Design & Iterate
Having analysed a range of factors, we have discovered that some are more
important than others. By combining the best glazing ratio, shading, and a heavy
structure, overall we were able to achieve:
As we continue to design, we can continue to use performance feedback to in-
form our design decisions — ensuring that our final design performs beautifully.
•
A reduction in EUI from 102kWh/m2 or 32KBTU/ft2 (original Part L
baseline) to 61kWh/m2 or 19KBTU/ft2 - also meaning we fell well under
the Architecture 2030 target of 105.
•
A massive 74% reduction in cooling load and therefore a smaller, cheaper
HVAC system.
•
27% reduction in both CO2 production and utility costs.
By testing their intuition, rules of thumb and assumptions, architects can clearly
understand the tradeoffs between their design decisions and the building's
performance. Armed with this data, decisions about facade design -- glazing
ratios, material specification, thermal mass and shading -- can be made with a
combination of robust data and creativity.
