I would not worry about the leaves, they look fine to me, and loosing old leaves is a natural process.
As rbarata noted, the roots I can see on top are very dried out (they won't plump back up). But it looks like there may still be viable roots below. I would suggest watering more frequently. Orchids are used to growing in very humid environments so you really do not need to be too careful about letting the media dry out.
My recommendations: Close the window! If you don't have the heat on, your orchid will prefer having the window closed. When watering, water thoroughly until the roots in the lower part of the pot look green, letting water drain through. Then water again when the roots look whitish again, but do not wait until the media is 100% dry. Usually orchid growers water when media is "nearly" or "just" dry, i.e. when it is still slightly damp in places but not waterlogged anywhere. With your media, I imagine this should mean watering at least once a week, possibly every 5 days or so. I think that with more frequent watering your orchid should be fine. The leaves are healthy, and it will eventually put out new roots!
