Experience the Comfort of a Warm Home in Winter

Rigard Corporation, based in Kokubunji, Tokyo, invites you to a unique experiential event titled "A Home Where You Can Feel Comfortable in Short Sleeves, Shorts, and Barefoot". This gathering will take place over two days on December 27th and 28th, 2025, at the Shakujii-Oizumi model house in Nerima, Tokyo. It focuses on showcasing high-performance homes designed to maintain comfort even in winter.

Key Features of the Event

1. Unprecedented Experience: Step into a winter model home and switch into short sleeves and shorts to experience exceptional warmth.
2. Heat Shock Prevention: Enjoy a home where temperature differences are negligible, with outstanding performance ratings of UA value below 0.46 and C value below 0.4.
3. Cost-efficient Heating: Staying warm efficiently, the energy-saving design ensures room temperatures remain between 20 to 23°C even when the outdoor temperature dips below 10°C with just one underfloor air conditioner.

Background: The Hidden Chill of Homes

Heat shock, caused by indoor temperature differences, is a severe health risk, claiming over 17,000 lives each year. Cold areas such as bathrooms and corridors can trigger drastic blood pressure changes, exacerbating health issues. With rising energy costs, ensuring a warm home environment has gained importance for both health and financial well-being.

In recent years, many housing companies have touted their "high insulation" and "high airtightness" features, making it challenging for prospective homeowners to understand the actual warmth and savings on utility bills. Unfortunately, many residents end up regretting their decision, stating that their homes were colder than expected, or heated only in select rooms.

To address these issues, Rigard believes that experiencing the real comfort of a home is crucial for peace of mind. This event aims not only to showcase the significance of home performance but also to reduce health hazards and promote a comfortable and economical living environment.

Event Details: Experience Real Warmth in Winter Attire

Participants at the event are encouraged to wear shorts, short sleeves, and walk barefoot (optional). The goal is not to crank up the heating but instead to highlight the combination of high airtightness, high insulation, and efficient air conditioning that maintains room temperatures consistently across the home, minimizing energy use.

Temperature Uniformity Experience

Walk through the corridors and areas typically regarded as cold, like bathrooms, to witness firsthand the absence of temperature variances that usually lead to heat shock risks.

Heating System Overview

Utilizing an underfloor air conditioning system, Rigard’s design ensures the entire house can be warmed effectively using minimal energy. Even on days with temperatures below 10°C, setting the unit to 23°C keeps indoor temperatures stable around 20 to 23°C, providing a warm floor that is pleasant to walk on barefoot.

Technical Verification: Understanding Warmth through Data

Rigard's homes are meticulously designed for warmth during winter, focusing on insulation, airtightness, and ventilation systems. The model house achieves:

• - C value (Airtightness): 0.098 cm²/m², significantly surpassing the old national energy conservation standard of 5.0 cm²/m².
• - UA value (Insulation Performance): 0.42 W/m²K, comparable to the high standards of HEAT20 G2 grade insulation.

Homeowners who've built with Rigard often remark on the comfort, saying they can wear shorts even in winter or only need a light blanket at night.

This experience illustrates that genuine warmth can only be achieved in homes designed with suitable insulation and airtightness. Attendees will have a chance to compare both data and personal experiences of their homes' comfort levels.
