Determining the Evaluation of Daylight Parameters on the Basis Simulation Model for the Tropical Climate | Chapter 11 | Current Approaches in Science and Technology Research Vol. 12

 In terms of illumination levels and health advantages, using natural sunshine in the building saves energy. In the hot and dry climatic zone, however, an increase in daylight availability could lead to heat infiltration. This could lead to an excessive amount of energy conservation. The goal of this study is to provide a methodology that can be utilised as a pre-design tool for evaluating lighting and thermal performance of areas within buildings that designers may use during the design process. The field measurements were taken on the liveable spaces of a Nagpur-area housing unit. Both illumination and thermal energy simulations were carried out using Ecotect Analysis 2011. The results of the field measurements were compared to those of the simulation. Because the percentage difference (PD) between Ecotect measurements (EM) and field measurements (FM) for both thermal loads and illuminance levels was less than 15%, the simulated model was deemed accurate enough for future investigation. The findings suggest that the simulated model would be sufficient for designers to analyse parameters such as wall to window ratio and shading devices in relation to the building's orientation in order to attain the best possible useable daylight index.

Validation of Daylight Analysis Methodology Using Field Measurements and a Simulation Model - A Case Study of Residential Building in Nagpur | Chapter 2 | New Ideas Concerning Science and Technology Vol. 11

 In terms of lighting rate and health benefits, using natural daylight in the building saves electricity. Increased daylight availability, on the other hand, could result in thermal ingress in hot and dry climate zones. This could lead to excessive energy use. The aim of this paper is to develop a technique that can be used as a pre-design tool for evaluating daylighting and thermal efficiency of spaces inside buildings that designers can use during the design process. The case study is based on the liveable space of a Nagpur dwelling unit. The simulation model was compared to the methodology, which centred on comparing field measurements. This model has been developed to be used for further evaluation of daylight parameters. Field measurements are taken for both daylight and thermal energy levels. Sensors are used to take field measurements, and Ecotect Analysis 2011 software is used to simulate the results. If the percentage difference (PD) between simulation (S) and field measurements (FM) for a given daylight level is less than 15%, the simulated model is considered reliable for further research and parameter evaluation. The results indicate that the simulated model will be sufficient for designers to test the parameters in relation to the building's orientation, allowing for the best possible amount of daylight in the building's interior spaces.
