Hi Dilip, Simulating Elevator is one of the most complicated model mechanism depends on how many floors in simulation. There are many ways to create elevator using different compound objects and conditions. For basic simulation, I prefer 2 floors operation elevator and the step below... Entities from Lower Level to Upper Level 1. At the Lower Level create a Waiting Zone for boarding area in front of the elevator. 2. Cover that Waiting Zone with Direction Modifier with filter boarding entities and a boarding control profile (can be event profile or availability profile) send entities to a Delay Point (you can set the maximum capacity and delay forever) inside the elevator Lower Level. 3. Create another Direction Modifier cover boarding area with filter boarding entities and a send back profile (after boarding time-door close) send missed boarding entities back to the Waiting Zone boarding area. 4. Inside the Lower Level - elevator, create a Direction Modifier cover the elevator area with a profile sending entities to Level Exit (Lower Level) inside the elevator. 5. Entities will send to Level Entrance (Upper Level) and send to Waiting Zone inside elevator Upper level. 6. Create a Direction Modifier cover that Waiting Zone inside elevator Upper level and link entities to target outside. Entities from Upper Level to Lower Level 1. At the Upper Level create a Waiting Zone for boarding area in front of the elevator. 2. Cover that Waiting Zone with Direction Modifier with filter boarding entities and a boarding control profile (can be event profile or availability profile) send entities to a Delay Point (you can set the maximum capacity and delay forever) inside the elevator Upper Level. 3. Create another Direction Modifier cover boarding area with filter boarding entities and a send back profile (after boarding time-door close) send missed boarding entities back to the Waiting Zone boarding area. 4. Inside the Upper Level - elevator, create a Direction Modifier cover the elevator area with filter and a profile sending entities to Level Exit (Upper Level) inside the elevator. 5. Entities will send to Level Entrance (Lower Level) and send to Waiting Zone inside elevator Lower level. 6. Create a Direction Modifier cover that Waiting Zone inside elevator Lower level and link entities to target outside. I also insert the sample LGM model for various elevator mechanism for the reference. https://bentley-my.sharepoint.com/:u:/r/personal/saton_sirivorapituk_bentley_com/Documents/Legion%20SpaceWorks-2%20level%20fixed%20cycle%20lift%20v2%20(1).lgm?csf=1&web=1&e=qKCtri Hope this help Saton

Forum Post: OpenBuildings Designer - ausgeblendetes zwischengespeichertes Element wieder einblenden
Hallo Zusammen, ich habe zum OBD Update 6 eine neue Frage. Es geht um das Wiedereinblenden eines Elements welches zuvor mit der Funktion "Zwischengespeichertes Element ausblenden" ausgeblendet wurde. Die einziege Möglichkeit die ich bis jetzt gefunden habe ist, die Sichtbaren Kannten wieder von "Zwischengespeichert/Manuell" auf "Dynamisch" und dann wieder zurück auf "Zwischengespeichert" zu schalten. Dann sind aber alle Elemente wieder Sichtbar und man kann von neuem beginnen diese auszuschalten. Gibt es eine Möglichkeit nur ein bestimmtes Element wieder einzublenden? Hier ein Beispiel. Im ersten Bild sind noch beide Türen sichtbar. Im zweiten Bild wird die eine Tür mit Rechtsklick ausgeblendet. Bild 3 - Hier ist die linke Türaufschlagsymbolik nicht mehr zu sehen. Vielleicht hat ja jemand eine Idee oder eine Lösung. Gruß Viktor

Forum Post: Alternatives to CAD Import
Hi all, Some other pedestrian simulation software, instead of using CAD, allows for a PDF import which is then set as the background. The floor layout can then be drawn with the software's tool. Pathfinder is an example of software that uses image files as opposed to CAD. Anyone know if LEGION has a similar alternative to importing a CAD file? Instead, a PDF or Image file is imported as a background and then CAD objects can be drawn over top of the image. Thanks!

Forum Post: RE: Alternatives to CAD Import
Hi Dilip, Thank you for your suggestion, I will raise this issue to our developer. Right now only CAD file ( DWG, DXF, DGN) is necessary for identifying accessible spaces and clear appearance. In case you intend to import PDF or JPG for visual purposes, you can insert them in picture format(jpg, png) later over the AVI recording layout in Simulator but still very restrict to adjust. Hope this help Saton

Forum Post: RE: OBD U6 - Catalog Editor vs Config Dialog
Hi Bob, The three filter variables should not point to the same place, they are specifically designed to point to the three separate configuration levels. Leaving BB_DATASET_WORKSPACE_FILTER and BB_DATASET_WORKSET_FILTER at their default values should work correctly. BB_DATASET_ORGANIZATION_FILTER = $(BHP_DATASET) should point the Catalog Editor UI at your copy of the dataset instead of the C:\ drive version. If you can share your configuration files with us via the SR you filed or use Bentley Configuration Explorer to export a .BCF file we will have a better understanding of your configuration. Please can you show us how you have redirected your configuration to the network, it is quite possible that a variable earlier in the process needs to be set to tidy this all up.

Wiki Page: CIBSE Gain - Solar gains at night
Product(s): OpenBuildings Energy Simulator Version(s): CONNECT Edition Environment: N/A Area: Calculations Subarea: N/A Overview CIBSE Gain results can often display Solar Gains at night. Method The CIBSE Gain calculation considers both an instantaneous solar component and mean solar component . The mean solar component consists of solar gains that are re-radiated from surfaces having being absorbed as gains during the sunshine hours. The Cooling Plant Operation in Building Properties (accessed from project tree as in image below) determines the hours that these gains are considered. Therefore, if you have set your Cooling Plant Operation to 24 hours a day, the gains for each of those hours will be displayed in your results.

Wiki Page: Overview of Calculations in Energy Simulator
Product(s): OpenBuildings Energy Simulator Version(s): CONNECT Edition Environment: N/A Area: Calculations Subarea: N/A Overview The following steady state calculations are available in OpenBuildings Energy Simulator: Method ASHREA 90.1 Assesses building compliance according to 2010, 2007 or 2004 requirements. Provides the minimum requirements for the energy efficient design of buildings except low-rise residential buildings. This includes all new buildings, additions and retrofits. Results given for Summary, Building Envelope, Lighting, Service Water Heating and HVAC. ASHRAE 62.1 2010, 2007 and 2004 are all available. Used to specify the minimum ventilation rates and indoor air quality that will be acceptable to human occupants and are intended to minimize the potential for adverse health effects. The standard applies to new buildings, additions to existing buildings, and retrofits identified in the standard. The standard is intended to be used to guide the improvement of indoor air quality. PartL 2013 For assessing and producing building Compliance documentation and Energy Performance Certificates, using the SBEM calculation engine. England, Wales, Scotland and Jersey all available. Heat Loss ASHRAE Heat Loss - Used to display results from the ASHRAE Heat Loss calculation in several report formats. Losses for individual room surfaces are detailed on the full report. Total losses for rooms can be viewed in the summary report. Results can also be viewed graphically on the Graph tab. CIBSE Simple - Used to display results from the CIBSE heat loss calculation conducted using the Simple Model steady state heat loss model. The Simple Model assumes that the heat transfer coefficients can be lumped together and assumes rooms are cubic when considering radiative heat exchange. The mean radiant temperature is assumed to be the average of the internal surface temperatures. Other approximations are made to heat transfer processes, which enable all heat flows to be considered as being to the air point or the environmental point. The heat transfer relationship between these two points is then established for the room, enabling heat losses to be computed. CIBSE Basic - Used to display results from the CIBSE heat loss calculation conducted using the Basic Model steady state heat loss model. The Basic Model, also referred to as the complex model, involves carrying out a rigorous heat balance for the room, considering convective and radiative heat transfer separately. The complex heat loss model calculation results are often different from those obtained using the simple heat loss model. It is considered more accurate results because it is based on a more accurate analysis of room heat transfer, with fewer approximations. ASHRAE RTS Used to display results from the ASHRAE RTS (Radiant Time Series) calculation. Hourly total loads are provided with breakdown of loads through fabric, glazing, infiltration, internal gains. Gain through each surface can be viewed. Total Peak Room loads can be viewed in the Summary report. CIBSE Heat Gain Calculates heat gains using the method described in Section A5 of CIBSE (UK) Guide. Peak room loads and a breakdown for Solar, Fabric, Convective, Latent and Casual loads are produced ( info here ), along with the resultant A ir Flow Rates required to maintain your design temperatures in each room. CIBSE Maxi Gain This program finds the peak heat gain month for all included rooms and the coincident peak month for the group of rooms. Computes heat gains using the CIBSE method for each month to find the peak month. Summer Summertime temperatures in rooms are computed for your design day using the method described in CIBSE Guide Section A5. Hourly outside temperatures, time of peak, and peak internal temperatures are displayed. Air Flow Calculates the total air flow to all the rooms included, assuming either a constant volume or VAV system. Results are given for sensible and latent gains , together with the computed supply air temperature for each room. To examine the formulae and calculation methods behind each of the above, you can directly examine results as show in this article.

Wiki Page: Fresh Air Loads
Product(s): OpenBuildings Energy Simulator Version(s): CONNECT Edition Environment: N/A Area: Calculations Subarea: N/A Overview The CIBSE Gain calculation in OpenBuildings Energy Simulator allows for the introduction of fresh air or conditioned air. These settings can be found in HVAC Manager as below, under the HVAC System "SteadyState, heat gain and loss" . Method The available options are: No additional fresh air Fresh air introduced locally to rooms Conditioned primary fresh air Fresh air from central plant with conditioned air This option is for conditioning the room locally be means of fan coil units. Fresh air is not being introduced directly into the room, or at the main plant. This option is for local conditioning via fan coils and the introduction of untreated air into the room. The untreated air could be introduced into the fan coil unit, directly into the room, or ceiling void. This option is for local cooling in the room (fan coil units) but also have a fresh air requirement that is being managed by central plant. The temperature of the primary fresh air must be specified. You can also set a humidity control for the primary fresh air if desired. The central plant will then be modeled based on the heating/cooling and humidify/dehumidify parameters. When considering this option, individual room load results will be affected as the cooling on the primary fresh air will be considered. The plant results will display the fresh air conditioning loads. This option is for all the conditioning at central plant with no local cooling. This could either be by recirculation or a full fresh air system. The illustration shows a recirculation system where primary fresh air is mixed with recirculation air then cooled to the defined supply temperature before being introduced to the room. With this option, room loads will not be affected as there is no requirement for local conditioning. The total plant loads will increase to indicate the fresh air load being handled.
