In the article published in Energy and Building, the article focused on different systems of timber building material used in multi-story of residential building. The discussed three systems are modular prefabricated cross laminated and beam-and-column systems. Article contains the analysis of material and energy flow in production. Article analysis contain the post-use life cycle and use of the material. The studies effect has proven that improvement insulation and air tightness replacement can reduce the total energy use to 7% and 9% in beam-and-column and modular prefabricated system respectively (Dodoo, et al., 2014). The other article in Engineering Structure is focused on the HSS economical use in welded beams. Article has detailed discussion and comparison between three classes of HSS which are S700, S500 with S355.The comparison and performance specifically focused on geometrically double-symmetric I-beams and uniform pressure was applied in loading. Results have shown that HSS helps in weight reduction beams formation while S355 is the most economical class of HSS.
Concl The data interpretation was though difficult in understanding but it was difficult for those who are not from the field i.e. management teams. The overall research was effective and fulfilled the necessary demands to fulfil the required hypothesis. Result interpretation and implication were also tried to remain close to the topic.
