Heat & Weather Protection for tropical climate
The main challenges in tropical climates are mold and algae formation due to condensation and high air-conditioning consumption due to heat load. To meet these challenges, Bioclimatic Solutions materials combine the right balance of heat resistance, water resistance, mold resistance, and the right level of vapour permeability.
Bioclimatic Solutions were nominated as the world’s first and only Green Insulation (GREEN APPLE) certified insulating materials, being adopted by the SPEC GREEN platforms in the UK and GERMAN ENGINEERS ASSOCIATION and they are ISO 9001:2000, CE, TSE, ERA, TCL, JAS_ANZ, TÜV PSB and SETSCO certified.
Passive cooling is a building design approach that focuses on heat gain control and heat dissipation in a building in order to improve the indoor thermal comfort with low or nil energy consumption. This approach works either by preventing heat from entering the interior (heat gain prevention) or by removing heat from the building (natural cooling). Natural cooling utilizes on-site energy, available from the natural environment, combined with the architectural design of building components (e.g. bioclimatic envelope), rather than mechanical systems to dissipate heat.
Passive cooling covers all natural processes and techniques of heat dissipation and modulation without the use of energy. The techniques for passive cooling can be grouped in two main categories:
- Modulation and heat dissipation techniques allow the building to store and dissipate heat gain through the transfer of heat from heat sinks to the climate. While high thermal mass materials work best in hot-dry or temperate climates where there is a significant change in temperature between night and day in the tropics can be detrimental. The cooler night temperatures flush out the heat stored in thermal mass during the day, and the cool stored in the mass over night is released into the building during the day
- Preventative techniques that aims to provide protection and/or prevention of external and internal heat gains. Warm nights in the tropics mean that heat is not flushed from the thermal mass and instead radiates back into the building. Use of high thermal mass construction materials is therefore generally not recommended in the tropics. If high thermal mass materials are used, the building should be well insulated externally & internally to avoid heat gain and to reduce heat transfer.
