Tilatarpeet

Tilatarpeet is a Finnish term that translates roughly to space requirements in English. It refers to the amount and type of space needed to carry out a set of activities, including the layout, functional zoning, and auxiliary areas suitable for a given operation. Tilatarpeet is used in facility planning, architecture, logistics, and urban planning to guide design, real estate procurement, and future expansion decisions. It encompasses floor area, volume, and the allocation of space into functional zones such as storage, work areas, offices, circulation, and service spaces. The concept helps compare different design options and ensures that a building or site can accommodate current and anticipated needs.

Determining tilatarpeet involves analyzing processes, flows, equipment, personnel, and inventories. Common methods include process mapping, time–motion studies, capacity analysis, benchmarking, and simulation to model how space is used and how it might be optimized. Tilatarpeet is influenced by regulatory constraints, safety and accessibility requirements, energy efficiency, and plans for growth or flexibility. It is often expressed as concrete targets in square meters or as a space program (tilasohjelma) that assigns specific totals to different functions.

Examples of tilatarpeet vary by sector. An office building might allocate space for workstations, meeting rooms, and shared facilities, while a warehouse would specify storage racks, picking aisles, packing areas, and loading docks. In project planning, tilatarpeet informs architectural design, equipment selection, and budget, and is routinely revisited as operations evolve.
