Micro-Management of Lighting Controls Projects
Abstract
A common lighting project is to evaluate a block of
rooms for savings and payback from the use of
photocells or occupancy sensors. The designer counts
the fixtures to be controlled, calculates the watts used
and then the expected savings. If the payback is not
agreeable to the owner, the entire project is
abandoned. This paper introduces a new computer-aided
approach that permits the designer greater
flexibility in the analysis of controls and promises a
higher level of savings for any given facility, thus a
shorter payback.
The computer program first prompts for the data on all
the rooms in a facility, including occupied hours at
present and actual hours per week the lights are
required. The routine then calculates the savings and
payback for every room and sorts them in descending
order of savings. The designer can target only those
zones with the highest potential savings so limited
funds can be put to best use. The program has a hall
range of data entry forms and reports that output the
data.
