Why Do We Ventilate?

Ventilation helps to promote a healthy, clean environment

Designed to remove stale odours & replace with fresh air

Prevent build up of excessive moisture & humidity

Removes excessive C0₂ generated by humans & pets

Lack of Ventilation - Effects

Condensation Mould Growth

Dust Mites / Allergies

Smells & Odours

Rn (222)

Radon

Radioactive, Colourless, Odourless gas. Rises from the ground Estimated 100,000 homes have a concentration above safe level 200Becquerel per m2.

How We Generate Moisture (BBCC)

Cooking

Cleaning

Bathing

Average person generates 4 pints of moisture per day

Breathing

Moisture:

Bathing, Breathing , Cooking & Cleaning generates moisture which is absorbed into the air (Like the tap running into the sponge)

Your Properties air will accept a certain amount of moisture and hold onto it without dripping

Once full the sponge leaks as it cannot hold anymore moisture (like in the air in your house)

Once the sponge is leaking moisture forms on your windows and walls as the air is now full and cannot accept any more

YOUR PROPERTIES AIR IS LIKE A SPONGE

How Do We Explain Moisture In The Home?

Condensation is caused when moisture held in the air meets a cold surface like a window or wall and condenses into water droplets.

When we Bathe, Breathe Cook & Clean we create moisture which results in condensation

It often results in black mould growth on walls and other surfaces or you can see actual water droplets. It is usually worse in corners, on or near windows, in or behind wardrobes and cupboards.

What Is Condensation:How Do We Explain Condensation In The Home?

Always Coca Cola!!!

CONDENSATION - THE MAIN CAUSE OF MOULD GROWTH

Moisture & Condensation:

Moisture created in the bathroom from showering

Once you open the door the moisture looks to escape to the coldest part of the house

Below shows the result of poor ventilation within your home

Further Issues: • Current Regulations & Standards drive buildings to save energy and

reduce gaps in properties – lower fuel bills & save money

Loft Insulation

Cavity Wall Insulation

Double Glazing

CondensationAll of the above measures reduce air leakage

The Solution

Positive Input Ventilation (PIV)

PIV - The History • Nuaire are the originators

of PIV Systems developed with North Eastern Gas Board

• Over ½ Million Nuaire PIV Systems installed in the UK

• Used by Local Authorities & Housing Associations all over the UK

• Independently Tested by independent bodies such as Napier University Report & Document IP/1200 by BRE

HHSRS - Category 1 Health Hazard!

MOULD GROWTH IS CATEGORY 1! (SERIOUS RISK) Local authorities are under a duty to take action

against category 1 hazards which include Damp and Mould Growth.

As Landlords you have a responsibility under the Housing Health and Safety Rating System (HHSRS) to assess hazards and risks within your rental properties.

Leaving mould present in property causes serious health issues, causing some tenants to successfully claim compensation from Landlords.

PIV - How It Works 1) Clean, fresh air is continuously drawn in to the loft space through the loft’s natural leakage points

3) The air is then passed through the filters, and is gently fed into the dwelling via a central hallway diffuser

2) The warm air then rises to the highest point, gaining heat energy giving you the benefit of some heat recovery

4) The air then gently pressurises the house from inside out, driving out the moisture and condensation

5) This process creates a clean, healthy environment to live in as fresh air replaces the stale air

Dilute – Displace – Replace

Moisture & Condensation With PIV:

Moisture created in the bathroom from showering

Once you open the door the moisture looks to escape to the coldest part of the house

Drimaster Diffuser is positioned in the hallway purposely to mix with the stale air

Dirty moisture laden air is diluted by the clean fresh filtered air from the Drimaster

Air escapes through the natural gaps in the property

When Are Additional Extract Fans/measures are Needed?

When there is an internal wet area WITHOUT an openable window.

When the air flow from the diffuser has to pass through two doors to reach a wet area.

When PIV is suitable on its own:

Wet rooms directly off the hall (all with openable windows)

When is PIV not suitable on its own:
