“…To further advance knowledge in this area in Spain, two studies were carried out in the first Bolueta Tower [23,24]. Additionally, numerous studies deal with mitigation measures in this type of building, but without necessarily clarifying what the alternative roadmap for nZEBs in Spain should be [60][61][62][63].…”

In the last decade, several European directives have been established to contribute to the 2020, 2030 and 2050 energy saving targets and impose energy efficiency requirements for new construction, existing buildings and building renovation operations. One of the ways to achieve said objectives is to rely on the most demanding energy efficiency labels existing in Europe, such as Passivhaus, and to implement similar concepts into the national energy regulations of European countries based on a high-performance thermal envelope (high insulation and high-performance windows), high airtightness and high-performance heat-recovery ventilation systems, and solar heat harvesting. This energy conservation concept has shown to be effective for houses with low-density occupation in cold climates, but may cause severe overheating problems in denser collective housing in temperate and hot climates with higher solar radiation. To assess this impact, five flats in three developments from different periods that range from no insulation at all to a nZEB, Passivhaus-certified high-rise are compared in this paper, using data from a monitoring campaign during the summer of 2020. The results show and quantify the strong impact the evolution of the energy saving regulatory trend has had on summer indoor comfort, which may in some cases lead to previously unnecessary air conditioning for cooling and, ultimately, be counterproductive towards the end goals of reducing energy consumption and greenhouse-effect gas emissions and mitigating climate change.

Current literature and guidelines on sustainable design often debate on the advantages of natural ventilation (NV) and mechanical ventilation (MV) on indoor environment and energy consumption. The present systematic review explores the existing literature comparing NV and MV on the indoor comfort and well-being points of view. The findings emphasize that thermo-hygrometric comfort is the main driver of occupants’ ventilation behavior, while ventilation design is mainly led by indoor air quality targets. Moreover, more recent papers (especially after COVID-19 outbreak) emphasize the necessity of a health-based approach, contrasting airborne pathogens transmission. In this sense, MV is more frequently recommended in public spaces, while hybrid ventilation (HV) is often suggested as a solution to both ensure proper indoor conditions and energy savings. The concept of well-being is currently under-explored, as the present literature only refers to comfort. The same happens with topics such as visual, acoustic, and multi-domain comfort, as well as passive techniques such as night cooling, or analysis of specific environments such as healthcare facilities. Current knowledge would benefit from an expansion of future research in these directions. The choice of the best ventilation solution cannot ignore the context, type, and condition of energy efficient buildings, in order to properly take into account occupants’ well-being.

“…On the other hand, the kitchens in rural settings were at separate house locations (29.5%). The orientation and location of windows determine the quality of natural ventilation, increase indoor air change, and control the ambient temperature in a dwelling (Nag, 2019;Figueroa-Lopez et al, 2021). The types of window openings found in the houses are depicted in Figure 8.…”

Bioclimatic design is a crucial strategy to achieving the eco-friendliness, human-friendliness, and energy-friendliness of the built environment. The building patterns, materials, innovation, and use depend on the inhabitant’s choices, lifestyle, and economic viability. The study focused on examining bioclimatic components of low-cost dwellings in rural coastal environments in eastern India. A survey questionnaire administered to about 1,300 respondents from 15 villages (classified as remote rural, rural, and semi-urban) yielded their perception of different dwelling environment issues. The statistical analysis of bioclimatic dimensions indicated a significant difference among the dwellings. The low-cost mud houses of the remote rural and rural areas in coastal regions often follow local practices. Besides, different dimensions covered in the survey provided insights for the comparative evaluation of different categories of dwelling units. Principal component analysis (PCA) identified the clusters and component structures of the built environment characteristics provided from the response of the villagers as their perception of the dwellings. PCA yielded three components—1) interior design (PC1, building form, partitioning of rooms, type and materials of the wall, roof and window), 2) innovation of the built environment (PC2, building envelope, insulation, and sanitation facilities), and 3) natural ventilation priority (PC3, window design, window opening, and glaze material), which together explained 69% of the total variance. The psychrometric chart provided in identifies passive design strategies in constructing dwellings to improve residents’ yearly total thermal comfort hours in hot and humid regions. The relative contributions to thermal comfort hours are sun shading of windows (25.5%), a passive solar direct gain high mass (6.2%), a passive solar direct gain low mass (0.4%), and a high thermal mass, including night flush (4.3%), direct and two-stage evaporative cooling (4.3%), and natural ventilation and fan-forced ventilation cooling (2.2%).
