Did you Did you know?know?

That 1 in 5 properties in the UK suffer from condensation & mould..

…that’s over 5 million households!

But Why?But Why?

What energy What energy saving saving measures have measures have we introduced we introduced into our into our houses?houses?•Loft Insulation•Cavity Wall Insulation•Floor Insulation•Draft Proofing•Double Glazing•Central Heating•Sealed airbricks..

We’ve sealed up our houses to keep the energy in... but also the moisture and other contaminants..

In a property of 4 people, each person will contribute 4 pints of moisture per day, that’s over 100 pints of water vapour per week. This is a huge amount of moisture which must go somewhere... When you add in the other airborne contaminants which exist in a typical home

– it’s not difficult to understand the scale of the problem!

So what moisture is So what moisture is generated within a generated within a house?house?

What else What else is present is present in the air in the air within our within our houses?houses?

• Mould Spores• Dust Mites• Tobacco Smoke• Radon• VOC’s• Carbon Monoxide• Odours

So why have So why have extract fans extract fans failed to failed to provide the provide the answer? answer?

15 l/sec

30 l/sec or

60 l/sec

600 l/s

Traditional Intermittent Extract Fans extract at a rate of:•Bathrooms – 15 l/s•Kitchens – 30 l/sec or 60 l/sBut by simply opening a door the airflow can be as great at 600 l/s….so the damp moist air will migrate to colder parts of the house, and condense on walls and windows – leading to mould.

The Effect of The Effect of Temperature on Temperature on Humidity LevelsHumidity Levels

As temperature levels drop during the night the humidity levels increase proportionally. For every 1°C fall in temperature there is approximately a 5% increase in relative humidity – and reverse is

true as the temperature increases.

The solution is The solution is Positive Input Positive Input Ventilation... Ventilation... The EnviroVent Positive Input Ventilation (PIV) units are sophisticated whole home ventilation and condensation control units.

By drawing in fresh, filtered and clean air from outside, the units gently ventilate the home from a central position on a landing in a house or the central hallway in a flat or bungalow.

The solution is The solution is Positive Input Positive Input Ventilation... Ventilation... Moisture laden air is diluted, displaced and replaced to control humidity levels around 55% RH – significantly reducing surface condensation, the main cause of mould.

And with lower humidity levels, dust mite populations are also substantially reduced to provide a significant improvement in the health of asthma sufferers and general indoor air quality.

The The process process explained..explained..Shortly after Installation…

The unit gently ventilates the home with fresh air. Air is pushed back down into the house and is redistributed.

Humidity is replaced and diluted to leave a healthy, fresh and clean environment to live in.

Housing Health & Housing Health & Safety Rating Safety Rating Scheme?Scheme?

Are you worried about the HHSRS?The HHSRS is a risk assessment tool

used to assess potential risks to the health and safety of occupants in residential properties in England and Wales and came into effect in 2006

This assessment method focuses on the hazards that are present in housing. Tackling these hazards will make housing healthier and safer to live in.

It’s aimed at private landlords, to help them understand the requirements under the Housing Act 2004 and help them identify the type of work that is needed on their properties to conform with the HHSRS.

Damp and Mould Growth is a Category A Hazard – due to the possible physical and mental health effects from these hazards which include breathing difficulties, depression and anxiety, asthma, rhinitis, fungal infection.

And as we know increase in house dust mites and mould growth is directly linked to dampness caused by reduced ventilation levels, increased humidity and warmer indoor air temperatures in winter due to dwelling design.

Preventive measures include ensuring an adequate level of ventilation to cope with moisture from normal domestic activities without the need to open windows (that could lead to heat loss, noise and security risks),
