retain much water and cool down the surroundings by evaporating it.

How does it work?

In addition, a green roof consumes CO2, filters out harmful substances from the air and provides living space for plants and animals. A vertical garden may work the same way.

The City of Brno has already launched its support for this under two new grant programmes for the environment. One of them is the nationwide unique Zeleň střechám [Greenery for Roofs] supporting the creation of green roofs.

More information about this program can found here.

ELECTRICAL GRID

Description

An advanced power distribution network that allows controlling of power generation and consumption in real time. The network uses renewable energy sources (RES) and battery storage.

How does it work?

The price of electricity will change over time to reduce dependence on the main grid during periods of peak demand.

THERMAL GRID

Description

An intelligent system of connecting buildings with heat and cold supply.

How does it work?

This system will be based primarily on the use of geothermal heat and heat from sun-heated areas and its storage in underground storage, residual heat of buildings, use of renewable energy sources for additional heating or cooling of water, etc. This will ensure the lowest possible dependence on fossil resources.

MAKERSPACE

Description

Makerspace or open work shop is a creative space for modern DIY enthusiasts. The work shop is open to members and the public and is fully equipped for creative work, experimenting and manufacturing. Any handyman (maker), craftsman, student or entrepreneur can make anything they can think of here.

How does it work?

The purpose of the open workshop is to create a background with a variety of tools that you normally do not have at home. These include modern equipment and machines such as 3D printer, laser, CNC, electrical tools, sewing machines and various other devices. The open workshop will frequently organise a programme in the form of various courses for the general public.

SHARING STORE

Description

A sharing store can be best described as a library of things. It is basically a shop where you can borrow an item, tool or equipment you need for a certain period of time, and it is covered by the price of your membership.

How does it work?

Often these are things that lie in your basement, in the attic, or take up space in your wardrobe. These are objects that you may reach for once a year, for example, during a renovation, a holiday trip or a larger visit. Unless you have a spacious apartment or excess of money, you can take advantage of membership in the sharing store and cheaply borrow items such as a drill, climbing equipment, or board games.

One library of things already exists in Brno, you can find more information here.

INTELLIGENT LED STREET LIGHTS

Description

Lighting is specific in that it creates feelings of safety, overview of the location, a certain orientation. Therefore, sufficient light should always be provided. There are projects where, for example, public lighting is only illuminated by sensors when a person comes near to it, but this can also have a negative effect on the perception of people’s safety. These factors will be taken into account when specifying the lighting system for the future smart neighbourhood.

How does it work?

Energy-efficient LED illumination that will adjust its brightness based on the momentary need and intensity of natural light according to the data obtained from sensors. Where appropriate, lamps can be fitted with chargers for electric vehicles or with WiFi transmitters.

ENERGY MANAGEMENT AND OPTIMALIZATION OF ENERGY SYSTEMS

Description
Smart meters monitor energy supply and demand in public areas and all buildings in the area. These data are interconnected in a single energy management system that uses them to optimise energy flows between buildings and efficient use of energy resources (minimisation of load in peak periods, maximisation of renewable energy sources utilisation and reduction of energy losses). Energy management of buildings will be set up in such a way as to promote energy-responsible behavior of their users.
How does it work?
The buildings will be interconnected by energy flows, and energies between them will be directed on the basis of momentary and predicted consumption data. This means that during the day these flows will be directed primarily to office buildings and operations, while in the afternoon and during the night to residential buildings. This measure will make it possible to evenly distribute the network load and, reducing thus the overall energy consumption.
Optimisation of energy flows and their use will lead to cost savings both for building owners and for users alike.

BATTERY STORAGE AND OPTIMALISATION OF THE INTEGRATION OF NEAR-SITE RES

Description

Connection of renewable energy sources and onsite battery storages which can support demand from buildings and demand from electric vehicles. The inclusion of battery storage ensures that the maximum onsite usage of the renewable energy can be achieved, minimising any export to the national grid.  This will result in raising the value of the power generated by avoiding purchasing from the grid and exporting at a significantly lower value.

How does it work?

The development of control software and hardware will evaluate electricity market conditions and grid demand requirements, as well as potential oversupply from other renewables on the grid, and decide on how the battery is charged and discharged. Weather data will be used to monitor the probable level of generation coming from the renewables and thus affect the discharge rates to ensure that the required capacity is available for the following day.

VISUALIZATION AND 3D DISTRICT OPERATIONS MODEL

Description

Virtualization of the Špitálka district and 3D data model helps for research, pilots and other evaluations/analysis.

How does it work?

The application should provide space analysis, help in urbanization, support the predictive models, and provide space-time modeling opportunities for different kind of projects.

SMART PARKING SYSTEM

Description
A smart parking system that offers users parking options in the area, makes the booking of the parking place and makes it possible to use a mobile app to pay directly for the parking. Occupancy will be monitored in real time using a camera system.

How does it work?

If you choose a car to travel to the smart neighborhood, the application will offer you where you can park in the area and at what price. The price will depend on the time of day (increasing or decreasing demand for parking) and on the specific location. The application will offer you more possible parking options in your destination and at the same time it will offer you alternative options of how you can get to your destination (bike, public transport, etc.). It will book place chosen by you and you will be able to pay the parking fee directly through the application. The occupancy of the parking spaces will be monitored by means of a camera system, which will also ensure that it is up-to-date in real time.
Parking spaces for residents in the area will be located in the underground floors of residential buildings. This will reduce the obstruction of public spaces that can subsequently be used for more meaningful purposes.

SMART WASTE MANAGEMENT

Description

This solution’s objective is to lower the energy consumption of waste collection vehicles by monitoring their degree of filling and optimising the route of the collection trucks.

How does it work?

Sensors will be installed at waste facilities to measure the filling percentage and indicate when the container has reached its maximum fill level – or when it has been emptied. Data will be communicated through a network to a centralised management system.

VACCUUM SYSTEM FOR MUNICIPAL WASTE COLLECTION

Description
This modern and sophisticated waste collection system is implemented in newly built neighbourhoods in Europe and Asia.

How does it work?

It allows doing the waste collection less frequently, it is possible to transport the waste fractions more efficiently through waste compaction and there is no need to provide suitable routes for large garbage collection trucks. An obvious disadvantage is represented by high initial costs of introducing the system into existing buildings and locations.
This is just one of the ways in which waste collection can be approached. Together with other options, the vacuum system for municipal waste collection will be further assessed and evaluated.

ENERGY STANDARD FOR NEW BUILDINGS

Description
The European Energy Performance of Buildings Directive (EPBD) introduces requirements to reduce primary energy consumption in buildings. From 1 January 2020 on, this Directive requires that all new building project documentation comply with the requirement for so-called near-zero energy buildings.

How does it work?

A near-zero energy building is a very low-energy building, the consumption of which is largely covered by renewable sources.
Buildings designed in the so-called passive standard go even further in the energy efficiency requirements, where their demands for total energy consumption are even lower than for buildings with almost zero consumption. Buildings that, moreover, produce more energy from renewable sources (for example, through photovoltaic panels) than they can consume are called energy plus houses. In the case of entire neighbourhoods built in such a standard, the term Positive Energy Districts (known as PEDs) has become widely used.
The construction of the RE: Špitálka smart district is expected to be conducted in a passive standard. Possibilities of construction of energy plus houses will also be verified.

INTELLIGENT BUILDING CONTROL AND END USER INVOLVEMENT

Description

An energy management system for public buildings that enables continuous monitoring and analysis of the indoor environment and thus an efficient setting of energy flows. Depending on parameters such as the presence of people (and their number) in a room, sunshine, outer temperature, room utilisation prediction and others, the system can set optimum regulation of the temperature and inner climate in buildings.

How does it work?

The energy necessary for heating / cooling and ventilation of the rooms will be supplied based on measuring of relevant parameters affecting the temperature in the building (and in the rooms themselves). In the case there is sufficient sunlight, it will be possible to reduce the energy needed to heat the rooms that are directly affected by it. As the outer temperature gradually increases, heating can also be reduced in the rooms on the northern side of the building, etc. By measuring the carbon dioxide content in the rooms, it is possible to calculate how many people are present in the building and in each room. This provides valuable information on how well we are doing in using these premises. If a longer absence of people in a room is detected, the lights will be turned off and other devices will also be switched into the power saving mode.
By measuring the energy consumption for heating, cooling and ventilation in the building and in the individual rooms, it is possible to trace whether there are any major differences between the rooms and subsequently figure out their reasons.

COLLECTIVE HOUSING MODELS

Description
Collective housing models such as community land funds, housing associations, cooperative homes, Baugruppen and others have already been tested with great success in various cities and by different population groups. Therefore, participatory housing is a great opportunity for new housing construction in Brno.

How does it work?

In many areas of Brno, there is space and potential for projects such as Baugruppe housing or housing with low environmental impact, or, as the case may be, shared social housing. The area of the Špitálka district has a particularly great potential and can be a model example for various forms of housing. Sharing costs and models of collective ownership or financing can be a big help in transformation.

TRAFFIC INTENSITY DATA

Description
Installation of cameras / sensors to detect the movement of persons, cars, bicycles and other objects in public space. Automatic counting of traffic intensities in various transport modes is no longer a problem for camera systems.

How does it work?

These data can be subsequently used to identify and eliminate troublesome spots, adapt public space or navigate drivers to vacant parking spaces. In the future, they can be linked to the city data portal. When this data are collected, the data will be automatically anonymised and aggregated, making it impossible to distinguish the movement of person at the level of individuals. This will ensure the right to privacy protection.

URBAN GARDENING

Description
Urban gardening or urban farms, known in the Czech context as “komunitní zahrada” [community garden], the basic idea of which is an active use of abandoned areas in the centre of the city, transformation of appearance and revitalisation of urban neighbourhoods. Not only does this form of land use encourage local production, because people can grow vegetables, fruit or herbs, but it also strengthens human relationships.

How does it work?

Gardening is an activity that can be participated in by people of all ages and can provide amusement to senior citizens, mothers with children, but also people who spend the whole day in the office. The Urban Farms concept can be implemented in several ways in the Špitálka area. One of them is the use of green spaces as gardens. This would allow people from the neighbourhood to have active relax near their homes. Gardens could also be part of the common areas of the collective housing project .
