The higher the rating, the lower the energy (utility) costs. This property is a "ZEH" (zero energy house) with annual utility costs of approximately ¥113,000, achieving a zero-to-zero balance. / Energy-efficient home equipped with solar panels significantly reduces utility bills and allows you to sell any excess electricity! Additionally, direct sunlight on the roof blocks heat, maintaining a comfortable interior temperature. / Free battery installation available during our big clearance sale: In addition to using solar power generated during the day for self-consumption, you can also charge excess power and use it at night or in the event of a disaster. During this campaign, you can install a battery worth a total of ¥2.5 million! The battery provides peace of mind by providing nighttime power and emergency power. / Eco One is a hot water system that efficiently generates hot water using gas and electricity. Its high energy efficiency significantly reduces annual running costs for hot water and heating compared to conventional gas water heaters. Eco-friendly energy savings are also easy on the household budget. / We've installed a high-efficiency, total heat exchange ventilation system (24-hour ventilation) for our condominiums. Planned ventilation circulates clean air year-round, providing a comfortable and healthy lifestyle. / High airtightness and insulation provide whole-house heating and cooling. Stay cool in the summer and warm in the winter, while significantly reducing your annual energy bills. Compare these figures with other companies: ■ UA value (insulation performance): 0.46 ■ C value (airtightness performance): 0.3 / Regardless of the strength of the ground, Seis performs ground improvement work on all of our buildings, striving to build homes on strong foundations. We also offer a 20-year ground warranty, providing peace of mind in the event of an emergency. / Damage to homes is often caused by aftershocks, but the SW Method (Vibration Control Super Wall) has vibration control properties that are extremely resistant to repeated earthquakes, allowing you to live in peace of mind. / Vibration control tape is stretched between the columns, beams and SW panels to absorb energy during earthquakes and reduce shaking. In addition to the earthquake resistance provided by the SW panels, reinforcing with vibration control tape acts as a vibration damper for the entire house. / By applying FFC processing to wallpaper, adhesives, etc., chemicals that cause sick building syndrome are reduced.
