The relationships of good housing arrangement are apparent. Throughout history, house construction has often illustrated not only on how to solve a problem, but also on how to acquire another. Protection against climate impact in the form of winter's biting cold, ice-storms, and a penetrating rainfall has been a prerequisite for survival at all levels. The risks of moving into a new housing structure indicate that moisture problems in homes are known for a long time [17, 3]. The turn of the century's speculative housing with moisture, lice, congestion, lack of daylight, and fresh air created the foundation for the massive renovation of our housing stock carried out in the twentieth century. Healthy housing for all became one of the most important driving forces in modern architecture. Resource demand in the form of energy conservation was the first environmental issue in the building that attracted much attention. Partly, as a result of unilateral energy conservation, the "sick houses" and a new insight into the health issues must be included in the program work.

critical components than today's "advanced" mechanical systems that have often been found to cause more problems than they solve. Also, we can accept greater temperature fluctuations between day and night or summer and winter; the systems can be further simplified. Through balconies, terraces, and beautiful outdoor places and gardens for work and relaxation, and by designing the transition zone from the outside to make it easy to get out, the architect can make it more attractive to stay out for more hours a day. It also facilitates the weathering of clothes, textiles, and furniture. Healthy housing is created by direct natural lighting where sunlight means a lot for health and for well-being. Studies show the adverse health effects of windowless rooms. The architectural task is to achieve good daylight without the temperature rushing in, thus creating a need for cooling, reducing the requiring sizeable mechanical

Building materials and installations must also be chosen for health reasons. Although there is no scientifically related relationship between ill health and the delivery of volatile organic matter from building materials in the low doses that occur outside the industrial environment, there is every reason to choose documents that issue a minimum of emissions [15]. Several case studies show that self-emission of building materials caused health problems such as eye irritation from paints or building boards. A significant problem is the pollution caused by chemical reactions when exposed to moisture or high alkalinity. In the Chemicals Inspectorate's list of pollutants, all substances are classified according to allergy-producing substances, substance causing mucous membrane inflammation, etc. This list can be compared with the product information that the material suppliers are required to provide for hazardous health substances included in the product. Through architectural solutions, the need for emitting materials such as glue, filler, and joint pulp can be significantly reduced, sometimes eliminated. Low-frequency noise and vibration caused by ventilation systems can be overcome partly by choosing a quiet ventilation system, such as self-sufficiency, partly by a well-chosen assembly of the unit, careful damping, soundproofing of the fan room, making

ducts, fans and pads prefabricated, and adequate noise suppressor installed [16].

The starting point for any housing or urban renewal plan is of course that the city is not automatically maintained and updated in consistent with new social needs. Therefore, the first comprehensive identification of the content of the urban renewal concept could be that it should include all activities aimed at such maintenance and updating—modernization of the city. The modernization of big cities has primarily been achieved by adding new parts that have divided the existing obsolete parts into a different role so that either consciousness was not of the utmost importance that they were outdated or the new position and role enabled economic transformation and updating. The idea was not particularly interested in the existing city but instead created a modern city outside, which in a brief time moved the city center's functions, i.e., where the demand for the model was most excellent, to the new urban area [18]. The loopholes that have the existing city were thereby reduced to a partial problem, an isolated barrel tide problem, which was not an obstacle to the city's participation in a general industrial sustained social development. It is essential to have an urban renewal through growth because it focuses on the particular issue today and must take place without application of the dynamic and the disassembly factors, where, the rise has historically created. If the city subject is restricted and the definition of urban renewal is conservative so the focus will be on activities aimed at transforming maintain, update, modernize—the already existing parts of the city, then become one of the first significant examples of urban renewal Paris's modernization under Napoleon HI and Haussmann.
