Experimental Investigation of Bioenergy Properties of Local Microalgae Consortium in Brunei Darussalam
Microalgae has been considered as 3rd generation biofuel sources from last decade owing to its excellent capability of CO2 capture and sequestration, water treatment, prolific growth rate and enormous energy content. Although energy research on microalgae has spread throughout the world, there is very limited to no initiative experimental studies has been performed particularly in Brunei, given into consideration that the weather in Brunei is quite suitable for growing microalgae. The conditions include adequate rainfall, average temperature of 28 ͦC and presence of direct sunlight throughout whole year. The research work will examine the bio-energy potential of native blue-green microalgae consortium. The local species of microalgae will be collected and energy properties will be characterized. Proximate analysis comprises of moisture content, calorific value, volatile matter, ash content and ultimate analysis (C, H, O, N, S) will be demostrated through standard ASTM method. Based on the outcome of microalgae biomass characterization, the study will endeavour to blend the biomass with other type of popular bio-energy producing biomass and generate heat by combustion. The Microalgae is aimed to be as a new source of potential bioenergy feedstock for heat and electricity generation, minimizing atmospheric GHG and supplementary options to excessive fossil fuel applications in Brunei.

Development of vertical greenery systems for thermal comfort and energy efficient buildings
A recent hot topic is the introduction of vertical greenery systems that are to be considered and to be applied to architecture design and construction field for creating energy saving building, while maintaining the aesthetics of the building and its function. The vertical greenery systems indirectly will instill the nature cycle to the building environment and promotes conventional planting in the case of less vegetation around the building. In dense urban areas where the walls of tall buildings contribute the largest part of the building, the vertical greenery system holds great potential to serve as the building envelope. The proposed research aims to develop models of vertical greenery systems and to examine its effect to building energy saving. There are two main parts involved in this project: (1) a computer simulation for modeling the computational fluid dynamics of the building; and (2) replicate the simulation to scaled building models. The results obtained in this project serve as a basis for the development of greenery design for supporting the concept of building energy saving.
