This should be a project in C# WinForms, and I must have full access to the code because I will defend this work and need to explain how everything is implemented. This is a graduation project in physics on the topic of "Alternative Energy Sources", and my main task is to conduct a comprehensive study of an energy-efficient house.
In the program, the user should be able to set all the parameters of the house (area, materials/insulation, heat losses, ventilation, number of residents, climate/location, etc.) so that the calculations are realistic rather than conditional. The program should perform accurate calculations of energy consumption and energy generation, including the use of renewable sources (for example, solar panels, and additional systems if necessary), and show the advantages of an energy-efficient house: energy savings, reduced costs, and environmental impact.
It is also necessary to add visualization of the results: tables and/or graphs (for example, consumption and generation by months, scenario comparisons, percentage of needs covered, energy from the grid, etc.) so that the project looks voluminous and large-scale. A separate part is economic calculations: total investments in equipment, annual savings, payback period, the ability to compare several scenarios (for example, different capacities of the solar system, presence/absence of a battery).
In summary, the program should not just be a calculator, but a research system that allows entering real parameters of the house, conducting calculations, comparing options, and clearly demonstrating why an energy-efficient house is a beneficial and viable solution.
