“…A large number of international modelling studies, such as in Argentina [12], Belgium [13], Germany and The Netherlands [14], Kuwait [15], and USA [16] have demonstrated that energy and environmental performance of existing buildings can be improved through appropriate retrofit methods; however, actual energy savings due to the implementation of retrofit measures in real buildings can be different from those estimated [17]. The following study, along with the RfF programme, defines this difference as the performance gap, i.e.…”

This paper uses a socio-technical building performance evaluation (BPE) approach to assess the pre-and post-actual performance of two discrete deep low energy retrofits in the UK-a Victorian solid-wall house and modern 1990s cavity-wall house. A 'low-energy first, then low-carbon' approach was adopted in both cases, to achieve an 80% reduction in annual CO 2 emissions. Preretrofit, both houses had lower measured annual gas consumption as compared to predictions made by energy models, although the electricity consumption in the modern house was higher than modelled, due to occupancy pattern and occupant behaviour. Post-retrofit, it was found that the Victorian house achieved nearly 75% CO 2 reduction, while the modern house achieved only 57% CO 2 reduction over the baseline emissions. Key reasons were higher than expected air permeability rates, installation issues with micro-renewable systems, lack of proper commissioning, usability of controls, occupant preferences and behaviour. Despite the gap between expected and actual carbon emissions, occupant comfort and satisfaction was significantly improved across both retrofits. This evidence-based understanding of the process and outcomes of deep low carbon retrofits is vital not only for learning and innovation, but also for scaling-up deep retrofit programmes for meeting national and international carbon targets.

“…In this case the equipments used for heating are open fi replaces, heat stoves, portable and fi xed heating devices ( Figure 12). About 14% of the usual residential lodging does not own any kind of heating device [25]. Comparatively to the energy consumption in households in Europe (independently if it is North & West, Central & East and South Europe), Portugal has a much higher electricity consumption (42, 60%).…”

“…Southern European countries have the less energy use, per person, for household; according to the International Energy Agency, range from 3370 kWh/person in Portugal, 3600kWh/person in Spain and reach 11,400 kWh/ person in Finland and 17,700 kWh/ person in Luxembourg. The European reality is comparable with 10,350 kWh/person in USA, where residential building energy use represents about 20% of total energy consumption and 11,160 kWh/person in Canada [16,25]. However, besides Portugal has a small consumption, when compared with other countries, the electrical energy consumption has the trend to keep growing [14].…”

The article aims to evaluate the Portuguese building stock energy policies and strategy for energy saving in buildings among the EU members. It was found out the average heat transfer coefficients of the main structural elements of Portuguese Buildings and analyzed the U-values of this elements considering different time periods. The fundamentals of this study were funded by the Agency for Development and Innovation (ADI) and co-financed by the European Regional Development Fund (FEDER) through the Operational Program for Competitiveness Factors (POFC) assigned to the Building Physics and Construction Technology Laboratory with the reference SB Tool SPT_2011_4.

“…Brecha et al [13] used a 1134-house sample in Yellow Springs, Ohio, that consisted of utility usage information for 2006-2008 and the structural characteristics as given in property tax records. They also conducted "light" house audits in the houses and collected information such as window and wall sizes, R-values for wall, slab/foundation, window and ceiling insulation, and efficiency for HVAC equipment.…”
