The most basic way to keep comfortable indoor environments for a building’s occupants and save energy for space heating and cooling in residential buildings is to insulate the building envelope. Among the building materials to be used, thermal insulation materials primarily influence thermal performance. In particular, the type, thermal conductivity, density, and thickness of heat insulator, are important factors influencing thermal insulation performance. We investigate the design status of residential buildings which were designed in accordance with the building code of Korea and selected the type of thermal insulation materials applied to the walls of buildings. The present study aims at measuring the thermal conductivity of thermal insulation materials used for building walls of residential buildings. In this study, after collecting the design documents of 129 residential buildings, we investigated the type and thickness of insulation materials on the exterior wall specified in the design documents. As the thermal insulation materials, extruded polystyrene (XPS) board and expanded polystyrene(EPS) board are used the most widely in Korea when designing residential buildings. The thickness of thermal insulation materials applied to the exterior wall was 70mm, most frequently applied to the design. We measured the thermal conductivity and the density of XPS board and EPS board. When the density of XPS and EPS was 30~35 kg/㎥, the thermal conductivity of XPS was 0.0292 W/mK and it of EPS was 0.0316 W/mK.

This paper introduces the present situation of existing residential building energy saving reconstruction of Anshan area, the result of the analysis is that the renovation of retaining structure is the key of the reconstruction of existing residential buildings of Anshan. Exterior wall area ratio of the total area of the building envelope accounts for quite large, so transformation of exterior wall is the key. Energy saving wall approach divided into external wall insulation and exterior insulation. Analysis of energy-saving measures by the external wall insulation, and the external wall of a residential district in Anshan city and analysis of thermal insulation and energy saving renovation case, better energy-saving effect, energy saving measures of external economy more external insulation, the region has provided the reference and basis transformation of external wall energy-saving residence building.

The purpose of the work is to analyze fire prevention measures in structures of external walls with facade thermal insulation and plastering, as well as to analyze the features of their arrangement, taking into account the experience of neighboring countries. The application of exterior wall designs with facade thermal insulation with plaster finish, as well as problems related to their fire hazard, are substantiated. The works are analyzed to investigate the problems of fire safety of exterior wall structures with facade thermal insulation and plastering, as well as hinged facade systems. The types, design features, purpose and functions of fire belts and framing of window (door) openings made of non-combustible materials, which are arranged in exterior wall designs with facade thermal insulation and plaster finish, are considered and analyzed. The role of floor fire belts and the framing of window (door) openings made of non-combustible mineral wool boards have been established. It is concluded that the use of structures of the exterior walls of residential buildings with facade thermal insulation with a combustible insulation and plastering significantly increases their level of fire danger. This danger will depend both on the properties of the individual materials (in particular the insulation), and on the design features of the entire thermal insulation system and the building as a whole. For plaster systems of thermal insulation of facades, the rapid spread of fire on the higher and lower floors of the building is a big threat. Frequent causes of fire of thermal insulation systems of external walls is the tipping of fire from a window opening of a building as a result of intense fire indoors. Materials of decorative and protective finishing of walls should meet requirements of normative documents on designs of external walls with facade thermal insulation and plaster finish, and their constructive execution will depend on the height of the building and functional purpose of the object. Fire-fighting measures, foreseeing in the construction of exterior walls with facade thermal insulation and plastering, intended to ensure their fire safety during the time necessary for the safe evacuation of people from the building, the arrival of units of fire and rescue units and extending the fire throughout its distribution.

Problems and disadvantages of some technical solutions concerning modern heat efficient exterior walls are considered herein under experience of engineering, construction and operation of residential and civil buildings in the Republic of Bashkortostan. Special attention is paid to defects in engineering and erection of three-layer walls, and functioning principles of all components of the wall are strictly fixed. Recommendation to increase maintenance-free service life by meeting special engineering requirements are given herein. Effect to increase buildings heat insulation is achieved by: reducing heat loss through separate enclosing structures and heat insulating shells of the building thereby enabling to reduce thermal power requirements; improving heat acceptability in rooms by decreasing rate of radiative and convective heat exchange in outer surface of enclosures; reducing environmental pollution due to air emissions reduction. Exterior wall insulation is the important element of the building heat balance. Many researchers in this field currently focus on analysis of series of residential buildings with different number of storeys made by engineering solutions for exterior walls to increase heat homogeneity thereof. Subject: main engineering solutions for heat efficient exterior walls. Objectives: three-layer wall constructed of masonry units; exterior three-layer wall within 121u panel series; three-layer wall of “Ventilated façade” system; façade heat insulation with plaster on lath; wall made of load-bearing structural insulating materials. Materials and methods: calculation of reduced total thermal resistance in exterior walls. Results: one of the most efficient methods to meet specific heat-shielding performance requirements is to increase heat homogeneity of the exterior wall. Conclusions: in the short term structural components of three-layer exterior walls are to be upgraded according to construction rules and regulations SNiP 23-02-2003 “Buildings Heat Insulation” thereby enabling the engineering solutions to meet the appropriate norms and rules.
