To the question of improving energy-saving and environmental characteristics of urban buildings

Abstract

A new structural material for the production of ventilated facades (ventilated fences)-granulated blast furnace slag, which has high structural, thermal and adsorption properties, allowing to signifi cantly increase the energy-saving and environmental characteristics of ventilated fences and, accordingly, facades of buildings and structures. Developed by the innovative design of ventilated facade (ventilated fencing) based on blast furnace slag, allowing the clear air of the street from a signifi cant part of nitrogen oxides, sulphur oxides, oxides of carbon, soot particles and dust, to reduce the amount of heat delivered to the building in summer and heat loss in winter, which greatly improves the environmental and economic performance of buildings.

Modeling of property management process at territorial level

“…It means that the objects of management are projects and investment projects in the case of signifi cant changes and modernization of real estate. Accordingly, the technology and organization of work should be based on the composition and sequence of work on preparation and implementation of projects (including investment), taking into account the characteristics of various phases of life cycle [2,3,12]. Regardless of the type of project, all of them are carried out in accordance with the following universal sequence of work within a single technological cycle.…”

Development of technology for reducing the technogenic impact of sugar factories on the environment of localities

“…One of the focal points of the environmental policy of the country is production ecologization, i.e. development and implementation of technologies providing ecological balance in nature, circulation of substances and energy, preventing environment pollution [1,10,11,12]. Sugar industry is one of large agribusiness industries processing plant raw materials.…”

“…Based on the study it can be concluded that sugar industry enterprises signifi cantly affect the environment in the areas nearby, therefore, some environmental protection measures to reduce the impact on the environment shall be taken The main ones among them are: • introduction of a maximum possible number of recirculation water systems (at least 7) with minimum water discharge into waste water systems which enables reduction of fresh water consumption and waste water amount by half; fl ume -washing sludge in a settling tank which allows 85% reduction of waste water discharge in relation to beet weight; • application of methods of not natural biological treatment which will result in the reduction of areas for waste treatment facilities (fi lter fi elds) and release of 50-80 ha of fertile soils; • implementation of saturation machines of a new design to increase the saturation gas disposal which will provide 30% reduction of gas consumption in the process line; • application of membrane technology of defecation which will reduce saturation gas consumption twice; • application of sugar refi nery technology using polyelectrolyte without saturation gas application which annually reduces CO 2 consumption by 5 mln m 3 for 1 sugar refi nery mill [9]. It is also necessary to arrange an ecological control system designed to prevent negative impact on the environment [7,9,10,11]. Therefore, to reduce technological impact of sugar industry on water and air, it is necessary to implement new technologies for core production and for waste water treatment, introduce industrial environmental control and implementation of the environmental management system taking into consideration modern requirements.…”
