Moisture and breathability – the key to building performance and healthy buildings - Bristol
Buildings should be considered not as standalone discrete entities, but as part of a system in constant and dynamic interaction with people and the environment. This interconnectedness means benefits, problems, solutions and consequences cannot be effectively addressed in isolation.
As we build ever more air tight buildings and refurbish existing ones, often with energy efficiency as the main driver, the case for delivering effective moisture control becomes ever more paramount. This must be alongside good detailing, quality installation and an effective ventilation strategy.
Consideration of product impacts should be an essential component for sustainable and healthy buildings and NOT an afterthought. With staff costs amounting to 90% of most office based business operating costs and because we spend so much time indoors, it is essential that the industry delivers healthy buildings. This is especially important for vulnerable groups such as children and the elderly; so buildings such as schools, housing and medical centres.
The task of retrofitting our entire building stock to enable zero carbon buildings by 2050 is a daunting one, which requires an estimated 781,250 homes to be refurbished every year – or 1.5 homes a minute. There is emerging evidence highlighted by Peter Rickaby at STBA/SPAB conference June 13th 2017, that some homes that have been retrofitted to such a poor standard, that they have been wrecked.
Most buildings built roughly before the first half of last century are vapour open and inappropriate materials applied in a retro-fit may prevent the passage of moisture through the building. However the concept of breathability and moisture control is poorly understood. This seminar brings together leading practioners, academics and suppliers to share their knowledge and learning.
There will be drinks from 17:00, so please join us.
