High-Rise Building
Multi-unit residential building, typically in excess of 10 floors. There are generally four configurations for high-rise buildings:
  • Single high rise
  • Multiple high-rises (on a podium)
  • High rise combined with low-rise and townhouses
Some high-rise buildings have recreation facilities, such as a clubhouse and swimming pool.

High-rise buildings may be standalone or part of a larger facility.

The high-rise class of buildings have some unique attributes, including a larger number of assets, specialized safety assets such as emergency generators, and assets to move fluids longer distances such as booster pumps.



A.  Physical Analysis

Some of the more significant assets at a high-rise building, that differentiates this type of development, includes the following:
  • Booster pumps
  • Emergency generator
  • DDC
High-rise building have the following general physical attributes that impact maintenance requirements and lifecycle costs:

B. Financial Analysis

High-rise building have lifecycle cost patterns that differ slightly from low-rise buildings and townhouse complexes.


i)  Expenses



ii) Funding
While high-rise buildings have funding requirements for projects of greater absolute cost they can sometimes leverage economies of scale that offset these larger amounts to levels comparable with the other building classes.

Funding requirements for high-rise buildings increase incrementally across life-stages 2, 3 and 4 with a high point (inflection #1) around their 34th anniversary. It is expected, based on the life-cycle model, that funding requirements will decrease in Life-Stage 5 with a low point (inflection #2) in around their 50th anniversary.
