dc.titleA study of lighting energy management opportunities in industrial buildings of Hong Kongen_US
dcterms.abstractThe lighting system provides many opportunities for cost-effective energy savings with little or no inconvenience. In many cases, lighting can be improved and operation costs can be reduced at the same time. Lighting improvements are excellent investment in most commercial business because lighting accounts for a large part of the energy bill - ranging from 30-70% of the total energy cost. Lighting energy in industrial facilities, but it is usually cost-effective to address because lighting improvements are often easier to make than many process upgrades. While there are significant cost-effective and power-demand reductions available from lighting retrofits and maintenance. A lighting retrofit program can be a win-win proposition for the business owner as it can improve morale, safety and productivity while reducing life-cycle costs. To demonstrate the potential for improved performance from corridor lighting through retrofit of electronic ballast and utilization of daylight controls for a sample floor of the industrial building were selected for a demonstration project. The retrofit project was carried out in two stages. The first stage was a straightforward to retrofit the original magnetic ballast with electronic ballast and cleaning of the internal reflecting surfaces and louvers of the luminaries. The retrofit work had been applied the CLP Power Hong Kong Ltd. rebate programmes for elimination of the initial cost. The second stage was installed a photocell feedback sensor near the windowed lift lobbies for collection the data in order to take advantage of the available daylight. The meter measured the energy consumption for the lighting circuit. Measurements of the lighting level were made before and after the retrofits. Two questionnaires were made and circulated to seek the opinion surveys. The questionnaire 1) was designed to investigate the opinion of the occupant towards the public areas lighting performance before and after retrofits. 60 sets questionnaire were distributed and 54 sets questionnaire successfully interviewed the occupant's opinion. In general occupants preferred the higher lighting levels resulting from retrofits. Questionnaire 2) was designed to investigate the opinion of management company towards on the maintenance practice of the public areas lighting. 24 sets successful questionnaire were surveyed with local management companies. Results showed that most of management companies have not any suitable maintenance programmes and cleaning schedule for lamp. Four Scenarios were made and outlined on the Excel spreadsheet for comparison of their life cycle costing. An economic maintenance scheme for public areas lighting was proposed to the building management company on the maintenance practice resulted from four different Scenarios. Power utility companies' rebate programmes have to help building owner on their initial cost of retrofit. Adoption of energy efficient electronic ballast was given a substantial saving on the energy cost. Industrial environments are an essential factor that influences the cleaning cost of the public areas lighting systems. Then, time and labour will be saved if the cleaning procedure is properly planned and the correct cleaning compounds for the various of a luminaire are used.en_US
