sensitivity analysis, daylighting, energy, perimeter offices


Utilization of daylight in perimeter office spaces introduces opportunities for energy savings. Daylighting performance is affected by many interfacing factors such as glazing size and properties, shading properties and control, interior surface reflectivity, climate and orientation. These factors also affect the thermal loads and hence the energy performance of the space. This paper investigates the sensitivity of daylighting and energy performance to the above mentioned factors based on simulations using a comprehensive model developed in a previous study. The design factors with more significant impact were identified using the MC-LHS method for uncertainty analysis and the variance-based FAST method for further sensitivity analysis. The results can be expanded to provide recommendations to building designers at the design and operational phases, for both new buildings and retrofit applications.
