01climate and situation

cold months:

We need PASSIVE SOLAR heating during December to February. During the coldest nights we also need to

use ACTIVE SOLAR heating

warm moths:

we need SOLAR PROTECTIONS at noons and central hours of April to October. The rest of the hours we

achieve the CONFORT CONDITIONS by the thermal internal earings due to the residences occupation

and the cross ventilation

strategies:

about passive heating by solar energy, we choose DIRECT CAPTATION SYSTEMS adapting the openings

characteristics, the framings and the glass, so that the solar radiation comes in and is accumulated in

the surrounding surfaces. The energy storage will happen in the mass of the materials that will build the

rooms: walls, ceilings, floors. The captation elements are also acumulating and regulating the CALORIFIC

ENERGY.

When we are in a location with a climate like the one we have in Barcelona, with our ADEQUATE ORI-

ENTATION and DESIGN it will NEVER be necessary to install air conditioning or conventional heating, we

could get the comfort conditions we want to have by less energy cost methods, mainly passive ones,

more sustainable and environmental friendly.

Strategies are applied to the project, with spaces open to SOUTH ORIENTATION to get the solar radia-

tion that helps improving ENERGY SAVING and COMFORT CONDITIONS, creating outside living spaces

protected from the wind and the excessive sun, using natural CROSS VENTILATION. Also the residences

have a high VOLUMETRIC COMPACITY, that helps to improve ENERGY SAVING.

PROJECT DESIGN PREMISE:

Every building is not just a privi-

leged site for the use of renew-

able energy, but also a natu-

ral place for storing energy, we

might consider turning buildings

into “NET GENERATORS”, ele-

ments to produce more energy

than the amount consumed, and,

using storage spaces, able to

manage their domestic demand

and surplus.

The RESIDENCES and the ATELIER are various prismatics volumes, just one or two floors with a north-south axis, helded over posts, and under it the earth maintains its natural aspect. It is accessed from the existing path, where the vehicule could be parked, be-side the housing.

CENTER: service spacesNORTH: romms SOUTH: all diaphanous common space for living-eating playing, with a covered porch.

On the roof we locate the obligatory thermal SOALR PANELS to obtain warm water.We also place ORCHARDS GARDENS to and vegetables will grow all year round with advantages of growing fresh food.

The project materials are as natural and ecological as possible. Resindeces are designed like real WOODEN BOXES, with horitzon-tal louvres.

About the INSTALLATIONS, we propose they have high efficiency and they use renovable energies.

The rain water is collected to be used for bathroom tanks and irrigation. We use HEATING FLOOR, as it works in low temperatures it is perfect to use the accumulated water from the thermal solar panels. The supplementary heater will work with BIOMASS (pellets), so we could say there are ZERO EMISSIONS. The organic residues and the ashes from the biomass heater will go to compostage piles, to obtain the fertilizer for the vegetables zone and the garden. The garden lighting will be done by solar energy lights

The land actions for drainage and earth support will be done mainly with biological engineering technics, where natural elements and alive vegetal materials are used for the works

GROUND FLOOR

We are projecting an ecological and low-cost housing getting comfort thanks to wood; witch has a favoura-ble thermal mass. We are using recy-cled wood for the structure and the skin of the residences. Between both we will place a humidity layer, an ecolo-gical isolation and a waterproof layer to achieve the optimal comfort level.
