“…This strategy is identical to the WAHP strategy discusses previously, except that the heat pipe system conditions 100% outdoor air and a parallel sensible device is operated, which is controlled by the thermostat in the space. Fricke and Sharma (2011) reported a 42% increase in dehumidification efficiency over the baseline with this strategy. The system is shown in Figure E3.…”

“…One improvement that can be made to the MAU strategy is the inclusion of an interior dehumidifier in the refrigerated section of the Sales Zone. This has been studied thoroughly (Fricke and Sharma 2011). We look at this scenario as well, which is referred to as "Interior Dehumidifier."…”

“…In applications in which the latent load in one area of the store is very high and the sensible load is small or negative, as in the refrigerated section of a supermarket, a dedicated interior dehumidifier may provide an energy-efficient means of conditioning the space. Fricke and Sharma (2011) have studied this concept in detail. The two types of interior dehumidifiers studied are described next.…”

“…The system was originally designed to be a residential whole-house dehumidifier with enough capacity to treat ventilation air, if necessary. Fricke and Sharma (2011) estimate that a 20% savings in refrigeration and HVAC energy is achievable with this type of system, as well as a 27% reduction in gas use.…”

This project was made possible with American Recovery and Reinvestment Act of 2009 funds. Thanks to Arah Schuur and Glenn Schatz of the U.S. Department of Energy Building Technologies Office for their support of the project. Knowledge of current heating, ventilation, and air conditioning (HVAC) industry best practices was made possible through generous input from designers and manufacturers who provided recommendations regarding HVAC design and control based on their extensive experience with supermarket design, construction, and operation.

“…An isolated sub-dehumidification HVAC system strategy was studied, which showed that a 20% savings in refrigeration and HVAC system electrical energy can be realized. 8 Various advanced technological solutions were implemented by using an eQuest model of big-box retail stores located in Canada in which an energy-use intensity reduction of 44% was achieved, mainly by alternative lighting and space heating strategies. 4…”

Calibrated building energy simulation is an important pathway to more energy-efficient buildings, but the information requirements of some approaches to this problem are significant. This is particularly true for supermarkets and other so-called “big-box” retail stores. Another characteristic of supermarkets is the significant interaction between Heating Ventilating and Air Conditioning (HVAC) and refrigeration systems in these buildings. These buildings could contain a wide variety of systems and a degree of load diversity that makes calibrated modeling a challenge. This paper describes a simplified approach that uses OpenStudio and EnergyPlus to combine known building parameters with “typical” parameters, resulting in a simplified building that is amenable to calibration. This approach was applied to a big-box store located in Nashville, Tennessee, and a calibrated model was obtained that was used to study potential energy conservation measures. The paper also explores the capabilities of whole-building energy modeling tools, such as EnergyPlus, for modeling the HVAC controls and sequences and their impact evaluation. Although some measures are precluded by the model simplicity, several measures were found to improve the efficiency of the model and demonstrate that the simplified modeling approach is effective. Practical Application: This paper introduces a hybrid approach of building energy model calibration using limited information available from the actual building in combination with characteristics of a “typical” building of the same type. This hybrid approach would also be applicable for other building types than discussed in this paper to calibrate the building energy model using limited information from the actual building.
