Can different types of greenery improve the perceived value, safety, prestige, coziness, and aesthetics of multistory residential buildings?<br />To find the answer, two studies were carried out. In Study 1, participants filled in questionnaires designed to measure the perceived value,<br />safety, prestige, coziness, and aesthetics of a building. Every questionnaire was accompanied with one of four images of the same residential building, the only difference between them was the type of greenery present near the building. Participants were asked to evaluate the building in the image by filling in the questionnaire. A convenience sample of 238 university students (mean age 20, SD = 2) participated in the experiment. Study 2 was an internet-based survey in which participants were presented with four images of a residential building and were asked to identify the most cozy, most expensive, most prestigious, most safe, and most aesthetic building. The pictures were the same as in Study 1. A snowball sample of 356 respondents (mean age 30, SD = 11) participated in the survey. The results indicate that buildings with sophisticated greenery and plain grass greenery are perceived most favorably, while unkempt and chaotic greenery were found to be associated with worse overall perceptions and decreased perceived value of residential property. When creating green spaces near residential buildings, we recommend considering plain grass greenery as it is the most cost-effective solution and has a positive effect on the perceptions of residential property and its value.

Cost Of Energy

Korea relies significantly on imported fossil fuels to meet its energy needs. Moreover, about 50% of Korean residential buildings are apartment complexes. In this paper, the use of distributed generation (DG) technologies to serve the energy requirements for a typical Korean apartment complex is explored to reduce Korea’s dependence on fossil fuel and CO2 emissions. In particular, a series of sensitivity analyses is conducted using detailed simulation tools to determine the cost-effectiveness of DG systems to meet electrical and thermal loads of an apartment building in Daegu, Korea. The DG systems considered in the analysis include Photovoltaic (PV), Wind turbine, Microturbine, and Fuel Cell. The apartment complex is connected to the utility grid that with electricity typically generated using fossil fuels. It is found that a combination of the grid and Fuel Cell is the most cost effective approach to meet the electrical and thermal loads of the complex residential building with a cost of energy reduction of 12% compared to the grid only option.

This work addresses the effect of using thermochromic paints in residential buildings. Two different thermochromic paint types were considered: One that changes properties through a step transition at a certain temperature, and another that changes properties in a gradual/linear manner throughout a temperature range. The studied building was a two-floor villa, virtually simulated through a digital model with and without thermal insulation, and considering thermochromic paints applied both on external walls and on the roof. The performance assessment was done through the energy use for heating and cooling (in conditioned mode), as well as in terms of the indoor temperature (in free-floating mode). Three different cities/climates were considered: Porto, Madrid, and Abu Dhabi. Results showed that energy savings up to 50.6% could be reached if the building is operated in conditioned mode. Conversely, when operated in free-floating mode, optimally selected thermochromic paints enable reductions up to 11.0 °C, during summertime, and an increase up to 2.7 °C, during wintertime. These results point out the great benefits of using optimally selected thermochromic paints for obtaining thermal comfort, and also the need to further develop stable and cost-effective thermochromic pigments for outdoor applications, as well as to test physical models in a real environment.

Summary. Background: Running of built-in objects in residential houses can significantly worsen living conditions due to adverse effects of various chemical and physical environmental factors. Yet, sanitary and epidemiological standardization in terms of placement of non-residential premises in residential buildings is not sufficiently regulated, which leads to numerous violations when commissioning non-residential premises in residential buildings. In this regard, the question arises about legal acts regulating design issues and ensuring sanitary and epidemiological well-being when placing non-residential objects in residential buildings and constituting the basis for sanitary and epidemiological expert examinations. Materials and methods: We analyzed regulatory acts setting sanitary and epidemiological requirements for living conditions, placement of public facilities in residential buildings, and alteration projects in residential buildings and examined the archive of public complaints. Results: We established the absence of federal regulations requiring mandatory sanitary and epidemiological expert examination of alteration projects for public facilities built into residential buildings. A significant part of issues related to ensuring sanitary and epidemiological well-being of the population is determined by technical regulations on safety of buildings and structures rather than sanitary legislation. This is the reason why these regulations are included in the scope of accreditation of many inspection bodies of Rospotrebnadzor institutions. Executive authorities and customers of projects for placement of non-residential premises in residential buildings, assuming reconfiguration of built-in facilities, order a sanitary and epidemiological expert examination of alteration projects, rightly believing that elimination of nonconformities at the stage of a separate project will be the most cost-effective solution. Conclusion: It goes without saying that the most efficient solution that can help prevent deterioration of living conditions is a sanitary and epidemiological expert examination requiring amendments and additions to the current sanitary legislation on expediency of such an examination.

Most commonly, residents are always arguing about the quality of their high rise residential property. A growing number of high rise residential buildings in Malaysia with differing light well were designed by the structural design and planning since 15 years ago. This light well is defined as an intermediate space area between indoor and outdoor of the high-rise residential building. The questionnaire survey of three high rise residential buildings that have different sizes of the light well and building designed were conducted to make clear the occupants' evaluation about the real quality conditions of the buildings. As a result, the quality of light well is clearly satisfied and well managed by the property manager in their high rise residential buildings.

Aiming to lessen energy consumption and heating cost, this paper analyzes the effect of different types of window for residential building based on intermittent heating supply. The research results show that the type of window with a smaller heat transfer coefficient has higher energy consumption. Otherwise, the rate of temperature rising is slightly affected by the change of window with different heat transfer coefficient and window-to-wall ratio. Based on the economic and technical analysis, through changing the better window, energy-saving ratio can be arrived to 10.4%-16.8% and economic recovery period is 4.4-10.4 years. The research findings can be used for reference to thermal design in new residential buildings and provide improvement of building performance for existing residential buildings.

While the use of vinegar to fi ght against infections and other crucial conditions dates back to Hippocrates, recent research has found that vinegar consumption has a positive effect on biomarkers for diabetes, cancer, and heart diseases. Different types of vinegar have been used in the world during different time periods. Vinegar is produced by a fermentation process. Foods with a high content of carbohydrates are a good source of vinegar. Review of the results of different studies performed on vinegar components reveals that the daily use of these components has a healthy impact on the physiological and chemical structure of the human body. During the era of Hippocrates, people used vinegar as a medicine to treat wounds, which means that vinegar is one of the ancient foods used as folk medicine. The purpose of the current review paper is to provide a detailed summary of the outcome of previous studies emphasizing the role of vinegar in treatment of different diseases both in acute and chronic conditions, its in vivo mechanism and the active role of different bacteria.
