Uncertainties in energy and economic performance of HVAC systems and energy recovery ventilators due to uncertainties in building and HVAC parameters

Dynamic energy performance analysis: Case study for energy efficiency retrofits of hospital buildings

“…[3]). In this regard, the current literature suggests that achievable energy savings can be obtained by: adopting new ventilation strategies and more efficient technologies [11]; by optimizing the configurations of air distribution hospital rooms [13]; by taking into account adaptive VAV (variable air ventilation) operation [14,16]; by adopting heat recovery units [17] ad energy recovery ventilators [18]. In order to improve the resilience of the existing hospitals, the importance of good practices in the maintenance and repair of existing energy services and the adoption of low cost measures, that do not interfere with the functioning of the hospital, are recommended.…”

A methodology for predicting the energy performance and indoor thermal comfort of residential stocks on the neighbourhood and city scales. A case study in Spain

“…Although a local sensitivity analysis has been conducted in several literature reports (Demanuele et al, 2010;Kavgic et al, 2013;Lam and Hui, 1996;Rasouli et al, 2013), this study applied a global sensitivity method through INLA to analyse the interactions among covariates and to explain how much variations of the response variables are accounted by covariates. A sensitivity analysis was conducted by varying the value adopted by these covariates and by analysing the effect of these changes on the response variables.…”

“…HVAC chiller efficiency improvement [34][35][36] : The efficiency of chillers can be improved by lowering the temperature of the condenser water, thereby increasing the chilled water temperature differential. This can reduce pumping energy requirements.…”
