Majorana plus energy house : preliminary plan

The 24 sqm plus energy house in our preliminary project has to be built in accordance with the ten bio-architectural points, listed in our previous presentation in Sneek.

10 RULES FOR A MODERN GREEN ARCHITECTURE

1. Build respecting the typical architecture of the territory 2. Take in account the exposure, orientation and natural

daylight3. Use Eco-friendly materials 4. Ensure Impermeability and breathability5. Ensure Thermal insulation 6. Low energy demand 7. Energetic autonomy8. Water autonomy9. An Autonomous system of household waste disposal10. Automation and comfort

The house is to be built in the Valle d’Itria, in a natural environment characterized by:

-Mediterranean climate with poor rain and summer dryness and average winter temperatures of 6 °C and summer temperatures of 23 °C .

Description of its environmental context

Fertile soil with almost emerging limestone rocks and caves, deprived in its surface of water courses, in a mainly hilly landscape

Description of its environmental context

Natural vegetation typical of the Mediterranean hillside such as  ‘fragni’( quercus trojana, ), oaks (quercus ilex)  olives, arbutus, cistus, mastic, myrtle, almonds, cherries, figs, vines, laurel, wild pear

Description of its environmental context Trees and bushes

Prevailing cultivation of vines, wheat, forage

Description of its environmental context Cultivations

A tourist area offering  cool and windy weather and  beautiful natural landscapes , it has got wonderful natural landscapes and is highly inhabited.

Description of its environmental context Weather and landscapes

- It is dynamic thanks to the presence of a large number of factories that operate mainly in textiles, construction, tourism and farming

- the nearby Taranto with its steel factory, one of the largest in the world, its naval bases and its largest seaport has contributed to the wealth of the local families.

Description of its environmental context The socio-economic situation

The house is a small summer house for two people with an internal surface of 24,00 sqm, divided in a multifunctional room, a small kitchen and a bathroom.

On the southern side there is a glass porch covered with solar panels. In the hot seasons,this will be covered with a natural shading system, made of typical local climbing plants with summer florescence . On the western and eastern sides there are two pergolas with vine plants which are widespread in our territory.

Glass porch and natural shading

The perimeter walls are made of 3 layers, in the middle there is a panel of cork and the external layers are made of local limestone extracted in quarries within a radius of 30 Km. These materials are eco-friendly and respect the old and traditional building techniques.

Perimeter walls

The roof has an internal calcarenite flat vault and it is insulated and waterproofed with cork panels.

The house will be provided with - a photovoltaic system fully integrated in the architecture, - a micro wind power system, - a thermal solar plant fully integrated in the porch and of a geothermic system with heat pumps.

Building Features Energy provision

Rainwater will be collected from the roof and treatment system for home usage will be provided as well as a sewage plant for the waste water.

Water provision

Every technological system will be controlled by a remote domotics system.The building details and the specific technological systems will be defined later with an executive project.

Estimate

Fundations structures € 3,500

Walls + stone vault € 8,000

Waterproofing € 2,500

Insulations € 2,500

Plasters + floor € 6,000

Veranda + pergola € 9,000

Doors + windows € 4,000

Rainwater tank + treatment plant € 7,000

Electrical+sewage+water system € 2,500

Air conditioning 1kW € 3,000

Photovoltaic system 3 kWp € 10,000

Wind power plant 1,5 kWp € 5,000

TOTAL COST € 63,000

Annual electrical energy producedEnergy produced by photovoltaic plant……... 3,300 kWhEnergy produced by aeolic plant…………...... 1,500 kWhTotal annual electrical Energy produced…… 4,800 kWh

Annual energy requirementHeating and cooling…….................................. 1,800 kWhHot water…………………….....................….... 700 kWhLightning…………………………………..…...... 200 kWhHousehold appliances………………………….. 500 kWhTotale energy requirement ……………………. 3,200 kWh

Energy Surplus 4,800 – 3,200 = + 1,600 kWh per year

Conclusions : The calculation of the total Energy requirements is the result of the effective annual consumptions of each plant:- for the air-conditioning considering a plant of 1kw access power per 2,000 hours a year ( 5hrs a day , all year) - for the heating of the water considering an electrical boiler of 1 kW access (2 hrs a day ,all year)- for the lightning a 100 bulb switched on 5 hrs a day.

Annual Energy balance

The preliminary design consists of the following:

a) Explanory report

b) Dimension plan

c) Equipped plan

d) Plan of the outside area of the house

e) N.1 tridimensional view of the house

f) Estimate of cost
