Overview

We might sometimes experience a mismatch in the design room temperature and the temperature shown in the calculation table.

Method

This article shows how to fix the mismatch between the design temperature and max. temperature shown in the calculation table. In the image below, the design room condition for summer is at 23° Celsius, however, the results show the maximum room temperature at 20 degree Celsius.

This happens if there is a schedule assigned to the room temperatures. If the schedule contains a variation in temperature throughout the day as shown below, the calculation will show the maximum room temperature from the list.

The schedule here has its maximum temperature at 20° Celsius, hence the same is reflected in the calculation sheets.

To resolve this, we should create a new daily schedule which aligns its temperature with the max room temperature, and the same should be assigned to the project.

Note: This new daily schedule should be implemented into the weekly and yearly schedule as well. See below:

After assigning the new schedule, the results should match, aligned to the room temperature as required.

To resolve this, we should create a new daily schedule which should align its temperature with the max room temperature, and the same should be assigned to the project.

P.S: This new daily schedule should be implemented into the weekly ones and to the yearly schedule as well. See below:

After assigning the new schedule, the results would be fine, aligned to the room temperature as required.
