Ergohome Ventilation

Building regulations are more demanding

Domestic dwellings will have to be built to higher ventilation standards. Building regulations approved document Part F document describes four levels of building ventilation from the “basic” through to the “sophisticated”. In the past homes tended to have an extract fan in the bathroom and trickle ventilators above each window, these simple solutions alone are unlikely to meet the new requirements.

Build tight – ventilate right

This modern building mantra has environmental origins in Germany where the Passivhaus concept is established. Traditional UK site-building methods have not promoted air-tightness; often because dampness was always present due to poor detailing or workmanship thus it was necessary to “ventilate” a structure on a continual basis to stop damp rot. Downsides of this approach have been draught-ridden rooms, high-energy bills and in some cases rotten homes. The modern way to build homes is to keep the fabric airtight with designed ventilation.

Ergohome is built tight

Ergohome is designed to exceed future requirements. Ergohome achieves outstanding performance when compared to the regulation minimum, normal build standards and it is nearly twice as good as best practice. Results measured by independent experts BSRIA.

Air Permeability (m³/h.m² at 50Pa)

Regulations worst acceptable limit = 10.0

ATTMA Normal Performance = 5.0

ATTMA Best Practice = 3.0

Ergohome = 1.82

Ergohome incorporates whole house ventilation

Ergohome has also incorporated the most sophisticated level of ventilation commonly known as M.V.H.R.  A mechanical fan pressurises the whole house pumping fresh air into each room. As part of our hidden duct system waste air is passed across a heat exchanger transferring its warmth into the incoming fresh air (Heat Recovery). It is no longer necessary to open windows for the purpose of getting fresh air, a real benefit to those who suffer from; insects, pollen dust or road noise.

Ergohome has special MVHR

Ergohome ventilation has unique and special design features:

1) The supply fan uses the latest very low energy brushless DC motor. This means that necessary continuous running of the system is still affordable.

2) The supply fan is located outside the building to eliminate all fan noise from the ducting, a common complaint of other MVHR solutions.

3) We have a special waste air “convection chimney” that uses the warmth of the sun to further aid “drawing” of air through the system.
