CtrlS is a Tier-4 Datacenter in India, headquartered in Hyderabad. It deals with large group of networked computer servers typically used by various organizations for the remote storage, processing, or distribution of large amounts of data. Large groups of remote servers are networked to allow centralized data storage and online access to computer services or resources. CtrlS belongs to the IT industry

Client 

The project is a leading tier iv datacenters located in Mahape, Mumbai. ASHRAE Level 2 Audit was conducted as a part of USGBC O&M V4 Existing Building Certification. The Building Management System (BMS) is in place for the building.

Challenge 

During the audit, it is observed that Specific Energy Consumption of the chillers is at 0.59kW/TR, which states the chillers are performing at best efficiency. Check the flow rates of pumps form the vendor and run them near to rated data. Primary pumps, & Secondary pumps efficiencies are low compared to industry standards and hence the flow of the primary pump is far lower than the rated; even though the Delta T is maintained at 7 °C the chilled water outlet temperature is at 10.5°C, 10 8 °C. This higher chiller outlet temperature is primarily due to lower flow rate of primary pumps. .

Solution

Building automation consists of a computer-based system with measurement sensors and control devices for components such as HVAC equipment and lighting. This can provide important information on the performance of building systems if they are properly calibrated and maintained. Monitoring and controlling systems within a building allow building owners to track energy use and address areas of concern, providing opportunities for improved equipment efficiency. Monitoring ventilation helps maintain healthy indoor environments. Investing in a building automation system (BAS) helps ensure that equipment is performing as intended and significant energy savings can be realized.
