Architectural:

Height is measured from the level of the lowest, significant, open-air, pedestrian entrance to the architectural top of the building, including spires, but not including antennae, signage, flag poles or other functional-technical equipment. This measurement is the most widely utilized and is employed to define the Council on Tall Buildings and Urban Habitat (CTBUH) rankings of the "World's Tallest Buildings."

114.9 m / 377 ft
Floors
Above Ground

The number of floors above ground should include the ground floor level and be the number of main floors above ground, including any significant mezzanine floors and major mechanical plant floors. Mechanical mezzanines should not be included if they have a significantly smaller floor area than the major floors below. Similarly, mechanical penthouses or plant rooms protruding above the general roof area should not be counted. Note: CTBUH floor counts may differ from published accounts, as it is common in some regions of the world for certain floor levels not to be included (e.g., the level 4, 14, 24, etc. in Hong Kong).

Type
CTBUH collects data on two major types of tall structures: 'Buildings' and 'Telecommunications / Observation Towers.' A 'Building' is a structure where at least 50% of the height is occupied by usable floor area. A 'Telecommunications / Observation Tower' is a structure where less than 50% of the structure's height is occupied by usable floor area. Only 'Buildings' are eligible for the CTBUH 'Tallest Buildings' lists.

Function
A single-function tall building is defined as one where 85% or more of its usable floor area is dedicated to a single usage. Thus a building with 90% office floor area would be said to be an "office" building, irrespective of other minor functions it may also contain.

A mixed-use tall building contains two or more functions (or uses), where each of the functions occupy a significant proportion of the tower's total space. Support areas such as car parks and mechanical plant space do not constitute mixed-use functions. Functions are denoted on CTBUH "Tallest Building" lists in descending order, e.g., "hotel/office" indicates hotel function above office function.

office

Structural Material
Steel
Both the main vertical/lateral structural elements and the floor spanning systems are constructed from steel. Note that a building of steel construction with a floor system of concrete planks or concrete slab on top of steel beams is still considered a “steel” structure as the concrete elements are not acting as the primary structure.

Reinforced Concrete
Both the main vertical/lateral structural elements and the floor spanning systems are constructed from concrete which has been cast in place and utilizes steel reinforcement bars.

Precast Concrete
Both the main vertical/lateral structural elements and the floor spanning system are constructed from steel reinforced concrete which has been precast as individual components and assembled together on-site.

Mixed-Structure
Utilizes distinct systems (e.g. steel, concrete, timber), one on top of the other. For example, a steel/concrete indicates a steel structural system located on top of a concrete structural system, with the opposite true of concrete/steel.

Composite
A combination of materials (e.g. steel, concrete, timber) are used together in the main structural elements. Examples include buildings which utilize: steel columns with a floor system of reinforced concrete beams; a steel frame system with a concrete core; concrete-encased steel columns; concrete-filled steel tubes; etc. Where known, the CTBUH database breaks out the materials used in a composite building’s core, columns, and floor spanning separately.

About Manitoba Hydro Place

Manitoba Hydro is the major energy utility in the Province of Manitoba, the fourth largest energy utility in Canada and it offers some of the lowest electricity rates in the world. Owned by the provincial government, nearly all of its electricity comes from self-renewing water power. Its new headquarters tower, Manitoba Hydro Place, is the first of the next generation of sustainable buildings that integrated time-tested environmental concepts with advanced technologies to achieve a “living building” that dynamically responds to the local climate.

Located in downtown Winnipeg, the city is known for its extreme climate, with temperatures that fluctuate from -35ºC (-31ºF) to +34ºC (95ºF) over the year. The tower is targeting less than 100 kWh/m²/annum compared to 400 kWh/m²/annum for a typical large scale North American office tower located in a more temperate climate. The architectural solution clearly responds to the client’s vision, and relies on passive free energy without compromising on design quality and, most importantly, human comfort.

The street address, 360 Portage Avenue, encapsulates the three-hundred and sixty degree approach of the formal Integrated Design Process (IDP) mandated by the client to achieve the objectives of 60% energy savings, supportive workplace, urban revitalization, signature architecture and cost effectiveness. The site was strategically selected because over 95% of the bus routes pass this address, including routes to suburban Winnipeg where 80% of Manitoba Hydro employees live. The IDP process was greatly enhanced by extensive computer modeling using local wind, sun and temperature data to evaluate design options. The building is already projected to outperform its original energy goal by 64% or higher.

Embraced and nicknamed the “Open Book” by citizens of Winnipeg, the tower design forms a capital ‘A’; composed of two 18-story office towers which rest on a stepped, three-story, street-scaled podium. The towers converge at the north and splay open to the south for maximum exposure to the abundant sunlight and consistently-robust southerly winds unique to Winnipeg’s climate. The podium includes a publicly accessible Galleria to offer citizens a sheltered pedestrian route through the full city block. Narrow floor plates and tall floor-to-ceiling glazing allow sunlight to penetrate into the core. A double façade curtain-wall system forms a one meter (3ft) wide buffer zone. It is comprised of a double-glazed outer wall and a single-glazed inner wall which insulates the building against heat and cold. Automated louver shades control glare and heat gain while radiant slabs act as an internal heat exchange with the geothermal field.

A tall solar chimney marks the north elevation and main entrance on Portage Avenue, and establishes an iconic presence for Manitoba Hydro on the skyline. The solar chimney is a key element in the passive ventilation system which relies on the natural stack effect to draw used air out of the building during the shoulder seasons and summer months. In winter, exhaust air is drawn to the bottom of the solar chimney by fans, and heat recovered from this exhaust air is used to warm the parkade and to preheat the incoming cold air in the south atria.

In contrast to conventional North American office buildings which use re-circulated air, Manitoba Hydro Place is filled with 100% fresh air, 24 hours a day, year round, regardless of outside temperatures. Within the splay of the two towers, a series of three, six-story south atria, or winter gardens, form the lungs of the building, drawing in outside air and pre-conditioning it before it enters the workspaces through adjustable vents in the raised floor. Depending on the season, a 24 meter (78ft) tall waterfall feature in each of the atria humidifies or dehumidifies the incoming air. During colder temperatures, recovered heat from exhaust air, and passive solar radiant energy are used to warm the fresh air. The conditioned air is drawn through the floors into the offices through under-floor fan units. Building occupants, computers and other sources of heat cause the air to rise, which is then drawn north and exhausted by the solar chimney. In the shoulder seasons, the building relies solely on outdoor fresh air through automatic and manually-operated windows.
Manitoba Hydro Place also has the largest closed loop geothermal system in the province. Two hundred and eighty boreholes, each 150 mm (6in) in diameter, penetrate the site 125 meters (400ft) underground, circulating glycol which is cooled in the summer and heated in the winter by the ground source heat exchanger. Water is circulated through the heat exchanger and distributed through the thermal mass of the concrete structure which in turn heats or cools the space consistently.

Manually operated windows on the interior curtain wall, combined with the automated exterior wall vents, allow employees to control their individual environment. This elemental detail reflects Manitoba Hydro’s commitment to the well-being of its employees, as well as supporting goals of improved productivity and reduced absenteeism. Workstations and glass enclosed meeting spaces are organized into neighborhoods around each atrium to support individual and team-centered work processes. In both the north and south atria, interconnecting stairs promote physical activity, reduce reliance on elevators and provide opportunities for interaction between divisions.

The podium rooftops feature deep soil intensive green roofs and accessible terraces, creating a lush landscaped outdoor amenity for employees, while also reducing storm water runoff and providing additional thermal insulation. A reflective coating on the tower rooftops reduces the summer season cooling load and the urban heat island effect.

Manitoba Hydro is as invested in creating a supportive workplace and revitalizing Winnipeg’s downtown as it is in achieving energy savings and signature architecture. The building connects to the city’s elevated sheltered pedestrian network. In the former head office, located in the suburbs of Winnipeg, 95% of the employees drove to work alone. In anticipation of the transition, Manitoba Hydro secured a number of parking stalls downtown. At the same time, it created various incentives, including corporate participation in the Transit EcoPass program to encourage employee use of public transit. Six months after moving into the new building, more than 50% of relocated employees are leaving their cars at home. As a result, Manitoba Hydro has been able to reduce its parking spots and has observed a five-fold increase in employee use of public transit compared to the previous year. Qualitatively, employees are reporting that they are enjoying time gained to read and socialize with colleagues.

With a vested interest in the downtown, leasing opportunities in the base building are limited in an effort to stimulate the support of local businesses, and to encourage staff to experience their city. Restaurants and bars are already reporting a significant increase in revenue as a result of the influx of over 1600 Hydro employees to the area.

Ultimately, Manitoba Hydro Place sets a precedent for the seamless integration of architectural excellence and climate-responsive, energy-efficient and sustainable design while enhancing and improving the quality and comfort of the human experience and the civility of urban life.
