Suggest ways in which heat that flows in or out of the house can be minimized.

There are multiple ways to minimize heat loss. Gaps around windows and doors are where heat escapes most frequently. You can seal any gaps using weatherstripping or caulk.

Another way to save energy is by replacing old windows. Older windows are frequently single paned. Adding storm panels can help tremendously. You can also replace the windows altogether and replace them with double paned windows, although this is very expensive.

In addition, many people hang blankets over doors that are not used regularly as well. This helps to keep the warm air in and cold air out.

A lot of air also escapes through the ceiling so it is not a bad idea to have the insulation in the attic checked as well.

Another idea is to plants trees and shrubs around the perimeter of the home. This will block some of the wind that blows in your house through spaces that are not very tight.

One of the biggest ways to minimize heat lose in a house is by having adequate insulation.  Most house building materials will minimize heat loss, but insulation products, available in several different forms, provide an especially effective barrier that retards heat transfer. 

Another area where home heat loss is significant is at the doors and windows.  One way to prevent heat loss in these areas is to have weather and caulking stripping properly installed. The addition of storm windows and doors aids in this as well.  Window treatment not only add an aesthetic appeal but assist in insulation also.

There are many different ways in which we can prevent transfer of heat across the interior of a house and its environment. All these methods aim to increase the insulation effect offered by walls, roof, doors and windows of the house.

Conduction of heat through walls can be reduced by making the wall thick, making them with material with high thermal insulation properties, or lining them with insulation material. It is also possible to increase thermal insulation effect by making leaving some hollow space within the wall or between wall and the insulating material.

Roofs can be made provide better insulation in the same way as walls. One specific mathod of providing better insulation is to use falce ceilings.

Doors and windows can also be made thicker and of better insulating material. Wherever glazed windows or other glazed structures are used, thermal insulation can be increased by using double walled glass.

It is possible to reduce extreme variations in temperatures parts of house by constructing underground chambers. These remain comparatively cool in summer, and warm in winters.

In addition to above methods, which are based on structural design of house, keeping the doors and windows closed also helps to prevent heat transfer.

Also if the objective is to prevent heating entering the house, rather than prevent both ways conduction of heat, additional measures can be adopted to prevent the effect of radiation heat. Some of these measures include, using light colour exterior paints, using blinds on windows, using reflecting glass and providing a net shade above the roof that reduces radiation reaching the roof, with minimum restriction of air circulation for cooling.

Ako looks to the ideal solution. You can try out many types of stuff like proper insultaion, installing auto lock doors and windows etc. I will help a lot.

black out curtains, closing windows, etc.
