Which career path should you choose? Architecture and Interior Design have a lot in common, but which one is right for you?
By Doug Major 02 Feb, 2024
As climate change becomes an increasing threat to our planet and homeowners face soaring energy costs, the ethos of the PassivHaus have never been more relevant. More of us than ever are looking to make our homes more environmentally friendly and simultaneously reduce our costs, which is why we are asked so many questions about how owning a PassivHaus can help. But what is a Passivhaus? and how does it differ from a conventional home? A PassivHaus is a building that provides a high level of occupant comfort using very little energy for heating and cooling, due to its energy efficiency and sophisticated design. According to the PassivHaus trust, buildings are accountable for 35% of total global energy consumption. So, by reducing energy loss in the home and reducing the need to rely on excessive heating and cooling mechanisms, it becomes a positive and essential step in the fight against climate change. Not to mention the advantages to PassivHaus owners. From extremely cheap energy bills to year-round temperature comfort and filtered air, the benefits are clear to see! As one of the UK’s leading PassivHaus design firms, we’re here to answer your top questions about living in a PassivHaus.
