What's New in HAP v4.1

HAP 4.1 was released in May 2002. This section is intended for readers who are familiar with HAP v4.0, System Design Load v4.0 or earlier versions of these programs and are interested in learning about new features in HAP v4.1 and changes made to features that existed in prior versions of HAP. Noteworthy new features and feature changes are listed below for the major functional areas of the program.

  • General:
    • The program has been expanded to include features for estimating annual energy use and energy cost for buildings. These building energy analysis features utilize dynamic 8,760-hour simulation calculations.
  • Weather:
    • A fourth tab has been added to the Weather Form. The ¿Simulation¿ tab is used to specify the simulation weather data used for an energy analysis and to define the operating calendar for the energy simulation. In addition, tabular and graphical report options have been added for simulation weather data. Finally, design weather data was added for a number of new cities.
  • Air Systems:
    • Air system features have been expanded to include equipment performance inputs for packaged rooftop units, packaged vertical units, split DX AHUs, split and packaged DX fan coils, and water source heat pumps. This performance data is used in energy simulations. System Design calculations and reports have also been revised.
  • Plants:
    • The plant inputs have been expanded to include data describing the configuration and control of chilled water, hot water and steam plants. Features are also provided for modeling complex pumping systems such as primary/secondary and primary variable speed. These new features are used in energy simulations for the plant.
  • Buildings:
    • This is a new data category in the program and is used for energy analysis work.
  • Schedules:
    • The assignments table has been expanded for use in energy analysis applications.
  • Chillers:
    • This is a new data category in the program and is used in energy analysis calculations.
  • Cooling Towers:
    • This is a new data category in the program and is used in energy analysis calculations.
  • Boilers:
    • This is a new data category in the program and is used in energy analysis calculations.
  • Electric Rates and Fuel Rates:
    • These are two new data categories in the program and are used in energy analysis calculations.
  • Reports:
    • Key new report engine features have been added.
General
  • Simulation Features. The program has been expanded to estimate annual energy use and energy costs for buildings. Building energy analysis involves simulating building thermal performance and the operation of HVAC and non-HVAC equipment for all 8,760 hours in a year. These simulations produce energy use profiles which are used together with utility rate structures to calculate the costs of energy use. Energy use and cost can be compared for alternate design scenarios or energy conservation measures to determine the optimum design.
  • Operating Mode Selection. The options dialog (see View Menu, Options item) provides a feature for switching the program between full HAP and HAP System Design mode. Full HAP exposes all the features for both system design and energy analysis. HAP System Design mode hides those features used for energy analysis. This option is only available in the full edition of HAP. It is sometimes helpful when using the program for system design as it hides features not needed for the system design work.
  • Data Retrieval From Previous Versions. Two options are offered for retrieving data from previous versions of HAP. Both are found on the Project Menu. One option is used to retrieve HAP v3.2 data and convert it to a format compatible with v4.1. The other is used to retrieve HAP v4.0 data.
  • Cosmetic Changes to Main Window. The right-hand panel on the main program window now lists data in alphabetical order when using the List or Details modes for this panel. Previously data was sorted by index number and this was inconvenient for many users trying to organize their data.
  • Update to Installation Software. The installation software has been reconfigured to avoid the Windows 98 installation problem that caused the "missing application or project-related data" and "this application is not registered with Configuration Services" errors. These errors should no longer occur.
  • Improved Access to Help System. The on-line help system for HAP can be launched without running HAP. When the software is installed a Help sub-group will appear beneath the ¿Carrier E-CAT and E20-II Programs¿ group. It contains an item for launching the HAP v4.1 help system directly.
  • Consolidation of File Integrity Verification Reports.The File Integrity Verification Report for HAP v4.1 now lists all files required by both HAP and Configuration Services. This report is used when troubleshooting computer configuration problems. In the past, two separate reports - one for HAP and one for Configuration Services - had to be generated to obtain complete data for files used by HAP. Now only one report needs to be generated.
  • New On-Line Calculator. The new portions of the user interface provide an on-line calculator built into each input item. For example, when entering a pump flow rate you could type 250*2.4= and the result (600) would appear in the input cell. Previously the Windows on-line calculator had to be used to perform this task. Please note that this feature is available in all of the new user interface portions of the program (Plants, Buildings, Chillers, Cooling Towers, Boilers, Electric Rates, Fuel Rates). It will be added to the other portions of the interface in subsequent versions of HAP.

Weather
  • Simulation Tab. A "Simulation" tab has been added to the Weather form. This tab includes inputs used to select simulation weather data for the project, to specify the day of week for January 1st and to designate the calendar of holidays for the simulation year.
  • Simulation Weather Data.Simulation weather data for over 300 cities worldwide is provided on the HAP CD-ROM. Details:
    • All TMY, TRY and Actual Year simulation weather files from the HAP v3.2 weather library are provided with HAP v4.1. Files containing simplified average data that were provided with HAP v3.2 have been omitted.
    • Simulation weather data is provided on the HAP CD-ROM in the Weather folder. This folder contains a series of files, with one for each city. File names indicate the contents (example: USA_ILLINOIS_CHICAGO.HW1).
    • When running HAP, this data can be loaded into a project directly from the HAP CD using the Select City button on the Simulation tab of the Weather form.
    • As an alternative, weather files can be copied from the HAP CD to your hard disk prior to running HAP. We recommend copying files to the E20-IIWEATHER folder on the drive containing HAP. However, this is not a requirement. It will only make accessing the data easier. When you press the Select City button, the program first looks in E20-IIWEATHER for available files.
  • Simulation Weather Reports. Reports for simulation weather data have been added. These reports can be generated using the Print/View Input Data option for Weather. The reports include:
    • Simulation Weather Statistics - A tabular report that summarizes the maximum, minimum and average temperatures and solar radiation values for each month.
    • Simulation Weather Profiles - A tabular report that lists the hourly temperature, humidity and solar radiation profiles for a chosen range of days during the year.
    • Simulation Temperature Profiles - A graphical report showing profiles of hourly temperature and humidity for a chosen range of days during the year.
    • Simulation Solar Profiles - A graphical report showing profiles of hourly solar radiation data for a chosen range of days during the year.
  • Design Weather Data for Caribbean and Central American Cities. In response to customer requests, design weather data has been added for all Caribbean and Central American cities (plus Bermuda) listed in the ASHRAE Handbook of Fundamentals. These cities include:
    • Nassau, Bahamas
    • Hamilton, Bermuda
    • Kingston, Jamaica
    • Montego Bay, Jamaica
    • Panama City, Panama
    • Tocumen, Panama
  • Revised Design Weather Data for Venezuela. Data for Maiquetia, Venezuela was revised. The ASHRAE Handbook lists the city name for this data as Caracas, Venezuela. However, the data is for the Caracas Airport which is located in Maiquetia at an elevation of 157 ft. Caracas is at an elevation of approximately 3100 ft. The city name was revised to eliminate any confusion. The elevation was corrected to 157 ft.

    In addition, data for Caracas was added. This data was obtained by Carrier Inter-America staff via local sources.
  • Design Weather Data for Chinese Cities. Data for cities in the People's Republic of China has been updated. HAP v4.0 contained data for 5 Chinese cities, with data obtained from the 1997 ASHRAE Handbook of Fundamentals. This data has been replaced with new data for 47 cities obtained from the Chinese design standard GBJ19-87.

Air Systems
  • Air System Inputs
    • Inputs Expanded to Include Equipment Performance Data.
      • System inputs have been expanded to include performance data for packaged rooftops, packaged vertical units, split DX AHUs, split and packaged DX fan coils, packaged terminal heat pumps and water source heat pumps. These inputs appear on a new "Equipment Data" tab on the System form. This data is required for energy simulations.
      • Example: A single-zone constant volume packaged rooftop system is being defined. The system uses gas heat. As a result, extra inputs for the DX central cooling unit and the gas combustion heating unit will appear on the Equipment Data tab. Inputs for the cooling unit include items such as design OADB, gross cooling capacity at design, and compressor + outdoor fan input kW at design. Inputs for the heating unit include gross capacity and the average combustion efficiency.
        When an energy analysis includes packaged or split equipment, calculations for DX cooling, heat pump, combustion heating and electric heating energy use are performed as part of the air system simulation. Also, all calculations for electric resistance heating are done in the air system simulation. Previously, in HAP v3.2, these calculations were part of the plant simulation.
      • When an energy analysis includes packaged or split equipment, calculations for DX cooling, heat pump, combustion heating and electric heating energy use are performed as part of the air system simulation. Also, all calculations for electric resistance heating are done in the air system simulation. Previously, in HAP v3.2, these calculations were part of the plant simulation.
    • More Efficient Modeling of Terminal Units.
      • When performing system design calculations or energy simulations for packaged DX fan coils, split DX fan coils, terminal heat pumps and water source heat pumps, the collection of terminal units can be modeled as part of one air system.
      • For example, if you are studying a 50-zone system where each zone contains a water source heat pump, you only need to define one air system with 50 zones. The program will perform sizing calculations for all 50 heat pumps within the system. It will also perform energy simulations for all 50 heat pumps in the system.
      • Previously, in HAP v3.2, system design calculations could be performed this way, but energy simulations could not. For energy simulations, each zone had to be defined as a separate air system in order to keep loads separate and properly calculate compressor performance for each terminal unit or heat pump. In HAP v4.1 this requirement has been eliminated. The program is able to properly simulate each terminal unit or heat pump's operation within a system. This makes energy studies for these types of equipment much easier.
    • Revised Sort Order for Space Selection
      • On the Zone Components tab, Space Assignments data view, the list of spaces in the project has been revised to display in alphabetical order. This sort order now matches the order shown on the main program window for HAP. It also makes it easier to locate spaces in projects containing large numbers of spaces.
  • System Simulations.
    • Energy Simulation.
      • HAP v4.1 adds the ability to run hour-by-hour simulations of air system operation to estimate energy use and energy cost. Simulations track cooling loads, heating loads, and energy use by system components. These components include fans, DX cooling equipment, heat pumps, combustion heating units, electric resistance heaters and self-contained humidifiers. In the case of water-cooled vertical packaged units and water source heat pumps, energy use data also includes water pumps, cooling towers and auxiliary boilers.
    • Simulation Reports
      • Results from energy simulations are provided on a variety of reports. These reports provide system performance data on an hourly, daily, monthly and annual basis in both tabular and graphical formats. In addition zone temperature statistics and data on hours of operation and unmet loads are also reported. A feature is provided for exporting simulation results in a text format convenient for import into spreadsheets.
    • Humidifier Performance
      • Simulations report humidification loads and the energy consequences of providing humidification. Options are provided for self-contained electric, gas and propane humidifiers. In these cases humidification energy is reported as part of system simulation results. Further options are provided for direct steam injection, heated pan / steam HX and heated pan / hot water HX humdification. In these cases steam or hot water loads are reported and will be applied to steam or hot water plants in the plant portion of the program. These are new features which were not available in HAP v3.2.
  • System Design Reports
    • Air System Sizing Summary
      • In the Central Cooling Coil Sizing section, information about the coil CFM was expanded and relabeled to eliminate confusion. For example, in a VAV system the coil airflow at the time of peak load may be less than the airflow at other times. The program now provides three airflow items:
        - Coil CFM at Peak Load - This reports the coil airflow at the time of the peak cooling coil load.
        - Max Block CFM - This reports the maximum coincident airflow for the cooling coil. In certain situations this airflow differs from the coil airflow at the time of peak load, usually due to load diversity.
        - Max Possible CFM - This reports the sum of maximum zone airflow rates. It is useful in a VAV system if all VAV boxes will operate wide-open during a start-up period. It can also be compared with the "Max Block CFM" to judge load diversity.
      • In the Central Cooling Coil Sizing section a "sensible heat ratio" item was added.
      • In the Central Cooling Coil Sizing section a "maximum zone temperature deviation" item was added. This item accompanies the "zone t-stat check" item which shows whether all zones were within the thermostat throttling range at the time of peak load. The "maximum zone temperature deviation" shows how far the worst case zone was out of range, if any thermostats were out of range.
      • Cooling coil loads are now reported in both Tons and MBH (kW for Metric). When working in English units MBH is typically needed for equipment selection.
      • Heating coil loads are now reported in MBH (kW in Metric) instead of BTU/hr (W in Metric). Coil loads in MBH or kW are typically required when selecting heating equipment.
      • Sizing data for a "central reheat coil" used in active dehumidification systems has been combined with the "central heating coil" since one heating coil rather than two are typically used for both dehumidification reheat and space heating purposes.
    • Zone Sizing Summary
      • CFM/sqft (L/s/sqm in Metric) check figures have been added to the "Zone" and "Space" sizing tables in this report. In the "Zone" table, CFM/sqft is listed for each zone. In the "Space" table, CFM/sqft is listed for each space in each zone.
    • Air System Design Load Summary
      • Reporting of door information has been revised so that all door load components are included in a single line item. Previously, the solar load for door glass was reported as part of the "Solar Load" item, the glass transmission load for door glass was reported as part of the "Glass Transmission" item, and the conduction load through the opaque portion of a door was reported in the "Door Transmission Item". Now all three components are combined and reported as part of the "Door" item.
      • Data for a central reheat coil used in active dehumidification systems has been combined with the central heating coil load data.
    • Zone Design Load Summary
      • Reporting of door load information has been revised. See Air System Design Load Summary for details.
    • Space Design Load Summary
      • Reporting of door load information has been revised. See Air System Design Load Summary for details.
    • System Psychrometrics Report
      • The air density x specific heat x conversion factor has been added to the report. Both the sea level value (1.08 for English units and 1.207 for Metric units) and the value adjusted for site elevation are listed. This figure is useful when using temperature and airflow data on the report to hand-check sensible load calculations.
      • The air density x heat of vaporization x conversion factor has been added to the report. Both the sea level value (4747 for English units and 2948 for Metric units) and the value adjusted for site elevation are listed. This figure is useful when using humidity and airflow data to hand-check latent load calculations.
      • Data for a central reheat coil used in active dehumidification systems has been combined with the central heating coil load data.
  • System Design Calculations
    • Revised Convective/Radiative Split for Electric Equipment Loads
      • Due to recent research published in the 2001 ASHRAE Handbook of Fundamentals, the program now assumes 75% of electric equipment heat gain is convection and 25% is thermal radiation. Previously, the program assumed 30% convection and 70% radiation, based on recommendations from the ASHRAE Cooling and Heating Load Calculation Manual, 2nd Edition, (1992). This change was made to more accurately model heat transfer associated with electrical office equipment.
      • The higher the convection portion of a heat gain, the faster the heat gain will be converted into a cooling load. Therefore, this change will tend to cause HAP v4.1 system design calculations to yield higher estimates of cooling load. The size of this change in cooling load will depend on the size of electric equipment loads relative to the total system load.
    • Revised TF Coefficients for Windows with Internal Shades
      • The room transfer function coefficients used to calculate solar load for windows have been modified for the case where a window has internal shades. This change will allow solar load calculations to better reflect the fact that internal shades speed up the conversion of the solar heat gain to a cooling load (because the shade absorbs and then releases heat relatively quickly). This change was made to more accurately model heat flow for windows with internal shades.
      • This will change the shape of the solar load vs time of day profile versus results produced by HAP v4.0. It is difficult to predict how the change will affect the total peak zone or coil load. Whether these loads increase, decrease or stay the same depends on the behavior of other load components in the zone or system and the size of the solar load in relation to the total load.
    • Revised Modeling of Plenum Heat Gain for Terminal Systems
      • In a terminal system (DX fan coil, hydronic fan coil, WSHP) which uses a common ventilation unit and has a return air plenum, HAP now considers plenum heat gain to air returning to the terminal unit. The program assumes the terminal fan coil or heat pump is ceiling mounted for this system configuration. Therefore, it assumes that plenum heat gains affect air that returns from the room through the ceiling space to the terminal unit. This change was made to more accurately model heat flow in these systems.
      • In the previous version of HAP, plenum heat gains were only assigned to the air being exhausted from the system. The return air to the terminal unit was not affected.
      • This change is likely to increase peak cooling coil loads for terminal units versus results from previous versions of the program.

Plants
  • Plant Inputs
    • Revised Design-Only Plant Types
      • The roster of plant types has been revised to provide three options for plant design calculations: Generic Chilled Water, Generic Hot Water and Generic Steam. These plants only require specification of air systems served by the plant. They do not require specifics about chillers, cooling towers, boilers or pumps to be defined. As a result, these Generic plant types provide a quick way to generate peak load estimates for plants. However, the Generic types can only be used for plant design calculations. To use a Generic plant in an energy simulations, it must first be changed into a specific type of plant by first changing the plant type (system selections will be preserved) and then adding the specific data about plant configuration and control (see below).
    • Added Features for Modeling Plant Configuration and Control
      • The Plant form has been expanded to include inputs describing the configuration and control of components in the plant. This information is needed for energy simulations.
      • Chiller Plants - The user assembles the plant by linking chillers and cooling towers to the plant, specifying sequencing control and order, and describing free cooling equipment (if applicable). The user also configures the chilled water distribution system (see item #2 below).
      • Hot Water and Steam Boiler Plants - The user links a boiler to the plant. For the hot water case, the user also configures the hot water distribution system (see item #2).
      • Remote Source Chilled Water, Hot Water and Steam Plants - The user configures the hydronic distribution system for chilled water and hot water.
    • Added Features for Modeling Complex Hydronic Distribution Systems
      • The program provides options for modeling the following distribution systems:
      • Primary-Only Constant Speed (Non-Sequenced) - System contains one pump per chiller and chillers all unload equally (no sequencing). Three-way valves are used at the AHUs to control cooling delivered to the coils. Also available for hot water plants.
      • Primary-Only Constant Speed (Sequenced) - System contains one pump per chiller. Chiller and pump sequence on and off together. Two-way valves are used at the AHUs to control cooling delivered to the coils. This creates a variable flow system in which the constant speed primary pumps ride the pump curve.
      • Primary-Only Variable Speed - System contains a single primary pump, or a bank of pumps in parallel. Pumps are variable speed. 2-way valves are used at the AHUs to control cooling delivered to the coils. Flow in the secondary portion of the system responds to AHU loads. Flow in the primary portion of the system is held at or above the chiller and pump minimum flow levels. If primary flow exceeds secondary flow, the excess flows through a common pipe to bypass the secondary portion of the system. Also available for hot water systems.
      • Primary/Secondary with Variable Speed Secondary - A single variable-speed pump or a bank of variable speed pumps in parallel serve the secondary loop. Two-way valves are used at the AHUs to control cooling delivered to the coils. The primary loop contains one constant speed pump per chiller. The chiller and its pump sequence on and off together. A common pipe allows excess primary flow to bypass the secondary loop. Also available for hot water systems.
      • Secondary-Only Constant Speed - A single secondary pump or a bank of pumps circulates of water to AHU coils. Three-way valves are used at the AHUs to regulate the cooling or heating delivered to the coil. The pumps are constant speed and the system is constant flow. Only offered for remote chilled water and hot water systems.
      • Secondary-Only Variable Speed - A single secondary pump or a bank of pumps circulates water to AHU coils. Two-way valves are used at the AHUs to regulate the cooling or heating delivered to the coil. The pumps are variable speed and the system is variable flow. Only offered for remote chilled water and hot water systems.
  • Plant Simulations
    • Energy Simulation
      • HAP v4.1 adds the ability to run hour-by-hour simulations of plant operation to estimate energy use and energy cost. Simulations track plant loads and energy use by plant component such as compressors, cooling tower fans, boilers and water pumps.
    • Simulation Reports
      • Results from energy simulations are provided on a variety of reports. These reports provide plant performance data on an hourly, daily, monthly and annual basis in both tabular and graphical formats. In addition data on hours of operation and unmet loads are also reported. A feature is provided for exporting simulation results in a text format convenient for import into spreadsheets.

Buildings
  • General.
    • Buildings form a new category of data in HAP and are used in energy simulations. A ¿Building¿ is simply the container for all HVAC and non-HVAC systems which are included in an energy simulation. Building inputs allow the user to:
      • Specify the chilled water, hot water and steam plants included in the building.
      • Specify the air systems included in the building.
      • Specify rate schedules for each energy or fuel meter in the building.
      • Specify non-HVAC equipment which have not already been accounted for in other parts of the analysis.
    • One ¿Building¿ is defined for each design scenario in an energy analysis. Energy use and cost data for all the buildings in an energy analysis can be compared to determine which is the optimum design.
    • Note that Buildings are only used in HAP and not in HAP System Design Load.
Schedules
  • Expanded Assignments Table.
    • On the Assignments tab, the table has been expanded to include rows for all day types Monday thru Sunday plus Holidays. These additional rows are used to specify which profiles in the schedule are used on the different days of the week and at different times of year for energy simulations. For example, one profile could be used for weekdays in the summer months and another profile for weekdays in the winter months. This is a significant expansion of scheduling capabilities versus HAP v3.2.
    • Note that these scheduling capabilities are only used in HAP and not in HAP System Design Load.
Return to Top
Chillers
  • General.
    • Chillers form a new data category in HAP and are used in energy simulations. This data is only used in HAP and not in HAP System Design Load.
  • Methods of Inputting Chiller Data.
    • The program provides three different ways of entering chiller performance data, each suited to a common situation for acquiring performance data.
    • Importing a Chiller. If your sales engineer has provided you with an import file from one of Carrier's Electronic Catalog Chiller Selection programs, a full set of performance data for a specific chiller selection can be imported into HAP. No data entry is required. Users can also generate their own import file using the Carrier 30 Series Chiller Selection Program which covers Carrier 30-series air-cooled and water-cooled packaged screw, reciprocating and scroll chillers.
    • Chiller Template. If you have full load performance data plus limited part-load data such as IPLV or NPLV points, you can use the "Chiller Template" feature. Full load and part-load data is entered. The program then uses it to automatically generate a complete performance map for the chiller.
    • User Input. If you have full load performance data and a complete part-load performance map for the chiller obtained from catalogs or from the manufacturer, you can directly enter this data by hand.
  • Chiller Types.
    • HAP provides features for modeling a wide variety of chiller types including:
      • Water-Cooled Centrifugal
      • Water-Cooled Rotary Screw
      • Water-Cooled Packaged Screw
      • Water-Cooled Packaged Reciprocating
      • Water-Cooled Packaged Scroll
      • Water-Cooled Single-Effect Absorption (Steam)
      • Water-Cooled Double-Effect Absorption (Steam)
      • Water-Cooled Direct-Fired Absorption
      • Water-Cooled Engine Chiller
      • Air-Cooled Packaged Screw
      • Air-Cooled Packaged Reciprocating
      • Air-Cooled Packaged Scroll
  • Detailed Performance Data
    • Allows HAP to simulate changes in chiller performance as a function of load, entering condenser temperature and leaving chilled water temperature.
Return to Top
Cooling Towers
  • General.
    • Cooling Towers form a new data category in HAP and are used in energy simulations. This data is only used in HAP and not in HAP System Design Load.
  • Cooling Tower Modeling.
    • HAP uses a detailed thermodynamic calculation model to simulate the performance of cooling towers. This model requires simple input data obtained from equipment catalogs or the manufacturer. These inputs include design wet-bulb, range, approach, water flow and fan power.
  • River, Sea, Ground Water Option.
    • HAP provides an option for modeling use of river, sea or ground water as the heat sink or source for water-cooled equipment applications. With this option the user defines the average source water temperature for each month of the year.
Boilers
  • General.
    • Boilers form a new data category in HAP and are used in energy simulations. This data is only used in HAP and not in HAP System Design Load.
  • Boiler Options.
    • Features for modeling boilers include:
      • Modeling electric boilers.
      • Modeling fossil fuel boilers.
      • Analyzing performance via a detailed part-load performance curve, or via a simple average efficiency value.
Return to Top
Electric & Fuel Rates
  • General.
    • Electric Rates and Fuel Rates are two new categories of data in HAP. They are used in energy simulations to calculate the cost of electricity and fuel. Note that this data is only used in HAP and not in HAP System Design Load.
  • Basic Features.
    • Features similar to those in HAP v3.2 are provided in v4.1 to allow modeling of a wide variety of rate structures. These include features for modeling:
      • Simple rates with a single flat price for electricity or fuel.
      • Complex rates which include energy charges and demand charges.
      • Options for seasonal and/or time-of-day pricing.
      • Energy charges with flat price, energy (kWh) blocks, demand (kWh/kW) blocks, mixed blocks (kWh and kWh/kW) and 2-tiered blocked structures.
      • Demand charges with flat price or blocked structures.
      • Rachet, trailing window, minimum demand, power factor multiplier and demand multiplier clauses for determining demand.
  • Hourly or Daily Demand Option for Fuel Rates.
    • Fuel demand charges can be calculated based on the peak daily consumption or peak hourly fuel consumption.
  • Emissions Analysis.
    • Another new feature is the analysis of greenhouse gas and pollutant emissions. This is sometimes required for Green Building studies. For the electric utility and each fuel source average emission rates of carbon dioxide (CO2), sulfur dioxide (SO2) and nitrous oxides (NOx) can be defined. Later the program will estimate the total emission of these gases due to the consumption of energy and fuel for each building scenario.

Reports
  • Report Viewer Upgrade.
    • The Report Viewer software, used to display reports on the computer screen, has been revised. It uses a different operating scheme than the previous viewer.
  • New Report Format.
    • All reports are now generated in Rich Text Format (RTF). Therefore, data can be copied from the report into other documents. In addition, reports can be saved to disk as an RTF format file. These files can be easily loaded into word processor and spreadsheet software programs.
  • System Design Reports.
    • Minor changes and additions have been made to system design reports.
  • Simulation Reports.
    • Reports for system simulations, plant simulations and building simulations in an energy analysis have been added.
