Embodied energy of mechanical services systems
This paper presents the findings of an Arup research project into embodied energy of mechanical systems. The project took a theoretical 80,000m2
commercial office development, and developed two typical mechanical services designs to schematic level – a low-temperature variable air volume system (LTVAV) and a hybrid LTVAV/fan coil unit system. The team then undertook detailed embodied energy calculations for the two systems in order to quantify the embodied energy, using Arup-developed calculation tools.
The intent of the work was to develop reference figures for use at a conceptual level, understand availability of metrics, and refine the process of calculation. The paper will outline the approach, methodology, and conclusions to this research work, and provide recommendations for further research and advocacy.
