Green Buildings: Minimum Design Service Life for Buildings

Tuesday, June 23rd, 2009

The following is my own recommendation for the definition for a green building’s minimum design service life – David Slade

This is now set out in BSR/ASHRAE/USGBC/IESNA Standard 189.1P, Standard for the Design of High-Performance Green Buildings Except Low-Rise Residential Buildings, now at its Third Public Review Draft stage.

A Service Life Plan that is consistent with the owner’s project requirements shall be developed to estimate to what extent structural, building envelope (not mechanical and electrical), and hardscape materials will need to be repaired or replaced during the service life of the building. The design service life of the building shall be no less than that determined. The estimated service life shall be documented for building assemblies, products, and materials that will need to be inspected, repaired and/or replaced during the service life of the building. Site improvements and hardscape shall also be included. Documentation in the Service Life Plan shall include the building project design service life and basis for determination, and the following for each assembly or component:

  1. Building assembly description.
  2. Materials or products.
  3. Design or estimated service life, years
  4. Maintenance frequency.
  5. Maintenance access for components with an estimated service life less than the service life of the building.

Provide a Service Life Plan at the completion of design development. The owner shall retain a copy of the Service Life Plan for use during the life of building.
