Highly insulated envelope or external insulation systems are being applied in recent energy saving buildings to reduce the heat loss through envelope. Internal insulation systems are applied to most apartments in Korea because they are inexpensive and convenient to construct. However, the internal insulation systems have poor performance due to the heat bridges through structures such as slabs. The external insulation systems have better thermal performance because the heat bridges through the structure are rarely formed. But it has problems regarding the external insulator separation due to strong winds, spread of fire due to insulator combustion in case of fire, formation of heat bridges through the connectors between structure and external insulation. To supplement the weaknesses of the internal and the external insulation systems, a sandwich insulation system has been suggested. In this study, the thermal performance of sandwich insulation system for apartment buildings was evaluated according to two type of the form-tie material.

The article is devoted to one of the actual problems concerning the current state of the facades on apartment buildings in residential districts in Kiev - videoecology. The main purpose of the article is to determine the degree of visual aggressiveness of multistorey residential buildings in Kiev. It also investigates the problem of finding the optimal criteria for creating an ecologically healthy and friendly inhabited environment in the capital city of Ukraine. The modern visual environment in the capital is contaminated, not only because of the increasing numbers of promotional billboards, but also because of the contemporary architecture of high-rise buildings such as office buildings, apartment buildings. Their composition is usually based on a simple description of a rhythm. There are also repetitions of the end parts of buildings in ?lowercase? buildings, which are high-rise buildings that alternate with nine or identical apartment groups. It creates a sense of oppressive monotony and leads to psychological and visual fatigue, especially when these repetitions are the only pattern the eye perceives. In the article a theoretical block of ecological-aesthetic criteria is defined, which must be met by the modern architecture facades of multistorey residential houses in Kiev.

By the recent COVID-19 situation, people stay more time in their home and abatements on noise between neighbouring units are increasing. Heavy/soft impact sound is one of the major noise sources in high-rise apartment buildings. Standardized heavy/soft impact source is known for having the most similar physical and subjective characteristics with real impact sound such as a child running, jumping and an adult walking. The single number quantity on the rubber ball was standardized. A classification scheme for rubber ball impact sound needs to be standardized. Several studies on subjective responses were conducted on rubber ball impact sound in various situations. In this study, subjective responses on the rubber impact sound and real impact sound were compared. The subjective experiment was conducted in the listening chamber which is furnished similarly to the typical living room of Korean apartment buildings. In the experiment, rubber ball impact sounds recorded in the real apartment building and real impact sound recorded in the mock-up building were presented through a sub-woofer and multi-channel loudspeaker system. Subjective responses were collected with an 11 points SD scale.
