Luudman All Air Conditioning System: Indoor Space with Spring like Seasons

Passive residential buildings, abbreviated as low energy buildings and referred to as "passive houses" abroad, are energy-saving buildings built based on passive design. Passive design "refers to the use of natural principles such as sunlight, wind, temperature, and humidity, with minimal reliance on conventional energy consumption
(Mainly referring to air conditioning and underfloor heating). By using architectural techniques such as planning, design, and environmental configuration to meet cooling and heating needs with minimal energy supplementation, it improves and creates a comfortable living environment, making it a highly energy-efficient and comfortable building.

40% of energy consumption comes from the construction and use of buildings

China adds 2 billion square meters of new buildings every year, accounting for 50% of the world's total. Of the 46 billion square meters of existing buildings in China, 95% are non energy-saving buildings, which not only waste resources but also pollute the environment.
Passive room energy consumption is less than one-third of the current building energy efficiency standards in China, and is listed as an important aspect of energy-saving and low-carbon development in the construction field during the 12th Five Year Plan period.

High airtightness, effectively blocking outdoor pollution, efficient PM2.5 filtration, rejecting haze, warm in winter and cool in summer, all seasons like spring
Farewell to Huangmei Day, winter is not dry, noise isolation, quiet enjoyment, adjustable and controllable temperature, and inhibition of disease and mold growth

Passive Low Energy Residential · Going Home is the Start of Enjoyment. The Value of Passive Low Energy Residential Reflects 2
Energy conservation and environmental protection
Significantly reduce the use of petrochemical energy, reduce carbon emissions, and reduce environmental damage and pressure
The north can cancel heating facilities, while the south can significantly reduce the energy consumption of air conditioning
If the passive low energy building technology of Langlu Technology is used in all Chinese buildings, it can save 900 million tons of energy consumption per year.
It is equivalent to one third of the national coal mining output and the total energy consumption of Germany in two years.
From a global perspective, the construction sector contributes 40% of total carbon emissions and is a key sector in achieving carbon neutrality goals. The carbon emissions during the construction process mainly come from the production, transportation, and construction of building materials. The main sources of carbon emissions during the operation of buildings are heating, air conditioning, lighting, socket equipment, special energy (such as laboratories, data centers, etc.), and transportation energy (charging stations).
Building carbon neutrality can mainly be achieved through three aspects: demand reduction, ultra-high energy efficiency, and energy substitution.
From the perspective of spatial orientation, it all points to the development of low energy buildings.
