air conditioning & ventilation 39
natural ventilation means pollutants and mois- ture from everyday activities like cooking and bathing remain in the home. Moving indoor air quality up the agenda has
begun and this report from the Royal College of Physicians and Royal College of Paediatrics and Child Health has significantly helped the process of highlighting it. The important thing now is to continue the pressure and raise the profile of the significance of clean air. This is something manufacturers have been doing for some time, but as architects, developers and housing associ- ations begin to understand how the ventilation systems they specify impact on the health of their residents, there is an opportunity to use good ventilation as a strong selling point. In addition, like all things, once politicians recognise that poor air quality has an impact on the healthcare costs of a nation, the incentive to legislate
“As houses are becoming more airtight through efficiency measures, a lack of natural ventilation means pollutants and moisture from everyday activities like cooking and bathing remain in the home”
big benefit of BIM is that all those interacting with a building can optimise their actions, with entire teams working to the same standards to produce the best possible project outcomes. BIM brings together all the components for a building so that different aspects of the design can be integrated more effectively. The BIM objects website (
bimobject.com)
contains freely downloadable information about the product including for example (for ventila- tion systems) performance, specific fan power, visualisation and functional data.

rises. With the hope of new legislation and advancing technologies, indoor air quality has a positive future.
Building Information Modelling (BIM)
On an entirely separate note, there has been technological advances in the way that ventila- tion systems are being specified, as Building Information Modelling (BIM) is used more widely. Architects and specifiers have begun to see the benefit in timesaving and accuracy that it can offer for their plans and modelling. The
As far as legislation is concerned, the ErP Directive, setting minimum performance criteria for ventilation, became effective from 1 January 2016, so all ventilation systems suppliers need to respond to these changes. The ErP Directive, which is European legislation, applies to products that can have an effect on energy consumption throughout their lifecycle, from manufacture, through use, and until the end of their life. With ventilation systems falling under this category, each product now has to carry an energy effi- ciency class rating which gives information about its energy efficiency of the product.
