Residential heating and cooling currently account for approximately 7% of electricity consumption in India. However, with a warming climate, the demand for residential cooling is expected to increase while heating needs will decrease. This poses a significant challenge for India, which primarily requires cooling solutions. To address this issue and reduce the energy and carbon footprint of the Indian building sector, it is crucial to assess the impact of climate change on future heating and cooling needs and develop energy-efficient solutions. In this study, conducted by Raj S. Srivastava, A. Aravinda De Chinnu, and Aakash C. Rai, the researchers evaluated the effect of climate change on the heating and cooling energy needs of an archetypical residential room in India across all climate zones. They developed a novel approach to quantify the heating and cooling load components such as walls and windows to identify specific building elements that should be targeted for improving energy efficiency. The findings indicate that under median climate models, the cooling energy demand for this archetypical room would increase by 23-155% by the 2090s compared to the 1990s. The extent of this increase depends on both city location and emission scenarios considered. Walls and windows were identified as major contributors to over 60% of cooling needs, making them prime targets for energy-efficiency measures. On the other hand, there are projected reductions in heating requirements ranging from 45-100% for the archetype room by the 2090s. Walls were found to contribute over 67% to heating needs, suggesting that they should be specifically targeted for reducing heating energy consumption. Overall, this research highlights the urgent need to address future changes in heating and cooling demands due to climate change in India's building sector. By focusing on improving energy efficiency in key areas such as walls and windows, it is possible to mitigate some of these challenges while reducing both energy consumption and carbon emissions associated with residential heating and cooling.

Climate Change and Residential Heating and Cooling in India

As the world continues to warm, the demand for residential cooling is expected to increase while heating needs will decrease. This poses a significant challenge for India, which primarily requires cooling solutions. To address this issue and reduce the energy and carbon footprint of the Indian building sector, it is crucial to assess the impact of climate change on future heating and cooling needs and develop energy-efficient solutions. In a recent study conducted by Raj S. Srivastava, A. Aravinda De Chinnu, and Aakash C. Rai, researchers evaluated the effect of climate change on the heating and cooling energy needs of an archetypical residential room in India across all climate zones.

Background: Residential Heating & Cooling in India

Currently, residential heating and cooling account for approximately 7% of electricity consumption in India. With a warming climate, this number is expected to rise significantly over time if no action is taken to improve energy efficiency or reduce emissions associated with these activities. As such, it is essential to understand how climate change will affect future heating and cooling demands so that appropriate measures can be taken to mitigate them.

The Study

In their study, Srivastava et al developed a novel approach to quantify the heating and cooling load components such as walls and windows in order to identify specific building elements that should be targeted for improving energy efficiency. The findings indicate that under median climate models, there would be an increase in cooling energy demand for this archetypical room ranging from 23-155% by 2090s compared with 1990s levels depending on both city location as well as emission scenarios considered. Walls were found to contribute over 67% towards total heating needs while windows contributed more than 60% towards total cooling needs - making them prime targets for improving overall energy efficiency within buildings across all climates zones in India..

Implications & Recommendations

Overall, this research highlights the urgent need to address future changes in heating/cooling demands due to climate change within Indian buildings sector through improved energy efficiency measures targeting walls/windows specifically - which could help reduce both electricity consumption as well as carbon emissions associated with residential HVAC systems . By focusing on improving insulation/energy performance standards within these key areas , it may be possible not only mitigate some of these challenges but also lead towards greater sustainability within Indian building sector going forward .
