Abstract

Greenship Interior Space is a rating tool used in ensuring more sustainable and healthy indoor space with the focus on the health and comfort of the users thermally, visually, and acoustically. It is important to study this concept further to ensure a healthier workspace where most workers spend 80-90% of their time. This is necessary because a well-designed Indoor Health and Comfort has the ability to prevent the emergence of Sick Building Syndrome and increase employee productivity. This research was conducted using the Ciputra University workplace as a case study. Moreover, a descriptive quantitative approach was implemented with data collected through observation, interviews, and field measurements. The results showed the possibility of optimizing the visual comfort and outside view in the workplace to obtain the appropriate level of illumination and to improve workers’ productivity. This, therefore, means, a workplace needs to address the environmentally and socially conscious behavior and also support employee performance in order to improve productivity in line with the strategies of a green workplace.

Abstract

The availability of non-renewable resources to generate electrical energy has decreased. The National Energy Council says that Indonesia has huge potential renewable energy resources. The largest amount coming from solar energy. However, only 5% is utilized. The number of building owners who want to install the technology related to renewable energy on/in a building in Indonesia is still very small. This happens due to the high initial cost of installation. In case of an existing building, the boundaries added with the limitation of structure and limitation of potential-available integrated area. This study proposed a BIPV model in an existing building to contribute the maximum use of renewable energy in a relatively limited potential-available integrated area. The experimental method was applied to several models. Amount of electrical energy generated, and ROI were used as optimization parameters. ROI will give more comprehensive review to a building owner, to show that the time period is the most critical determinant of investment. The study shows that installation of PV on an opaque wall in the west orientation is the optimum one. The model generated 777741 kWh/year of electrical energy, exceeding the existing consumption. ROI calculated in 4.36 years, relatively short compared to 25 years of PV life guarantee. The optimization on this model is supported by its largest number of integrated area and high annual radiation received. This study shows significant results to the building owner. Electrical energy and ROI should be fully taken as a consideration of when to decide to apply PV.
