Sustainable & Green Design
Sustainable design is the philosophy of designing physical objects,
the built environment, and services to comply with the principles of
social, economic, and ecological sustainability.
https://en.wikipedia.org/wiki/Sustainable_design

Green Design and construction practices that significantly reduce, or

eliminate the negative impact of buildings on the environment and its
occupants. (US Green Building Council)

Sustainability Approaches: site planning; safeguarding water use

and water use efficiency; promoting energy efficiency and
renewable energy; conserving materials and resources; and
promoting indoor environmental quality

Leadership in Energy & Environmental Design

A leading-edge system for designing,

constructing, operating and certifying the
worlds greenest buildings.

LEED project certification -

provides independent, third-party
verification that a building project
meets the highest green building and
performance measures.

United States Green Building

Council (USGBC) issued a set of
LEED guidelines in 2000.

 QFD for customer satisfaction

In a total quality setting, customers define quality. Therefore,

customer satisfaction must be the highest priority.

Customer satisfaction is achieved by producing high-quality

products/services that meet or exceed expectations.

Customer needs are not static. Therefore, constant contact with

customers is essential in a total quality setting.

QFD can be used to update customer needs (get feedback

periodically) and enhance products/services accordingly.
 Quality Function Deployment
(House of Quality)

The QFDs House of

Quality (HOQ) is the
heart of QFD.

It is the set of
interrelated matrices
known that take on
the appearance of a
house.
 QFD in Sustainability: SFD

QFD can be used to consider the sustainability requirements
in the design (Sustainability Function Deployment: SFD).

It makes sustainability requirements a normal part of

architectural design, thereby improving the quality of living
and the quality of the environment.

In order to implement SFD, designers must innovate. They

need to identify the mechanisms/actions/technical
requirements that fulfill the sustainability requirements.

QFD/SFD is a mechanism for innovation.

WHATs in SFD

 Sustainability requirements
Interior Air Quality
Less Energy consumption
Less Water consumption
Clean external air
Natural light
others

 Each team should come up with a list of WHATs

 Team has to agree on their importance
 Team has to benchmark them with LEED & Estidamah

20
HOWs in SFD

 Technical requirements to achieve the WHATs

Solar
Cooling
Recycling
Design

others
 Each team should come up with a list of HOWs
 Team has to agree on their relationships with WHATs
 Team has to identify correlations within HOWs and
suggest how to deal with contradictions
 Team will set design targets for the HOWs

21
 Example
DEWA, Dubai Electricity and Water Authority, in AlQuz, Dubai, UAE.

In December 2012, the project was occupied and received the certification with a total LEED score of 98
out of 110 (Platinum).

Example: At the roof, they added a sky garden to further enhance the indoor and outdoor thermal
environment.

 Matrix Number #2: Planning the Improvement Strategy
- In this matrix, it provides DEWA assessment compared to the most well known benchmarks within the
region which are Estidama and LEED
- Estidama is the green building rating tool that is used in Abu Dhabi and it consists of 5 pearl according to
each sustainability principles
- LEED is a US benchmark assessment tool used for green sustainable buildings
- With the assessment of the benchmarks and the customer importance, the improvement factor, sales
point, overall weight and total percentage of the overall weight were calculated for DEWA

Matrix Number 3Selecting the Technical Requirements (HOWs)
Matrix Number #4: Evaluating Interrelationships between the
WHATs and HOWs.
- In each intersection between the technical requirement and the customer need, an interrelationship was
estimated either strong, medium, weak or none presented in different shapes

- The purpose of this matrix is to show how strong is the relationship between each technical requirement
with the customer need, this will later show which technical requirement is consider as a priority for the
customer and therefore the designer should invest more in it

High = 9

 Matrix Number #5: Evaluates the Correlation
- Within each diagonal intersection in the correlation matrix, a supportive or impeding type of relation
ship is established between the technical requirements
- These correlations exist as the roof of the HOQ ( House of Quality )
- The positive and the negative sign shows if the two technical requirement support each other or which
one of them oppose each other

- The design target matrix includes calculation of the technical priorities

- The higher the value shows the importance of implementing the technical requirement in the project design

- According to the calculation, the high efficiency HVAC, operable window and artificial light contributes greatly
in the project design

Another Example: Redesign of superblock

There is a need to revitalize the inner part of the city. This is about what is needed for the city. So, Abu Dhabi
2030 Plan proposes a program of block revitalization, undertaking one or several pilot projects. The goals
here are the following:

To analyze the existing situation.

To identify the issues that may cause the blocks to deteriorate.
To pinpoint all drawbacks and create proposals concerning the urban morphology, public space, volumes, as
well as social segregation and road/pedestrian networks.

By this, the modern concept Abu Dhabi may redefine its urban fabric in a more socially viable and
sustainable way that has the potential of becoming the prime design to be followed.
