HVAC Treats Buildings as Zones. Biothermal Treats People as Individuals.PREVIEW

Central HVAC systems often run at 20°C to
22°C. People sitting for 8 hours in cold
air catch more respiratory infections,
report more muscle tension, and are sick
more often. The building is slowly making
people ill.

Occupants in over-cooled buildings report
higher rates of upper respiratory
infections, muscle stiffness, and general
malaise. Research on thermal discomfort
shows that peripheral vasoconstriction
(blood vessel narrowing in the skin in
response to cold) reduces immune response
in the mucous membranes lining the nose
and throat. People in chronically
over-cooled buildings have lower mucosal
immunity and catch colds more easily.

Muscle tension accumulates in cold
environments. Sustained sitting at low
operative temperature (below the
occupant's comfort setpoint) triggers
postural muscle tension, particularly in
the neck and shoulders. Over weeks and
months, this becomes chronic muscle
tension, headaches, and referred pain.
Employees report more sick days.
Productivity drops 3 to 5 percent.
Facilities teams respond by lowering the
thermostat further because they believe
the building is too warm. It is not. It is
too cold.

Central thermostats set to ASHRAE 55
specifications, which assume
non-acclimatised comfort, force Indian
office workers to sit in temperatures
below their adaptive comfort zone for 8
hours daily. March through November. Nine
months of low-level thermal stress creates
cumulative health effects. Higher
absenteeism. Lower engagement. Reduced
retention.

Biothermal Microconditioning eliminates
forced over-cooling. Areca palm clusters
provide temperature buffering, allowing
central HVAC to run at slightly higher
setpoints without occupants reporting
inadequate cooling. Evapotranspiration
from plant canopies increases air
humidity, protecting mucous membranes.
Local shade and airflow prevent the
thermal shock that triggers sustained
vasoconstriction. One day deployment. Sick
days drop. Comfort returns.
