The building's HVAC system is designed to cope with crowds of people. Each visitor or staff member is already a fairly efficient generator of heat and water, so that I don't think you will find that evaporation from a small pond will raise room humidity (although a slight very local increase may be found). Unless you have a substantial air flow over the pond's surface, and very dry conditions, your evaporation should be minimal. Check with your facilities staff on this point. My limited experience--with goldfish (carp) in an outdoor pond--was that given minimal water circulation (from a very small pump), the addition of the right kinds of symbiotic plants and snails, and the correct amount of light and food, the pond remained quite clean and essentially maintained itself. And the calming effect was wonderful! Light reflecting off the surface of the pond should not be a problem, unless you already have difficulty controlling your lighting. Your existing HVAC and lighting systems should be adequate to control the addition of a pond--your big concern will be likely be children and fools.
