This MCP server provides a simplified thermal load calculation engine based on the Manual J standard. It allows HVAC professionals and engineers to determine the precise heating and cooling requirements for residential spaces. By using tools like calculate_heating_demand, calculate_cooling_demand, and validate_equipment_capacity, you can calculate heat loss through building envelopes, solar gain from window orientations, and internal heat gains from occupancy. The server also enables checking if a specific HVAC unit's rated capacity is sufficient for the calculated loads.

Calculate the heating demand for a 2000 sq ft space with medium insulation in climate zone 5.

The calculated heating load is 45,000 BTU/h.

What is the cooling load for a 1500 sq ft room with north: 50, south: 20, east: 10, west: 10 window areas and 3 people?

The cooling load is 18,500 BTU/h (approximately 1.54 Tons).

Is a 24,000 BTU unit enough for a load of 20,000 BTU heating and 26,000 BTU cooling?

No, the unit is Underpowered because it does not meet the required cooling load.

It determines the total heating capacity required (in BTU/h) by considering the conditioned area, insulation level, and IECC climate zone.
