Adults need space too, to foster healthy relationships with their partners and enable them to care for their families. Striking the Perfect Balance Much has changed since Neutra in terms of what we call a healthy home. Today we need different approaches: Careful placement of high quality windows that maximize view and light without risking overheating; High levels of insulation to keep warm or cool with a minimum of mechanical intervention; Mechanical heat exchange and ventilation system that provides controlled, filtered fresh air; Healthy materials that are easy to clean and do not emit VOCs; Resilient designs that can survive the increasingly common disruptions and changes in climate; Simple systems that occupants can actually understand and operate themselves: Where occupants have been presented with complicated heating, lighting or ventilation controls they may struggle to maintain internal temperatures, fresh air rates and appropriate light levels – all of which can have health impacts. The consequences of residents not feeling in control of their systems can lead to homes becoming too hot or too cold, reduced energy efficiency, and in some cases it can then lead to exacerbated levels of fuel poverty While this document has been written in the UK, most of its content is universal. One message that certainly travels well: A home is more than just a box to be bought and sold; it, and the community that it is part of, seriously affect our health, happiness and wellbeing.
