Introduction
Published in Chitrarekha Kabre, Synergistic Design of Sustainable Built Environments, 2020
A rating system approach is represented by the green building certification systems that differ from building standards in that they typically take a ‘whole building’ approach. Sustainable building rating systems are defined as methodologies that examine the performance or expected performance of a ‘whole building’ and translate that examination into an overall assessment that allows for comparison against other buildings (Fowler and Rauch 2006). Sustainable building rating systems are designed to foster and recognize different aspects of sustainable practices during the design, construction, and operation of a building and to incorporate the best practices in reducing the adverse impacts of the building on the environment. There are more than 600 different rating systems in use or being developed worldwide (BRE 2008). Table 1.3 summarizes some of these rating systems according to regions.
Reuse

Greywater reuse and rainwater harvesting have been encouraged and mandated in planning policy and building rating schemes in some jurisdictions. Green building certification systems such as the US-based LEED, the UK-based BREEAM and the New South Wales BASIX schemes all include greywater and rainwater harvesting as contributing towards higher eco-building ratings. However, evaluation of rainwater harvesting systems has shown overestimation of the water savings achieved, indicating that these systems need to be better managed and integrated into building operation, maintenance and water management programmes (Moglia et al., 2016). Integrating user and household needs into the design and operation of decentralised water reuse options is important to achieve the full water supply benefit.

LEED is one of the green building certification systems which provides verification that a project was designed and built according to defined metrics. It systematically assesses the level of environmental quality through checklists, assigning scores and rewarding the project. The assessment is structured by thematic areas (credit categories), which represent buildings’ key aspects. Each credit category contains explicit topics, called prerequisites and credits. While prerequisites are the minimum requirements that every project needs to meet, credits hold certain number of points, awarded to the project when it complies with the credit rules. Based on the final credit score, the project can earn one of four LEED certification levels: certified, silver, gold and platinum (World Green Building Council 2016-2020). The credit score system is based on the following criteria: All credits are worth at least 1 point; prerequisites are mandatory and do not score;All credits have a positive integer value, there are no negative values;There is maximum of 110 points to obtain.
Indoor environmental quality and occupant satisfaction in green-certified buildings

Green-building certification systems – such as Leadership in Energy and Environmental Design (LEED) in the US, the Building Research Establishment Environmental Assessment Method (BREEAM) in the UK, Green Mark in Singapore, and Green Star in Australia – are assuming a prominent role to promote the sustainability agenda in the design and operation of buildings. However, although rating systems certify buildings under several categories (e.g. energy, water efficiency, sustainable sites, materials and resources, etc.), their role towards enhancing occupant satisfaction with indoor environmental quality (IEQ) – i.e. the thermal, acoustic, luminous and air-quality parameters that create the perceived internal ‘ambient environmental conditions’ (Hedge, 2000) – has been debated for a long time, but is still not fully characterized.
