Furniture - House Design and Decoration @ RoomU.net

From the outset, the project of 40 houses for rent in Torrevieja couple was considered by the developer, the IVVSA as its pilot project sustainable. Wanted to understand the possibilities of housing VPO "sustainable" and added costs. Prior to the presentation of the first drawings of writing a report which explained the possible improvements to a standard dwelling, together with an estimate of costs. In this way, the developer had a document to decide where to invest in improving the quality and avoid unnecessary discussions and subsequent changes, as was going to be a learning process for both the developer for the construction and technical equipment.

We present a coherent project with 5 points "sustainable" which guide our work in the office: an introduction and setup to ventilate the house in a natural thermal insulation in walls and roofs to reduce heat losses, retraining greywater for irrigation, the application of industrial materials and construction systems and dry, and a reduction of waste production on site. In each of these points have improved somewhat with respect to the reference current constructive.

The order by the promoter was simple and clear: a program to fit 40 dwellings of 2 bedrooms, garage, meeting the requirements of VPO, and a budget for implementation of material of approximately 480 € / m2. The planning policy indicated a PB +1 height, setbacks from a 5 m at all boundaries, a building 0.63m2t/m2s and an occupation of 40%.

1. The transformation of the place The sun is a rectangle with its major axis oriented east-west with access from the street on the west façade. The neighbors did not provide references to take into account and decide to dump the project into the interior. The definitive on-site is determined by the configuration of 4 blocks around a central space in parallel with the edge 4.

Each block contains 8 or 16 houses. Composition was chosen in order to work with comb private patios and a cross ventilation. Each house has its own entry from space using a central setbacks in the façade and an escalation to the first floor. The ground floor houses in turn mainly to the edges of the plot by converting the remaining space 5m perimeter in a more private space. The houses on the first floor have their main view towards the central square. All houses have their own private patio of approximately 13 m2, an increase by 20% of the usable area of each dwelling.

The topography of the terrain is fairly flat with a slight rise on the southeast corner. Each of the four blocks has its own topographic elevation ground floor there are 40 cm apart between each of them, which creates a natural slope in the pavement of the central common space that serves to collect rainwater. Throughout the solar space only for access to a shelter and an emergency are paved, the rest is a soft, permeable soil. Of 4810 m2 of land, only 1590 m2 land have become hard, the rest are 3220 m2 of topsoil, gravel garden or deck.

Little things like certain groups of banks under the trees, a ping-pong, or the possibility of hanging swings in private patios, will improve life in this social housing complex for youth, having spent a fraction of the budget to "accessories".

2. The choice of materials
Opted for a dry construction in order to work more precisely, with industrial materials, faster and with less waste. The structure of metal beams and pillars with wrought alveolar plate. The surface of the front panel is a lightweight reinforced with fiberglass and lightweight aggregate like expanded clay granules and granulated foam glass recycling. These panels are mounted dry on a light metal structure.

The outside is a plastering mortar 5 to 6 mm. Among the metal sections of the facade was placed 7 cm of thermal insulation of fiberglass with a minimum density of 32 kg/m3. This composition of the walls XTERNAL reduces the total thickness (including structure) to 21 cm, resulting in a gain of 2 to 3 m2 (or 4%) of floor space per dwelling in respect of a house with a facade of 30 cm thick, with no additional cost. The walls run with a dry plasterboard panels on roofs and leaving the alveolar plates painted white view, which avoids in plastering work, implies a lower consumption of water, a gain of time and a reduction waste.

The decks are covered with green cistern to reduce the maximum transmission of heat or cold from inside to outside or vice versa. For the remaining items have been chosen standard materials of good quality: a stoneware uniform throughout the soil for housing, interior carpentry of wood, aluminum exterior carpentry 4/6/4 crystals, etc..

3. Energy consumption
A good energy management means first trying to reduce the need to manipulate the natural temperature inside the house. It is absolutely necessary to ventilate the house in an easy and natural. It's the best way to get rid of excess heat and heat the interior air is less power if it is renewed and fresh air to stagnant and polluted air.

Eaves on the south facade and the trees in front of the west facade avoid overheating the interior. In second place come the added technology, including increased thermal insulation up to 7 cm, or cover well. Torrevieja has a mild climate in winter, so the program does not provide a heating needs widespread. However, we have provided a separate power line to each house in every which provides the possibility of a hung electric heating.

By opting for a stay is individualized heating can turn on or turn off the heat as needed for each location. It has provided each household with a solar panel for producing hot water. Was chosen for a horizontal plate running through the "drain back", with an area of 2.50 m2 per dwelling, and a 150 l tank with an electrical resistance as support for the solar panel.

4. Water management
Water management is a complex management that requires the agreement of several agencies and individuals. For example, the management of rain water in a climate with heavy rainfall and a city law that requires to keep rain water area, it is almost impossible. This management requires large municipal reservoirs to collect rainwater. A private advocacy has little to do there. The only thing we have planned in this regard is the well casing that contains a certain amount of rainwater and the excess water will have to go to the street, but at least it in more and less violent.

As Torrevieja has a dry climate and the amount of rainfall is not sufficient to feed the covers well, has installed a greywater treatment plant for the 8 houses that are above the garage. Each household consumes about 200 l / day in bathrooms, showers and toilets, which are gray water with small amounts of soap. Is to estimate the amount of water needed for a drip irrigation system in 1litro/m2/día. Well you need a cover for not less losses to evaporation, so that the recycled 1600 liters per day is enough to feed all the covers. This will offer the user a housing covered with optimum thermal insulation without excessive consumption of water.

The only device in the house that has entered the toilet with dual flush discharge as basic installation, something that we added to the list of requirements for the developer.

5. Waste management
Waste management is the least known and developed in the way towards a more sustainable construction. Waste no value and no owner is going to run at almost 90% of RCDs, be deposited in a landfill, whether or not controlled. Until the law and industry will not invest more on the subject, all we can do is to minimize the production of construction waste on site. Earlier in the section on the choice of materials, we have already mentioned that wherever possible we opt for a dry construction, industrial nation. The amount of waste is much lower than in a standard work.

Concerning municipal waste, the kitchens have been designed so that, while the minimum size, one of the cabinets containing a set of 4 cubes to separate plastic, glass, cardboard and the rest. If the government provides the necessary environment near the containers, the recycling cycle is initiated.

Conclusion
It is a project in which we tried to improve something in various fields, with the sole aim of all involved in the process of housing construction to see that something better can occur with minimal extra effort. Houses are simple, easy to use, that optimize space and related internal and external. The developer has made an effort to improve construction quality and facilities. The builder was able to work on a construction site clean and fast execution and has the contractual obligation to maintain the treatment plant and solar energy for a year. This makes it possible to collect useful data for future promotions. And the user will have a house to live actively and use their services.
