First, a high-performance green building in the second decade of the 21st century consists of construction materials and processes and continuous operational performance. It is important to note that eco-bleaching, which is defined as the use of ecological statements that are not true or cannot be verified, but that are used to sell products or a corporate image, has become commonplace as companies try to remain competitive in the green market. Post-occupancy evaluations began with extensive monitoring of buildings for at least one year; the energy flows established from the measured data were used to calibrate building models for energy simulation performance. Although LCAs are not yet a constant requirement of green building classification systems and codes, there is a tendency to require them and to improve the methods for carrying them out.
Building for Environmental and Economic Sustainability (BEES) Developed by the Building and Fire Research Laboratory of NIST (National Institute of Standards and Technology) with support from the U. In addition, comparing essential issues such as cost, ease of use and building performance will help determine which building classification system is applicable and what level of certification is possible. Energy consumption in buildings can have the greatest environmental impact of any aspect of the building. Greater emphasis is also being placed on achieving the resilience of buildings, something that is beginning to be addressed in green building rating systems.
The various rating systems offer options that can help the designer and the client to adapt the outcome of the project based on a wide range of objectives and approaches to address sustainability issues and other green building requirements. Both new buildings and existing buildings and interiors can be evaluated using Green Globes, whether commercial or multi-family. Green Star SA certification is a formal process that involves a project using a Green Star SA qualification tool to guide the design or construction process, during which a documentation-based presentation must be submitted as proof of achievement. This project produced standard performance metrics and procedures to determine the energy performance of buildings, the performance of the lighting system, the performance of the photovoltaic system, and the energy from the source and the emissions from energy use in buildings.
Rating systems also clearly describe what ecological standards should be followed and what types of green products should be included in construction specifications. The International Green Building Code (iGCC) provides a comprehensive set of requirements aimed at reducing the negative impact of buildings on the natural environment. Third-party labels and organic product certification programs can be useful for evaluating the attributes of organic products, as they validate that the product meets certain independent industry standards. In fiscal year 2021, BEES Online 2.1 will undergo a critical third-party review of both the underlying LCA data and the software calculations to align the BEES validation with the requirements of green building certification programs.
