  What is the energy efficiency of the Cyprus Passive House? The energy savings in the Cyprus Passive House (Passivhaus) reach 75% compared to low energy houses. Low energy houses are considered buildings that have Energy Performance Certificate indicating energy index “A”.   How efficient are the buildings in Cyprus The energy efficiency requirement for the buildings in Cyprus was introduced in 2010. This requirement is only followed for new constructions. Most new constructions have a certificate for energy index “B”. That means they are much less energy efficient than low energy houses with index “A”. Compared to the energy demands of the buildings constructed in Cyprus…

In Cyprus the sand dust in the atmosphere is a frequent phenomenon. It enters the buildings through the open windows and doors and settles on all surfaces inside, creating an atmosphere of low hygiene. If the humidity of the air is high the sand dust can condensate and get stuck to the surface it sits upon, causing damages. Living in a Passive House (Passivhaus) in Cyprus you don’t need to keep open any windows. Thanks to a carefully designed ventilation system with high quality filters no dust is coming in the Passive House from outside. The ventilation system is designed to…

In Cyprus the humidity of the air is often high. This contributes to the formation of mould inside the houses. High humidity combined with poor ventilation and the lack of proper thermal insulation creates perfect moist environment for growth of mould and bacteria. Thermal insulation of the buildings in Cyprus has never been a requirement before 2010. During the winter time the difference between the temperature of the air inside the house and the temperature of the internal surface of the external non insulated wall can become so big that water condensation can be observed. Water condensation and mould destroy…

The five basic principles of the Passive House (Passivhaus) are: Proper thermal insulation of the structure High quality windows Ventilation system with heat recovery Airtightness of the structure Lack of thermal bridges These principles were the result of decades of research done by The Passivhaus Institut in Darmstadt, Germany, led by Dr Wolfgang Feist. Building a Passive House in Cyprus provides perfect comfort and generates great energy savings.…
