Facing trouble from heat? Ideas to cool down your house without Air Conditioner

Its summer, and that time of the year when the sun beats down on the rooftops. The increased Indian summer heat leads to rise in air conditioning and higher power bills. Kitchens are a particular vulnerability as they are non air conditioned, and the cooking heat adds to the discomfort.

house designed by Team, www.homedezine.inPresently, due to covid-19 and Work From Home (WFH) initiatives, people are staying at home longer, thereby usage of fans and air conditioners has increased during the daytime.

Reduce the heat of your building by 10-15% adopting these methods:

Heat resistant tile: This is a thermally insulated roofing tile for new construction and retrofitting. This tile can be laid using cement mortar or tile adhesive as the top layer on the terrace.

Brands: Johnson Endura, Rocotile Benefits:

  • It has high solar reflectance index (SRI) which will reduce indoor temperature. That leads to saving more energy required for cooling the rooms.

  • As a durable thermal insulated and high thermal resistant product, it lasts long. Also reduced requirements for replacements due to natural disasters, wind driven rain, moisture damage and vermin.

  • It is more economical on a life cycle and maintenance based product.

High SRI Paints: The concrete roof slab absorbs heat and transfers it indoors. What if you could make the slab reflect the heat instead of transmitting it? Brands: Berger, Beckers coating


  • Helps in reducing roof surface temperature of around 13-17 degree on a hot sunny

  • It can maximise total solar reflectance

  • Easy to use and bond with minimal surface preparation

  • Fast cure at room temperature

Turf : Grass as an aesthetic and insulating surface on terraces and roofs is trending nowadays.

Grass is available as mats, and this can be laid on a prepared soil based. Proper waterproofing and filter is recommended below the turf. It can also be laid on sloped roof. The grass and the soil underneath act as very good heat insulator.


  • Can be used in lighter roof construction

  • Saves about 15% of energy in a year

  • It increases the life of roof covering and also insulate the building.

  • More attractive than a regular floor treatment.

  • It will be extra if we add Roof garden or Garden to balcony which will help in cooling the air through vegetation and lead to reduce temperature of your house.

  • It looks more aesthetic and pleasant, creates a healthy and sustainable environment too.

Solar Panels: Sun light is a source of abundant and infinite energy.


  • Save electricity

  • Zero green house gas

  • Add value to your property

  • Low maintenance

Adequate Cross Ventilation: It is observed that if in the planning stage, a house is designed with proper cross ventilation, and keeping the sun and wind movements in mind, the house tends to be much cooler in summers, and warm in winters. These are the basic fundamentals of Vaastu design also.

Cool outside air is heavy, and therefore larger windows help to bring in more air. Similarly, air vents can be made in the highest point of the house (eg. staircase headroom) to let out hot air. If the building is designed for better air circulation, it will be cooler.
