Data Overload
Information on operating parameters of services systems in large buildings and building complexes can overwhelm data systems tasked with evaluating and systematizing the input.

Facility managers and engineers wanting to...
Contraband Refrigerants, a Future Threat
The black market in counterfeit refrigerants began when CFCs were being phased out.

Today over 80% of households use electrically driven heat pumps as the principal means of space heating and most are based on ground-source evaporators....
Chilled Beams in UK
Fan coils are often chosen by developers of speculative office blocks as the fail-safe alternative to chilled beams because they offer an easy solution in dividing up the letting spaces.

For example it will be low in the Building Research Establishment Environmental ...
AHUs in Germany
Over 75% of the air handling units (AHUs) being sold for the commercial sector in Germany are relatively small units rated at less than 20,000 m3/h. The trend is to use so-called compact packages rather than custom- built units which were favored in the past. These units follow the ‘plug-and-play’ concept where all essential components are built in and prewired. Typical of today’s products ...
