Abstract. Jakarta has implemented Environmentally-friendly buildings and Energy-saving
act policy. But the energy consumption in a building is moderately increased all the time. It
dominated by consumption in building’s air conditioner and related to thermal comfort for
building’s occupants and also the work performance of civil services employees. This
research is providing statistical questionnaire-based of subjective answers by a public
service employee of Jakarta Capital Government. This study was conducted by concerning
spatial perspective or geographic location of the object in six administrative parts of Jakarta
Capital City (center, east, north, west, south and Seribu archipelago). The questions is
spreads to 367 buildings occupants during the dry-wet season (October-November). The
study were performed in 311 Public service facility, then the data is analyzed by Partial Least
Square Structural Equation Modeling (PLS-SEM) method to answer research questions
about the link between thermal comfort and energy consumption. The results showed a
significant result between two variables. A model using those variables was generated to
show the link between them and suggested as a tool to conduct better building-related
policies in Jakarta Provincial Government.

1 Introduction
Green building policy exists in Jakarta Capital City Government since 2012, but ironically, the
energy consumption in a building is still increased all the time (Pemprov DKI, 2015). In several
types of research [1], buildings consuming energy more than 40% in general global energy, and
also provide more than 30% CO2 in general. This is mainly caused by the usage of Air
Conditioning System which impacted by building occupants' thermal comfort, especially in the
tropical region city like Jakarta [2].
Jakarta Provincial Government in this regime is eager to increase civil service employee’s
productivity (Pemprov DKI, 2017). To provide better services to its inhabitants, Jakarta
Provincial Government built standardized 311 regional offices in its sub-district (267) and
