The challenge of a tropical "holistic" Passive building is to bring ALL those relevant parameters into play in different seasonal and weather situations whilst expelling the interference of the hot outside air. In principle, this is happening anyway for most commercial buildings and Passive Houses in all other hemispheres alike, but it is not common for tropical residential building strategies. The author refers back to a database of 250 days from a suburban area in Malaysia. Data out of 4 typically hot months in the year 2017 in detail with 3 adjacent real mini-residential Passive and 1 "red" House(s) with the same positioning for ambient temperature and the most vulnerable part of the building envelope which is t...

Since 2008, tools for countries in the Northern "colder" hemisphere have been adapted to tropical countries. In contrast, the Tropically Adapted Energy Performance Certificate (TEPC), established in 2012, translates the United Nations' triple bottom line principle into green building sustainability (planet), thermal comfort (people) and affordability (profit). The tool has been especially developed and revamped for affordable green building assessment helping to reduce global warming. Hence, by the comparably simple and transparent energy audit it provides, the TEPC examines buildings for their: (1) contribution to reduce CO2; (2) transmission rate in shielding a building's envelope against the effects of the tropical heat; (3) generation of thermal comfort and (4) referring total cost of ownership to green the building further. All four dimensions are measured in the rainbow colour scale in compliance with national energy regulations. Accordingly, this research examines the tool's implementation in tropical countries. Exemplified tropical case studies in residential areas seek to demonstrate the practicability of the approach and to derive a holistic certification by an internationally accredited certification board.

Looking at the worldwide map of residential buildings’ contribution compared with commercial, the worldwide national maximum of 33.5% CO2 of housing is caused by residential buildings in Uzbekistan. In an overwhelming number of most countries, their values are significantly lower, due to comparably lower energy demand than commercial buildings and because affordable homes increasingly use small PV to cater for their own basic needs. However, with the rising temperature and a likewise growing imperative to cool homes from about 30 °C onwards basically by split-unit air conditioners, the residential houses’ portion of CO2-emission might dramatically increase to survive such more common hot periods in the future. In combination with air conditioners needing some airtightness, the first purpose of this entry is to show that ...

In der Sprache der betriebswirtschaftlichen Kombinationslehre ist dieser Zusammenhang im folgendem Lehrsatz formuliert: Durch den Einsatz von Gutern (Vorleistungen) bzw. Dienstleistungen soll ein Ergebnis erzielt werden (Ertrag), das den Betrieb erhalt oder seinen Gewinn maximiert.
