Building Energy Simulation Test for Existing Homes - Bog - Paperback

Building Energy Simulation Test for Existing Homes - Bog - Paperback

The U.S. Department of Energy tasked NREL to develop a process for testing the reliability of models that predict retrofit energy savings, including their associated calibration methods. DOE asked NREL to conduct the work in phases so that a test procedure would be ready should DOE need it to meet legislative requirements related to residential retrofits in FY 2010. This report documents the initial 'Phase 1' test procedure.

Spirometry Quality Assurance - Common Errors and Their Impact on Test Results - Bog - Paperback

Spirometry Quality Assurance - Common Errors and Their Impact on Test Results - Bog - Paperback

Spirometry is the most common pulmonary function test (PFT) and it plays a central role in occupational respiratory disease surveillance programs. Accurate spirometry testing, interpretation, and follow-up are critical to effective screening and surveillance of workers exposed to respiratory hazards and to the management of patients in the clinical setting. Spirometry quality assurance includes examination of test values and evaluation of both the volume-time and flow-volume curves for evidence of..

International Energy Agency Building Energy Simulation Test and Diagnostic Method for Heating, Ventilating, and Air-Conditioning Equipment Models (HVA

International Energy Agency Building Energy Simulation Test and Diagnostic Method for Heating, Ventilating, and Air-Conditioning Equipment Models (HVA

This report documents an additional set of mechanical system test cases that are planned for inclusion in ANSI/ASHRAE STANDARD 140. The cases test a program's modeling capabilities on the working-fluid side of the coil, but in an hourly dynamic context over an expanded range of performance conditions. These cases help to scale the significance of disagreements that are less obvious in the steady-state cases. The report is Vol. 2 of HVAC BESTEST Volume 1. Volume 1 was limited to steady-state test..

Missile Defense - Review of Allegations about an Early National Missile Defense Flight Test: Gao-02-125 - Bog - Paperback

Missile Defense - Review of Allegations about an Early National Missile Defense Flight Test: Gao-02-125 - Bog - Paperback

The Department of Defense (DOD) awarded contracts to three companies in 1990 to develop and test exoatmospheric kill vehicles. One of the contractors--Boeing North American--subcontracted with TRW to develop software for the kill vehicle. In 1998, Boeing became the Lead System Integrator for the National Missile Defense Program and chose Raytheon as the primary kill vehicle developer. Boeing and TRW reported that the June 1997 flight test achieved its primary objectives but detected some sensor abnormalities...

Test and Evaluation - Dod Has Been Slow in Improving Testing of Software-Intensive Systems: Nsiad-93-198 - Bog - Paperback

GAO reviewed the Department of Defense's (DOD) efforts to improve its software acquisition processes and test and evaluation of software-intensive systems, focusing on: (1) how software-related problems affect defense acquisition programs during operational test and evaluation (OT&E); and (2) barriers that limit OT&E effectiveness. GAO found that: (1) DOD software-intensive systems often fail to meet their performance expectations, experience cost overruns and schedule delays, and are not ready for..
