2 The Apache view is a view within the Virtual Environment s Thermal is the name given to the thermal analysis programs in the VirtualEnvironment. The Apache view provides facilities for: Preparation of input data for the thermal analysis programsApacheCalc, ASHRAE Loads andApacheSim Calculations and simulations using ApacheSim, ApacheHVAC,MacroFlo, ApacheCalc, and ASHRAE LoadsThe preparation of thermal input data consists of three main tasks: Specification of building location and weather data Specification of building element data (properties of the building fabric) Specification of room data (conditions in each room)The interfaces to the thermal analysis programs provide facilities for: Setting up the calculations and simulations Specifying the results to be of the Apache ViewTo put the Apache view in context, it is useful to examine the steps involved increating a thermal model and running the thermal analysis programs. Thisoutline is intended as a Guide . Many of the steps may be interchanged and dataof all types may be edited at any of building the Virtual the ModelBuilder Category and create the building geometry this phase you may find it helpful to use Templates.

3 Templatescontain collections of data for thermal and other applications, and arecreated using the Template Manager. When a template is set as theactivetemplate, its data is automatically assigned to rooms or elements as they EnvironmentPage5of68 Assignment of Apache thermal the Thermal the Apache the APlocate utility to define site location and weather data (for thermaland solar shading calculations). the utility APcdb to define constructions to building elements as the utility APpro to define operational the characteristics of the building s HVAC systems using ApacheSystems and assign systems to each room, assign Room Data to specify heating and cooling, internalgains and Room Thermal Templates to facilitate the previous two of other thermal and solar dataAt this stage (or at any suitable time) you may wish to leave the Apache view tocarry out the following additional the MacroFlo view set up opening air flow characteristics for theMacroFlo simulation the ApacheHVAC view set up HVAC system data for theApacheHVAC simulation the SunCast view of the Solar Category perform solar analysis and results the Apache view , perform either of the following analyses: Industry-standard thermal calculations (ApacheCalc, ASHRAEL oads & related programs) Dynamic simulation (ApacheSim & related programs) results from the thermal analyses using.

4 Vista-a view for displaying and exporting ApacheCalc, ASHRAEL oads and ApacheSim of Apache view Interface FeaturesThe Apache view consists of the following interface features:Virtual Environment menu barPage6of68 These menus provide functions used throughout the Virtual refer to theVirtual EnvironmentUser Guide for further menu barThese pull-down menus provide functions specific to the Apache edit toolbarThese icons provide a quick route to functions on the Apache menu workspaceThis displays the model geometry and provides a graphical means of selectinggeometrical view toolbarThis provides functions for manipulating the view of the geometrical BrowserPage7of68 This list of rooms, opening up to display surfaces and openings in those rooms,provides an alternative way to viewand select geometrical Group toolsThese tools allow the creation, application and selection of Room GroupingSchemes. See the ModelIT user Guide for further analysis buttonsThese buttons invoke the thermal analysis programs CIBSE Loads, ASHRAEL oads and ApacheSim, and Batch the Loads Methodology on the Apache view Settings menu is set toASHRAE, CIBSE Loads is replaced by ASHRAE tools for model viewing and interrogationBefore using the Apache view you should familiarise yourself with the followingtools, which provide the means for navigating around the model to view and setroom and building element attributes: The Virtual Environment menu bar The model workspace The model browser The model view toolbarIn particular, you should be familiar with the following procedures described inthe ModelIT user Guide : Selecting a view of the model workspace using the followingbuttons on the modelview toolbar:Fit viewZoom windowZoom inZoom outPanZoom previousZoom nextView axis (Plan, Right, Left, Front, Back, Axon.)

5 Set axonometric rotationRotate view Selecting a single room or a set of rooms by clicking in the modelworkspace. Selecting a single room or a set of rooms by clicking in the modelbrowser. Panning and zooming the model image. Moving between the following model decomposition levels using theup and down arrows on the view toolbar (or by double-clicking on aroom or surface): Model level Space level (only surface mode applies in the Apache view ) Surface level (opening or adjacency mode) Moving between model decomposition levels by clicking in themodel and Weather DataThe external climate is an important driving force affecting thermal conditions ina building. This data is specified in the program programs CIBSE Loads (or its ASHRAE counterpart, ASHRAE Loads) andApacheSim have different requirements for weather data. APlocate deals withboth types of also sets the building location and information on the setting of clocks,which is important in calculations of solar may be invoked from either the Apache menu bar or the refer to theAPlocateUser Guide for further information on this Element are building elements?

6 Abuilding element(often shortened to element) is a component of the buildingsuch as a wall, ceiling, floor or window. Forconvenience, building elements aredivided into categories such as External wall , Internal glazing , etc. Where aroom surface has multiple adjacencies, each adjacency is treated as a separatebuilding kinds of data need to be set for building elements in the Apache view :construction data describing the element s thermal properties, and adjacencydata describing its thermal boundary conditions. Construction data needs to beset for all elements. Adjacency data is set automatically as a function of buildinggeometry, and need only be edited in special typesAconstruction type(often shortened to construction) is a type of buildingelement in the context of Apache thermal analysis. It consists ofa layer-by-layerdescription of the element s thermophysical properties, together with other datasuch as surface solar absorptivity and emissivity. Construction types arecreated and edited in the program construction type attribute for a building elementEvery building element has an attribute specifying its construction type.

7 Whenthe element is created in ModelIT, its construction type is set by the activeApache Constructions Template. This setting can later be changed using toolsprovidedin the Apache view . The construction type attribute for an elementconsists of a pointer to one of the construction types defined in APcdb. Thismeans that if the construction type data is edited in APcdb, the changeimmediately and automatically takes effect for all elements to which thatconstruction type is the construction typeThe mechanism for changing the construction types of building elements is a building element or a set of building elements (this is calledtheselection set) the selected elements, replace all instances of one construction typewith another construction typeThe first operation may be done in various ways depending on the selection setrequired (see Selecting building elements for construction type editing ).Page12of68 For the second operation the usual method is to use the function Edit selectionset constructions (see Changing the construction type for selected elements ).

8 An alternative method for individual elements is to use the Query same mechanisms may be used to inspect the construction type ofelements without changing building elements for construction type editingThere are several ways to select a set of building elements in the Apache model levelAt the model level of decomposition you may select a single room or a set ofrooms by clicking in the model workspace or the model browser. For thepurposes of construction type setting, this selects all the elements contained inthose space levelAt the space level of decomposition (surface mode applies here) you may selecta room surface. For the purposes of construction type setting, this selects all theelements contained in that surface level (opening mode)At the surface level ofdecomposition (opening mode) you may select a singleopening or a set of surface level (adjacency mode)At the surface level of decomposition (adjacency mode) you may select a the construction type for selected elementsAfter you have selected a set of building elements you can change (or simplyinspect) their construction types by clicking on the icon Edit selection setconstructions on the Edit selection set constructionsdialog(space level shown)On the left of thedialoga graphic of the selection set is shown.

9 At model andspace level, the graphic uses the same view rotation as the active modelwindow. It is usually easier to see the various elements if you select anAxonometric view in the active model window before using the Edit selectionset constructions more than one element category is represented in the selection set it is firstnecessary to select one of these categories from the list headed Selectcategory . Any edits willbe applied only to elements in the selected the heading Construction Type you will see a list of the constructiontypes currently assigned to the selected elements. By clicking on eachconstruction type in turn you will be able to identify the elements where theconstruction is used. These elements are highlighted on the any stage in this inspection process you may replace all the highlightedinstances of the selected construction type with another construction type. Todo this, click on the desired replacement construction type in the list headed Possible replacement construction types , and then click on you need to create or modify construction types during this process you canrun APcdb by clicking on the dataAdjacency data for a building element describes what lies on the other side of it(when viewed from the selected room), and the assumed thermal boundarycondition applying data is set automatically by the program, but in certaincircumstances may be view the adjacency data for a building element, select a room surface byclicking in the model workspace or browser, and change the decompositionmode from opening to adjacency using the selector on the model viewtoolbar.

10 If the surface is adjacent to two or more spaces (including the exteriorspace), you will need to identify, by pointing and clicking, which adjacency youwish to selected an adjacency, click on the Query icon on the Apache toolbar todisplay the adjacency the adjacent space, the area of the element, the ConstructionType (which may be changed here) and the Adjacent Adjacent Condition is set initially depending on the category of element:Category of elementAdjacent ConditionExternal wall or roofOutside airPartition wall or intermediate floor/ceilingInternal partitionGround floor or exposed floorOutside air with offset temp. 0In all cases except partition walland intermediate floor/ceiling, the AdjacencyCondition may be edited. Possible Adjacency Conditions are: Outside air Outside air with offset temperature Temperature from profileOutside airis air with offset temperaturesets thetemperature on the far side of thewall to the outside air temperature plus a constant offset. Enter the value of theoffset in the Temperature Offset box.
