Assessment of the overall evaluation of the load
Consider items that comprise the total cooling load can cause the peak load, which can be reduced to localized treatment, such as shading, changing the lighting, the export of machinery and other Detailed analysis of this kind can lead to substantial savings in plant size and future operating costs.
A thorough site survey should be carried out, if the building is erected, to verify data and search pressures, which may not be apparent from the available information. It will be shown that the total cooling load at any moment, consists of a large number of items, some of which may be known with certainty, but many of which are temporary and can only be assessed in reasonable proximity. Even the most complicated and laborious calculations, will contain a number of approximations, short cuts and empirical methods are very much in use. Abbreviated tables are given Gosling (1980) and Jones (2000). Full physical data will be found in the CIBSE guide books.
Since the evaluation will be based on the desired indoor conditions at any time, it may not be easy to see how the plant size can be reduced through some temporary relaxation of a specific standard. Some of the programs available that can be used to indicate the potential savings in capital costs and energy use in such conditions...
