DElight: A Daylighting and Electric Lighting Simulation Engine

An eight-page building simulation paper. DElight is a simulation engine for daylight and electric lighting system analysis in buildings. DElight calculates interior illuminance levels from daylight, and the subsequent contribution required from electric lighting to meet a desired interior illuminance. DElight has been specifically designed to integrate with a building thermal simulation on a time-step basis, for whole-building analysis. This paper describes the simulation methods used in DElight and some of the key details of software implementation. Read More

Effects of External Shading Devices on Daylighting and Natural Ventilation

An eight-page building simulation paper. External shading devices have been utilized very extensively in residential buildings in the tropics to reduce the amount of solar radiation entering into the buildings. However, this will affect the availability of daylight for interior lighting as well as natural ventilation for passive cooling and thermal comfort. This paper discusses the impacts of six different types of external shading device on a residential building in Singapore. The investigation was carried out via the use of LIGHTSCAPE for daylighting simulations and PHOENICS CFD simulations for natural ventilation. From the series of parametric studies, the design of external shading devices to optimize daylighting and natural ventilation performance is developed. The interactions and the inter-relationship between daylighting and natural ventilation simulations that could affect the simulation results were also discussed. Lastly an actual field measurement was also conducted, which serves to provide data for the validation of simulation output. Refers to specific software tools that may not be available. Read More

Experience Testing EnergyPlus with the IEA HVAC BESTEST E100-E200 Series

An eight-page building simulation paper. The EnergyPlus building energy simulation software has been tested using the IEA HVAC BESTEST E100-E200 series of tests. The Volume 1 final report for the International Energy Agency (IEA) Building Energy Simulation Test and Diagnostic Method for Heating, Ventilating, and Air-Conditioning Equipment Models (HVAC BESTEST), was recently published in January 2002. HVAC BESTEST is a series of steady-state tests for a single-zone DX cooling system. Cases range from dry to wet coil, low to high part load, and low to high temperatures. This published test suite includes three sets of analytical solutions and results from several other simulation programs for comparison. Read More

Use of Simulation in the Design of a Large Naturally Ventilated Commercial Office Building

An eight-page building simulation paper. The design for the new Federal Building for San Francisco includes an office tower that is to be naturally ventilated. The EnergyPlus thermal simulation program was used to evaluate different ventilations strategies for space cooling and rationalize the design of the facade. The strategies include ventilation driven by different combination s of wind, internal stack and external stack. The simulation results indicate that wind-driven ventilation can maintain adequate comfort even during hot periods. Read More

WIS: The European Tool to Calculate Thermal and Solar Properties of Windows and Window Components

An eight-page building simulation paper. WIS is a software tool, developed in a European research project, for the calculation of the thermal and solar properties of commercial and innovative window systems on the basis of known component properties and thermal and solar/optical interactions between the components. WIS is available without charge and its further development and technical support is guided by the European network “WinDat”, consisting of major research institutes and manufacturers of window components (glazings, solar shading, …). One of the features of the software tool is the combination of glazings and shading devices, with the option of free or forced air circulation between the components. This makes the tool particularly suited to calculate the thermal and solar performance of complex windows and active facades. The paper describes the main features of WIS and the activities in WinDat. Specificly highlighted is the modelling of the thermal/solar properties of solar shading devices and their interaction with the other components in the window.

Simulation and Evaluation of Markets for Building Cooling Heating and Power Applications in the U.S.

An eight-page building simulation paper. A two-level analysis was used to study the economic potential of implementing Building Cooling, Heating and Power (BCHP) technologies in the U.S. A simplified level allowed limiting the full evaluation to seven major metropolitan areas and seven typical service applications in three basic configurations. The more rigorous level of simulation involved studies of 147 cases and involved software developed at GTI. This software employed DOE21.E computational engine to generate 8760 hourly building load profiles. Also, calculated were the energy consumption and costs as based on the specific electric and gas rate structures and equipment characteristics. The results rate the three types of systems, i.e. the power generation without heat recovery, (DG), power generation with heath recovery to heating and domestic hot water, (CHP), and power generation with heat recovery for heating, domestic hot water and absorption cooling, (BCHP).

Simulation Support for the Formulation of Domestic Sector Upgrading Strategies

An eight-page building simulation paper. This paper describes the application of a building simulation program to construct a decision-support tool for use by policy makers addressing the needs of the Scottish domestic housing sector. The process of tool formulation is described and an example given of its use to identify best-value retrofit options while taking factors such as future climate change and improved standard of living into consideration. It is argued that the process of tool formation renders it applicable to the cumulative roll-out of upgrade measures in the long term, both within and outwith the UK. Read More
