The Construction of the European House Concerning Ecological Needs and Sustainability

3rd Meeting ― 17th -21st October 2011 ― Bucharest

• Characteristics of a sustainable house.

• Building Systems.

• Use of renewable energies.

INTRODUCTION

What about a sustainable house?

Consists in satisfying the necessities of nowadays’ generation without sacrifying the capacity to fullfil future generations needs. (Informe Bruntland, ONU 1987).

What’s sustainability?

It is orientated and designed in order to get comfort with a minimum amount of energy spent.

Main design factors:

• Solar radiation

• Wind currents

• Vegetation around the house

Sustainable house: design factors

Sustainable architecture worries about the environmental impact:

1 – Construction techniques.

2 – Construction Placement.

3 – Environmental impact.

4 – Energy employed.

5 - Construction Materials.

Sustainable house: : environmental impact

1.-Ecosystem and situation

2.-Energetic systems taking renewable energies and into account.

3.-Construction materials

4.-Recycling and reusing materials

4 basic pillards

1-The building orientation is very important although most of the times it is not taken into account. A house cannot always be built where the owners would like to do it. There are not too many options as far as placement is concerned.

CHARACTERISTICS OF A SUSTAINABLE BUILDING

2- The heating system is very important since most of the times energy in a building is lost due to the materials used . In order to avoid this materials should take into account:

1 –Heat accumulation

2 –Windows and doors must be isolated.

A great efficiency can be acquired by using: - A good isolation system in roofs and walls. - Sun protection for windows. - A good system of ventilation - A great efficient conditioning air system.

Production of renewable energies for self use.

- Solar energy captation by means of photovoltaic cells.

- Installation of small size aerogenerators.

- Systems of solar heating

3.- CONSTRUCTION MATERIALS

The building of the house must take into account different aspects such as :

•Soil movements

•Structure and roof

• Impermeabilization

•Isolations

•Filling

•Glass and painting materials

•Electricity

4- RESIDUES AND REUSE:

IMPLIES:

- Treatment of grey waters

- Biologic stabilization

- Compostage production from organic garbage.

- Recycling.

Water efficiency:

Water resource is not illimited that is why its use should be reduced optimizing thus the circle of water use.

• Grey waters should be recycled for plant watering or water close use.

• Cleaning system of water should be included or even provide different water saving systems in the house taps.
