I do not have any experience with growing orchids in the house - apart from shop phallies . Most of the oncidium alliance are thin-leaved, and need fairly low light ( so a house is likely to be OK ) but also need constant high humidity ( which is the killer ). If you really can give it a light spray a couple of times a day, then maybe...
Most of these intergeneric oncidium types are not at all seasonal - they flower when the growth is complete, and if given reasonable treatment that can happen on a say 10 month cycle, so it will flower probably only once a year, but at a different time each year.
The Dutch gow them in a coarse soft peat-like stuff ; I have used bark/perlite/charcoal- 4:1:1 successfully, also bark/perlite ( medium bark, 2:1). Currently I grow in coarse well-washed Perlite, standing in water . Water means a nutrient mix at say 500EC and 6.0 pH.
It was said that pure odonts (crispum) could be grown down to 48 F in the winter ; Oda types needed 52, and Odtnas 55 . No-one ever said what Vuylks wanted, but the Milt addition suggests a bit higher - say 58, and when I said a house should be Ok I am making assumptions....
I never turn the central heating off - the thermostat will bring it on if the house drops below say 72 ; my brother doesn't turn his on until October 1st, and sets it at 55.....which shows how dangerous my advice could be !
But maybe you can get something from all of this ? I hope so.
