Energy consumption for heat loss in an apartment or house depends on several factors, including the level of thermal insulation, design features of the building, climatic conditions and the use of the heating system. The following are some of the main factors that influence heat loss energy costs:
Insulation: The effectiveness of a building's insulation plays a key role in how much heat is lost through the walls, floors, roof and windows. The better the building is insulated, the less heat loss.
Windows and doors: Windows and doors can be sources of heat loss. Highly efficient double-glazed windows, as well as well-insulated doors, help reduce energy consumption.
Ventilation: Supply and exhaust ventilation can be a source of heat loss, especially if the system is not equipped with a heat exchanger.
Heating system: The efficiency of the heating system, its regulation and the presence of automation also affect the overall energy consumption.
Climatic Conditions: In cold climates, winter heat loss may be higher due to the greater temperature difference between the indoor and outdoor environments.
breakdown of the percentage of penetration (heat loss or gain) through various building components. If I understand correctly, these percentages represent a fraction of the total heat output of each component. Here's a summary:
infiltration : 25%
Windows: 20%
Roof: 15%
Floor: 11%
Walls: 28%
Door: 1%
These percentages indicate the relative contribution of each building component to the total heat loss or gain of the structure. Improving the energy efficiency of these components, for example by improving insulation, using energy efficient windows and sealing gaps and cracks, can help reduce overall energy consumption and improve building comfort and efficiency. Please note that these values may vary depending on specific building characteristics and conditions.
To reduce energy costs due to heat loss, the following measures can be taken:
Improving thermal insulation: Insulation of walls, roof and floor.
Replacement of windows and doors: Use of energy-saving double-glazed windows and well-insulated doors.
Regular heating system maintenance: Ensure equipment is working properly.
Installation of heat pumps or solar collectors: Use of renewable energy sources for heating.
In addition, some countries have programs to subsidize and reward energy-saving technologies that can help you reduce the cost of improving the energy efficiency of your home.
