Occupant Satisfaction

The analysis of thermal comfort in buildings, energy consumption, and occupant satisfaction is crucial to influencing the architectural design methodologies of the future. However, research in these fields in developing countries is sectorised. Most times, the standards to study and assess thermal comfort such as ASHRAE Standard 55, EN 15251, and ISO 7730 are insufficient and not appropriate for the geographical areas of application. This article presents a scoping review of published work in Colombia, as a representative case study, to highlight the state-of-the-art, research trends, gaps, and potential areas for further development. It examines the amount, origin, extent, and content of research and peer-reviewed documentation over the last decades. The findings allow new insights regarding the preferred models and the evaluation tools that have been used to date and that are recommended to use in the future. It also includes additional information regarding the most and least studied regions, cities, and climates in the country. This work could be of interest for the academic community and policymakers in the areas related to indoor and urban climate management and energy efficiency.

Design Variables

In building design, the decision-makers should not focus only on energy efficiency as a single objective but indoor environmental quality indicators, such as thermal comfort, daylight usage and so on, should also be considered as a part of building performance. The building performance can be ensured by determining the proper performance indicators and the variables during the design. In this context, a weighted (among the objectives) multi-objective cost function was proposed, for the optimisation of energy, thermal comfort and daylight usage of a case study archetype design, through the selected design variables, considering the base architectural design principles as well. A typical social housing archetype design was determined as the case study to apply the proposed approach. The window sizes are optimised for each orientation simultaneously, for a temperate-humid climatic region. The results were evaluated in terms of improvement potentials of energy, thermal comfort and daylight performances, and the dominant values for the window sizes for each facade. According to the results, the optimised scenario achieved an 11.42% reduction in primary energy use equivalent to 181.24 kWh/m2a, a 4.52% reduction in a predicted percentage of dissatisfied with 9.12%, and a reduction in lighting energy of 4.94% equivalent to 21.17 kWh/m2a. These reductions verify the possibility to achieve higher performances on each criterion.

Heritage buildings are significant historical and architecture added value, which requires deep and precise preliminary brainstorming when considering upgrading or retrofitting these valuable buildings. In this study, we opted to highlight some passive design architecture interventions to improve the thermal comfort and the required cooling energy for buildings. The Murabba Palace in Riyadh was selected as a case study. DesignBuilder software was used to evaluate the energy performance of ten passive architectural design alternatives throughout different seasons in an attempt to improve the energy performance and thermal comfort of heritage buildings. The ten passive design scenarios encompassed double low-E glass, double reflected glass, double low-E glass and double wall with an air gap, double low-E glass and double wall with thermal insulation, double low-E glass and double wall with lightweight thermal insulation, double low-E glass and double wall with sprayed foam insulation, double reflected glass and double wall with an air gap, double reflected glass and double wall with thermal insulation, double reflected glass and double wall with lightweight thermal insulation, and double reflected glass and double wall with sprayed foam insulation. The results show that using double low-E glass and applying a double wall with polystyrene thermal insulation can enhance the thermal comfort inside the building and reduce the energy performance and CO2 emissions to 17% and 9%, respectively.

O estudo do clima urbano, especificamente do comportamento do seu campo térmico, constitui-se em um dos grandes problemas socioambientais para as populações residentes nessas áreas. Dessa forma, o presente trabalho analisa os efeitos dos diferentes tipos de cobertura de solo nas condições do campo térmico do Campus I da Universidade Federal da Paraíba, localizado na cidade de João Pessoa, PB. As medições da temperatura do ar e umidade relativa foram realizadas em dois períodos distintos (seco e chuvoso), utilizando-se data logger Hobos em seis pontos representativos da área de estudo. O Índice de Thom foi utilizado para analisar o nível de conforto térmico nas escalas diária e horária e o tipo de cobertura de solo de cada ponto analisado foi definido considerando oito classes, de acordo com a percentagem de vegetação e de materiais permeáveis e impermeáveis existentes no entorno do ponto. Os resultados do trabalho permitiram caracterizar o micro clima local e identificar alterações no ambiente provocadas pelo adensamento de construções, além de fornecerem dados para fazer sugestões no sentido de minimizar esses efeitos através da manutenção da arborização remanescente da Mata Atlântica. As análises quantitativas e qualitativas dos dados revelaram diferentes condições micro climáticas na área de estudo que foram modificadas substancialmente em função da cobertura do solo. As áreas com alta concentração de materiais impermeáveis mostraram nível de desconforto térmico bastante elevado no período de maior demanda atmosférica, que ocorre entre 11 e 15h. Palavras-chave: Clima urbano, Campo térmico, Índice de Desconforto de Thom   Analysis of Conditions of Thermal Comfort in Urban Environment: a Case Study in University Campus  ABSTRACT The study of urban climate, specifically the behavior of their thermal field, it constitutes one of the great social and environmental problems for people living in these areas. In this way, the present study analyzes the effects of different types of ground cover in the thermal field of the Federal University of Paraíba, Campus I which is located in the city of João Pessoa, PB. The measurements of air temperature and relative humidity were carried out in two distinct periods (dry and wet seasons), using data logger Hobos in 6 representative points through study area. Thom’s discomfort index was used to analyze the thermal comfort level in daily values into one-hour time scale through University campus. The types of ground cover for each analyzed point were classified into 8 classes according to percentage cover in vegetation and permeable and impermeable materials. The results allowed to characterize the local microclimate, as well as identify environment changes provided by urban crowding, and to suggest actions to reduction of these effects by maintaining Atlantic forest biodiversity. The quantitative and qualitative data analysis showed that the different microclimatic conditions at experimental area were substantially due to soil cover changes. The areas with high concentration level in waterproof materials showed high level of thermal discomfort just in the period with highest atmospheric demand which it occurs from 11 to 15h.   Keywords: Urban climate, thermal comfort, Thom’s index

The Times

In this era of globalization, there is an interesting phenomenon in urban development. Many parts of the city are chaotic in their development, but there are cities that are fixed, unchanging. Semarang city is one that has not changed due to the times. Semarang city was planned by Herman Thomas Karsten as a modern city starting in 1916. Herman Thomas Karsten (1884-1945) is a Dutch architect who has worked as an architect and city advisor since his arrival in Indonesia in 1916. Karsten's most complete work is located in Semarang City. Karsten's work covers the town planning of Semarang city and the architectural design of buildings. History shows the fact that architectural works that survive are those that have a local aspect in their design concepts. This fact also happened to Semarang city. Through a literature review on city theory, architecture and local aspects, and by taking the case of Semarang city as a modern city by Karsten, it can be seen that the application of local concepts in Karsten's work, as well as the relationship between local concepts and primary elements of city in Karsten's works. This study aims to interpret Karsten's concept of thought, explore all local aspects in urban planning, which influence Karsten, and reveal the dominance of local aspects found in the case study. This research provides benefits for the scientific development of architecture, and provides new insights to the academic community about the importance of local aspects to architectural work. This research makes it clear that a city will survive if its town planning applies local concepts. As for the community, this research contributes to helping the creation of a new built environment for cultural heritage artifacts through a good architectural conservation work strategy.

In 2017 abandoned on the dusty attic for at least twenty years the valuable fungi collection was discovered. After the investigation, it turned out that counting 2159 specimens collection is forgotten and long wanted life work of professor Andrzej Nespiak, a significant polish mycologist (1921-1981). The decision was easy: the collection must be restored, digitalised and secured for the future. These processes met many difficulties on all possible levels. The project consisted of three main stages: cataloging, conservation, and digitisation. Cataloging stage showed how valuable the collection is. Almost every specimen has very detailed information about location and habitat like hosting plant name (even specific names for bark or dead branches for fungi growing on wood), soil type for terrestrial ones, phytocoenosis, etc. Almost every specimen has a microscopic drawing of spores with dimensions attached. Collection dates mostly mention only month and year of collection. The big problem cataloging was chaotic naming. No name contains the names of authors. Different grammatic forms of specific epithets of the same species are used. There are a lot of species names and lower taxa names which do not exist in Index Fungorum. The main challenge was to set one standard of conduct. Conservation stage was very important. Despite the attic was quite dry, many specimens were damaged. A small part was exposed to water and slightly infected by mold. Some were damaged by insects due to high temperatures in summer. All specimens were covered in dust. In the beginning, the whole collection was dried and frozen to stop mold and insects. Later mold was removed and all specimens were transferred to the new envelopes and boxes. All stationery used in herbarium is archive quality, acid-free. During the digitisation stage, all specimens were photographed with labels and all additional information and drawings. The whole project brought many challenges and required from staff a lot of commitment and deepening knowledge to properly select solutions.

Purpose According to the “strategic focus and future orientation” principle of the integrated reporting (<IR>) framework, <IR> should provide information useful to support investors in assessing the future financial performance of organizations. This study aims to support the operationalization of this function by improving the forward-looking orientation of the integrated report. Design/methodology/approach Basing on the backward- and forward-looking disclosure in <IR> and the dynamic resource-based view (DRBV), this study develops an explorative case study building a quantitative simulation model based on an integrated report. Findings This study provides useful insights into how operationalizing the <IR> “future orientation” and obtaining more quantitative information on the organization’s capacity to create value in the future by applying DRBV and quantitative simulation modeling. Research limitations/implications The article presents one case study to explore the method suggested to improve the <IR> forward-looking orientation. Additional case studies applying the same research design should be certainly useful to refine the method. Practical implications Supporting the <IR> forward-looking orientation, this study provides additional information for the decision-making process of investors, thus contributing to the efficient and productive allocation of capital. Originality/value Few studies have investigated forward-looking information in integrated reports, highlighting the existence of an “information gap” referred to such disclosure. Overcoming these previous results, the study provides useful insights on how to improve the <IR> forward-looking orientation.

<p class="Keywords">The project to build the Great Mosque of Algiers is underway. This will be the largest mosque in the world, after the mosques at Mecca and Medina. Trying to reflect the Algiers’ context, this project refers in his architectural design to Almoravid (11th century) influences, through an abstract way of interpretation. The aim of this paper is to explain this mode of interpretation by using a new approach. This approach combines both syntactic and semantic categories of the architectural object. It consists on the architectural syntax which tries the combination of space syntax and figurative abstract process. It is through a comparative study between the former mosque of Algiers: Djama’ al-A’dam (AH 490/ AD 1096–1097) and the future great mosque of Algiers that will explain this abstract way of interpretation, which seems more expressive than figurative.</p>

Building performance represents the most important factors for the successfulness and evaluation ofbuildings efficiency in meeting the requirements, expectations, and acceptance of the inhabitants. As a result, itindicates the success or failure of the architectural design experiment in the building. The research deals with themost important aspects of the performance and factors affecting the efficiency of the building, highlighting theindicators of thermal comfort assessment and types of standards and the most important software used in. Thus theresearch focuses on the possibilities of performance simulation programs in raising the standard of living and try toreduce the gap between the technological developed world and the local experience, through the development of acomputer model which simulate the local environment. The aim is introducing the possibilities of simulationcomputer models to help in providing a better environment according to thermal comfort standards of the building’soccupancy. The experimental method came in three levels, the analytical level (to analyze the case study), thestandard level (to return the results from the previous level to a benchmark manual for comparison), and the designlevel (to propose design alternatives to solve the problems derived from the previous two levels). The use of programs such as Rhino, Grasshopper, RayMan, leads to perform a specific function in the simulation processaccording to each level of application. The most important outputs of the research are the great effeteness of thearchitectural form on temperature change and thus access thermal comfort by comparing the basic form in addition tofive other design alternatives. Additionally, the total radiation temperature varied each time, thus varying the degreeof thermal comfort. The optimal shape was selected from the range of models as the closest one to the human thermalcomfort zone.
