Urban Residential Energy Efficiency - Technology Optimization and Behaviour Change:
Case study on social housing in Darmstadt, Germany.
Technische Universität Darmstadt
Dissertation, Erstveröffentlichung
Kurzbeschreibung (Abstract)
Energy efficiency has been the core challenge and task of research in the building sector and strongly driven by real estate, resource management, energy policy and consumers with various socio-economic backgrounds. In Germany, the average share of final energy for residential sector accounted for 26% of total final energy consumption (BMWi, 2017), which was almost double than the worldwide average level with 12.6% (EIA, 2017).
Existing building energy analysing tools have achieved a high dynamic dimension of energy consumption through accurate analysis of the technical integration of building energy system. However, the impact of occupant interactions with the control of indoor environmental quality on building energy performance is underestimated. Residential energy consumption varies with physical differences in the size of dwellings, type of properties, age of residential buildings and efficiency of domestic electrical appliances and energy equipment, climate and energy prices, as well as occupant behaviour, in particular, which are affected by individual socio-economic background. A balance between reducing energy bills and without sacrifices of living comfort is pursued by all stakeholders related to residential energy use. Though building energy-saving technologies, low-energy building concepts and building energy management system have reached to a mature degree, a gap between the designed and real residential energy consumption appears often.
This research work considered occupant behaviour as an important influencing factor in controlling indoor environmental quality and energy consumption. A case study on en-ergy consumption of German social housing was discussed. The process of collecting occupant behaviour data and the technological support were introduced, which were based on projects about social housing energy efficiency and those data works as basic input for further simulation process. A new concept was proposed through integrating occupant behaviour into the conventional Retro-commissioning methodology, so as to explore the energy conservation potential of the interaction between occupant behaviour and building energy system.
IDA ICE as the modelling tool in this work was simulating the energy consumption of the total building, and the individual energy consumption and indoor air quality of each dwelling, as well as the living comfort indices respectively. A series of comparison on those simulation results among different dwellings with different occupancy rate and using schedules of energy-related appliances as well as other potential influencing factors were presented to prove the synergic effect of objective (technics) and subjective (occupants) impacts on home energy consumption and indoor environmental quality.
