Abstract
The purpose of this study is to analyze problems and suggest improvements via a status analysis of evaluation criteria and a method for three years after revisions to the standard of the Housing Performance Grading Indication System. The grade distribution works of four accreditation authorities were searched for grading distribution by performance item for 144 cases acknowledged for a 'new standard' (revised standard). It was revealed that 'unequal distribution', in which only certain grading was focused on, and 'no-grading', in which specific grading was not shown occurred on 17 items amongst the entire 27 performance items. The items shown only in 'unequal distribution' were generated for crime prevention content and horizontal evacuation distance. Only 'no grading' items were generated in seven items, which were heavy-weight floor impact sound insulation, remodeling & maintenance(common space), daylight, home networks, fire detection & warning facilities, smoke release & evacuation facilities, and so on. Items in which both 'unequal distribution' and 'no grading' were generated include noise emission in bathrooms, outside noise in sound insulation-related grading, remodeling & maintenance(private space), durability, and application of low emission product, ventilation performance for household units, consideration for the socially underprivileged, such as the elderly, etc. (private space), fire resistance performance. A commonly used method was applied to the evaluation criteria of each performance item in which 'unequal distribution' occurred for construction, and this is grading can be acknowledged without much difficulty. This shows that the housing performance grading acknowledgement criteria is lacking in discrimination from others. Evaluation criteria not showing **** amongst the evaluation criteria of each performance item shows that it is a criteria that is quite difficult to acknowledge for performance grading, and items not occurring * shows that a construction method was applied, which is basically applied to current apartment housing, and thus has no discrimination from others.
