Speech Title: Membranes over façades to improve residential building efficiency: The Mediterranean context Abstract: In the EU-28, only 3% of residential building stock is “A” rated on energy efficiency (EPDB), of which 80% will be renovated and 20% replaced, until 2050; in line with EU guidelines and targets, for a 90% reduction in GHG emissions, compared to 1990s values. In 2016, EU-28 households accounted for 24.5% of the total (final) energy consumed: 79.2% from indoor and water heating (94.1% from petroleum derivatives), and 0.3% from cooling (100% electric sources). The latter indicator has a potential growth up to 8.7%, based on households’ electricity consumption of 2015, 785 tWh/a, considering Global Warming predictions and air-conditioning market growth, supported by technological improvements and consequent low-interest fares from price-cutting and stable economic growth promotion. The idea proposed in this research is to use tensile membranes to wrap residential buildings, adding a semi-opaque ventilated façade solution over external walls, mimicking the traditional qualities produced by the material on Sun exposed streets in Southern Europe. This architectonic proposal can embrace fashion design or interior decoration trends adding color, patterns, or imaging on aging buildings. This research aims to contribute to residential stock efficiency by reducing the energy bill costs, GHG emissions, maintenance operations, and to improve comfort. At the same time, it aims to exceed the solution’s investment need and be capable of generating revenue. The Solution presents reliable economic results as assessed by the Profitability Indicator (Energy Savings minus Investment), evaluated on a 25-year frame: favoring both inland and coastal cities, improving its average performance by 42%; although, on a strictly financial perspective, is not advisable in islands' seaside

 

Plenary Speaker

Assoc. Prof. Marina Rynkovskaya Peoples' Friendship University of Russia (RUDN University), Russia Dr. Marina Rynkovskaya is an associate professor at department of Architecture and Civil Engineering and the head of Alumni department of Engineering Academy at Peoples’ Friendship University of Russia (RUDN University). She obtained BSc and MSc degrees in Civil Engineering in 2002 and 2004 respectively at Peoples’ Friendship University of Russia (RUDN University). Since 2003 she had worked as a project engineer in industry for 10 years and defended her PhD thesis in Structural Mechanics at Moscow State University of Railway Engineering (MIIT) in 2013. Since 2006, she has worked at RUDN University (including as an associate professor since 2014). The main research topic concerns analytical methods of stress-strain analysis of spatial/shell structures, especially helicoids, and she is a member of the international association for spatial structures (IASS). She is also involved in several research projects such as optimization of free-form roofs (in collaboration with CentraleSupelec, France) and stress solution for elastic/elastic FGM discs (in collaboration with Beihang University, China). She has the Honorary Diploma of the Rectorate of the RUDN University for active scientific and pedagogical activity (2016), the best teacher award of the Moscow City Professional Competition of Pedagogical Excellence and Public Recognition in the nomination "Young Teacher of the University - 2012" . Speech Title: Studying the shape of a helical ramp Abstract: The main purpose of the presentation is to clarify the classification of helicoids and to introduce several types of helicoids to engineers in terms of geometry, stress-strain behavior and exploitation parameters for the practical tasks. Mathematically helical ramps are usually designed in the shape of a right helicoid which is well-known among civil engineers and designers, while mechanical engineers also know evolvent and convolute helicoids and use them for screws. The presentation mostly focuses on the civil engineering and architectural helical structures such as ramps. It is shown that designers generally do not pay proper attention to the way the surface for a ramp can be formed from mathematical point. However, different types of helicoids (and ramps as final structures) show different stress-strain and buckling behavior. The review of existing classifications, methods of calculation and differences in geometry of all five types of ruled helicoids are presented. The clear classification which can be used by both mathematicians and engineers is shown, along with the most appropriate methods for calculation. The geometry and stress-strain behavior comparison of several types of helicoids is done in order to find forms which are the most rational for application to ramps and screw elements of buildings.
