“…Computer-aided energy simulation has proven to be a fast, economic and accurate method of predicting energy consumption in a building and assessing the benefits of building refurbishment [63,64]. The energy simulation of the building begins with modelling the geometry and composition of the thermal envelope of the buildings, as well as the building's internal zoning (using the engine tool EnergyPlus).…”

The actual energy consumption and simulated energy performance of a building usually differ. This gap widens in social housing, owing to the characteristics of these buildings and the consumption patterns of economically vulnerable households affected by energy poverty. The aim of this work is to characterise the energy poverty of the households that are representative of those residing in social housing, specifically in blocks of apartments in Southern Europe. The main variables that affect energy consumption and costs are analysed, and the models developed for software energy-performance simulations (which are applied to predict energy consumption in social housing) are validated against actual energy-consumption values. The results demonstrate that this type of household usually lives in surroundings at a temperature below the average thermal comfort level. We have taken into account that a standard thermal comfort level may lead to significant differences between computer-aided energy building simulation and actual consumption data (which are 40-140% lower than simulated consumption). This fact is of integral importance, as we use computer simulation to predict building energy performance in social housing.

“…One can notice from information provided in Table 1 that the largest barrier to energy efficiency improvements and GHG emission reductions in residential buildings is the high initial costs of energy renovation in buildings households have very limited time to recover the cost of their investments in renovation [58][59][60][61]. Another important issue is that success of policies in this area depend on more than one stakeholder.…”

Climate Change Mitigation in Households between Market Failures and Psychological Barriers

Though there are areas of climate change mitigation linked to household’s energy consumption having huge greenhouse gas (GHG) emission reduction potential as energy renovation or installation of micro generation technologies using renewable energy sources, these GHG emission reduction potentials are not realized so far. The main input of the paper is to overcome this gap and to provide a systematic review of the main barriers of climate change mitigation behavior linked to energy consumption in households and to develop policies to overcome these barriers. The main policies and measures to reduce GHG emissions of energy combustion in households are promotion of renewable energy consumption and energy efficiency improvements however, these policies have been not successful in overcoming some important barriers of climate change mitigation in households. The empirical evidence of behavioral failures is deepened in this paper and the correlation between market barriers, unsuccessful climate change mitigation policies and behavioral and psychological barriers is provided based on systematic literature review.

“…Delivery is reliant on a substantial increase in the pace of retrofit, particularly hard-to-treat homes. This in turn requires that responsibility be taken for carbon reduction across the sector, to drive uptake and deliver results as quickly as possible, because a sufficiently incentivised and skilled workforce does not currently exist to implement even the measures that could have a return on investment over their lifetime (Warren & Griffiths 2017;Patterson 2016). The performance gap has also been identified as a major issue (Palmer et al 2016).…”

This paper examines whether and how the challenging target of 95% decarbonisation can be achieved for the Welsh building stock. First, a critical review of the literature and relevant case studies are presented to understand the effectiveness of different retrofit approaches in practice, and the degree to which these approaches are evidence based, and applicable to the Welsh context. These findings are synthesised into a collection of 14 recurrent dwelling 'archetypes', with appropriate retrofit strategies developed for each. The impacts of these strategies are modelled in terms of capital cost, primary energy use, fuel bills and carbon emissions. Conclusions provide an evidence base for future policy and a decarbonisation strategy. Retrofit strategies should include fabric firstmeasures to minimise increases in household fuel bills and a consequent increase in fuel poverty. Retrofit options for a significant percentage of housing are constrained by character, which would limit changes to the external fabric. Given that decarbonisation of the future energy supply is currently uncertain, all other housing should be retrofitted to perform beyond SAP90. A flexible approach that pushes all housing to achieve stringent standards by 2050 is the only way to achieve targeted reductions in carbon emissions under the assumed energy supply scenarios. Policy relevance The Welsh housing stock, among the oldest and least efficient in Europe, is responsible for 21% of Welsh carbon emissions. In 2019, the UK Committee for Climate Change (CCC) determined that Wales should target a 95% reduction in emissions by 2050. This paper assesses whether this challenging target can be achieved, and potential strategies for doing so. Key recommendations are drawn from the research, which encompass technical, social and organisational issues, and the importance of a holistic approach to decarbonisation is identified. These findings informed the Independent Steering Group recent report Better Homes, Better Wales, Better World (2019), and the report's recommendations were adopted by the Welsh Government on 24 September 2019. This work should continue to provide an evidence base upon which future policy can be developed through the development of retrofit strategies for recurring dwelling archetypes and a decarbonisation strategy for Wales that is likely to include legislation, regulation, incentives and penalties.
