Energy consumption of a day-occupied building utilizing phase changing material incorporating gypsum boards

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 between buildings and outdoor environment during both hot and cold seasons. In this work, the results of a simulation-based study of a test building with gypsum wall boards with micro-capsulated PCMs are presented. An energy model of a day-occupied office building in Izmir is developed, and a second model instance is generated that makes use of PCMs with different melting points. A comparative assessment is made to analyze the impact of PCMs on energy performance and carbon footprint. The main target is the identification of most suitable phase change material with referring melting temperature and latent heat capacity according to the climate conditions. Results point out the positive effects of phase change materials on energy performance and carbon footprint of a simple day-occupied office building.

Performance based façades: retrofit strategies for energy efficiency and comfort in existing office buildings
Jahed, Negin; Gürsel Dino, İpek; Department of Architecture (2018)
The building industry is faced with a vast stock of existing buildings that are not sustainable and suffer from poor conditions in terms of physical problems. Energy retrofitting of existing buildings is considered as a rational strategy to minimize buildings’ environmental impact in the long term. Standard building retrofits focus on prescriptive measures to comply with energy standards rather than occupant requirements. In contrast, the proposed performance-based retrofit approach focuses, primarily on in...
Economic assessment of the seismic retrofitting of low-cost apartment buildings
Arıkan, Mehmet Fırat; Macit, G (Informa UK Limited, 2005-07-01)
When structural retrofitting of buildings is required due to seismic safety considerations, building owners or government officials are faced with a crucial decision whether to demolish and rebuild their buildings, or retrofit them. Simple decisions based on fixed proportions, such as demolish and rebuild if retrofit costs exceed 40% of the replacement cost, may be misleading. A financial analysis should be carried out considering all the revenues and costs of the building during its life time. A low-cost r...

Due to global sustainability movements, environmental impact assessments are steadily accelerating in the Architecture – Engineering – Construction (AEC) sector. In order to achieve the 2030 and 2050 carbon targets, laws and regulations are published by governments and decision makers to reduce carbon emissions. Nowadays, transportation is the second-largest contributor to anthropogenic greenhouse gas emissions in the European Union, including Turkey. As a developing country, Turkey strives to catch not onl...
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...

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 da...
