Whole building design

Traditionally building systems were viewed separately and decisions were taken according to schedule or budget, priorities were not based on the final building performance and specialists worked in isolation for the most part.

The whole building design is an integrative design that has interbuilding considerations that result in greater efficiencies where all building systems operate interdependently where green thinking applies first to a project as a whole then to every stage in the lifecycle and requires collaboration among design professionals and other stake holders through out the project phases.


Choosing the proper insulation that is most effective for HVAC system is an example of integrative approach that integrates systems, people and best practices that optimize the project results.

The integrative process of a project phases which are additional to the typical process of a traditional project are:

  • Pre-Design
  • Demolition / Recycling

It is the most critical phase where the project should take into consideration green building goals while collecting project information from various stakeholders, it has imbedded steps:

  1. Life Cycle approach that focus on all project phases up to demolition or recycling.
  2. Clear statement of project vision defining what the project is intended to accomplish
  3. Define the clear, achievable and measurable Green goals of the building that support the project vision



Project goals should be checked Continuously against the project vision to see if they are being met, which requires both clear metrics and targets.

If goals are achievable based on cost and/or schedule could not be achieved, then goals should be prioritized by project team.
