Greenwood SMART Technology

How SMART can ventilation be?

How SMART can ventilation be? We take out noise, unnecessary running and unnecessary energy usage, amongst other things, so that we offer simple solutions that provide optimal performance in homes.


SMART Technology in practise...

SMART Technology comes in sensors, controls and design features within our products, usually our GIP product range.

The very first SMART Technology launched was Greenwood CommissionSMART™ Technology on our iconic Unity CV2GIP product.

The first of its kind - the SMART touch-pad was designed to improve and simplify the process of set-up and commissioning onsite. With all of the relevant and required features located in one place, the SMART touch-pad is easily accessible on the front of the fan; making is easy once it has been wired and installed in the wall or ceiling.

The second introduction of SMART Technology was Greenwood HumidiSMART™ which has taken humidity controlled ventilation by storm - now available in Unity CV2GIP, Omnique, Samika, Vireo MVHR and Centair CMEV.4e.

Humidity controlled ventilation uses humidity levels sensed in a room to boost ventilation - either turning it on or moving from a trickle speed to a boost speed. Why?? Because humidity means moisture which in turn needs to be extracted. Failure to provide effective ventilation causes mould, condensation and damp.

Greenwood HumidiSMART™ provides humidity controlled ventilation without nuisance running (in the middle of the night!), unnecessary heat loss and energy consumption from homes. It activates ventilation in response to man-made spikes in humidity only because it works with the 'real time' installed environment and knows exactly what the normal level of humidity is at any given point in time. It then uses this as its base line to look for spikes.

Traditional humidity sensors usually provide ventilation when it is needed, but it is often when it isn’t needed that the fan still comes on... WHY???? Because it uses a generic base line to activate the fan e.g. 65%. If it happens to be a hot summer's evening and the windows are open in the bathroom, this will activate the fan therefore causing nuisance running and unnecessary energy consumption!


The third SMART technology in practise is Greenwood CommissionSMART™ designed into Vireo, a brand new range of heat recovery ventilation units that offer the easiest and fastest commissioning process ever!


Greenwood HumidiSMART™

Humidity controlled ventilation which can't be adjusted and that works with the installed environment.

A new and revolutionary way of monitoring humidity levels to provide effective ventilation in domestic properties all year round.

Greenwood HumidiSMART™ is a patented technology designed to respond only to man-made humidity spikes caused by showers, baths and cooking. It ensures that ventilation is delivered when it is needed and not due to naturally occurring rises in levels of background humidity (like a humid summer's evening!)

It has been designed:

  • To remove nuisance running (especially in the middle of the night!!!)

  • To eliminate unnecessary heat loss caused by activating the fan when it isn't needed

  • To provide the correct level of ventilation for the property and therefore optimal energy consumption

  • So that it can't be adjusted by installers or end users and, therefore, protects the property all year round


Greenwood TimerSMART™

In the bathroom for 5 mins...overrun for 5 mins...a timer extract fan that works to minimise noise!

A new and logical approach to timer operation used in domestic ventilation fans and whole house systems.

It has been designed to automatically adjust the running time of the fan depending on room occupancy time rather than working on a pre-set runtime period e.g. in the bathroom for 10 mins, overrun for 10 mins - rather than having a generic 15min overrun timer.

It has been designed to;

  • Optimise energy usage once installed

  • Provide the appropriate levels of ventilation - no under or over ventilating the room unnecessarily

  • Eliminate unnecessary heat loss

  • Eliminate nuisance night time running


Greenwood CommissionSMART™

innovative design controls and features on Greenwood products that are simply there to make on-site set-up and commissioning the easiest it can be.

Greenwood CommissionSMART™ technology supports the installer on-site by providing controls that allow the accurate and simple commissioning of a ventilation unit or system. Using innovative SMART touch pads, wireless connectivity and set-up wizards, the process (as far as possible) is automated, increasing the speed and ease of achieving Guaranteed Installed Performance and reducing risk of non-compliance on-site.


Greenwood SummerSMART™

Imagine a whole summer without filtered incoming air - unlike others, our MVHR range filters the air even when the summer by-pass mode is activated.

This innovative technology ensures a home is comfortable 365 days a year, especially in warmer summer months, and is available only on a selection of models in our Heat Recovery range. By activating a summer by-pass mode, the Heat Recovery Unit continues to provide whole house ventilation but without the heat recovery element to prevent over-heating in homes.

*47 days based on temperature readings 


Greenwood WinterSMART™

No matter what how cold the temperature gets outside, your ventilation system will still be protected and provide you with comfort throughout the winter months.

This label ensures you will have a comfortable balanced indoor environment 365 days a year. Available on Vireo models in our heat recovery range.


Greenwood CarbonSMART™

All Greenwood CarbonSMART™ products can demonstrate tangible savings in running costs and energy usage when compared against their standard alternatives.

Our products such as the Vireo range, Omnique, Unity, Samika and MEV are CarbonSMART as they utilise the most efficient design, balancing watts and airflow performance in the most effective way. Our products are manufactured using very low energy consuming components.
