“…The model energyPRO [45] has previously been applied by Trømborg to model electricity use in district heating plants [46], by Sneum to investigate flexible district heating [47], by Widzinski to analyse alternative heat production technologies for district heating system in Poland [48] and by Trabert [49] to analyse a river water-based heat pump for district heating in Germany. Beyond the present journal, it has been applied to develop low-carbon pathways for various case studies including Helsingør [50], Helsinki [51], Pécs [52], Matosinhos [53], and Brasov [54].…”

This 38th volume of the International Journal of Sustainable Energy Planning and Management presents some of the newest work within in the energy planning, energy systems analyses and district heating area. Articles focus on multi objective optimisarion for a community in the Alps, carbon neutrality in Estonia, the prospects of heat pumps combined with thermal energy storage in maximising self-consumpotion from a photovoltaic field and methods for assessing district heating options. Other work focus on gamification tools for assessing energy efficiency measures, country analyses of economic and environmental indicators, the adaption of alternative fuel vehicles, and the use of waste heat sources for district heating.

“…Ben Amer-Allam et al (2017) and Büchele et al (2019) study how to identify cost-optimal mixes between district heating, individual heating and heat savings for the municipality of Helsingor in Denmark and the city of Brasov in Romania, respectively. Both analyses integrate the area's building stock via archetype buildings and related heat-saving measures, distinguishing between areas of the city that are more or less feasible for DH.…”

“…For Helsingor, cost-optimal savings are calculated to be 20-39%, mainly depending on the economic perspective (simple socio-economic vs private-economic) and less on the assumed technology mix in the DH system. Büchele et al (2019) calculate a cost-optimal level of heat savings in Brasov to 64% over the entire stock until 2050, which is equal to the overall identified technical heat-saving potential with very ambitious measures. This is generally explained by relatively low renovation costs compared to the heat supply costs, as well as the analysis method.…”

How cost-efficient is energy efficiency in buildings? A comparison of building shell efficiency and heating system change in the European building stock

Mitigating CO2 emissions for space heating (SH) and hot water (HW) preparation in buildings is key to reaching climate protection targets. In this context, it is important to understand meaningful balances between CO2 reduction through thermal renovation activities and the change of heating systems. In this work, we develop cost-optimal balances for different system settings with the Invert/Opt model. This model optimises the measures applied in each building so that the system costs for SH and HW preparation are minimised under given constraints for a given country. About 500–1000 options are considered for each building. We calculate scenarios and sensitivities for all countries of EU-27, reflecting a 95% reduction in CO2 emissions for SH and HW with a mix of direct and indirect RES technologies. These differ in the settings related to the applicability and costs of building-shell-related measures and the costs and availability of resource potentials. The results show that probably a high share of thermal renovation on total upcoming refurbishment activities until 2050 is cost-efficient to reach a 95% CO2 reduction in the EU-27 building stocks. Assuming that up to 90% of the buildings in each EU-27 country is applicable for a thermal renovation in case a refurbishment activity is needed leads to around 4% lower system costs by 2050 (13 billion EUR/year) compared to assuming a maximum share of 35%. Energy needs are reduced on average more in older buildings than in newer buildings. Nonetheless, a combination of thermal renovation and heating system change is often the most cost-effective option to reduce system-wide CO2 emissions also in more recent buildings. The calculations lead to cost-optimal savings in final energy demand in the range of 29–47% between 2019 and 2050. Assuming less favourable conditions for thermal renovation (high capital recovery expectations, additional technical barriers and high availability of cheap fuels) the cost-optimal level of heat savings in buildings for overall EU-27 could be suspected at around 1/3 down to 1/4 of current final energy demand.

Investigating pathways to a net-zero emissions building sector in the European Union: what role for the energy efficiency first principle?

et al. 2023

European Union (EU) legislation is increasingly embracing the energy efficiency first (EE1st) principle. This principle seeks to prioritise energy efficiency measures whenever these involve lower costs to society than generators, networks and other energy supply options while achieving the same outcomes. This study contributes to the quantitative evidence on the relevance of EE1st by modelling the impact of moderate to ambitious end-use energy efficiency measures on energy supply and the associated system cost under a net-zero greenhouse gas emissions constraint by 2050. These measures focus on the EU building sector and include both building retrofits (e.g. wall insulation) and efficient products (e.g. lighting). The results indicate that implementing more ambitious energy saving measures reduces the total electricity, heat and hydrogen capacities needed to achieve the net-zero target. Reducing energy use in buildings by at least 21% between 2020 and 2050 is essential to avoid excessive energy supply costs. This requires actions that go well beyond business-as-usual trends. Reductions of around 30% could be justified on the grounds of (i) high fossil fuel prices and (ii) multiple impacts (e.g. health benefits). Overall, the outcomes provide reasonable justification for the EE1st principle. To put the principle into practice, policy actions such as doubling building renovation rates and setting higher energy efficiency targets are key.
