Examples
Example comparisons
A useful example shows its inputs, defaults and output definitions. The setup pages below explain questions to test. One fictional house, shown screen by screen with its report, covers a completed run without claiming a comparison result.
Full fictional house report
Follow a fictional house through the six wizard screens and its results, then read the 13-page PDF report. It shows a single simulation's charts, configuration and limitations; it does not compare scenarios.
Summer comfort
Compare shading, ventilation and supported cooling on one building and weather file. Decide which temperature and energy outputs you would inspect.
Heating change
Compare an existing gas or oil system with a supported heat-pump option using the same comfort settings, hot-water demand and weather.
Adding solar panels and a battery
What could PV and a battery change on your annual electricity bill? A current bill gives you a starting point, but it does not show when your house uses electricity. Match modeled consumption and solar production hour by hour, then inspect direct use, storage, grid imports and exports.
Compare the current setup, PV alone and PV with a battery on the same house, weather, schedules and tariff. Separate import charges, export credits and the fixed grid charge. Future heating, cooling or EV use can change the demand you are comparing.
Battery size, dynamic tariffs and an EMS
Which battery capacity fits this house and tariff? Compare capacities with the same power, efficiency and reserve assumptions, then hold the hardware steady to compare basic control with the optimizer. An energy management system (EMS) can change when electricity is stored, used or sold. More self-consumption and a lower bill are different goals.
Dynamic pricing uses your country's day-ahead prices under the product's tariff assumptions. Import and export prices are separate inputs: a dynamic purchase tariff does not imply a dynamic export contract. The optimizer schedules electrical battery and EV flows from the thermal demand already calculated; it does not automatically schedule slab storage or pool setpoints.
Modeled operation is not a promise of installed EMS savings or a lifetime investment optimum. These operating-cost comparisons exclude equipment purchase, installation, financing, replacement and battery aging.
Adding an electric car
How does an EV change your energy use and use of home solar? Keep the same house, PV and battery, then add the car's driving and home-availability schedule. First inspect the added driving demand. Compare charging arrangements that meet the same departure charge requirement; a car at home during solar hours differs from one that returns after sunset.
Inspect EV charging, whole-home solar self-consumption, grid imports, exports and the modeled operating bill. Whole-home self-consumption is different from solar's share of EV charging. Do not infer that share from simultaneous generation and charging or treat grid-charged battery discharge as solar.
Keep bidirectional charging off for the basic EV comparison. Vehicle-to-home is a separate comparison with its own equipment and operating limits.
Why there are no result numbers
A numerical example needs a saved run with its complete input configuration, output, model version and tariff source. Until that evidence is published together, these pages explain how to compare rather than imply a result.
