Thermal Load-Based HVAC Design and Commissioning for Every Occupancy Type
HVAC system performance is determined at the design stage. Our HVAC practice begins every project with full heat load calculations to ASHRAE methodology, occupancy and fresh air analysis to ASHRAE 62.1, and energy performance modelling to BEE standards
Centralised Chilled Water Plant and Distribution
Chiller plant design and installation for large commercial, institutional, and industrial facilities, sized on verified cooling load calculations with energy efficiency as a primary design criterion.
- Air-cooled and water-cooled centrifugal, screw, and scroll chiller selection and specification
- Cooling tower selection, chemical water treatment, and Legionella management protocols
- Chilled water pump design: variable flow, pressure drop calculations, and pump selection
- Primary-secondary and variable primary chilled water distribution system design
- Chiller plant sequencing control, variable speed drive integration, and BMS supervisory control
- Thermal energy storage system design for peak demand reduction and energy cost management
Air Handling and Distribution Systems
Air handling system design for commercial, institutional, healthcare, and data centre environments, with airflow and ACH calculations performed for every occupied zone.
- Air Handling Unit specification and installation: direct drive and belt drive configurations
- Precision Air Conditioning units for data centre and server room environments to ASHRAE A2 envelope
- Air volume balancing and commissioning: TAB reports to ASHRAE 111 protocol
- Fan Coil Unit systems: two-pipe and four-pipe design with independent zone control
- Ductwork design and fabrication: GI rectangular and circular, acoustic ductwork, and flexible connections
- Mechanical ventilation design: fresh air, exhaust, transfer, and staircase pressurisation
Key Benefits
- All heat load calculations performed to ASHRAE methodology: cooling and heating load reports submitted before equipment procurement
- TAB reports submitted at commissioning in accordance with ASHRAE 111 standard
- Compliant with ASHRAE 55 thermal comfort, ASHRAE 62.1 ventilation rates, and BEE energy performance norms
- BMS-integrated HVAC enables remote fault detection, performance trending, and energy optimisation from day one
