What is a green house? More important than a house is health.

Green housing is a new housing model designed and built based on the principle of sustainable development between man and nature and the principle of efficient utilization of resources, which can make the material and energy system inside and outside the house virtuous circle without waste and pollution, and realize energy self-sufficiency to a certain extent.

The most striking feature of this kind of residence is its pro-nature, that is, in all activities such as planning, design, construction, operation, maintenance and management, demolition and transformation of residential buildings, nature is managed and cared for from beginning to end, and the negative impact on the natural environment is controlled to a minimum as far as possible to achieve harmony between residential areas and the environment.

The so-called "green" of "green building" does not refer to the three-dimensional greening and roof garden in the general sense, but represents a concept or symbol. It refers to buildings that are harmless to the environment, can make full use of environmental natural resources, and do not destroy the basic ecological balance of the environment. It can also be called sustainable development building, ecological building, returning to nature building, energy-saving and environmental protection building, etc. The indoor layout of green buildings is very reasonable. Minimize the use of synthetic materials, make full use of sunlight, save energy, and create a feeling of being close to nature for residents.

What characteristics should a green house have?

In addition to the basic functions of traditional houses such as shelter from wind and rain, ventilation and lighting, green houses also have special functions of coordinating the environment and protecting the ecology. Therefore, the construction of green housing should follow the ecological principle, embody the principle of sustainable development, and carry out according to the specific requirements different from traditional housing in planning and design, construction methods and material selection. According to the "Technical Guidelines for Green Ecological Residential Quarters" being studied and formulated by the Housing Industrialization Promotion Center of the Ministry of Construction, there are roughly the following standards to measure the quality of green residential quarters:

L, it is widely open in physiology and ecology;

2. Use harmless, pollution-free and naturally degradable environmental protection building materials;

3. According to the principle of open and closed cycle of ecological economy, there is no waste and pollution in ecological engineering design;

4. Reasonable three-dimensional greening is helpful to protect and stabilize the ecology of surrounding areas;

5. Clean energy is used to reduce the energy consumption of residential operation and improve the self-sufficiency level;

6. Rich in ecological culture and artistic connotation.

What is the national standard for green housing?

Green Building Evaluation Standard GB/T50378-2006 issued by the Ministry of Construction of China and the General Administration of Quality Supervision, Inspection and Quarantine defines "green building" in the national standard for the first time, and also emphasizes that it must meet the relevant standards such as land saving, energy saving, water saving, material saving, indoor lighting, sound insulation, ventilation and air quality.

This standard puts forward requirements for the indoor environment quality of residential buildings and public buildings respectively. Especially in the residential building standard, it highlights four requirements for indoor environment: lighting, sound insulation, ventilation and indoor air quality, which are closely related to people's daily life. From low to high, the main indicators are divided into three levels: control items, general items and preference items. According to the general project, the green building must meet the following requirements:

Each house has at least 1 living space to meet the requirements of sunshine standard (the national standard "Code for Planning and Design of Urban Residence" has the following requirements for urban sunshine standard: no less than 2 hours on cold days and no less than 1 hour on winter solstice. ), when there are four or more living spaces, at least two living spaces meet the requirements of sunshine standards. Bedroom, living room (hall), study room and kitchen are provided with external windows, and the room lighting coefficient is not lower than the current national standard. Bedroom, living room (hall) and kitchen should be provided with external windows, and the area ratio of windows to the ground should not be less than 1/7. When a house has more than 1 bathroom, at least one bathroom has an external window.

Specifically, the standards for green houses are as follows:

The noise during the day does not exceed 45 decibels.

This house can be naturally ventilated.

Ensure energy saving while ventilating.

Indoor environmental pollution control

Per capita green space is 2㎡.

The water saving rate is not less than 8%

The garbage sorting recovery rate is 90%
