Over the last four decades, the negative impact of the building industry and the growing environmental crisis have led architects to develop sustainable design strategies for a better-performing built environment. Building performance tools, which are commonly used at the end of the design process, are not integrated into the design synthesis. Therefore, there is no integration between the performance parameters. In the literature, there are many studies focusing on the seamless integration of energy and daylighting analysis. In contrast, the integration of natural ventilation and indoor airborne contamination analysis is hitherto understudied. However, natural ventilation can reduce buildings’ energy demand and carbon emissions. Also, natural ventilation can provide healthy environments for building occupants by reducing potential indoor airborne contamination. There is a need for an integrated approach and a digital workflow, specifically addressing effective natural ventilation and the removal of airborne contamination. This research addresses the urgent need for the integration of natural ventilation and contaminant dispersion analysis to the creative design synthesis/analysis processes and develops an integrated and hybrid analysis pipeline that couples parametric design, building performance simulation (CFD, daylighting, energy, and contaminant transportation), and model testing (wind tunnel) methods. The developed pipeline is implemented for a case study that consists of the shading device design of an office building. Implementing the pipeline, improving indoor air quality by providing adequate natural ventilation, and reducing the airborne contaminants while keeping the thermal loads and daylighting optimized is aimed.

A data-driven approach for predicting solar energy potential of buildings in urban fabric Duran, Ayça; Gürsel Dino, İpek; Department of Architecture (2022-7) Energy-efficient buildings that use clean and sustainable energy sources are urgently needed to reduce the environmental impact of buildings and mitigate climate change in cities. Buildings have great potential in harvesting solar energy by their solar exposure capacity. Developments in PV technologies also encourage the integration of PV systems into architectural applications. However, urban contexts can limit solar energy generation capacity of buildings by shading building envelopes and reducing availab...
A parametric design method for CFD-supported wind-driven ventilation Abbas, Günsu Merin; Gürsel Dino, İpek (2019-09-07) The negative impact of the building industry has brought a critical emphasis on the performance-related tools and processes of architectural design. The integration of design and performance simulation has the potential to extend the decision-making capabilities of the architects. Amongst a number of performance parameters, wind-related measures are generally problematic for the design phase, due to the computational cost of predicting wind behaviour, the complexity of the urban context and the constantly c...
Energy consumption of a day-occupied building utilizing phase changing material incorporating gypsum boards Akgül, Çağla; Gürsel Dino, İpek (null; 2018-09-14) In the architecture, engineering and construction industry, there is an urgent need for a shift to low-energy, sustainable buildings to address the environmental concerns, increase occupant comfort demands and lower the operational cost of buildings. In this direction, one of the most effective technologies is using PCM’s (phase change materials) as part of building envelopes. PCMs can increase building performance by increasing the thermal storing capacity of buildings by decreasing the heat transfer betwe...
An evaluation of material characteristics and hygrotermal performance of ecological thermal insulation materials for use in timber frame buildings Atılgan, Ilgaz Azra; Elias Özkan, Soofia Tahira; Department of Building Science in Architecture (2022-11-28) The effects of thermal insulation materials with toxic properties on users and on the ecosystem have led to the search for natural thermal insulation materials. The aim of this research was to study the properties of cork, coconut fiber, and cellulose-based ecological thermal insulation materials (ETIM) and to evaluate the hygrothermal behavior of the structure by using these materials in a sample timber framed structure. The physical, thermal and hygric properties of the selected ecological thermal insula...
Application of Artificial Neural Networks onBuilding Energy Estimation Altun, Murat; Ersöz, Ahmet Bahaddin; Akçamete Güngör, Aslı; Pekcan, Onur (null; 2017-12-11) Abstract -The decision makers in the building design stage need to give more importance for energy efficient solutions to improve the performance the building in its operational phase. In practice, they are expected to generate alternative designs in the early design stage and use complicated building simulation tools to estimate building energy use of these alternatives more accurately; however, this is a time-consuming procedure and it is difficult to evaluate different alternatives in the limited time of...
