Main Results

  • Local energy production of 16.700 kWh through PV;
  • Reduction of 7,8 Ton of CO2e;
  • Production of 36 m2 of composting,  which was used instead of vegetable soil and generate savings of 4.032€;
  • Updated environmental information to all guests and employees is provided by the “Eco-Clock” which shows the real annual consumption of electricity, water, gas and related savings achieved by virtue of the efficiency measures implemented. 

Even at the energy production micro-level, the unit is a representative core with the installation of 36 PV panels of 240W, installed on 2 solar trackers, with a total production capacity of 8640W. The annual production obtained in 2011 was 16.700 kWh of energy from renewable sources, representing an economy of 1.837 € per year.


The creation of a low density hotel with a reduced land cover rate, enabling the development of nature and sustainable tourism, with a strong awareness focus, were the main conceptual premises for this project.

According to the principles of sustainable tourism, the Charming Hotel incidence is based on energy efficiency, renewable energy and use of natural resources, stands out the beginning of the operation of all the equipment associated with the efficient management of the basic features of the hotel (photovoltaic, solar thermal, geothermal, building automation, gray water recycling, etc).

Project details

Established on the West region of Portugal, the hotel is set within an area of approximately 55.000 m2 included in ecological classification perimeters of national scope, which conducted a long bureaucratic process with national authorities for nature, biodiversity and forest conservation, with the resolution through the formal permission of the construction in return for compensatory measures for the necessary conservation and maintenance of the ecological value of the site.

In this sense, the hotel develops actions to preserve this areas through the reduction of activities and anthropogenic pressure on the dunes, being already visible a significant recovery of specific species and habitats for the balance of the local ecosystem. In addition, the hotel carries guided tours by natural species rails and transmits information on the environmental recovery processes performed on site.

Being a hotel, it is restricted to the sector of tourism and leisure, and framed in the segment of low density thematic hotels, comprising 14 rooms, a penthouse and 4 villas. The hotel also features a restaurant, a grocery store, a screening room, SPA, an organic garden and a greenhouse for herbs production and events.

Based on the principles of sustainable tourism, the hotel serves as an exemplar construction by the set of micro-local production and innovative systems for the management and control of resource consumption. Auto-sufficiency concept is reflected in local systems of energy production and efficient resource management (PV, solar thermal, geothermal, building automation, gray water recovery, etc).

The creation of an innovative integrated automation and multimedia application allows the automation and control the electricity, water and sewage infrastructures from the hotel unit. This solution allows the generation of management information of all equipments and facilities of the unit using energy resources as well as monitoring the efficiencies obtained.

Briefly, the key success factors of this project development involve the creation of a luxurious low density unit with strong environmental awareness and an intervention and awareness role with the local community, its employees and guests. Additionally, the architectural language reflects the predominance of environmental choices at constructive solutions for low visual impact and complete integration with the surrounding landscape.
