The aim of this paper is to demonstrate the use of TRNLizard, an integrated thermal, daylight and airflow simulation tool based on Rhinoceros 5, Grasshopper, TRNSYS18, DaySIM and TRNFlow to develop and validate the concept for an energy efficient office building with a healthy, comfortable environment. However, some passive measures such as natural ventilation are more difficult to simulate and validate due to the complex, non-linear relationship between wind forces and thermal buoyancy. To help drive first decisions, an accurate and fast simulation tool that considers dynamic thermal, daylight and airflow models is required. Such design needs special considerations at the early stages that significantly affect decisions regarding passive strategies. It is shown that measures to create an exceptional, healthy environment for occupants drive conservation and energy efficiency. This paper argues that wellness and energy savings are not contradictory aspects of design. Some practitioners, therefore, prefer a fully sealed facМ§ade with a low glazing ratio to reduce energy consumption. However, their energy efficiency and impact on occupant comfort вЂ“ thermal, glare and visual вЂ“ are questioned. Designers and architects tend to lean towards fully glazed buildings in a multi-floor office building due to its light structure, transparency and more access to daylight compared to traditional buildings. Abstract: Despite growing interest in sustainable office buildings and technological advancements, often either comfort or energy is sacrificed at the expense of the other in the conventional approach.
