Ventilation related points to be taken into note during designing
stage.
Restaurant
z
The entrance door is difficult to open.

Hot outside air is coming in when the
entrance door is opened.
The restaurant has negative room pressure due
to insufficient supply air. When the entrance
door is opened, outside air enters into the
restaurant bringing warm air and pollutants.
Countermeasure plan
– Separate ventilation for kitchen and customer dining
area.
— Provide an air supply vent in the kitchen.
˜ Install a Heat Reclaim Ventilator on the dining area.
Office & Shoplot
z Ventilation cannot be achieved by
opening windows or doors.
z No large windows or doors at the area.
No air movement due to low airflow.
In the case of windows and doors are located at the front
only, there will be no air movement at the back of the
shop. Air will be stagnant and not well ventilated.
Countermeasure plan
Heat Reclaim Ventilator must be installed
to provide effective mechanical ventilation.
As a result, airflow is able to ventilate all areas of
the shop.
