This article reports cleanroom recovery time field validation across 5 Indian pharmaceutical facilities (Grade B + C cleanrooms; ISO 7-8 equivalent). Recovery time at standard 25 ACH = 9-12 minutes; at 40 ACH = 5-7 minutes; at 60 ACH = 3-5 minutes. Findings show ACH increase from…
This article reports CO₂-setpoint sensitivity in demand-controlled ventilation (DCV) systems across 8 Indian commercial offices over 12 months. Setpoints from 800 to 1,200 ppm tested; energy savings + occupant comfort surveyed. Results: 1,000 ppm setpoint achieves 22% OA-related …
This article quantifies the trade-off between sprinkler K-factor selection and pump head requirement + pipe size for OH-2 hazard Indian retail. Five K-factors (5.6, 8.0, 11.2, 14.0, 16.8 in US units) compared on a representative 1,500 m² retail mall design area. Higher K-factors …
This article simulates pressure cascade durability in a NABH-compliant operating theatre suite under realistic door-opening scenarios. CFD-based simulation of a 5-room cleanroom suite (Grade A OT, Grade B background, Grade C corridors, Grade D circulation) shows pressure cascade …
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…
This article reverse-engineers the ECBC 2017 trade-off compliance path for a 5,000 m² Indian commercial office to determine the maximum allowable Lighting Power Density (LPD) when other building elements (envelope, HVAC equipment, renewables) exceed prescriptive minimums. Analysi…
This article compares IGBC v3 and LEED v4.1 scoring outcomes on the same hypothetical 10,000 m² Bangalore office project. Identical design strategies (DOAS + ERV + free cooling + 200 kWp PV) yield 78 LEED points (Platinum threshold = 80) and 96 IGBC points (Platinum threshold = 7…
This article presents a field study of measured water consumption in six Indian commercial buildings (offices, hotel, hospital) over 12 months, comparing actual demand against NBC 2016 Pt 9 + CPHEEO Manual design assumptions. Results indicate measured demand is 25-40% lower than …
This article reports cv(RMSE) and NMBE calibration achievement for chiller plant energy models across five Indian climate zones using both Carrier HAP and OpenStudio + EnergyPlus. Twelve months of measured operating data from 5 commercial chiller plants (one per climate zone) is …
This article compares cooling-tower water-consumption modelling under IS 14661 and ASHRAE 90.1-2022 frameworks for typical Indian commercial chiller plants. A 1,000 TR reference plant in Mumbai climate is analyzed; water consumption is computed via both methods. Results indicate …
