Objective:<\/h5>\n\n\n\n

Demonstrating excessive heat exhaust from air conditioners by comparing time required for the evaporation of ice.<\/p>\n\n\n\n

Outcome:<\/h5>\n\n\n\n

Students will realise that our urban \u2018Thermal-excess-comfort\u2019 is causing great discomfort to all the invisible, silenced, excluded, marginalised and is a major contributor for GHG emissions in turn causing climate change.<\/p>\n\n\n\n

Requirements:<\/h5>\n\n\n\n

Working AC\u2019s in the college building, 2 boxes with ice cubes, stop watch<\/p>\n\n\n\n

Prerequisites:<\/h5>\n\n\n\n

None<\/p>\n\n\n\n

Procedure:<\/h5>\n\n\n\n

Step 1: <\/em><\/strong>Switch on the AC\u2019s of one of the spaces within the college building. <\/p>\n\n\n\n

Step 2: <\/em><\/strong>Gather students in the vicinity of outdoor units of the AC\u2019s, during noon around 12 pm (peak or mid summer).<\/p>\n\n\n\n

Step 3: <\/em><\/strong>Form two groups within the students – ask one group to stay next to the exhaust of the outdoor unit with one box of Ice cube and another to stay next to a window without any AC, on the same side of the wall with another box of Ice cube placed on the window sill. <\/p>\n\n\n\n

Step 4: <\/em><\/strong>Note down the time during the beginning of the demonstration<\/p>\n\n\n\n

Step 5: <\/em><\/strong>Ice will begin to melt eventually. Note down the time once ice has completely evaporated.<\/p>\n\n\n\n

Step 6: <\/em><\/strong>Record the readings in the tabular column.<\/p>\n\n\n\n

Step 7: <\/em><\/strong>Introspect and discuss around the following:<\/p>\n\n\n\n

    \n
  • Imagine the amount of heat and gases that might be thrown out of the tremendous amount of ACs that are used currently.<\/li>\n\n\n\n
  • Is there any change in the temperature of air that is passing through the window without any AC due to the ice box placed on the sill through Evaporative cooling principle?<\/li>\n\n\n\n
  • How can we as Architects be more mindful and design spaces without AC as a requirement or minimal Active cooling requirement?<\/li>\n<\/ul>\n\n\n\n
