“…This opening ratio is generally referred to as the 'direct-to-direct transmittance' of the blind [Pfrommer, 1996;EnergyPlus, 2002]. Figure 2 illustrates the case when the opening ratio is greater than zero.…”

“…Pfrommer and EnergyPlus models [Pfrommer, 1996;EnergyPlus, 2002] use slightly different formulations for the direct-to-direct transmittance because they define the slat angle differently. Equation (2) assumes that the slats are flat and that the thickness of the slats is negligible.…”

“…Parmelee and Aubele [Parmalee, 1952] developed two models: one for a specular reflecting surface and one for a diffuse reflecting surface. Pfrommer et al [Pfrommer, 1996] also developed algorithms for both specular and diffuse reflecting surfaces but they combined the algorithms into a single model that can describe surfaces that are neither purely specular nor purely diffuse. The Pfrommer model uses a "shining factor" [Pfrommer, 1996], defined as the ratio between the diffuse-reflected and the total-reflected components, to specify the diffuseness of the blind slat.…”

“…Formulations for specular reflecting surfaces are presented in an analytical form for both Parmelee and Pfrommer model [Parmalee, 1952;Pfrommer, 1996]. A preliminary investigation showed that although Parmelee and Pfrommer models use different formulations, the results predicted by Parmelee's specular reflecting model and Pfrommer's model using a shining factor of zero were exactly the same.…”

EnergyPlus is the DOE's newest building energy simulation engine. It was developed specifically to support the design of low energy building systems. This project focused on developing new low energy building simulation models for EnergyPlus, verifying and validating new and existing EnergyPlus models and transferring the new technology to the private sector. The project focused primarily on geothermal and radiant technologies, which are related by the fact that both are based on hydronic system design.As a result of this project eight peer reviewed journal and conference papers were added to the archival literature and five technical reports were published as M.S. theses and are available in the archival literature. In addition, several reports, including a trombe wall validation report were written for web publication.Thirteen new or significantly enhanced modules were added to the EnergyPlus source code and forty-two new or significantly enhanced sections were added to the EnergyPlus documentation as a result of this work. A low energy design guide was also developed as a pedagogical tool and is available for web publication. Finally several tools including a hybrid ground source heat pump optimization program and a geothermal heat pump parameter estimation tool were developed for research and design and are available for web publication.3 EnergyPlus, the DOE's newest building energy simulation engine, was developed specifically to support the design of low energy building systems. This project focused on enhancements to the EnergyPlus environment related to achieving that goal. Three broad objectives were set forth in the project scope:1. Develop new low energy building simulation models for EnergyPlus. Low temperature radiant, geothermal system models and advanced zonal models were specifically in view.2. Verify and validate new and existing EnergyPlus models.3. Transfer the technology. Develop tools and technical reports to assist in EnergyPlus based design of low energy buildings.The project objectives were met or exceeded in every category as follows:• Eight peer reviewed journal and conference papers were added to the archival literature.• Five technical reports were published as M.S. theses and are available in the archival literature.• Thirteen new or significantly enhanced modules were added to the EnergyPlus source code.• Forty-two new or significantly enhanced sections were added to the EnergyPlus documentation.• A low energy design guide was developed as a pedagogical tool and is available for web publication.• A hybrid ground source heat pump optimization program was developed for research and design and is available for web publication.• A geothermal heat pump parameter estimation tool was developed for research and design and is available for web publication.• A trombe wall validation report was written and is suitable for web publication.A summary of the deliverables associated with each of the three main project objectives is shown below. This is followed by a table showing project t...
