Lecture 2 - Design Methods

BASED Design Method

BASED An Architectural Design Method The method is primarily a means of resolving a conflict that exists between logical analysis and creative thought.

Steps of the BASED Design Process • Briefing • Site selection, Program formulation, Data collection, Examples, ...

• Analysis • Design and Project Data analysis • Identification of Objectives

• Synthesis • Formulation of Concepts and Alternatives • Communication of Concepts

• Evaluation • Review of Alternatives • Selection of one alternative

• Design • Design details • Communication media

(Analyze)

Identify User Needs

1. Need Design Data An important activity in the beginning of the design process is the collection of relevant design data and examples.

2. Context

• Site • Zoning • Services • Macro Climate • Micro Climate • Adjacent Buildings • Geographical Factors • Vehicular Access

3. Form

• Zoning • Circulation • Structure • Enclosure • Construction Type • Construction Process • Energy • Climate Control • Image

Design Considerations - Facts • Environmental (site and climate) – Visual illustration of the location of the project: • • • • •

The city or region in which the site is located Its immediate environmental context The characteristics of the site The climate and microclimate Other information.

Design Considerations - Facts • Technical – Controlled temperature or humidity requirements – Materials and finishes – Solutions similar to existing ones or alternative approaches

Design Considerations - Facts • Other (facts or needs?)

– – – – – –

Image of facility Signage and way-finding Form and color Energy conservation Safety and accessibility Budget and time

Space Identification and Allocation • Tabular presentation – Brown sheets or Grid sheets – Appropriate size for each space

Space Identification and Allocation • Building efficiency – Estimate the amount of additional square footage (meters) that will be required to account for unprogrammed spaces including: • • • • • •

Circulation spaces Walls Mechanical and electric rooms Janitor’s closets Rest rooms Miscellaneous storage

Space Identification and Allocation • Building efficiency – – – –

Very substantial percent of the building area Net-to-Gross Ratio or Building Efficiency Varies significantly for different building types If it is accounted for incorrectly, it can have a significant negative impact on building quality.

Building efficiency

Efficiency = Net Area / Gross Area

Space Identification and Allocation • Building efficiency – Calculation of efficiency:

Net Area = Gross Area Efficiency 6000 m2 60%

= 10,000 m2
