Summary

With 18 years of experience in designing HVAC systems, I bring extensive knowledge and expertise to the field. Proficient in design software like HAP, HASS, and PIPENET, I have a proven track record in installing, testing, and commissioning HVAC systems and Central Plants. My expertise extends to obtaining local authorities' approval and QCDD Inspection. I specialize in designing energy-efficient and resilient HVAC systems for various sectors, including oil and gas industry facilities, hospitals, IT parks, metro stations, stadiums, museums, palaces, air bases, data centers, industrial complexes, and high-rise towers. I excel in performing HVAC Engineering Calculations such as cooling load calculations, pressure drop calculations, staircase pressurization, smoke extract calculations, car park ventilation calculations, pump head calculations, tunnel ventilation calculations, ducts and pipe sizing, system and plant sizing, and thermal energy storage sizing. Additionally, I am skilled in root cause analysis, value engineering, troubleshooting HVAC systems, as well as testing, adjusting, and balancing them. As a seasoned team leader, I have successfully managed design teams throughout my career. Furthermore, I am well-versed in sustainable design approaches based on LEED and GSAS requirements.
