    Building energy efficiency assessment

    Building energy efficiency assessment refers to the activity of evaluating the energy consumption, thermal performance and energy-using system performance of buildings through calculation, verification and necessary testing.

    Building energy efficiency assessment: the activity of evaluating the energy consumption, thermal performance and energy-using system performance of buildings through calculation, verification and necessary testing.

    Building energy efficiency label: according to the results of building energy efficiency assessment, make clear the building energy efficiency level to the society or the property owner.

    The relevant documents
    Notice on the pilot implementation of marking system for energy efficiency assessment of civil buildings (document NO. 80 [2008] of the Ministry of construction)
    Interim measures on the administration of marks for energy efficiency assessment of civil buildings (annex 1 to document NO. 80 [2008] of the Ministry of construction)
    Notice on the inspection and evaluation of the completion of civil building energy saving in Shanghai (trial), Shanghai construction and safety quality supervision [2009] NO.029 document

    The significance of energy efficiency measurement:
    I. Apply for government subsidies
    According to the notification “the support measures of building energy conservation and green building demonstration project in Shanghai”(Shanghai building material group built to [2016] NO. 432) and “the Shanghai building energy-saving demonstration project declare guide ”and supplementary opinions file indicated the qualified projects may apply for government subsidies, after the project completed, should be carried out on its energy efficiency evaluation work, and energy efficiency assessment report issued within the allotted time. The types of demonstration projects include: new high-standard energy-saving buildings, application of renewable energy buildings, energy-saving renovation of existing buildings and other projects.

    II. Requirements for completion acceptance
    In order to implement the Ministry of housing and urban-rural development "interim measures for the administration of marks for the assessment of energy efficiency of civil buildings" construction department [2008] NO. 80 requirements, ensure that the actual energy saving effect of completed civil building energy saving project reaches the design standard. In accordance with the requirements of "Notice on the inspection and evaluation of the completion of civil building energy saving in Shanghai (trial)” Shanghai construction and safety quality supervision [2009] NO.029 and other specifications, before the final acceptance, the construction unit should collect and organize related design drawings and data in accordance with the relevant provisions, entrust the city energy efficiency assessment agencies acknowledged by the construction administrative department , test and calculate the building energy consumption, the efficiency of energy system and other performance and judge whether or not the building energy efficiency is to achieve energy efficiency design standards. If the results fail to meet the standards for energy conservation design, the project shall not be completed for acceptance. The entrustment contract shall be submitted to the quality supervision station for record.

    The scope of energy efficiency measurement:
    1) Newly built (rebuilt or expanded) office buildings of state organs and large public buildings (with a single building area of more than 20,000 square meters);
    2) New large residential projects (the total construction area of the same project is more than 300,000 square meters);
    3) Office buildings of state organs, large public buildings and residential buildings that implement comprehensive transformation of energy conservation and apply for state financial support;
    4) The construction apply for of national or Shanghai energy conservation demonstration project;
    5) Buildings that apply for green building evaluation marks.
