Brantford Power
Landfill & WWTP Cogeneration 5.4 MW
HH Angus was retained to provide a turnkey natural gas fired cogeneration plant to take in landfill gas and digester gas and, in turn, produce electricity to feed to the Ontario power grid.
The cogen plant also transfers heat back to the digesters for process treatment of municipal liquid waste. In a future phase of the project, heat would be distributed to a district energy system.
Brantford is unique in that its solid waste landfill and the municipal wastewater treatment plant (WWTP) are adjacent to each other. Based on the available methane from the WWTP and the landfill, two 2.7MWe engines were provided (5.4MWe total), with a provision for an additional set as the landfill continues to grow.
The engine hot water is 95˚C and designed to be distributed to the adjacent WWTP. The design allowed for future exhaust gas recovery when the planned district energy system was developed.
The electrical output is 42% of the energy input, and the overall efficiency of the system was designed to be 88%, assuming that full thermal recovery would be implemented in a future district energy phase.
The station service load is supplied by the utility at 347/600V; however, the power is generated at 4160V and steps up to 27.6kV to supply into the grid. Synchronization is at 4160V.

York Region
Operations & Maintenance Bus Garage
The 230,000 ft2 Bus Garage in Vaughan, Ontario was retrofitted to accommodate the storage and maintenance of 230 York Region Transit (YRT) buses.
The facility was improved through a wide range of bus servicing equipment and building automation systems to minimize energy use and maximize operational efficiency. Both a new admin area and a training facility were included in the retrofit, which has been certified LEED® Silver.
The facility features state-of-the art ventilation and exhaust systems. There are two service lanes consisting of four indoor fuel pumps, vacuum stations, welding and body shop, paint booth, parts storage, tire bay, machine shop, two inspection pits, lubrication stations and two washers.
Our electrical scope included: normal and emergency power distribution design, fire alarm system design, telephone/data, communication conduit/raceway design, security system conduit/raceway design, system clock design, indoor lighting, and outdoor lighting design to meet LEED® Silver requirements.

KEY SCOPE ELEMENTS
Building automation and bus servicing equipment to improve operational efficiency | Normal and emergency power distribution | Energy-efficient system design to reduce water and energy demand | LEED Silver Certified
Energy efficient systems design
The building was designed to reduce energy and water demand. It includes a solar hot water system, and collection and storage of rainwater for washing buses and flushing toilets. The high efficiency HVAC system employs air-to-air heat exchange and is governed by a Building Automation System.
Best practices for environmental gains
Specifying for the light coloured roof helps reduce cooling demand in summer and mitigates the heat island effect. Interior materials and finishes were selected for the best possible indoor air quality. The construction waste diversion target was 95%. Best practices commissioning was used to ensure the building operates at optimal efficiency.
Simcoe-Muskoka Regional Cancer Centre
The Cancer Centre offers area residents a full service cancer centre “close to home”. The outpatient building was built as a 75,000 ft2 separate wing of the Royal Victoria Regional Health Centre in Barrie. Connected to the Hospital, it was designed to enable future expansion with relative ease.
HH Angus designed the new Cancer Centre, which included four Radiation Treatment Rooms (with possible expansion of four additional rooms), Patient Chemotherapy area, CT/Simulator, and all typical associated facilities. Chilled water and hot water are produced in the Cancer Centre; normal power and emergency power are obtained from the Hospital.
The Cancer Centre is three storeys, with each level planned around the patient. Level One houses Radiation Therapy, Level Two includes supportive care and outpatient clinics, and Level Three accommodates the chemotherapy and clinical trials programs.

University of Waterloo
Humanities Chiller Plant
HH Angus provided prime consulting engineering services for mechanical, electrical and structural design, project management, and construction administration services for this new Chiller Plant at the University of Waterloo.
The installation included two new 1000 ton, low-pressure centrifugal chillers, two new 1000 ton induced draft cooling towers, associated ancillary equipment, an emergency refrigeration ventilation system, and a chiller plant control system.
The electrical design featured new electrical infrastructure to accommodate the addition of new switch gear, transformers and electrical distribution to all ancillaries.
We used Bentleys Autoplant 3D software for the mechanical piping and ventilation design to ensure the functionality of the equipment and piping layout design. We also provided our client with documentation for pre-tendering of chillers and assisted in evaluation of the tenders.
As Prime Consultant, we engaged a structural engineer to design the necessary infrastructure on the roof to support the new cooling towers.

The Town of Jasper
Jasper Activity & Aquatic Centre
A key part of the heart of the community, the Jasper Activity and Aquatic Centre is used extensively year round. Originally just an outdoor pool with a small stone change room built in the 1920s, it has been transformed into a major facility with ice rinks, curling rinks, meeting rooms, daycare and a senior centre.
HH Angus was responsible for the engineering and design for approximately 25,000 ft2 of renovations to the main entrance lobby, daycare, administration offices, as well as a new 5,000 ft2 open concept space for the fitness centre relocation.
Sustainability, health, wellness and community were key goals, supported by use of natural materials, daylighting and special features such as a green roof, photovoltaic cells and storm water collection and reuse.
