VENTILATION
Adequate ventilation in a home is necessary to avoid condensation and mould growth. The information below outlines the work NEA does to improve ventilation, and therefore people’s health and general quality of life.
Passive Ventilation
This is what most people will have in their homes in some shape or form. For example, you will find airbricks and vents in walls to keep a property ventilated. It can also be important to ventilate a home properly to allow heating appliances to work correctly. Many homes will also have mechanical ventilation, for example, in the form of an extractor fan.
Positive Input Ventilation
As we have improved the energy efficiency of our properties we have reduced the amount of passive ventilation. For example, fitted carpets and insulated walls have created their own issues. Ventilation is a vital part of the solution to avoiding high humidity and condensation in properties. This can trigger the symptoms of asthma in some people.Positive input ventilation is a simple yet effective way of tackling this problem. A small specially designed box is placed in the loft. It will fit through the standard loft hatch which is helpful! It collects this warmer air and filters it before introducing into the whole house. This clean, warm air will replace moist air and create a pleasant indoor environment. This means that everyone can breathe easier.
NEA has worked with two systems: one provides ventilation only and the other includes a small heat pump which helps bring affordable warmth as well as cleaner air.
The small ceiling vent placed in the living room.
The second is a particularly interesting system. It is mounted in the loft, with a small, unobtrusive vent in the main rooms. There are also easy-to-use controls so the householder can dictate the speed and heat of the air flow. For more information on our positive input ventilation project, please click here.
