Thermal Performance Evaluation of a Dynamic Insulation Technology Applied to a Timber Framework House in a Real Environment

Abstract

This paper presents the thermal performance evaluation of a dynamic insulation technology applied to the building envelope of a timber framework house. The concept of dynamic insulation technologies is to draw outside air in through insulation materials in a wall to recover conduction heat loss from inside the building. The authors applied dynamic insulation technology to the walls and ceiling of a timber framework house to allow outside air to pass through permeable insulation materials within the walls and ceiling. The experiment was conducted at a building in Sapporo, Hokkaido to evaluate the thermal performance of a building envelope with dynamic insulation technology in a real environment. The results showed that the dynamic insulation technology can significantly reduce heat loss through the building envelope.
