What Factors Should Be Considered When Building Glass Greenhouse Structures?

Before embarking on this project with glass greenhouses, we should first consider our regional location, local environmental and climatic characteristics, and the use of glass greenhouses. This is what we need to communicate with the greenhouse designer and builder. For instance, in the northern regions, I aim to create planting and seedling greenhouses, so factors such as maximizing thermal insulation, such as adding an internal thermal insulation system and using double-glazed thick glass as much as possible around the greenhouse, come into play. This takes into account the northern summer's characteristics of intense color and light, and water scarcity. If possible, designing a rainwater collection system and an external shading system in the northwestern region would be beneficial. Additionally, the distinction between planting greenhouses and eco-restaurants or leisure and sightseeing agricultural areas lies in the height design of the internal space. Planting greenhouses can be designed from 4 to 4.5 meters in height, while leisure and sightseeing greenhouses typically have shoulder heights around 5 to 6 meters.
Key Considerations When Constructing Greenhouses

Firstly, the transparency is excellent.

Firstly, it's important to understand that greenhouses are lighted structures, thus requiring excellent light transmission conditions. The light transmission rate is a fundamental indicator for evaluating a greenhouse's light transmission performance. The light transmission rate refers to the percentage of light entering the greenhouse compared to the outdoor light. This rate is influenced by both the light transmission rate of the greenhouse covering material and the shading rate of the greenhouse structure. Moreover, as the angle of solar radiation varies with different seasons, the greenhouse's light transmission rate fluctuates accordingly. Therefore, the light transmission rate becomes a direct factor affecting crop growth and the selection of plant species.

Secondly, consider the greenhouse's insulation properties.

Furthermore, greenhouses should pay attention to their thermal insulation properties. Enhancing the thermal insulation of greenhouses is a direct approach to improving production efficiency and reducing energy consumption. The thermal insulation ratio is a critical indicator of greenhouse insulation performance. The thermal insulation ratio refers to the area of transparent materials with low thermal resistance covering the greenhouse and the area of the maintenance structure with high thermal resistance. The higher the thermal insulation ratio, the better the greenhouse's thermal insulation.

Thirdly, our greenhouses must be durable.

Durability must be considered after the construction of greenhouses, particularly the longevity and aging resistance of greenhouse materials. The durability of translucent materials, influenced by factors such as the load-bearing capacity of the greenhouse's main structure, not only shows a continuous decline in light transmission rate over time, but the degree of this decline is a determining factor in the lifespan of the translucent materials. Due to the long-term exposure to high temperatures and humidity, surface corrosion resistance is one of the key factors affecting the lifespan of greenhouses.
