As one of the standards of national education, facilities and infrastructure plays an important role to improve the quality of learning, thus the good quality of infrastructure management is required to achieve the educational purposes. In tropical countries, buildings generally require approximately 45-70% of total energy consumption for air conditioning, and 10-20% for the lighting system. Since the revitalization of Vocational High School (SMK) is currently one of the concerns of the Indonesian government, the energy consumption of its buildings – mainly for the purposes of thermal and lighting comfort also receive serious attention. The objective of this research was to identify the basic criteria as an initial indicator for assessing the energy performance of building. The analysis and identification of criteria was done by using Important Performance Analysis (IPA) method. This study involved 91 respondent from 3 (three) Vocational High Schools in Medan, consisting of students and teachers. The results show that from 41 performance criteria of building design that influence thermal comfort, there are 14 indicators perceived as important by the users of vocational building building facilities, they are: (1) building location, (2) heat reduction effort around building, 3) building plan, (4) architectural form, (5) structural design and building envelope, (6) structural design and sheath, (7) interior, and (8) air conditioning and artificial lighting system.
