Efficient cooling and heating of office buildings in the UK by means of TAB system and its life cycle cost compared to other HVAC.

Summary

Thermally-Active Building (TAB) System is a combined cooling and heating system with pipes embedded in the structural concrete slabs or walls of multi storey buildings. TAB system operates at temperature close to ambient which facilitates the integration of renewable and free cooling sources. Although the TAB system is a mature and well proven technology in Central Europe due to energy savings and low investment and operating costs compared to other traditional air-based technologies, there is still limited evidence in the UK. The present study compares a life cycle costing analysis of an office building with the TAB system to traditional convective air conditioning; fan coils, displacement ventilation and chilled beams. The life cycle costing (LCC) analysis shows an assessment of different methods of supplying heating, cooling, and ventilation. The result showed that choosing Uponor TAB system for the HVAC scheme will improve the quality of indoor environment (PMV index in class A range by 25 to 39 % more occupation hours in two selected rooms), and will decrease the global cost for the building (investment including depreciation, running and energy of a mid price escalation) significantly by 12 to 31 % compared to other air borne HVAC mechanical schemes. In conclusion TAB system has proven adaptable and cost effective for the UK conditions.
