Energy-intensive building

The Center for Environmental Education, adjoining the exotic gardens of Bouknadel, ... This is an operation initiated by the Mohammed VI Foundation for the Protection of the Environment, designed by Layla SKALI, accompanied on the environmental and development side by Bureau Veritas Morocco Group.

The CEE is an elegant building, contemporary very bright high-end; built in earth, bioclimatic design, made of raw materials assumed, it is at the forefront of technology serving ecology, well-being, comfort of use and health.

Another peculiarity for this project, which shows the evolution of organizational methods, especially thanks to digital. Technologies equip the building: Home automation, display screens of environmental indicators ...

A strong commitment to the environment
Another marker of this project, CEE is the first building testing the feasibility of setting up a Moroccan label for projects located in Morocco. Its architecture illustrates the commitment of the Mohammed VI Foundation for the protection of the environment and its partners in a process of sustainable construction and environmental labeling. The large glazed areas allow to work in natural light the maximum of time. High performance double glazing is equipped with blinds .......
Inside, the structure of the walls built in earth allows the storage of the heat and its slow restitution. The strength of this building is to achieve the objectives of Moroccan environmental labeling with a mostly isolated and efficient envelope, thanks to this combination of the inertia of the earth, the performance of glazing and home automation equipment. At the level of the outdoor gardens, 274 m² of photovoltaic panels of 168 modules provide the necessary energy for building operation and all its annexes with a coverage percentage of needs exceeding 90% (low demand) and more than 30 % (high demand). Finally, unlike Moroccan operations, a Wastewater Treatment Plant is installed to completely cover the watering needs of all the gardens and green spaces surrounding the Center.

Architectural description

A zero-loss passive architectural design meeting the targets below:

Eco - Construction: Integrated Choice of Processes and Construction Products / Clean Construction Site

Eco - Management: Energy / Water management, waste activities

Comfort: Hygro-thermal, acoustic, visual and olfactory

Health: Sanitary quality of spaces, air, water.

Expected results:

Realization of an ecological construction project inspired by Moroccan ancestral know-how in an environmental approach aiming at performance, energy efficiency and sustainability
Realization of an ecological construction project proposing a strong, functional and evolutionary integrated architecture.
Realization of an ecological construction project exploiting all renewable energy sources effective for the good operation of the center.
Obtaining an exemplary and demonstrative architecture, in terms of sustainable development, illustrating itself the ecological purpose. Rational exploitation of natural resources (land, water, air, wind), use of geothermal energy through a Canadian well, optimized water management, natural ventilation, use of wind power for point electricity generation (wind turbines), use of solar energy, solar street lights.

Energy consumption

Primary energy need : 259,00 kWhep/m².an
Primary energy need for standard building : 449,83 kWhep/m².an

Calculation method : Other

Final Energy : 81,99 kWhef/m².an

Breakdown for energy consumption :

Heating 2042.29 Kwh / year
Cooling 41049 Kwh / year
Interior lighting 38140,84 Kwh / year
ventilation 139 712.05

These data are based on a Dynamic Thermal Simulation study phase design (improved inputs and ambitious assumptions)

More information :

the actual consumption differs from the theoretical consumption, we did not perform any dynamic thermal simulation in the execution phase, however we have energy meters communicated to a centralized technical management (see photos), they indicate a consumption (17 MWH) the building is not yet busy regularly, we can share the annual consumption at the end of 2019,
The actual energy production by the installed PV system measured on June 13, 2019 is: 45 MWH in 2421 hours since system startup. (to see the photo)
