2020 KNX Award Asia Winner: Nobakht Offices Tehran

The Nobakht Building is a luxury commercial complex comprising six floors of offices and four underground floors of parking. It is located in Sohrevardi Street in the centre of Tehran, Iran and was completed in 2019. The client, Mr Nadimi, commissioned KNX experts Delham Tabesh to provide the automation system for the building. This project is the winner of the 2020 KNX Awards category for Asia.

The brief

The brief was to promote energy efficiency and occupant comfort. Every aspect of the building was to be made smart; including the ability of office workers to be able to enter their workspace without touching a single button.

Solution

We used KNX to integrate various functions including a weather station, cloud connection, DMX lighting, fan-coil control for heating and cooling, a media centre and conference room control, smart glass, public address system, lighting and presence sensors, access control, video entry system, parking management system, time attendant system, server room smart control, and several other features.

Our solution means that there is no need for an office user to touch even one button, since the facial recognition system automatically opens their office door. On entering, a presence detector is activated and the user is provided with their ideal comfort conditions. Using data from the weather station and light sensors, the HVAC, lighting and blinds are automatically adjusted to suit the user's preferred temperature and light levels, thus meeting the brief of providing comfort alongside energy efficiency.

Installation

From the start in 2016 to the finish in 2019, everything was dealt with by our technical team. We designed the wiring plan and installed and commissioned the devices, overcoming the particular challenge of integrating the access control and time attendance systems. Since commissioning the system, we noticed that the number of KNX devices which were requesting feedback on the KNX line caused heavy traffic on the KNX line, but we solved this by changing the cyclical time of measured data of the sensors and feedback.

Benefits of using KNX

For this project, we didn't only need a reliable system, but also one that can be easily interfaced with other systems, whilst maximising comfort and energy efficiency. KNX was therefore the obvious choice.
