The Green Infrastructure Flexible Model (GIFMod) is an open-source computer-based modelling tool to evaluate the performance of urban stormwater and agricultural green infrastructure practices that aim to reduce the volume of stormwater runoff entering sewers or receiving streams and to improve water quality. GIFMod allows users to build conceptual models of green infrastructure practices to predict their hydraulic and water quality performance under given weather scenarios. It also allows for interpreting field and lab data via deterministic and probabilistic inverse modelling.

The Green Building Index (GBI) is Malaysia’s recognized green rating system to promote sustainability in the built environment and raise awareness about environmental issues and responsibility to the future generations. The tool provides an opportunity for project developers and owners to improve green design and construction. The GBI assessment for buildings evaluates the environmental design and performance of buildings. The evaluation process consists of a Planning Assessment, a Final Planning Assessment, resulting in a pre-certification, and a Completion & Verification Assessment, resulting in a final certification. To maintain the certification, reassessments are required every three years.

The Global Sustainability Assessment System (GSAS) is a performance-based system developed for rating green buildings and infrastructures. The primary objective of GSAS is to create a sustainable built environment that minimizes ecological impacts and reduces resource use, considering the specific needs and context of the Middle East and North Africa regions (MENA). The purpose of GSAS Design & Build Parks Scheme is to provide recommendations and guidance for the effective implementation of sustainability goals within park projects.

EDGE is a tool to estimate the resource use of buildings already during the planning phase and awards projects that save resources. The cloud-based platform has a sophisticated set of city-based climate and cost data, consumption patterns and algorithms for predicting the most accurate performance results. On this basis, the tool calculates additional costs to build green and how long it takes to earn back the money through operational savings. With EDGE, the IFC aims to deliver a solution to prove the business case for building green and unlock financial investment. Based on the performance, buildings can receive a certification.

The DGNB System for Buildings is a planning and optimization tool for sustainable buildings. The tool evaluates the environmental, economic, sociocultural / functional, technical and process quality of projects. There are different types of certifications available across the life cycle of buildings: (1) DNGB pre-certification for new constructions, (2) DNGB certificate for new constructions, (3) DNGB certificate for buildings in use (plus a recertification option), (4) DNBG certificate for existing buildings, (5) DNGB certificate for renovated buildings and (6) DNGB certificate for dismantling. Assessments are undertaken by independent, DNGB-trained auditors. DNGB undertakes a final conformity check before the certification is awarded.

The Comprehensive Assessment System for Built Environment Efficiency (CASBEE) helps to understand sustainability conditions of cities across environmental, social and economic aspects. It measures the sustainability of buildings across diverse quality criteria against the environmental load defined as CO2 emissions per capita per year. The resulting sustainability qualification supports the development of effective sustainability measures. The CASBEE tool family for building scale offers a broad range of assessments for single buildings, including new constructions (CASBEE-NC), existing buildings (CASBEE-EB), renovation (CASBEE-RN) and temporary construction (CASBEE-TC), among others.

BREEAM Buildings Technical Standard is a sustainability assessment method for the building sector with individual standards for (1) New Constructions, (2) In-Use Buildings and (3) Refurbishments. The tool assesses the environmental, social and economic sustainability performance of buildings, with the aim to enhance buildings’ economic and social value whilst mitigating environmental impacts and enhancing user satisfaction. After the assessment, an independent third-party verification takes place and successful projects receive certification. A pre-approval version for planning processes is available.

BEAM Plus Buildings supports the reduction of environmental impacts of new buildings of any type (residential, commercial and industrial), while at the same time improving environmental quality and user satisfaction. The assessment can also be used when planning for a major refurbishment or alteration, including wholesale or partial conversion. The performance of buildings is rated with a point scoring that can result in a certification. A provisional assessment version and a version for existing building (BEAM Plus Existing Buildings V2.0), including a comprehensive and a selective scheme option for individual adjustments, are available.

The Comprehensive Assessment System for Built Environment Efficiency (CASBEE) for Cities helps to understand sustainability conditions of cities across environmental, social and economic aspects. It measures the sustainability of cities according to quality criteria against the environmental load of the city defined as CO2 emissions per capita per year. The resulting sustainability qualification supports cities in the development of effective sustainability measures. The CASBEE for Urban Development (CASBEE-UD) tool is a standalone version developed for the assessment of partial or whole groups of buildings on a smaller scale than CASBEE for Cities.

The Pearl Community Rating System (PCRS) promotes the development of sustainable communities and improved quality of life in Abu Dhabi. The tool encourages water, energy and waste minimization, local material use and improved supply chains for sustainable and recycled materials and products. The PCRS is applicable to developments that are multiple plot subdivisions, with a vehicular network and community facilities or amenities. The tool requires master plan teams to develop Pearl Rating targets and guidelines for all buildings within the community. Since May 2010 all new community developments in Abu Dhabi must at least achieve a “One Pearl” rating.
