In Tokyo, under the "Ordinance on the Conservation and Restoration of Nature in Tokyo" enacted in 2001, when constructing new buildings or making additions or renovations on sites of 1,000 square meters or more, it is mandatory to implement greening that meets certain standards on the site and buildings. Businesses must submit a greening plan in advance. Additionally, the amendment to the "Urban Green Space Conservation Act" in 2004 included provisions requiring a certain percentage of greening for large-scale building developments in areas designated by municipalities.

In Tokyo and various municipalities, subsidies are provided for private buildings that undertake greening projects on rooftops and walls to create a lush living environment that considers people and the environment, aimed at preventing global warming, mitigating the heat island phenomenon, and purifying the air. The eligibility, details, and conditions for the subsidies vary significantly by municipality, so please check in advance. *For more detailed information, you can view it through the related links.

Under the Factory Location Law, it is mandatory to establish "green spaces" on the site area of "designated factories," but the required ratio varies depending on the zoning for factory establishment and the prefecture. This article introduces green facilities on building rooftops and similar areas. If your company is lacking in green space as per the Factory Location Law or if you wish to make effective use of your site through rooftop greening, please feel free to consult with us.

By greening the rooftop space, the thermal load from the roof is significantly reduced, achieving energy savings in air conditioning operation. This article introduces the insulation effect of green soil, the suppression of indoor temperature rise, energy-saving effects, as well as measures against the heat island effect and energy conservation benefits, so please take a look.

The concrete surface on the roof receives intense sunlight during the summer, causing its surface temperature to rise rapidly, reaching around 60°C. This heat then flows into the interior through the concrete layer. Furthermore, even when it starts to cool down outside in the evening, the heat does not escape outside but remains trapped indoors. In this article, we will introduce the effects of greening and its energy-saving benefits, so please take a look.

In addition to the differences in wind types due to climate and local conditions, the way wind pressure is applied changes depending on the height of buildings and plants. Therefore, wind resistance measures must be carefully developed considering each environment. Even for rooftop greening, wind resistance measures differ between garden-type and thin-layer type. In this article, we discuss the wind pressure resistance performance of the Super Green MGE method and provide calculations of wind pressure on roof surfaces, so please take a look.

On rooftops that are already completed, there are those finished with a concrete topping and those finished with exposed waterproofing layers that are generally not suitable for walking. Depending on the type of waterproofing layer, it may not be possible to implement rooftop greening as is. Therefore, it is necessary to assess what type of waterproofing layer has been applied by examining the rooftop (balcony). In this article, we introduce the types of waterproofing layers and their expected service life, so please take a look. [Overview] ■ Types of waterproofing layers ■ Expected service life of waterproofing layers *For detailed content of the article, please refer to the related links.
