Owner approach of sustainability

BYMARO in agreement with the contracting authority wished to include the construction project of the University Hospital of BOUSKOURA in a sustainable development approach through the realization of a project that respects the environment, consumes little energy and offers a pleasant living environment for patients, their families and staff. The following environmental objectives have thus been set:

• Optimization of access to the site
• Limiting the overall energy consumption of buildings
• Water management on the site
• The attractiveness of open spaces and gardens
• Good waste management
• Comfort for patients, staff and visitors
• Good acoustic management between the different premises
• The assurance of a balanced, equitable, progressive and environmentally friendly development, both during the execution of the works and during the use and maintenance of the buildings.

BYMARO wanted to strengthen the anchoring of this operation in Sustainable Development, by proposing a project integrating all the environmental, economic and societal aspects required for the hospital of tomorrow.

In order to guarantee the achievement of its objectives, BYMARO has secured the services of a multidisciplinary team and a Sustainable Construction Project Owner. A Project Environmental Management system has been put in place to define the technical and human organization necessary to maintain the sustainable quality of the project.

Solutions enhancing nature free gains :

Establishment of an STD: design and implementation phases. Use of efficient production and ventilation systems with energy recovery. Use of a building envelope that performs better than regulatory requirements

Smart Building

BMS :

Presence of BMS and water and energy metering
Unlike a standard project, metering means per station for monitoring energy consumption will be put in place, in particular for:
 Heating,
 Cooling,
 Lighting,
 Ventilation,
 Domestic hot water.
A metering tree allowing the monitoring of water consumption according to the context of the building is planned.

Water management

The sanitary equipment chosen with a better performance compared to
water requirements that a standard project would have.
- For hospital rooms, the conventional reference water flow values
maximum to consider are the following:
 Flush: 6 liters / flush
 Urinal: 3 liters / flush
 Sink faucet: 10 liters / minute
 Shower: 12 liters / minute
- The recovery of rainwater for watering the green space.

Indoor Air quality

Implementation of a specific ventilation system (s).
Control of contamination in risk areas (2 to 4).

Comfort

Health & comfort :

Spaces frequented by patients for prolonged periods and sensitive to temperature rises are
equipped:
 Movable, adjustable exterior sun screens in hospital rooms.
 Night-time over-ventilation, allowing natural cooling of at least part of the spaces in the structure (sensitive to temperature rises).
Humidity control is provided in premises with device operating constraints
medical devices (for example MRI) or in premises with very specific long-term climatic conditions.

A natural lighting study was planned in the 1-bed and 2-bed hospital rooms ensuring the
Daylight Factor (DLF) level. Indeed, this study represents the assurance of an illumination
optimal naturalness while avoiding glare.

As part of the site survey, an identification of the sources of low-frequency electromagnetic wave and radiofrequency emissions is planned.

Access to daylight for all hospital rooms.

Sun protection that can be operated by users in hospital rooms and more particularly in rooms subject to the risk of dazzling from solar radiation

Respect of the normative values of illumination according to the types of spaces while putting more efficient equipment than ASHRAE standards.

Acoustic comfort :

An acoustic study carried out on the 6 criteria of acoustic environment below,
 Standardized weighted acoustic insulation vis-à-vis the outside space
 Equipment noise level
 Shock noise level
 Internal acoustics (based on specific internal acoustics indicators)
 Airborne noise isolation (in reception) from adjacent spaces
 Sound when walking

Acoustic support by an expert design office in the development of solutions to meet acoustic constraints.

Establishment of a program compatible with the objectives of the project

Implementation of an acoustic quality assurance plan integrated by Bymaro on site in the general site QAP: inter-room insulation, internal acoustic performance, noise control of technical equipment, compliance of noise pollution vis-à-vis neighbors.

Daylight factor : oui calculé supérieur ou égal à 1.2
