Quelle est la relation de développement entre la conception active et la conception passive?
At the end of the last century, active design and passive design in the architecture industry developed in parallel, with active design occupying a dominant position. But after decades of development, people have gradually realized that passive design produces more significant effects and is also easily accepted by the market.
La nouvelle technologie et l'équipement contredisent-ils le concept de salles passives?
The use of new technologies and equipment is mainly aimed at improving the efficiency of equipment from the perspective of optimizing supply to meet the requirements of reducing building energy consumption. However, this approach ignores the control of building energy consumption demand. In fact, demand and supply coexist in both directions.
Quelle est la relation entre les maisons passives et la conception passive d'économie d'énergie?
Passive house is a type of passive energy-saving design, but it is different from the broad concept of passive energy-saving buildings. Passive house is a design category in passive design that has more scientific and specialized attributes, with design standards, systems, and methods.
Le système technologique est-il utilisé dans les méthodes et techniques passives passives passives passives?
Pas entièrement, la conception de la maison passive préconise une stratégie technique qui priorise la passivité et la compléte avec des méthodes actives.
Quelle est la relation entre les salles passives et les méthodes de chauffage traditionnelles?
A standard passive room does not have heating facilities at all, and can maintain a comfortable indoor temperature of 20 degrees by relying solely on the residual heat of household appliances and other indoor appliances. It reduces heating energy consumption to 90% energy saving through passive means, and its significance is not a difference in numbers, but a complete change in heating methods, a process from quantitative change to qualitative change.
Quelles sont les directives techniques pour les maisons passives en 06?
Firstly, enhance the performance of the external enclosure system; Secondly, increase the airtightness of buildings; Thirdly, utilize a fresh air system with heat recovery.
La technologie passive des maisons peut-elle être utilisée pour la restauration et la rénovation des anciens bâtiments en 2007?
Secondly, this is a problem that architects both domestically and internationally are facing. For buildings with historical value, only partial renovation can be carried out; For old buildings with practicality but no historical value, they can be renovated according to the passive house standard. At present, there are cases of construction in European countries with good implementation effects.
L'entretien passif de la maison est-il compliqué?
Thirdly, no, the technology used in passive housing is visible and tangible: for example, residents can replace the filter of the fresh air system once a year themselves. Passive houses do not have heating systems, only heat recovery fresh air systems and fresh air heating coils, so they are houses with very simple HVAC equipment. Passive houses require much less equipment to operate and maintain than regular houses. Of course, the quality of the windows and heat recovery fresh air systems used in passive rooms is very high, and the production of these products will naturally adopt high-tech.
Quelle est l'étanisme d'un bâtiment?
Fourthly, it refers to the ability of the building envelope structure to prevent air infiltration. The airtightness of passive ultra-low energy buildings is measured by the ratio of the amount of air that permeates through the building envelope structure in one hour to the indoor volume when the indoor and outdoor pressure difference is 50Pa.
Pourquoi améliorer l'étanchéité des bâtiments?
Fifthly, as the saying goes, 'the bigger the needle hole, the bigger the hole, the stronger the wind.' However, poor air tightness in buildings can lead to wind and air leakage, resulting in a significant loss of heat. Improving the air tightness of buildings to a scientific value can effectively reduce building energy consumption and improve indoor cleanliness.
Comment l'étanchéité de l'air du bâtiment 11 est-elle assurée?
Sixièmement, afin d'assurer l'étanchéité de l'air, il y aura une couche hermétique sur le côté intérieur de la structure de l'enveloppe du bâtiment.
Quelles zones ne peuvent pas être forées lors de la décoration de bâtiments d'énergie ultra-bas passifs?
Septième, afin d'assurer l'effet d'économie d'énergie du bâtiment, il est strictement interdit d'endommager la couche hermétique du bâtiment, et il est strictement interdit de percer des trous en position de la couche hermétique pendant la décoration.
Comment connaître l'emplacement de la couche hermétique dans la maison pendant l'utilisation?
When delivering passive ultra-low energy buildings, a floor plan indicating the location of the airtight layer will be attached. The location of the airtight layer is generally on the inner side of the building envelope structure. If it is a residential system with separate households, the partition walls between households, the partition walls between households and stairwells, and the floor slabs will also be the locations of the airtight layer.
Comment les fenêtres extérieures passives sont-elles connectées au mur lors de l'installation?
Lors de l'installation de fenêtres externes, afin de réduire les effets de pontage thermique et d'assurer l'étanchéité de l'air, la couche d'isolation du mur est généralement appuyée sur plus de la moitié de la largeur du cadre de fenêtre, et les lacunes entre la fenêtre et le mur sont traitées avec étanchéité, avec un matériau de film de barrière à gaz collé à la connexion.
Pourquoi le film de barrière de vapeur étanche est-il attaché au côté intérieur et le film perméable de vapeur étanche attaché au côté extérieur à la connexion à 15 fenêtres?
Waterproof and vapor barrier film can prevent indoor water vapor from penetrating into the gaps between external windows and walls, causing condensation and mold growth when water vapor encounters cold air at the gaps. Waterproof and breathable film can prevent outdoor rainwater from seeping into the room, prevent external windows from leaking water, and at the same time, allow water vapor to penetrate outside, avoiding water vapor from staying inside and causing condensation and mold when exposed to cold.
Quel est le but de l'installation de seuils de fenêtre à l'extérieur de l'ouverture inférieure des fenêtres passives de construction d'énergie ultra-bas passive?
Pour assurer l'étanchéité de l'air, il y aura une couche hermétique à l'intérieur de la structure de l'enveloppe du bâtiment.
Les murs extérieurs des bâtiments d'énergie ultra-bas passifs sont-ils plus épais que ceux des bâtiments ordinaires?
Due to the high requirements for external wall insulation performance of passive ultra-low energy buildings, they are generally thicker; But with the advancement of technology, the replacement of building insulation materials, and the differences in building systems, achieving the same performance will gradually reduce the thickness of the insulation layer.
Quelles sont les exigences pour les portes externes et les fenêtres pour réaliser l'effet des bâtiments d'énergie ultra-bas passifs?
The exterior doors and windows of a building are also the weak link in the insulation performance of the building's external enclosure structure. According to statistics, windows account for about 50% of the heat lost by buildings. Therefore, external doors and windows are required to have good thermal insulation performance, and external window glass should also have good light transmission performance, suitable sun heat gain and shading performance, good air tightness and water tightness performance. For high-rise buildings, depending on the different materials used for external wall insulation, some also require good fire resistance performance.
How do the exterior windows of passive ultra-low energy buildings meet performance requirements?
One is to improve the performance of glass, such as increasing the two-layer glass of ordinary windows to three-layer glass, filling inert gas between glass layers, using warm edge spacers, and using silver plated low-e technology for glass; The second is to improve the performance of the frame material, such as using high-quality multi cavity aluminum-plastic materials, wood or wood aluminum composite materials, broken bridge aluminum profiles, fiberglass polyurethane profiles, etc; The third is to handle the gap between the glass and the frame material well, reduce linear thermal bridges, etc.
Can cat eyes be installed on the doors of 20 passive ultra-low energy residential buildings?
According to current technological processes, installing peepholes on passive doors can affect their air tightness, so they are generally not necessary.
On March 1, 2022, the Ministry of Housing and Urban Rural Development issued the "14th Five Year Plan for Building Energy Efficiency and Green Building Development". The specific goals of the plan are to complete the energy-saving renovation of existing buildings with an area of over 350 million square meters and construct ultra-low energy consumption and nearly zero energy consumption buildings with an area of over 50 million square meters by 2025. During the 14th Five Year Plan period, developing the passive ultra-low energy consumption building industry is an important measure to achieve carbon neutrality in buildings.
