Cooling Of A Building

Question 1

What is thermal conductivity

Answer 1

Thé higher the thermal
Of a material the higher the rate of energy transfer by conduction across the material

Question 2

Answer 2

High

Question 3

What is the thermal conductivity of double glazed windows

Answer 3

Low because less thermal activity

Question 4

Answer 4

Via roof or windows

Question 5

What does low thermal conductivity do

Answer 5

Reduce the rate of which thermal energy passes through it

Question 6
