Improving productivity is one of those subjective areas that rarely attracts much attention, studies show that comfort conditions are critical, is it a key part of the goals for a green building, for productively.
Where the people feel their work environment is too hot, too cold, too dry or too wet, productivity drops, and in Hong Kong it is a real issue since most buildings have no winter heating.
A recent survey, by a software company, supports the notion that your workers are dissatisfaction with environmental conditions, and that in turn impacts the productivity of your business.
More detailed than other studies, this survey covers different genders, and different seasons. One finding is stands out immediately the report states 10% of staff are totally dissatisfied.
Whilst this will not be surprising to Building Services engineers who are taught that engineering systems can only satisfy 80% of the occupants in room, It is time to challenge those empirical tests, when we have better options, underfloor distribution, and smart phone computers in our pockets.
However, visit any modern building and you will still find the room sensors in odd positions, often outside the occupied zone, this strategy only provides the general/average room condition (often near the ceiling) not the conditions where the people are working.
Hotel function rooms have sensors located 6m above the occupants, so the HVAC system is working hard to main the conditions for the ceiling zone not the people zone. Also lighting fittings, hand dryers, etc. which act as localized heaters, installed beneath sensors influencing the room conditions.
