Driving Business Results Through Better Engineering

Our Services 

Many of the mechanical elements of buildings that impact occupant comfort, such as cooling, heating and ventilation, are hidden behind walls or in specialized rooms. When well designed, they are essential to a high performing building where people can work, play or live. We care deeply about designing spaces that are healthy, comfortable, safe and productive for people and communities.

Digital Strategy & Planning
Exploring possibilities

Digital technologies are impacting how organizations design, build and operate buildings. As technology rapidly evolves, and the choice of systems, software and devices proliferates exponentially, it’s important to have an trusted advisor who can clarify opportunities, benefits and risks.

Our consultants and engineers provide business case analysis and early stage consulting services to help clients better understand and explore the options available to them. We leverage our expertise in the built environment and our understanding of technology and business consulting to identify what is possible. 


Smart Buildings
Minimizing operating costs

The goal of a Smart Building should be to connect building systems and operations in ways that minimize operating costs and improve the building’s ability to conserve energy and water, while enhancing the employee experience and effective use of space. We work with building owners, developers, architects and engineers to understand the business goals for a smart building or space, employing a consulting framework to define requirements in order to design modern and intelligent building technology solutions.

A responsive and optimized integrated environment draws from data-rich, connected systems to provide actionable insights that enhance the human experience and support the efficient operation of your facility. A Smart Building will leverage the Internet of Things to connect building automation systems, capture data on occupant behavior, and interpret this data to identify and surface trends.

Optimizing Performance

Our approach to commissioning emphasizes technical review and analysis of the design to develop project-specific procedures that provide a repeatable testing methodology. These procedures go beyond simple verification “checklists” and include specific instructions on how to conduct the performance and controls validation tests. Our objective is to help you optimize the performance of your building, recognizing that areas such as energy efficiency, sustainability, occupant comfort and safety, security and productivity all impact achieving optimal performance.

All of our commissioning personnel have spent many years in the industry, both in consulting engineering and in the construction trades. This combination allows us to approach every project with a fundamental understanding of site issues and to call on personal experience for effective and prompt project resolution. 

HH Angus is a founding member of the Building Commissioning Association (BCA), Eastern Canada Chapter. The BCA provides leadership in the building commissioning industry by collaborating with commissioning practitioners and other stakeholders. It upholds the highest standards and practices for the commissioning process by promoting the certification programs and trainings.

P3/Design Build/IPD

Powerful partnerships

Public and infrastructure projects increasingly are turning to project delivery methods such as Design-Build, Public-Private Partnerships (P3s) and Integrated Project Delivery (IPD) to better manage project costs and risk. While these methods of project delivery vary in approach and structure, their common element is tighter integration between architects, engineers and builders, which increases collaboration and controls cost. HH Angus has decades of experience in each of these project delivery methods. 

Our P3 experience spans both Proponent and PDC (Planning, Design and Compliance) work. We were the lead mechanical and electrical engineers for the largest P3 healthcare project in North America – the $2+ billion CHUM hospital in Montreal. Other HH Angus P3 projects include Royal Inland Hospital in Kamloops BC, the $5.3 billion Eglinton Crosstown LRT in Toronto, and the Downtown Relief Line subway in Toronto.

With its broad experience, HH Angus’ VT group is equipped to handle the most complex design challenges, both internationally and domestically, providing a wide range of client sectors with unified, complete and appropriate design solutions. 

We provide solutions for new construction as well as for existing buildings where we assist with equipment assessments and maintenance requirements, and advise on improvement and modernization.

Energy Modeling & Simulation
Utilizing technology

Energy simulation is a key tool for facility design, life cycle costing and ongoing performance of a building over its lifetime. We understand these elements go hand-in-hand and that’s why we place a strong emphasis on energy modeling. Our dedicated, in-house team performs energy simulation and analysis of buildings for which we design systems. 

We have developed custom programming to deal with unique mechanical systems for situations when the project cannot be modeled easily in standard simulation software. The software we use includes EnergyPlus, IES Virtual Environment and eQuest, as well as customized Revit APIs which facilitate integration with BIM to improve coordination and collaboration among the project team.

As computational power has increased, we have become adept at leveraging generative modeling strategies to benefit our clients, particularly in the early stages of design, to evaluate a multitude of options and approaches. Generative modeling consists of evaluating options for every relevant variable and simulating all possible resulting combinations – allowing stakeholders to evaluate their design options more easily.

Greater collaboration

BIM, coupled with powerful design and simulation tools, is fostering greater collaboration between the disciplines of architecture, engineering, and construction, which benefits how project teams work today. We were early adopters of BIM and are using database-structured BIM software, such as Revit® MEP, as our primary design tool. HH Angus has the ability to work in the latest version of Revit, and is well-versed in the BIM standards and protocols outlined in the AIA Standards. We carry 100+ licences for mechanical and electrical staff who are highly trained to design and model building systems in Revit, including HVAC, plumbing, electrical distribution and lighting.

We are also well versed in the Autodesk suite of design products, in addition to other relevant third party database and analysis software. For any project, our goal is to identify and deliver on the particular BIM

needs of the client’s facility. This often involves finding innovative ways to use Revit, using other BIM-driven software, 3D scanning techniques or 360 cameras, or creating a customized approach to analyzing, processing and managing data through the Revit API and Dynamo. We have the flexibility to meet your needs at every phase of your project’s lifecycle, including facilities management.

Reality Capture (3D Image Scanning & Modeling)

Accurate as built

Capturing data of existing buildings to create 3D as-built models is known as ‘reality capture’, and confers significant advantages over traditional approaches. 3D scanning technology continues to improve in speed, accuracy and ease of use, and provides a seamless transition between the real world and the digital. Building owners, developers, facilities managers, architects, engineers and contractors are now able to incorporate accurate as-built 3D models into planning, design, construction and ongoing facilities management.
