Sustainable chilled beam design.

Author(s) : VIRTA M., ITKONEN H.

Summary

Chilled beam technology is seen as a very sustainable technology providing both excellent indoor conditions but also an energy efficient lifetime. This is a case only when different aspects of sustainability are taken into account in entire design process. It is important to optimise architectural design of building, HVAC-system design, and terminal unit selection according to indoor environmental conditions, energy use of building as well as investment and life cycle costs. This paper presents studies of a chilled beam technology in a typical office building. It takes into account the total energy consumption of HVAC-system, lighting and equipments and discusses the possibilities to reduce energy use by changing design criteria. As an example, the primary air volume (fan energy as well as heating and cooling of supply air) is one of the most important design considerations in terms of energy use. Control of lighting is the other area to pay attention. On the other hand the pumping energy is relatively small part of total energy consumption. Different selection strategies of chilled beam have also a significant influence on both room conditions and energy use.
