I'm a Senior Lecturer at the Robert Gordon University experienced researcher in the areas of environmental design, Energy performance in the Built Environment and visualisation. My work has been widely published and acknowledged nationally and internationally through awards the Scottish Saltire award for Innovation in Housing, the International Award for Innovation and Research from CIOB, Scottish Energy Efficiency Award. I keep strengthening the connection between my research and teaching.

Models of basic components are introduced in the Scilab Connected Object Simulator (SCICOS) package. A Scicos diagram of a single-user system is realized and time domain and parametric simulations are developed in order to compute the bit error rate of the transmission. Principles of simulation of the realized diagram using the parallel virtual machine toolbox are then given

EnergySave interface captures the essential elements of a design in an unambiguous way to enable a valid energy analysis at the concept stage of a design. The use of a detailed thermal model at both this stage, and later stages in the design process would bring a consistency to the analysis throughout design. EnergySave interface provides a mechanism to bring simulation to those who believe it to be too complex for their needs and difficult to use. It does not ignore external shade and does not encourage users to be obsessed with complex representations. The form of the building is simplified, at present to a rectangle. It is important to realize the EnergySave does not contain a calculation engine. It is intended that the XML file be described in sufficient detail to allow the use of third part engines.

The government through Public-Private Partnerships (PPPs) has attempted to increase the shares of solar generation to augment its efforts in reducing the energy deficit of the country, especially in remote and off-grid communities. However, the extent to which PPP has been utilized as a viable tool for solar sector development in Ghana is questionable. This study discusses the current state of PPPs in Ghana’s solar industry and compares how it has been efficiently used as a tool to promote the solar industry in South Africa and Morocco. Fundamental theories such as Altruism, Game, Principal-agent, and Pareto Optimality (PO) were used as analytical tools to examine how PPPs are handled in the selected cases. The study ascertains that the Game and PO are applicable theories that have guided SA and Morocco’s solar infrastructural development. This study discovered that P...

This article is from Forum 13, Historic and Vernacular Buildings and examines the topic of historic building and refurbishment. The majority of the buildings that will exist in 2050 are already built. The greatest challenge we face today is to ensure that these buildings are brought up to a standard that can not only ensure they continue to provide safety and comfort of their occupants over time but also that the energy used to do so does not have too great an impact on our climate and environment.

This challenge has embarked the whole nation in a national exercise that involves professionals in all sectors, corporations, SMEs, families and individuals. The nation meets every day with new tasks, initiatives and incentives designed to meet that target. The built environment is one aspect of this multi-faceted exercise and within the built environment itself many aspects are being tackled. This paper evaluates the current legislations, initiatives and incentives introduced in the UK to reduce the energy demand in the Built Environment and how they contribute to meeting the UK's international obligation in cutting CO2 emission. Incentives such as feeding tariff for renewable energy, Green Deal for upgrading buildings and many other initiatives; have been withdrawn, revised or replaced after their excessive success or unexpected failure. These actions reflect the lack of clear plan ...

Built upon principles of social practice theory, the results presented here compare and contrast occupants's daily practices of comfort with the physical characteristics of the indoor environment. Specifically, this study explores the effect of coping with discomfort on the internal moisture loads (difference in water vapour content ing/m3 between indoor and air). A cross-sectional study was designed to gather qualitative and quantitative data from households of traditionally constructed buildings before and after a thermal retrofit of comfort (such as heating or ventilation) are shaped. More importantly, the comparison between narratives and measurements showed that households where comfort was more difficult to achieve were those with higher moistrue concentrations. The results of the study also showed that the adjusting mechanisms chosen by the users - that is, the way in whi...
