ENERGY CONSULTING SERVICES

Window selection, wall assembly, heating equipment, air conditioning, ventilation, lighting...these are just some of the various components that can impact a home or building's energy consumption. And these days it seems that there are just as many rating systems out there that use their own metrics to analyze and certify a project's energy efficiency.

​

Our team at ZON can help you navigate the waters of energy targets by identifying what matters to you, and establishing clear, specific energy performance targets for your project.  We work with architects, contractors and building owners directly to design and specify high performance building envelopes, efficient mechanical systems, and renewable energy sources.

NET-ZERO ENERGY CONSULTING

​

  • Detailed Energy Modeling - Using the architectural plans and elevations provided by the project team, ZON will review generate an energy model in industry-approved modeling software and provide recommendations to meet the Net-Zero objective by commenting on:

    • Enclosure thermal performance characteristics

    • Overall building air tightness targets

    • Thermal performance and solar heat gain coefficients for windows and doors

    • Overhang characteristics for summer shading

    • Window to Wall Ratios

    • Electrical lighting and associated control systems

    • Heating and cooling system options and efficiencies

    • Hot water heating system options

    • Hot water distribution system options (fixture flow rates, drain water heat recover, recirculation systems, etc.)

    • Ventilation system options, including pre-conditioning, heat recovery, and fan power

  • Design reviews of architectural, mechanical and electrical drawings and various design stage milestones

  • Energy Model updates as required

  • Air Tightness Testing

A Net-Zero Energy building is a building where the total amount of energy used by the building on an annual basis is roughly equal to the amount of renewable energy created on the site. The goal of any NZE building is to first minimize the amount of on-site energy consumed by addressing building components such as envelope, systems and occupant habits; from there, the remaining energy consumption can be offset with on-site renewable energy, such as a rooftop solar PV array.

​

Detailed energy modeling is a key component in establishing and achieving Net-Zero energy targets for energy projects. As leaders in the realm of energy conscious buildings, ZON provides energy modeling services and active design support to establish the required design targets and criteria for the overall building, the enclosure and the mechanical and electrical systems. Our Net-Zero consulting services include:

ENERGY AUDITING

Buildings consume a lot of energy on a day-to-day basis. In Canada, it is estimated that commercial buildings alone consume approximately 12% of the total energy use in the country, most of which is used by a building's lighting, heating, cooling and water heating. New construction building are required to meet stringent energy requirements that have been incorporated into building code and third-party certification standards, but what about existing buildings?

​

This is where ZON comes is. Whether you're looking to reduce your buildings annual operating costs, identify equipment deficiencies or operational improvements, or are looking to shrink your building's carbon footprint, the team at ZON can guide building owners and operators through the energy audit process, which consists of the following steps:

​

Lighting Design Consultation

Document Review

  • Prior to any site review, our team reviews the drawings, building condition assessment, and utility bills provided. This will allow us to familiarize ourselves with the building layout and systems before carrying out the site assessment.
     

Site Assessment

  • Site assessment and consultation with building operators and occupants to assess the current site operations

  • Identifying opportunities for load control, load reduction and/or retrofit opportunities (e.g. heating equipment, lighting, fans, pumps, etc.)​
     

Report

  • As part of ZON's energy audit reporting procedures, our team will develop a comprehensive energy audit report that includes the following:

    • The current physical characteristics of the facility, major existing energy consuming building services (e.g. lighting, heating, cooling)

    • A complete breakdown of current building energy usage, consumption and costs by end-use type as determined by a metered utility data analysis and lighting audit

    • An analysis of irregularities in energy use patterns, with suggestions as to their possible causes

    • Identification of special problems identified including possible revisions to usage and O&M procedures.

    • A list of recommendation energy reduction measures identifying their resulting net effect on energy consumption for each energy source, and electricity peak demand reduction.

    • Estimated total capital costs for the list of recommended measures including both material and installation cost.

    • A review of non-financial considerations, including the health, safety and comfort of the occupants and staff.

    • Identification of measures that were considered by not recommended to be implemented, along with the rationale for each excluded measure.
