Build tight Ventilate right is often mentioned but not always adhered to. Not so with the exclusive Dooroge woods housing development in Dublin. The main contractors are Greyfields developments who have a history of high quality developments via Marhan construction.
Dooroge woods is a development of 37 luxury 3, 4 and 5 bedroom detached homes close to swords in Dublin. The aim of the developers was to deliver a high performance development that would deliver in terms of quality in all aspects, not just a A2 rated property.
Impressive airtightness was demanded and so Ramstown Timber frame were appointed together with the Ampack Airtightness range. Nicky Stafford of Ramstown timber frame is experienced in passive house building and airtightness and was an interesting choice have worked in ‘one off’ housing most recently.
The quality control procedure from passive house single dwellings is welcomed in multi-unit development and has seen the development meet or exceed the brief where airtightness is considered.
Greyfield developments as modern developers are acutely aware of the air quality issues and are keen to continue to develop a long term reputation for high standards.
Accordingly we were brought in to present LUNOS decentralised ventilation systems. The issue of quality control with ducting installation and future cleaning was a factor when LUNOS were appointed. 
The chosen LUNOS demand controlled ventilation system (DCMEV) operate on a completely decentralised system – Ducting is right through the wall via pressure controlled inlets and intelligent extracts that adjust automatically relative to time temperature and humidity. LUNOS fans have expected lifespans of over 30 years and can cost €5.00 per year to run for the overall system. With this system indoor air quality is assured for decades.
