A methodology to support the decision-making process for energy retrofitting at district scale

download link

The need to accelerate energy retrofitting and integrate renewable energies in the built environment sector has been recognized by the European Union and its member states, with many policies and directives already in place. However, compared with single building retrofitting, there are no established approaches for energy retrofitting at district and urban scales, in part due to the complexity of the computational problem and the decision-making process. In the transition towards low-carbon cities, new approaches to assess a variety of energy efficiency and renewable energy generation solutions for large building stocks at acceptable computational costs are needed. Moreover, stakeholders require flexible and adaptable tools to support the selection of the most cost-effective retrofitting scenario. In this context, this study proposes a new methodology for the planning of energy retrofitting at urban scale.

From Tradition to Modernity: Innovative shadings to save energy in residential architecture of Bodrum, Turkey

download link

There is much to be learned from traditional buildings while improving them for contemporary needs. With the change of climatic, structural and physical conditions of buildings as well as inhabitants with different life styles, energy consumption in such buildings have increased. At the same time, contemporary buildings are being built generally without traditional principles and without attention to efficient energy use. In the current concern for sustainability, there is a pressing need to develop and install shading devices that can help transform them to energy efficient buildings.
This paper presents innovative architectural shading ideas for reducing the energy demand of the residential buildings in Bodrum developed using building energy simulations. First, a traditional house in Bodrum has been analysed from the point of view of energy consumption. Then a prototype house has been developed according to the simulation results of the reference objects. Local, window, and roof shading elements have been developed for this prototype in order to measure the energy reduction effect. As a conclusion, their effects on energy saving has been described and the potential of introducing the shading devices in the new buildings has been discussed.
