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.

Daylighting improves users’ experience in visual comfort, aesthetics, behaviour and perception of space and plays an important part in enhancing the health and wellbeing of occupants inside a dwelling. However, daylighting design is challenging for high rise living since configuration of multiple apartments together often results in deep plans and wrongly oriented apartments with poor daylighting. Melbourne considered as the most liveable city in the world has witnessed a boom in high rise apartments in recent years, where bedrooms were designed without windows or with one small opening. Previous studies indicated that one out of two apartments in Melbourne’s central business district (CBD) failed to provide daylighting in the bedrooms. This has led to amendments in planning policy with the aim of providing access to daylight in all habitable rooms. This paper investigates the daylighting conditions in apartment buildings using field measurement and daylight simulations. Daylight levels in 12 apartment units in Melbourne CBD were measured. Additionally, daylight simulations were conducted to identify ways for optimizing light levels in standard layouts. The field measurements showed that daylighting levels were insufficient in one third the apartments due to the presence of deep floor plates and external obstructions. The results from the daylight simulations showed that window to floor area ratio (WFR) of approximately 30% is required for achieving acceptable daylighting levels in bedrooms that have south orientation.
