Section 3 5 Ceiling U Value Input the average u value for the reflective ceiling Most reflective ceilings have a u value of 0 330 Plenum Contributions This set of inputs allows you to input the percentage of HVAC cooling loads for lighting walls and roofs from 0 to 100 that contribute to the return air plenum located above the ceiling This is assuming that the return air is NOT ducted in any way The best way to determine these percentages is as follows Lighting Consult the manufacturer of the lighting fixture to determine the percentage of light heat released through the plenum Fixtures that are ventilated will release more heat than unventilated lighting fixtures The percentage of heat contributed to return air ranges from 40 to 60 for ventilated fixtures or 15 to 25 for unventilated fixtures Walls The best way to determine the wall load contributions to the plenum is to take the area of wall located above the ceiling plenum and divide it into the total area of the wall Roofs Since most drop ceilings separate the entire roof from the occupied space it can be argued that 100 of the roof loads are contributed to the plenum However there are radiant loads that will bypass the plenum so it is best to input a percentage value ranging from 80 to 90 If you specify percentages for one or more of these items then you must also input values for the ceiling area and u value discussed above A combination of all these va
