The Naruwan Hotel in Taitung, the Lees Hotel in Kaohsiung, and the Fisher Hotel in Tanshui have gone a bit further in regard to energy conservation. The Lees has replaced traditional boilers with a heat recovery system that uses a converter to heat water for its guest rooms using heat radiated from air conditioner compressors.
台東娜路彎飯店、高雄麗景酒店、淡水漁人碼頭休閒旅館在節能上著力較多，例如麗景採用熱回收系統，將冷氣壓縮機散發的熱氣，透過轉換系統為水溫加熱，供應全部客房熱水，取代傳統的鍋爐燃燒。
