The office building is fitted with a 4-pipe fan-coil system to provide comfort cooling in summer, heating in winter and all-year-round ventilation.
The system is designed generally to the standards set out in the C.I.B.S.E. Guidelines to current practice and to satisfy Part L2A of the 2010 Building Regulations. The Asset Rating of the building is within EPC Band B.
The offices are designed to achieve an air temperature band of 22ºC +/-2ºC at the control sensor when the external conditions vary from -4ºC saturated in winter to a peak of 27ºC dry bulb/18ºC wet bulb in summer. Diurnal and monthly variations from these peak external conditions were assumed in accordance with C.I.B.S.E. standardised data. Relative humidity is not controlled.
Except where otherwise stated, the technical design was based upon one person per 10 nett sq.m. The mechanical system was designed so that the noise was limited to approximately NR38 in open plan areas.
The general arrangement of the system was designed to suit open plan office accommodation in all areas. The system and its automatic control may need to be rearranged to suit the space planning requirements of the tenant.
