Based on the existing architectural design, an energy concept aiming at high functionality and reduced resource usage as well as environmental impact was developed. Multiple advanced German simulation tools were applied to facilitate the thorough building analysis. Based on this analysis technical optimization measures in terms of functionality, energy consumption, comfort, and total annual energy cost were proposed.

The external windows orientated in South, East and West were equipped with an automatically controlled variable-angle shading system, that can be adjusted to the outdoor illumination level. In this way, the heat radiation and temperature gains in summer are effectively isolated and therefore the energy consumption for cooling is significantly reduced. Chilled beams, enthalpy heat recovery, a solar thermal system, as well as floor heating panels help to save energy and offer a wonderful indoor climate and comfort for students and teachers. LED lighting with motion and dimming controls are applied which lead to lower energy consumption of the lighting system. Compared to ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) or Chinese national standards the overall energy consumption and cost was lowered by 33%. Additionally, to the energy saving concept, the project applied a large number of water-saving technologies, including rainwater reuse, water-saving fixtures and cooling water reuse and supported the use of certified environmentally friendly materials.

About the Energy Efficiency Award

The Energy Efficiency Award 2020 – East-China was organized by the German Industry & Commerce Greater China in Shanghai (AHK Greater China Shanghai) in September 2020.

In order to illustrate the successful implementation of German technologies, products, and services in construction projects in East China, five examples were awarded and presented to a broad public audience. The selected reference projects show innovative German energy efficiency technologies, e.g. in the field of isolation, heating, and heat recovery, as well as the use of planning, architecture, and engineering services from Germany. All projects are results of fruitful cooperation between German companies or institutions and their Chinese partners.

On September 16th, 2020, the awarded projects have been published with videos and presentations of the project representatives at a hybrid event in the office of the AHK Shanghai and broadcasted worldwide through the internet.

The Energy Efficiency Awards are part of the German Energy Solutions Initiative of the German Ministry for Economic Affairs and Energy to recognise the positive impact German energy efficiency technologies have on China’s efforts to become more energy efficient.
