Owner approach of sustainability
The Project is the first generation of the Landsea household air-conditioning system. It is a major attempt to adjust from centralized operation to household separation. First of all, from the perspective of energy, the right to use the air conditioner is returned to the user. The user decides whether to consume energy in exchange for comfort according to his or her sense of body. It is a simple and effective behavioral energy saving from equipment/operational energy saving. Secondly, good building performance is still a prerequisite for reducing energy consumption. Although the project has changed the system form, the energy conservation of the building itself is still an important feature of the project. At the end, capillary radiation & replacement fresh air is used to cope with the delay effect when the system starts and stops. However, when the indoor temperature and humidity are stabilized, the indoor temperature and humidity uniformity and the low wind speed environment provide a relatively comfortable experience compared with the convection system. In addition, in terms of renewable energy utilization, solar hot water is designed in Building 1-3 and Building 5, and ground floor heat pump air conditioning heating and domestic hot water are used in Building 17, which reduces energy consumption to some extent.
The project's attempt is an important embodiment of Langshi's differentiated products. The whole system is a complete system from the building itself to the system design. She has better energy-saving performance, more comfortable indoor experience, and considers renewable energy in the same kind of products. Use, is a more comprehensive set of products.
The first consideration of the project is passive energy-saving technology, which makes the building's performance to a good level. It is combined with the household-type HVAC system to become a design system. It can achieve energy-saving operation and reduce energy consumption.
Starting from indoor comfort, the radiation system is operated to create a uniform indoor temperature environment; in addition, the household fresh air system provides 24 hours of clean fresh air to the residents, taking away moisture and pollution, ensuring high quality air quality indoors; The house is freely adjusted according to climatic conditions, personal preferences, etc., and implements an energy-saving operation mode in which the user pays.
Renewable energy has also been utilized in this project. On the one hand, it meets the demand for hot water in some residential houses. On the other hand, it also considers a certain degree of energy conservation, resulting in good economic and social benefits.
Building users opinion
Landsea invited Gallup to conduct a customer satisfaction survey on the project, including system, design of the house and public area, aesthetic appearance, reasonable design of the public area, room lighting effect, sound insulation effect, and room design rationality. According to the survey of the pipeline layout, the scores of 85 points or more were obtained in terms of appearance, room lighting and pipeline layout, and the design of the public area and the type of the room were second.
In the community environment and planning links, the overall layout, greening and landscape, activity facilities, internal road convenience, and floor space are basically 80 or higher.
In the late stage property maintenance, the community clean, green maintenance, public facilities maintenance, vehicle management, etc. are also more than 80 high scores.
Evaluation from customers: The overall size of the apartment is compact and cost-effective. With a south-facing balcony, it is very transparent in the north and south. The kitchen is located at the entrance to the room with a window that reduces fumes from other rooms. The bathroom is located between the two bedrooms, easy to use, dry and wet separation, to avoid the air is too humid, easy to clean and work in the future. Both the main and the second are facing south, which also improves comfort.
