A1 INTRODUCTION (incl. Energy Savings)

This is a practical guide, designed to provide information on lighting technology that will help to improve energy efficiency opportunities through a designed approach by understanding components and technologies that are commercially available. It is strongly recommended that individuals or companies undertaking comprehensive energy efficiency projects secure the services of a professional energy efficiency specialist qualified in lighting design, to maximize the benefits and return of investment by considering the internal rate of return and related benefits of a ‘quality’ design.

This Guide is aimed at new construction and renovation projects alike. It outlines new technologies, methods and systems to make lighting more efficient in your business or home. As considerable time can pass between major renovations, not implementing a lighting efficiency upgrade can represent a lost opportunity.

What this Guide Is and Is Not

  • This Guide was written to help you become aware of issues and technologies associated with lighting.
  • This Guide addresses the components and technologies that are commercially available and associated with construction techniques in the province of Ontario.
  • This Guide does not address the behavioral usage of lighting.
  • This Guide is intended to help the reader think about the fundamentals of energy use associated with lighting, for both new and renovated properties.
  • This Guide is general in nature and does not address each and every possible problem and solution that is associated with lighting technologies and their implementation.
  • This Guide is not a design guide or manual and is not intended t replace equipment manuals, design standards, maintenance procedures or applicable building codes or lighting standard.

Increasing energy costs have become a significant concern and are expected to continue to increase in the foreseeable future. Businesses, institutions and consumers will be searching for more efficient products and solutions. Business applications for more efficient products are available and even greater opportunities exist in the largely untapped residential market. Lighting is recognized as a major area for economic energy savings.

Programs are in place to influence market and consumer choices towards more energy efficient products. For example, “High Performance New Construction (HPNC)” and the "Electricity Retrofit Incentive Program (ERIP)" along with the use of the Energy Star labelling program are some of the programs to promote energy efficient lighting products.

There are also national efforts to mandate and in some cases regulate energy efficiency and appear in various forms such as codes and standards and building guidelines to limit energy use within a building such as ASHRAE-IES 90.1 Standard for Buildings and Minimum Energy Performance Standard regulations through the Federal Energy Efficiency Act.

Achieving lighting energy savings is considered one of the fundamental energy efficiency measures; opportunities include:

  • Replacing incandescent with fluorescent or HID lamp types.
  • Redesigning older fluorescent lamp configurations to meet present applications, such as in industrial plants with upgraded fixtures or better technology.

Lighting projects, executed properly and comprehensively can be easily justified for a number of reasons including:

  • Energy savings, often a 25% internal rate of return or better;
  • Emission reductions, direct correlation between energy and emission reduction;
  • Maintenance cost savings from replacing inefficient systems;
  • Increasing light levels for tenant comfort or improved safety considerations;
  • Improved colour rendtion to enhance comfort.
