- This paper presents a methodology for systematic description of the EU building stock through archetype buildings with the aim to form a basis for analysing the potential for and cost of energy saving measures. The analysis includes the residential and non-residential sectors. Four countries in different climate regions, accounting for about half of the final energy consumption of EU-27 buildings, have been selected for the study, namely: France, Germany, Spain and UK. The number of archetypes per country has been defined corresponding to different categories of building type, construction year, climate region and main fuel source for heating. The accuracy of the description is validated by simulating energy demand with the building stock model ECCABS, and comparing the modelled final energy demand with corresponding data from statistics. The calculated total final energy demand for each country is within -9% and +3 % deviation from available statistics, which is considered satisfactory.

Energy usage and technical potential for energy saving measures in the Swedish residential building stock
- 2013

Ingår i: Energy Policy. - : Elsevier BV. - 0301-4215. ; 55, s. 404-414

Tidskriftsartikel (refereegranskat)abstract
- This paper provides an analysis of the current energy usage (net energy and final energy by fuels) and associated carbon dioxide (CO2) emissions of the Swedish residential building stock, which includes single-family dwellings and multi-family dwellings. Twelve energy saving measures (ESMs) are assessed using a bottom–up modeling methodology, in which the Swedish residential stock is represented by a sample of 1400 buildings (based on data from the year 2005). Application of the ESMs studied gives a maximum technical reduction potential in energy demand of 53%, corresponding to a 63% reduction in CO2 emissions. Although application of the investigated ESMs would reduce CO2 emissions, the measures that reduce electricity consumption for lighting and appliances (LA) will increase CO2 emissions, since the saved electricity production is less CO2-intensive than the fuel mix used for the increased space heating required to make up for the loss in indirect heating obtained from LA.

Modelling opportunities and costs associated with energy conservation in the Spanish building stock
- 2015

Ingår i: Energy and Buildings. - : Elsevier BV. - 0378-7788. ; 88, s. 347-360

Tidskriftsartikel (refereegranskat)abstract
- The aim of this paper is twofold: to investigate the applicability of a building-stock modelling methodology to assess the potential of Energy Conservation Measures (ECMs) and their associated effects on carbon dioxide (CO2) emissions for a building stock in a South European climate, with Spain being used as an example; and to analyse the technical potentials and costs of the ECMs when applied both individually and as packages of multiple ECMs for the entire Spanish building stock, including residential and non-residential buildings. The modelling methodology, which has been designed to be applicable to any European country, is fully dynamic and based on an aggregated description of the building stock. This paper updates and validates the methodology to account for the climate and technical characteristics of the region under study. Applying all ECMs as a package gives a potential technical reduction in final energy demand of 55% and a 65% reduction in CO2 emissions, while the corresponding techno-economical potentials are 33% and 37%. Nevertheless, the market potentials estimated are substantially lower (5–10%), which indicate that policy shifts are needed if the techno-economic potentials identified in this work are to be realized.

Regionalization of buildings-stock description as basis for evaluating energy conservation measures - South East Norway and South West Sweden

Konferensbidrag (refereegranskat)abstract
- This paper presents a description of regional building stocks in the South West of Sweden and the South East of Norway and provides a first validation by means of modelled Final Energy Demand, which is compared with available statistics. The aim of the work is to provide a basis for modelling the assessment of effects and costs of various energy conservation measures applied to the existing building stocks of regions within a country. The aggregated descriptions of the national building stocks of Sweden and Norway through representative buildings are downscaled to the regions. We conclude that the uncertainty in the methodology applied is higher for the regions than for the national level, due primarily to less data available for validation than on the national level. This uncertainty raises concern about how targets on increased energy efficiency and emissions reductions and are going to be monitored, if such targets are to be fulfilled.

Konferensbidrag (refereegranskat)abstract
- The aim of this work is to develop a bottom-up methodology that can assess energy efficiency and carbon dioxide (CO2) mitigation strategies in the existing building stock. The work concerns the European building stock and is part of an overall analysis of how the European energy system can be transformed to be more sustainable. This paper reports on the validation of the methodology through its application to a sample of 1400 buildings representative of the Swedish residential stock based on data from 2005. Energy and CO2 assessments are performed; all the resultant potentials are presented as a function of costs for the energy-saving measures studied. The results obtained for Sweden are compared to results available in the literature and discussed in relation to the further application of the methodology to the European building stock as a whole. Such application must take into account national differences in energy supply systems (heat and electricity) and characteristics of the building stock. In addition, the use of sample buildings is data intensive, and data may not be available for some European Union member states. Thus, the next step should be to further develop the model so as to be able to also use archetype buildings instead of sample buildings, allowing the use of national statistics and general information on building characteristics as model input. Transaction costs and interactions of demand side and supply side should also be included in the cost calculations.

NORDICCS CCS roadmap
- 2014
-
Ingår i: Energy Procedia. - : Elsevier BV. - 1876-6102. ; 51, s. 1-13
-
Konferensbidrag (refereegranskat)abstract
- The Nordic CCS roadmap is developed in the NORDICCS project, a collaborative research project between leading CCS research institutions in the five Nordic countries. The roadmap will outline jointly developed Nordic strategies for widespread implementation of CCS in the Nordic countries in order to help Nordic industries meet a carbon constrained future with a high price on carbon emissions. It will identify pathways and milestones for large-scale Nordic implementation of CCS resulting in beneficial economies of scale that will increase the likelihood of implementation. Several novel cases will be presented that reveal future Nordic opportunities, including industrial CCS where emitters have large point sources of CO2 localized in clusters, and natural gas sweetening with the potential for use of Enhanced Oil Recovery (EOR) to defray the costs. Recommendations will be made for actions relating to joint political work in the Nordic region for improving the framework conditions for CCS.
