Even if a Integrated Asset Delivery Framework
Building doesnt look unusual, it can save in the
order of 50 in energy and greenhouse gas
emissions, compared to current good practice.
Much of this is due to a new design process, one
based on the well-tested principles of skills and
teamwork.

What is Integrated Asset Delivery Framework?

• Integrated Asset Delivery Framework is a program
  for the delivery of high-performance buildings.
  The goal is to help designers to achieve a very
  high level of performance, including
• A 50 improvement in energy performance relative
  to current good practice,
• Reductions in resource consumption, such as land,
  water and materials,
• Significant reductions in atmospheric emissions,
  solid and liquid wastes,
• Superior indoor air quality, thermal comfort,
  illumination and acoustic environment,
• Improved functionality, adaptability and
  maintainability.

4
The conventional design process

• To assess the Integrated Asset Delivery
  Framework, we first need to examine the
  conventional design process. It is essentially
  linear in nature

5
The conventional design process

• It begins with pre-design functions, such as the
  preparation of a Design Brief and Functional
  Program, to be carried out by the client. This is
  followed by the first two phases within the
  responsibility of the design team, Schematic
  Design and Design Development. Percentage figures
  indicate recommended percentage of total fees
  allocated to the task.

The conventional design process

• These are in turn followed by Detail
  Documentation (drawings and specs), Tender
  Process, and Site Inspections during the
  Construction Stage. These three phases account
  for 75 of the total fees.

7
The conventional design process

• In the conventional process, attempts are often
  made to introduce bright ideas during the
  preparation of construction documents (or even
  later!), since they were not considered earlier.
  This is costly and disruptive to the process.

8
The conventional design process

• To summarise the problems
• The main design parameters (massing, orientation,
  fenestration pattern) are often determined by the
  client and architect in the Schematic Design
  phase.
• Input on orientation for passive solar,
  daylighting potential, measures to control solar
  overheating etc. is often only sought in the
  Design Development phase.
• By this time, the client and architect may be
  locked into a sub-optimal solution

9
The conventional design process

• problems
• Engineers and specialists are locked out of the
  initial design decisions, and architects are
  poorly placed to acquire detailed knowledge about
  new technologies and processes such as
  performance simulation.
• Advanced systems and features are often added
  on to the basic design in later phases, but this
  does not lead to very high levels of performance,
  disrupts the process, and is very costly.
• Or design in haste, repent at leisure.

Conventional Process
11
Integrated Asset Delivery Framework

• We define the integrated development process as
• Including a wide range of technical skills in the
  design team,
• Adding a design facilitator and an energy
  simulation specialist to the team,
• Commencing with teamwork from the very start of
  the Concept Design Stage,
• Adding new functions to the process, and
• Defining performance goals at the outset and
  referring to them throughout.

12
Integrated Asset Delivery Framework

• What are the features of the Integrated Asset
  Delivery Framework?
• It brings engineering and specialist skills to
  the table at a very early stage.
• A broad range of performance issues are
  considered.
• It keeps options open on the basic features of
  the design until the potential performance of
  alternatives can be assessed.
• Conversely, the client is not hustled into a
  premature commitment to a primarily visual
  solution.

13
Integrated Asset Delivery Framework

• What are the features...?
• The architect plays the role of a team leader and
  is not the predominant decision-maker during
  Concept Design and Design Development.
• Friction can be avoided by informing consultants
  about the process before they are retained.
• The architect acquires valuable new technical
  skills, while the client and engineers gain
  insight into the complexities of architectural
  design.
• Engineers have a chance to show how much they can
  contribute to the early design phases.

14
Integrated Asset Delivery Framework

• What are the features...?
• Integrated Asset Delivery Framework provides
  access to specialists as needed for short-term
  advice, such as daylighting, thermal storage,
  glazing characteristics, material selection, etc.
• Note that, as in conventional projects, most of
  the hard work is up to the design team. The
  program is not intended for neophyte designers,
  and our process just provides support and helps
  the team to make the right decisions.

The first step is to work with the client to
ensure that the right team is in place before
design begins

Integrated Asset Delivery Framework

• It is important to note that
• The architect and engineers still retain their
  professional responsibilities and liabilities,
  and therefore are the final arbiters of design
  decisions.
• The Design Facilitator is to be an adviser, and
  is to support the design team in their work
  without disrupting the process. This requires an
  ability to make rapid decisions and also to
  provide helpful information and support quickly.
• The design professionals should be paid on a
  lump-sum basis or equivalent that will avoid
  penalising them financially for reducing the size
  and cost of mechanical systems.

18
Integrated Asset Delivery Framework

• Before design work begins, some preliminary
  questions should be asked
• Could a renovation serve the purpose instead of a
  new building?
• If new construction is needed, has the best site
  been chosen, e.g. avoiding the use of
  agricultural land?
• Has the design brief and functional program been
  developed with due care?

New technologies and procedures are implemented
A way to summarise the technical aspects of the
process is to think of it this way

• First make use of the passive solar potential by
  using orientation and configuration to maximize
  solar potential during the heating season and
  daylighting all year around

• Second, reduce heating and cooling loads through
  the use of a high-performance building envelope,
  carefully located glazing and by reducing
  electrical consumption

• Then meet the reduced load requirements through
  efficient plant systems and distribution
  systems...

• while always remembering the need for a
  high-quality indoor environment, maintainability,
  economy and measures to reduce environmental
  loads.

26
New technologies and procedures are implemented
Specific design features depend on the specific
building and its location nevertheless consider
the following

• Provision of adequate space for bicycles and
  solid waste recycling,

• High-volume flyash cement and a lean structure,

• Trees as part of the solution to reduce cooling
  loads,

• Spectrally-selective glazing with exterior
  sunshades and light shelves to maximize
  daylighting potential,

• High-efficiency direct/indirect ambient lighting
  plus task lighting,

• Daylight sensors for perimeter lighting zones,

27
New technologies and procedures are implemented
Specific design features to consider...

• Use of natural ventilation where possible,

• Operable windows or a backup ventilation system,

• 100 displacement fresh air system with heat
  recovery,

• Sizing of drives, boiler chillers to maximize
  operation at full loads.

• Minimal size of lighting and HVAC zones,

• Control systems that are user-friendly and are
  consistent with the complexity of building
  systems,

• Materials chosen for low emissivity and embodied
  energy, use of recycled materials, and an
  assembly design that focuses on future
  demountability.

28
Integrated Asset Delivery Framework
What are the results?

• More time is spent in Concept and Design
  Development tasks, but time is saved and problems
  are minimized during the contract documentation
  stage.

• The process results in better buildings ones
  with energy and emission performance roughly half
  of current good practice, healthier and more
  comfortable indoor environments, and with more
  ability to adapt to changing future needs.

• Operating costs are considerably reduced because
  of reduced operating energy consumption.

• Maintenance and replacement costs are reduced
  because of smaller mechanical plants and more
  efficient equipment.
