Core Viewpoint - The event highlighted the implementation of new energy-saving standards for public buildings in Shandong, aiming for a 78% energy efficiency improvement, alongside the existing 83% standard for residential buildings, reflecting a significant push towards energy conservation and carbon reduction in the construction industry [3][4]. Group 1: Energy Efficiency Standards - Shandong is set to implement a new public building energy-saving standard of 78%, which is the first of its kind in the country, effective from August 1, 2023 [4]. - The residential building energy-saving standard of 83% was already implemented on May 1, 2023, marking a significant advancement in energy efficiency requirements [4]. - The new standards emphasize the use of all-electric designs for energy systems, excluding centralized heating, and aim to enhance the thermal performance of building envelopes [4][5]. Group 2: Green Building Promotion - The promotion of green buildings is a key focus, with requirements for new urban residential buildings to comply with green building standards, and public buildings funded by government or state-owned investments to meet at least two-star green building standards [3][4]. - The application of green building materials is mandated, with specific percentages required for different star ratings of green buildings: 10% for one-star, 20% for two-star, and 30% for three-star buildings [3][4]. Group 3: Market Opportunities and Innovations - The new energy-saving standards are expected to drive the adoption of high-efficiency insulation materials and innovative construction methods, creating new market opportunities for the construction industry [5][7]. - The introduction of advanced materials, such as composite insulation boards, is gaining traction, with benefits including reduced thickness and improved thermal performance, leading to cost reductions for developers and buyers [7][9]. - The event showcased new technologies and products, including integrated photovoltaic materials that serve both decorative and energy-generating purposes, indicating a trend towards multifunctional building materials [9].
