Global energy consumption is rising and the relative contribution of lighting in buildings to that total is also increasing. In offices, the dominant form of lighting is fluorescent, but this will soon be surpassed in terms of performance by LED lighting, which are already starting to be more widely used. Considering that most buildings and offices are of older building stock, this presents a great opportunity for making energy savings by using more efficient light sources within offices. This thesis investigates the application of LEDs as a retrofitting solution to existing fluorescent lighting systems and assesses their potential to provide an equivalent lighting environment with no adverse effects on performance and investigates their impact on space conditioning load demands and CO2e emissions on a range of case study buildings in the UK. Savings in lighting cannot only be made through reduced electrical consumption, but also through space conditioning loads, by reduced lighting heat gains. Currently used lighting technology is reaching its limit of performance, whereas LEDs offer the potential to meet energy saving targets with their rapidly improving performance. LEDs emit most of the heat generated to the back of a luminaire, rather than directly to the occupied space and this can lead to reduced heat gains and thus savings on space cooling demand loads, in addition to the electrical savings due to higher efficacies, for operating them. In this thesis, simulation software were reviewed that would allow for the lighting specification of custom LED replacement luminaires and assessment of their thermal performance. Methodologies were developed on simulating their light output and designing custom LED replacement luminaires with the use of RADIANCE, thus providing a novel use for this extensively used and validated software. For validation purposes a test room was used where custom LED replacement luminaires were fitted and measured for their performance, where good agreement in predicted and measured results was found. A visual performance study was also conducted using a range of age groups, to ascertain if there is a difference in task based performance on paper and VDU screens between fluorescent lighting and LED lighting, in an office environment. Subjective opinions on preference between the two light sources was also investigated. An assessment of space conditioning load demands was performed on five case study buildings, where custom LED luminaires were specified to retrofit the existing fluorescent lighting. Results showed lighting levels and distribution in each building could be replicated with good agreement, offering a cooling load demand reduction, however with an increase in heating load demand. In terms of CO2e emissions, the use of LED lighting instead of fluorescent also proved to be beneficial, providing reductions in emissions.

Education in South Africa is experiencing challenges of interest in its learners towards science and mathematics within the primary and secondary phases of learning. The result of this failed interest is represented by the amount of scarce skills present in the technology, ICT and engineering sectors, resulting in a lack of research and development of current and future technologies. The solution to this problem is to create a lateral approach through learners’ interests by using performance media as a medium of instruction. This intervention is established as part of the University of the Witwatersrand where it will serve as a crucible of research, exploration and education of science and technology through cross-faculty co-operation. Using the University’s vast academic and educational resources, this intervention will become a staging ground for new scientific and technological development conveyed through a variety of performance mediums which will be presented to learners, students and the general public. Situated adjacent to the Parktown Education Campus, this facility is the beginning of planned expansion by the University linking its various campuses through Braamfontein civic district. The site has an important historical and heritage association with Johannesburg - through its heritage landmarks - and by its use through the National Children’s Theatre. Whilst this has been a site for performance art over the last two decades, the expansion and integration of this building will continue this legacy into the future through the exploration of new and dynamic performance mediums. / 2014 Thesis - M.Arch(Prof.)
