LexisNexis

Office Fit-out

HH Angus was engaged to provide fitout services for LexisNexis’ commercial office renovation. The client is a global provider of information and technology solutions for legal and professional services customers.

A major focus of the project was the refresh of the base building lighting to brighten the space. HH Angus provided a new lighting design for three floors, along with a selection of luminaires. Photometric calculations were made to achieve the client’s desired lighting levels. Rezoning lighting circuits and low voltage lighting zones was also part of the lighting scope.

The project’s mechanical scope included mechanical heat pumps, fresh air supply and duct work.

AV integration

The challenges we met on this project included meeting an aggressive schedule, and carrying out ongoing coordination with the client’s audiovisual vendor for a major integration of the AV system.

LED efficiency

The work included demolition of all existing lighting and T-bar ceilings, which were replaced with new T-bar and new, recessed LED lights.

Thunder Bay Regional Health Sciences Centre

Cogeneration Plant

The Thunder Bay Regional Health Sciences Centre required a new outdoor enclosed cogeneration machine to be integrated into the existing mechanical and electrical hospital systems to displace utility electricity and boiler production.

As prime consultant, some of the challenges we overcame on this project included: meeting the delivery deadline under a very tight schedule once the project was approved to proceed; working under the confines of space constraints; noise suppression requirements associated with working in an operating healthcare facility; and integration and use of low temperature water from cogeneration.

To address these challenges, HH Angus pre-tendered the equipment, which allowed for unit production while mechanical and electrical design continued. To address the issue of noise infiltration to the hospital, the unit noise suppression was specified to very strict levels, and these were successfully met.

Although low temperature heat is normally unused in this process and is displaced to the atmosphere, our design incorporated low temperature heat along with high temperature waste heat for use in the dearator make-up. This feature adds a level of long-term efficiency to the installation.

Yukon Energy

Gas Drive Cogeneration Plant

Yukon Energy is a publicly-owned electrical utility that operates as a business at arm’s length from the Yukon government. It is the main generator and transmitter of electrical energy in Yukon and works with Yukon Development Corporation to provide Yukoners with electricity and related energy services.

There are almost 15,000 electricity consumers in the Yukon Territory. Yukon Energy directly serves about 1,700 of these customers, most of whom are in the communities of Dawson City, Mayo and Faro.

Included in our electrical scope for Yukon Energy’s new cogeneration plant:

Design of a two X 4.4 MWe Jenbacher 4160V LNG (liquid natural gas)-fed modular, containerized generation facility
Supply of affiliated electrical power equipment (interface power transformer & switchgear, including electrical protection and control) to integrate from the owner’s existing transformer T4 6900V secondary into the electrical generation system distribution to connect the generation equipment
Supply of station service transformer and distribution equipment to power all auxiliary equipment (jacket water pumps, dry cooler, battery chargers, module lighting, etc).

The Yukon Energy interface included a utility interface panel for complete utility interconnection to local standards. We provided interface wiring design for protection (ie. transfer trip) and SCADA, as well as outlining the electrical design for the switchgear container. Additional design included the balance of the plant engine electrical support services (HT & LT cooling, exhaust gas heat exchanger and fresh/waste oil and glycol makeup systems), etc. These services are supplied by a separate 600V service provided by the owner.

Temporal Power

Flywheel Energy Storage

“With thorough project management and smart engineering by the Angus team, they have been able to condense the schedule and, at the same time, lower our costs.”

— Geoff Osborne, Senior Associate, NRStor

HH Angus and Associates was engaged to provide the detailed electrical engineering and construction management of this flywheel energy storage project at Temporal Power’s Minto facility near Harriston, ON. Flywheel-based energy storage systems do not use fossil fuel and do not produce CO2 or other harmful emissions during operation.

Our electrical team provided consulting engineering to connect Temporal Power’s nominally 2MW of flywheel energy to (and from) the grid at distribution voltage, as well as commissioning of the site.

Grid frequency regulation is required by the IESO in the area northwest of Guelph because of fluctuating electrical load and generation; 2 MW of flywheel capacity can act as a sink or a source of electricity to stabilize frequency.

The vulnerability of the electrical grid and distribution service, as evidenced in the December 2013 ice storm that affected predominantly Ontario, Quebec and the Northeast US, is giving impetus to the move to smart grids, distributed power and storage systems. The Temporal Power facility serves to balance the system frequency, thereby reducing the need to have a more expensive and less responsive generating plant performing that function.

Each of the ten 250 KW flywheels in the plant weighs about 4000 kilos and spins at up to 11,000 RPM.The flywheels operate through five 480V inverters (ie, two flywheels per inverter, with one redundant unit). HH Angus designed and supplied the system that converts the local grid distribution voltage of 44,000V through 347/600V to 480V (and vice versa). In terms of interconnecting to the grid, this is very much like a generator project in that it does ‘generate’ 2MW when requested as frequency is decreasing. But it can also absorb energy when the grid frequency is ‘speeding up’.

Uber

Toronto Headquarters

In contrast to its forward looking and high tech business model, when Uber Canada was looking for office space in Toronto, they chose to set up shop in an old Post and Beam building in an historic area of the city.

HH Angus’ tenant group was engaged to provide mechanical and electrical consulting engineering to the 14,000 ft2 office fitout project.

As with many Post and Beam fitouts, one of the key challenges for the M&E systems designers was the client’s strong focus on maintaining the aesthetic of the building’s original character. This presents an engineering challenge when the interior design for the open concept collaboration spaces requires the major mechanical and electrical services to be exposed.

The solution to the aesthetics challenge was to have all equipment selections made to compliment the open concept and character of the building.
