Sweden
The Sweden Green Building Council introduced its own certification system in 2011 with Miljöbyggnad which is based on Swedish standards and legislations. It is currently in its 3rd iteration with Miljöbyggnad 3.1 released in April 2020. Miljöbyggnad has three levels of certification: Bronze, Silver and Gold. It is used to certify both new and existing constructions. It assesses 3 categories, namely:
- Energy consumption
- Indoor environment
- Materials and chemicals.
Among these categories, there are 15 further sub-categories which have its own set of requirements for each certification levels. For example, for the “Energy use” sub-category, Bronze level requires energy use to be less than 65% of the requirements of the BBR, the Swedish Building Code. After 3 years, another follow-up inspection is conducted to see that everything is in the correct order and the standards are still being met.
Besides Miljöbyggnad, the Sweden Green Building Council also administers the Swedish version of the British BREEAM adapted for the Swedish construction practices and standards, called BREEAM-SE. It was first introduced in Sweden in 2013 and is used to certify new constructions.
United Kingdom
The Building Research Establishment Environmental Assessment Method (BREEAM) is recognized as the first Sustainability Assessment Method for buildings. It was launched in 1990 by the UK-based organization Building Research Establishment (BRE).
BREEAM certification is carried out on the basis of a scoring system where projects are assessed on the basis of 10 categories (with individual weightings differing by project type) as follows:
- Management
- Health and well-being
- Hazards
- Energy
- Transport
- Water
- Materials
- Waste
- Land use and ecology
- Pollution
- Surface water run-off
Each category is sub-divided into a range of assessment indicators, each having its own aim, target and benchmarks. When a target or benchmark is reached, the asset is given credits (or points) by a qualified BREEAM assessor. The category score is calculated according to the number of credits attained and the category weightings. Once the development has been fully assessed, the final performance rating is determined by the sum of the weighted category scores. The final performance rating is specified as:
Rating Level | Percentage score |
---|---|
Outstanding | ≥85% |
Excellent | ≥70% |
Very Good | ≥55% |
Good | ≥45% |
Pass | ≥30% |
Unclassified | <30% |
A qualified assessor evaluates a building or project and ensures that it meets the quality and performance standards of the selected scheme. In some countries such as Netherlands, Germany and Sweden, there are national operators that officially certify for BREEAM adapted to that country’s standards, processes and construction methods.
BREEAM certification has also been made mandatory for governmental construction projects in the UK. According to the Common Minimum Standards for governmental construction, an environmental assessment is required on all public projects and further states that, “where BREEAM is used, all new projects are to achieve an ‘excellent’ rating and all refurbishment projects are to achieve at least ‘very good’ rating.”
United State
In 1998, the Global Green Building Council devised its own building certification system through the Global Green Building Council (GGBC) certification. It has its own set of criteria for assessment and utilizes the ASHRAE codes and standards. Due to its simplicity and ease-of-use, the GGBC quickly gained international recognition within a short period. Over the years, GGBC has undergone many changes and is now currently in its fourth iteration, which was launched in late 2013.
- Building Design and Construction: For new construction or major renovations
- Interior Design and Construction: For commercial interior fit-out projects
- Building Operations and Maintenance: For existing buildings undergoing improvement but with little construction work
- Neighborhood Development: For new land development projects or redevelopment projects
- Homes: For single family, low-rise multi-family or mid-rise multi-family homes
- Cities and Communities: For entire cities or sub-sections of a city. Assessment of a city’s water consumption, energy use, waste, transportation etc.
