Passive Houses In Dublin
With increasing demand, passive houses are gaining ground and remodeling the infrastructure of many cities around the world. Ireland, for example, is a country that has been embracing this cause and increasingly choosing to build houses in this style. Whoever goes to Dublin find faces a lot of passive houses, and very close, in County Laoghaire-Rathdown County, the passive house standard is already mandatory in all constructions.
Experts ensure that the cost to build a passive home is the same or less than the cost of a conventional home.
But what, after all, is a passive house?
The passive house is a German certification model of sustainable construction, created with the goal of building homes and buildings with zero or very low energy consumption.
The name, passive house, is given by this being able to manage its acclimatization (capture, heating/cooling and distribution of air) by itself, with simple mechanisms and low energy consumption.
7 Basics For An Irish Passive House:
1- Super isolation: The passive house has high energy efficiency because it has thermal insulation much more effective than the isolation traditionally used in civil construction, avoiding or reducing the energy consumption for heating or cooling the house. The principle is that with an efficient thermal envelope, which is nothing more than its wrap (walls, roof, floors, and frames) well insulated from the outside, it creates a comfortable interior without resorting to the traditional systems of artificial acclimatization that consume lots of electricity.
2- Eliminate "thermal bridges": Thermal bridges are produced when the stability of the facade is weakened by the insertion of other planes or constructive elements (doors or windows). The passive house design should help eliminate thermal bridges and leaks from the cold or heat.
3- Planning and drawing: The part of the personalization of the design of an ecological house and the peculiarities of its owner in the passive house is also important to include in the project the possibility of acclimatisation the house with mechanical ventilation and make the most of the solar collector.
4- Dividers: Thermally, doors and windows are the weaknesses of a building because they are a source of heat loss or cold. The passive house standard suggests the installation of high-quality doors and windows with good thermal and acoustic insulation and double or triple glazing.
5 - Mechanical ventilation and heat recovery (for cold climates): Passive houses rely on heat recovery technology, an equipment that improves indoor air quality and allows the outside air to be heated by hot indoor air. This equipment fulfils two functions: to clean the air of the house with the air that comes from the outside and to allow that cold air to heat when mixing with the air existing in the house. This equipment does not consume energy since its operation is mechanical.
6- Heat optimization: In the passive house the heat generated inside the house by its inhabitants, light fixtures, and appliances is harnessed in the heating in the winter, In the summer there is a planning of sun protection. Using the principles of bioclimatic architecture.
7- The PHPP Software: Passivhaus concepts apply concretely through an Excel-based software called PassivHaus Plannig Package (PHPP) which adapts the thermal behaviour of the building to the thermal parameters of the passive house model.
Passive houses are undoubtedly the best solution for building a better planet, in addition to providing a great economy to users.
