Hotron Inc. has launched its new product, the "Vehicle Count Sensor CCS3"! This product is a ceiling-mounted sensor that combines infrared and radar technology. It reliably detects vehicles in both directions with a single unit, accommodating traffic during congestion and vehicle passing, thus achieving efficient occupancy management in large parking lots. Additionally, it can be utilized for exit warning purposes in addition to vehicle counting, contributing to the safe and smooth operation of parking facilities. 'Features' - Improved detection performance against changes in road surface during rainy weather by using both infrared and radar. - Equipped with IP67 waterproof and dustproof performance, making it effective even in salt damage areas. - Various settings can be configured from a dedicated app (for Android devices), with current settings easily understandable at a glance. - The base dimensions are the same as the previous model "CCS2," allowing for smooth replacement of existing equipment. *For more details, please refer to the product information, catalog download, or contact us.*

The increase in inquiries about Hyper CLT sheets is significantly related to its status as a NETIS registered technology. Hyper CLT sheets are civil engineering sheets that utilize wood CLT and are registered under the Ministry of Land, Infrastructure, Transport and Tourism's NETIS as "TH-250021-A." In particular, construction companies engaged in public works are increasingly consulting about "looking for new NETIS technologies," "wanting to utilize creativity and innovation," and "wanting to incorporate materials that contribute to environmental considerations." The attention it receives is also due to its lightweight nature, ease of installation and removal, as well as features unique to wood, such as summer heat reflection measures, suppression of metallic sounds, and CO2 fixation. By adding the new option of NETIS registered CLT sheets to access roads, material yards, and temporary roads that have previously used steel sheets, more companies are considering its introduction in actual civil engineering sites, starting from the awareness that "I learned about it because it is registered in NETIS."

In civil engineering sites, there is an increasing demand to address various challenges such as labor shortages, heat countermeasures, and environmental considerations. Therefore, it is important to have the option of "new technologies" in addition to traditional methods. Hyper CLT mats are a new type of civil engineering mat that utilizes wood CLT. They are lightweight, easy to install and remove, and have excellent transport efficiency. Furthermore, they can provide unique advantages of wood, such as reducing summer glare and metal noise, as well as CO2 fixation. A significant point is that it is a **Ministry of Land, Infrastructure, Transport and Tourism NETIS registered technology "TH-250021-A."** In public works, it can be utilized as a new technology registered with NETIS for proposals involving creativity and environmental considerations. By incorporating new technologies, the scope of site development expands beyond just traditional steel plates. The Hyper CLT mats, which combine wood, NETIS, civil engineering, and CLT, are an option that creates new value for future sites.

SPACECOOL Co., Ltd. and Hitachi, Ltd. will begin a demonstration of the application of radiative cooling technology, which does not require energy for cooling, to stably operate social infrastructure facilities such as power equipment and data centers in response to rising temperatures due to climate change. Both companies are working to establish new thermal measures that balance the stable operation of critical infrastructure with energy conservation. Additionally, Hitachi will utilize the insights gained from this demonstration in the research and development of the "Energy NEXUS," which integrates power, heat, CO2, and data, and will contribute to the creation of solutions for social infrastructure through Lumada 3.0. SPACECOOL and Hitachi aim to expand the application of radiative cooling technology to a wide range of social infrastructure fields, including power equipment, data center-related facilities, and renewable energy-related facilities, by utilizing the data and insights gained from this demonstration. SPACECOOL intends to widely promote this technology as a new option for thermal measures in social infrastructure, contributing to the stable operation of facilities, energy conservation, and adaptation to climate change. *The company names and product names mentioned are trademarks or registered trademarks of their respective companies.*
