Net Zero Energy (or Net Zero Carbon) is an energy performance standard whereby a building has achieved net energy consumption of zero. In order to reach Net Zero, a building must either operate solely on renewable energy or, more commonly, produce on-site renewable energy roughly equal to the amount of energy consumed.

Energy Modeling is a powerful interactive tool that involves building a computer model of the building and its energy systems. This model is then used to provide an in-depth analysis towards more energy efficient buildings and to confirm energy code compliance.


The energy analysis covers all major energy systems within the building including the envelope, HVAC systems, lighting, and – should it exist – renewable energy.

Photovoltaic (PV) Solar systems are a source of renewable energy involving the conversion of light energy into electricity. MGB provides PV engineering assessment, design, and implementation services.


A PV assessment provides the potential annual energy production, payback for the system, and all costs associated with implementation and up-keep of a solar energy system. While design and implementation services follow a project from its concept design stage through to construction.

Passive House (Passivhaus) is an internationally acknowledged standard for energy efficient architecture. Buildings built to the Passive House standard consume roughly 80% less energy for heating and cooling than the conventional construction.


This standard is generally achieved through exceptionally high levels of insulation, well-insulated window frames and glazing, thermal bridge-free design and construction, an airtight building envelope, and highly efficient energy recovery ventilation systems.

Everyone wants to reduce their energy and water consumption, but it isn’t always obvious how to do it. An Energy Audit is a great way to understand the potential savings of an existing building.


The process begins with an analysis of the energy and water consumption associated with a single facility. The results are then compared to benchmarks of similar buildings in Canada or in a client’s portfolio of assets. Site inspections and meetings with the facility managers are organized to help gain a detailed understanding of the age, condition, and operational status of the building’s architectural, mechanical, and electrical systems. The final report details the status of the facility, provides tailored recommendations for energy conservation measures, and outlines potential energy savings, estimated costs of implementation, and a payback analysis.
