A solar chimney is designed and tested to pump outside air through an underground cooling tube during summer for building cooling. Both theoretical analysis and experimental results show that the solar chimney can be used to power the underground cooling system during daytime without use of electricity. This paper presents the theoretical design principals of the solar chimney, detailed experim...

CubeSats are recently adopted for increasingly advanced mission profiles, e.g. as base for tests of solar sails or formation flight. This also leads to higher power demands on-board of the satellite. Currently most CubeSats are equipped with solar cells on their surface. Some satellites also employ additional deployable solar panels with a fixed end angle to meet the increasing power demands. F...

This work proposes a novel generative design tool for passive grippers -- robot end effectors that have no additional actuation and instead leverage the existing degrees of freedom in robotic arm to perform grasping tasks. Passive are used because they offer interesting trade-offs between cost capabilities. However, designs limited types shapes can be grasped. use rapid-manufacturing optimizati...

The objective of this study is to investigate the climate characteristics of Indonesian regions using an Olgyay Bioclimatic chart, a Givoni–Milne Bioclimatic chart and a Mahoney Table as the pre-design stage in the development of a passive house design standard for residential house construction in Indonesia. Jakarta was the city chosen for deep analysis, because it represents most of the Indon...
