Free online seminar "Is that so? Mandatory efforts that must be made?! Start of the energy-saving performance display system" will be held on July 23, 2024 (Tuesday) from 13:30 to 14:00!

  • Seminar・Event

The residential business will hold a free online seminar titled "Is that so? The obligation to make efforts that must be done? The start of the energy-saving performance labeling system" on July 23. The "Energy-Saving Performance Labeling System" will begin in April 2024. Since the obligation to make efforts only applies to sales and rental businesses, do you think "custom-built homes are not related"? From the perspective of homeowners, it is becoming a time where it is not "I don't have to do it because it's an obligation!" but rather "If I'm buying a house, I want one with an energy-saving performance label!" Now that the times are demanding it, we will review the "amendment to the Energy Conservation Law" and explain the "Energy-Saving Performance Labeling System" in an easy-to-understand manner. ≪Webinar Details≫ Date and Time: July 23, 2024 (Tuesday) 13:30–14:00 Participation Fee: Free (Pre-registration required) Participation Method: Zoom (You can enter the room 15 minutes before the start time) \ Recommended for those with the following questions / 1. What exactly is the energy-saving performance labeling system? 2. What will the obligation to comply with energy-saving standards specifically entail? 3. Is it true that there are two types of energy-saving performance labeling systems? 4. I want to address this internally, but what should I do?
