Abstract

Of the total 5.9 million existing buildings, the Office occupies the 2nd position of the most types of buildings with 16% of the Total Total. The least used aspect of BIM (Building Information Modeling) is the ability to obtain building energy models using the 6D BIM methodology. This digital information model is to simulate building energy and improve building energy systems. In this way, 6D BIM simulation allows us to make building design and operational decisions. In the case of increased energy, which leads to greater quality and comfort in the sustainable use of buildings. This issue has a special relationship in public buildings. Where energy efficiency and comfort are two fundamental criteria that are highly valued by society. Once the building's energy model is prepared, it will study and identify possible ones to improve energy efficiency, as well as analyze the incorporation of other, more efficient forms of renewable energy such as the use of natural light. From this research, "10 factors that affect cost performance in Office Building Projects" Maintenance costs, Use of Photovoltaic Solar Panel Materia, Model Obyetifiability, Office Equipment (TV, Computer, Printer etc.), Use of refrigen without ODP, Use of Elevators, Initial cost of retrofit, Materia Façade, Environmentally friendly materials.

Abstract

Climate change and global warming or environmental damage and degradation have led to various natural disasters, social disasters and serious economic disasters. Global warming has increasingly affected not only our daily lives but also our business activities. Housing and settlements are one of the basic human needs that must be met to be able to live decently. However, human life and its business activities have not paid enough attention to environmental issues. Excessive exploitation of non-renewable energy beyond normal limits is also damaging to the environment.  The application of the new green  area concept is a consequence of the  increase in the cost of green areas  incurred by stakeholders so  that residential areas  become environmentally friendly, the concept of  new green areas, Value Engineering (VE), Life Cycle Cost Analysis (LCCA) are  the main factors  that influence the improvement of cost performance of implementing the concept    new green  areas in residential areas in Indonesia, using structural equation model- partial least square (SEM-PLS) analysis. This research has an update related to the concept of applying new green areas  to residential areas in Indonesia.  The results of this study obtained "10 factors that affect the cost performance of new green areas  in residential areas", namely Project Management, Infrastructure and Facilities Burdens, Infrastructure and Facilities Service Functions, Microclimate and Ecosystem Preservation, Environmentally Friendly Materials, Development, Cost Breakdown Structure, LCC Analysis, Evaluation, Value Engineering.
