·As one of the technologies for the improvement of urban environments, interest in rooftop tree planting technology is increasing. BCJ evaluates this new technology, which is applied to roofs which may be flat or sloped, and which is also used on balconies. Because rooftop greening is realized by combining various engineering components, it is evaluated as a system, rather than evaluating each engineering component separately. These evaluations are performed based on the approval standard "Technology for Rooftop Greening for Better Environment”.
The Approval for Rooftop Greening evaluates the following three items:
The outline of evaluation of each item is as follows:
Evaluation of basic performance is performed on the following items:
1) Evaluation of individual element technologies and evaluation of combinations of individual element technologies
2) Evaluation of practical feasibility
Evaluation of environmental load is performed in consideration of the whole life cycle, in principle. When the whole life cycle cannot be taken into consideration, after clarifying the range, etc., it is limited to the specific stage of a life cycle, and evaluated accordingly.
To evaluate the environmental improvement effects of rooftop greening technology, buildings that have had this technology applied to them are compared with those that have not.
The above are criteria for evaluating the environmental improvement effect of buildings. There is a high social demand for each of these criteria.
Gain differentiation from other technologies by capitalizing on the BCJ approval mark in advertisements and other media, once approval is received.
