As stated in another answer by StephenG the day length is a challenge but I would personally disagree that the circadian rhythm is the major concern. Humans can adapt to different sleeping schedules. It would be a problem for newcomers at first because orbital period is different, but the biological clock doesn't split hours of the day as discrete values as we do when we think of time, it just does its job in setting up a rhythm for activity and a period of rest.
My concern would be more of the tilt of the planet being less than that of Earth, further increasing the average daylight time on the 30 hour rotational period.
You also have two stars, increasing the point sources of light shining on the planet, further increasing daylight time.
You have a satellite with greater size than the Moon at a similar orbit if not closer. Which will also reflect light from both stars depending on its composition, so nights will be brighter.
The stars' combined luminosity is much higher than that of our Sun.
Greater green house gas presence.
Adding to all this your note on the average temperature....
What I'm trying to get at is that even at 1.5 AU, the amount of light possibly entering the planet is far greater than that of our Earth, you might actually have a really hot planet.
The higher water surface coverage also doesn't help, water absorbs the heat from the day to keep the planet warm at night, further increasing the average temperature.
A more massive satellite also means greater tide differences at half the period of our Moon.
I guess after looking up online about Gamma Leporis, the distance is about right for liquid water and a comfortable planet, but all these other factors might just make your planet really hot and probably stormy and aggressive for any permanent residence. Also I'm not sure if the calculation was done considering a binary star system, or if the star was on its own.
Depending on your orbits of star B and said planet, you may also have situations where the planet is ~.8 AU away from the 2nd star, which might still seem far from its comfortable orbit around star B as any page on these stars states. But you still have light from star A heating the planet, so you might have periodic mass extinction due to abnormally hot weather.
I don't doubt people can find a way to live on this planet if they have to, but the solution probably involves taking advantage of the life which may exists on this planet for food. The environment needed for Earth-based crops is just too vastly different and expensive to maintain on such a planet which is already taxing for maintaining a livable space for unmodified humans.
Even if you start with Earth based crops, they may evolve overtime as only those members of the crop which have a gene ideal for survival on this planet will proliferate, the rest will just die out. Indoor farming might be out of the question if it's just too expensive to maintain the internal environment.
All this also does not involve dealing with solar activity and surviving solar flares in a system which may or may not have a Jupiter-like big brother blocking out radiation from such events. This will also effect the technology available to people outside of pre-built safe zones.
Anyway, that's my thought on the matter.
