Improvements in construction project management competencies are essential to helping the construction sector to embrace the new challenges. Building engineering management capabilities through the correct training are therefore essential. In research involving the twenty-four largest contractors in Australia ‘Lean construction’ was identified as an important skill to be included in academic programs that has not yet fully been embraced. Contractors are not yet seeing ‘lean’ and ‘agile’ methods as important approaches to improve communication within the teams and between projects. This research highlighted that although contractors identified communication as one of themain skills needed to achieve a good performance in project construction management they do not yet recognise that training in lean and agile methodologies will help them to improve communication not only between professionals but between projects and organisations involved in each project in improving business goals.
ItemChapter 37: Heat PumpsAye, L ; Fath, BD ; Jørgensen, SE ; Cole, M (CRC Press, 2020-07-29)In this second volume, Managing Air Quality and Energy Systems, the reader is introduced to the general concepts and processes of the atmosphere, with its related systems. Heat pumps capture heat energy from low-grade heat sources such as ambient air, ground, and waste heat streams and upgrade to a higher temperature level for useful applications. This entry includes a brief history, fundamentals, classifications, applications and performance parameters of heat pumps. Working principles of the thermoelectric heat pump, the absorption heat pump, the gas compression heat pump and the vapor compression heat pump are explained. Performance parameters of the heat pump systems (coefficient of performance, energy efficiency ratio, primary energy ratio, and ambient energy fraction) are presented. The short-term and long-term greenhouse gas saving potential for the use of heat pumps are discussed.
ItemNo Preview AvailableGreen Buildings in Makassar, IndonesiaHui, K ; Ulya, PF ; Wilson, S ; Meyliawati, A ; Aye, L ; Gou, Z (Springer Nature, 2020)Indonesia has one of the world’s largest populations, which creates a demand for buildings. Construction and operation of buildings have impacts on environment. To create sustainable cities, Indonesia applied the smart cities concept and selected Makassar as one of three role model cities. This chapter explores the current situation in Makassar with respect to green building adoption, the challenges faced and opportunities in market transformation. The Green Building Council of Indonesia (GBCI) in Makassar is heavily involved with market transformation for green building practices and has four main activities: market transformation, training and education, green building certification and stakeholder engagement. GBCI has developed the GREENSHIP rating tool, an assessment system covering categories associated with the green building concept as it applies to Indonesia. The embracing of the green building concept, however, is still low in Makassar. Market transformation is a challenging task, and there is still a lack of formal education programmes and courses available to architects, engineers and the construction industry to drive the transformation. The initial higher cost of green building presents as a major barrier to the uptake of green building even though these costs are mitigated after a period of 4–5 years through a reduction in operational costs. Government regulations that support green building practices and education of the community about the benefits of green building may support/improve uptake of green building.
