How to understand healthy housing?

Relevant experts define healthy housing as: on the basis of meeting the basic living requirements, highlighting the healthy elements, meeting the physiological, psychological and social needs of residents with the concept of healthy and sustainable living, and creating healthy, safe, comfortable and environmentally friendly high-quality housing and communities for residents. In other words, a healthy house should be a house that can keep the residents in good condition physically, mentally and socially. Specifically, a healthy house can be directly interpreted as a living environment embodied in residential buildings and residential areas, which can include not only physical values related to the house, such as temperature, humidity, ventilation, noise, light, air quality, etc., but also subjective psychological factors, such as plane space layout, privacy protection, visual field landscape, sensory color, material selection, etc. And return to nature, pay attention to health, society and so on.

Energy-saving building refers to a low-energy building that follows the basic methods of climate design and energy saving, and is designed after studying the zoning, groups and units, building orientation, spacing, solar radiation, wind direction and external space environment. Its main indicators are: building planning and plane layout should be conducive to natural ventilation, and the greening rate should not be less than 35%; The spacing between buildings should ensure that each household has at least one living space to get 2 hours of full-window sunshine in cold days.

Energy-saving buildings have five characteristics: First, they consume less resources. Design, construction and use should reduce resource consumption;

Second, high performance and high quality. Structural materials should have sufficient strength, durability, envelope structure, thermal insulation and waterproof. ...

Third, reduce environmental pollution. Use low-pollution materials and clean energy;

Fourth, long life;

Fifth, recycle more.

Nine problems to be considered in saving buildings

The environmental problems of architecture include the utilization of topography, greening, water body and environmental sketches.

The orientation of the building.

The shape of the building, including shape coefficient, space utilization, frame and floating board, etc.

The concept of moderate consumption should be advocated for the problem of building area.

For the sound, light, heat, sunshine, ventilation and other physical environment problems of buildings, natural lighting and ventilation should be used as much as possible.

Water-saving appliances should be selected for water-saving problems in buildings and the utilization of reclaimed water.

The land-saving problem of buildings should increase the depth and narrow the width of houses as much as possible; Use strip houses as much as possible; Choose the appropriate building floor.

Building solar energy utilization, active solar residential building, passive solar residential building.

The decoration of the building is simple, which can reflect the feeling of home.

The concept of healthy housing in China is very general, which is generally boasted by the construction companies themselves.

Healthy housing should meet certain technical indicators, such as: healthy housing should have indoor fresh air exchange and supplementary equipment during the use of air conditioning in winter and summer; The outer window should be made of double-layer or insulating glass; The heating system should be energy-saving, with household metering and room temperature regulation system; Perfect community medical facilities, cultural and entertainment facilities.

In 200 1 year, the National Housing and Housing Engineering Center compiled the Technical Essentials of Healthy Housing Construction (200 1 trial version), which stipulated the construction of healthy housing from the aspects of living space, air quality, thermal environment quality, acoustic environment quality and water environment quality.

There are only two healthy houses under construction in Beijing-Beijing Olympic Peak Garden and Jindi Greentown.
