The Energy Village

the concept addresses two major Saudi Arabian government’s concerns: energy production and housing.
In this project the two is- sues are closely related to each other as this new concept aims to provide Saudi Arabia, a high quality, highly technological house built to produce electrical energy in excess to its needs.This allows the ow- ner to have the tools to either sell the energy, effectively making money while living the house or to use the production power to obtain bank loans. in any case, the actual price paid for the house by the owner is diminished drastically

The population of Saudi Arabia has grown very rapidly since 1970 and although from 2003 the trend has dropped,it still shows a steady 1,54%. To- day the kingdom is experiencing a shortage of affordable housing. The government has provided financial help but, despite these efforts, hou- sing prices have continued to increase. The expected growth of population and household units in the next 20 years added to the present shortage will generate a major gap between demand and supply.en demand and supply.

The ability to satisfy housing needs depends on resources. People with high incomes are likely to enjoy the most free- dom in choosing where to live, as are those with high levels of education. Family size, age, income, dependence on public transportation, and quality of neighborhood all has a bearing on location deci- sions. In addition, individual choice might affect location decisions for homeownership.

even though household residential locations within urban areas are very important, it is unlikely that housing market in metropolitan areas could satisfy the needs of all individual households. moreover, economic, social and physical factors in housing demand such as living space and a better living environment contributes to changes in lifestyle. Housing types should meet the need for housing within a growing urban market at particular price ran- ges and provide the necessary housing types for households at a wide income levels.

Saudi Arabia plans to bu- ild 1.65 Million new houses in the next 6 years, resulting in state investments of 276 billion US Dollar in the construction sector. These figures are unprecedented in the history of Saudi Arabia.
Today, Saudi Arabia accounts for 5.13 global hectares of ecological footprint per person, or roughly twice the world average, puts it at top 25 most environmentally challenged countries in the world. Sau- di interest is to support sustainable construction and energy efficient technology. It is only a matter of time before green guidelines become mandatory.

The energy consumption of Saudi Arabia rises by 9 percent per year. The use of air conditioning in sum- mertime alone currently causes a consumption of 3 gigawatts per year, while the annual energy consumption lies at about 30 gigawatts. In 2020, energy consumption is expected to reach between 60 and 70 gigawatts unless efforts are spent on developing a feasible energy concept that aims to use energy more efficiently. Without any doubt, this scenario would turn out to be extremely costly for Saudi Arabia.

While Saudi Arabia meets almost 60% of its domestic power needs from petroleum. this usage, which reaches 1 million bbl/d during summer months, and is on a pace to reach over 8 million bbl/d (oil equivalent)by 2030 cuts deeply into exports. The Saudi Government heavily subsidizes domestically used oil, which causes not only reduced export income, but also has enormous opportunity costs as there is less feedstock for development of downstream petrochemical industries and the jobs that go with them.

Saudi Arabia hopes to reduce by half the crude oil and natural gas it burns now to generate electricity, in part by developing solar power capacity, and is expected to introduce a National Renewable Energy Law this autumn 2012,
As part of its plan for reducing fossil fuel dependence, the Saudi Government aims to install 5 GW of solar power by 2020
The house is a two stories building with a foot of approximately 100 square meters and a net surface of around 170 sqmt. It comprise four bedrooms, three bathrooms, a spacious living room and kitchen, its own private garden, all surrounded by a design privacy wall.
The structure of the house, perfectly modular, is composed of a building envelope consisting of load bearing elements in fiber resin reinforced with carbon, between which is interposed a layer of insulating natural, closed on the inside with sheets of plasterboard. the outer wall is insulated with a film technique which is countered by a ventilated façade made ​​up of panels of porcelain stoneware. This composition was designed to guarantee a high insulation allowing the house to consume a minimum energy for the maintenance of optimal conditions inside.
The roof of the house, built with the same stratigraphy of the walls it is composed by a structure on which is installed an array of photovoltaic panels with high efficiency and capable of simultaneously producing electricity and hot water, part of which, is directly used on-site from the house. In the design process,we have implemented cutting-edge technical systems for space cooling and to minimize the consumption of electricity for the benefit of the production of energy from the photovoltaic roof.
The house is to be considered a PEB house ( PositiveEnergyBuilding) as it produces much more energy than it consumes.t
The house is infect able to produce annually 32.6 KW / hour of electric power and the 35,0 KW calorific that, in addition to making each home self-sufficient from the point of view of electrical and thermal, are capable of providing excess power to the electrical national grid, giving the investor an immediate economic advantage, and to thermal storage systems that are used as energy source at night, when electricity production is zero.

The energy village is an agglomerate of several pre-cast houses that share the same principle. providing high end housing solutions and produce electrical energy and hot water for both each house’s internal needs and for the supply of the excess energy to the electrical grid.
This project comes within a framework that could be implemented on the basis of “Build, and Operate” ; the investors will provide the housing systems, and in exchange they will be entitled to operate the power plant that the agglomerate will eventually form.
an agglomerate of 200 energy houses, will produce annually 6.580.000 KW/hour ( 6,58 MW/hour) of electrical power, the equivalent of the annual production of three medium sized power plant or 7,6 time as much as the newly inaugurated first solar power station on Farasan Island that is capable to produce 864,000 kilowatts
The energy so produced can be used for multiple purposes, last but not list, the desalinization of sea water.
