Dawnus recently launched the innovative and sustainable model for the delivery of Passivhaus schools; Patrwm 21. The model offers a standardised approach to streamline school delivery in Wales, providing consistency in cost, quality and sustainability outcomes.
The Patrwm 21 model delivers a BIM ready, Passivhaus compliant, school solution that can be tailored to the individual needs of a brief. It provides local authorities across the UK outstanding whole life value through radically reduced construction, operational and maintenance costs; up to 80% less than standard building regulations. The rigorous fabric first approach of the Patrwm 21 model promotes healthy building environments for users, stable temperatures and excellent air quality. It maximises capital investment, while delivering consistently high quality and sustainable environments for pupils and teaching staff.
The model was launched and presented at the recently completed Ysgol Parc-y-Tywyn, one of two new Passivhaus schools delivered by Dawnus for Carmarthenshire County Council.
Patrwm 21 was developed by design and construction specialists Dawnus Construction, Architype and WSP. Specialists from each company were there to host and present at the event, which was attended by over 40 guests including representatives from local authorities across South Wales. The Patrwm 21 team presented an overview of the model, the benefits of Passivhaus and specific design and delivery outcomes achieved from the two schools delivered for Carmarthenshire County Council. This included the presentation of energy results from Ysgol Trimsaran, the first school we delivered which has been in use since September 2017. Energy bills at Ysgol Trimsaran demonstrated a 75% cost saving over the 8 month occupation period, compared to standard new build BREEAM Excellent rated schools.
The event was a success, with many requests from attendees for further information on the model, with follow up presentations arranged to demonstrate further details on cost certainty and energy savings.
With local authority clients continuing to recognise the cost, health and environmental benefits of the Patrwm 21 model, the consortium are currently working with Powys County Council in the design stage of three further Patrwm 21 schools including Ysgol Bro Hyddgen; the first Passivhaus accredited all-through school in the UK.
Matthew Morgan, Dawnus Director says: “We are very proud of the product that we have collaboratively developed with our partners, and the support of Carmarthenshire County Council. We look forward to improving our product, delivering social and economic benefit whilst providing better educational environments for our future generations.”
Sharon Owen, a teacher at Ysgol Trimsaran commented: “It is spacious, light and airy and has improved pupil’s pride and self-esteem…The temperature is constant so pupils don’t overheat thus improving concentration levels.”
