Energy efficiency is important both to reduce costs and to reduce greenhouse gas emissions in the atmosphere. Reducing costs will also help maintain business competitiveness. Scania in Södertälje is a company where the optimization of energy use is an ongoing and continual process. One area with potential to make energy and cost savings is the effectiveness of the ventilation systems in offices and industrial premises at Scania. During the summer months an increased demand for cooling occurs, leading to increased ventilation and a peak in district cooling system usage. Sorptive cooling is a technology where the supplied air is cooled by applying external heat. This technique involves a reduction in electricity consumption compared to electrically-powered cooling machines and does not affect the district cooling system usage. It was therefore of interest to investigate if sorptive cooling would be an energy efficient and viable solution for Scania in the future. This investigation shows that sorptive cooling requires more power than a conventional ventilation system. Despite the fact that Scania has access to free heat during the summer months, the study shows that sorptive cooling would not be economically viable to install in the industrial premises, where no cooling systems currently exist. However, compared to an electrically-powered cooling machine, sorptive cooling is anyway more energy efficient. The conclusion is that sorptive cooling is a viable solution for the offices, but not for the industrial premises at Scania in Södertälje
