The short answer is no. The Manual J protocol is only applicable for residential buildings with three or fewer above-grade stories and...
"...applies to any dwelling unit that has its own heating-cooling-ventilating system and equipment and its own exhaust air system(s).
This includes:
Single-family detached structures, duplex structures, and triplex structures
Single-family attached structures (row house or townhouse)
Dwelling units in multi-family attached structures (condo and apartment units)
and energy-efficient homes"
Large buildings with complex occupancy behavior or usage (like big loading dock doors that open directly to outdoors), machines, etc. require Manual N (commerical load calculaton method) or special ASHRAE procedures that we don't handle.
Can I use Manual J for large multi-family buildings with more than three stories?
Unfortunately, Manual J can not be used for these buildings. These behave more like commercial buildings and require ACCA Manual N. Very tall buildings have completely different infiltration characteristics, have much more complex load characteristics (very high or very low loads), and thermal storage dynamics that are outside the scope of Manual J.
What about "light commercial" buildings?
If a building has "residential-like" commercial space, it can be stretched, think small cafe without a big production kitchen, or a boutique bookstore or a small church.
Are there other potential limitations for large buildings?
Churches or barns that have been converted into homes or condos can be challenging. They may have very high vaulted or cathedral ceilings. The LiDAR sensor on the iPad Pro has a range of about 15ft so when holding the iPad above your head, you should be able to scan as high as 20-25ft. Beyond that height, you may struggle to capture the surface geometry of the building.
