Experiences from New Swedish Passive House Projects

Ulla Janson

Abstract

ABSTRACT: In a Swedish research project carried out at Lund University, new Passive house projects are studied to see what knowledge and components that are necessary to get a more wide spread deployment of Passive houses in a cold climate. The Passive houses are closely followed; from the clients decision on building a Passive house, through the planning process, the building process, measurements of actual energy use after the tenants move in and the tenants ’ opinions on living in a Passive house. The results show a low need of energy for heating together with high indoor comfort. One investigated Passive house consumed 44 kWh/m2 per annum of district heating for heating and domestic hot water: a 72 % reduction comparison to Swedish averages 160 kWh/m2 per annum for heating and domestic hot water in multifamily houses. Knowledge among all building team participants about Passive houses is necessary to get a well functioning dwelling.
