Just after heat shock comes electricity bill shock

Extreme weather, shocked to see electricity bill

According to information from the Ho Chi Minh City Power System Control Center, in early May, Ho Chi Minh City broke its record for electricity consumption with 94,802,677 kWh/day, surpassing the highest level in 2022 by nearly 2.8 million kWh. In addition, Ho Chi Minh City Power Corporation also said that even on weekends when the production sector and agencies and office buildings are closed, the amount of electricity consumed is still higher than the record of previous years. In Hanoi , on hot days up to 40-44 degrees Celsius, the amount of electricity consumed also peaked.

Although extreme weather plays a big role in skyrocketing electricity bills, people's passivity in heat-fighting solutions is also a contributing factor. Specifically, people often wait until the hot season to start fighting the heat with quick "cooling" devices such as water fans, steam fans, air conditioners, etc. The effectiveness of this method is only temporary, creating an additional burden on monthly electricity bills.

High electricity consumption costs due to "hiding from the heat" with air conditioners and fans are causing many households to worry.

Specifically, when the outside temperature is 40 degrees Celsius, if the room air conditioner temperature is set at 20 degrees Celsius, the electricity consumption after 8 hours of a 1HP air conditioner is 10.72 kWh. For the same period of use, if compared to days with an average temperature of 30 degrees Celsius, this electricity consumption is 4-5 times higher.

Instead of using passive solutions, people can implement active heat-resistant solutions for living spaces, especially in the roof, terrace and exterior walls of the house. This is a sustainable solution to prevent thermal shock and electricity bill shock.

How to get through the harsh summer, unpredictable sunshine and rain

Specifically, in the case of completed projects that "accidentally" skip the heat-proofing step during construction, homeowners can use heat-proof paints to cover the old paint surface on the exterior walls and roof to "urgently" cool down the house. According to experts, Sikalastic®-590 and Sika® RainTite of the Sika brand are one of the most exclusive and effective "2-in-1" heat-proofing - waterproofing solutions at the present time.

In particular, Sikalastic®-590 is recommended for the roof deck thanks to its ability to withstand the harsh and hot weather typical of Vietnam. The special structure in the product helps prevent heat transfer and light reflection, thereby reducing the temperature of the painted surface, reducing heat absorption into the space used. Depending on the outside temperature, construction method and roof material, Sikalastic®-590 can help reduce heat absorption by 5 - 10 degrees Celsius, saving electricity from air conditioning. Another plus point of Sikalastic®-590 has good crack coverage ability, prevents staining and weathering, ensuring aesthetics for the project.

As for exterior walls, common building materials such as bricks are not good at heat resistance. Therefore, Sika® RainTite is considered a "savior" thanks to the application of heat radiation reflection technology that can reflect UV rays, helping to reduce wall temperature by up to 10 degrees Celsius compared to conventional paints or waterproofing agents. In addition, Sika® RainTite is also used for waterproofing and heat resistance for many other surfaces such as vertical walls in houses, concrete roof floors, roof baseboards and finishing surfaces.

Sika's "2 in 1" waterproofing and heat-resistant solution duo

Not only is it an indirect solution to "reduce electricity bills", Sikalastic®-590 and Sika® RainTite also limit the risk of overload, circuit breaker tripping, and even fire and explosion in household electricity use. The heat-resistant duo also has a VOC content that complies with requirements, has little impact on the environment, and is safe for construction workers and users, so it is also considered an indirect solution to protect the living environment.

"However, instead of waiting until the water reaches your feet to jump, proactively preventing heat from the structural design stage and heat-resistant system before building the house is still the optimal solution. Don't wait until the hot season comes to struggle to find a solution," Sika experts advise.

Sika provides comprehensive solutions for construction and waterproofing of townhouses.

For example, initial planning options such as arranging rooftop gardens, planting climbing plants on walls, increasing the area of ​​gardens and water surfaces, etc. will help reduce the emissivity of the building's surface, preventing heat on an overall scale. Or the homeowner should study how to design courtyards and skylights to increase air convection, leading hot air masses to escape up and out, making room for lower heat air masses.

Whether applying the "heat-treating" method - reducing heat for passive or active houses, households need to refer to construction materials from leading brands. In particular, Sika - a corporation that owns a comprehensive solution chain for townhouses from foundation to roof, waterproofing - heat-resistant solutions that exceed expectations will be a choice worth considering for homeowners.
