“…Different national regulations have established a legally binding target of 80% reduction in carbon emissions for 2050 in response to the European regulations. This will require a major effort from countries in southern Europe and the Mediterranean arc to improve a social and ageing housing-stock, mostly obsolescent, whose performance is far from these objectives [1], as may be the case in Spain. Effective and optimized energy intervention and retrofitting techniques must be developed in order to achieve adequate performance of the indoor environments assuring energy conservation.…”

“…However, this situation is not only confined to southern Europe, but is also identified in other colder climates where one would expect a greater climate adaptation of the housing conditions [19]. This situation can be attributed to a widespread lack of heating systems and energy poverty issues affecting these social groups [1], and results in the dwellings being kept closed for most hours during winter.…”

TVOCs and PM 2.5 in Naturally Ventilated Homes: Three Case Studies in a Mild Climate

In southern Europe, the present stock of social housing is ventilated naturally, with practice varying in the different seasons of the year. In winter, windows are kept closed most of the day with the exception of short periods for ventilation, whereas the rest of the year the windows are almost permanently open. In cold weather, air changes depend primarily on the air infiltrating across the envelope and when the temperature is warm, on the air flowing in through open windows. CO2, PM2.5, and TVOC concentration patterns were gathered over a year’s time in three social housing developments in southern Europe with different airtightness conditions and analyzed to determine possible relationships between environmental parameters and occupants’ use profiles. Correlations were found between TVOC and CO2 concentrations, for human activity was identified as the primary source of indoor contaminants: peak TVOC concentrations were related to specific household activities such as cooking or leisure. Indoor and outdoor PM2.5 concentrations were likewise observed to be correlated, although not linearly due to the presence of indoor sources. Ventilation as presently practiced in winter appears to be insufficient to dilute indoor contaminants in all three buildings, nor does summertime behavior guarantee air quality.

“…This housing stock presents deficient energy conditions requiring high energy consumption in order to maintain suitable comfort conditions [4]. However, the socio-economic profile of a large number of users results in living conditions of energy poverty, with environmental deficiencies and discomfort [5]. In the current economic climate, architectural retrofitting, covered by retrofitted supporting policies [6], is a priority in the construction sector.…”

Design and Performance of Test Cells as an Energy Evaluation Model of Facades in a Mediterranean Building Area

et al. 2017

Abstract:The current European energy policies have an influence on the need to rehabilitate the housing stock in order to meet the objectives of the European Union. Most of this housing stock was built without any type of energy regulation in adverse technical and economic conditions and thus is now energetically obsolete. The major rehabilitation effort required must be approached through actions based on previous quantitative energy knowledge of the existing buildings in order to guarantee the efficiency of energy-retrofitted solutions. This assessment can be carried out through monitoring dwellings conditioned by use patterns; through simulation programs, which do not usually offer faithful representations of energy conditions; or by using test cells, which allow us to evaluate a controlled indoor environment without the influence of users. The objective of this paper is to present the design and performance of test cells as an experimental method for vertical facade analysis in order to tackle the problem of retrofitting residential buildings in a Mediterranean climate, taking into account energy and environment. With this equipment, efficiency and energy savings, as well as illumination and interior air quality, can be simultaneously and comprehensively evaluated.

“…In spite of a number of remarkable exceptions [16][17][18][19], the majority of results are based on energy simulations under standard use and operative conditions [20]. In most cases, mainly related to social housing in the Mediterranean climate, the results turn out to be very far from reality [21].…”

Monitoring a Pre-Normative Multi-Family Housing Case-Study in a Mediterranean Climate

Abstract:In Spain, a significant percentage of the residential building stock presents deficient indoor conditions regarding current energy standards, due to having been constructed before the Norma Básica de la Edificación in 1979 (NBE CT 79) regarding thermal conditions in buildings. Current environmental policies pursue a cut in energy consumption and seek improvements in indoor conditions by refurbishing current stock, mainly that constructed between 1950 and 1980. Before any retrofitting action, housing monitoring has become essential for a better understanding of real and passive environmental behavior. This paper aims to present the monitoring in hourly intervals, real-time and post-occupancy conditions of a residential building in Seville, built in the 1950s and belonging to national heritage. The results obtained show major discrepancies between thermal indoor data collected and comfort conditions, both in summer and winter, which are solved by the sporadic use of cooling and heating devices present in the dwellings, thus leading to less energy consumption than expected. This is a common occurrence in multi-family housing units from the Mediterranean arc: there are many periods of the year in which a vast number of the population lives in poor energy conditions.
