The lighthouse project "MelEHR" at Melatengürtel in Cologne Ehrenfeld, which was completed in cooperation with Metropol Immobiliengruppe in spring 2021, is one of the most innovative projects of its kind.
This is a digital living concept consisting of 32 residential units, all of which are equipped with IoT and smart metering devices and can thus be operated entirely via smartphone. The project was created through the collaboration of Metropol Immobiliengruppe with BeyondBuild Expert GmbH and estateOS - the hardware was supplied by Berlin-based PropTech Sensorberg.
The digital living concept implemented here offers tenants several amenities that not only improve quality of life, but also raise awareness of sustainable behavior.
High security thanks to smart door lock
The use of a "smart door lock" is not only more convenient, as the door can be opened completely without a key, but also allows temporary access authorizations to be assigned. For example, friends, parcel delivery men or tradesmen can be allowed into the home by remote control. Access can be granted either via the app or an NFC card, and can then be revoked again. What's more, these electronic locking systems have a much higher security standard than conventional locks.
Never miss a parcel again with the intelligent parcel stations!
Who does not know it ? "Delivery between 10 and 15 o'clock" and then the parcel carrier arrives at 17 o'clock, when after waiting for five hours you have only been shopping for a short time. This problem is circumvented in the "MelEHR" with the intelligent parcel stations, which are installed in the entrance hall. They enable the messengers to store the parcels safely and without access by unauthorized persons when the recipient is absent. Afterwards, the tenant can simply open the respective parcel box via app and remove the parcel. This avoids the unnecessary trip to the nearest post office and, in the worst case, the loss of the package. In addition, returns can also be handled via the parcel stations or deliveries can be left for a neighbor.
Incentives for sustainable behavior through smart metering
The installed sensors for monitoring electricity, water and heat can not only provide incentives for cost reduction, but also lead to an improved awareness of sustainable behavior. This enables tenants to consciously contribute to reducing their own ecological footprint. The app provides an overview of the consumption data, from which it is easy to see how one is doing at any given time in terms of one's own monthly consumption targets.
In most apartment buildings, setting up an Internet or DSL plan is a chore at the beginning of every new lease. The contracts are usually inflexible and ordering and setting up the router takes a few days, so you often have to manage without WLAN for the first week. At MelEHR, however, there is a simple solution to this. Here, tenants have access to the pre-installed WLAN as soon as they move in, because the log-in data is stored in the tenant app. This means the user does not have to worry about setting up a contract and can start surfing right away. Internet access also expires automatically when the tenant leaves. The WLAN in the building is provided by NetCologne and ensures optimum network stability with a 300Mbit line that can be upgraded to up to 1000Mbit if required. Furthermore, the tenant has a very good WLAN connection not only in his own apartment, but in the entire house.
Always stay up to date with the digital tenant board!
Finally, there's an end to analog notices that no one reads or even notices. The digital tenant board is the collection point for all information about the building, management and tenant community - the digital "bulletin board" can be viewed at any time in the entrance area and in the MelEHR app and provides brief and concise information about the latest matters concerning your own apartment and the entire building.
With the digital doorbell feature of the tenant app, it is possible to operate the cameras at the front door at any time and then open it. This means that guests can be granted access to the entrance area or the apartment from the comfort of their sofa. In addition, the labeling of the doorbell system can also be changed via smartphone.
Networked Smart Home Devices
The term smart home encompasses any technology that makes the lives of residents more efficient or comfortable. MelEHR is also equipped with a network of intelligent smart home devices that are interconnected and can be controlled from a central point, the tenant app. For example, lights, blinds, air conditioning and heating, as well as the tenant's own components, can be controlled via the cell phone. In addition, voice control of these components is possible via Alexa or Apple Home Kit.
In the garage, which holds 22 parking spaces, there is the possibility to "charge" e-cars. Here, both company and private cars can be charged and the use of fuel cards is also possible.
The MelEHR also stands out positively when it comes to security. The smart lights mentioned above can be freely programmed so that if the tenant goes away, there is no sign of his absence. In addition, motion sensors, if the alarm has been armed by the resident, monitor any activity within the apartment and sound the alarm as soon as there are any irregularities. In addition, the windows also have sensors that respond to damage to the frame or glass and subsequently alert the tenant and the police.
