The Husky Injection Molding Systems Ltd. ,Canada, has planned a technical center for machine engineering and a two-storey office building in Shanghai, China. Weather conditions in Shanghai range from warm
with extremely high humidity in the summer to more moderate in the winter, where the temperature rarely drops below zero. Both buildings require a foundation of 40-meter piles, as the soil consists essentially of wet clay.

Energy Concept
During the winter months, a cooling tower provides cooling into the soil, which then stores it until the summer. The soil beneath the buildings acts as a seasonal cooling storage. The piles are used as heat exchangers. Dehumidification is carried out by a desiccant dehumidification process, driven by the district heating system. It has been possible to reduce primary energy consumption to auxiliary energy consumables such as pumps, cooling towers and ventilators by using the soil as a cooling storage and using district heating to cover heating needs. By using district heat from a co-generation process, as well as the avoidance of chiller for cooling purposes, CO2 emissions to run the building are about 15% - 20% compared to a standard design.
