In quest for quality and sustainable development, it is necessary to find alternative materials, methods of brick making and house design. Bricks made in open kilns using locally available materials usually do not meet the requirements of the South African Bureau of Standards; hence it needs to add some ingredients such as fly ash to produce better quality bricks. This paper reports the effects of fly ash on properties of clay bricks that can improve the thermal performance of buildings. Bricks of different clay and fly ash mixing proportions were molded. A passive solar house was designed and constructed using fly ash bricks. Results indicate that thermal conductivity and water absorption decrease with increase in fly ash. Compressive strength was found to increases with increase in amount of fly ash. A mixing proportion of 50% of fly ash to 50% clay by volume produced a brick with the highest compressive strength, lowest thermal conductivity and minimum water absorption. The bricks were observed to have uniform size as they experience minimal burning shrinkage. These properties were found to have a significant impact on the thermal performance of the house. The mean indoor temperature swing was found to be 11˚C.

The purpose of this study was to obtained recommendations on the use of innovative building materials from the development of existing lightweight concrete designs, to decrease the building interior temperature. The research used an engineering experimental method on lightweight concrete as material tested. A profile was attached on the outer side of lightweight concrete in order to formed a shadowed effect and expected to make the building indoor temperature go lower. The result indicated that the shadows shaped by profile attached on the outer side of lightweight concrete not fully effectively in decreasing building indoor temperature. The lightweight concrete thickness affected the velocity of solar thermal radiation impact movement that goes into the buildings interior. The formation of profiles on lightweight concrete surfaces can be decrease the room temperature in at least more than 2°C. The shading was more effective if the profile form in vertical formation. The research output was a lightweight concrete prototype that was able to contribute to decrease the building indoor temperature.

“…Figure 6 shows a schematic diagram of the thermal conductivity setup. The stationary heat flow method suggested by previous researchers 31,32 and JIS R2616 33 was used. A strip heater was installed in the middle of the test kit which used aluminum plates to distribute heat, and water (flow rate of 45 mL.min À1 ) was run over the log-wall panels to remove the heat from the system.…”

The cross-section design of wood/polyvinyl chloride composite log-wall panels was studied for effects on compressive load, thermal and acoustic properties. Variation in the slenderness ratio (2, 4, 8, 10 and 12) on compressive load was also included. Two parameters of log-wall cross sections consisting of web thickness (3.5, 7.0 and 10.0 mm) and flange spacing (45, 60 and 90 mm) were also investigated. Experimental results indicated that higher web thickness and lower flange spacing of wood/polyvinyl chloride composite log-wall cross sections increased the ultimate compressive load and noise reduction. However, lateral deflection and thermal resistance decreased. Increasing the slenderness ratio of the log-wall panels resulted in lower ultimate compressive load and higher lateral deflection. Empirical equations for predicting the ultimate compressive load of wood/polyvinyl chloride composite log-wall panels in practical uses were proposed regarding web thickness, flange spacing and slenderness ratio.
