“Habitat 5.0 – Towards affordable and sustainable housing in the developing world” strives to build communities by following urban design patterns for sustainable settlements and goes beyond the mere production of individual housing structures. It is a blockchain-based approach that leads to “disruptive innovations” in order to achieve “quality good enough”1 to upgrade informal settlements. The key approach relies on the secure and verifiable transfer of existing, qualified knowhow that enables residents to participate in the process. The self-building of houses with ecological materials is safer, cheaper, faster, sustainable, and supports the vision of “Glocalization.” Habitat 5.0 is a need-based approach: The need is the lack of affordable and adequate housing which leads to the surge in informal settlements. The idea is to improve informal housing in situ. This need is aggravated when disasters strike, as informal settlements are the most vulnerable when heavy rainfall, floods, storms or earthquakes hit unstable land and unsafe structures. Apart from informal housing, many other cheaply built structures are usually affected and destroyed by natural disasters. Therefore, disaster relief housing is another major potential of this approach.

In the article, the electrical and thermal processes in the LED lamp with varied parameters are investigated. Voltage and current measurements on all LEDs of the luminaire are carried out in the nominal operating mode. The power allocated to each LED is determined. The calculation of the LED crystal temperature was carried out using the developed thermal LED model based on the results of the measurements and by using “Multisim” program. It has been established that the temperature of the crystals of individual LEDs in the luminaire differ significantly, which leads to unfavourable thermal conditions for them and an increased likelihood of premature failure.

 Elevated CO2 rates in a building affect the health of the occupant. This paper deals with an experimental and numerical analysis conducted in a full-scale test room located in the Department of Mechanical Engineering at the University of Technology. The experiments and CFD were conducted for analyzing ventilation performance. It is a study on the effect of the discharge airflow rate of the ceiling type air-conditioner on ventilation performance in the lecture room with the mixing ventilation. Most obtained findings show that database and questionnaires analyzed prefer heights between 0.2 m to 1.2 m in the middle of an occupied zone and breathing zone height of between 0.75 m to 1.8 given in the literature surveyed. It is noticed the mismatch of internal conditions with thermal comfort, and indoor air quality recommended by [ASHRAE Standard 62, ANSI / ASHRAE Standard 55-2010]. CFD simulations have been carried to provide insights on the indoor air quality and comfort conditions throughout the classroom. Particle concentrations, thermal conditions, and modified ventilation system solutions are reported.
