Engineering for energy cost and emissions reduction
Passive Houses or Passive Buildings are highly energy efficient constructions.
Passive building engineering must be designed to reduce as much as possible the emissions generated in the construction and life of a building. The development of such a project involves a highly integrated and collaborative approach between engineers, architects and other building professionals. In engineering a passive building to reduce energy costs and carbon footprint, several cross-cutting factors must be taken into account:
Location:
The climatic and geographic conditions of the site are analyzed, including sun exposure and wind direction. The orientation is optimized to maximize sunlight in winter and minimize it in summer, reducing the need for heating and cooling. The use of natural light and ventilation is prioritized.
2. Isolation system:
It works to minimize the transfer of heat or cold and ensure a comfortable and healthy indoor environment. Therefore, choosing the right materials is a fundamental step. Triple-glazed windows and insulating frames are preferred.
3. Design of customized ventilation and heating systems:
Our engineering team utilizes a combination of technologies and design strategies to minimize energy demand for heating, cooling and ventilation. In addition, we always have a mechanical ventilation system with heat recovery, which maintains a constant flow of fresh air without losing thermal energy, and a high efficiency heating system, which may include a heat pump or underfloor heating.
4. Simulation and performance analysis:
We also put our design to the test by means of a software energy and climate simulation to predict the building's energy performance and thermal behavior under different climatic conditions. All this to ensure that we meet preset performance standards.
As you can see, passive building engineering is designed to reduce emissions as much as possible during the construction phase and also throughout the life of the building. In this video you can see one of the works we have carried out together with Marès for BigMat VergerThey have wanted to make their work hall as environmentally friendly as possible.
