Building-block bits and bytes

Xella Polska and Multimedia Communication have launched two computer programs designed to assist architects and engineers in calculating construction specifications for Xella's Silka E and Ytong blocks, which are used mainly in residential construction.

The programs provide an algorithm-based model that instantly determines the feasibility of using either Silka E or Ytong blocks for construction projects, according to the project's dimensions and its environment.

"The programs allow for the accurate calculation of design specifications and substantially cut the time spent on documenting each individual design possibility," said Robert Kocwa, a civil engineer and a consultant for the program's design.

One of the programs is a durability calculator, which provides an analysis of materials and project conditions and thus defines a model for a building's construction. In addition, it calculates load-bearing capabilities for a range of technical and environmental conditions, including snow and wind.

The second program considers a number of variables, including climate-based, seasonal, temperature and ventilation factors, in order to establish a projected balance of insulation and humidity.

The program also addresses mold and condensation factors and provides solutions for correcting the balance across an annual range of conditions.

The programs are based on specifications set by the Building Research Institute.
