Exactly, for such reasons I say houses and buildings in Pakistan are not properly designed and engineered.
There is some thing called HVAC design which no Architect consider. Almost all houses design does not have HVAC plans. In addition many more items.
Climateof Lahore, Islamabad and Karachi is different but design of windows is almost same.
When a housing society is laid out, town planner totally ignores the aspect of sun orientation.
Our houses are not properly sealed, hence heating and cooloing is leeked through closed doors and windows. I have never seen proper window for outer walls in Pakistan.
Since walls are made of clay they are inherintly insulators but there are cracks and unnccessary openings and pipings.
Almost every bedroom have toilet and bath room, all drain wholes in there are reasons for leakes.
Their has been some solutions above about improving roofs insulation. I dispute that in Pakistan houses ever have roofs.
Pakistani concept of roof is very strange. Normally, what is built in Pakistan is a load bearing ceiling made of concrete and iron. Perhaps the idea behind is to use it as terrace or load bearing for gardening resons.
Roof is some thing on top of the ceiling and in between exist a space / air which it self is a great insulator.
Now comming to the materials of roof their are variety of materials or roofings used, metal panels, clay tiles, steel frames, wood frames etc. etc. but those are generally not load bearing but does not need any further insulations, other wise you loose the look of the house, If I may say a home for some one.
Look is one parameter to be considered for choosing roofing materials and colours.
Why the hell we put so much load on the foundations unneccessary, is their no architect who understand this basic thing.
Do you know every mortar have a compressive strength and with less load we can save the cost in terms of structure materials.
But first we do not do things in proper manner than we start spending time and money to fix the short comings. |
