    Abstract: In this paper an overview on the inclusive spatial design tools providing equal access to waterfront landscapes for tourists living with disabilities will be given. The focus is on close-to-natural areas which are popular because of their recreational potential. These areas present special natural and landscape values, and mostly are ecologically vulnerable. In these important ecological surroundings human presence and landscape values must be harmonized. Environmental conditions, legal requirements and the economic situation can limit the opportunity for comprehensive access, but keep disability in mind while designing and maintaining these sites is a potential to provide wider access to the waterfront tourist destinations. We are about to present model solutions keeping the environment totally or mostly in its original, natural condition, but allowing recreational activities in the site at the same time.

    Acoustical Properties of Contemporary Mosques14-30en [1.52 MB - PDF]EPA-02446-00007-0020

    Abstract: Religious buildings are important for many communities because of their representation of different beliefs. In such structures, the sense of individuality or unity and togetherness are created according to variable worship activities; these different uses have also different acoustical requirements. In order to create the desired feeling in the space at the required time, rooms should be evaluated in terms of acoustical conditions. In the study, it is aimed to investigate the objective parameters of sound of the main prayer hall of the Bedirye Tiryaki Mencik Mosque, which was built recently in Manisa (Turkey). It is one of the modern examples of mosque architecture in Turkey. The structure differs from other contemporary examples with the design approach and construction technology. The mosque was built by using prefabrication technology for the entire structure. The acoustical evaluation of this recent example by comparing the recommended values of objective parameters shows that the building has balance between architectural and acoustical design.

    Keywords: Mosque acoustics; contemporary mosque design

    Bionics in architecture31-42en [2.50 MB - PDF]EPA-02446-00007-0030

    Abstract: The adaptation of the forms and phenomena of nature is not a recent concept. Observation of natural mechanisms has been a primary source of innovation since prehistoric ages, which can be perceived through the history of architecture. Currently, this idea is coming to the front again through sustainable architecture and adaptive design. Investigating natural innovations and the clear-outness of evolution during the 20th century led to the creation of a separate scientific discipline, Bionics. Architecture and Bionics are strongly related to each other, since the act of building is as old as the human civilization – moreover its first formal and structural source was obviously the surrounding environment. Present paper discusses the definition of Bionics and its connection with the architecture.

    Abstract: The study assessed allocation, criteria and allotment effectiveness of performance risks in Build- Operate-Transfer (BOT) transportation infrastructure in Nigeria using Lagos Infrastructure Project (LIP) as a case study. LIP is the only BOT-procured tolled road that has attained ‘operate’ stage of BOT cycle in Nigeria. It revealed that more operating risks were actually allocated to the concessionaire than the grantor and most of the risks were preferred retained by the allottee. Significant fraction of the risks was effectively allocated between the concessionaire and grantor except those that involve close interface between participants. While grantor rated nine risks high and seven risks very high; the concessionaire assessed nine risks to be high and five risks to be very high; the grantor rated the effectiveness level to be seventy three per cent and the concessionaire assessed it to be sixty four per cent. The study recommended that the evolving knowledge from Lagos Infrastructure Project (LIP) should be documented to guide future BOT transactions in Nigeria.

    Abstract: This study investigates the possibilities of various development areas (transport, energy, building) to make the cost-efficient realisation of high-profile investments, and organising and holding international sports events possible. Using a case study, the paper introduces development routes based on the evaluation of environmental and economic perspectives. The current research introduces the investment characteristics based on the development of the Hungarian building, energy and transport sectors for the 2017-2030 period. The main criterion is the integration of ‘circular economy’. For sectors which operate with high material and energy consumption, the consideration of circular economy principles may prove to be important for sustainable development. Through planning highvolume sports and worldwide events, the usual development strategy for traffic systems focuses on public transport and rentable vehicles (f. e. electric scooter, or bicycle) which can decrease CO2 emissions via modern technological solutions. Regarding the buildings, sports arenas and related facilities, besides the existing low-carbon solutions, the functions of buildings must be expanded and their usage prolonged. The management of waste left after the life cycle is expended has to be pre-planned. These are the options for making the sector’s GHG emissions decrease apart from circular tenders, which can be further combined with SMART energetic solutions.
