"COMPARISON OF FAN COIL UNITS AND CHILLED CEILINGS"
In this cost model, covering mechanical and electrical installations, Aecom's specialist MEP cost managers examine the capital cost of fan coil units and chilled ceiling installations to a CAT A office within central London, to a single floor plate covering 1,600m2 net internal area.

NEW - HEVAC position statement on SFP for fan coil units
Specific Fan Power of Fan Coil Units has recently become a very significant number within project specifications. This FCU Group position statement sets out the current thinking (December 2014).
Following a previous study where fan-coil units (FCU) and active chilled beams (ACB) were compared under different operating conditions, the HEVAC Fan Coil Unit Group in FETA commissioned EDSL to compare their relative energy consumption under the same operating conditions. For the results and the report ............
There is an article on the study in the Sept 14 CIBSE Journal - link is http://portfolio.cpl.co.uk/CIBSE/201409/special-fan-coil-units-efficiency/
A PDF of the article is available from here, but the above link is better resolution.
The aim of the HEVAC Fan Coil Unit Group is:
To promote the effective use of Chilled Water Fan Coil Units within a buildings environmental system by supplying meaningful and definitive specifications from which engineers can make considered decisions.
Why use Fan Coil Units? Guide written in 2011
The FCU Group has produced a short leaflet to bring to your attention the many advantages of fan coil unit systems, which are summarised and compared with the attributes of alternative systems.
In November 2009 the Fan Coil Unit Group produced a good practice guide to acoustics for fan coils. Containing case studies and worked examples of installations it gives advice on system components, the effect they can have, and the associated pitfalls that can occur, especially in relation to small scale projects.
Achievement of Aim

Do FCU comply with the new Part L Building Regulations?
Yes they do. Members worked closely with the DCLG when they developed the new Part L in 2006 and they all supply fan coil units that comply with the regulations.
Some end users have had difficulty in understanding the requirements for Specific Fan Power (SFP) under the new Part L. To help, the FCU Group had prepared the following position statements:
CIBSE TM43 - Fan Coil Units
This Technical Memorandum, which at Ecobuild in March 2011 was described by CIBSE as one of their "Best Sellers", sets out to describe all aspects of fan coil unit technology and provides manufacturers, designers, site personnel and operators a comprehensive guide.
