According to the latest annual energy statistics published by the Ministry of Statistics, Planning, and Implementation, residential and commercial structures in India consumed nearly a third (32 percent) of the country’s total electricity in 2016. Indian buildings have been a constant power guzzler and as Indian cities grow, building energy demand is sure to surge.
To conserve power and resources for future, energy efficient buildings are designed. These buildings help to minimize environmental impacts and reduce greenhouse gas emissions. In addition, these buildings offer better air quality in the surrounding that contributes to a healthy environment and improves the quality of life of people by providing proper ventilation and comfort. These buildings not only contribute to a safe environment but also conserve resources for sustainable development.
Designing or refurbishing to a highly energy-efficient house requires careful planning and detailing. A smart systems approach helps homeowners, architects, and builders to develop successful strategies for optimizing home energy efficiency.
With the advancement of modern technology and innovation, energies can be saved to some extent. In case of an existing building, there are many areas to focus on:
Insulating external facades, especially on southern façade as it is mostly exposed to the heating sun. Companies like Aludecor have come up with Aludecor systems to promote energy-savings for buildings.
Aludecor’s ventilated facades are external finishing systems, fitted with space that allows air to flow between the gaps of the panel and the façade to increase thermal insulation. These facades help the building to conserve energy and thereby reduce bills. The space between the façade and the building reduces thermal transmission and reduces the external heat that enters the building in summers and vice versa in winter. This helps save energy inside the building and reduces cooling or heating expenses.
Applying low-emissivity (low-E) films on windows can help decrease the sunlight. This has a significant effect on buildings with greater window-wall by keeping the interior cool.
Replace regular lights with LEDs for lighting which can help contribute to energy savings and are the most efficient ones. Smart and advanced lighting systems can also be used, that has advanced sensors and controls to adjust for daylight, efficiently directing artificial light to dark or unoccupied spaces and dimming it in areas plenty of daylight.
To save money on lighting one can use automated window shading systems which control the light level and solar heat gain for the building.
