In this paper, an experimental investigation of the integration of PCM capsules as insulation material into the outer or inner rows of hollow brick to find out the optimum location of the PCM capsules that give the best thermal performance of a wall. A test model consists of two identical cubical rooms was designed and fabricated to test the wall with and without PCM in a natural outdoor condition in Diwaniyah city in Iraq during the summer. The results show that the PCM will reduce the temperature of the inner side of the test wall and test room by 2.7℃ for the PCM capsules in the inner row while the reduction in both the inner surface temperature and the room due to the use of the capsules in the outer row was 1.9℃. The time lag for the two cases was 1 hour. So that, the inner row location of PCM is the optimum location.

Five greenhouses with different typical wall configurations were studied, including the hollow brick wall (HB), clay brick wall composed of mural column (MCCB), wall composed of fly ash air block brick (FAABB), clay brick wall composed of plum small hole column (PSHCCB), common clay brick wall with Styrofoam wall outside (SCB) to find out the effects of the north walls on the greenhouse microclimate. The interior temperature and RH environment, as well as the heating rate, cooling rate and the correlation with the outside temperature, were tested and compared, finding that the greenhouse with FAABB exhibits the optimal temperature and RH environment, and also the highest thermal stability. The findings may provide references for greenhouse construction and insulation measures.

The research aims at conducting a quality research with Reinforcement of a hollow brick wall. The empty internal sections significantly lower the dead load. With a better surface finish, the side of the block was cast, minimizing the cost of plastering. Several sample mixes are tested to achieve a finished surface. The respective frames were cast with and without reinforcement and the test results were compared. The blocks were used to build masonry walls and ' load-bearing strength ' of the walls was tested. It is possible to use the reinforced hollow block as a load-bearing wall. Nearly 75 percent of the deaths related to the earthquake in the last century,Buildings have collapsed, the majority of which (more than 70 percent)is due to the collapse of buildings made of masonry. Most of the properties in India are Unreinforced Masonry (URM) buildings that are weak and vulnerable even under moderate earthquakes and that function on the wall due to high wind forces, causing severe damage to high wind loads and it is recognized that Reinforced Masonry Building has many advantages over unreinforced masonry building.The use was very limited in Indian building practices and there are still no approved codes and shear walls were used in most constructions, even in mild earthquakes, instead of reinforced masonry walls
