Cai adds that the implementation of those mandatory installation requirements is to be carried out by the respective Construction Bureaus. So-called Construction Document Evaluation Centres review the construction documents. If the solar water heater systems are in line with the specified requirements and technical standards, the centre will issue a certificate to the developer. Only this certificate will allow the builder to apply for a building permit. The construction site, including the solar water heater installation, will be inspected regularly by the local construction bureau. The inspection following completion of the structure will include an energy efficiency check of insulation, shading and solar water heaters systems. If all regulations are fulfilled, the developer receives a certificate which enables him to apply for a sales permit.
