Application of nano insulation materials in the sustainable Built environment
(2013-11-19) Gammampila, R; Mendis, P; Ngo, T; Aye, L; Herath, N
Nanotechnology is widely being used in the built environment for its advantages in many improved engineering properties of the nano materials. Nano insulating materials open up new possibilities for ecologically oriented sustainable infrastructure development. The most widely used nano material in built environment is for the purpose of insulation to improve the energy efficiency namely in the buildings and dwellings. Nanotechnology has now provided an effective and affordable means to increase energy efficiency in pre-existing buildings as well as new construction by increasing thermal resistance. The major advantage of nano insulation materials is its benefit of translucent coatings which increase the thermal envelope of a building without reducing the square footage. The intrinsic property of nano insulating material is it can be applied to windows to reduce heat transfer from solar radiation due it its thermal resistant property and the translucent property allows diffusing of day light. The nano insulating material has significant advantage in reducing the operational energy aspects of buildings due to its valuable insulating properties. This paper examines applicable nanotechnology based products that can improve the sustainable development and overall competitiveness of the building industry. The areas of applying nano insulating material in building industry will be mainly focused on the building envelope. The paper also examines the potential advantages of using nanotechnology based insulating material in reducing the life cycle energy, reduction of material usage and enhancing the useable life span. The paper also investigates the operational energy by simulation methodology and compares the reduction of operational energy consumption.

Seismic performance of super tall buildings
(2013-11-18) Herath, N; Mendis, P; Ngo, T; Haritos, N
With the rapid population growth and dynamic economic developments, the demand for residential, mixed use and commercial buildings has been increasing significantly all around the world. Due to the excessive increase in height of buildings in this era, there is a significant impact on the methods used to analyze and design of tall buildings. There is a clear acceptance within the engineering community that the specifications given in codes of practice are not suitable for very tall buildings. General concepts, current methods of analysis and seismic performance of super tall buildings are reviewed in this paper. Further the effect of higher modes on the performance of super tall buildings is also discussed.

A Study on the Impact of Logo Color on Consumer Perception of Brand Personality in Sri Lanka.
(Department of Integrated Design, Faculty of Architecture, University of Moratuwa., 2022-11) Herath, N; Samarawickrama, S
A growing body of literature has investigated the impact of colours on the perception of brand personality. This study examines how logo colors impact the brand personality perception of the consumers by exploring the brand personality traits people associate with logo colours in the context of branding. Each colour has a personality attribute derived from the consumer’s earlier associations with the specific colours. This study first explores the impact of logo colours on the perception of global consumers from previous studies and then investigates the perception of local consumers. This research investigates the logo colour perception on six dominantly used colours in local brand logos by taking on a quantitative research approach to obtain a more generalized association regarding the logo colour and brand personality dimensions from the consumers’ perspective in Sri Lanka. Using the pioneer brand personality measuring framework, Aaker's (1997) Brand Personality framework, this research gained insight into the impact of logo colours on the perception of brand personality on adult consumers of Sri Lankan context in contrast to the global context. The results indicate minor differences between the global context and local context whereas out of six logo colours investigated, only two colours were perceived differently. This insight contributes to identifying the most suitable colours that are eligible to communicate the intended brand personalities to the Sri Lankan consumers to build a strong consumer and brand relationship.
