Building Energy Services

WSP's energy services are focused on helping you reduce your operating costs and achieve the full potential from your building systems.


You need an experienced, knowledgeable team. Our Sustainability & Energy team is among the largest in the nation. Our group is diverse, with backgrounds in commissioning, mechanical design, controls and automation systems, construction, building science, and performance modeling. In addition, we are able to draw on the experience, knowledge and resources throughout WSP and WSP | Parsons Brinckerhoff in almost every area of building engineering, including one of the largest commissioning groups in the United States.

You will benefit from our wide-ranging and deep experience in existing building energy and systems performance. We have the tools, the know-how and the passion to deliver improved performance for your building.

We offer

  • Energy Management Planning

    Understand how your energy management processes and procedures affect building performance and gain valuable tips on how to improve building performance through best management practices.

    How your management team relates to resource consumption and communicates its priorities to staff and tenants has an impact on the effectiveness and persistence of your conservation efforts.

    We’ll interview your team to understand your current practices and processes, and we’ll evaluate your energy management practices. We’ll then make recommendations you and your team can use to help you become leaders in energy efficiency.

  • Integrated Energy Assessments (IEA), including Energy Audits

    Uncover greater opportunities for improving building performance and saving money through our integrated approach which combines the traditional Energy Audit with a Tenant Energy Assessment and elements of Retro-Commissioning.

    Energy Audits typically focus on equipment and retrofits. Using this process alone, important, cost-effective opportunities can be overlooked.

    WSP’s integrated approach considers all three of the most important aspects of building energy use: building systems, operations, and use.

    Building Systems
    This is the component that is typically covered in an Energy Audit. Here, we evaluate opportunities for improving your building’s systems and equipment and recommend appropriate upgrades.

    Building Operations
    By exploring how and when your systems operate, we go beyond a typical energy audit. Through elements of retro-commissioning, we are able to identify opportunities for operational improvements.

    Building Use
    The choices and decisions made by your management, staff and tenants impact your building’s energy performance. Through energy management planning, we uncover energy saving opportunities at the organizational level.

  • Retro-commissioning (ReCx)

    Save energy, improve comfort, and gain greater control over your building’s systems through Retro-Commissioning - a systematic “tune-up” that looks at the operation and performance of your building’s systems as a whole rather than the efficiency of individual pieces of equipment.

    Retro-commissioning (ReCx) is a systematic process applied to existing buildings to ensure continued efficiency over time. It is an overall tune-up for your building that looks beyond the efficiency of individual pieces of equipment to address system-wide functionality.

    While WSP’s ReCx work may include recommendations for capital improvements, the primary focus is on using diagnostic testing and tune-up activities to optimize building performance given the current needs of occupants and operators.

    The benefit of this activity is best illustrated by a recent Lawrence Berkeley National Labs study on the cost-effectiveness of commissioning. Of 643 buildings surveyed, over 10,000 problems were identified. On existing buildings specifically, correcting these problems lead to an average of 16% energy savings, with an average payback of 13 months.

  • Outside Air Analysis and Indoor Air Quality Assessments

    Increase occupant comfort and prevent excessive energy consumption by optimizing both the quantity and quality of your indoor air.

    Maintaining a minimum Indoor Air Quality (IAQ) performance in buildings improves occupant comfort, well-being and productivity. To achieve minimum IAQ performance, the building must allow for the circulation of adequate volumes of outside air.

    To determine minimum required flow rates for all occupied areas in the building, we perform ASHRAE 62.1 calculations. The amount of outside air actually being delivered to the occupied spaces by each air handler is then physically measured.

    Based on the measurements, and how they compare to the minimum required flow rates, we then provide recommendations to help you maintain adequate outside air to optimize occupant comfort and wellbeing while preventing excessive energy use.

  • Operator Energy Efficiency Training

    Train your operators to identify energy saving measures, and effectively troubleshoot energy efficiency problems.

    Our Commissioning experts use their deep knowledge of energy efficient building operations to deliver an operator training program that is customized to your building.

    Our Commissioning experts will also consult on energy saving strategies such as the application of variable speed drives and associated control sequences and strategies for optimizing and re-setting temperature and pressure set points to match building demand.

    As part of the training, we will:

    - Review the system as it currently operates
    - Lead the operations team through our investigation and analysis
    - Test the functionality of system equipment, then provide a tutorial on the diagnostic tests
    - Assist in developing a plan to implement the identified no- and low-cost energy conservation measures
    - Assist in developing a plan to incorporate this kind of commissioning and “energy efficiency troubleshooting” into your ongoing operations

  • Energy Incentives Consulting

    Reduce the cost of implementing energy efficiency improvements by relying on us to help you identify and apply for a host of energy incentive programs.

    Enbridge, Union Gas, OPA and BC Hydro are just a few of the many utilities and organizations across Canada that provide incentives to help reduce the cost of undertaking energy efficiency improvement projects.

    Through our relationships with these utilities and organizations, we stay up-to-date on the availability, requirements and deadlines for each program.

    We can provide you with advice and recommendations on the incentives that are applicable to your retrofit projects. We can also manage and complete incentive applications on your behalf.

  • Building Energy Simulation

    Let us help you predict how your building will perform.

    Many facility owners and managers are familiar with the use of energy modeling in the LEED certification process. But performance simulation can also be used to achieve other objectives.

    A building energy simulation, also known as energy modeling, is a systematic and holistic process. It lets you compare different design alternatives to help you choose the right performance strategy for your project. Where design information is not available for the model, we rely on industry-accepted typical values and previous project experience.

  • Energy Measurement & Verification

    Optimize your return on investment by ensuring your building is performing as predicted.

    Energy Measurement and Verification (M&V) closes the loop between the predicted and actual performance of building energy and water systems.

    Through the M&V process, we combine information about equipment performance gathered during the commissioning process with actual weather data and operational profiles used to calibrate the energy simulation developed for LEED Credit EAc1.

    Using metering equipment, we are able to compare the predicted energy use from the calibrated simulation to the metered data.

    The resulting data is a powerful tool to ensure long-term building energy efficiency and to demonstrate the success of your green initiatives.

    Benefits include:

    - better understanding of your building systems
    - ability to review the effectiveness of your facility’s green building strategies
    - opportunity to maximize efficiency by fine-tuning operational strategies
    - gaining of sharable real-time energy consumption data that can be integrated into capital planning and used to evaluate future retrofit opportunities

  • Commissioning

    Reduce energy costs, minimize contractor call-backs, and improve occupant comfort through commissioning.

    Commissioning (Cx) is a process used to ensure your building’s energy-consuming systems are designed and installed for optimum efficiency.

    Bridging the gap between building designers, contractors and operators, commissioning helps to integrate, verify, test and balance design, equipment, and systems, including control systems.

    Commissioning also results in better construction and system handover documentation and facility operations training.

  • Renewable Energy Analysis

    Explore the benefits, costs and return on investment of incorporating renewable energy initiatives into your new building project.

    WSP is able to provide a full range of services related to renewable energy systems. These include feasibility studies, design – of energy systems, structure and cladding – and construction review.

  • Carbon Assessments/Accounting

    Reduce your carbon footprint, qualify for the LEED Emissions Reduction credit, and prepare for sustainability reporting with a carbon assessment.

    WSP has extensive expertise in climate change and carbon management-related issues and greenhouse gas (GHG) accounting in particular.

    Our carbon analyses are CAN-ISO 14064, GHG Protocol and LEED Energy and Atmosphere Credit 6 (EAc6)-standard compliant.

    Our in-depth carbon accounting service does more than ensure your meet the requirements of the LEED EAc6. It also provides insight into your emissions profile and helps identify reduction opportunities through a comprehensive carbon management strategy.

  • Building Automation System (BAS) Consulting Services

    Focused on helping you understand the capabilities of your BAS and improving its operational efficiency.

    Take control of your ‘controls’. Maintain low operating costs through energy management strategies with the use of your building automation system (BAS).  Be pro-active in facilities management by monitoring the day-to-day operation of your equipment and environmental conditions. From BAS assessments to full BAS design services, you will benefit from our teams’ extensive experience.
