About 60% of Custom Home Buyers Prioritize Thermal Environment; Installing Heating in Dressing Rooms/Bathrooms is the Top Heat Shock Countermeasure

Regarding interest in "whole-house air conditioning and indoor environments" in custom homes, the appeal of custom homes lies not only in layout and design but also in the ability to focus on the "indoor thermal environment," such as protection against summer heat and winter cold. However, to what extent do people actually prioritize this, and what are their impressions of whole-house air conditioning systems that maintain a constant temperature throughout the house? We surveyed 140 men and women nationwide who have built custom homes to find out.

60.0% responded that they "prioritized the indoor thermal environment." When asked about the degree of importance, 20.7% said they "prioritized it very much" and 39.3% said they "somewhat prioritized it." Conversely, 36.4% said they did not prioritize it much, and 3.6% said they did not prioritize it at all.

Regarding awareness, 55.7% said they know about "whole-house air conditioning," while 44.3% do not. This suggests that even among those who have built custom homes, awareness is not necessarily high.

When asked about their image of whole-house air conditioning, 70.5% cited "high utility costs" as their primary concern. Other responses included "seems comfortable" (62.8%) and "high installation costs" (61.5%).

Regarding temperature differences between rooms (heat shock), 32.9% said they have felt anxious or considered countermeasures, while 67.1% have not. Among those who considered countermeasures, 41.3% chose to "install heating in the dressing room or bathroom," making it the most common approach.
