Abstract

Windows are one of the main contributors to building energy consumption, and emerging dynamic window technologies offer improved performance. Specifically, NIRfocused window technologies are desirable in climates that consume both heating and cooling energy. However, the whole building energy effects of changeable NIR response of building windows have not been captured, largely due to the lack of an appropriate energy simulation method and NIR-focused window modeling. This study focuses on developing a simulation method that enables the comprehensive evaluation of the whole building energy effects of dynamic NIR modulations. Using an EnergyPlus EMS-based parametric framework, annual energy savings were estimated for a switchable between glass built-in system across three representative cities in ASHRAE climate zones 3, 4, and 5. This NIR-focused technology yielded energy savings of up to 19%. The results demonstrate the effects of NIR-focused window technologies on heating and cooling loads in different climates.
