(IS-2013-66) Do Green Buildings Outperform Conventional Buildings? Indoor Environment and Energy Performance in North American Offices
This report from the NRCC provides a comprehensive post-occupancy investigation of the performance of “green” and “conventional” office buildings. Green buildings exhibited superior indoor environment performance compared to similar conventional buildings. Outcomes that were better in green buildings included: environmental satisfaction, satisfaction with thermal conditions, satisfaction with view to the outside, aesthetic appearance, disturbance from HVAC (heating, ventilation and air conditioning) noise, workplace image, night-time sleep quality, mood, physical symptoms, and reduced number of airborne particulates.
