Energy-intensive building

General information

Positive energy and zero carbon building
Prizewinner of the PREBAT call for proposals

Program:

Offices and shops
85 housings
A nursery (capacity of 40 children)

This building hosts about 500 employee and hosues 300 residents.

Sustainable development approach of the project owner

- Positive energy and zero carbon building
- Prizewinner of the PREBAT call for proposals

Relationship of the building with its environment:
- Partial redistribution of the floor space to the public domain: a driveway for “soft” means of transportation though the center of the block. North-oriented little square in the continuity of the public area close to the tram station.
- Viewpoints and visual perspectives: a divided block in order to give multiple viewpoints to the pedestrians, to let natural light in and to avoid vis-à-vis.
- Bioclimatic approach to minimize needs and provide excellent thermal and visual comforts.

Choice of processes and construction products
- Entirely prefabricated frontage
- Central area in the ground

Comforts
- Summer and visual comfort: optimization of glazes surfaces thanks to a 80-meter-long southern façade. Consideration of sunlight: the tallest buildings are on the North, the smallest on the South to increase amount of sunlight in the block. A glazed patiois found in the center of the “Quadriplus” wing and glass atrium is used for circulation and as a connection to the “NEF” and “Quadriplus” wings. Indoor and outdoor moveable shading devices.
- Acoustic comfort: no false ceiling.

Operations and maintenance management:
An important work has been done over a period of 5 months to overcome difficulties of counting (wrong cabling of the CTM, no files creation, failing temperature sensors…) so that the measures reflect reality
- Monitoring and data analysis by Etamine as part of the PREBAT and implementation of corrective actions
- Monthly meetings of the steering group includingof the contractor, the engineering consultancy offices and users.
- Letters to the users to correct their behavior.

Miscellaneous
- Programmatic diversity: the building welcomes the main fields of the economy: inter-professional federations, social-service organizations (ethical banking, social housing – renting and buying), cooperative (organic food), construction companies
- Collaboration, social and environmental projects, local development…

Architectural description

Program:
Basement: 6900m² - 2 levels of parking (199 spaces for offices, 123 spaces for the housings).
Ground floor: 2,400m² divided between business and tertiary. 13,600 m² on 7 floors structured between 6 floors of offices and a 7th floor consists of 400m² of meeting rooms and common areas (gym, relaxation room, dining room) and 315m² of terraces (140 m² on the 6th floor and 175m² on the 7th).

Renewables & systems

Systems

Heating system :

Individual gas boiler
Combined Heat and Power
Low temperature floor heating
Radiant ceiling
Wood boiler

Hot water system :

Solar Thermal

Cooling system :

Floor cooling
Radiant ceiling
No cooling system

Ventilation system :

Double flow heat exchanger

Renewable systems :

Solar photovoltaic
Solar Thermal
Wood boiler

Other information on HVAC :

Heating - cooling: wood pellet boiler of 96 kW, reserve gas backup, vegetable oil cogeneration, active inert slab for heating and "natural" cooling using only groundwater. The system of active slab brings high inertia in summer and therefore a great comfort for the occupants.
Emission by the floor and ceiling (no false ceiling).
Grids separation between the facades.
Ventilation: double flow comfort ventilation with 80% energy recovery.
Direct and indirect lighting of offices ensure by individual masts. Very low installed lighting power (<5 W / mÂ²). Motion sensor and automatic gradation in accordance with natural light.

135m² of thermal solar collectors for housing hot water.
1600 m² of photovoltaic panels on the roof of the offices and housing (228 kWp).
Electrical production: 213,000 kWh by photovoltaic system and 133,000 kWh by cogeneration

Smart Building

BMS :

BMC associated to 300 gauges (temperature, humidity, consumption)

Environment

Urban environment

Access by public transportation: T3 tramline, metroline A;
Park and Ride of 470 parking lots for cars and 470 others for bikes.
RhônExpress, link between Part Dieu Station and Saint Exupery airport.
