This is golden pothos, a variant of Epipremnum aureum.
The plant is very easy to grow. I think the reason for brown leaves is direct sun, its not very tolerant, esp if its dry heat. Try to put in shade/indirect light, even indoors is ok. It grows very well in high humidity. It need good watering and is very forgiving to standing water as well. Frequent misting is taken well.
One of the very hardy plants and easy to maintain. Use common garden fertilizer once a month perhaps.

This is normally grown as a house plant. Is it warm enough on your balcony for it?
