研究目的
To examine the impact of loggia extension on the apartments’ interior lighting conditions and to determine the limit width of the loggia, which does not prevent the fulfilment of the requirements for insolation and daylighting of residential buildings.
研究成果
Leaving the original layout of apartments does not allow extension of the loggia while complying with the requirements of the Czech legislation on daylighting in residential buildings. Modifying the layout by removing the partition between the kitchen and the living room and replacing the opaque part of the window with clear glazing allows the loggia to be expanded by 900 mm without compromising the requirements for daylighting and insolation of residential buildings. This expansion leads to a significant improvement in the user comfort of the apartment.
研究不足
The study is based on a specific example of an apartment house in Prague, built in the standard system VVU ETA, located in practically ideal conditions. The results may not be directly applicable to buildings in different conditions or with different construction systems.
1：Experimental Design and Method Selection:
The study examines the possibilities of loggia extension on a specific example of an apartment house in Prague, built in the standard system VVU ETA. The building is located in practically ideal conditions, with a southern orientation of the loggias and without any shading obstacles.
2：Sample Selection and Data Sources:
A panel house built at the Prague housing estate of ?epy was chosen as a model example.
3：List of Experimental Equipment and Materials:
The study considers the addition of a thermal insulation of 150 mm thickness on the facade and the use of plastic euro-windows double-glazed with clear glass.
4：Experimental Procedures and Operational Workflow:
For both variants (with and without a partition between the living room and the kitchen), calculation of insolation and daylight is performed according to valid Czech legislation, for various loggia widths ranging from 200 mm to 1600 mm at intervals of 100 mm.
5：Data Analysis Methods:
The sunlight duration was calculated using the Světlo+ software, and the daylight calculations were performed in the software environment Building design using the computing module Wdls 5.0 – Daylight calculation.
