CLT의 코어층 적용 재료에 따른 실내공기질 및 건물에너지 평가

Abstract

This study conducted an evaluation of indoor air quality and building energy efficiency in CLT (Cross-Laminated Timber) construction based on the core layer materials used. The results revealed that indoor air quality measurements were lower than the recommended standards for multi-purpose facilities, maintenance criteria, and new residential buildings. Additionally, using DesignBuilder software, thermal performance and building energy consumption were assessed, with PB (Particleboard) demonstrating the lowest energy usage among LW (Larch Wood), PB (Particle Board), and PW (Plywood). Utilizing the building as a dormitory with a PB structure in Central Region 1 would result in the most efficient energy usage, with a consumption rate of 96.9 kWh/m2 . Furthermore, a building energy assessment was conducted for PB with insulation applied, resulting in energy savings ranging from 9.75 to 17.5 kWh/m2 . The dormitory building in Central Region 1 exhibited the most fficient energy utilization at 84.36 kWh/m2 .
