An experimental method including objective measurements of air quality monitoring and building physical measurements was used with subjective measurements combined with academic performance and thermal comfort questionnaire. The results show average performances for a sixty percent attendance rate per class at approximately 48%-62%. The maximum daily average CO2 levels for the sample was 2,714 parts per million (ppm). This is much higher than the 1,500 ppm daily requirements. The condition of the lecture room during the summer period, based on a five point Predicted Mean Vote (PMV) scale of subjective responses of the students were found to be slightly hot, slightly humid, slightly stuffy, slightly bright and slightly noisy. A computer model produced daily ventilation rates ranging from 0.25 – 0.93 litres per second per person. This is also much lower than the required minimum background ventilation rates of 3 litres per second per person.

Biomimetics looks to Nature to see how biology has dealt with the functional challenges that face sustainable architectural design today. The author in his words – believes this approach offers one of the best sources of solutions that will allow us to create a positive future and make the shift from the industrial age to the ecological age of humankind. In eight chapters seven are devoted to answering questions about efficient structures; manufacturing materials; zero-waste systems; managing water; controlling the thermal environment; lessons from biology about light and powering buildings. The eighth chapter brings all this knowledge together into a synthesis with a concluding commentary on what does biomimicry mean for people. These chapters are a rich source of knowledge and amplified by notes and further reading at the end of the book. The book presentation is excellent with 147 figures most of them in colour which makes the book an even more enjoyable read and also a source of wonder at Nature’s way of dealing with effective, economic and optimised solutions which also are very beautiful in concept and are stunning visually. The author expresses his ideas clearly and succinctly. Not only knowledge but many case studies to demonstrate the effectiveness of biomimicry are given. His argument for much more consideration of biomimetic architecture is powerful and well made. This is a book for us all to read. Governments, local authorities and designers from all spheres not only architecture should value the considerable values this approach has to offer the world at many different scales and levels.

Further, eight challenges were identified that hinder the widespread employment of CIM including (1) reluctance towards CIM application, (2) data quality, (3) computing resources and storage inefficiency, (4) data integration between BIM and GIS and interoperability, (5) establishing a standardised workflow for CIM implementation, (6) synergy between all parties involved, (7) cybersecurity and intellectual property and (8) data management.Originality/valueThis is the first paper of its kind that provides a holistic understanding of the current implementation of CIM. The outcomes will benefit multiple target groups. First, urban planners and designers will be supplied with a status-quo understanding of CIM implementations. Second, this research introduces possibilities of CIM deployment for the governance of cities; hence the outcomes can be useful for policymakers. Lastly, the scientific community can use the findings of this study as a reference point to gain a comprehensive understanding of the field and contribute to the future development of CIM.

The development of new facade solutions which can respond to the needs of the occupants of both new and refurbished buildings is therefore a key area for development. The built environment is a major consumer of energy across the domestic, industrial and service sectors. The construction and operation of buildings are responsible for about one-third of the energy use and one-half of the electricity use in most industrialised countries. A large share of the energy use is associated with protection from the external climate and operation of systems necessary to give the occupants a comfortable indoor environment. Natural light is seen as a key driver to people’s well being both in the workplace and at a home. However, to realise high daylight factors in offices on overcast days in particular requires highly glazed facades. Single glazed windows result in high winter month heat loads, whereas modern double or triple glazed units could result in summer overheating without additional solar protection or ventilation. This paper discusses the issue of facade refurbishment or replacement in the UK for multi-occupancy buildings in both the commercial and domestic sectors. Sustainability is considered from people, process and product perspectives for traditionally glazed facades in comparison to double skin facades and climatic envelopes.
