This study presents a comparative analysis of cascade and single heat pump systems for simultaneous cooling and domestic hot water supply,aimed at supporting building electrification and carbon neutrality goals.The novelty of this work lies in its integrated experimental and simulation-based evaluation of cascade heat pump performance,addressing a gap in existing studies that typically analyze either mode separately.A field test was conducted in a real building environment using two configurations:a cascade heat pump system managing both cooling and hot water functions,and two separate single heat pumps.Performance metrics such as cooling energy efficiency ratio and hot water coefficient of performance were measured and compared under identical boundary conditions.In addition,a transient simulation study was carried out using transient simulation tool for representative summer days in office and residential buildings,assessing primary energy consumption and carbon emissions based on experimental data.The cascade system achieved up to 15.3%improvement in energy efficiency ratio,23.7%reduction in primary energy use for office buildings,and up to 24%reduction in CO2emissions.These findings demonstrate the practical applicability of cascade heat pumps in energy-saving retrofit projects,especially for space-constrained buildings,and provide empirical and simulation-based evidence supporting their integration into sustainable building strategies. 展开更多

Weather files strongly influence building performance simulation,especially in climatically diverse countries such as Brazil.Yet,the representativeness of typical meteorological years(TMY)for Brazilian applications remains insufficiently assessed.This study aims to evaluate four established TMY approaches and to introduce a performance-based alternative(Brazilian typical meteorological year,BTMY)that incorporates building-specific climatic sensitivity.Using ERA5-Land data for 480 locations,we compiled 15 actual meteorological years(2008–2022)per site and assessed their impact on operative temperature and energy needs in representative residential models.Spearman filtering removed collinear meteorological parameters,and optimized XGBoost andε-SVR models predicted daily operative temperature with R2=0.91±0.03(RMSE=0.64±0.19°C)and daily energy needs with R2=0.87±0.05(RMSE=0.05±0.01 kWh m−2 yr−1),identifying dry-bulb temperature as the dominant meteorological parameter(75%importance for operative temperature;59%for energy needs).Against 15-year simulations,minimum Finkelstein–Schafer and Best Rank I achieved the lowest mean operative-temperature bias(0.15℃,SD 0.09-0.10℃),ISO was similar(0.16±0.13℃),while Pissimanis performed worst(0.23±0.27℃).BTMY weather files matched the TMY methods and clarified key climatic drivers.Results showed that ERA5-Land data source mattered more than the reference-year method.Finally,the study delivered more than 3000 new weather files to support simulation practice and policy development. 展开更多

Comprehensive dynamic building simulations are used in order to conduct sensitivity analyses on the influence of building shell parameters to the heating and cooling demands of a variety of building types in Morocco. In a first step, five climatic zones are defined covering the range of specific heating and cooling demand combinations of a reference building located in eleven locations throughout Morocco. Afterwards, 22 single parameter variations for each building type and each climate zone are performed and analyzed in such a way, that suitable promising combinations can be defined as well. This procedure is faster and easier to analyze than a multidimensional regression. The results show indeed that the selected combinations may reduce energy demands substantially. This paper explains the procedure and results in detail for one residential type of building and for one typical non-residential building. The major overall results are discussed. 展开更多

Multi-dimensional heat transfers modeling is crucial for building simulations of insulated buildings,which are widely used and have multi-dimensional heat transfers characteristics.For this work,state-model-reduction techniques were used to develop a reduced low-order model of multi-dimensional heat transfers.With hot box experiment of hollow block wall,heat flow relative errors between experiment and low-order model predication were less than 8% and the largest errors were less than 3%.Also,frequency responses of five typical walls,each with different thermal masses or insulation modes,the low-order model and the complete model showed that the low-order model results agree very well in the lower excitation frequency band with deviations appearing only at high frequency.Furthermore,low-order model was used on intersection thermal bridge of a floor slab and exterior wall.Results show that errors between the two models are very small.This low-order model could be coupled with most existing simulation software for different thermal mass envelope analyses to make up for differences between the multi-dimensional and one-dimensional models,simultaneously simplifying simulation calculations. 展开更多

Building simulation is a powerful way to evaluate the performance of a building.The quality of simulation results however strongly depends on the accuracy of simulation input data.Especially for weather data files and occupant behaviour it is difficult to obtain accurate data.This paper evaluates the variability of building simulation results with regards to different weather data sets as well as different heating and cooling set points for a residential building in Victoria,Australia.Thermal comfort accord-ing to ASHRAE Standard 55,final energy consumption and peak cooling and heating loads are assessed.Simulations have been performed with Energy-Plus,and weather data for a multi-year approach have been generated with the software Meteonorm.The results show that different weather files for the same location as well as different conditioning set points can influence the results by approximately a factor of 2. 展开更多

To reach this goal, it is pertinent for buildings to be energetically optimized first. The remaining energy demand must then be covered by on-site renewable energies (PV, geothermal, etc.). With the area of use (energy demand) and the size of the building envelope/estate (renewable energy supply) in competition with each other, the maximum number of building stories will be most likely limited. For 15 different climatic locations worldwide, the energy demand of optimised office rooms has been simulated and compared with the possible renewable energy production on site. For every location, a good correlation has been found between the simulated energy demand and data like heating and cooling degree hours. Correspondent linear equations are given here. As another result, the maximum numbers of possible stories for ZEBS have been derived, being between 3 and 10 depending on the location. 展开更多

In this paper the possibilities for avoiding active air conditioning by all means of the room itself (window size, glazing, shading system, natural ventilation, and furniture), artificial light and control strategy of these systems are investigated. A very important component of the system is the user with his ability to adapt to changing conditions in his surrounding and with his possibilities to manipulate the window, the shading system, the light switch etc. All these aspects interact together. It is necessary to optimize them simultaneously. But real planning often separates them into single sections. Simulation tools also handle normally only one or a few aspects, we know for example the thermal simulation or the daylight simulation. Primero-Comfort (2009) is a simulation tool based on energy+, what is able to consider thermal simulation as well as daylight simulation as well as user behaviour in regard to the probability of window openings. The resulting thermal comfort is rated by an adaptive comfort model, the Dutch ISSO 74 (2004). This allows designing office rooms more realistic. And it shows that an optimized solution has to include the interactions of aU mentioned aspects. Investigations with Primero-Comfort for a moderate European climate (Hamburg) show that a very good comfort can be reached only by passive means of building design also for hot summer weather just like the summer in the year 2003. The keys for such hot-summer-robust-buildings are night ventilation with height difference, heat protection glazing and good shading system, reduced internal heat gains for artificial light by accepting a threshold of 300 lx of daylight as comfortable and a reduced window size oriented on daylighting and the view out of the window. 展开更多

Building energy use accounts for over one-third of global demand,making reliable energy modeling critical for efficiency and decarbonization.While many studies emphasize the role of weather in building energy simulations,the way climate variability shapes parameter sensitivities and calibration priorities has not been sufficiently clarified.This study compares parameter rankings across four representative climates and demonstrates how climatic context shapes model behavior,highlighting the need to consider climate-specific drivers in building performance evaluation.Specifically,we investigate climates'influence on the monthly calibration performance of multi-output energy simulation models targeting energy-related objectives such as"Electricity:Facility"and"InteriorLights:Electricity"across four distinct global Köppen climate zones(Dwa,Cfa,Cfb,and Af).The results reveal that the most sensitive parameters in Bayesian calibration vary significantly across four typical climates.We also used a composite seasonal index for evaluating climate variability.It showed that the Dwa climate,with the highest variability,had the highest coefficient of variation of the root mean square error(CVRMSE)at approximately 10%,while the Af climate demonstrated the lowest,at around 6%.Furthermore,we observed that parameters calibrated and models trained under existing climatic conditions are inadequate for predicting future energy consumption,averagely resulting in 10.11%higher CVRMSE and increased uncertainties.These findings contribute to our better understanding of climatic impacts in building energy modeling,essential for mitigating energy consumption in the face of global climate change. 展开更多

Thermal comfort and indoor air quality as well as the energy efficiency have been recognized as essential parts of sustainable building assessment. This work aims to analyze the energy conservation of the heat recovery ventilator and to investigate the effect of the air supply arrangement. Three types of mixing ventilation are chosen for the analysis of coupling ANSYS/FLUENT (a computational fluid dynamics (CFD) program) with TRNSYS (a building energy simulation (BES) software). The adoption of mutual complementary boundary conditions for CFD and BES provides more accurate and complete information of indoor air distribution and thermal performance in buildings. A typical office-space situated in a middle storey is chosen for the analysis. The office-space is equipped with air-conditioners on the ceiling. A heat recovery ventilation system directly supplies flesh air to the office space. Its thermal performance and indoor air distribution predicted by the coupled method are compared under three types of ventilation system. When the supply and return openings for ventilation are arranged on the ceiling, there is no critical difference between the predictions of the coupled method and BES on the energy consumption of HVAC because PID control is adopted for the supply air temperature of the occupied zone. On the other hand, approximately 21% discrepancy for the heat recovery estimation in the maximum between the simulated results of coupled method and BES-only can be obviously found in the floor air supply ventilation case. The discrepancy emphasizes the necessity of coupling CFD with BES when vertical air temperature gradient exists. Our future target is to estimate the optimum design of heat recovery ventilation system to control CO2 concentration by adjusting flow rate of flesh air. 展开更多

Integrated building design is inherently a multi-objective optimization problem where two or more conflicting objectives must be minimized and/or maximized concurrently.Many multi-objective optimization algorithms have been developed;however few of them are tested in solving building design problems.This paper compares performance of seven commonly-used multi-objective evolutionary optimization algorithms in solving the design problem of a nearly zero energy building(n ZEB) where more than 1.610 solutions would be possible.The compared algorithms include a controlled non-dominated sorting genetic algorithm witha passive archive(p NSGA-II),a multi-objective particle swarm optimization(MOPSO),a two-phase optimization using the genetic algorithm(PR_GA),an elitist non-dominated sorting evolution strategy(ENSES),a multi-objective evolutionary algorithm based on the concept of epsilon dominance(ev MOGA),a multi-objective differential evolution algorithm(sp MODE-II),and a multi-objective dragonfly algorithm(MODA).Several criteria was used to compare performance of these algorithms.In most cases,the quality of the obtained solutions was improved when the number of generations was increased.The optimization results of running each algorithm20 times with gradually increasing number of evaluations indicated that the PR_GA algorithm had a high repeatability to explore a large area of the solution-space and achieved close-to-optimal solutions with a good diversity,followed by the p NSGA-II,ev MOGA and sp MODE-II.Uncompetitive results were achieved by the ENSES,MOPSO and MODA in most running cases.The study also found that 1400-1800 were minimum required number of evaluations to stabilize optimization results of the building energy model. 展开更多
