THE STRUCTURECRAFT BUILDING Mass timber industrial building adds to BC’s portfolio of green buildings Industrial buildings have for many years been a bulwark of standard, large-scale steel and concrete construction. The use of a green material, such as wood, has generally been considered inappropriate due to prohibitive cost, misperceptions around fire performance, and a generally unfavourable comparison of wood’s strength to the well-known load bearing capacity of steel. However, as in the commercial and residential sectors of North America, new winds are blowing in the industrial sector.

Vancouver, and its surrounding suburbs, has become a central hub of advancement in commercial and residential green buildings, and it also now showcases a new type of timber building – a 50,000 square foot, pre-fabricated industrial facility and office in Abbotsford.

FALL 2017 | BC FOCUS

The fabricator, engineer, and installer of this building, a mass timber design-build firm based near Vancouver, has been pushed by the recent boom in demand for mass timber buildings to expand into its own industrial shop and engineering office. One impetus behind developing the new StructureCraft facility was the creation of a prototype for prefabricated, efficiently designed, wooden industrial buildings.

With this in mind, special consideration was given in the design phase to a building which would not only meet and exceed all fire, seismic, and safety codes, but would also push boundaries in construction speed and cost.

The superstructure of the 40,000 sqft manufacturing facility was erected and roofed in just five days, using prefabricated wall and roof panels. (Time Lapse: https:// vimeo.com/221934678). Each panel was carefully modelled and engineered, assembled in StructureCraft’s old shop in Delta, and shipped to the new site in Abbotsford.

The 12’x60’ roof panels and 12’x34’ tall wall panels represent a prefabricated timber counterpoint to the tilt-up construction prevalent in concrete industrial buildings.

The 10-tonne crane system throughout the building is fully supported off the wood structure, only using steel for the crane rails themselves.

A 10,000 square foot office wraps around the front of the industrial building, and is constructed almost entirely of mass timber panels supported on a glulam frame of columns and beams. The desire to expose most of the walls and ceilings in the new office space required intense collaboration between the 3D modelling and engineering departments and the carpenters fabricating and installing the components.

The mass timber floor and roof panels throughout use a unique acoustic profile to create a high performing soffit with a Noise Reduction Coefficient of 0.7-0,8.

This is achieved as each of the boards in the panels has been profiled to allow a dense wood fibre to be inserted between the boards, creating a soffit with apertures which absorb sound waves. The office interior presents a clean, warm, and inviting aesthetic which looks forward to the future of mass timber office design.

The office was built utilizing mass timber not only to provide StructureCraft’s employees with a state-of-the-art workspace, but also to showcase the aesthetic of the new dowel-laminated timber (DLT) mass timber product which will be produced out of the main shop. The automated DLT press and manufacturing line is the largest and fastest in the world, and is intended to launch a new cost-effective mass timber product into the North American market.

GOOD NEIGHBOURS:

Using LEED and the CaGBC Zero Carbon Building Standard to augment the BC Energy Step Code In April 2017, the BC Government formally put its new Energy Step Code into force and the industry took notice. The Step Code defines increasingly stringent levels of energy performance, bridging the gap between the current BC Building Code and the net zero energy-ready buildings that the code is expected to demand by 2032.

The Canada Green Building Council® (CaGBC) supports the BC Step Code as an important signal to the industry as to the future evolution of the building code, which will facilitate adaptation and compliance. The Step Code also accelerates market transformation by providing a consistent set of stretch requirements that municipalities can readily embed into policies and programs.

The CaGBC appreciates the Code’s emphasis on building envelopes and ventilation strategies through the use of thermal energy demand intensity targets, and agrees that it’s critical for the Canadian design community to place greater focus on these aspects of building design in order to reliably achieve dramatic reductions in energy use.

Beyond Energy Energy efficiency is a key component of efforts to reduce emissions from building operations. The Step Code’s focus on energy efficiency aligns well with LEED, which weighs energy efficiency more heavily than any other component within the rating system. While energy efficiency is of vital importance, the CaGBC encourages the BC design community to think bigger. By applying LEED® or the CaGBC Zero Carbon Building Standard, projects can enjoy benefits beyond energy efficiency.

The Step Code uses the energy efficiency of basic building operations as a surrogate for GHG emissions. LEED enhances this effort by encouraging additional GHG reductions through measures that include renewable energy generation; participation in demand response programs; lowering the embedded carbon of construction materials; providing greater walkability and access to public transit; and promoting alternative fuel vehicles.

Additionally, with its broader holistic assessment of sustainability, LEED allows other important environmental impacts to be considered, including water efficiency, the sustainability of a site, construction waste, and the environmental impacts of materials. Equally important, LEED also places an emphasis on aspects of design that impact human health and wellness.

Unique to LEED is the opportunity to benchmark projects against an international set of peers. The rating system benefits from the efforts of volunteers and proponents from across the globe, who are all working to ensure that LEED is always evolving to drive the industry forward. For example, LEED has helped spur ongoing discussions about the choice of energy efficiency metrics by creating the Alternative Energy Performance Metric pilot credit, which allows project teams to evaluate performance based on source energy, primary energy, and GHG emissions.

The Energy Performance Metering Path Pilot Credit even allows project teams to meet energy efficiency requirements using actual building performance.

Toward Carbon While energy efficiency will always be a foundational tenet of any sustainable building’s design, the CaGBC believes that efforts to address GHG emissions must evolve to focus on carbon. This is why CaGBC worked closely with industry to launch the CaGBC Zero Carbon Building Standard (ZCB) in May of 2017.

Taking a carbon-centric approach is crucial because the most important factor in the emissions footprint of a building is often not energy performance, but rather the carbon intensity of the electricity and fossil fuels used. Recognizing the differences in electrical grids and fuels sources is critical to assessing impacts accurately and guiding investments.

12

FALL 2017 | BC FOCUS

Like the BC Step Code, the Zero Carbon Building Standard uses Energy Use Intensity (EUI) and Thermal Energy Demand Intensity (TEDI), however, the ZCB goes further by measuring carbon outcomes directly. This means that the Standard is not fuel agnostic - it drives choices about the types of energy that are used, and it encourages additional renewable energy generation both onsite and offsite.

As Canada’s first green building program to make carbon emissions the key indicator for building performance, the Zero Carbon Building Standard positions Canada in an elite group of countries working on similar initiatives, including Australia, France, Brazil and the US.

Finding Synergies The City of Vancouver’s Zero Emission Fire Hall is an example of a project seeking to better understand and benefit from the synergies of applying different sustainability requirements.

The project is seeking LEED and Passive Haus certification, and is participating as a pilot in the CaGBC’s Zero Carbon Building Standard.

The design of the Fire Hall will incorporate the generation of on-site renewable solar PV energy in order to offset greenhouse gas emissions, and the project is being used as a case study to develop best practices and approaches to designing future City of Vancouver owned buildings.

The CaGBC believes that while every project is different, there are invariably significant benefits to applying third-party green building rating systems like LEED and the Zero Carbon Building Standard in concert with the enhanced requirements of the BC Step Code. We look forward to working with municipalities and the private sector to help them determine how they can best improve building performance while maximizing emissions reductions.

The University of British Columbia’s Campus Energy Centre (CEC) is a state-of-the-art hot water boiler facility that provides for the campus heating requirements. Recently certified LEED Gold, this $24 million facility demonstrates leading edge sustainable design strategies and plays a significant role in reducing UBC’s GHG footprint. Its situation puts the campus’ energy infrastructure in the heart of the community, while its voyeuristic design makes the system within visible to students – a conscious choice made to elevate UBC’s awareness of their own energy consumption.

SUBMITTED BY DIALOG

UBC’s Campus Energy Centre is a major contributor to the University achieving its ambitious emissions target [1].

The University of British Columbia is recognized as a leader in advancing the global sustainability agenda – as steward of a large public institution, as educator of our future leaders, and as active participant in the search for ideas and solutions that will shape the province’s common future. In 2007 UBC made a bold commitment to reduce its greenhouse gas (GHG) emissions by 33% from its baseline, by 2015.

UBC’s Campus Energy Centre is major contributor to the University achieving its ambitious emissions target. Comprised of a new high-efficiency hot water heating plant and district hot-water distribution loop, the CEC replaces the pre-existing steam boiler plant constructed in 1925. The new system serves over 130 buildings, or 12,000 square feet of campus development delivered through 14 km of underground insulated pipe. The 20,000 square foot building houses all process equipment including three 15 MW boilers with capacity for phased expansion to a total output of 80 MW.

Sited on a prominent corner of Health Sciences Mall and Agronomy Road, the CEC replaces an existing surface parking lot, adjacent to the Life Sciences Building to the north, the Pharmaceutical Sciences Building to the east and the campus electrical sub-station to the south. The east faรงade of the CEC frames a public plaza that acts as connection point between the campus Health, Residential, and Sports precincts. Continuity of the campus fabric is reinforced by matching the street-wall setbacks and height datum established by adjacent buildings.

The building’s simple volume is enlivened by the play of light across and through the shroud by the selective use of three different types of panels – an opaque, a 30% perforated, and a 50% perforated panel. Further, the surface of the shroud tells a story where a higher intensity of perforation expresses process requirements for air exchange, ventilation or transparency. The zinc shroud also materially connects the CEC with both the Life Sciences and Pharmaceutical Sciences buildings.

On the west facade, the metal shroud has been peeled back to reveal the glazed skin of the 15m high boiler house providing pedestrians with views into the vaulted space of the process area and celebrating the building’s operation and process equipment through interpretative signage.

A building that breathes – the CEC inhales massive amounts of air to feed the combustion process and exhales hot, humid exhaust, while supporting a pulsing circulatory system that feeds hot water to campus buildings. The relationship between process equipment such as boilers, breeching exhaust, service rooms and hot water distribution equipment is driven by strict functional requirements.

The primary structure is constructed of cross-laminated timber (CLT) panels supported by glulam columns and beams [3]. The CEC inhales massive amounts of air to feed the combustion process and exhales hot, humid exhaust [4]. Pedestrians have views of the 15m high boiler house [5]. The Interior is naturally ventilated and well lit. Additional space conditioning is provided by waste process heat [6 and 7].

To unify these distinct programme elements and reconcile the many requirements for intake and exhaust louvres, vents and other service penetrations, a zinc metal shroud wraps the building perimeter.

This permeable skin, which floats 4m above the ground plane and is held off the building structure by one metre, was manipulated to provide transparency, weather protection and announce entry points.

Interior spaces are naturally ventilated and flooded with daylight, while additional space conditioning is provided by waste process heat. The primary structure is constructed of renewable, locally-sourced cross laminated timber (CLT) panels supported by glulam columns and 20m clear span beams. The CEC project redefines District Energy by making sustainable infrastructure that is visible and able to inform, educate and engage the campus community by speaking to both the process and broader energy issues.

NADLEH WHUT’ EN

Administration and Cultural Building SUBMITTED BY EUROLINE WINDOWS INC. PHOTOS Martin Knowles Photo/Media

The Nadleh Whut’en First Nation territory is located in north central British Columbia, near Fort Fraser, and covers about 5,000 square kilometers, including several reserves that are managed by the band. Nadleh, the main community, is located along the banks of the Nadleh River between Fraser Lake and the Nechako River. Nadleh Whut’en has a population of about 500 people, half of which live in Nadleh.

The Nadleh Whut’en, the “people who live where the salmon return”, have a strong connection with their ancestral heritage and are committed to stewardship of the land.

The new administration and cultural building – which houses the administration office, a health clinic, classrooms, recreation and assembly spaces, as well as a community kitchen – has been built with this stewardship in mind.

16

FALL 2017 | BC FOCUS

Although the Nadleh Whut’en administration and cultural building did not aim to achieve Passive House certification, the facility was built using green building principles, including Passive House concepts.

Windows only make up a relatively small part of the building envelope, yet up to 30% of heat can be lost through them, resulting not only in higher heating costs, but also reduced comfort for the occupants. In addition, moisture that collects on the inside of the window can lead to mold, which, in turn, can lead to health issues, especially for those already suffering from allergies, asthma, or a weakened immune system. This would be a serious concern anywhere, but even more so in a health clinic and classroom environment.

For this reason, EuroLine’s 4600-series uPVC tilt & turn windows with triple glazing were chosen for the project. With a 5-chamber frame, multi-point locking hardware, dual compression gasket, and LoE coated glazing with argon fill between the panes, they provide exceptional seal and insulation, keeping occupants comfortable even right next to windows. The warm edge SuperSpacer used in the insulated glass units helps virtually eliminate condensation on the interior of the windows, while the uPVC profiles are resistant to mold and mildew.

With a long service life requiring only minimal maintenance, uPVC windows also met the project’s longevity requirement. At the same time, the clay coloured profiles seamlessly blend into the structure and the environment, giving a sense of harmony between the building and the nature surrounding it.

2 Tell us about your career so far, and how you came to be working in the sustainability field.

Like many new graduates, I wasn’t sure what I wanted to do in terms of a career and it took me a while to make my foray in the sustainability field. I initially worked in microelectronics with a brief stint in LED lighting and realized that it wasn’t the best match for me. At the time, I was fortunate enough to come across the work of Buckminster Fuller and I enjoyed the way he explained sustainability by looking at the planet from a systems point of view. Over time, I started learning about the industry and volunteering with involved organizations. As I was connecting with people in the industry, I had a really spirited exchange with Joe Stano from Kane Consulting and he suggested that they had an intern opening in the company. After interning for two months, they offered me a permanent position and I was happy to accept.

How did you become involved as a volunteer with CaGBC? When I relocated to Vancouver, I knew I wanted to get involved but wasn’t sure where to start. I decided to attend a CaGBC mentoring event where I met Chris Higgins who was one of the mentors and a Green Building Planner at the City of Vancouver. He suggested that the best way to get involved and learn more about the industry was to start volunteering with the CaGBC and similar organizations. So I started off by volunteering at the 2015 CaGBC conference which was an excellent opportunity for me to get involved, meet industry professionals and attend education sessions. I also assisted in leading a Green Building tour for the conference, which was quite exciting and immersive for me at the time. Finally, I was contacted by the CaGBC (because I was on their mailing list) about an opportunity to volunteer for their Emerging Green Professionals program. I applied immediately and got accepted for the committee.

Tell us a little about the Emerging Green Professionals [EGP] program at CaGBC. The group is a space meant for the professional development of young professionals in the industry. The EGP Program offers a multitude of resources for young professionals by helping them network, connect with industry experts and gain access to educational sessions. As the BC Chapter Chair, I have had the opportunity to work with an amazing team of individuals in extending more opportunities for the professionals in the industry. In addition to organizing regular socials and networking events, we have offered a building research facility tour and a green building walking tour in 2017. Our next event this year is a mentoring event featuring a panel of industry leaders and experts. The goal is to create an opportunity for young professionals to learn about the different facets of the industry and to go about formulating a series of next steps on how to move forward. Becoming an EGP would be the perfect first step for a new graduate or a young professional in the industry because they would gain access to many resources as well as having a community of like-minded individuals to support them in their personal development.

Where do you see the future of green building headed in the near and more long-term future?

Given the prevailing green building standards and the new green building policies being adopted by cities, it will be interesting to see how the aesthetics of buildings and public space are affected.

While it certainly isn’t my background, I’m interested in seeing how architects are going to continue designing buildings of aesthetic value while staying true to some of the design constraints put forth to them. The hope is, of course, that we will see some extremely creative use of forms and clever articulations in the process – but time will tell. On the engineering side of things, I think the respective areas of materials and building automation and controls (lighting controls, in particular) look quite promising.

GROWING EV INFRASTRUCTURE at Vancity’s Head Office While greening building envelopes and implementing energy efficiencies has been a key focus for Vancity Credit Union, they are also acutely aware that it’s what happens inside those buildings and the behaviors of their staff that will really drive the greatest change. And for Canada’s largest community credit union, the staff behavior most greatly impacting greenhouse gas emissions is commuting – representing 52% of Vancity’s total GHG emissions. In order to tackle this issue Vancity has taken a multi-pronged approach to shifting commuting practices, including growing their Electric Vehicle (EV) infrastructure at their head office.

BY EMILY PEARSON - Portfolio Manager, Community Business & Investment, Vancity Credit Union

Around five years ago the first EV charging stations were installed and since then it’s grown to six stalls, serviced through three dual-charging stations. Sensing increased demand from staff and anticipating the shift in the marketplace, Vancity is now preparing to add in two more additional charging units, only this time they are graduating to Level 3 fast charging stations. Their hope is to be able to support a higher volume of vehicles with these charging stations, but are aware that it will require a change in behavior. “Typically staff are plugging in and leaving their vehicles for the work day, which makes sense for a Level 2 station. But with the Level 3 stations, staff will have to think of the stall as temporary and be sure to move their vehicle to make it available for the next user” says Immanuel Starchild, Manager of Facility Planning with Vancity’s Facilities and Environmental Management team.

20

Growing EV infrastructure also impacted the electrical grid at head office and in anticipation of the increase in charging stations, Vancity doubled their existing electrical room. “We needed a grid that would be able to meet the energy demands of these chargers and that could also manage the energy loads in a smarter way” says Starchild. “At the end of the day, we can offset this increase in energy through a variety of conservation measures and see it as a worthwhile investment given the impact it will have on the emissions from staff commuting.” Vancity offers an attractive financing incentive program for staff looking to purchase an EV vehicle and are expecting to see increased uptake as more affordable EV vehicles enter the market. They also offer subsidies for bicycles, bike repairs, and transit passes and ensure that wherever possible every office and branch is equipped with bike racks and showers for employees. “We hope to model a multi-pronged approach to greening commuting practices for other organizations and stay ahead of trends so that we can continue to influence the commuting choices of our staff” Starchild said.

“We want to see more buildings of this quality and design.”

745 THURLOW: Innovation and Efficiency with a View The new office building at 745 Thurlow does not readily look like a high-performance green building. There are no big solar panels, no iconic green walls, no local artisanal vegan restaurant. The greenness becomes visible in its performance which began with attention to efficiency and continues by delivering a great occupant experience. After one year, occupancy is 100% and the Energy Star score is 98. It has a walkscore of 99 and a transit score of 100. In this brief article we peel back layers of the building to showcase the innovative architectural design and the management practices which are delivering strong financial and sustainability performance.

QuadReal team members were part of the development team and QuadReal proudly manages 745 Thurlow, a property located in downtown Vancouver. The team targeted LEED Gold Core and Shell Certification, which it received in mid 2017. The 25-storey building replaced an older low-rise with retail at grade, adhering to strict height requirements and other typical restrictions of a downtown plot.

These features did not garner any LEED points but they did increase the envelope efficiency, the usable square footage and enhanced the views on the higher floors. While each of these elements added complexity and cost to the design and construction, they already seem well worth it. It means more people can work in a very efficient building that is optimally located for transit, walking and biking.

The most compelling features are exemplified by the view from the conference facility on the top floor. The building was initially slated to have 24 storeys, but an extra floor was possible by inserting post-tension cables in the concrete floors and reducing the interstitial space between the top of the T-bar ceiling and the floor above.

From an energy and water perspective there are several features common to LEED Gold such as high-efficiency mechanical equipment, rainwater capture, LED base lighting, low flow fixtures: nevertheless, the triple-glazed high- efficiency windows around the building are a bit ahead of its time. For health, the building has bike storage, changing rooms, lockers and a fitness centre. These features are the new normal for AAA office, which is a testament to the deep influence of LEED and the Green Building Council.

This means the space between floors was more efficiently used while providing greater space within each floor with no visible columns between the core and the perimeter of the building.

To accommodate the facade on the ground floor, the glass surrounding the building was placed at a slight angle, opening out as the building reaches the top floors. This allows space for the side walk and retail shops on the ground while lining up the top floor plate almost precisely with the property line of the building.

A key differentiator of the building is a very engaged management team which is actively monitoring energy, water and waste performance and constantly looking for ways to be even more efficient.

During this summer season, the management team organized free lunch hour yoga sessions, bike to work workshops, and a building step challenge using a social media platform to increase participation, all of which improve the health and wellness of tenants.

The response rate has been overwhelming - the yoga sessions held on the rooftop patio on sunny afternoons are often overbooked. By providing a healthy and balanced workspace environment, tenants are likely to experience increased productivity from their employees, with fewer sick days and absenteeism while enjoying higher satisfaction and retention rates.

745 Thurlow is fully occupied, has a high density of employees relative to older offices and still manages to use less than half the energy per square foot of average office buildings. The low utility cost and the low carbon footprint are valued by tenants, but no amount of data can beat the feeling from the top floor as you stand inside the conference room and look down Alberni street for a perfect view of Stanley Park, or the image of the sail boats on English Bay while doing Yoga on the rooftop patio. Making your professional home in a great building feels right and it comes together in those moments.

FALL 2017 | BC FOCUS

With a population of 18,000, the northern city of Fort St. John is the hub of British Columbia’s oil and gas industry. As the self-styled ‘Energetic City’, Fort St. John recognizes that an excellent source of energy is conservation.

This project is an exploration of what is achievable, even in an extreme climate, and serves as an example of the important role that municipalities can play in advancing energy conservation. At the time of completion in 2015, the building was only the third certified single-family Passive House project in Canada.

development as a sustainable neighbourhood. Passive Design strategies were used to maximize the thermal and environmental benefits through careful consideration of the thermal performance of building components and systems, minimizing heat losses in winter and heat gains in summer and maximizing energy efficiency.

Energy conservation is achieved through the use of high performance triple-pane wood windows, a prefabricated wood structure with cellulose and mineral wool insulation, and ultra air-tight construction. This minimizes the required size of mechanical and electrical systems, which include heat pump hot water and space heating and a 3.5KW photovoltaic array. Passive House design demands large south-facing windows to optimize solar heating.

The high-performance tilt and turn windows have an insulation value of R-9, eliminating draughts and cold spots. The Passive House design software permits detailed calculations of summer cooling loads, which have been optimized using solar shading and spectrally selective glass.

An energy recovery ventilation system ensures a continues supply of fresh, filtered air from the outside at a minimum rate of 0.3 air changes per hour, providing indoor air quality that is far superior to that in a conventional home. The PV panels generate enough power to run an air conditioner without purchasing additional electricity.

Air-source heat pumps with backup electric baseboards will emit 0.05 tonnes of GHGs per year — which represents a 99% reduction relative to a typical single-family detached dwelling. The 9KW photovoltaic system is anticipated to cover up to 50% of the electric energy consumed over the year - the remainder coming from hydroelectric sources. The heating/cooling cost for the year is estimated to be $200-$400, which amounts to annual savings of approximately $1,000-$1,800 compared to an average house in this climate.

The Fort St. John Passive House has achieved certification as a Passive House plus [PH+] through PHIUS. The building has an Energuide rating of 91 and an application for LEED Platinum certification is in progress. The project has been used to teach the local building community about Passive House construction and low-energy building design.

The house is a living classroom with public open houses, brochures, signs, workshops and website information. The project received the British Columbia Regional Award in the 2017 Canadian Green Building Awards, an annual program of SABMag and the CaGBC. See http://www.sabmagazine.com/winners2016.html
