“…Besides the limitation of external conditions, there is a limitation that is caused by the data source itself. Nowadays, it is quite common that local authorities have access to digital terrain models, including a detailed information about the roof geometry [52,53]. However, not all urban 3D models contain information on greenery.…”

Abstract:The global Sustainable Development Goals influence the implementation of energy development strategies worldwide. However, in order to support local stakeholders in sustainable energy development strategies and climate change adaptation plans and the implementation of policies, there is a need to equip local decision makers with tools enabling the assessment of sustainable energy investments. In order to do so, the aim of this study is to create a novel tool for the assessment of solar radiation (SOLIS) in ArcGIS. The SOLIS tool builds on the existing ArcGIS algorithm by including input data conversion and post-processing of the results. This should expand the group of potential users of solar radiation analyses. The self-filtering tool excludes surfaces that are not suitable for solar energy investments due to geometrical reasons. The reduction of the size of the output data is positive for technical reasons (speed of the calculation and occupied storage place) and for cognitive reasons (reduction of the number of objects necessary to analyse by the user). The SOLIS tool limits the requirement for users to insert three-dimensional (3D) models of roofs (with any geometry) and select solar radiation calculation periods. The highlight of this research is to develop the decision support tool for the assessment of solar radiation, which would reduce the requirements for potential users, in order to promote indicator-based assessments among non-Geographical Information Systems (GIS) specialists.

“…Numerous studies have been devoted to the problem of energy conservation in building engineering. For example, energy-saving issues of heating the buildings are discussed in [1][2][3][4][5][6][7][8][9]. One of the main ways to reduce heat losses in heating the buildings implies raising RSI-value of building envelope.…”

“…As a result, the calculation becomes impossible for air interlayers of building envelope where there is air motion. The authors of [8] use the finite volume method to calculate the thermal state of not just the building envelope but the entire building as well. To estimate heat flux through a multilayer building envelope, authors of [9] solved the non-stationary heat conduction problem taking into account diurnal variations of outdoor temperature and insolation.…”

“…Nevertheless, despite their simplicity, lumped model approaches do not allow one to obtain details about the building surfaces temperatures, necessary for simulating the frequent rapid variation of the thermal conditions occurring in buildings as well as for indoor comfort analyses [95]. If the flow field and the spatial domain to be discretized are a priori known, thermal network-based models could be preferable than more computationally expensive and complex building thermal ones [96]. For this reason, suitable detailed mathematical algorithms/models based on the thermal network approach have become more and more developed and are used to predict the whole building thermodynamic behavior and for analyzing the energy performance of building-plant systems [28,[97][98][99].…”

This paper focuses on the experimental validation of a building energy performance simulation tool by means of a comparative analysis between numerical results and measurements obtained on a real test room. The empirical tests were carried out for several months under variable weather conditions and in free-floating indoor temperature regime (switched off HVAC system). Measurements were exploited for validating an in-house simulation tool, implemented in MatLab and called DETECt, developed for dynamically assessing the energy performance of buildings. Results show that simulated indoor air and surface room temperatures resulted in very good agreement with the corresponding experimental data; the detected differences were often lower than 0.5 °C and almost always lower than 1 °C. Very low mean absolute and percentage errors were always achieved. In order to show the capabilities of the developed simulation tool, a suitable case study focused on innovative solar radiation high-reflective coatings, and infrared low-emissivity materials is also presented. The performance of these coatings and materials was investigated through a comparative analysis conducted to evaluate their heating and cooling energy saving potentials. Simulation results, obtained for the real test cell considered as equipped with such innovative coatings and material, show that for the weather zone of Naples a 5% saving is obtained both in summer and in winter by simultaneously adopting a high-reflectance coating and a low- emissivity plaster for roof/external walls and interior walls, respectively.
