The Use Of Low Conductivity Window Frames

Provide Insulation on the Sunny side of the Roof and Walls

Insulation of the building has not received much attention in India. Air conditioning hotels and office buildings must be provided with insulated walls (hollow brick with insulation, walls with insulation, filling etc) to reduce the penetration of heat. The provision under the roof deck insulation is common practice.

The use of Doors, air conditioning, Curtains, PVC Curtains for air-Conditioned Premises Add hallways or the revolving door or self-closing doors of the primary exterior doors. Air conditioning, curtains and/or PVC curtains recommended for air-conditioned premises with intensive movement of people and trucks. Use intermediate door of slanted and vertical passages to minimize the building of the stack effect.

It is reported that the Biological Sciences Building at the Indian Institute of Technology, Kanpur, Roof and wall Insulation, reduce the cooling load on 23%. The window in the wall ratio is only 7%, and with double glass, insulated glass, reduce the cooling load another 9%.

Seven storey modern, air conditioning ed office building in Mumbai about 70,000 m2 has a heat load 185 summer. On the Windows and walls ratio is about 30%. Modelling has shown that the blocking of 50% from the window, laminated rigid insulation boards can reduce the air conditionng load on 13%. Provision of gymsum panels Alon g the wall with one-inch air gap can reduce the air conditioning load additional 4%.

Air conditioning system comprised 56 nos. air-cooled package air conditioners with an average efficiency of 2.7. Replacement of the air cooled condenser water cooler condenser can reduce the specific energy consumption..
