Algonquin College Trigeneration Plant

HH Angus was retained to design a trigeneration plant for Ottawa’s Algonquin College. Our scope included review of Siemens’ PSUI application to IESO, and assisting with their application. Because the existing central utility plant (CUP) was not large enough to accommodate new plant systems, our team developed a pre-engineered building to be built adjacent to the existing CUP.

As Prime Consultant, HH Angus retained Milman and Associates to undertake the required structural engineering, including a roof design to accommodate the cooling towers, rad cooler and transformer. An additional mezzanine was added to house auxiliary equipment.

In order to maximize the usable heat during summer months, a 350 ton absorption chiller, using double effect flue gas and hot water, was detailed. The 2 MW reciprocating trigeneration plant features selective catalytic reduction units and a heat recovery boiler.

Some project challenges included:

Integrating and commissioning a trigeneration system into an operating facility
Noise constraints due to proximity of CUP to College operations
Space constraints due to pre-engineered building
Footprint was maxed out based on site restrictions; HH Angus had to take into account future co-gen, chiller and ancillaries
Ongoing upgrades in CUP heating and cooling, which HH Angus coordinated with another consultant
Operating flexibility required for both parallel and island operation
Solutions included: designed mezzanines in the existing CUP to house equipment and accommodate new, pre-engineered building for the second cogen and chiller; and rigorous scheduling coordination with Utility and College operations staff

Minimizing Disruption

All new equipment was connected to existing systems, with electrical connections restricted to well-planned shutdowns, resulting in minimal disruption to the ongoing operations of the campus.

Queen’s University

15 MW Cogeneration Facility

Acting as the Owner’s Engineer and Project Manager for Queen’s University, our involvement included: cogeneration plant design outline, equipment performance criteria, economic analysis review, the creation of project specific EPC&M contract documents, liquidated damages and insurance requirements, administration of contract documents, and life cycle analysis of tendered submissions.

The project-specific EPC&M contract included the Expression of Interest process, preparation of request for proposals (RFP) for engineering, as well as procure, construct and maintain contacts.

We also provided design review, schedule and cost management, scope control, contract administration, inspection services, commissioning assistance, and management and contract close out.

HH Angus was also retained for utility interface items, including design of the 44kV grounding transformer, transfer protection trip system and the natural gas letdown station.

Centre for International Governance Innovation (CIGI) Campus

“We asked for a design that sets us apart and fosters collaboration and intellectual creativity. We are very satisfied with the marvellous building that emerged.”

- Fred Kuntz, VP Public Affairs, CIGI

This new construction 100,000 ft2building is located within the CIGI campus in Waterloo, Ontario, and consists of tiered classrooms, offices and a two-storey auditorium. The Campus was honoured with the International Award for Architecture by The Royal Institution for British Architecture along with 12 other buildings globally.

HH Angus provided complete electrical, communication and vertical transportation consulting services for the new Balsillie School of International Affairs. This educational facility is in partnership with Wilfrid Laurier University, the University of Waterloo and the Centre for International Governance Innovation. It offers Masters and PhD programs.

Our Electrical scope included designing the building’s power distribution, fire alarm, emergency lighting, communications, audio visual and security systems.

A UPS system backs up the building server room to ensure critical research data was not lost during a utility power interruption. An emergency diesel generator was installed to support the essential loads throughout the building. Low voltage lighting controls and occupancy sensors were implemented as an energy savings measure.

The architect designed a large percentage of the ceiling spaces as exposed concrete. This presented an interesting challenge to our engineering design team, who delivered a solution incorporating all the electrical, audiovisual and communication services without affecting the architectural design intent.

BESS & Microgrid System

The battery energy storage system facility reduces electrical demand for a Class A electricity facility operating during anticipated Global Adjustment hours.

Johnson Controls, the turnkey EPC and facility energy service company, engaged HH Angus to engineer a 2 MWe (4 MWh) behind-the-meter battery energy storage system (BESS).

The installation is part of a microgrid design that incorporates rooftop solar panels for six buildings (~500kWe), a 2 MWe (4 MWh) BESS, and a 2 MWe natural gas engine-generator peaker. The goal of the installation is to reduce Global Adjustment charges. It also supports much of the facility in the event of a power failure on the grid.

The solar panels and BESS were installed during spring and summer of 2018, and the engine-generator peaker plant has been submitted for a building permit.

Ontario College of Art & Design University

Professional Gallery

The OCAD Gallery is the flagship professional gallery for the Ontario College of Art and Design, Canada’s largest and oldest educational institution for art and design. It serves as an experimental curatorial platform for art, design and new media.

HH Angus was tasked with the mechanical, electrical and lighting design for this 755 m2/8,200 ft2 facility. It includes gallery space, a media lounge, permanent art collection and storage, administration support services and shipping and receiving areas.

This project provided interesting design challenges to protect the art from potential water leakage from the tenants on the floor above. The ceiling is covered in a white waterproof membrane, which made recessed luminaires impractical.

The ceiling beams have a dual purpose – to support the track luminaires and to create an artistic industrial feel for the space. The track is two circuit to allow for maximum flexibility. LED track heads are 3500K with a CRI above 93 to enhance the colour of artwork in the exhibits. The track heads were chosen to allow for multiple and varied beams spreads, to enhance each exhibit and to provide flexibility by accommodating different lensing and media. Suspended linear LED luminaires were used in non-gallery spaces. Various power and data systems were used throughout the premises.

The heating and ventilation systems were designed to meet the mechanical requirements for a Class ‘A’ Art Gallery. The mechanical requirements for the Gallery consist of controlled humidification levels and temperature range. To achieve the requirements, a separate dedicated standalone mechanical air conditioning/humidification system was designed for the space. An indoor dry cooler and a series of heat pumps are located throughout the facility. Each heat pump has an associated electric humidifier and associated condensate pumps.

Meeting Project Goals

The OCAD project was delivered under budget and met LEED certification requirements.

Custom Lighting Requirements

A central dimmable lighting control system was incorporated. The lighting control was divided into multiple zones to satisfy the custom needs of the Gallery.
