ICT Server Room Ventilation The following section is a minimum specification for the design and installation of the ventilation and associated systems in any server room for Information and Communications Technology (ICT). See Section 4 of the GDB for ICT system requirements. General Requirements Typical server rooms can produce high-density heat loads which can affect ICT equipment. The Contractor shall ensure that environmental conditions are maintained in line with the manufacturer’s recommendations for the equipment to be housed within, or any respective warranty requirements. Security of ventilation openings in the façade shall comply with the GDB. Ventilation Systems, Air Flow and Heat Loads The type of ventilation system required and the strategy to cool the server room will be dependent on the heat generated by the equipment. If a mechanical ventilation system is used this shall be provided with filtration to prevent dust ingress. Server room cooling shall be sized on the sensible heat loads provided by the manufacturers of the equipment to be installed allowing for diversity or the actual measured power consumption of the equipment. An additional load of 10% should be included for future expansion. For modern server rooms it should not be necessary to provide more than 250 W/m² of cooling. Typically, the cooling duty will be in the range of 1.2kW - 6kW for Secondary Schools and 400W 1kW for Primary Schools. – DX or VRF cooling shall be provided to meet the temperatures specified in equipment warranties in peak summertime periods. The normal operating range (set point) shall be designed to meet manufacturer’s recommended requirements. Temperatures may not exceed this range for more than 200 hours a year. The maximum temperature of the room measured at high level above the server racks shall not exceed 28 °C. The minimum temperature of supply air shall be 15 °C. The Contractor minimise the ventilation and cooling required, for example by locating server rooms on the north façade or in areas of the building where there are lower thermal gains and on an outside wall. A ventilation opening to outside or locally controlled extract fan shall be provided to allow for ventilation for occupancy and battery failure. This shall allow for ICT staff who are servicing equipment in the server room; and ventilation required by UPS systems for the safe operation of the batteries to allow for the release of inflammable or corrosive
