Reduction of LCCO2 emissions
Compared to conventional construction methods, membrane structural buildings can significantly reduce LCCO2 emissions throughout the construction, operation, and demolition phases, contributing to sustainability. In particular, the reduction of interior lighting due to solar transparency of the tent roof also reduces running costs.
In addition, the lightweight frame makes it easy to make large openings and saves power consumption by eliminating the need for lighting during the daytime.
Heat island control
White membrane roofing is a building material with high solar reflectivity and low heat storage.
As a result of measuring the sensible temperature of each roofing material on a station platform in summer, it was found that, compared to metal and slate roofing materials, the sensible temperature of membrane roofs was 1.5°C lower than that of metal roofs and 3.5°C lower than that of slate roofs. In addition, with a maximum illumination of 16,000 lx, much brighter than metal or slate roofs, membrane roofs provide a brighter, cooler environment.
Membrane roof
Air temperature: 35°C / Attic surface temperature: 40°C
Average radiant temperature {MRT}: 37 °C / sensory temperature {action temperature OT} : 36 °C
Maximum illumination: 16,000lx
Metal roof
Air temperature: 35°C / Attic surface temperature: 40°C
Average radiant temperature {MRT}: 37 °C / sensory temperature {action temperature OT} : 36 °C
Maximum illumination: 16,000lx
Slate roof
Air temperature: 37°C / Attic surface temperature: 55°C
Average radiant temperature {MRT}: 42 °C / sensory temperature {action temperature OT} : 39.5 °C
Maximum illumination: 2,400 lx
Photocatalytic tents
We use photocatalytic tents in our membrane structural buildings, which have a “self-cleaning” function with the power of sunlight and rain, even if it gets dirty.
In addition, it ensures high light transmittance and reduces the rise in room temperature, making the space more comfortable. This results in higher air conditioning efficiency, which contributes to lower running costs, energy savings, and environmental issues. At the same time, it also cuts harmful ultraviolet rays by more than 98%, thereby preventing quality deterioration due to high temperatures and color degradation due to ultraviolet rays. In addition, amid concerns about the environmental impact of nitrogen oxides (NOx), which are contained in exhaust gases and cause air pollution, photocatalytic tents are attracting attention for their ability to remove nitrogen oxides (NOx) and purify the air.
Pollution control membrane Silt Protector
Sludge and silt polluted water spreading in port and other water area construction projects is a major obstacle to environmental preservation. The anti-pollution membrane “Silt Protector” developed to prevent the outflow of such pollution contributes to environmental protection, controls the inflow of harmful substances, and maintains water quality. This protects ecosystems and coastal areas. In addition, Silt Protector can be used in a wide range of installation conditions, from calm waters to rough seas, and have a proven track record.
Flexible container bag
Flexible container bags are lightweight, reusable, and efficiently transported. This reduces energy consumption for transportation and waste. It is an environmentally friendly logistics solution that contributes to the effective use of resources and waste reduction through the use of renewable materials and product protection.
