elow the maximum comfortable temperature of around 26°C recommended by bothCIBSE in [6] and ASHRAE in [5]. For the 6 household building, similar settingswere adopted as shown in Table 3.4.Table 3.4 - Control settings for cooling season; 6 Household buildingFloor level/ApartmentZoneHouseholdNo.Occupancy(No. ofpersons)Control time periods(Temperature limits)(‘On’ - ‘Off’)CommentGroundFloorLivingAreaBedroomArea2A + 3A 507.00-08.00 Hours15.00-24.00 Hours(24°C - 21°C)00.00-07.00 Hours(24°C - 21°C)Ground floor isvacant between08.00-15.00HoursMiddleFloorLivingAreaBedroomArea3B + 4A 707.00-24.00 Hours(24°C - 21°C)00.00-07.00 Hours(24°C - 21°C)Middle floor isnever vacantTop FloorLivingAreaBedroomArea4B + 2B 607.00-10.00 Hours13.00-24.00 Hours(24°C - 21°C)00.00-07.00 Hours(24°C - 21°C)Top floor isvacant between10.00-13.00Hours3.1.3 Intermediate seasonThe indoor temperature of all apartment zones during the intermediate season, whichcovers the calendar period between the 20 th of March and the end of May and thebeginning of October and the 18 th of December, was uncontrolled for the entireduration of the period. Although during this calendar period daily morning andafternoon temperatures tend to be in the low 20s [9], temperatures are stillcomfortable enough that no cooling is required. Similarly temperatures during theevening are high enough that no heating is required. No form of indoor temperaturecontrol was assumed for any of the apartments during this period. The thermaldemand in this case was therefore exclusively due to the hot water demand.3.2 Satisfying the energy demand - The micro-trigeneration plantconfigurationBefore describing how the micro-trigeneration plant was modelled and controlled tosatisfy the energy demands of the building, Section 3.2.1 elaborates on the building95
