Designing Urban Building Blocks Around Solar Planning Principles

Abstract

This paper aims to determine the optimum geometry of the building blocks in order to ensure the viability of specific building integrated solar systems (BISTS, BIPV) in the current urban fabric. The research starts with an analysis of the fabric's geometry and characteristics as they are defined by law, and through a literature review, explores the possibilities of building integration of active solar systems in the urban fabric, whilst similar attempts of research are reported and analyzed. For the main body of the research, a simple set of rectangular building blocks is created, and through the configuration of some parameters the most viable geometry is determined, in order to have the most possible insolation on the buildings' roofs and facades. The parameters are the ratio between the length and the width of the building blocks, the width of the streets between them, the height of the buildings and the geometry of the buildings that can be accommodated in the proposed building blocks. The buildings' geometries are determined in ways that they could accommodate apartments in a viable way in order to create sustainable neighborhoods. The insolation, which reflects the potential for the building integration of active solar systems, is calculated with the use of digital modelling. The ultimate aim of this work is to present and analyze the limitations and problems of the integration in the urban fabric, and propose research-based solutions, which could establish a guide that gives guidelines for building integration of active solar systems on a neighborhood level. Further research will determine the ratio of the building's usable area/solar system's area if the geometry of the building is optimal, and the findings will be applied to the actual urban web of Cyprus in order to be optimized. It will also be investigated whether the solar urban design reduces the ability of the existing or potentially existing urban fabric to cover the needs of the city into residential units.

Long-term planning and development for urban and regional inclusion, safety, resilience, and sustainability. Insights from Singapore

“…It evaluates and grades a building's environmental impact and sustainability performance (Vardopoulos, 2019b). The Green Mark allocates points to projects according to their performances in the categories of energy effi ciency, water effi ciency, environmental protection, indoor environmental quality, and other green features and innovations, which are all aspects well-addressed consistently in the wider scholarly literature (Savvides and Vassiliades, 2017). Based on the points allocated, a project was awarded Green Mark Certifi ed, Gold, Gold+and Platinum ratings.…”

Determinación de variables edilicias presentes en morfologías del Área Metropolitana de Mendoza para la eficiencia energética

“…La morfología urbano-edilicia ha sido ampliamente analizada por sus efectos sobre el comportamiento energético edilicio, disponibilidad solar en fachadas norte y techos, ganancias solares, microclima urbano, confort térmico exterior, dirección y velocidad del viento, contaminantes y calidad del aire (Aboelata, 2020;Bakarman, & Chang, 2015;Bourbia, & Awbi, 2004;Huang et al, 2021;Martinelli, & Matzarakis, 2017;Mesa et al, 2011;Ruggeri et al, 2020;Schulte et al, 2015;Shareef, & Abu-Hijleh, 2020;Vartholomaios, 2017). La temática es de impacto para planificadores y diseñadores preocupados no solo por la calefacción de espacios activa y pasiva, calentamiento de agua para uso doméstico y generación fotovoltaica, sino también por la rehabilitación profunda del parque edilicio Colucci et al, 2017;Huang, & Li, 2017;Li et al 2020b;Savvides, & Vassiliades, 2017;Sharifi, 2019;Shi et al, 2021;Wolff, 2014;Zhang et al 2019).…”

The Study of Architectural Geometry and Shape in the Energy Balance of Glazed Roofs

“…It can be seen that the above studies primarily focused on the shape design of PV modules [31,32], performance optimization [36], and performance prediction methods of BIPV or PV arrays [35,38,39]. In addition, Savvides, A., and Vassiliades, C. focused on community-level planning and examined the relationship between blocks and solar radiation in different combinations of simple building blocks (Figure 4) [34]. Pacheco-Torres, R. et al conducted studies on building morphology.…”
