Proposed Criteria and Scorecard
The rating system’ criteria are developed separately for both the New and Existing facilities, this is mainly due to the difference in the condition of each type of facility, for example the applicability of the HBRC design and construction guidelines as part of the new facilities permit process which was not applied to most of the existing facilities. For the proposed system application, the facilities will be categorized at the time of intent to follow the rating system criteria, where New facilities will be considered as projects that are still under planning with the ability to take into consideration the criteria in the design phase, and the same treatment will also be applied to extensions to already existing facilities, while Existing facilities are those already constructed whether operation is already proceeding or still in the commissioning stage of operation. The differences in the expected intervention level during the transition towards sustainability deemed it necessary that some of the criteria are not equally weighted to account for the different implantation hardships between upgrading an existing situation and implementing a measure from the design phase. The proposed system is discussed below starting with the two general prerequisites, followed by the three criteria categories: Energy, Water and Habitat.
