I think in a greenhouse enviroment (my mentor has a sizable greenhouse and they supply flowers to a well known online company's local outlet) they have used bumblebees with great success, but enjoy honeybees for both the greenhouse and field pollination. They have duel entraces though, in the greenhouse and to the outside world - the hives are inside the greenhouse, I think he has three.
The bees inside doubtfully communicate location of greenhouse food stores, they just jockey around making the most of the greenhouse and doing a good job of it. Remember though (and this is a VERY IMPORTANT POINT) honeybees are pollinators NOT cross pollinators, so there is selectivity in their trips about the greenhouse.
The number of bees that pollinate their greenhouse are proportional to the size of the harvest area, it's not like a swarm bellows in there and you have a thousand bees on every flower, you see no more bees than is necessary to do the job.
I'll have to ask what they do for the glass, I honestly don't know - I can see where some serious adjusting would be necessary in their foraging, it's sad to watch a few who follow me into the house trying to get out unsuccessfully without intervention from me. I tend to think they use some indirect shading, I'm doing my best to remember in conversations what they do have but my brain got fried a few years ago and I just can recall - I'll email him though to find out for sure.
I think having bumblebees would be neat though - our wild ones here love watching people, go about doing their business and enjoy living in my fence posts. They are like little teddy bears with wings lol.
