When it comes to going green, the hotel industry is a little behind the commercial and residential movements but they are definitely trying to make a comeback. Part of the problem was the cost involved to retrofit an existing hotel with green components. Sometimes its just easier to start from scratch, integrating the energy efficiencies into the structure from the beginning. But as the cost to green continues to decline, hotels are finding a treasure at the end of their of income statement in the form of higher rents and lower operating costs. Even Kimpton Hotels are joining the green fray with their EarthCare program, which focuses on using environmentally friendly cleaning supplies, recycled paper, and energy and water conservation (visit their website here).
