Abstract

This research deals with the economic aspects of service systems in residential high rise buildings. It focuses on the estimation of life cycle costs of building’s systems.  The main aim of the study was to investigate the dependence of costs on building height and number of dwellings per floor, which is representative of the floor area. The cost variation was studied for a group of 10 to 40 story buildings and compared to the lower buildings in the 5-9 story range.

The service systems that were analyzed are: water supply and plumbing, elevator, HVAC, and fire safety.

Each system was studied in all its aspects: major role and performance requirements, operating principle, main components, requirements of the building codes and design basics. Subsequently, each system was investigated by implementing design fundamentals from literature. Discussions with various local engineers were organized in order to better understand the current situation in Israel.

Three square-type building layout models were developed, with 4, 6 and 10 dwellings per floor.  Detailed design of each system for the various model buildings was performed and followed by a calculation of its life cycle cost, LCC. The LCC includes initial, operating, and maintenance costs. Analysis of results focused on understanding the various cost variations versus building height and number of dwellings per floor for each system separately, and for all systems combined.
