Abstract
In this study, totally 370 design data of newly built timber houses in Shikoku, which has been obtained from FY2013 to FY2015, is analysed on estimating energy consumption, energy reduction rate and employing rate of elemental technologies using LEHVES design process such as heat control technology of building envelopes and energy-efficient equipment technology. 265 design data has been obtained in Zone 6, which is called mild climate region, of the Energy Saving standard and 105 data has been obtained in Zone 7, which is called hot humid climate region. Moreover, 50 existing houses’ data, built in mild climate region, is evaluated to compare the differences with newly built houses.
