Madrid multi-residential complex streamlines operations with mobile digital access

Virtual smartphone keys are convenient and secure for residents

Challenge

Business is booming in Spain’s build-to-rent (BTR) property sector: Investment grew over 17% between 2021 and 2022 alone*. Such high-profile success attracts more providers who compete for location, quality and customer satisfaction in the services they offer. The rental market also is tightly regulated, so time- and cost-efficiency in operations are essential.

STAY by Kronos is a fast-growing developer and service provider in the BTR market, with properties in cities including Córdoba and Tarragona. For a new twin-building site in Madrid, they sought convenient, user-friendly, connected access control for both homes and common areas including a gym and co-working space.

Key requirements

  • A solution to fit with their ethos which blends design, functionality, technology and sustainability
  • Access control which is convenient for residents and secures their home and common areas
  • A digital solution which makes it easy to manage service providers who require temporary access

Solution

STAY by Kronos chose a SMARTair wireless digital access solution. Building managers now quickly cancel any lost credentials and issue new ones — remotely if necessary — which reduces operating costs, maintains building security, and provides the flexibility they need. Secure, battery-powered i-max Wireless Escutcheons lock 121 apartments and shared amenities (gym, play area etc.) across two buildings. Main door entrances are unlocked via SMARTair Wall Readers. Residents access with a smart card, keyring or the SMARTair Openow app, which stores mobile keys on their personal smartphone.

For residents, the advantage over metal keys is a big plus: “They have the key virtually on their mobile phone, so we are sure they won’t lose it and they find it very useful,” says Carlos Rodríguez-Bailón Fernández.

No cabling and major door modification where needed during the installation.

Another benefit of the SMARTair i-max is easy locking by deadbolt projection: The SMARTair i-max has inbuilt features designed to enhance security and give residents extra peace of mind. It is easy for them to lock their front door by simply pushing its handle upwards activating the deadbolt projection with a secure 3-bolt lock. Similarly, the i-max antipanic mechanism guarantees quick emergency exit, even when the door is bolt-secured.

From a facilities perspective, SMARTair saves time managing the many providers who offer services to tenants. Programming temporary mobile access to common spaces like a dining boutique via TS1000 Web is fast and intuitive.

Thanks to its security benefits and resident satisfaction, SMARTair is now the standard solution for all STAY by Kronos projects — in Madrid, Tarragona and beyond.

"With ASSA ABLOY there was always that trust in an established company, a longtime leader in the market with a quality track record. They were also our technology ally.” Carlos Rodríguez-Bailón. Fernández, Managing Director at STAY by Kronos.
