Abstract
It is becoming increasingly crucial to develop methods and strategies to assess building performance under the changing climate and to yield a more sustainable and resilient design. However, the outputs of climate models have a coarse spatial and temporal resolution and cannot be used directly in building energy simulation tools. This paper reviews methods to develop fine spatial and temporal weather files that incorporate climate emissions scenarios by means of downscaling. An overview of the climate change impact on building energy performance is given, and potential adaptation and mitigation factors in response to the changing climate in the building sector are presented. Also, methods to reflect, propagate, and partition main sources of uncertainties in both weather files and buildings are summarized, and a sample approach to propagate the uncertainties is demonstrated.
Highlights
Buildings, through their lifecycle, play an important role in energy consumption and GreenhouseGas (GHG) emissions [1] both directly and indirectly
We review methods to generate future hourly weather files from climate change emission scenarios for building simulations
The Typical Year (TY) differ in their method for selecting representative months that are Design Summer Year (DSY)
Summary
Through their lifecycle, play an important role in energy consumption and Greenhouse. Gas (GHG) emissions [1] both directly (i.e., through its operation [2]) and indirectly (i.e., through the production of building materials [3], construction processes [4,5], transportation [6], rehabilitation, and demolition [7]) While these impacts underscore the importance of applying a dynamic approach [8,9,10] in life cycle assessments, the primary share of both energy consumption and environmental impacts takes place during a building’s operation [2,3,4,5,6,11,12]. We review methods to generate future hourly weather files from climate change emission scenarios for building simulations.
