DOAS + Chilled Beam Energy Benefit Across Five Indian Climate Zones: Climate-Calibrated Quantification
This article quantifies energy benefit of DOAS + chilled beam architecture compared to conventional VAV system across five Indian climate zones (Hot-Humid, Hot-Dry, Composite, Mild, Cold) for a 5,000 m² reference office. OpenStudio + EnergyPlus simulations show DOAS + chilled bea… Read more →

DOAS + Chilled Beam Retrofit Case Study: Mixed-Air to Decoupled Latent at Chennai Luxury Hotel
The mixed-air AHU is the default Indian commercial HVAC architecture. In Chennai's warm-humid climate, it is also the worst-fit architecture for guestroom comfort, IAQ, and energy efficiency. This cas Read more →

DOAS Design for Indian Hot-Humid Climates: Decoupling Latent & Sensible (Pillar)
In a hot-humid Indian climate, the outdoor air load can be 50-70% latent (moisture). Traditional all-air HVAC systems handle both sensible and latent at the same coil — at deep dewpoint requirements ( Read more →
