A review of the lighting performance in buildings through energy efficiency

As developing countries including Malaysia, are now moving towards sustainable development is in line with the Ninth Malaysia Plan, 9th MP, the development should be built to meet current and future needs for achieving sustainability of economic development, social and environmental responsibility for the prosperity without compromising the future generations‘ needs. Over the past five years, there has been a move away from constructing new buildings to refurbishing older and historic ones. Thus, the purpose of this paper is to review and evaluate the approach for the refurbishment of lighting as well as the existing energy efficiency policy and measures in Malaysian historical building for the energy efficiency improvement in the future. The paper takes the form of a review of literature. The main sources of this literature research are based on the articles, journals, and internet search. This study perhaps can add to the breadth of knowledge of lighting performance in the historical building from the perspective of energy efficiency. This study offers new and valuable insights to Malaysia in achieving optimum energy efficiency, saving in financial as well as reducing environmental impact.This paper has been presented at 2nd International Conference on Research in Science, Engineering and Technology (ICRSET’2014) March 21-22, 201

06221 Abstracts Collection -- Computational Aestethics in Graphics, Visualization and Imaging

From 28.05.06 to 02.06.06, the Dagstuhl Seminar 06221 ``Computational Aesthetics in Graphics, Visualization and Imaging\u27\u27 was held in the International Conference and Research Center (IBFI), Schloss Dagstuhl. During the seminar, several participants presented their current research, and ongoing work and open problems were discussed. Abstracts of the presentations given during the seminar as well as abstracts of seminar results and ideas are put together in this paper. The first section describes the seminar topics and goals in general. Links to extended abstracts or full papers are provided, if available

Emotional Qualities of VR Space

The emotional response a person has to a living space is predominantly affected by light, color and texture as space-making elements. In order to verify whether this phenomenon could be replicated in a simulated environment, we conducted a user study in a six-sided projected immersive display that utilized equivalent design attributes of brightness, color and texture in order to assess to which extent the emotional response in a simulated environment is affected by the same parameters affecting real environments. Since emotional response depends upon the context, we evaluated the emotional responses of two groups of users: inactive (passive) and active (performing a typical daily activity). The results from the perceptual study generated data from which design principles for a virtual living space are articulated. Such a space, as an alternative to expensive built dwellings, could potentially support new, minimalist lifestyles of occupants, defined as the neo-nomads, aligned with their work experience in the digital domain through the generation of emotional experiences of spaces. Data from the experiments confirmed the hypothesis that perceivable emotional aspects of real-world spaces could be successfully generated through simulation of design attributes in the virtual space. The subjective response to the virtual space was consistent with corresponding responses from real-world color and brightness emotional perception. Our data could serve the virtual reality (VR) community in its attempt to conceive of further applications of virtual spaces for well-defined activities.Comment: 12 figure
