Energy consumption

• Primary energy need : 156,00 kWhpe/m².year

Calculation method : Other

Breakdown for energy consumption :

No repartition is made as the building has only one energy meter.

• Initial consumption : 350,00 kWhpe/m².year

Envelope performance

• Envelope U-Value : 0,60 W.m^-2.K^-1
More information :

External walls are not insulated and composed of brick and concrete. Windows are triple-glass on the north section while the south is double-glass. 

Roof is insulated with 2 cm polystyrene.

Note that the air tightness value is calculated using the Canadian energy code NEBC 2011 and the units are L/sm2 (0.25)

• Building Compactness Coefficient : 0,20

Indicator : I4

• Air Tightness Value : 0,25

Real final energy consumption

Final Energy : 120,00 kWhfe/m².year

Systems

Heating system :
• Boiler fuel
• Heat pump
• Water radiator
• Low temperature floor heating
• VAV System
• Solar thermal
Hot water system :
• Individual electric boiler
Cooling system :
• Reversible heat pump
• Fan coil
• VRV Syst. (Variable refrigerant Volume)
Ventilation system :

Other information on HVAC :

- Heating. Air-to-water heat pumps coupled with a solar wall collector, thermal storage and electric boiler backup
- DHW (domestic hot water). Electric storage tanks
- Cooling. Air-to-water heat pumps
- Ventilation. Double flow with energy recovery >80%.
- Renewable energy. Heat pumps and photovoltaic panels

One of the strategies used to reduce the energy consumption of the building's heating system was the integration of a solar wall on the south façade. It allows for passive heat collection (high sunlight levels, especially on the coldest days). The outside air, which can reach -25°C, is preheated in this wall and then used by the heat pumps. The output is therefore stable even during the coldest periods. The building also has a photovoltaic production on the roof (375 panels) which not only allows a large part of the energy produced to be consumed by the building itself, but also limits the demand for power through a storage system. The savings observed are of the order of 30% of the building's energy bill. It should be noted that in Quebec, the network manager charges a significant amount for the power demand, and this cost can represent half of the energy bill. With the system implemented in the Phenix, the gains observed are considerable.

Urban environment

The building is located in Saint-Henri, in Montréal, which offers an access to all the services but is also central for public transportation (bus and metro) as well a biking paths. The building is well integrated into the neighbourhood in order to encourage employees to prioritize public or active means of transporation.

Construction and exploitation costs

• Total cost of the building : 3 391 855 €

Energy bill

• Forecasted energy bill/year : 74 719,43 €

Real energy cost/m2 : 9.34

Real energy cost/Work station : 186.8

Indoor Air quality

As part of the LEED certification, the building was subjected to air quality measurements using passive radiello sensors. Fine particles, formaldehyde and total VOCs were measured at the end of the construction.

In the same way, the following strategies have been integrated

• An indoor air quality management plan
• Specification of low VOC (volatile organic compound) and low emission materials
• MERV 13 high efficiency air filters
• CO2 detectors in meeting rooms to optimise the supply of fresh air

Quality of life and services

The following strategies have been integrated to assure quality of life and services for the occupants:

Comfort :

• Heat detectors to ensure occupant comfort
• Water filters to provide quality drinking water
• Multifunctional relaxation areas

An active environment :

• An active design that prominently features the main staircase connecting all floors, as opposed to the lift
• A gym and activity programme
• Bicycle parking to promote active transportation

Carbon sink

A Life Cycle Assessment was carried out. It consisted in comparing the existing building with the future building in order to determine the reductions obtained thanks to the reuse of the building 65% reduction was calculated by an independent company (AGÉCO)

Initiatives promoting low-carbon mobility

The building is located in Saint-Henri, in Montréal, which offers an access to all the services but is also central for public transportation (bus and metro) as well a biking paths. The building is well integrated into the neighbourhood in order to encourage employees to prioritize public or active means of transporation and reduce carbon emissions.
