Preface
This is the first edition of CSA EXP05, Methodology for evaluating energy savings from use of adaptive controls in street lighting applications. This Express Document is not a consensus publication; that is, it is not a Standard and it has not been formally reviewed or approved by a CSA Technical Committee.
Many municipalities and provincial utilities are engaged in the study of and the active replacement of street lighting luminaires with new, more energy-efficient light sources such as LED, while incorporating adaptive lighting controls to further reduce energy consumption. At the present time, most municipal staff do not have a background in engineering or in the electrical energy field, and thus have difficulty quantifying potential energy savings and seeing the benefits of implementing new technology such as adaptive lighting controls. Under the current practice, street lighting is not metered, and municipalities are billed based on assumed hours of darkness and for energy consumption by luminaire wattage. Any reduction benefits achieved through the use of adaptive lighting technologies result in energy reduction, but do not result in any reduction in billing.
CSA Group acknowledges that the development of this Standard was made possible, in part, by the financial support of BC Hydro, the Canadian Electricity Association, Hydro-Québec, Manitoba Hydro, Natural Resources Canada, and the Ontario Ministry of Energy.
Scope
1.1
This Express Document (herein referred to as this Document) describes a methodology for evaluating energy savings from the use of adaptive controls in street lighting applications and a means whereby municipal users of adaptive lighting controls on unmetered systems can be billed more accurately by their electric utility company.
1.2
This Document applies to all lighting sources that can effectively be controlled through dimming.
1.3
This Document contains no requirements. In this Document, should is used to express a recommendation or that which is advised.
