<abstract xmlns="http://www.w3.org/1999/xhtml">Water safety plans are public health related risk management plans, covering the entire water supply system, based on the theorem of prevention. Risk evaluation is fundamental for setting up a risk management system. A modified risk assessment equation is shown which takes into account the severity of consequences of the hazard an accentuated way. This method was used successfully n a number of practical water safety system applications. Water safety plans are practical tools for water utility operators which can be applied in different fields of operation, from water quality improvement of decision support tool of developments. The role of the distribution system and its operation is clarified from water quality deterioration and risk mitigation point of view.</abstract>

WATER SAFETY PLANS FROM THE ENGINEER’S PERSPECTIVE

<abstract xmlns="http://www.w3.org/1999/xhtml">The purpose of this work is to determine the pre-exponential factor (A) and the reaction activation energy (E) of decomposition reactions that are needed for Fire Dynamics Simulation (FDS) using Derivatograph Q 1500D. The materials we investigated: Pine Wood Board (PWB), Multilayered Parquet Board (MPB), Particleboard Core (PBC) and Oriented Standard Board (OSB).</abstract>

DETERMINATION OF THERMAL DECOMPOSITION REACTION CHARACTERISTICS (A, E) OF WOOD SAMPLES FOR FIRE DYNAMICS SIMULATION

<abstract xmlns="http://www.w3.org/1999/xhtml">One of the major causes of delays in construction sites belongs to the delays in delivering materials. This paper introduces the integrated Building Information Modelling (BIM) model combined with a supply chain and a controlling system, along with its efficiency for alleviating the negative effects of delays caused by a lack of materials on construction sites. So, firstly the concept of feed-forward control is discussed as a prevention feature in a monitoring system. Then the integrating BIM model with a supply chain is introduced. Finally this case study has shown how the enhanced BIM model can incorporate the feed-forward control in order to decrease the risks of delays caused by a lack of materials in construction. Moreover, this case study might be used as a decision support system for managers to prevent a construction site from future delays by providing valuable information about the required materials in advanced</abstract>

INTEGRATED BUILDING INFORMATION MODELLING (BIM) WITH SUPPLY CHAIN AND FEED-FORWARD CONTROL

<abstract xmlns="http://www.w3.org/1999/xhtml">The building energy sector is not immune from the physical impacts of climate change and must adapt. The impacts are more gradual, such as changes to heating and cooling demand. Disruptions to the energy system can also have significant knock-on effects on other critical services. To improve the climate resilience of the building energy system, governments need to design and implement frameworks that encourage prudent adaptation, while the private sector should assess the risks and impacts as part of its investment decisions. Comprehensive studies covering the impact of climate change on the building energy sector are still lacking, though some regional and sector-specific analysis exists. The buildings sector has been examined in more depth than most, with studies finding that temperature increases are expected to boost demand for air conditioning, while fuel consumption for space heating will be reduced. For the follow-up research activity the question has been posed: How can the climate changing trends and the building sector rising energy demand meet in urban environment? As an outlook this present paper can be defined as an ex-ante document in the DENZERO Project towards generating the Hungarian Climate Severity/Energy Index.</abstract>

CLIMATE PARAMETERS IN BUILT ENVIRONMENT FROM ENERGETIC POINT OF VIEW – TOWARDS CLIMATE SEVERITY INDEX IN HUNGARY

<abstract xmlns="http://www.w3.org/1999/xhtml">The Concrete Canoe Competition has been organized second time in Hungary in 2013. The main point of the competition is to design and create a floating concrete object with specified dimensions, which does not contain statically rigid frame. A speed-trial is also part of the contest. The team of Szent István University, Ybl Miklós Faculty of Architecture and Civil Engineering attended both the first (2012) and the second (2013) competition. In both years the main part of designing and creation of the canoe was under the direction of employees of Building Materials division of the Insitute. Building a concrete canoe proved to be a complex challenge. Knowledge of different engineering fields was required to solve the task - questions about material properties, hydrodynamics, statics, technologies were needed to be solved. Present paper introduces the authors’ experience, investigations, and means of realization of the concrete canoe.</abstract>

CONCRETE CANOE: A COMPLEX CONCRETE TECHNOLOGY

<abstract xmlns="http://www.w3.org/1999/xhtml">The article introduces a method to evaluate and develop quality of sustainable mobility planning in European cities. This tool has been worked out by a European Consortium of experts representing 14 countries in Europe. The author - as the Hungarian member and auditor of the Consortium - participated in the project working as an auditor in four Hungarian cities, leading them through the process of the QUEST-method and helping the cities to develop a systematic way of planning sustainable mobility. In the article the process will be shown, advantages, lessons learned, drawbacks and possible future development of the method will be explained.</abstract>
