Banking Technology MNC Office in Chennai

The Building

In 2023-24, Indian subsidiary of Technology MNC was all set to finalize its large office in Chennai, India. The internet giant had signed a deal with one of the large Chennai based builder – DLF Downtown. tower strategically located in Tharamani, Chennai and offered tastefully designed office space. The building is certified LEED building and encompasses a total build up area of 0.85 Mn sqft, spread over GF + 9 floors.

The Need

The project’s large scale, combined with the desire for welcoming spaces within the overall framework, was a defining challenge for the design team. To make the most of the building’s glass facade and abundant natural light, the need of integrated lighting control and Solar Adaptive Motorized shades with daylight harvesting by drawing natural light deep into the space while mitigating heat gain and glare. Apart from use of standard strategies of lighting control, Solar Adaptive Motorized shades and seamless integration of VAV’s with lighting control sensors was required to save potentially large amount of energy. The system also needed to easily accommodate changes to layout and programming over time continuing to deliver cutting-edge performance for years to come. Wireless devices which could achieve this were desired.
Finally, the project had to be completed on time and budget, no small ask during a global manufacturing supply-chain.

The Solution

The Commercial Building LMS Controls Standards were prepared to provide performance based minimum guidance about design, installation and maintenance of Lighting controls systems installed to a BA Continuum India Private Limited. Chennai space which is controlled by a Lutron’s Lighting Management System (LMS).
Lutron’s Dali system digitally addressable dimming ballasts communicate with daylight sensors to automatically adjust electric lights and Motorized Blinds in response to available daylight. Occupancy/vacancy sensors and personal controls are installed throughout the space to ensure that lights are not left on when an area is vacant, but tenants still have control over the lights in their space. The occupancy sensors were seamlessly integrated with VAVs to minimize the time of closer (up to 90%) of VAV damper to save HVAC energy. Finally, a Lutron Athena Total Light Management system provides centralized control of all lights, shades and utilizes Athena Dashboard software to evaluate, monitor, and communicate energy use.

Commercial Building LMS Controls Standards

The control strategies are as follows, most of the strategies are self-explainable. Additionally, strategy of System integration included seamless BTL certified BACnet integration of Lutron’s native BACnet enabled processor with BMS (Building Management System). The main intent was to integrated the VAVs which controls the airflow to maintain the sensible load. However, VAV traditionally works on temperature function, which generally takes 10-20 mins time for damper to close to minimum set point. With integration with occupancy sensor, this time was reduced to sensor unoccupied status, conserving a relatively large amount of HVAC energy.

Area wise strategy:

The entire Workstation area Lighting is designed for Dali Lighting luminaires. When no occupancy is detected for 5 mins through Occupancy sensors, luminaires connected to the respective sensor footprints will be switched off. Luminaires in this area will automatically dim up & down based on the daylight availability through Daylight sensors. Shades will move UP and DOWN based on the movement of the sun and with some personalized master keypad control.

The area Lighting is designed for Dali Lighting luminaires. When no occupancy is detected for 5 mins through Occupancy sensors, luminaires connected to the respective sensor footprints will be switched off. Luminaires in this area can dimmed up & down based on the Scenes assigned through Wireless keypads.

4 PAX – 14 PAX ROOMS, LARGE CONFERENCE ROOMS, TECH TALK ROOMS (CLOSED ROOMS):

The area Lighting is designed for Dali Lighting luminaires. When no occupancy is detected for 5mins through Occupancy sensors, luminaires connected to the respective sensor footprints will be switched off. Luminaires in this area can dimmed up & down based on the Scenes assigned through Wireless keypads.

PODIUM, CAFETERIA, RECEPTION, SECURITY LOBBIES, SOCIAL HUB, CRECHE AREA, MICRO-KITCHEN, FITNESS STUDIO, FM OFFICE, CLINIC, MEDITATION ROOM, MUSIC ROOMS (CLOSED ROOMS):

The area Lighting is designed for Dali Lighting luminaires. When no occupancy is detected for 5mins through Occupancy sensors, luminaires connected to the respective sensor footprints will be switched off. Luminaires in this area can dimmed up & down based on the Scenes assigned through Wireless keypads.

Facade Area:

The peripheral area is with motorized blinds which will detect the amount of sunlight falling in the workspace and it will automatically lower the blinds. Rooms near façade side will have manual keypad control. Service, Support, and Success.

Beyond system design and installation, success depends on getting the right service and support. Lutron’s 65+ years of expertise and commitment to caring for the customer were critical to BA Continuum India Private Limited confidence in choosing Lutron for the project.

In addition, with the GUI, the BACI facilities team are able to monitor, measure and change settings on their own such as reducing the length of time-outs, without having to consult manufacturer. More important, though, is the reaction from the employees. One of the primary reasons for going with LCS is to provide the right environment for his workers. Occupant comfort is paramount to delivering the right environment. Lutron integrated LCS solutions automatically adjust to help create a vibrant, inspiring workspace while saving as much energy as possible.
