"How to achieve low cost and high quality is one of the core challenges of being a curtain wall consultant."

Times E-PARK

Plug-in composite boutique urban complex

The total construction area of Times E-PARK is approximately 210,000 square meters, of which the second phase has a total construction area of approximately 100,000 square meters, including three commercial office buildings totaling 70,000 square meters, 27,000 square meters of boutique community commerce, and a 4,000 square meter outdoor garden for social gathering.

 

The architectural design concept is: based on the first phase of the office park, expand the plug-in type composite boutique urban complex, striving to use a rich architectural vocabulary to vividly demonstrate the contemporary Guangzhou city that integrates modernity and tradition, city and village, humanities and nature. image and renewed community status.

 

The design is based on the cultural context, based on the spatial function of the composite form, using the rhythmic and rich facade as the modeling technique, and featuring the "wedge-type" community commercial cultural form, successfully creating a "plug-in" for the city.

 

It is also like a filter of contemporary trends, an architectural montage that combines virtuality and reality, reflecting the rapid integration and transformation of urban and rural areas in Guangzhou in recent years, and the urban development process in which diversity and vitality coexist.

High-quality facades add architectural value

Building physical performance analysis + fifth facade design

 

Building physical performance analysis

In response to the sustainable design needs of the project, we teamed up with a number of international green building consultants to collaborate on the project to formulate quantitative design indicators for physical performance targets, which were used to improve the quality of the project and the performance of each curtain wall system.

Analysis conclusions:

1. By using glass with high visible light transmittance, the annual solar radiation heat energy obtained through the windows can be increased by 2-3 times compared with the existing building plan.

2. The use of glass solutions with high visible light transmittance is the main solution to reduce annual lighting load.

3. The model solution of adding an adiabatic heat recovery system is a solution that mainly reduces the annual cooling load.

Fifth facade photovoltaic panel design

Through the design and use of the fifth facade roof, the building can be improved including: energy conversion, energy saving and emission reduction, reducing indoor temperature, improving the aesthetics of the building and increasing the value of the building.

 

Its role is mainly reflected in the following aspects:

1. Energy conversion and supply: Photovoltaic panels can utilize solar energy and convert light energy into electrical energy through the photoelectric effect. This electricity can be used directly by buildings, reducing reliance on the traditional grid and thus lowering energy costs.

2.Energy saving and emission reduction: The use of photovoltaic panels can reduce dependence on fossil fuels, thereby reducing greenhouse gas emissions, such as carbon dioxide, and helping to alleviate the problem of global climate warming.

3.Reduce indoor temperature: Photovoltaic panels installed on the roof can effectively reflect and absorb solar radiation, thereby lowering the indoor temperature, reducing the use of refrigeration equipment such as air conditioners, and further saving energy.

4.Improve the aesthetics of the building: Photovoltaic panels can be used as part of the building and combined with the architectural design to improve the aesthetics of the building.

5.Increase building value: Installing photovoltaic panels can improve the energy efficiency of a building and increase its market value. At the same time, for some areas encouraged by policies, the installation of photovoltaic panels can also enjoy government subsidies or tax benefits.
