Thank you i do understand that concept and i wanted to test that by two different steps the first one was to increase the level of insulation for the wall and that actually reduced the cooling load not increased it i expected both would have a similar pattern.
Roof and wall insulation reduce cooling load by.
This is equally important for internal offices where the temperature is different to that of the main area.
It s the measure of heat resistance through a.
Heat from the outdoors is conducted through the roofing or wall materials as it enters the space.
To reduce conductive heat gain insulation in the roof or ceiling is most important.
Here are 3 ways you can reduce your building s cooling load this summer.
Small problems in your insulation can have a big impact on your cooling load.
The second step was to increase the area of the skylight on the roof to check if also that will decrease the cooling load but it.
In some southern areas more insulation is justified for cooling load avoidance than for winter heat loss.
Cavity wall and roof insulation will greatly reduce heat loss in these areas.
In most of north america wall and ceiling insulation levels optimized to reduce winter heat loss will be adequate for reducing summertime heat gain.
More expensive measures like double glazing need to be assessed for the energy savings they might bring compared to their initial cost and embodied energy.
If even a small section of insulation is missing the overall r value can decrease significantly.
Even if wall gains were fully 15 of the total cooling load bumping the performance of his r15 whole wall stackup to r17 produces less than a 2 reduction in the total load far less than what you d get out of cool roof shingles or even a high solar reflective index house paint.
The loads from the roofs and walls are conductive loads.
