Densification Of Single And Two-Family Houses Considering Green Space And Mobility

The question of future energy-efficient creation of living space is becoming more and more important in many cities due to limited space availability and simultaneously increasing settlement pressure. Against the background of the desired space, ressource and energy efficiency, cities are therefore steadily-focusing on internal development and densification. Especially single and two-family houses, which represent over 60% of all residential buidlings in many cities offer a great potential for sustainable densification and also show a high level of refurbishment needs. However, more than 90% of these buildings are privately owned. So in order to encourage a sustainable urban development, the existing densification potentials need to mobilized by addressing the owners directly to convince them for the measures to mobilize the given potentials.

The project BONSEI! (Optimal use of existing stock – energy-efficient implementation of refurbishment!) has already developed a corresponding consulting service for addressing post-compression measures. It has been shown, that qualified and personal advice is an important source of inspiration for owners to mobilize post-compression potentials. Another essential aspect in the implementation of post-consilidation measures is the preservation of the quality of life. Therefore, the aim of the research project BONUS (optimal use of stock – strengthen the environment) is to integrate the topics of sustainable mobility, greening and open space design into the BONSEI! post-compaction consultation. The implementation of this consulting offer in Vorarlberg and Salzburg as well as the development of a transferable operator model for generating a municipal Austrian-wide added value, are further targets of BONUS.

Reintegration of Karachi Port through Sustainable Adaptive Reuse of Abandoned and Underused Buildings

During the second industrial revolution, the Indian subcontinent was ruled by the Britishers and they developed Indian industries in such a way that they were dependent on British capital goods. To transport the goods railway and maritime routes were constructed in the mid and late nineteenth century. It was because of the importance of the seaport that the Britishers conquered the city and started developing Karachi port. Due to the port, the area of Karachi grew from a small fishermen's village to a bustling metropolitan city.

Karachi port still is the center of main logistic transportation of the country, but some of the buildings of heritage value are neglected on this site. After the 9/11 tragedy in the US, due to security reasons, Karachi port was restricted to the public. Now, the situation is better, and the port can be reintegrated and make accessible for the public through sustainable adaptive reuse of the abandoned or underused buildings. Karachi is a congested city with few places for recreation, reintegrating this site can open opportunity for tourism at the same time showcasing the industrial heritage of the city.

This paper wants to articulate the potential of industrial heritage. But the latter is in Pakistan not yet recognized as part of a heritage discourse. The port offers a rich case study due to its layered history and its variety in typologies.

Advancing Circular Economy in the Existing Building Stock: a methodology to support building characterisation for sustainable refurbishment design

The lack of standard practices and platforms for assessing refurbishment strategies towards Circular Economy (CE) and their impact in global warming constitutes a challenge for the decarbonization of existing building stock. Incorporating data and feedback from designers and practitioners since early design stages is important to feed a multi-criteria dynamic process with multiple dimensions, which must be assessed under a life cycle perspective. To tackle this issue, this paper introduces a new methodology to support the implementation of tailored refurbishment strategies for increased recovery, reuse and recycling of construction materials. The final objective is to build a methodological framework for sustainable refurbishment design in a BIM environment, which aims to facilitate standardized practices in the construction sector, regarding CE, with a positive impact in the mitigation of global warming and the decarbonization of the building stock. To test the development of this methodology, a case study building in Lisbon, corresponding to a 1919-1945 archetype is analysed, making use of its BIM model, where BIM standardization criteria and circularity indicators are discussed, in order to be implemented as a Plugin for Circularity.

Lifelong Learning of Property Managers in Enabling Sustainable and Energy Efficient Residential Buildings: Experiences of CARE Project in Tampere Region

The existing building stock causes 40% of the total energy consumption in the European Union. The high energy consumption together with ageing buildings put strong pressure on renovation of buildings and lowering of CO2 emissions. The Directives on Energy Performance of Buildings (EPBD) and Energy Efficiency (EED) were established to urge and steer the activities in the EU member countries.

There are about 90,000 housing companies in Finland. They consist of 1,7 million apartments and 2,7 million residents, which makes housing companies a significant energy consumer. Around 50% of the building stock in Finland was built between 1960s and 1980s. The average level of technical building systems is decent. Measures are still needed to tackle the increasing maintenance backlog and energy consumption objectives.

Management of housing companies consists of the general meeting of apartment owners and a board elected by the general meeting. In addition, a vast majority of housing companies have a professional property manager whose role corresponds to CEO. The property manager’s expertise plays an essential role in planning and execution of maintenance and energy efficiency.

The role of the property manager calls for multidisciplinary competencies and continuous learning. The CARE - Resource efficient caretaking of residential buildings project implemented flexible courses and training for property managers to enhance their technical understanding of energy efficient renovations and retrofit of new energy solutions.

The Potential of Unused Railway Areas

Railway transportation faces many of the issues that are related to standard brownfields – due to changing technologies and industries, more effective systems (of traffic control in this case) and evolving needs many of the areas are actually no longer necessary for proper function of the railway. That is especially prominent in the case of railway stations, where a significant number of the stations use just a portion of their available tracks, buildings and areas (for example for unloading or repair). The remaining areas are sometimes sporadically used, but more effective and conscious management of the station could fairly easily lead up to the release of these areas for another, more useful function for both the city and the station. This paper will explore the differences between “standard” brownfields and unused railway areas like the typical ownership structure, particular location within the city and the effect station has on the city structure, composition and topography of the areas or the fact that railway areas are most often never really fully abandoned and they do continue to serve in some, albeit diminished capacity. Paper also aims to map out how much of the railways areas are underused or unused in Czech Republic (country with highest rail network density in the world). This paper will then recommend the best ways to use and revitalize them and it will show some successful examples of revitalization projects from all around the world.
