“…Model validation is a phase that supersedes model fine-tuning. The validation process quantified the accuracy of results obtained by simulation, in comparison with the results obtained through measurements [23,24]. The criteria of eligibility, when the model is verified, are defined with the recommended statistical indicators.…”

The research analyses the double skin façades concept and their impact on the energy efficiency of buildings. This kind of façade system has the ability to increase the energy efficiency and flexibility of buildings, while improving the quality of the indoor environment. The best way to develop and evaluate this complex type of building structure is the use of total building performance simulation in combination with experimental data. The overall research plan is based on experimental work, the process of validation and the numerical simulation of the validated model. Thus, the task of this part of the research is a comparative analysis between the current state of a building with double skin façades and models with traditional envelope type. The main question that arises is whether and how the double skin façades may contribute to the decrease in the energy consumption of the building by increasing the quality of the thermal comfort of the occupants. The simulation software tool, EnergyPlus in combination with airflow network algorithm, is used for modelling and all necessary energy calculations. The validated model in the analysis is used for comparative evaluation with models with traditional façades. The simulation results for all the models analysed assess what their impact is on the energy consumption for heating and air-conditioning of the building. Comparing to models with traditional façade, the energy analysis shows justification in the climatic conditions of Belgrade. Additionally, simulations results highlighted the necessity for an adequate control strategy of the double skin façades application.

“…Although empirical validation procedures, based on real metering and auditing data, are considered as very reliable procedures [47], they are often used for the validation of tools and mathematical models developed for simulating specific phenomena. In this regard, the literature shows several examples of such a procedure applied to the validation of models relative to thermally activated building systems [48][49][50], daylighting or HVAC interactions with respect to window or solar gain [51,52], double skin facades or ventilated cavity [53][54][55][56], activities of occupants and their interaction with the building loads [57], etc. It is worth noting that though experimental validations of single mathematical models for the simulation of the energy performance of a specific new building's technology, component or material, can be often easily carried out, the experimental validation of whole BEPS tools is mostly unfeasible.…”

Building Energy Performance Analysis: An Experimental Validation of an In-House Dynamic Simulation Tool through a Real Test Room

et al. 2019

This paper focuses on the experimental validation of a building energy performance simulation tool by means of a comparative analysis between numerical results and measurements obtained on a real test room. The empirical tests were carried out for several months under variable weather conditions and in free-floating indoor temperature regime (switched off HVAC system). Measurements were exploited for validating an in-house simulation tool, implemented in MatLab and called DETECt, developed for dynamically assessing the energy performance of buildings. Results show that simulated indoor air and surface room temperatures resulted in very good agreement with the corresponding experimental data; the detected differences were often lower than 0.5 °C and almost always lower than 1 °C. Very low mean absolute and percentage errors were always achieved. In order to show the capabilities of the developed simulation tool, a suitable case study focused on innovative solar radiation high-reflective coatings, and infrared low-emissivity materials is also presented. The performance of these coatings and materials was investigated through a comparative analysis conducted to evaluate their heating and cooling energy saving potentials. Simulation results, obtained for the real test cell considered as equipped with such innovative coatings and material, show that for the weather zone of Naples a 5% saving is obtained both in summer and in winter by simultaneously adopting a high-reflectance coating and a low- emissivity plaster for roof/external walls and interior walls, respectively.

“…In order to assess the effects of DSF on the building energy consumptions and comfort, different mathematical models are coupled to building energy and airflow models or specific simulation software [16], [40], [41]. Although such software are often proved to be a good choice between simulation accuracy and simulation time [42], a lack of whole building simulation tools including advanced DSF is highlighted. It is also noted the need of models which are flexible with respect to the development of suitable operation strategies and the implementation of specific mathematical models [43], [44].…”

A numerical model is developed for simulating a single or multi-story Double Skin Façade integrating Photovoltaics (DSF-PV). The DSF-PV can co-generate solar electricity and heat while it also allows daylight to be transmitted to the interior space. The buoyancy-driven air flow inside the cavity may be assisted by a fan to cool down the photovoltaics while providing natural or hybrid ventilation to adjacent zones. Automated roller shades are also implemented in the model and help regulate heating and cooling loads but also control the daylight levels in the indoor space. A parametric analysis for different control strategies for the airflow within the cavity and the roller shading devices is performed with the purpose to apply the proposed methodology to minimize the heating and cooling demand of the DSF-PV system. In addition, a parametric analysis for different adjacent zones floor areas is performed. The simulations show that a DSF-PV system can supply approximately 120kWh/façade area/year covering the yearly electricity demand of the adjacent office if the floor area is approximately less than 3 times larger than the floor area.
