Abstract:
The energy supply for temporary construction site accommodation represents a challenge that has been neglected to date in terms of sustainability and efficiency. This paper examines the energy supply for temporary construction site containers using a two-story container complex with 20 units as an example. The aim is to develop and evaluate sustainable supply concepts to cover electricity and heating requirements, taking into account a recyclable material strategy. The central basis for this is the experimental unit Urban Mining & Recycling (UMAR), whose material approaches are analyzed and evaluated with regard to their transferability to construction site containers. Three variants were designed for energy supply: a combination of a PV system, heat pump, and battery storage (short-term storage) and two concepts with seasonal long-term storage based on green hydrogen and methanol, respectively. The variants were evaluated in terms of their energy self-sufficiency, CO₂ balances, and economic efficiency. The study shows that the integration of renewable energies and a recyclable construction method can achieve a significant reduction in fossil fuel dependency and an increase in resource efficiency.
