Accurate model geometry is necessary and should account for all surfaces of a space or room including the internal walls, ceilings and floors. Block loads and room loads should be calculated accordingly. To keep dry air flowing through building cavities, systems shall be designed with sequence of operations that assure continuous positive pressure with respect to the outdoor environment until the outdoor temperature falls below 4.5C (40F), when the building pressure shall be brought to neutral. To illustrate the impact of diversity factors on peak building load, an energy simulation was performed on a 10,000 sq. Drop or car bottom, box, gantry, crucible, age or annealing, shaker, bell and mesh belt conveyor furnaces are offered. Areas such as storage rooms or mechanical rooms do not have occupancy loads.

With more than 50,000 members from over 130+ nations, ASHRAE is a diverse organization dedicated to advancing the arts and sciences of heating, ventilation, air conditioning and refrigeration to serve humanity and promote a sustainable world. Second, advances in building techniques have improved envelopes and reduce that portion of load/energy use.. On some occasions, a ground-contact floor with high thermal mass may even remove heat from a space during a cooling load calculation. Secure .gov websites use HTTPS Do not underestimate in the calculations because the U value for a 60 mm panel is around 5 W/m2degC. I strongly recommend getting this data from the manufacturer specifications. An ASHRAE research project [1] on office buildings noted diversity factors for lighting ranging from 70 to 85% and for receptacles between 42 to 89%.
