Abstract

Currently, laws and rating systems related to residential ventilation systems focus on improving indoor air quality and responding to fine dust problems rather than energy saving technologies. In terms of energy savings, the ventilation system of an apartment house has a large ripple effect because a system developed for an apartment house can be applied to several households at the same time. The purpose of this study is to analyze the laws, rules, rating systems, and existing literatures related to residential ventilators, and to derive a system improvement plan for reducing ventilation energy of residential buildings. Through the analysis of domestic policies, laws and rating systems related to residential ventilation systems, the performance standards were analyzed with energy-related provisions of mechanical ventilation systems applied in residential buildings. The basic performance of mechanical ventilation systems of residential buildings should comply with the Rules on facility Standards of Buildings. However, energy savings need not to be considered mandatory. For this reason, firstly through the analysis of existing research, room-by-room control and bypass control were derived as ventilation energy reduction technologies. and filed experiments were conducted to verify the technology. As a result of the field test, when the bypass mode was applied, it was reduced by 42~55% compared to the heat recovery ventilation mode. When room-by-room control is applied, fan power can be reduced by 8 to 49% compared to all-room control. In this study, based on the research results, improvement proposals for ventilation-related laws, rules and rating systems were proposed. It is to reflect the contents of room-by-room control and bypass control in the residential ventilation system.
