ASSESMENT OF ADDITIONAL SHADING DEVICES INSTALLED ON G40 PREFAB HOUSES IN TERMS OF INDOOR ENVIRONMENT

Popis výsledku v původním jazyce

Nearly a third of Prague residential fund is represented by prefab houses built in the second half of the 20th century. Indoor environment quality in those houses does not meet current standards in many cases. Refurbishments in the past were mainly focused on reducing thermal losses in winter with insufficient attention to air ventilation or summer overheating. The article deals with a significant problem of high indoor temperatures during summer period present in G40 prefab houses. It evaluates an influence of several types of shading devices on indoor temperature of selected representative room with regard to daylight quality and air ventilation. A number of existing G40 buildings was studied to set an appropriate theoretical model of representative room. Prevailing window orientation, glazing type and building surroundings were considered as well as room air exchange. Influences of several sun-shading devices were assessed using Dial+. External louvers have proven to have the greatest impact on reducing indoor temperature with providing enough daylight at the same time. Unsolved overheating not only has negative impact on residents’ health and mental wellbeing, it may often lead to usage of air conditioning. Air cooling is three times more energy demanding than air heating, therefore it is not suitable in terms of EU policy of reducing energy consumption.
