“…These standards require an energy analysis made under semi-stationary conditions, simulating the building energy demand through average values of environmental temperatures, solar radiation and wind velocity. For that reason, this kind of investigation shows the characteristics connected to the stationary features of climatic phenomena, as shown in many studies [11][12][13][14]. Consequently, in order to provide a more detailed analysis, it is possible to use a more complex calculation tool, represented by a dynamic software that allows us to analyze the effects of climatic variations over the time.…”

Abstract:Nowadays it is possible to employ several software packages to evaluate building's energy performance, each of them based on a different calculation code, with different boundary conditions in terms of environmental temperature, solar radiation, wind velocity and relative humidity. In this contribution, a comparison between two calculation codes, taking into account different types of buildings, has been carried out. In particular, a semi-stationary calculation code and a dynamic one have been employed to determine energy demands of three different building's types: an old building, a house and a flat. Analyzing semi-stationary conditions (consequently simplified environmental conditions), a software which applies the UNI TS 11300 standard has been considered. This standard defines the procedures for the national implementation of the UNI EN ISO 13790. Furthermore, in order to consider the environmental conditions variation, a well-known dynamic software has been used.

“…In the case of solid brick walls, used on upper storeys, similar values of damping and lag of the thermal wavelength can be found, due to the nature of the material. Hence, thermal inertia also plays an important role [39]. These high values of thermal inertia allow greater thermal stability, which, in principle, would be a desirable feature, especially in climates with temperature ranges close to comfort.…”

Adaptation Strategies and Resilience to Climate Change of Historic Dwellings

Historic city centres have a large amount of dwellings in Europe, which were built to provide a comfortable shelter with the absence of mechanical means. The knowledge of climate responsive design strategies can play a significant role in reducing the energy demand of extant buildings, paving the way for its sustainable development in the face of the rising threat to its occupants of climate change. The residential architecture, developed, in most cases, in dense urban centres, was built using both available materials and traditional and academic construction technologies. This paper thoroughly investigates the extant urban conglomerate in Cádiz and analyses, in a qualitative and quantitative manner, which bioclimatic design strategies were applied and the city's adaptation for future climate scenarios. The results indicate that historic housing in Cádiz is creatively adapted to the local natural conditions by means of a combination of climate responsive strategies, and there is significant scope for improvement in the ongoing response to global warming.

“…To confirm such value, studies based on dynamic simulations and on-site monitoring have proved that massive envelopes are able to ensure a considerable reduction of indoor thermal discomfort during summer [12,13]. Other researchers [14] have shown that the difference in terms of energy demand in buildings characterized by low-inertia walls compared to high-inertia ones is as high as 20% for cooling energy demand and equal to almost 10% in terms of heating energy demand, with high-inertia envelopes allowing energy savings. Furthermore, it has been stressed that it is impossible to design energy-efficient buildings using only an U-value-based approach and that the role of thermal inertia, i.e., the positive effect of thermal capacity, appears to be relevant in particular for moderate climates [15].…”

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.
