“…These studies have shown that vernacular buildings can achieve acceptable comfort standards throughout much of the year by passive means alone [5,6,[17][18][19]. In some cases, indoor air temperatures remained almost constant with no need for air conditioning, except during winter season [5,6,[17][18][19]. The results presented in these studies support the arguments that passive strategies can be feasible for contemporary buildings and that they could contribute towards reducing buildings' energy demands for heating and cooling.…”

Contribution of Portuguese Vernacular Building Strategies to Indoor Thermal Comfort and Occupants’ Perception

et al. 2015

Solar passive strategies that have been developed in vernacular architecture from different regions are a response to specific climate effects. These strategies are usually simple, low-tech and have low potential environmental impact. For this reason, several studies highlight them as having potential to reduce the demands of non-renewable energy for buildings operation. In this paper, the climatic contrast between northern and southern parts of mainland Portugal is presented, namely the regions of Beira Alta and Alentejo. Additionally, it discusses the contribution of different climate-responsive strategies developed in vernacular architecture from both regions to assure thermal comfort conditions. In Beira Alta, the use of glazed balconies as a strategy to capture solar gains is usual, while in Alentejo the focus is on passive cooling strategies. To understand the effectiveness of these strategies, thermal performances and comfort conditions of two case studies were evaluated based on the adaptive comfort model. Field tests included measurement of hygrothermal parameters and surveys on occupants' thermal sensation. From the results, it has been found that the case studies have shown a good thermal performance by passive means alone and that the occupants feel comfortable, except during winter where there is the need to use simple heating systems.

“…Their very low environmental impact is thanks to the little energy needed during the building stage and the thorough recyclability of almost all of their building materials, which are often completely natural and compatible [5]. In addition, raw-earth constructions perform well thermally [11][12][13][14][15][16][17]; allowing the buildings good thermal insulation capacities and thermo-hygrometric comfort of the indoor environments, including sound insulation [18]. In this way, raw-earth constructions have been encouraged during recent years, especially in those countries where they could be an easily accessible and economically attractive resource due to the climatic and economic conditions, , joining well to the local traditional architecture.…”

Cob Construction in Italy: Some Lessons from the Past

et al. 2010

Raw earth is a construction material unknown to most people. Nowadays, raw-earth constructions are an area of growing interest, both for rescuing the heritage and for a rediscovered environmentally friendly building and eco-sustainability material. However, because raw-earth constructions are a forgotten technique, we find problems of a lack of skilled people at all levels in this area, from designers to masons, as well as problems of how to carry out compatible conservation works on earthen heritage. This paper tries to fill the gap for a peculiar historic earthen building technology, namely cob (or bauge), which is present in Macerata in the center of Italy. Results are presented on regaining possession of the material and constructional aspects and their initial structural resources, and guidelines are given on how to improve the manufacturing process to reuse the cob technique for construction and for how to accurately work on it for a compatible and sustainable conservation.

“…Referring to thermal energy performance, traditional single-layer masonry presents critical situations in winter due to poor insulation: research based on on-site monitoring of traditional stone buildings has shown that stone envelopes are not able to provide sufficient thermal comfort without heating systems, even if they keep the internal temperature more stable than lightweight ones [2]; another study [3], again based on on-site investigations, has shown that thermal transmittance values of traditional stone envelopes range from 1.25 to 1.70 W/(m 2 ·K), far higher than the limit values imposed by the Italian energy-saving regulations [4]. As a consequence, previous research has stressed the need to improve the energy efficiency of existing buildings characterized by traditional stone envelopes, and has assessed the effects of insulation in terms of thermal comfort and energy consumption [3,5,6].…”

Building in Historical Areas: Identity Values and Energy Performance of Innovative Massive Stone Envelopes with Reference to Traditional Building Solutions

Abstract:The intrinsic nature of local rocks shaped the features of built heritage in historical centers. The resulting building culture is part of the cultural heritage itself, and must be considered when building in such areas, while it is essential to solve the issues related to traditional constructions' weaknesses. Nonetheless, the potentialities of massive stone envelopes, particularly the importance of thermal inertia, have contributed to redefining the language of contemporary architectural culture. Nowadays, although the trend of employing thin stone cladding panels is prevalent, thick stone envelopes are gaining a renewed importance. Previous literature demonstrated that mixed building technologies or massive stone envelopes coupled with load-bearing framed structures are able to meet comfort and safety requirements and to guarantee the integration of new constructions in the consolidated urban landscape, avoiding historicist approaches. This research, through the analysis of case studies, aims to describe innovative building solutions developed by contemporary architectural culture, comparing them with traditional stone masonry walls. Moreover, thermal energy performance of such building solutions is assessed through dynamic yearly simulations. Results show that these solutions are technically and architecturally suitable to build in historical centers, because they can express urban cultural identity and guarantee good energy performance and users' comfort.
