Best Ways to Beat Mumbai’s Heat: Design Tips from Vatsal Vazir (Head of Design at CCI Projects)

The mercury is rising in Mumbai, and daytime temperatures are reaching record highs. Our air-conditioners are on overdrive and running non-stop. This is, unfortunately, making the rising temperature problem even worse.
Thankfully, CCI Project’s design team has been working on this for a while now. They have devised ways to bring down ambient temperatures within your home with the help of sustainable design hacks, state-of-the-art technology, and a few basic, economical swaps, all while being careful of environmental impact.
The Dual Exposure Advantage
Dual exposure refers to window placement on opposite sides of a room for enhanced natural ventilation. Here are two ways to use them to our advantage:
Keep windows open on both sides of the apartment between 6 am and 8:30 am, and after 7:30 pm to allow cooling, fresh breeze to flow through. This process is known to reduce ambient temperatures by 3-6°c on breezy days.
The science is simple - hot air rises and exits from one side, and in its place, cooler air rushes in from the opposite window.
The Fan Trick
A very easy, energy efficient way of managing internal room temperature is by using 2 standing fans. Place one standing fan facing outwards in one window to throw the hot ambient air out, and the other fan in front of the opposite window to draw cool outside air in. This amplifies the movement of fresh air by 200% and pushes cool breeze deeper into the room.
Simple Upgrades to Windows
Glass windows trap heat indoors and raise internal room temperature. Thankfully, modern technology and simple decor solutions can counter this. Here are 2 tried and tested measures:
Stick transparent high-SRI (Solar Reflective Index) films on windows to reduce temperatures inside the room. These nifty films can reflect almost 50-60% of solar heat, and are very effective in ensuring that the home stays cool.
Here’s how it works: The film reflects 50-70% of heat, which bounces back into the atmosphere.
It transmits 20-30% heat, which enters the room, and approximately 10-20% of the heat is absorbed and stays in the film layer.
Thus, this allows only a small percentage of the heat to enter the room, ensuring it is cooler than external temperatures.
Avoid thick, heavy curtains and instead opt for Honeycomb or Cellular shades. These trap air and create a dead air or insulating layer, which prevents the heat from transferring into the room. Most interestingly, though these prevent heat transfer, there is minimal loss of visible light.
Add Plants to Reduce the Temperature
Certain plants act as natural humidifiers, cooling the air that enters the home through a process called evapotranspiration, meaning they release water vapour from leaves creating a natural cooling effect. This works with plants with high water content like Areca Palms, Snake Plants, Spider Plants, Peace Lillies and Ferns, which need to be placed near balcony doors and windows for maximum effect. Studies have shown that these are effective in reducing ambient temperatures by 2-4°. Additionally, placing plants with thick foliage near glass windows has shown to block sunlight and reduce heat gain by 30-50% through the glass.
Some tasks raise ambient temperatures due to latent heat, such as heavy cooking, drying clothes in a dryer, using the dishwasher, and ironing clothes continuously for long periods of time. Try to reschedule the tasks in a way that they can be completed before 10 AM or when the sun begins to set.
Modern technology now offers many solutions that are more energy efficient, produce less heat and are economical enough to make the swap without making a dent on the wallet.
BLDC (Brushless DC) fans are more energy efficient and therefore generate less heat. The blade’s aerodynamic design creates more circulation and stronger air flow, translating to more air pushed per watt used, thereby cooling considerably more than previous generation AC fans with induction motors.
LED Bulbs
Traditional lighting solutions convert large amounts of electricity into heat.
Here’s a breakdown:
Conversion to Heat
Conversion to Light
90% of energy converts to heat
On the other hand, LED Bulbs convert 80-90% of the electricity into light, and generate only 10-20% heat. This is a drastic leap forward from previous sources, and can dramatically impact room temperature.
Windows for Cross Ventilation
Residences at Rivali Park 2 have been designed with dual exposure, that is windows on opposite sides of the room. Make the most of this by keeping windows open to allow the circulation of cool, fresh air.
Living on Higher Floors
If your residence is on the 40th floor and above, you have the advantage of higher wind speeds. Install invisible grills or a mesh, and keep your windows open at night to let the cool night air circulate throughout your home. Both these measures are great ways of ensuring that you can leave the windows open without worry, as they are child-proof and pet-safe.
At Rivali Park 2, we offer a number of shared amenities for residents to use. Instead of switching the air conditioner on at home, residents can use the library, tech-enabled spaces, or clubhouse, especially during peak hours between 2 pm and 5 pm. This saves resources and is such an environmentally conscious approach to living!
