The cooling load for a server room in Indian Springs can be determined by carrying out the following operations: 1. **Equipment Heat Load**: The first step is to identify all the equipment within the server room and ascertain their power ratings in watts. These watt ratings should then be converted to BTUs per hour using the conversion factor of 1 watt = 3.412 BTU/hr. The resultant sum will yield the total heat load from server room equipment excluding any considerations of solar heat gain or other ambient internal conditions.2. **Lighting Heat Load**: The next step is to consider the lighting within the server room. This entails identifying all types of lighting fixtures, determining their wattage, converting these numbers to BTUs, and then adding this figure to the previous total.3. **Factor in Your Personnel**: The majority of techs and other personnel will not be present in the server room around the clock, but for every human expected to be in the space, guesstimate that person adds around 400 BTU/hr to the cooling load. 4. **Consider Vents and Ducts**: Now it's time to look at the server room's ventilation system—if it has one. Take stock of the heat gain from any warm air that might be entering the cooling space.5. **Evaluate the Building Shell**: If substantial, determine how much heat is entering the structure through the walls, roof, and floor (the building envelope), using local weather data, detailed construction assembly drawings, and other references to infer the average insulation value of the building materials. Then total all these loads. Finally, apply a safety factor (10-20% is typical) to cover uncertainties, such as poor workmanship, that might allow more heat to enter than planned, or future expansion of the server room.
