Climate Responsive Building - Appropriate Building Construction in ...The main points. Provide maximum ventilation and free air movement by large openings. Provide maximum shading of direct and diffuse solar radiation. Avoid heat storage. use reflective outer surfaces. use ventilated double roofs. use vegetation to moderate the solar impact. 3.3.1 Climate and design in general (also see Chapter 3.1, General Guidelines). Climatic conditions. The climate of warm-humid zones is characterized by high rainfall and high humidity.

SuStainable tropical building deSign - Cairns Regional CouncilSustainable Tropical building Design. CAIRNS REGIONAL COUNCIL. 10. Designing for mixed-mode use. in Cairns it is feasible to design a. mixed-mode building that relies on passive, natural ventilation in cooler months and energy efficient air conditioning in hotter months. Low thermal mass materials are particularly suitable for mixed mode design, provided the building is well-insulated. Ideally passive and mechanical cooling systems should be controlled so that they cannot be ...

Building construction materials effect in tropical wet and cold ...This paper presents the results of an experimental study that was conducted in 15 office buildings in the humid and cold tropics during the working hours of the dry and rainy seasons in Cameroon. ... materials. in this study different indoor air variables were sampled. Between others, variables like indoor air speed, indoor relative humidity, CO2 concentration, and indoor air temperature were measured using a thermo-anemometer (model C.A1226) and a CO2 Monitor (model CO200).

Go Green: Sustainable Tropical Building Design - modlar.comFrom the integration of passive design measures and energy efficiency, use of alternative water sources, selection of construction materials for healthy indoor environment, consideration of lower embodied energy materials, and finally, to the restoration of ecological habitat, sustainable tropical building design mitigates

Life cycle cost of different Walling material used for affordable ...in this study, the total life cycle cost of a basic dwelling unit in Sri Lanka, made of mostly available walling materials such as Brick, Hollow cement block, and Cabook, the Mud concrete blocks were calculated by using energy accounting ... The hollow cement block is the worse building materials in tropics and its carbon footprint is comparatively higher. ... Concluding, mud concrete block is comparatively most sustainable walling material for building affordable housing in tropics.

Shaping Buildings for the Humid Tropics - Green Home BuildingShaping buildings for the Humid tropics. inSULATION: Keep attic heat out by using a vented roof and an insulated ceiling. If air can flow up inside the roof and out vents above, the roof stays cooler. Reflective foil draped across the rafters help, or insulation made of materials that don't soak up humidity. Keep coolness out of the walls: use insulation at the base of masonry walls to stop them being cooled by the soil below, which causes condensation. use light-weight or ...

How to Build In the Tropics | Dott Architecture | Tropical Modern ...6 Jul 2016 ... I have accomplished the 'tropical living' in many designs and have stayed within budget by incorporating some, or all, of these ideas and construction materials in the tropics: 1. Roof as envelope. in Costa Rica, due to it's geographical location, a home's roof is in charge of reflecting the sunlight back to the atmosphere, protecting the interior from rain and providing insulation. So here's an idea: use the 'envelope roof design', which looks like an open envelope with the ...

TROPICAL CLIMATE | Building Design Considerations Design49010 Apr 2014 ... TROPICAL CLIMATE | building Design Considerations. HOT, WET SUMMERS, HIGH LEVELS OF HUMIDITY + LITTLE CHANGE BETWEEN DAY/NIGHT TEMPERATURES. Movement of air is an important; Open up houses as much as possible; use lightweight materials for the walls and roof. So they do not store much heat and shed heat quickly; ie steel or timber stud frame with metal, timber or fibre cement claddings; Avoid Heavy mass products, such as brick and ...

How to build for the tropics JCU and Tropical Building Network ...4 Sep 2014 ... The website presents examples of buildings that suit their context and deliver on energy efficiency, ventilation and thermal comfort, ranging from small homes to large commercial and civil projects. Each case study is accompanied by enormous detail on the project's design, materials and energy use, as well as comments from the owners and users. The JCU Sustainability Fund provided the funding for the project, and individuals part of the case studies contributed on ...

Strategy for Energy Efficient Buildings in Tropical Climatecommercial buildings in a tropical climate. The literature data and the results from a case study in Thailand are gathered and a strategy for energy efficient buildings is proposed. in short, the design of the building envelope, the cooling technology and the efficiency of the appliances are the crucial factors in reducing energy consumption. This investigation shows that building energy demand could be reduced by as much as 28% through the use of low thermal conductance material ...

Passive cooling techniques through reflective and radiative roofs in ...in a study on tropical architecture, particularly on building materials, Lauber (2005) wrote that the most commonly used materials in the tropics include clay, wood, and bamboo. However, these materials are rejected by most new cities, which prefer to use concrete, steel, glass, and shiny metals. Rahman et al. (2013) indicated that affordable houses in Malaysia suffer from a high level of heat build-up, which has to be controlled to overcome the effects of global warming. Most of the ...

Earthen building in the tropics - Appropedia: The sustainability wiki12 Nov 2012 ... On the other hand, humidity higher than 60% is uncomfortable for humans. When building in the tropics, humidity less than 60% is difficult to achieve without the use of a HVAC system. Humidity mostly effects the construction period, in which the earthen building methods are required to dry. Be sure to plan in extra time to allow the materials to completely dry. While all earthen building can work in humid environments, humidity combined with other factors can often ...
