Salatiga Creative Hub with Integration Concept of Double Skin Facade and Passive System for Energy Efficient Building Envelope in Tropical Climate

Abstract

Salatiga is a small city with many young adult and college student having problems in finding work in the city. Due to the small area, not many office or big company having branch there, making it hard for young adults to work in their hometown. Creative Hub is a solution in which providing working environment for people to either work remotely, having rentable space for companies to rent, or as a space to promote people’s art through exhibitions. The many usage of Creative Hub is needed but the avaiability of the function should be adapting user’s need. If there is an event then the building should be able to held it but if it is just a normal day then the space should be adapted to co-working space for example. The adaptability of building space to accomodate different functions is essential to have high-performing Creative Hub. The integral part of building which cause many old building needs to use Air Conditioning System and Artificial Lighting during daytime is non-optimized building envelope design. Double Skin Facade System is one of the form of designing building envelope to enhance passive system such as cross ventilation system, daylighting, and such to be optimized in energy efficiency. Energy efficiency is one of the solution to reduce the impact of global warming – especially in reducing the usage of Air Conditioning System and wasteful daytime Artificial Lighting. Salatiga though still has an advantage in located in slope of mountain is that the natural wind current is quite strong from upper part of the mountain which can be used to cool of building temperature naturally with good ventilation system – which usually called as cross ventilation system. Daylighting can also be implemented additionally to even further improve energy efficiency. In results the building will be energy efficient or atleast energy saving in terms of electricity usage of cooling and lighting due to the optized of building envelope.
