The country's first constant temperature and humidity "passive house" hotel unveiled in Changsha City

The indoor temperature is stable throughout the year at 22°C-26°C, the humidity is controlled at 40%-60%, the formaldehyde content standard is 0.001, the super filtering PM2.5 makes fresh air surround, the whole house is intelligently customized home, and energy saving is 90% compared with traditional buildings... On November 1st, the first high-tech "Breathe Breathing" hotel in the country built by Hunan Ouyisha Technology Co., Ltd., located in Fan City, Xiyingmen, Changsha, will soon be put into use.

Speaking of "passive house", its concept originated in Germany, but it also has a deep connection with my country. In 1986, Dr. Pfister from Germany was invited to China to study and solve the problem of indoor heating in the southern region in winter. In 1991, the first passive building integrating energy saving, comfort and good indoor air quality was born in Germany.

To heat and cool the residence, air conditioners and floor heating are mainly used nowadays, which will undoubtedly cause a lot of energy consumption. Through the development of indoor "passive houses", the contradiction between better life and energy saving ideas can be easily resolved. Li Xia, vice president of Hunan Building Energy Conservation Association, PHI German Passive House designer, and chairman of Hunan Ouyisha Technology Co., Ltd. Introduced that by using high-tech materials to recover the heat in the indoor exhaust gas, the indoor "passive house" greatly reduces energy demand. Compared with the outer wall of the "passive house", the indoor "passive house" has a better thermal insulation effect.

In addition to constant temperature and humidity, the fresh air heat recovery system of the indoor "passive house" also realizes the flow of fresh air inside and outside, allowing the room to "breathe". Li Xia further added that the construction of an indoor "passive house" needs to meet the strict requirements of thermal insulation, air tightness, fresh air system, and high-standard design, construction and management. Although a certain amount of cost will increase in the initial stage of construction, the entire life cycle cost of the building is much lower than that of traditional buildings.

Now that the earth is warming, it is urgent to save energy. Hunan Ouyisha Technology Co., Ltd., which has been engaged in the insulation industry for 14 years and participated in the compilation of the Hunan Provincial Residential Building Energy-saving Design Standards and Hunan Public Building Energy-saving Design Standards, is committed to promoting the popularization and development of indoor "passive house" technology in China. In order to allow the general public to enjoy a green and comfortable indoor "passive house" living environment, the company creatively invented the patented indoor "passive house" technology. It also cooperates with first-line home appliance manufacturers and brand designers to provide a one-stop solution for the design, decoration and construction of indoor "passive houses", so that people can enjoy the highest-end services and comfortable environment with the least money.
