[Sample Distribution] Easy installation with sound insulation performance equivalent to LL-45 and insulation performance comparable to high-performance glass wool insulation material 48K! 40mm thick low-floor substrate material.

Product Name: Chardan SPF400 【Features】 ✔ Low height of 40mm! ✔ Integrated soundproofing and insulation unit ✔ Reduced construction time to less than 1/3 compared to dry double flooring! (In-house research) ✔ Achieved LL-45 with SPC flooring! A multi-type that does not limit the choice of top materials This is a floor soundproofing material laid under flooring with a thickness of 40mm. It has been certified for performance with SPC flooring, which is said to be thin and hard, making it difficult to ensure soundproofing performance. With Chardan SPF400, SPC flooring can be used not only in commercial facilities but also in multi-family housing and welfare facilities where soundproofing and insulation functionality is required. Since it is a form that fills the underfloor space with special sound-absorbing material, it provides both soundproofing performance and insulation effect in one package. SPF400 Thermal Conductivity: 0.040 [W/(m·K)] SPF400HS Thermal Conductivity: 0.033 [W/(m·K)] * SPF400HS is a high insulation version of SPF400. Its composition and basic performance (thickness/soundproofing/constructability/safety) are equivalent to SPF400. Using dedicated edge treatment materials and fastening components, we achieve innovative construction that reduces construction time and noise.

【Sample available!】Simply stick it to the underside of a metal roof to reduce rain noise. With about 30% coverage relative to the roof width, the effect is outstanding!

Product Name: Zetoro NV-αII 【Features】 ✓ Just apply 30% of the width of the roofing material! ✓ Reduces indoor and outdoor rain noise by 10dB ✓ Industry’s thinnest! Despite being only 0.55mm thick, it effectively addresses rain noise ✓ Can be applied without hardening even in winter conditions ✓ Easily cut with scissors or a cutter Metal roofs are excellent in durability, design, and workability, but their soundproofing performance is insufficient, so vibration-damping tape is used to solve rain noise issues. The vibration-damping tape applied to the metal roof converts the vibrational energy from falling raindrops into thermal energy, thereby suppressing the generation of rain noise. The roofs of residences with applied vibration-damping tape reduce noise not only indoors but also outdoors. Zetoro NV-αII, which reduces rain noise by applying just 30% of the roofing material's width, can be used in cover methods during new construction or renovation.

[Speaker] Kentarou Kobe, Senior Consultant Mitsubishi Research Institute, Inc. Power and Energy Division Demand Side Innovation Group [Key Lecture Content] As we strive for carbon neutrality, the importance of stationary storage batteries that support the expansion of renewable energy adoption and the stabilization of electricity supply and demand is increasing. On the other hand, the environment surrounding the battery storage business is undergoing significant changes, including the review of electricity markets and systems, increased renewable energy output control, expanded utilization of demand-side resources, grid connection, cell procurement, cybersecurity, and regional coexistence. In this lecture, we will organize the values required for future battery storage businesses from four perspectives: power system value, renewable energy value, consumer value, and regional value. Based on this, we will introduce points for consideration in business development, focusing on grid-connected and renewable energy co-located systems, taking into account the characteristics of each type. [Lecture Items] 1. Current status of the domestic battery storage market and the future image of battery storage required 2. Market and system trends surrounding grid-connected battery storage and key points 3. Market and system trends surrounding renewable energy co-located battery storage and key points 4. Points for consideration in battery storage businesses that provide multiple values 5. Summary 6. Q&A / Business card exchange

[Lecturers] Accenture Ltd. Industry & Enterprise Headquarters Managing Director Yuya Horiguchi, Head of Telecommunications and Media Practice Japan Senior Manager Mamoru Yonemura, Digital Core Strategy [Key Lecture Content] This presentation will analyze the next structure of the telecommunications industry from the perspective of investment and business strategy regarding 6G. As standardization intensifies in preparation for commercialization around 2030, there is also strong caution that we may "repeat the same mistakes as with 5G." Starting from environmental changes that could not be anticipated in 2020, such as the expansion of generative AI demand, commercialization of NTN (satellite communications), data sovereignty, and power/supply constraints, we will organize the points of discussion on infrastructure investment, business restructuring, sharing, and monetization. From the standpoint of connecting enterprise demand with telecommunications infrastructure, we will present the investment decisions that telecommunications operators should make and the materials for their next steps.
