Energy loss in a home is a very important issue, as it directly affects both comfort and financial cost. To better understand where the greatest energy losses occur, it is essential to examine the main parts of the house that are affected. Below are specific percentages that illustrate how much energy is lost in each case, providing a clear picture of where improvements should be prioritized.
35% of energy loss in a home is due to wall insulation. Proper wall insulation can significantly reduce heating and cooling costs.
25–30% of heat escapes through the roof. If the roof is not adequately insulated, it can lead to additional heating expenses.
15–20% reduction in energy consumption can be achieved by replacing regular windows with energy-efficient ones.
20–50% reduction in energy bills, depending on geographic location and system size, can be achieved in homes with solar panels. Their presence alone can cover 40–70% of annual energy consumption for hot water.
30% of energy for heating, cooling, and lighting can be saved by installing smart thermostats and lighting systems. These systems can adjust temperature and lighting based on space usage and user needs.
10–15% reduction in energy consumption can be achieved by installing underfloor heating systems, compared to traditional radiator systems.
30–50% less energy is consumed by modern air conditioning systems with inverter technology compared to traditional non-inverter systems.
15% savings on lighting energy consumption can be achieved with motion sensors, preventing energy waste when no one is in the room.
75–80% reduction in lighting energy use can be achieved by replacing traditional bulbs with LED lights. While the initial cost of LEDs is higher, their efficiency and long-term savings are significantly greater.
5–10% increase in a building’s value can result from energy upgrades, thanks to lower operating costs and improved quality of living.
Up to 30% less energy for heating and cooling can be consumed by installing green roofs (vegetated rooftops), which also improve air quality and absorb rainwater.
In total, energy-efficient homes can reduce their annual energy expenses by up to 50–60% through the use of sustainable materials, proper insulation, and smart systems.
Smart choices today shape a sustainable tomorrow.
