Retrofit your building to reduce its energy use

The first step is to gather data on how your building is doing through an audit. This means examining your building’s roofs, windows, lighting, water, elevators and building control systems to identify any issues and establish a baseline for the building’s performance.

Doing an energy audit is a great way to start seeing where you can make the greatest improvements in energy efficiency. The ENERGY STAR^® Portfolio Manager is a free web-based tool you can use to compare your buildings to other commercial buildings in North America.

You can also find an energy consultant to help you. There are many engineering and sustainability firms that can help you through the whole process: assessing your building, suggesting solutions, designing technical plans for the project, and even helping you find the necessary contractor(s). For large projects, you might hire several consultants for different areas.

These are the elements you should have in your plan after you have assessed your building:

1. Set objectives for energy efficiency

Canada has many green building certifications, including LEED, R-2000, Novoclimat, EnerGuide, BOMA Best and others.

2. Assemble your team

Who needs to be involved? This may include building management, your current service contractors, your employees, etc.

3. Review your essential services

Check maintenance logs for your building for systems such as air ducts, smoke detectors and fire dampers and incorporate them in your retrofit if necessary.

7 simple ways to improve energy efficiency in your building

Article | 3-minute read

A good rule of thumb is to keep it simple. The most basic technologies to install are a building control system and a sub-metering system to measure utilities. You want your building to be easy to manage and maintain, and if you install an automated system, make sure it is easy to override manually. Here are the steps to selecting the right technology for you:

1. Create initial designs

This is when you draft the concept and design schematics for the retrofit. Sometimes called a Basis of Design (BOD), this lays out the upgrades, modifications and replacements for the building and its equipment.

2. Review the cost implications

Make sure that the return investment of these designs make sense and that they meet your objectives.

3. Draft technical specifications and an implementation plan

Once approved, you’ll need the technical drawings and models to start implementation of the project.

Now you’re ready to find the plumbers, electricians, air conditioning experts or general contractors to carry out the project.

Some questions to ask while you’re making the selection:

• What experience do you have with similar projects?
• Have you worked within similar budgets and schedules before?
• Can you provide referrals?
• Will you also update the systems documentation so we can refer to it in the future?
