Energy analysis is important to analyze energy consumption pattern, monitoring on how the energy used varies with time in the building and how the system element interrelate. In this case study, a preliminary energy audit is done on lighting and air-conditioning system. The lighting and airconditioning system consume the highest amount from the total building energy usage. The study was conducted in the Faculty of Mechanical Engineering Building, Universiti Teknikal Malaysia (UTeM) Technology Campus. From the result shows  that the air-conditioning system has contributed approximately 48.8% from the total monthly energy usage. The estimation of Building Energy Index (BEI) for the cooling load is 655.19 kWh/m²/year. Meanwhile, the BEI for lighting system is found approximately 150 kWh/m2/year.

Office Lighting

A comparative field survey of the effects of two alternative lighting systems, a parabolic downlighting system and a ceiling suspended, lensed- indirect lighting system, on computer workers in a virtually windowless office was conducted. A questionnaire, collecting data on work content, perception of ambient environmental conditions including office lighting, work-related health symptoms, job stress and job satisfaction, and self-reported productivity was completed by 96 workers. Results show that the lensed-indirect lighting system was rated significantly more favorably on several subjective lighting quality scales, and significantly more appropriate for computer based work. Workers reported less problems with glare on their computer screen and with work being hindered, fewer eye problems (tired eyes, trouble focusing eyes), better productivity, and significantly higher satisfaction for the lensed-indirect system compared with parabolic lighting.

Light Interference

In an office space, an LED-based lighting system allows you to perform the function of a data transmitter. This article discusses the cost-effective design and development of a data-enabled LED driver that can transmit data along with its receiving part. In addition, this paper clearly outlines the application of the proposed VLC system in an office environment where ambient light interference is a severe issue of concern. The result shows satisfactory lighting characteristics in general for this area in terms of average horizontal illuminance and illuminance uniformity. At the same time, to evaluate real-time and static communication performance, Arduino interfaced MATLAB Simulink model is developed, which shows good communication performance in terms of BER (10–7) even in presence of ambient light noise with 6 dB signal to interference plus noise ratio. Our designed system is also flexible to work as a standalone lighting system, whenever data communication is not required.

The Creation

Architectural and artistic construction of museum is one of the most complex genres in environment development and design, with its inherent qualities, means of expressiveness, principles of environment and image development, scientific concepts, in the context of historical development, artistic styles and trends. The author of the article considers the artistic lighting design in isolation from the integral dramaturgy of the project to be deeply flawed, and the setting of accent lighting at the final stage Ц to be simple, but not outstanding. Based on extensive hands-on experience in the construction of museum expositions, the author of the article reveals some peculiarities, especially significant to the participants of the lighting system setting for museums and other cultural facilities.

In lighting design, the main concept is to achieve a healthy environment, which addresses energy efficiency, cost, maintenance, and quality. User-friendly lighting systems shall be adopted to architecture and interior architecture. User control over the lighting system is important, by dimming or increasing light output, by changing the colour of the light sets the inner atmosphere and affects user mood. Standards and codes on lighting shall also be evaluated by means of these topics. The paper aims to analyse how the luminous environment is affective on the perceived environment. Hence, a series of experimental studies and recent research will be evaluated in regard to understanding and designing luminous environment.
