This adjustment translates into measurable energy savings, Table 1b (below) illustrates the impact of the PVC strip
contributing to our goal of reducing electricity consumption installation.
by 20% and lowering our carbon footprint.
• Energy Consumption: A significant reduction in daily
electricity usage was observed, contributing to lower
operational costs and a smaller carbon footprint.
• Temperature Stability: The ability to maintain a consistent
indoor temperature has improved, enhancing comfort for
both staff and patrons.
• Operational Efficiency: The reduction in energy consumption
has indirectly boosted operational efficiency, with resources
being allocated more judiciously.
• Environmental Impact: Preliminary estimates indicate a
noteworthy decrease in carbon emissions, underscoring
the initiative's positive environmental implications.

Presentation of data
Table 1a (below) shows the temperature and aircon outflow
collected hourly over two days, before and after the Installation Explanation:
of the PVC strip curtain. • Average Daily Indoor Temperature: The Installation led
to a more stable indoor temperature, reducing the wide
fluctuations experienced before the curtain was in place.
• Peak Air Conditioning Outflow Loss: There was a significant
reduction in the percentage of cool air lost, indicating the
curtain's effectiveness in retaining conditioned air.
• Average Daily Electricity Consumption for Cooling: Post-
installation, there was a notable decrease in electricity
used for cooling, reflecting the reduced demand on the air
conditioning system.
• Operational Cost for Cooling: Lower electricity consumption
directly translates to cost savings in operational expenses
Explanation: related to cooling.
Temperature (°C): The temperature inside the kitchen area just • Carbon Footprint from Cooling: The reduction in electricity
past the door shows less fluctuation after the PVC strip curtain consumption for cooling also resulted in a lower carbon
installation, remaining more stable in the range of 22°C to footprint, aligning with sustainability goals.

indoor temperature post-installation.
Aircon Outflow (m³/h): Aircon outflow measures the volume
of cooled air lost to the outside per hour. After the curtain
installation, outflow losses are reduced by 20-30%, with a
typical pre-installation rate of 50–72 m³/h, compared to a
post-installation rate of 30–41 m³/h.
