Stadtinfo Köln (City Info Cologne) is a research project financed by the German Federal Ministry of Research that centres around the collection of various traffic data to be distributed to diverse platforms including the Internet, portable devices such as PDAs and mobile telephones, in-car navigation systems and variable message signs throughout the city. The project was implemented over a four-year period from 1998 to October 2002 by 15 partners in co-operation with the city of Cologne at a cost of €16.1 million.

The Cologne-based TÜV Rheinland headquarters is revitalizing its approximately 100,000 square meter business park with ten buildings in Poll. The management of TÜV Rheinland Immobiliengesellschaft mbH & Co. KG has developed an innovative concept with the engineering experts from Drees & Sommer as energy designer, building physicist and TGA planner: In future, there should only be one energy center. All buildings in the property are supplied with heat and cooling via the power grid of the new energy center. For heat supply, hybrid energy sources are used. These consist of the renewable raw material wood, a wood pellet boiler plant, as well as the fossil energy natural gas, gas condensing boilers and an integrated combined heat and power plant. The cold is generated by free-cooling, high-efficiency compression machines and absorption chillers. This can save 30 percent of primary energy compared to today. In addition, CO2 emissions will be reduced by more than 30 percent. The overall concept is modular in design and adaptable for the future.

KVB cycle hire Smart mobility   Smart mobility is climate-friendly, sustainable, space-saving and networked. It relies on diversity and multimodality. The resident of a smart city does not remain loyal to one mode of transport. The result is a mobility patchwork that is tailored to the individual circumstances and that can be configured quickly and easily at any time. Energy-efficient and space-saving mobility has priority here. "Sharing" is smart! The sharing of things and information already establishes itself under the term "sharing economy" and places the function before the property, in order to use existing resources more efficiently. Smart mobility in urban areas is therefore primarily a matter of sharing a networked mobility offer from buses, trains, bicycles and cars. Smart mobility is not just a technological task. Especially in the inner cities, walking and cycling will provide space for quality of life and urban development through active mobility. This is where the bicycle rental system of the Cologne Transport Company (KVB) comes in by closing a gap in the combination of environmentally conscious and mobility-active mobility. The bicycle rental system of KVB stands for an open architecture. It is therefore not a system with only fixed station terminals after the well-known role models from other major cities, because a template for all cases, the complex events of a city can consider insufficient. The system offers users fully flexible rental and return in the street, but also stationary station terminals depending on the available options and needs. The rental terminals cover the entire span between conventional stations and purely virtual stations.  

n times of energy transition and scarce resources, the architectural concept of Concrete Apartments Cologne is based on the requirements of the future - it is designed as an energy-saving passive house. This contains • a 26 cm thick external insulation made of rock wool, • triple glazed windows, • optimum recovery of radiated heat from residents and household appliances, • a ventilation system with a constant base temperature of 20 ° C - summer and winter - as well as • a digital control system that directs the use of luminaires and large consumers. Only those who like it even warmer must turn on the heating controller. All rooms are equipped with presence detectors, which automatically switch off lamps, for example, when not in use - this also saves energy. Of course, residents can also make the scheme manually. The energy and heat for the Boarding House creates its own, energy-efficient combined heat and power plant. State-of-the-art technology is also used here: surplus electricity is optionally fed into the public grid or used for the charging station for electric vehicles in the courtyard.

The diesel exhaust gases of the Rhine ships pollute the Cologne air with pollutants and fine dust and the climate with a significant amount of CO 2 . A part of it does not arise during the journey, but while the ships are at anchor. Because their generators must also run to generate the necessary electricity. Here, "Landstrom" provides a remedy: Since 2015, RheinEnergie has gradually been equipping a large part of the moorings along the Rhine with uniform power connections. Consequence: During the lay times the ship diesels can be turned off.

As well as energy-saving lighting, Smart Home is an important building block for an energy-efficient and comfortable future. With smart homes and smart meters in the network, homeowners and store owners can reduce their electricity and heating costs by an average of 7%! Add to that the great comfort of making the apartment burglar-proof and controlling almost every aspect of heating, electricity or security in the building. So you can control from your smartphone whether the stove is still on at home, a window has been left open, the heating is running at full speed or the light is on. In addition, before the house is on fire, modern, networked smoke detectors report any alarm directly to the owner's smartphone. It can automatically be initiated various steps, such. B. that the fire department is called. In order to test some scenarios and saving opportunities in everyday life and to make known the possibilities offered by these modern technologies, Smart Home applications were installed on the Klimastraße in nine private apartments of the Nippes Tower and in the bookstore Neusser Straße. This was financed by the project Klimastraße or the company RocketHome . In addition, it is planned to equip the entire climate road with smart meters from RheinEnergie.

Neusser Straße in the district of Nippes shows what a future SmartCity could look like, because a section of the street becomes Cologne's climatic road. There, the most important energy projects are implemented. All facets of climate protection are taken into account: from optimal building insulation and maximum heat efficiency to charging stations for electric vehicles and low-energy street lighting. Klimastraße offers innovative companies the opportunity to test their new products and services in everyday life. If possible, companies finance their projects themselves, promising projects are funded from the project budget of RheinEnergie AG. Companies also gain additional value by exchanging valuable information and innovative ideas with other companies, including at climate road events. For all the enthusiasm for innovation, of course, only technology is used that meets the very strict German safety requirements. In addition, RheinEnergie and the City of Cologne make sure that the high Cologne supply standards are adhered to. For all new projects, safety comes first - technically as well as logistically. That is why not everything changes in the climate route - but certainly much better. The following section deals in more detail with the individual projects.

The energy transition presents network operators and energy providers with particular challenges. Both have to deal with an increasing share of electricity from renewable sources in the electricity grid. Wind turbines and photovoltaic systems produce electricity, however, depending on the weather and therefore fluctuating. For a secure supply, it is necessary that electricity production and consumption are always balanced as much as possible. In order for this to succeed, utilities and network operators must always know where and in what quantity energy is generated and consumed. Only then can production and consumption be optimally coordinated. However, continuous metering is not possible with today's metering technology.The solution to the problem is smart metering. In the future, so-called "smart metering systems" will transfer consumption data to grid operators and energy providers. This ensures that they can optimally control the network at any time. The technology is mainly used in households and businesses with high annual consumption.Consumers can access the data at any time. The additional transparency helps them to further increase their energy efficiency and thereby reduce costs. New services provided by energy suppliers are intended to reinforce the positive effects.

In the framework of the project "Celsius" we investigate which method leads to the best possible results in order to increase the chances of realization. For this purpose, demonstration plants were built at three different locations in the city. In Cologne-Wahn and Cologne-Mülheim, the heat is extracted directly from the sewer using so-called gutter heat exchangers. The heat exchangers with a length of 60 and 120 meters are installed at the bottom of the canal. The heat transfer medium transports the heat from there to the heat pumps with a capacity of 150 or 200 kW in the boiler rooms of the schools supplied. In Cologne-Nippes, a total of three schools and a sports hall are supplied by sewage heat. Here, the wastewater is pumped through a newly laid, 400-meter-long bypass to the boiler room of the Edith Stein-.Realschule. There, in the largest direct evaporator in Germany (400 kW), heat is transferred directly to the heating circuit of the schools. With the three demonstration plants, an environmental relief of a total of 500 t CO2 / year is achieved. The use of wastewater heat is technically mature and well developed. Nevertheless, this form of waste heat utilization has so far been a niche existence. This is partly because it is still little known, often the necessary information is not available locally, their implementation is relatively complex and requires high investment. Further reducing these barriers is the goal of the Cologne CELSIUS project.  

District heating is one of the key pillars of our sustainable energy action plan. This plan has been decided by the local parliament in 2008 and renewed in 2015. Our first priority is to cut in half the total energy demand of the city until 2050 and then cover the rest with renewable energy and/or waste heat. To use large amounts of waste heat (e.g. from a waste incineration plant, industry, datacentres …) you need a distribution system, because it is not useable only locally. This is why we want to increase the share of district heating in the city. For the future we see a district heating system which will be “open source technology” – everyone can use the heat and also be a prosumer, delivering surplus energy, e.g. from a solar – thermal plant, to the system. There will not be any longer central DH-Stations but smaller plants and the use of all waste heat sources we can get.
