Why? Poem attributed to Martin Niemöller that
was said to have been written in 1946.

• "First they came for the Communists, but I was
  not a Communist, so I said nothing.
• Then they came for the Social Democrats, but I
  was not a Social Democrat, so I did nothing.
• Then they came for the trade unionists, but I was
  not a trade unionist.

Poem attributed to Martin Niemöller

• And then they came for the Jews, but I was not a
  Jew, so I did little.
• Then when they came for me, there was no one left
  to stand up for me."

Our approach

• More sustainable buildings at SHU
• Reduced energy consumption
• Reduced environmental impact
• Improve internal environmental conditions
• Extended useful life of plant

12
Our approach Why we do not formally use BREEAM ?

• Simple procedure
• Benefit in Using Methodology with design team
• Not too interested in collecting gongs

Heath and Wellbeing Building
14
Health and Well Being Building
15
Our approach Example 1 - Health and Well Being
Building
16
Our approach Key Areas identified

• Improved our commissioning requirements prelim
  clauses tightened
• Identified the need to optimise floor to ceiling
  dimension
• Maximise lettable office floor area being
  adequately daylit
• Where air intakes serving occupied areas avoid
  major sources of external pollution

17
Example 2 - ACES building

• We established that the Collective vision of the
  client and the design team was
• Provision of an eco friendly low energy building
• Provide a high quality durable and attractive
  environment
