Preface

This is the fourth edition of CSA Z317.5, Illumination design in health care facilities . It supersedes the previous editions published in 2017, 1998, and 1989. It is one of a series of Standards that establishes criteria for the development of a health-promoting environment in health care facilities (HCFs). The following are the major changes to this edition

1. updates to reflect modern lighting technologies and practices in health care facilities
2. revisions and additions to harmonize this Standard with CSA Z8000
3. new clause on sealed luminaires
4. updates to Clause 5 to align with common healthcare applications and the subdivision of Class A and B requirements to better clarify the differences between HCF types
5. the addition of new clauses to address long-term care facility design, including lighting for resident rooms, corridors, and common areas, with geriatric-specific guidance and accessibility provisions
6. updates to energy efficiency requirements, including minimum luminaire efficiency, use of occupancy/vacancy controls and daylight integrations and dimming controls
7. updates to minimum maintained illumination levels in Tables 1 and 2
8. and addition of new annexes on sealed luminaries (Annex E), integrative lighting design (Annex H), and expanded colour quality guidance (Annex F); CSA Group acknowledges that the development of this Standard was made possible, in part, by the financial support of the governments of Alberta, British Columbia, Manitoba, New Brunswick, Newfoundland and Labrador, Northwest Territories, Nova Scotia, Nunavut, Ontario, Prince Edward Island, Québec, Saskatchewan, and Yukon, as administered by Canada's Drug Agency (CDA-AMC).

This Standard was prepared by the Subcommittee on Illumination in Health Care Facilities, under the jurisdiction of the Technical Committee on Health Care Facilities and the Strategic Steering Committee on Health Care Technology, and has been formally approved by the Technical Committee. This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group

Scope

1.1 Design criteria

This Standard provides specific design criteria for illumination in various locations within a health care facility. Note: Lighting is both an art and a science. The basic technical criteria given in this Standard are not intended to inhibit creative design, but rather to ensure that minimum requirements are met.

1.2 Areas of focus

This Standard deals with

1. illumination sources
2. luminaires
3. illumination levels (see Tables 1 and 2)
4. and guidelines for specific areas and tasks

1.3 Exclusions

This Standard does not deal with

1. therapeutic illumination devices (e.g., phototherapy lamps)
2. and special-purpose devices such as UV sources for sterilization

1.4 Requirements

This Standard addresses requirements for illumination design. However, it is not meant to remove the need for consultation with users regarding specific or unusual requirements.

1.5 Regulatory authorities

The requirements in this Standard are intended to be subordinate to applicable provincial, federal, or local authority having jurisdiction (AHJ).

1.6 Terminology

In this Standard, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the Standard; "should" is used to express a recommendation or that which is advised but not required; and "may" is used to express an option or that which is permissible within the limits of the Standard. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
