It is one of most important factors to achieve appropriate Indoor Environment Quality (IEQ) in order to enhance occupants' health and productivity in office buildings. Among various indoor environment factors, it is generally believed that the effect of thermal environment is most significant for the occupants' comfort and productivity. To provide satisfactory thermal environment, it is general to design HVAC systems which can satisfy indoor environment criteria specified in relevant guidelines or owner's additional requirement. However, it is often in the design stage that thermal environment criteria is presented insufficiently and owner's requirements are not specified while the owner demands high level of environmental quality. In this study, thermal environment was assessed for the office building occupied by the owner's employees in order to derive a design and operation strategies, under the condition that the owner's requirements for thermal environment are not addressed specifically. The assessment was carried out for the typical office space of headquarter of 'M' company in Ulaanbaatar, Mongolia. It is expected that the design and operation strategies to improve thermal environment can be derived by applying the result of this study to new or remodelling projects.
