Air leaks and heat loss in houses

The diagram gives information the way how air leaks into and out of the house, causing loss of heat and waste of energy. At first glance, it is important to note that due to the circulation of air which changes in several rooms, a considerable amount of heat and energy are lost and wasted.

In house, a great deal of air comes out through the ceiling on the first floor, followed by turning out into the space of roof. Air escapes through attic hatch on entrance in the middle room and also through two recessed lights which are located above kitchen and bathroom.

Moving to a more detailed analysis, entire of air into the house is from several parts. It comes through windows and doors into rooms in the house. Subsequently, it comes through the vents which have been installed in several part such as kitchen vent and dryer vent.

-I will help you to make any needed changes with your analysis of the diagram. I would first delete "the way" and replace it with "regarding". To make your analysis better, I would suggest describing in the next sentence how air seems to leak out of the upper rooms of the house.

-Place "the" before house. I'm confused by the air going out of the roof. You could possibly make it simple by describing how the air travels or goes out into the space of the roof. This sentence needs to be completely revised. Here is how you can change it:

"Then air escapes through the attic hatch when it enters in the middle room and also through two recessed lights, which are located above the kitchen and bathroom."

-In the next paragraph, the next sentence needs to be changed. Are you trying to describe the entire flow of air, including the air leaking in and out of the house?

-Revise part of the next sentence to read: "...windows, doors, and..." Change part of the next sentence to:"...parts such as the..."

You use 'which' after a comma. Change 'which' to 'that' for a direct emphasis.

//entire of air into the house is from several parts//

Entire? Do you mean entry ?
