Included in the paper is a description of the software and database platform used in the web application and how this software is attached to the DOE-2 legacy software running on a cluster of servers. This tool will be used by commercial builders in Texas to check code compliance of new commercial construction for specific building types. 2009-07-01T00:00:00Z http://hdl.handle.net/1969.1/94782 Development of a High-Performance Office Building Simulation Model for a Hot and Humid Climate This paper presents the results of implementing 14 high-performance measures in a prototypical office building in a hot and humid climate using the DOE-2 simulation program. The objectives of this research were to discover high-performance measures applicable to office buildings in hot and humid climates and to develop a high-performance (maximum energy-efficient) building model that only uses technologies readily available in the contemporary market. The high-performance model showed 48% total energy savings above the ASHRAE 90.1-1999 code and 61% savings when compared to the calibrated simulation model of the case-study building. The results show that substantial energy savings can be achieved only by using common technologies. 2009-07-01T00:00:00Z http://hdl.handle.net/1969.1/94781 Development of a Web-Based, Code-Compliant 2001 IECC Residential Simulator for Texas This paper describes the development of a web-based, code-compliant 2001 IECC1 residential simulation for Texas. Included in the paper is a description of the software and database platform used in the web application and how this software is attached to the DOE-2 legacy software running on a cluster of servers attached to the web. Additional information is included about how a residence is dynamically updated by the web-page, using macro commands and a flexible yet fixed-schematic input file. This tool is currently in use by builders in Texas to check code compliance of new residential construction. It also calculates NOx, SOx and CO2 emissions reductions from the energy savings of the proposed house for the electric utility associated with the user using the data from the Emissions and Generation Resource Integrated Database (eGRID) provided by U.S. Environmental Protection Agency. 2009-07-01T00:00:00Z http://hdl.handle.net/1969.1/94780 An Improved Procedure for Developing Calibrated Hourly Simulation Models In order to improve upon previous calibration techniques, this paper presents new calibration methods including a temperature bin analysis to improve hourly x-y scatter plots, a 24-hour weatherdaytype bin analysis to allow for the evaluation of hourly temperature and schedule dependent comparisons, and a 52-week bin analysis to facilitate the evaluation of long-term trends. In addition, architectural rendering is suggested as a means of verifying the building envelope dimensions and external shading placement. Several statistical methods are also reviewed to evaluate the goodness-offit including percent difference calculations, mean bias error (MBE), and the coefficient of variation of the root mean squared error (CV(RMSE)). The procedures are applied to a case study building located in Washington, D.C. Nine months of hourly whole-building electricity data and site-specific weather data were measured and used with the DOE- 2. ID building simulation program to test the new techniques. Use of the new calibration procedures were able to produce an hourly MBE of -0.7% and a CV(RMSE) of 23.1% which compare favorably with the most accurate hourly neural network models. 1995-08-01T00:00:00Z
