Owner approach of sustainability

Sol House Taghazout bay is a component part of the project to develop the Taghazout Tourist Station, which itself is part of the Azur Plan and more widely within the framework of the tourism development strategy "Vision 2020". The SAPST, a development and promotion agency for the Taghazout station (SAPST), fully adheres to this national strategy, which consists of a responsible approach that has set itself three main objectives: * To preserve the culture, values, Traditions and identity, * Protecting the environment, * Working for tourism as a vehicle for economic and social development. In order to confirm its commitment to this strategy and its commitment to sustainable development, SAPST decided to An integrated approach, namely: * QSE approach (For all activities and processes of the SAPST) * HQE approach for development (for the entire station) * HQE approach Residential (for the residential component) Residences (for hotels such as Sol House Taghazout bay) * Green Globe approach (Golf, Hyatt Place hotel and Sol House Taghazout Bay hotel) All these approaches, which are different and complementary, and which form the core of the SAPST Management System, affect all aspects of sustainable development while placing the environmental component as a core to which they converge.

Architectural description

The architectural concept of the village has been defined in such a way as to follow a logic of eco-construction. The buildings are entirely oriented south with large openings which allow a real saving of energy in winter while protecting themselves from the summer rays by judiciously sized sun protection. Volumetry does not exceed R + 1 for dorms and surf academy; And the compactness of the buildings makes it possible to control and reduce the energy consumption by limiting the losses. The roofs of the accommodation constitute an advance that goes beyond the walls and acts like sun breezes. The latter attenuate the rays of the sun in summer in order to reduce the rise in temperatures inside the buildings. In winter, they allow the radiation to penetrate to take advantage of calories. These solar protections are made up of solid parts and perforated parts allowing to benefit from the natural illumination to the maximum.

Breakdown for energy consumption :

Detailed consumption by item was calculated by the STD (Dynamic Thermal Simulation) (see enclosure)

More information :

On this operation, a dynamic thermal simulation was carried out in order to simulate the energy responses of the different buildings of the surf village. The objective of this study is to optimize the energy efficiency of the buildings, while preserving the level and the quality of the comfort of use. Thus, primary energy consumption is at least 25% lower than that of a standard building, according to Moroccan thermal regulations. Several steps have been taken to achieve these results. In the first place, the building envelope has been well-cared for: thermal insulation of roofs, walls and low floors, use of double glazing at the level of the accommodation, optimization of openings to take advantage of natural lighting, .... These so-called passive solutions make it possible to limit the energy requirements of buildings for heating, cooling and lighting. On the other hand, high-performance equipment has been selected. In terms of lighting, the choice of luminaires has been made in such a way as to reduce energy consumption and ensure optimum comfort for the user, including LED lamps for outdoor lighting and car parks, Photosensitive cells to activate artificial lighting according to natural lighting, etc. In addition, solar energy is used to heat the sanitary water in the dormitories, the restaurant and the surf academy. A real energy saving. Finally, energy consumption is monitored at the level of each building, by means of the installation of separate meters, by zone, also allowing the detection of overconsumption directly in the areas concerned. Several meters have been set up and distributed as follows: • Restaurant • Surf Academy • Kitchen • Accommodation (dormitories 1 and 2) • Accommodation (75 wooden bungalows) • Surf Shop

Other information on HVAC :

Heating, cooling: On all buildings, heating and cooling are ensured by means of reversible splits, with the exception of the restaurant where a duct system is installed. The set temperatures are 19 ° C in winter and 26 ° C in summer, which can be adjusted, depending on the user's needs, from +3 to -3 ° C. The water of the dormitories, the surf academy and the restaurant is heated thanks to 66 m² of solar panels located on the roof. Ventilation: All buildings except the bungalows, are mechanically ventilated by single flow air treatment plants: The fresh air enters through the mouths located in the joineries, and the extraction is carried out in the humid rooms (sanitary, ... ). The restaurant is ventilated by means of a two-flow power station located on the ground floor, which, in addition to its role of air exchange, makes it possible to filter incoming air. These systems ensure a satisfactory air change rate even when doors and windows are closed.

Life Cycle Analysis

Eco-design material : Use of FSC-certified wood as the main material at the level of dwellings

Water management

• Consumption from water network : 40 663,00 m³
• Consumption of grey water : 5 110,00 m³

Water Self Sufficiency Index : 0.11

Water Consumption/m2 : 6.57

Water Consumption/none : 542.17

Water consumption is controlled through the installation of water-saving systems for sanitary appliances, mainly: -WC double flushing 3 / 6L - low-flow flushing 6,6lpm - low flow rate 9,6l - Aerators at the level of the mixing valves. Water metering is also monitored by counting as follows: • 1 meter for the bungalows • 1 meter for the restaurant • 1 meter for the reception • 1 counter for the surf academy • 2 meters for the bungalows Level of the dormitories On the other hand, the waterproofing of the floors has been reduced to the maximum. Vegetated areas and permeable soils (car parks, approaches) allow the infiltration of rainwater in order to respect the natural cycle of water. The selected species are endemic, local and non-allergenic, their adaptation to the climate of the site reduces their need for watering, which is also ensured by the use of treated water at the treatment plant (STEP) .

Indoor Air quality

All the buildings except the bungalows are mechanically ventilated by single flow air treatment plants: The fresh air enters through the vents located in the joineries and the extraction is carried out in the humid rooms. The restaurant is ventilated by means of a two-flow power station located on the ground floor, which, in addition to its role of air exchange, makes it possible to filter incoming air. These systems ensure a satisfactory air change rate even when doors and windows are closed. On the other hand, in some rooms (yoga room, classroom, gym) facing the sea, they are double-oriented and naturally ventilated by the opening of large windows, but without CMV, CO2 detectors have been installed to measure the ambient air quality and alert the occupants if the tolerated threshold is exceeded.

Comfort

Health & comfort : The local climate is characterized by a semi-aridity which means that summer temperatures are relatively high. This has been taken into account in the design of buildings in order to limit the energy and environmental impact associated with excessive air conditioning. In winter, however, heating requirements remain limited. Indoor temperatures do not fall below 11-12 ° c. Accommodation has been designed to benefit from solar inputs in winter while limiting their impact during the summer period; During the summer period the eaves serve as solar shading: they limit the solar contributions and thus the need for cooling (air conditioning). During the winter period the rays of the sun have a lower inclination: they are not stopped by the eaves, they are instead source of heat and light. The accommodation as well as all the spaces of the establishment have numerous openings which allows to benefit from a natural light that is very powerful and allow the occupants to make use as little as possible of the artificial lighting.

Measured indoor CO2 concentration :

Des détecteurs de CO2 ont été installés dans les locaux de l'académie de surf qui permettent de mesurer en permanence la concentration de CO2 présente dans ces locaux et qui ne dépasse jamais 1000 ppm.

Calculated thermal comfort : Le confort thermique a été calculé grâce à la Simulation thermique Dynamique avec les hypothèses suivantes : En ce qui concerne les Hébergements, les Dortoirs et le Restaurant, les scenarii de chauffage et de refroidissement sont : - Chauffage : Consigne

Acoustic comfort : An acoustic instruction was written during which the acoustician issued prescriptions to improve the acoustics at the level of the different spaces. The main elements taken into account are: - Standardized acoustic insulation weighted with respect to the external space - Noise level of the equipment - Shock noise level - Internal acoustics (based on specific indicators of internal acoustics ) - Isolation to airborne noise (in reception) with respect to adjacent spaces - Tone at walking

Urban environment

* Location: The surf village is composed of several buildings that are scattered on the plot. The low COS (15%), the low height of the buildings (R + 1) associated with this sparse installation of buildings makes it impossible to create a dense urban area. This implantation thus promotes the circulation of the air and thus reduces the heating of the urban substratum. * Vegetation: The site is characterized by a natural forest ecosystem dominated by the argan tree. This endemic essence of Morocco plays a decisive role in the preservation of biodiversity and the great ecological balances. However, it is characterized by advanced stages of degradation. The surfing village is located on a protected area of ​​the argan tree. This is an area classified as UVB1 (ie the protection level is the strictest). In this area, the argan plant is very dense and rich in floristic species. The Landscape concept of the Surf Village builds on and extends the work carried out in the Public Spaces: a kind of vegetal mimicry and ambiances, identity for the natural site of the resort. The materials used, as well as the associated plant palette, have been chosen specifically for their local presence (dry stone walls / thick pebbles / eucalyptus candles ...) * Transport: Restricted access to the motor vehicle site, limited to Service vehicles and firefighters, also reduces the production of heat and especially air pollution. This restricted access has also made it possible to limit the bitumen zones and thus limit the minerality of the site. * Access: The site is accessible via 2 public transport lines, namely: • LINE 32: AGADIR - TAGHAZOUT • LINE 33: AGADIR - TAMRI With a frequency of 4 buses per hour On the other hand, Access to the level of Taghazout station bay and reduce the flow of cars, two free electric shuttles will be set up, eventually, and will also serve the surf village.
