Q4+
• What is the impact of requesting X/Y/Z?
• What changes could be easily done to make the building operate more
efficiently?
• Increased maintenance associated with “sustainability”?
• Have you designed this before?
• Do I really need X/Y/Z?
• What will Part L 2014 mean to me?
• Are feed-in tariffs still worth it?

Summary
• Sustainability is complex
• Challenge your team to talk in plain English
• Know what you want
• Part L ≠ BREEAM ≠ Actual energy use
• CIBSETM54 key new tool in estimating actual
energy use
