Nowadays, increasing of energy consumption due to global warming issues such as heat island effects has attracted the awareness of researchers, architects, engineers, property developers, and authorities to the crucial of green construction or sustainable development concept. Energy efficiency has been identified as a key consideration in discussions of this concept. In term of energy, Malaysia ranked 33rd in the list of global electricity consumption and 25th in the list of man-made carbon dioxide emissions. If energy consumption continues to increase at its current rate, domestic petroleum reserve in Peninsular Malaysia is predicted to be depleted by 2014 and Sarawak by 2020 [1]. As responding to the increasing of energy consumption, the demand of green roof technology as passive cooling technique has been recognized worldwide. Generally, by greening the rooftops in urban area, the impact on the urban climate and microclimate as well as on the indoor climate of buildings beneath them will be reduced. Therefore, this paper systematically review the concepts of green roof to give a basic understanding as global. Discussion on the benefits of this concept and its components among topic will be discussed.

The cultural connotations of the word "Islam" is analysed in this study using a corpus-based semantic prosody analysis of Malaysian newspaper reports in English and Malay. Approximately 1.6 million words of Malaysian newspaper reports published between year 2014 and 2015 were used to develop two comparable sub-corpora of English and Malay data. The downward collocations (words with semantic content, i.e. nouns, verbs and adjectives) of the word "Islam" in the two sub-corpora formed the data for analysis and Partington's (2004) categorisation of semantic prosodies, i.e. positive, negative or neutral was employed in determining its prosody. The collocational patterns of "Islam" that emerged in the corpus of study suggest that the word has mostly positive and neutral prosodies in Malaysian newspapers. The cultural connotations of "Islam" that emerged from the analysis of the Malay corpus reflect the familiarity of Islam and its inherent link with the Malay language and culture, evident from the use and naturalisation of Arabic words pertaining to Islam in the Malay language. In the English corpus, the cultural connotations of "Islam" suggest its institutionalisation in the country's education system, banking system and financial establishments. These cultural connotations are in contrast with the generally negative representation of Islam in the Western and global discourse. [ABSTRACT FROM AUTHOR]
