“…The field trial in 12 multi-family blocks with 93 residents, who were exposed to load shifts for two weeks during early winter, showed that no statistically significant difference was found in thermal sensation or thermal satisfaction and that perception and acceptance of DSM in residential space heating is subject to four factors: (1) set indoor climate conditions, (2) timing and magnitude of the load shifts, (3) individual control and (4) communication [10]. Christensen et al [11] showed in a 4-week field trial in three detached houses in Denmark that residents accept changing thermal conditions (temperature boosts) only after additional explanation of the monetary or environmental benefits of such interventions in their typical thermal comfort preferences.…”

Buildings can deliver short-term thermal energy storage to energy systems. In district heating (DH) systems, it is mainly desk studies and simulations that reveal a large thermal flexibility potential. Knowledge from real-life case studies on how residents participate in demand management campaigns is crucial for the successful utilisation of buildings’ flexibility potential for minimizing bottlenecks in the daily operation of DH systems. In the field study including 72 single-family houses connected to the 3GDH network in southern Denmark, the demand response (DR) strategy “night setback” was applied for two heating periods. The houses were equipped with control and monitoring equipment, which allowed the deactivation of the heating system while monitoring the indoor temperature, so it does not drop below the defined value. The occupants controlled the DR events settings and could at any time stop utilisation of the night setback strategy (implicit participation in the DR). All 72 houses applied the night setback during both heating periods. Yet, the participation time decreased from 89% to 81%. The lowest participation rate was noted for the farm house, 60% and 9% of heating periods 1 and 2, respectively. In around 60% of the DR events, the night setback strategy was activated at 20:00.

“…Besides of these studies, there are, to the knowledge of the authors of this paper, no reported investigations on appropriate temperature sensor location to obtain a measurement that reflects residents' thermal sensation and satisfaction. Christensen et al [14] conducted a study mimicking the behaviour of an EMPC for space heating in three residential buildings in Denmark. Utilising digital radiator thermostats, the temperature setpointand thus the indoor air temperature -was increased before a typical morning peak period to load the thermal mass of the building allowing the temperature to drift back to the initial setpoint during the morning peak without using energy for space heating.…”

Economic model predictive control (MPC) of residential space heating utilizes indoor air temperature fluctuations and thermal mass for load shifting of space heating consumption and it can be used for various demand response purposes in district heating systems. A field experiment imitating the behaviour of an MPC has previously been carried out in three residential buildings in Aalborg, Denmark. Here, digital radiator thermostats were used, and it was found that the load shifting period was cut short when using the temperature measurement embedded in the thermostat as control input for the MPC. Therefore, the field study reported in this paper investigated whether using indoor air temperature sensors as control input for the thermostat improved the realisation of the load shifting. The field study took place in a single-family house in Aarhus, Denmark, and tested the load shifting potential when controlling with either the temperature sensor embedded in the thermostat or an offset between the radiator thermostat setpoint and an indoor air temperature sensor measurement. The study indicates that the use of indoor air temperature measurements as thermostat control input will provide longer periods of loading and unloading the building, thereby increasing the total load shifting potential of the heating consumption.
