Integrated Design of Sustainable Buildings
Methods and tools

• Svend Svendsen
• Technical University of Denmark
• www.byg.dtu.dk, ss_at_byg.dtu.dk

2
Methods

• 1. Define Building Performance Requirements
• 2. Find Space of solutions
• 3. Propose and evaluate Provisional design
• 4. Propose and evaluate Detailed design

3
Building Performance Requirements

• Use (type, area ...)
• Indoor environment (thermal, atmosperic, visual,
  acoustic). Classes A,B,C
• Energy (total energy delivered). Low energy class
  1 (35 kWh/m2 )
• Architecture
• Other factors
• Total cost (initial and operating cost)

4
Space of solutions

• Possible parametric solutions of building design
  that fulfills the requirements
• Parameters
• Over all geometry of building (ratio of building
  envelope area to floor area)
• Facade design (window size and orientation)
• Energy performance of building elements and
  systems

5
Provisional designDetailed design

• Set up a number of design proposals
• Evaluate the proposals with respect to the
  performance requirements
• Iterate and decide

6
Tools for definition of Building Performance
Requirements

• Over view by use of tables and schemes
• Building codes and standards

7
Tools for findingSpace of solutions

• Office buildings Daylight and energy use

Tools for findingSpace of solutions - dwellings

• Based on early version of the official SBi
  program Be06
• Input the best performing components
• Program shows the relation of
• building geometries and
• window sizes and orientations

Tools for evaluations and decisions of
provisional and detailed design

• Be06 for documentation of energy performance
• Other programs for analysis of indoor environment
• MCDM Multi-Criteria Decisions Method
