Zyle Fenster Supply 200 Aluminium Clad Windows To Passivhaus Extra Care Project.

Zyle Fenster and EcoWin Ltd have been awarded the contract to supply over 200 Aluminium Clad Passivhaus windows and doors for an exciting and forward-thinking Passivhaus extra care project in Exeter. This is another Passivhaus project for Zyle Fenster and we are delighted to be helping the elderly and infirm to move to more comfortable, safer, and affordable accommodation.

St. Loyes Extra Care Home Scheme

The St. Loyes Extra Care Home scheme forms part of the Millbrook Care Village development commissioned by Exeter City Council. As well as using high quality materials to create a low energy and healthy building design, the aims of this project are to incorporate the latest thinking on elderly and dementia care and to achieve a homely, non-institutional and secure feel to the new building.

The architects, Architype, discounted the typical institutional care home layout of long central access corridors with rooms located on either side. Using Integrated Environmental Solutions thermal modelling and Passivhaus planning analysis, their radical design not only addresses the monthly heating and cooling demands but also creates a healthier and more comfortable environment with an improved ventilation strategy.

Their scheme consists of 50 self-contained units for the elderly and people with differing levels of dementia. It also incorporates a high level dementia care facility.
Older residents will retain their independence as well as remain firmly connected to their local community and the building includes lounges, dining rooms with roof terraces, hobby spaces, salon and spa treatment rooms and landscaped gardens.

Climate Change Forecasts Make Passivhaus More Important

As the residents will be elderly and frail, it is essential that this Passivhaus development offers appropriate levels of thermal comfort and maintains appropriate temperature and humidity levels throughout the year. With increased temperature rises and adverse future weather conditions forecast from climate change, the building needs to be future-proofed to minimise the effects of daily and seasonal temperature fluctuations. This project has received additional funding for design work from the UK Government through the Technology Strategy Board’s Climate Change Adaptation programme.

The main climate risks that the project is aiming to address are increased and unstable external temperatures and humidity levels that could adversely affect the internal environment. An increase in wind and rain severity and seasonal fluctuations may cause water shortages, disruption to the landscape and flooding. Finally, with less wind and higher external temperatures, airborne particulates, manmade pollutants, and an increased pollen count may also reduce external air quality.

Zyle Fenster and Ecowin Passivhaus St LoyesA Passivhaus building allows for space heating and cooling-related energy savings of over 75% compared to average new builds. It makes efficient use of the sun, internal heat sources and heat recovery and uses passive cooling techniques such as strategic shading to keep the building cool. Internal surface temperatures will vary little from indoor air temperatures, even in the face of extreme outdoor temperatures. Passivhaus windows help to create a seamless building envelope with the highly insulated roof, highly insulated exterior walls and floor slab maintaining internal temperatures. A Passivhaus ventilation system supplies constant fresh air whilst the heat recovery unit allows for the heat contained in the expelled air to be re-used.
