Designing a smart integrated workspace to improve building energy efficiency: an Indonesian case study

The increased energy consumption in office building led to stakeholders’ renewed interests in optimizing office buildings’ energy performances, such as indoor comfort, energy efficiency, and life cycle costs. One of the most effective solutions to hedging against building operation optimization is incorporating energy efficiency measures and architectural programming early. This paper proposes a Smart Integrated Workspace Design (SIWD) framework that integrates architectural programming system using Internet of Things (IoT) technology into the Value Engineering (VE) process to assess design alternatives targeted explicitly at future smart office buildings. The use of the SIWD led to an improved development cycle linking architectural plans and engineering design. An empirical test using a large building owner, their designers, and contractors in Jakarta, Indonesia, resulted in an 18% improvement in building energy performance and quality when the design team used the SIWD framework. It is also indicated that leveraging advanced technology and incorporating familiar concepts and processes increased user willingness to adopt the SIWD in future projects. So, incorporated the IoT in architectural design and evaluated by VE made the readiness and friendly technology to all occupants to get the building efficiency and comfort unsteady.
