Energy direction is a subject which consists of a aggregation of thoughts and techniques associating to the extraction, distribution ; purchase and use of energy, the influence of the assorted professional cognition was developing by direction squad who set up a formal energy method and sketch the basic techniques which determine to travel the energy efficiency in edifice. Nowadays, many organisations would hold some move towards the more efficient usage of energy and utilize some renewable energy resources. It will assist cut down trust on fossil fuels and cut down green gas emanations. Energy direction includes effectual usage of energy to minimise costs and to heighten competitory concern state of affairs and involves energy consciousness and motivates employees and supervisors to salvage energy.
The climatic status provides an indispensable solar radiation to strike the solar cell to supply electricity energy. Hong Kong is a high rise and high denseness metropolis with a semitropical clime. Refer old chapter 2.3 shows the monthly norm informations of the general climatic status ; the information indicates that some months were important affect the planetary solar radiations from July to December, when deficient solar radiation must be consider to guarantee continues electricity supply by the subsidiary energy back uping. Furthermore, in Hong Kong weather status, solar cell system construction should be added excess installing cost to put the strong construction to defy high gales during typhoon season.
The economic sciences of PV system is determined by the cost of system and the production for the electricity generated. The cost of system includes capital cost such as investing, involvement and runing cost such as care, labour cost. Each proprietor need to understand the importance of each component and is necessary to happening the correct the economic balance of undertaking cost for solar energy application. Normally, a life-time of PV system 25 old ages is assumed. The accumulative operation cost are by and large low, the major economic factor required high initial investing that are high compared to fossil fuel and other conventional energy system, so economic analysis is highly of import for the applied scientist for measuring of energy engineerings. Beside, the solar cells have a high potency for dependability and long life.
Government ‘s function is of import for renewable energy deployment, energy policy scene will assist to develop energy markets and operate efficiency. Based on planetary environment impact in future, the authorities will go on to set up the schemes for energy sustainable development in public work undertakings and promote the private parties to take part. It can be help to reexamine authorities policy in order to place where the barrier can be removed. In Hong Kong, many complex ordinances of different authorities ‘s sections must be applied to put the PV system on the edifice or land by constructing developers or proprietors. For illustration, portion of electricity and mechanical must approved by EMSD and electric supplies company, portion of back uping construction design must approved by Building Department, and portion of H2O supply installation must be approved by Water supplies Department when is application of solar H2O thermal system. So authorities sections could be integrated to increase the development of renewable energy system.
The optimising energy attack adopted to utilize of assorted sort of operation activities that contains many-sided activities such as energy informations entry, categorization of energy cost and net income, supervising the public presentation of energy system and anticipation of equipment public presentation for remedial procedure etc. This would assist us in understanding the assorted parametric quantities on energy ingestion, energy efficiency, runing costs and maximise net income. The energy director enables to accomplish a better understanding the information of workss public presentation in their edifice and has led to works betterment and energy economy. This information is critical to implement the effectual energy direction plan.
Photovoltaic transition could be solved the proficient and economic jobs standing in the manner of widespread usage of solar cells. Large-scale application will necessitate much lower monetary value and installed in the countryside, they are already economically competitory, for illustration, China Light & A ; Power Company ( CLP ) is constructing the Hong Kong ‘s first standalone solar energy power system on Town Island in Sai Kung. Its system involved seting up 100 solar panels which can bring forth 20 Kilowatts. The following phase will put in up to 800 solar panels in 2011.
There is a metropolis of many high rise edifices and high denseness development in Hong Kong where is hard to advance the solar energy application and current edifice developers are deficiency of inducement in application of the renewable energy applications due to their concern grounds. Furthermore, Government ‘s has provided slenderly attempt for exciting the renewable energy market. Up to now, solar energy applications in Hong Kong are little in figure where about installed among in authorities edifices and public country. The undertakings included the central offices of the EMSD, Whachai Tower, Science Park and Castle Peak Hospital.
Harmonizing of phase study 1 by EMSD that evaluated the potency of different signifiers of renewable energy engineerings for local usage, PV systems are chiefly divided into 2 classs which are Building Integrated Photovoltaic ( BIPV ) type and non-BIPV type. The BIPV type is installed on rooftops, frontages and envelop of a edifice, while non-BIPV type is build along highway noise barriers, incline and non-building construction etc.
Solar energy in Hong Kong is regarded mildly rich, and has one-year mean planetary horizontal solar irradiance of 1290 KWh/m2. Harmonizing to the study indicated that the potency of solar energy in Hong Kong is 5944 GWh/year which is tantamount to around 15 % of the 2006 electricity ingestion [ 4 ] . This was derived by presuming that all executable land country of solar application were covered up by both BIPV and non-BIPV system. This could be rather a important usage of renewable energy to run into its energy demand. Although there is hard to happen suited location for big graduated table solar energy application in the high denseness urban countries, commercial edifices for put ining BIPV system are considered a sensible pick. The state side and new town are high potency for developing its energy system.
Government ‘s function provides really fiscal and proficient supporting, enforcement through statute law to excite to develop renewable energy market and pull all the people ‘s attending to understand the importance of energy salvaging through some sample presentation undertaking. It makes to increase public consciousness and instruction is important for the more development of renewable energy resources in Hong Kong.
In brief, people can larn about the importance of energy economy and how to effectual usage renewable energy that promote around the universe, more and more people understand to take better attention of the Earth. Business parties have chance for people who sell environmentally merchandises ; therefore clients have a opportunity to buy that enables them to populate without harming air and our working and life environment.
