Reach Fine Chemical Lab Building, Guang Dong, China

The laboratory is located within the Reach Factory Area in JiangMen, Guangdong. The first floor houses the wastewater treatment plant and administrative offices, while the third and fourth floors are chemical testing laboratories. The exterior walls are constructed from blue bricks and wooden louvers, with sliding aluminum windows behind the louvers. As a result, the laboratory benefits from extended periods of natural ventilation throughout the year.

A notable feature of the construction is the use of the double-layer wall method, a traditional technique from the Xin Hui region of Guangdong. This method has been widely used in the region for its excellent thermal insulation properties, especially in harsh climates. The inner layer of the outer wall is made of red brick, which meets the thickness requirements set by Chinese national standards, while the outer layer consists of locally produced blue bricks approximately 5 cm thick. The air layer between the two walls provides effective insulation for the building.

Other materials used in the construction include low-cost washed stone combined with glass curtain walls. The total cost of the project was approximately 2 million RMB, making it a highly cost-effective building.

Upon completion and throughout its operation over the course of the year, the laboratory has proven to be a low-energy-consumption building with minimal reliance on air conditioning. The chemical researchers working in the laboratory also greatly appreciate the natural ventilation environment.

本實驗樓位於廣東江門瑞期廠區內 , 一樓為汙水處理機房與行政辦公室 , 二三四 樓為化工實 驗室。外牆由青磚與木百葉所組成,百葉背後為推拉鋁 窗。因此在 一年四季實驗室有很長的時間採用通風對流。構造特點在於採用廣東新會本土 雙層牆形式的砌法,此工法在氣候嚴峻 的內地流傳已久,它 提供了良好的隔熱 保溫。

雙層本案外牆的內層背牆為中國國家規範所規 定之厚度紅轉牆,外層牆 則為當地所生產厚約 5cm 之青磚。兩層牆之間的空氣層,替本建 築物創造了 良 好的隔熱條件。其他部分的材料則為造價低廉的洗石子搭配玻璃帷幕。 本案總造價約兩百萬人民幣,是經濟的建築。 完工後在一年四季的運轉中 證明了本案是極少使用空調的一棟低能耗實驗樓。而在實驗樓工作的化工研究人員也非常享受在自然通風工作的環境。
