ABOUT US

TRANSFORMING THE WAY
YOU BREATHE

Jhonka is an engineering-led firm specializing in the design, execution, and long-term stewardship of healthy indoor environments. Moving beyond simple cooling, the company focuses on the ‘invisible layer of air’ to ensure CO₂ levels, humidity, and airflow are scientifically optimized for human health. Our 'Total Indoor Environment Design' philosophy integrates mechanical engineering with air quality science to deliver energy-efficient, sustainable outcomes. All this so that - You Live Better. Breathe Better.

Transforming the way you breathe

THE 6 STEPS FOR BETTER AIR

‹
›
STEP 1

Measure before acting

Jhonka begins by scientifically auditing the indoor environment to understand reality, not assumptions.

They measure:
  • CO₂ levels to assess ventilation adequacy
  • PM2.5 / PM10 to understand pollution load
  • Temperature and humidity behaviour
  • Odours, VOCs, and stagnation zones
  • Occupancy patterns and space usage

This creates a clear baseline of indoor air health and energy inefficiency.

STEP 2

Design air behaviour before selecting systems

Instead of starting with equipment, Jhonka designs in this order:

People → Air behaviour → Systems → Equipment → Controls → Data

They ensure:
  • Fresh air reaches the breathing zone
  • Ventilation is based on real occupancy
  • Cooling, filtration, humidity, and airflow work as one system
  • Energy efficiency is embedded at design stage
STEP 3

Optimise to balance health and energy

Fresh air normally increases energy consumption.

Jhonka avoids this through:
  • CO₂-based demand-controlled ventilation
  • Energy recovery from exhaust air
  • Hybrid and climate-appropriate system selection
  • Right-sized equipment to avoid overcooling
  • This allows fresh air without unnecessary energy loss.
STEP 4

Execute with clinical precision

During installation, design efficiency is protected through:

  • Clean duct handling and sealed air paths
  • Precision installation of HVAC, ventilation, and filtration systems
  • Acoustic and vibration control measures
  • Poor execution is avoided because it compromises air quality and energy performance.
STEP 5

Prove performance after installation

After execution, Jhonka validates outcomes through:

  • Testing, Adjusting and Balancing (TAB)
  • Airflow and ventilation rate verification
  • Pressure balancing and humidity checks
  • Sensor calibration and control logic testing
  • Clean air is measured and documented, not assumed.
STEP 6

Sustain performance over time

Indoor air quality is maintained through:

  • Continuous monitoring of CO₂, PM2.5, RH, VOCs
  • Data dashboards and trend analysis
  • Predictive, condition-based maintenance
  • Periodic indoor health and performance reports

This ensures air quality does not degrade after handover.
