Daylighting Potential in Thailand

Daylighting has good potential for application in tropical climates. It can help save electric energy as well as reduce the daytime power demand substantially. It can bring another dimension of energy efficiency in addition to efficient lighting technology, as well as aesthetic value. Its integration with continuous-dimming electric lighting is found to be acceptable. However, fundamental research as well as daylighting application technology are required to realize the potential.

Efficient Energy Utilization and Lighting Technology.

The Illuminating Engineering Institute of Japan (IEIJ) organized the Special Technical Committee of Effective Energy Utilization in lighting in 1991, and made several surveys for almost two years. The aim of this committee was to have a better understanding of the present status of lighting technology in Japan especially from the view point of energy efficiency and thus to find the direction of lighting research. This report presents the summary of the energy situation and energy conservation policy of Japan, the present status of energy efficient lighting equipments, measures to reduce the electrical energy demand for lighting without hindering the quality and the present condition of effective utilization of energy for lighting in Japan.

Energy service company investments in energy-efficient lighting in Hungary

Severe shortages of capital impose severe restraints on the implementation of cost-effective efficient lighting technologies in Eastern Europe. The article examines whether third-party finance provided by energy-service companies can help improve energy efficiency in lighting by providing the necessary capital and technical expertise. Twenty third-party-financed projects for street lighting efficiency improvements have already been undertaken in Hungary. The capabilities of existing and potential lighting energy service companies are examined. The potential role of other actors in the development of third-party finance for lighting efficiency in Hungary is also discussed. Those actors include banks, the European Community, and Western energy service companies.

Ensuring market supply and penetration of efficient lighting technologies

Lighting is one of the major uses of electricity. State-of-the-art lighting systems can increase efficiency and reduce energy demand, but substantial market barriers hamper market penetration. In recognition of these market realities, electric utilities and government agencies in several IEA-member countries have begun to focus their efforts on demand-side oriented activities, such as light bulb give-aways, audits, education, standards promulgation, and other programmes. For example, in the U.S. the shipment of compact fluorescent lamps almost doubled between 1988 and 1990 and is forecast to increase by about 280% between 1991 and 1995. We project that annual utility spending on incentives for efficient lighting will grow to ~$300 to 800 million by 1994. These campaigns can also result in temporary supply short-ages, which can in turn impede successful implementation of the programmes. Efforts to address the problem must begin by enhancing cooperation and information exchange among utilities, manufacturers, and customers.

Energy-efficient lighting and lighting practices for the pulp and paper industry

The subject of energy efficient lighting and lighting practices for the pulp and paper industry offers an opportunity to discuss energy efficient lighting technologies, commencing with new current lighting products, the advantages and disadvantages of these new lighting products, coping with the disadvantages, their performance and design, and ways to apply these new products in an effective retrofit or in new construction applications. Current recommended lighting practices for indoor and outdoor techniques and economies with recommended illuminance values as applied to new projects or in the modernization of existing pulp and paper facilities are reviewed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
