Building Ventilation

This paper proposed HVAC engineer should simulate natural ventilation () of building based on the Ventilation Network Model (VNM) and software of loop pipe network hydraulic calculation and analysis of hydraulic conditions (LPNHHC) V1.0 which is developed by Chongqing University. It presents two indexes, which are requirement of ventilation in local building regulation () and thermal comfortable ventilation (), should be used to evaluate the design talent on building natural ventilation. We can say the building ventilation design meet the requirement under the premise of bigger than and simultaneously. Architecture, otherwise, needs to modify the building design according to the comments of HVAC engineer. HVAC engineer should design mechanical ventilation (MV) if natural ventilation really can not meet the requirement after modification. It, at last, shows a case study of office building in Chongqing in order to prove the method proposed in the paper. We conclude that ventilation network model can be used to evaluate the design effect of building natural ventilation.

As the major public buildings and cultural service institutions, libraries play an important role in the strategy of energy-saving buildings. In order to keep pace with the footstep of Western developed countries, China has launched a series of green and energy-saving building practices and achieved certain results. The New Hubei Library is a successful example, with Chinese national conditions and the characteristic of the library itself taken into consideration, and limited conditions in the design process fully made the most use of. Besides the designer has efficiently used energy-saving strategy on building structure maintenance, solar radiation, air conditioning control system and natural ventilation, finally achieved the goal of energy saving of library.

AbstractThis research focuses on the energy performance of office building in Wuhan. The research explored and predicted the optimal solution of design variables by Multi-Island Genetic Algorithm (MIGA) and RBF Artificial neural networks (RBF-ANNs). Research analyzed the cluster centers of design variable by K-means cluster method. In the study, the RBF-ANNs model was established by 1,000 simulation cases. The RMSE (root mean square error) of the RBF-ANNs model in different energy aspects does not exceed 15%. Comparing to the reference case (the largest energy consumption case in the optimization), the 214 elite cases in RBF-ANNs model save at least 37.5% energy. By the cluster centers of the design variables in the elite cases, the study summarized the benchmark of 14 design variables and also suggested a building energy guidance for Wuhan office building design.

The influence of courtyard on the thermal performance of Development Department office building in University Malaysia Perlis (UniMAP, Pauh Putra campus) is investigated through simulation study for the effect of ventilation on indoor air temperature and relative humidity of the building. The study is carried out using EnergyPlus simulator interface within OpenStudio and SketchUp plug in software to measure both of air temperature and relative humidity hourly on 21 April 2017 as a design day. The results show that the ventilation through the windows facing the courtyard has sufficient effect on reducing the air temperature compared to the ventilation through external windows since natural ventilation is highly effective on driving the indoor warm air out to courtyard. In addition, the relative humidity is reduced due to ventilation since the courtyard has high ability to remove or dilute indoor airborne pollutants coming from indoor sources. This indicates that the presence of courtyard is highly influential on thermal performance of the building.
