Optimization of Hybrid DHS to Reduce Primary Energy Consumption by the Means of Thermal Energy Storage

One of the alternative to minimize the energy demand of the building sector is the implementation of the district heating system (DHS). This research focuses on the integration of thermal energy storage systems nto the DHS for regulating the energy demand and reducing the peak demand load. Thermal storage further allows the DHS to store the surplus energy harnessed from renewable technologies. Another challenge to tackle in this study is the development of an accurate model to predict the detailed energy demand profile of the DHS.

Energy Efficiency and Marketability of Buildings

Energy efficiency of buildings have drastically developed in last decades. However, a number of barriers such as marketability challenges, high capital cost, and unappealing visual aesthetic caused against widespread adoption of these buildings. Especially in the residential sector, building buyers and decision makers typically place higher value on visible amenities rather than invisible benefits such as low energy bills. This study hence explores the relation between buildings energy-efficiency and their marketability parameters.

Coupling of Building Energy Simulation and CFD

The energy budget of a building is significantly impacted by its neighborhood environment. A common drawback of the current building energy simulation (BES) tools such as EnergyPlus, Ecotect, TRNSYS is the neglected impact of the surrounding microclimate on the convection heat transfer at the target building facades. This study therefore links BES with a microclimate CFD model to better resolve the influence of the surrounding neighborhood on the heat transfer, occurring in the exterior surfaces of the target building. The initial results of the coupled model show a significant improve in the accuracy of the current annual energy calculation of the buildings.

Wind-driven and Natural Ventilation Potential of Traditional Buildings

Passive strategies in ventilation developed over thousands of years have shown a great potential for the reduction of residential energy demands, which are often underestimated in modern building’s construction. In particular, as a cost-effective passive strategy, wind-driven ventilation through windows has a huge potential in the enhancement of the indoor air quality of buildings while simultaneously reducing their cooling load. The functionality and adaptability of a common historical Turkish architectural element (Cumba) in modern buildings – to improve the wind-driven ventilation – was studied using an experimentally validated microclimate CFD model.
