- Description
- The Naval Surface Warfare Center, Dahlgren Division (NSWCDD) is soliciting sources for ideas and concepts to design and develop technologies or techniques that hold the potential to convert existing building geometry (e.g., walls, doors, and windows), Heating, Ventilation, and Air Conditioning (HVAC) geometry (e.g., duct sizes, locations, and types), and HVAC control information (e.g., fan CFM, airflows, and pressure drops) into the Industry Foundation Classes (IFC) 2x model architecture. Potential solutions can input converted data into the IFC 2x model either by modifying existing or creating new extension modules. NSWCDD also solicits ideas and concepts to convert IFC files to a specified project zonal model file. The goal is to automatically convert existing building and HVAC information obtained from blueprints and electronic drawing programs (i.e., AutoCAD, Microstation, and others) into an IFC module or module extensions; then use the IFC data to generate the required information to support the zonal airflow modeling of the described building. Sources may respond with solutions for converting the existing formats to the IFC 2x model and extensions, IFC output files to the zonal model file, or both. Building and HVAC geometry currently exists in a variety of hard (i.e., blueprints) and soft forms (i.e., CAD files). These various forms present a significant challenge to the timely use of this information for computer modeling purposes. The desired solution will translate this information into a single format usable in a zonal model currently under development. Current processes require individuals to physically extract relevant data (e.g., geometry data and control information) from existing drawings and input the relevant information into the zonal model. This process is labor-demanding, time intensive, and presents many opportunities for inaccuracies. NSWCDD desires a process that automates the extraction and conversion processes from a variety of CAD systems to the IFC 2x model and extensions with high accuracy during translation. The IFC 2x model is a product of the International Alliance for Interoperability (IAI). IAI developed the 2x model to provide for the exchange and sharing of information between different software applications either of the same or different types. To learn more about the IFC 2x model, visit the IAI website at http://www.iai-international.org/iai_international/. Also, IFC 2x documentation can be found at http://cig.bre.co.uk/iai_international/Technical_Documents/iai_documents.html For this announcement, building geometry includes those components that define the sha pe, volume, and openings associated with a stationary structure. Items to consider are, but not limited to, the placement, size, and type of exterior and interior windows, doors, walls, and ceilings including suspended or false types. Also, solutions need to consider concepts for leakage values for all exterior and interior openings (e.g., windows, doors, and suspended ceilings) associated with the building. HVAC geometry includes those components that define the shape, volume, and openings associated with the HVAC system of a stationary structure. Items to consider are, but not limited to, duct sizes, duct types, duct location and routing, plenum size, types and location of intakes, exhausts, and dampers. HVAC control includes those components that regulate temperature and airflow associated with a stationary structure. Items to consider are, but not limited to, fan speeds, flow rates, damper closing and opening times, intake and exhaust flows, pressure information, sensor types, and start and stop trip points. Also, consider how the HVAC system responds to actions based on sensor trips and inputs (e.g., dampers close, exhaust fan starts, heater starts or stops). NSWCDD also seeks approaches to generate IFC outputs into a government defined format file for use in a zonal model currently under development. NSWCDD is using the CONTAMW 2.0 airflow modeling and simulation tool as the core for the zonal model under development. CONTAMW 2.0 is a multizone indoor air quality and ventilation analysis computer program developed by the National Institute of Standards and Technology (NIST). CONTAMW 2.0 can predict airflows, contaminant concentrations, and personal exposure to airborne contaminants for eventual risk assessment. CONTAMW 2.0 i s usable for a variety of applications. CONTAMW 2.0 can calculate building airflows to assess the adequacy of ventilation rates in a building and to estimate the impact of envelope air tightening efforts on infiltration rates. The prediction of contaminant concentrations can determine the indoor air quality performance of a building before it is constructed and occupied, to investigate the impacts of various design decisions related to ventilation system design and building material selection, and to assess the indoor air quality performance of an existing building. Predicted contaminant concentrations can help estimate personal exposure based on occupancy patterns in the building. Comparison of exposure estimates for different assumptions of ventilation rates and source strengths is possible. To learn more about CONTAMW, visit the NIST website at http://www.bfrl.nist.gov/ IAQanalysis/CONTAMWdesc.htm Submission of Responses: Sources may respond with conversion solutions from existing formats to IFC, IFC output files to the zonal model file, or both. In all cases, sources must describe how their technology or technique will improve the current process to convert existing hard and soft formats into the IFC 2x model architecture format and/or to convert the IFC format to the specified project zonal model file. Sources shall identify any experience in performing the conversion processes described by the paper submitted for this requirement. Submissions in response to this announcement shall a white paper of no more than 10 pages (excluding cover page). Papers shall be unclassified. Sources shall clearly identify all proprietary portions of the paper and NSWCDD will treat these in the strictest confidence. NSWCDD will accept papers from date of issuance for this announcement through 30 April 2003. Sources may submit papers any time during this period; however, an initial review of papers will start 30 days after issuance of this announcement. Submit papers to sd13@nswc.navy.mil. The Government does not intend to make an award on the basis of papers submitted for this sources sought advertisement. This announcement will be available on the World Wide Web at http://www.nswc.navy.mil/supply. All submissions must reference Solicitation Number N00178-03-Q-3009 and provide the Offeror's name/address/point of contact/phone number/email address.
