Can better thinking and better health be found in green-certified buildings?

1 All high-performing buildings surpassed ASHRAE Standard 62.1-2010 minimum acceptable person ventilation requirement and with low (<250 µg/m3) total volatile organic compound concentrations. 2 Green-certified buildings were certified under the USGBC® Leadership in Energy and Environmental Design® (LEED®) rating system.

Baseline

Leverage well-integrated solutions with the help of optimal use of information and planning.

Pay attention to situations at hand.

Gear decision-making toward overall goals.

Plan, stay prepared and strategize under

emergency conditions.

3 As defined by ASHRAE 55-2004; this is the range of temperatures and humidities within which less than 10% of occupants report being dissatisfied with thermal conditions.

A larger contrast between

daytime light exposure and

night-time light exposure

results in more melatonin,

a hormone that promotes

sleepiness, being released in

the evening (Takasu et al. 2006)

� COGfx: Buildingomics-Real-world setting, holistic approach

� The impact of buildings extends beyond working hours

�Designing to code is not enough

Implications

1 All high-performing buildings surpassed ASHRAE Standard 62.1-2010 minimum acceptable person ventilation requirement and with low (<250 µg/m3) total volatile organic compound concentrations.

Conclusions

In certified buildings:

�Improved perception of IEQ

�Fewer symptoms

�Higher cognitive function scores

�Better sleep score
