MBRDI CASE ST UDY

Firm on its mission to nurture excellence, MBRDI dedicated a whole
floor of this facility to Learning & Development and aptly called it"Gurukul". Comprising of training rooms, meeting rooms, quiet
areas and even in-house banquet halls, Gurukul's design and build
prioritizes occupant needs and experience. MBRDI was seeking an
automation solution that would enhance their occupant's experience
further - a system that improves thermal (temperature and air
quality) and visual (lighting) comfort, provides tailored occupant
experiences and empowers the facilities team with visibility intotheir energy consumption and HVAC & Lighting systems as well as
remote management capabilities. All this while making saving energyand improving the facility's carbon footprint!

THE 75F SOLUTION
MBRDI conducted a thorough assessment of 75F's solution, comparing it tosome of the most prominent players in the industry. 75F stood out from thepack as the only player that offers a vertically integrated solution (Hardware+ Software + UI + Data Analytics + Services) and for providing unified HVAC,IBMS & Lighting Control & Automation capabilities. MBRDI also found 75F tobe a better fit, both in terms of value and capabilities. Even finer details, suchas 75F's aesthetically designed sensors that complement the facility's design
and the intuitive graphic user interface that serves up insights and analytics
to the FM team, contributed to 75F winning this project.
75F built a highly customized solution for MBRDI working closely with
MBRDI's Project Management Consultants, Architects, Electrical Consultantsand HVAC Design Consultants. Smart sensors were installed across the site,
to collect real-time inputs for temperature, humidity, VOCs, CO2, movement,sound levels, LUX levels and even occupancy count for each zone. Withmillions of data points processed daily, 75F applies machine learning topredict daily challenges and proactively control HVAC and lighting systems for
optimum comfort and efficiency.

HVAC Automation and Control
75F installed its award-winning Dynamic Airflow Balancing System and Dynamic
Chilled Water System, providing comprehensive integration between the highside & the low-side and ensuring greater comfort and more efficient operations.
Depending on the thermal, airflow and humidity requirements in each zone,
the system proactively controls the chilled water flow rate, ramps up/down theVFDs for fan motors, turns on/off the AHUs and modulates the Smart Dampers
installed across the site. Thereby, 75F creates a continuous dialogue between
multiple HVAC units in the facility and ensures they work together to reduceenergy usage and deliver even temperatures throughout.
Additionally, 75F's system is also integrated with Mitsubishi VRFs at the site. 75F
Smart Nodes communicate with the VRF indoor unit & turn it on/off based on
setpoint temperatures, occupant preferences and schedules.

75F automates and controls the AHUs, VRF, TFAs, Chilled Water System, and schedule & dimming of lights,
creating a continuous dialogue between the systems and optimising efficiencies.

Indoor Air Quality Management
The 75F® Smart Stat™, installed in all the training rooms, has 7-onboard sensors
that collect real-time data about various parameters including VOCs and CO2
concentration. If the CO2 concentration approaches threshold limits, the 75F
system automatically modulates the Treated Fresh Air Units (TFAs) to push in
more fresh air. These TFAs are also auto-scheduled to run on an hourly basis
to keep fresh air circulating in the facility. The system also provides the facility
manager with insights on CO2 build up and relevant trends for pre-emptiveaction. It also proactively sends alerts if the VOCs are higher in an area.
Lighting Automation & Control
75F's system automates lighting in the facility based on real-time factors such as
weather forecasts, occupancy, scheduling, user preferences, etc. 75F installed
motion sensors across the facility so lights turn on/off automatically based on
occupancy, saving energy and time. Daylight harvesting in areas which get direct
sunlight offset the amount of energy needed to artificially light the space. TheLED lights automatically dim or brighten as per the sunlight, making sure optimal
lux levels are maintained.

running on tablets deployed in each training room. Occupants can now adjustthe temperature and dim/brighten or switch on/off different lights at any
given moment using the app. If during a training, the first row of lights need
to be turned off, second row to be dimmed and third to remain bright, thenthe occupants can do this themselves using the Occupant App. They can alsoschedule changes to the temperature and lighting. The facility is in effect “switchless” as the capability to control and monitor is provided through the App.
Energy Management
75F Facilisight provides the facility team with remote management capabilities
along with visibility and insights into HVAC and Lighting energy consumption.
From heatmaps and occupancy maps to trends, analysis and granular reporting- the facility team at MBRDI gets a single pane view of the entire facility. These
insights and analytics are served up in an intuitive graphic user interface allowing
the facility team to monitor and proactively manage the facility, adding efficiency
and value for their occupants.
Besides automatically monitoring, managing and controlling these systems
proactively, 75F also provides the FM power to control their buildings at a click
anytime, anywhere.

Occupants are provided with an Occupant App and Intelligent Temperature Mote™ (ITM) sensors ineach room for superior temperature and lighting control

Occupant Control & Feedback
One of the unique features of 75F’s solution at MBRDI is the 'Occupant App'MBRDI facility team can remotely adjust and schedule temperatures and lights and the health of the system can bemonitored to ensure maximum efficiency

THE RESULTS
75F's innovative system has brought incredible efficiency to MBRDI. With
75F system in place, the facility has been recording 25% savings on HVAC
and lighting energy each month. Moreover, occupants enjoy a better work
environment and increased productivity thanks to comfortable temperatures,
improved air quality and better lighting.
Occupants of the facility are empowered to tailor their zones for temperatureand lighting, allowing for precise comfort at all times. Features such asscheduling, daylight harvesting and occupancy-based control have made thefacility 'switch-free' and intuitive, resulting in better occupant experience.

complaints and is able to deploy those resources to other important tasks. They
have also noticed a marked improvement in their operational efficiencies; as aresult of quick Installation, zero downtime and no on-site IT infrastructure andmaintenance costs. Facilisight has provided theteam with insight and control over the HVAC & lighting system in the facility.
They are now able to monitor and control energy usage in real-time remotely.
75F's self-optimising, intuitive system echoes the same principles that MBRDI
holds close: innovation, excellence and comfort. MBRDI set out with great plans
for their new state-of-the-art R&D centre and 75F took it to the next level with
its unified HVAC, lighting, iBMS, automation and energy management system.

The facilities team at MBRDI now spends lesser time responding to occupant
