jailcd2015082: Study on the Effects of the Difference in Lifestyle Patterns on the Under-Floor Spaces of Foundation-Insulated Houses that Have Air Vents in the Floor

Abstract

In foundation-insulated houses, air vents are sometimes embedded in the floor rather than in the foundation. In this research, we used a simulation to verify the effects of the difference in lifestyle patterns on the under-floor spaces of foundation-insulated houses that have air vents in the floor. Three lifestyle patterns were assumed: (1) Windows kept open day and night (apart from when the house was empty), (2) Air conditioning only used in the daytime (from 10.00 to 13.00), the rest of the time the windows are left open, (3) Air conditioning used in the daytime and evening (from 6.00 to 13.00 and from 15.00 to 22.00), and windows kept closed all day.When residents do not use air conditioning and leave the windows open, the absolute temperature in the living space is high, and as a result the under-floor space also has high humidity.
