Shanghai ▎ The full text of the "Ultra-Low Energy Consumption Building Design Standards (Public/Residential)" is here, effective from October 1, 2025!

To thoroughly implement the "Shanghai Urban and Rural Construction Carbon Peak Implementation Plan" and promote the high-quality development of ultra-low energy consumption buildings in the city, the Shanghai Engineering Construction Standards "Ultra-Low Energy Consumption Building Design Standard (Public Buildings)" (DG/TJ08-2466-2025) and "Ultra-Low Energy Consumption Building Design Standard (Residential Buildings)" (DG/TJ08-2467-2025) have been approved and issued by the Shanghai Municipal Housing and Urban-Rural Construction Management Committee, and will be implemented from October 1, 2025.

 

The formulation of these standards is based on the city's regional and climatic characteristics, summarizing practical experience from ultra-low energy consumption building projects in Shanghai, resulting in technical standard texts with Shanghai regional characteristics, reasonable technical indicators, and appropriate technical measures.

Key Technical Points of the Standards

 

1 1. Establish a reasonable energy consumption indicator system. In response to changes in the national building energy-saving standard system, public buildings adopt energy consumption indicators of "15% building energy saving rate + 40% comprehensive energy saving rate"; residential buildings are subdivided into residential and dormitory buildings, with separate energy consumption indicators formulated.

2 2. Guide climate-responsive design measures. In response to regional climatic characteristics, the concept of prioritizing passive design is emphasized. Window-to-wall ratio limits are set: no more than 0.6 for residential buildings and no more than 0.7 for public buildings; natural lighting and natural ventilation are incorporated into the mandatory indicator system for ultra-low energy consumption buildings.

3 3. Formulate appropriate thermal performance indicators for the building envelope. Based on differences in building load characteristics, differentiated thermal performance requirements for the building envelope are established; the main cross-sectional heat transfer coefficient of exterior walls is introduced to simplify the determination of core indicators; residential buildings further enhance the technical requirements for the application of high-performance exterior windows.

4 4. Optimize building airtightness requirements. Residential buildings continue to use the design system of "overall airtightness indicator (N50 ≤ 1.0) + airtightness special design"; public buildings replace the overall airtightness indicator requirement with airtightness measure requirements to accommodate the future expansion of ultra-low energy consumption public buildings to various functional buildings.

 

5 5. Promote low-carbon transformation of heating heat sources. Residential buildings explicitly state that the main heat source of the heating system should not produce direct carbon emissions, effectively promoting the low-carbon transformation process of heating heat sources in residential buildings in the city.

 

6 6. Advocate intermittent energy use mode. To cultivate citizens' habits of intermittent energy use, emphasis is placed on selecting air conditioning systems suitable for intermittent operation, and design requirements such as energy consumption indicators, underfloor heating pipe construction, and temperature control methods that guide intermittent energy use modes are formulated.

 

7 7. Improve energy consumption calculation methods. Provisions are made for the selection of timetables for intermittent and continuous modes of air conditioning systems; calculation parameters distinguish between mid-mounted adjustable shading and external adjustable shading; parameters for window-to-wall ratio of baseline public buildings are adjusted; monthly chilled water temperature parameters are introduced to improve domestic hot water energy consumption calculation methods; elevator energy efficiency grade characteristic parameters are introduced to improve elevator energy efficiency calculation methods.
