MF ARCHITECTURAL
CONSULTANT

The multidisciplinary team of MF Consultant decided to focus their work and effort on the design and construction of buildings and cities under sustainable criteria and full capacity to generate and manage its own energy.

These days, thanks to the advanced technologies of Photovoltaic systems and its price, these systems are competitive compared to conventional energy supplying sytems.

From this effort the self-sufficient housing project in Fuerteventura arised, aimed at those individuals and families connected with nature and committed to a sustainable way of living and also attractive for professional developers interested in adding value to their customers and society.

THE ENVIRONMENT

¿WHY
FUERTEVENTURA?

Fuerteventura is a unique natural environment, declared as Biosphere Reserve by UNESCO in 2009, with some very unique natural and geographical features which have remained intact over the years.

North of the island, the area of Lajares, Villaverde, El Cotillo, Corralejo and La Oliva, is an environment surrounded by volcanoes and 'malpaís' of indescribable beauty. Here plots of 1,000 to 2,000 m2 predominate with the highest solar radiation rates of Spain. As a privileged offer of active leisure in touch with nature. (kitesurfing, surfing, windsurfing, SUP, diving, sailing, cycling, trekking,... )

For these geographical caracteristics, together with the support and input from residents of various areas of the Isle, we have decided to propose and develop our models for self-sufficient housing on this stunning Island.

THE HOUSE

Housing model

The housing models on which we have worked indicate possible designs and surfaces, but are completely adaptable to the needs and requirements of each client.

With these models we have developed a set of strategies in bioclimatic design, installation and construction solutions which allow us to achieve our goals of energy self-sufficiency and to define accurately the economic value of the materialization of the building together with all the negotiations and involved agents in the process.

The project characteristics which bring uniqueness and innovation are:

1 · A set location and particular climate.
The housing is designed to integrate formally and constructively at one location and its particular climate, the island of Fuerteventura.

2 · Bioclimatic criteria.
The design is made to provide the same level of comfort as a traditional house. Bioclimatic criteria have been followed for the construction itself, the materials used and the arrangement of its roof flights and elements, reduce energy loss of the building and enjoy maximum solar capacity in cold weather.

3 · Specific population.
The project is meant for a specific type of population, connected with nature and aware of the need of change in how to design, build, maintain and renovate buildings in order to establish a situation of improved environmental "benefits", economical and social.

4 · User interaction and adaptation habits.
Over its lifetime it will provide real data on the efficiency of the photovoltaic system for power generation and consumption habits of the occupants, immediate and accessible to the user, so that one can learn and adapt their habits in order to optimize the system.

5 · Control center, recommendations and optimization of daily consumption.
The control center of the system of generation and comsuption of energy, controls three parameters to achieve the most efficient usage: 1. Power generating installation. 2. Housing consumption at all times. 3. Interpretation of weather forecasting through Internet connection. With these three parameters recommendations are made for daily consumption and selected according to the peaks of energy production and battery power reserves whether or not to activate the increased consumption devices.

6 · Competitive economic impact go the photovoltaic system.
The economic impact of the photovoltaic system designed, based on the total investment in construction, representing a value of less than 10% of the budget of material execution, allowing the proposal to be very competitive with the costs of connection and power supply from tradicional connections.

BIOCLIMATIC STRATEGIES
INCORPORATED IN THE BUILDING

STRATEGIES

1 · Study of sunlight.
In designing, the building and its structural elements has been taken account sunbathe to control solar radiation that enters the building and at what point, so that roof flights and protections are calculated to optimize its use in the colder months and protect the inside int the warm months. Solar heights int the Canaries, with a latitude of 28 degrees N are, on december 21 at noon is 39.5º, closer to the horizon to the zenith. June 21 at noon is 85.5º, nearly overhead. On march 21 and september 21, 60º it is closer to the zenith to the horizon.

2 · Enclosure.
The walls are composed of elements that reduce inner-outer-inner energy transmissions over the parameters established in the Spanish Technical Building Code.

3 · Photovoltaic system.
The power supply is carried out autonomously by photovoltaic generation system, its consists of a number of solar panels determined by the total floor area of the property, for battery storage system and an information system and domestic control and connected to the forecast on the Web.

4 · Solar collectors for hot water.
The hot water is obtained by building solar collectors located on the roof, reinforce by electric heating, which are powered electrically by the photovoltaic system.

5 · Natural ventilation.
Natural ventilation of the house is enhanced by skylights on deck properly oriented to act by suction prevailing winds.

6 · Roof solutions.
The roof is the most exposed of the building to solar radiation element, which has opted for a solution isolates inverted roof with 80 mm wide and finishing with gravel to minimize the solar contributions.

7 · System information and control.
The information and control system of daily use makes recommendations based on the information available and optimizes system performance automatically based on the consumption limits previously set by the user. Connection has increased consumption devices to monitor their implementation in energy production peak times.

8 · Renewal of forced air enthalpy recovery.
The building has force ventilation as specified by the Spanish Technical Building Code. This system has been given an enthalpy recovery whose function is to acclimate the temperature of the inlet air to exit by connecting them via a coil to cancel the temperature difference between both.

9 · Floor high thermal inertia.
In coming to large glazed openings oriented Sur areas, local stone paving high thermal inertia acting in conjunction with the flights, so running in the cold months, they let in solar radiation through the glass and the rays strike the pavement of high thermal inertia, that it accumulates heat input and is ejected after the outdoor temperature has dropped to the element, helping raise few degrees night temperature inside the building in those months.

10/11 · Reuse of water.
The building has water reuse systems between devices inside and once outside the building target water purification system and are stored in a tank for reuse treated water for irrigation. Rainwater collected from the roofs and terraces are also directed to the storage tank once they have been filtered.

12 · Geothermal heating system.
Due to different temperatures that occur in the different municipalities throughout the year, by the difference in height above the sea, specially in the colder months, it has developed an optional air conditioning system using geothermal system connected to underfloor heating.

GENERATION SYSTEM
AND POWER CONTROL

The system of generation and energy management is designed with German and Italian systems first brands. We distinguish two parts of the installation:

A · On the plot (1)

Power generation is done through a number of photovoltaic panels installed on the field and whose dimensioning, as the entire system depends on the total square meters built in the building. The panels are connected to the investors and these in turn to the storage batteries, which will be located in specific for them and for other facilities that may not be in the open room.

B · Inside housing. (2/3/4/5).

In the interior of the house is the control center, with which it interacts through a touch screen on the wall or through any device connected to the Web. The control center has access to power generation, storage, consumption and the main consumer devices (lighting, appliances...)

The control center works with three parameters to optimize energy consumption:

1. Power generating installation.

2. Housing consumption at all times.

3. Interpretation of weather forecasting through Internet.

With these three parameters makes recommendations for daily consumption and selected according to the peaks of energy production and reserves of battery power when not activated or increased consumption devices. The user can set limits for daily consumption and the control center will be configured to not get over it and issue arm signals if the user habits are inconsistent with the established limits.

In short, the control center interacts with the user to adjust consumption patterns to sustainable and efficient without losing the current levels of comfort of conventional homes.

PROJECT

Housing models depending on built areas.

The housing models on which we have worked are approximate designs and surfaces about an hypothetic house, we will design an specific house for each client.

From these models we have developed a set of strategies bioclimatic design, installation and construction solutions that allow us to achieve our goals of energy self-sufficiency and to define accurately the economic value of the materialization of the building and all the negotiations and involved agents in the process.

The models are organized with the following nomenclature based on the floor area they own: L110/L120/L140/...

Each of the models has a financial economic analysis on the costs of construction, management and administrative taxes, fees technicians involved, insurance coverage works and study financing, amortization table, ROI and updated sales and rental prices.
