“…The research shows that dwellings with hybrid or gas absorption heat pumps have lower gas consumption ranging between 13% to 28%, compared to dwellings with a standard HR107 heating gas boiler, and higher average electricity consumption of up to 50%, with an increase in the average building quality. The gas savings reported by Lu et al (2020) and Famiglietti et al (2021) are higher than the reported difference in gas consumption in this research. The differences in energy consumption cannot be attributed solely to the differences in the type of heating system.…”

“…They report a decrease of up to 27% of CO2 emissions, mainly due to the system's lower gas consumption. Lu et al (2020) report energy savings of up to 43.5% when gas absorption heat pumps are applied in residential buildings, compared to the natural gas boiler. Bianco, Scarpa, & Tagliafico (2017) analysed the prospective energy consumption and CO2 emissions of air-to-air electric heat pump systems in Italy with an end-use approach model.…”

This thesis examines the energy performance of dwellings of Dutch non-profit housing associations towards a future sustainable housing stock. Improving the energy performance of dwellings aims to improve the quality of dwellings and therewith to lower the actual energy consumption. Lowering the actual energy consumption of dwellings contributes to the battle against climate change. This thesis addresses four studies. Study 1 assesses the energy performance progress of over two million dwellings of Dutch non-profit housing associations between 2017 and 2020. It gives insights into the development of the housing stock, the effect of changes of and within the stock, the effect of characteristics of housing associations and it relates the improvement of the energy performance to the sectoral goal. Study 2 assesses advanced models to improve estimations of actual energy consumption of dwellings and therewith to better estimate the effect of renovation measures on actual energy savings. Study 3 assesses the energy performance of dwellings with heat pumps. It gives insights into the energy performance of dwellings with heat pumps as a promising renovation measure towards a future sustainable housing stock. Study 4 assesses the process to create a model to benchmark the energy performance in a changing policy context. The four studies contribute to the understanding of the improvement of the energy performance of dwellings of non-profit housing associations towards a future sustainable housing stock.

“…The gas-fired absorption heat pump type Ⅰ has the potential to upgrade the geothermal heat in order to achieve higher temperature in the heating station. However, this technology has its own limitations since it would consume a certain amount of natural gas and discharge a large amount of atmospheric pollutants [10][11]. The medium-high temperature electric compression heat pump could be another option to upgrade the medium-low temperature geothermal heat to achieve higher temperature in the heating station [12], but its coefficient of performance (COP) would become lower due to higher heating temperature [13][14].…”
