Loadcalc

Upload your plans. Get the heating and cooling load of every room.

Loadcalc reads the plan set, quotes each dimension back to you with its sheet number, and calculates room-by-room loads following the ACCA Manual J procedure. A qualified designer reviews the result before it goes to your engineer or contractor.

Lot 308

A worked example, so you can see what you get

A 2,413 square foot two-storey house in St. George, Utah, from a 13-sheet plan set. Each room is drawn in plan with its walls weighted by heat loss. Heavy strokes are where the heat goes.

What happens

  1. You pay and upload. One plan set as PDF. Floor plans, elevations, and sections give the best result. A site address sets the climate.
  2. Loadcalc reads the plans and shows you what it read. Every room, window, and wall assembly, each with the sheet it came from. Anything the plans do not say gets a question with a recommended answer. You correct what is wrong and confirm.
  3. The loads are calculated. Heating and cooling for every room and the house, with the assumptions listed.
  4. You explore room by room. See where each room's heat goes. Swap window products and watch the numbers change.
  5. Your files arrive. The report, the schedules, the 3D model, and a link to share. A reviewer checks the job and you get an email when it is marked reviewed.

What the result is, and is not

The report follows the ACCA Manual J 8th edition procedure. Design weather is derived from published station data. The software is not ACCA-approved. It is a first-pass estimate for review by a qualified designer, and it says so on every page. It is not a stamped engineering document and not equipment selection.
