Cooling Tower Make-up: Cycles of Concentration, Blowdown, Drift Loss

A 200 TR cooling tower in an Indian summer evaporates roughly 35 m³/day of water — most of it cooling the chiller condenser, the rest carried by drift and dust loading on the tower fill. Make-up water

Swimming Pool MEP: Filtration, Heating Load, Dehumidification & Make-up

A swimming pool is a hospitality amenity for users and an MEP integration challenge for designers. Filtration sets pump and pipe sizes; pool heating sets a substantial load on the boiler/heat-pump; de

Greywater Recycling System Design: NBC 2016 + LEED + IGBC Compliance

Greywater is the wastewater from baths, lavatories, kitchen sinks, and washing machines — distinguished from blackwater (toilet, urinal). It accounts for 50-80% of a building’s wastewater volume. With

Soak Pit & Recharge Pit Design: Sizing per IS 16636 + NBC for Site Stormwater

A soak pit absorbs storm water (and sometimes greywater) into the soil. A recharge pit recharges groundwater through deeper, larger-diameter design. Both serve as on-site stormwater disposal — require

Rainwater Drainage Pipe Sizing: IS 15797 + NBC 2016 + Storm Intensity Maps

A monsoon storm in Mumbai delivers 80-120 mm/hr peak intensity. Chennai’s North-East monsoon: 100-150 mm/hr peak. A roof drainage system designed for “average” rainfall ponds, overflows, and floods oc

Plumbing Vent Pipe Sizing: NBC 2016 + IPC 2018 + Loop / Wet Venting Strategies

A plumbing system without proper venting traps will siphon. Trap-seal loss = sewer gas in occupied spaces. The vent system pressurizes the drainage piping so siphonage cannot occur. Sizing the vent pi

Smoke Vent Design for Atria & Warehouses: Heat Release, Plume Mass Flow

A smoke vent at the highest point of a building creates the buoyancy-driven exhaust path that delays smoke layer descent. For atria and warehouses where mechanical exhaust is impractical or oversized,

Smoke Control to NFPA 92: Pressurization, Exhaust, Tenability for Indian Buildings

NFPA 92-2024 is the global benchmark for smoke control engineering. It governs three system types: stairwell pressurization, atrium smoke exhaust, and zoned smoke control. Each has its own performance

Hospital HVAC: NABH, FGI Guidelines, ASHRAE 170 Pressure Mapping (Pillar)

A hospital is the most demanding HVAC environment in commercial design. Multiple cleanliness levels, infection-control requirements, redundancy mandates, and patient-safety considerations all converge

Data Centre HVAC: Uptime Tier I–IV, ASHRAE TC 9.9, Hot Aisle / Cold Aisle (Pillar)

A data centre’s HVAC system has one job: keep IT equipment within manufacturer-specified thermal envelope, 24/7, with no failure window. ASHRAE TC 9.9 (Thermal Guidelines for Data Processing Environme
