Introduction…

Efficient Façade Design for Architects

Building Analysis Software and Processes are Complex, consider

Multiple Aspects of the building and requires the building

to be Practically Designed and

therefore are Used Late in

the Design Process

So what problem does this solve?

So what problem does this solve?

REDUCE TIME, SAVE MONEY, MAINTAIN AESTHETIC CONTROL

How does it solve the problem?

A decision making tool, guidance and considerations to

optimise energy consumption and occupant comfort

when replacing façades on existing office buildings.

Supervisor: Dr. Steve Lo

September 2011.

MSc in Architectural Engineering:

Façade Engineering

Research – Title

The aims of the dissertation where to: Establish the impact of the façade on occupant comfort and energy

consumption in existing office buildings.

Create a set of office typologies considering the impact of the façade on

existing office buildings and set out notional reference buildings based on

these typologies.

Evaluate criteria for the selection of optimised replacement façades.

Develop a decision making tool, guidance and considerations to optimise

occupant comfort while reducing energy consumption in existing office

buildings when replacing the façade.

Use the notional reference buildings to review the effectiveness of the

decision tool, guidance and considerations.
