eLoad Calculator vs ManualJ Lite

Electric Load Calculator is an important electric calculation tool, which enables the determination of the total electrical load needed in a structure. There is a capability of deciding the correct electrical capacity by power consumption calculation of connected loads. This helps in establishment of secure electrical power supply systems, avoids overloading and compliances with the set electrical codes. Applied in dwelling places, offices, and factories, it assists in the creation and improvement of electrical networks.

ManualJ Lite is a fast, offline heating and cooling load estimator for houses. Enter the building, pick the climate zone, and read the cooling load, the heating load and the equipment size in seconds. WHAT IT CALCULATES Cooling load (BTU/h), itemised: - Walls, ceiling, window conduction and window solar gain - Internal gains, ventilation and infiltration - Tons, and the next nominal size at or above the load Heating load (BTU/h), itemised: - Walls, ceiling and windows - Ventilation and infiltration INPUTS - 8 IECC climate zones and 16 California Title 24 climate zones, with outdoor design temperatures you can edit for your location - Separate indoor setpoints for cooling and heating - Floor area, ceiling height, window area and occupants - Wall and ceiling insulation, selected separately - Window type, or the U-factor and SHGC from the NFRC label DOCUMENTED SIZING REPORT (IN-APP PURCHASE, PER REPORT) A clean, signable PDF of the estimate for proposals, customer files and job folders: every input, each load component, the formulas with your numbers substituted, where the design temperatures come from, and signature lines. Preview the whole report before you buy. A purchased report can be exported again for the same house at no extra charge. GOOD TO KNOW - This is a simplified whole-house block load on a single-storey, square footprint. It is not ACCA Manual J and the report is not a permit document. Where a permit, rebate programme or certification requires ACCA Manual J, use ACCA-approved software. - Not calculated: basement, slab and floor losses; duct gains and losses. - Works completely offline.
