Creative Energy

District Energy and Low Carbon Steam Plants

HH Angus is serving as mechanical and electrical engineers on Creative Energy's two new steam plant projects in downtown Vancouver.

For Creative Energy’s Beatty Plant, the existing gas plant is being replaced entirely by a new gas plant consisting of three 58MW and one 44MW industrial water tube boilers operating at 1.38 MPa (megapascal pressure). The boilers consist of the latest burner technology and FGR (flue gas recirculation), with guaranteed nitrogen oxide emissions of 8.5 parts per million. This plant is being built as part of Phase 1 of the new West Bank Beatty Street development. Careful phasing and design of the new plant on the existing site is required to maintain full operations of the existing plant until switchover can be completed so the plant can continue to serve its clientele of 200 buildings during the construction. 

HH Angus is also working with Creative Energy in the development of their new Low Carbon Steam Plant, serving as lead mechanical engineers and medium voltage and low voltage electrical engineers. 

The new steam plant is being developed in conjunction with the new West Bank Development at the intersection of Beatty St. and West Georgia and will feature electric boilers.  These electric boilers are being introduced by Creative Energy as part of their low carbon strategy.

Royal Inland Hospital

New Patient Care Tower

Royal Inland Hospital is a tertiary level acute care hospital serving a catchment area of approximately 220,000 residents in the city of Kamloops and throughout the Thompson, Cariboo and Shuswap regions of British Columbia.  

The 290,625 ft2 new Phil & Jennie Gaglardi Patient Care Tower (PCT) is a nine-storey building that includes a surgical floor, 13 operating suites, patient floors for mental health and medical/surgical beds, a neurosciences and trauma unit, perinatal centre, labour and delivery rooms, and neonatal intensive care unit. There are also two underground parking levels, administrative and clinical spaces on three lower floors, an intermediate mechanical floor, and 3 inpatient levels topped by a penthouse containing the heating, cooling, and emergency power plant.

Phase 2 consists of a number of renovations within the existing facility, including a completely renovated Emergency Department. Phase 1, which opened in July 2022, has achieved LEED Gold certification. HH Angus provided mechanical and electrical design services for the PCT, which was constructed adjacent to the existing hospital under a P3 contract.

Designed with direct input from local healthcare workers, the PCT streamlines access to hospital services through a single main entrance. A new post-anaesthetic recovery room in the adjacent existing facility’s renovated space will be constructed in Phase 2. Other clinical spaces include a substance use inpatient unit, a child and adolescent mental health crisis intervention program, maternal and child services, and respiratory therapy services. Non-clinical spaces include reception, patient registration, a rooftop helipad, underground parkade, retail space and a new home for the Royal Inland Hospital Foundation.

The mechanical design included energy-efficient heating and cooling systems with a variety of heat recovery features. The project had an ambitious energy use target and HVAC systems were designed with this benchmark in mind. Current estimates predict 24% savings in energy costs.

HH Angus was able to solve a problem the Hospital was having with the existing distributed hot water boilers by upsizing the new plant to serve the majority of the hospital campus. The ventilation design includes redundant capability and outbreak control, and exhaust air heat recovery, as well as providing for future flexibility.

The Health Authority expressed an interest in the ability to conduct smudging ceremonies in any patient room without having to make significant modifications to the current ventilation design and infrastructure included in the project.  HH Angus found a means for using the ventilation system as originally designed and applying a unique operational sequence to minimize capital cost changes while providing the ability to undertake smudging activities in any of the patient rooms on the Medical/Surgical and Mental Health Adaptive inpatient units.

A central focus of the design team was to work with the commissioning team to ensure proper operation of the new facility. The design team is now helping monitor ongoing operations to recover and reuse as much waste heat as possible. This effort concentrates on the heat recovery chiller plant operation to meet as much of the building’s heating load as possible using waste heat. This contributes to minimizing the production of GHGs from heating energy sources and, in turn, improves decarbonization for the new facility. New electrical services include a 25 KV service from BC Hydro serving a new outdoor substation powering the existing campus and PCT. New redundant 25kV to 600V FR3 transformers feeding the new tower were provided in the new main electrical room. Three new 2MVA diesel generators provide emergency power backup to the new patient care tower and the rest of the existing campus if utility power is lost. 600V distribution on both utility and generator power are provided with high resistance grounding to increase resiliency and reliability in the event of a single ground fault. Numerous low voltage systems were provided including fire alarm, lighting control system complete with daylight harvesting, circadian rhythm tunable lighting in the Neo-natal ICU, and electrical metering.

Helipad Design

The rooftop helipad is served by a number of mechanical and electrical systems to help keep the pad surface clear of snow and ice and to provide appropriate safety lighting to meet all requirements. Fire protection and life safety systems, such as foam suppression, were carefully coordinated and designed to ensure full coverage and containment in the event of a discharge.

Systems Integration

 Integration with the existing hospital systems was a significant challenge and required numerous connections to the adjacent facility. Requiring multiple site visits, it was determined the two facilities could be successfully integrated by enclosing an outdoor courtyard between them, transforming it into a four-season space that will benefit patients, staff and visitors. On the electrical side, backfeeding the existing facility with new 600V HRG generator backup required careful analysis of existing distribution to ensure compatibility for all existing equipment to the new 3 wire distribution on emergency power. A detailed sequence of operations for black start sequence and retransfer of automatic transfer switches to normal was developed and commissioned to ensure proper operation for different failure scenarios.

Hudson Pacific Properties

Burrard Exchange

Burrard Exchange adds to HH Angus’ growing portfolio of commercial, healthcare and mission critical work in Vancouver and the broader BC region.

In September 2021, Hudson Pacific Properties, in partnership with Blackstone Real Estate, unveiled plans for the addition of a hybrid mass timber 16-storey office and retail development to downtown Vancouver’s Bentall Centre, adding 450,000 ft2 of office and retail space within the complex.

Once approved, the new building, called Burrard Exchange, will be one of North America’s tallest exposed mass timber office buildings. The mass timber construction technique will support the project’s sustainability goals and reduce embodied carbon.

HH Angus is providing mechanical and electrical engineering, IT/communications, and energy modeling consulting services for this exciting new commercial project. Kohn Pedersen Fox Associates is the design architect and Adamson Associates Architects is the architect of record.

"Our team is excited to be part of this project for a number of reasons." said Kevin O’Neill, Commercial Division Director at HH Angus: "That the project will set a new benchmark for green construction in Vancouver and the innovative use of mass timber are key highlights for us. We’re thrilled to be working with Hudson Pacific Properties, KPF and Adamson Associates on this development."

HH Angus provided consulting engineering services to another timber project completed in 2020 – Oakville Fire Station 8 – which used cross-laminated timber in its construction.  One of the special considerations of using timber is that it requires both expertise and unusually close coordination between the M&E designers and the structural designers since, unlike drywall, wood openings cannot be adjusted once cut.

AstraZeneca 

Tenant Fitout

“The goal of AstraZeneca’s iWORK workplace strategy is to create facilities that meet expectations of how a great place to work should look and feel.”

AZ Workplace Strategy Guidelines

A further goal of the fitout was to use available space more efficiently to create more collaborative, vibrant working environments to achieve a science-driven, patient-focused culture and mindset.

HH Angus provided M&E consulting engineering and IMIT communications design to the project, which presented a number of interesting challenges requiring thoughtful solutions. Among the challenges was an aggressive schedule. The team worked efficiently and collaboratively to meet the project deadlines.

The project did not allow for core drilling to feed workstations or standalone furniture. To address this, the design team and engineers had to be strategic in using perimeter and under-carpet raceways to conceal wiring. A new lighting design was implemented throughout the 5th floor, and provided a sophisticated wireless lighting control system, complete with daylight harvesting and an occupancy setting, independent of the base building control system.

During the schematic design phase, our team noted several deficiencies within the existing base building system affecting the project’s location. We requested the team have a complete site audit done by a local air balancing contractor, which identified several issues with duct connections, system operation and controls. Through this process, we were able to rectify many issues prior to the close-out phase of our project. This resulted in an efficient transition for the client, saving them both time and money.

Open concept design

The client had expressed a preference for an open floor layout; however, several of the base building risers were in locations not conducive to the planned interior design. In order to accommodate the client’s wishes, we proactively identified a new shaft location, and re-routed various systems to deliver the floor layout desired by the client.

Pandemic response

The COVID 19 pandemic began in the midst of construction. The project team reacted immediately during these challenging times by providing effective and responsive coordination virtually. The team worked through construction-related delays, and helped mitigate supply distribution delays by using local contacts to expedite shipping to meet the client-requested deadlines.

The McEwan Group

Fabbrica TD

Fabbrica's second location was designed as a take-out venue. The 4200 ft2 retail space is accessed via Toronto's underground PATH system, in the heart of the city's financial district. Fabbrica on the PATH joins its sister outlet across the hall, the McEwan grocery store.

HH Angus was engaged to provide mechanical, electrical and lighting design services for the tenant fitout of the new Fabbrica on the concourse level of the TD Centre. Fabbrica took over an existing space which required ceiling demolition in order to install new lighting and electrical systems.

Custom interior lighting was designed to attract the attention of commuters and shoppers in the PATH system. To achieve this, 3500K 12W high-colour-rendering LEDs were incorporated into the lighting design to showcase the vibrant colours of the meal offerings prepared for hungry consumers.

The project's location in the concourse level posed a design challenge to the team, due to the modest amount of ceiling and underfloor clearance. To accommodate these restrictions, HH Angus designed solutions to manage the routing of piping, conduits and drainage within the limited space.
