To ensure the achievement of the climate and energy policy targets and simultaneously guarantee affordability and inclusiveness, a thorough consideration of institutional settings is necessary, such as the structures of housing provision (SHP), and taking into account low-income households. This paper deals with the following research questions: (1...

Mitigating CO 2 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 CO 2 reduction through thermal renovation activities and the change of heating systems. In this work, we develop cost-optimal balances...

This paper focuses on the requirement of the Energy Efficiency Directive for assessing the potential of efficient heating and cooling. The paper describes the method for calculating the economic potential of efficient district heating (DH) in Austria under different scenarios, assuming the full decarbonisation of the heating sector by 2050. A spati...

Since the introduction of the effective width concept for the estimation of the linear heat density, it has been frequently used by researchers to calculate district heating distribution grid costs in pre-feasibility phases. Some researchers however, still prefer using a detailed modelling approach to get reliable results. This paper aims at highli...

The scope of this investigation is to analyze recent advances in district cooling (DC) in Europe (European Union plus the United Kingdom (EU27+UK)). The study focuses on data and information from the past decade and draws a picture for the year 2016. To date, in contrast to the European district heating market, the European DC branch has barely bee...

Around 25% of final energy consumption in the European Union is currently used for space heating. The potential for reducing this demand through renovation of existing buildings is very significant and recognised to be an important factor for reaching CO 2 reduction targets. In this analysis we develop two types of cost curves for heat savings in b...

The planning of heating and cooling supply and demand is key to reaching climate and sustainability targets. At the same time, data for planning are scarce for many places in Europe. In this study, we developed an open source dataset of gross floor area and energy demand for space heating and hot water in residential and tertiary buildings at the h...

In this work a method for integrated strategic heating and cooling planning applicable for any city or region is presented and applied for the case study city of Brasov. The overall methodology comprises the calculation of the cost-optimal combination of heat savings with either district heating or individual supply technologies for different build...

Im Rahmen des IEA SHC Task 52 erfolgte eine Statuserhebung sowie eine Analyse der zukünftigen Rolle von Solarthermie in städtischen Energieversorgungssystemen. Das Potential solarthermischer Anwendungen zur Deckung des Niedertemperatur Wärmebedarfs wurde vor dem Hintergrund der sich rasant verändernden Rahmenbedingungen im Energiesektor eingehend u...

District heating in general is seen as an important opportunity to decarbonise the heating sector especially in urban areas and therefore important to reach European and global climate goals. In this case study we analyse possible future scenarios for the city of Brasov, Romania. Like in many other cities in Eastern Europe a district heating system...

The purpose of this paper is to investigate the resilience of possible future electricity and heating systems in regard to climate change and fuel price shocks. The dynamical simulation model HiREPS of the Austrian and German electricity, heating and cooling sectors was used for this analysis. The electricity generation cost and changes in the requ...

In accordance with the EU Energy Efficiency Directive all Member States have to develop a comprehensive assessment of the potential for high-efficient CHP and efficient district heating and cooling by the end of 2015. This paper describes the approach and methodology used to determine the district heating potentials for Austria. In a first step act...

The main objective of work package 2 is the assessment of the heat and cooling supply technologies currently installed in Europe. The assessment is split into two parts. Firstly, the technology stock is assessed and described in detail including installed capacities, the number of installed units and their age distribution. Secondly, technical and...

The report one assesses the status-quo of energy demand for heating and cooling in the European countries in the year 2012. The main goal of the WP is the calculation of a consistent European end-use energy balance for heating and cooling. In contrast to classical energy balances that show sectors and energy carriers, end- use energy balances als...

This report presents results of a study conducted to assess the potential for efficient district heating and high-efficient cogeneration of heat and power (CHP) in Austria. The study was conducted on be-half of the Austrian Federal Ministry of Science and Economics and aims at supporting the authorities to fulfill the reporting duties related to th...

While energy savings in buildings is among the key prerequisites for a low-carbon future, our ability to maintain temperatures in buildings within a specific comfort range, and thus our demand for heating and cooling energy, are also highly sensitive to climate change. We quantify two main impact chains: (1) a higher temperature in winter leads to...

Best practice policy design and harmonisation of support schemes for electricity from renewable energy sources (RES-E) within the European Union have been discussed controversially for years. In contrast, policies for improving renewable heating (RES-H) penetration in the European Member States and options for best practice instruments are still be...

The heating sector has been neglected in energy policies for quite some time, especially on the European level. Only recently, with the implementation of the European directive 2009/28/EC the sector has gained higher attention. The objective of this paper is to provide an overview of the heat market in Austria and of the current status and future p...

In the light of the EU directive for renewable energy (2009/28/EC) this paper deals with the question how various policy instruments could impact the development of renewable heating technologies. The paper applies the simulation model Invert/EE-Lab for the building related heat demand in selected European countries (Austria, Lithuania and United K...

The project “Policy development for improving RES-H/C penetration in European Member States (RES-H Policy)“ aimed at assisting the governments of Member States in preparing for the implementation of the EU Renewables Directive 2009/28/EC1 as far as aspects related to renewable heating and cooling (RES-H/C) are concerned. Selected Member States were...

Currently most economies are based on fossil and mineral resources, which end as waste or fossil CO2 emitted into the atmosphere. The vision of a sustainable economy would need the shift to a solar based market. Hereby the use of renewable resources for products and energy services is one of the main challenges. An efficient use of biomass describe...

Within the EU-27 biomass heating covers about 90% of all renewable energy sources in the heating sector (RES-H). According to the NREAPs of EU member states, biomass heating should further increase from 49 Mtoe (2005) to 87 Mtoe (2020). Yet, several questions are open regarding required support policies and the expected technological, economic and...

In many countries such as Austria the energy demand is mainly covered by fossil fuels. The negative impact oil the climate and their decreasing availability brings up the need for a shift to a possible future energy system using solely renewable energy sources. The goal of the modelling is to compare and possibly match the energy demand of Austria...

In vielen Ländern der Erde wird der Energiebedarf in erster Linie über fossile Energieträger bereitgestellt. Schwindende Vorräte und die gravierenden Auswirkungen auf die Umwelt machen es notwendig, auf ein nachhaltiges Energiesystem basierend auf erneuerbaren Quellen umzusteigen. Ziel dieser Studie ist es, die Potentiale erneuerbarer Energieträger...

This research aims at analysing the technical opportunities of a renewable energy in-frastructure for Austria, using a static modelling approach. Bottom-up modelling is used for the most sensitive parts of the system, due to high energy consumption, efficiency potentials or conflicts with non-energetic biomass use. Varying the parameters allows exa...
