Green hotels in other countries start with the building itself by improving such things as natural lighting and natural airflow and by installing solar panels. A top-rated hotel in Austria even has its rooms underground where the constant temperature keeps the rooms warm in winter and cool in summer. The hotel also utilizes white walls and large amounts of glass in its design to compensate for the lack of natural lighting.
國外環保旅館會從建築本身做起，包括建築的採光、通風、裝設太陽能板等，甚至奧地利有高級旅館把房間設在地面下，以達冬暖夏涼、室內終年均溫的效果，並用白色牆面和大量玻璃設計來彌補採光不足的缺點。
