    Analysis of Climate-Oriented Researches in Building
    (2021) Konstantin Verichev; Montserrat Zamorano; Cristian Eduardo Salazar Concha; Manuel Carpio
    Many factors and aspects of the construction and operation of buildings depend on climatic parameters and climatic zones, so these will be fundamental for adapting and mitigating the effects of climate change. For this reason, the number of climate-oriented publications in building is increasing. This research presents an analysis on the most-cited climate-oriented studies in building in the period 1979-2019. The main themes, the typologies of these investigations and the principal types of climatic zoning used in these studies were analysed through bibliographic and manual analysis. A broad spectrum of themes directly and indirectly related to climate and climatic zones and buildings was demonstrated. It was found that 88% of all climate-oriented investigations, to one degree or another, are within the scope of the general topic of energy conservation. A thorough understanding of all climate-dependent aspects will help in designing dwellings appropriately in different climate zones. In addition, a methodology that facilitates the establishment of a typology of climate-oriented research is presented. This typology can be used in future research in different scientific areas. It was also revealed that the climate zones of the National Building Codes of China, the USA and Turkey prevailed in the studies analysed.

    Bibliometric Analysis of Urban Coastal Development: Strategies for Climate-Resilient Timber Housing
    (2024) Andrés García-Ruiz; Manuel Díez-Minguito; Konstantin Verichev; Carpio Martínez, Manuel
    Urban development in coastal areas has become increasingly important due to the climatecrisis and its effects on sea level rise and extreme events, which increased the vulnerability of coastalzones. Therefore, it is important to analyze possible sustainable development techniques in urbanplanning and residential housing construction based on low-carbon footprint materials such astimber. These techniques should be capable of mitigating the effects of flooding and uncontrolledrises in coastal areas, as well as identifying normative and economic differences in their applicationin the Chilean context. For this purpose, a bibliometric analysis of 3882 articles selected from theWeb of Science database between 1987 and 2022 was conducted, allowing us to identify a range ofpossible solutions to be developed in the study area. This includes evaluating their potential fornormative application and a cost analysis of these solutions. In this regard, housing solutions suchas amphibious houses and houses on stilts are two types of flood-resistant homes that are gainingpopularity worldwide. Following the technical–economic analysis, it was observed that the solutionon stilts can be up to 50% more cost-effective to implement in Chile. However, both options offera promising solution to minimize the risks of coastal flooding and should be taken into account inthe urban planning of coastal areas.

    Dynamics of Changes in Climate Zones and Building Energy Demand. A Case Study in Spain
    (2021) Carmen Díaz-López; Joaquín Jódar; Konstantin Verichev; Miguel Luis Rodríguez; Manuel Carpio; Montserrat Zamorano
    In the current context of the climate crisis, it is essential to design buildings that can cope with climate dynamics throughout their life cycle. It will ensure the development of sustainable and resilient building stock. Thus, this study's primary objective has been to demonstrate that the current climatic zones for buildings in peninsular Spain do not represent the current climatic reality and are not adapted to climate change and the impact on the energy demand of buildings. For this reason, the climatic zones of 7967 peninsular cities have been updated and adapted to the RCP 4.5 and RCP 8.5 scenarios by using the data measured in 77 meteorological reference stations. The results obtained have shown that in more than 80% of the cities, buildings are designed and constructed according to an obsolete climatic classification that does not take into account the current or future climatic reality, which will significantly affect the thermal performance of a building and highlights the need to review the climatic zoning in the country. The results obtained can be extrapolated to other regions. The methodology defined in this work can be used as a reference, thus making an essential scientific contribution in reflecting on current capacities and the possibilities of improving the building stock.

    Influence of heating degree day calculation methods in designing the thermal envelope of buildings
    (2022) Konstantin Verichev
    Heating degree day is an essential parameter for estimation of energy demand and consumption in buildings. In the case of hourly temperature data availability, it is more appropriate to use the hourly method to calculate heating degree days. In the situation of reduced meteorological data, other methodologies must be selected for calculation. These methodologies include ASHRAE and UKMO methods. The aim of the present study is to analyse the effect of substitution in the heating degree day calculation method to modify building recommendations of current Chilean thermal building codes, maintaining the transmission heat losses through thermal envelope of buildings, in various geographical locations, with different climatic conditions. Analysing the data obtained from 165 meteorological stations, it has been discovered that there are significant differences in the geographical distribution of heating degree days calculated with ASHRAE and UKMO methods in desert areas, while heating degree days are similar in regions with a more temperate climate with both methods. When there is a significant frequency of days with large daily temperature amplitude, it is more advisable to use the UKMO method for the calculation of heating degree days. For all these reasons, new values of thermal transmittances have been proposed for the opaque elements of the thermal envelopes with the developed methodology. A reduction by up 65% of the values of thermal transmittances are required using UKMO method in desert areas and no variations are required in cold zones. The new values of thermal transmittances proposed will help to improve the energy performance of buildings and to achieve a better adaptation to the climatic conditions.
