Academic Journal
The article compares the optimized variable air volume (VAV) and radiant cooling with dedicated outdoor air system (DOAS) heating, ventilation and air-conditioning (HVAC) systems installed in Software Development Block 1 (SDB-1) building of computer services company Infosys in Hyderabad, India. It discusses use of 34 percent less energy by radiant system compared to VAV system, lower cost of radiant system and improved thermal satisfaction with radiant system in comfort surveys.
