Clayton Community Centre Clayton Community Centre is North America’s first Passive House community centre, and Canada’s largest Passive House facility to date.
The community centre was built in response to the population and development growth in the Clayton neighborhood of Surrey, BC. The development of a new community hub was proposed in 2014. The new 76,000 ft² community hub integrates visual and performing arts, a 13,000 ft² neighborhood library, indoor basketball, volleyball and badminton courts, full gymnasium, fitness centre, and outdoor recreation spaces. The two-story centre serves as an ecofriendly facility that offers programs for all ages, all cultures, and all fitness levels.

Hackbridge Primary School Hackbridge is a new build primary school for 420 pupils aged 5-11 built next to the pioneering BedZED One Planet Living development. It is the UK’s first Passive House Plus certified facility and the first true net zero carbon school (regulated and unregulated).
To achieve Net Zero Carbon the design applies rigorous Passive House building envelope insulation and air tightness requirements, with triple glazed windows that enhance thermal comfort and provide excellent daylighting. Dynamic thermal modeling was carried out to ensure the orientation of the building was optimized for solar gains, reducing the risk of overheating and minimizing cooling requirements. Essential to the success of this project was the commitment to Net Zero by all stakeholders. Therefore, careful consideration was taken by architects and engineers, to select materials that are healthy, have low embodied energy and are easy to construct and maintain. This included the use of significant amounts of recycled materials. A highly efficient ground source heat pump (GSHP) system with inter-seasonal heat storage meets space heating demands and majority of domestic hot water demands.

Hackbridge Primary School © studiostagg To meet summer peaks and provide resiliency against climate change, the system also has a parallel heat exchanger to enable free cooling to be extracted from the ground. By extracting free cooling from the bore holes during the summer, this enables more efficient operation of the GSHP during winter and reduces energy demand overall. The building relies on a central air handling unit to distribute fresh air throughout the occupied rooms. The air is transferred from the occupied rooms to the main hall and WC rooms for extraction. This allows the overall volume of fresh air to be optimized and allows heat to be recovered from the whole building. Occupied rooms operate on a mixed mode basis so that the use of natural ventilation is encouraged when external temperatures are moderate. A rooftop Pv array provides renewable electricity to offset 100% annual energy demands, solar thermal panels meeting
80% of hot water needs. Location: London, uK Client: London Borough of Sutton Architect: Architype Construction Value: £10M Completion: 2019 Area: 2,000 SQM (GIA)

Integral Group worked together with urban design experts John Wardle Architects to accomplish the specific environmental agendas of this project: To design the residence following Passive House and Living Building Challenge principles.
This energy efficient residence was designed for a client with two passions in mind: contemporary architecture and cutting edge sustainability. The self-sufficient home achieves the core objectives of sustainability standards, within the context of Melbourne’s mild climate, greater variation in temperature and higher solar gains. Energy efficiencies are achieved by introducing the 5 main principles of: High Efficiency Glazing, High Level Insulation, Thermal bridge-free envelope, Airtightness and ventilation. The project team worked to deliver a seamless living environment by cladding the house with Mt Gambier limestone and other natural minerals, combined with technology that performed above regular sustainability standards to meet the client’s brief.
The project aimed to source as much of the materials from locations close to the site, and all timber products used are durable recycled Australian hardwoods.

For further north elevation in the stone surface, additional openings were carved out in front of a significant outdoor space, providing north sun that shines deep into the floor plan. These spaces allow for a unique connection to the backyard garden, and additional views of the house surrounds.
With Integral Group being one of the first commercial consultancies in the Australian market to promote the Passive House Standard, our team’s integrated approach to The Limestone House Project saw our engineers apply unparalleled expertise to the building technology, and further challenged conventional building and design
practice. Location: Melbourne, vIC, Australia Architect: John Wardle Architects Completion: 2019 Area: 675 SQM

The University of Toronto Scarborough student residence will be Canada’s largest Passive House project when complete.
The university of Toronto Scarborough Campus (uTSC) is constructing a new dormitory-style student residence on the uTSC campus to address increasing demand for on-campus accommodation. The proposed multi-storey residence building will be built north of Ellesmere Road and east of the planned rerouted Military Trail, a space that is currently occupied by 358 parking spaces. The 750-bed residence will include a mix of private and dormitory style accommodations. Additionally, the space will house a new 250-seat campus dining hall with kitchen facilities, commercial retail space, as well as student support and academic services, including the Student Housing and Residence Life offices.

Passive House standards have been incorporated into the Performance Output Specifications to ensure the building achieves very high energy efficiency. The building will feature air side heat recovery, variable refrigeration flow (vRF) systems, demand control kitchen ventilation and a highly insulated building envelope leading to reduced mechanical and electrical loads. It will also be Canada’s largest Passive House

Vancouver Fire Hall 17 Redevelopment When complete, Vancouver Fire Hall 17 will offer a 99.67% reduction in operational carbon emissions compared to the existing Fire Hall
This 19,375 ft² fire hall is the first Zero Carbon Building design (ZCB) certified fire hall in Canada, and the very first ZCB certified project in British Columbia. The Integral team was able to incorporate a number of design synergies to achieve the project’s ambitious sustainability goals. The mechanical systems consist of a geoexchange field coupled with ground source heat pumps that distribute heating and cooling water throughout the building. The high-performance building envelope allows for the geoexchange field to be a fifth of the size when compared to an equivalent building built to minimum code standards.
Right:

With the help of the Federation of Canadian Municipalities funding, Fire Hall 17 is installing a 95 kW solar photovoltaic array to help achieve net-zero energy in operation. The solar photovoltaic array provides the allelectric post-disaster fire hall the ability to remain operationally resilient in the wake of disaster by vastly reducing its
reliance on the grid. Location: vancouver, BC, Canada Architect: HCMA Architecture + Design Construction Value: $13M Completion: 2021 Area: 19,375 SF
