The construction industry is one of the main sources of greenhouse gas emissions given the wide cycle of polluting activities it involves, from the extraction of aggregates to the transport of materials and their production. For this reason, and also to reduce costs, many citizens, prefabricated houses. Not only are they cheaper, they also have less environmental impact. But there are some things you should know.

A ecological prefab house It is a house that is manufactured in a workshop or warehouse and assembled on-site, but is completely prefabricated.

Instead, a ecological modular house It also consists of modules that are produced in a workshop, but then transported in parts and assembled in the target plot, according to the special portal Ecocosas.

So although there are very similar forms of construction, since both are designed and largely built in a different location than the final land.

It is important to consider one aspect: Although there are removable, portable and prefabricated houses, they need a building permit just like it’s made of brick, because this is determined by municipal urban regulations throughout Spain. Therefore, the construction of one of these houses without a license from the City Council can be considered as a violation that will require a heavy fine for the landlord as well as the removal of the house.

HoweverWhat requirements must these homes have for them to be considered ecological?? Obviously, any type of removable enclosure is not sufficient, they must meet a number of conditions.

sustainable materials

Modular and prefabricated houses will be considered “green” should be built with environmentally friendly materials. This means it has a low environmental impact, the materials are from sustainable sources, and the fit with the land is harmonious.

For example, fiber-drywall panels from which some prefabricated house models are made are certified as ecological, while adhesives and other materials that cannot be accepted as such are used in plasterboard panels.

In the case of houses made from shipping containers for example, the ecological factor will focus on the fact that it is recycled industrial sea waste and can therefore be considered a sustainable material.

There are also modular wooden houses built with wood from sustainable sources, certified and having a low environmental impact.

Energy efficient and self-sufficient

Another important factor is energy efficiencyIt is necessary for a house to be ecological. The use of different insulation techniques, such as the location of the house to obtain more solar energy and the use of air to generate energy, as in aerothermal energy, which provides heating or cooling of the environment and heating of water.

In addition, use solar panels to heat the lights, electricity and water tankAmong other things, prefabricated or modular homes pride themselves on being energy efficient and therefore more ecological.

Self-contained eco-homes take advantage of the sun’s orientation, rainwater through tanksenergy expenditure with insulation of walls and windows, among other things, insulation of pipes, tanks, floors and ceilings, and improves the relationship with cold, heat and humidity.

Passive Prefabricated Houses

Prefabricated passive houses are the houses that make the most of energy. What distinguishes a passive house from a traditional building is this: heating and electricity used for household appliances should not exceed 15 kWh and 20 kWh per square meter per year, and the need to heat the house is less than 10% of the total annual working hours.

These figures are far below Turkey. a traditional build that spends about 900% more.

The advantages of this type of housing, which makes the most of ventilation and settlement, better preserves the interior temperature thanks to its materials and insulationThanks to the ventilation system that balances the temperature/humidity ratio, it is less humid, provides much healthier air, and provides great energy and economic resource savings.

Although this type of housing is more expensive to build, it is more profitable in the long run due to the economic savings that come with energy savings. It is also more environmentally friendly and emits less CO2.

And prices?

There is a lot of variety, but you can always find models suitable for hosting a family, ranging from 30,000 to 120,000 Euros, in the catalogs of companies in the sector. The average price of a 100 square meter house can be around 70,000 Euros., according to inarquia.es. What these amounts include, possible extras that may arise later, building permit procedures, etc. Knowledge of the subject is recommended.

These are some of the completely ecological modular house models highlighted by another exclusive portal. inarquia.es:

Brutalist Model Ecological House

The first option is a brutalist style house, a type of architecture inspired by Swiss architecture that developed between the 1950s and 1970s.

Created by the Goncesco Group and James & Mau, a company specializing in architectural and eco-efficient modular construction, these homes respect the environment as they are built with green materials and super eco-insulation.

As for its architecture, it is bioclimatic and powered by renewable energy sources.

Satori Model Ecological House

They are trying to create 90% recyclable houses from Alucasa while respecting the comfort and equipment of the whole house. Insulation is fully embedded to reduce energy consumption.

The constant maintenance of this model, whose manufacturing and delivery time ranges from 40 to 60 days, means that in addition to material quality, malfunctions are minimal and energy efficiency bears fruit.

Ecological House Model Lindal Cedar Houses

Design and respect for the environment come together to create gorgeous homes, and one of them is the model created by Lindal Cedar Homes.

Health-friendly LED bulbs, large windows and glazed panels receive more of a return from the sunlight that warms the home. It also has ceilings with white foam panels that help regulate the temperature.

They created an autonomous well with a capacity of 9,000 liters, which is not only electrically efficient, but also considering the source of the water.

Ecological house Gran Villa de Eurocasas

Prefab home manufacturing company Eurocasas has been building homes for over 30 years. They create a house with reduced and efficient consumption by using efficient materials, insulating windows and LED lighting throughout the house, with aesthetics suitable for every space.

La Gran Villa, the modular house with the lowest energy consumption in the industry, makes it an option you should consider if your goal is to live in a completely ecological house.

Ecological House Basic Model

The basic modules are the ideal complement to any house or plot. They can be a guest space or a private ecological prefabricated mini-house. It is also easy to assemble, and also pleasant and ecological.
