Ruth, pineapples (bromiliads) can live in cooler temps in winter..just be careful with the watering.
Wow, how do you live in 60 degrees temps? LOL I'd be freezing my bu** off..lol..Guess the gas company doesn't like your business...(S) Toni

It will survive but it needs higher temps to set fruit.

electric too costly, reaches 85 in summer, winter only prob

Mine set small fruit (3 1/2inch diameter) in the UK this year. Must have only been about 60ish at the time of fertilisation. Went up to 90 later in the year, now down to about 70. Don't think it will manage ripen though - still green.
