I have a three-story mixed-use building that now needs proper Manual J and Manual S calculations so the MEP drawings can move forward. The ground floor is a general office suite; the second and third floors are identical residential units and the top floor also includes an attic space. Each floor falls in the 1,000–2,000 sq ft range. The two residential levels will house about 3–4 occupants per unit and will be conditioned with heat-pump systems. What I need from you: a complete Manual J load calculation and the corresponding Manual S equipment sizing summary, clearly broken out by floor/zone. Please flag any assumptions you must make—solar orientation, insulation values, window specs, infiltration rates—so they can be cross-checked with the architect. Deliverables • Manual J report (PDF & native file) • Manual S equipment selection sheet with model recommendations • Brief notes on design conditions and inputs used I’ll supply the floor plans, elevations, and any additional data you request right away. Let me know your turnaround time and the software you’ll use (e.g., Wrightsoft, Elite, Cool Calc).

can deliver complete Manual J load calculations and Manual S equipment sizing for your three-story mixed-use building, clearly broken down by floor and zone (office + residential levels + attic considerations). I will calculate heating and cooling loads based on envelope characteristics, occupancy, ventilation, and system type (heat pumps), then select appropriately sized equipment per Manual S with clear model recommendations. I typically use Wrightsoft or Elite Software to ensure accurate, code-compliant results. All assumptions—such as insulation values, window performance, solar orientation, and infiltration rates—will be clearly documented for your review and coordination with the architect. Deliverables will include: • Manual J report (PDF + native file) • Manual S equipment selection summary • Clear notes on design inputs and assumptions I can start immediately once drawings are shared, with a typical turnaround of 2–3 days depending on project details.

Hello, I can prepare a complete Manual J load calculation and Manual S equipment sizing package for your three-story mixed-use building, with results clearly broken down by floor and zone (office + each residential level + attic influence). The calculations will account for heat pump systems, occupancy loads, envelope performance, glazing, and ventilation to ensure accurate sizing for both heating and cooling. I typically use Elite Software (RHVAC) or Cool Calc (ACCA-approved), depending on your preference, and will structure the outputs so they align cleanly with your MEP drawings and coordination workflow. All assumptions—such as solar orientation, insulation R-values, window specs (U-value/SHGC), infiltration rates, and design temperatures—will be clearly documented so they can be verified with the architect and adjusted if needed. The goal is to deliver a precise, code-aligned load analysis that prevents oversizing/undersizing and supports efficient system selection, especially important for multi-use buildings like yours. Typical turnaround is 2–4 days after receiving full plans and inputs. I look forward to supporting your MEP phase.
