**[ENERWIN e9 has been replaced by Version 10]**

=====================================================

NOTE: This software is supported on

Microsoft Windows 10® and Office® 3016 and 365.

Microsoft Excel® is an integral

feature that shows tabular results,

allowing for creation of bar charts

and graphs of energy consumption.

                                                                             Pro Edition! (Version upgrade  10.6e+)  

 

Some new things in Enerwin-10 Pro:       

 

  1. Weather data base upgraded to 4700+ cities and covering 8 different regions for easier look-up.  This will be updated again in 2020 when the WMO (World Meteorological Organization) publishes it new 30-year climate norms data.

  2. Updated the energy efficiency criteria to meet the latest Standard 90.1-2016 and Standard 189.1-2014 for Green Building Designs.  These will be updated again in the year 2020.

  3. Improvement in the appearance of the 3D imaging in the sketch package as well as some of the appearance of selection options in the main menu screen.

  4. More attractive pricing structure to make available a nominal cost for universities and other organizations to purchase multi-user site licenses with no expiration date, a lower cost single user professional license.  Students request this:  one semester, free 5-month license for individual university-registered students (not renewable.)

 

PLEASE:  Report back to enerwin@suddenlink.net if you run into problems.  This is the best way to make the fixes possible.

General Note:

     Versions EC and 10 include greenhouse gas emissions calculations and

        compatibility with ASHRAE's International Weather Data Base (IWEC). 

 

ENER-WIN© is a Windows-based hourly energy simulation model for evaluating whole-building energy performance.  The program features an interactive graphical interface for input and output.  The simulation model uses streamlined algorithms that permit hour-by-hour energy calculations in minimal time.  The program's tabular results include monthly and annual utility energy and costs, peak HVAC loads, a thermal comfort analysis and a life-cycle cost summary.  It has a Visual Basic interface and a FORTRAN-95 simulation engine that features transient modeling based on sol-air temperature, time lag, and decrement factor; zone loads and temperatures based on a thermal balance methodology; and daylighting algorithms based on a modified Daylight Factor methodology.  The software contains default data bases populated with weather data for over 4700 cities worldwide, lighting power densities based on 40 building types in ASHRAE's energy-efficiency Standard 90.1. The latest version, Enerwin-e9 lets the user select from three different standards (90.1-2010, 90.1-2016, or the Standard 189.1-2014 for Green Buildings.)  Enerwin-EC is similar but is based mostly on U-Factor requirements from Standard 90.1-2007.  Version 10 Pro adds significant precision in selecting the default wall and roof U-factors and window solar heat gain coefficients (SHGC), in that these are now sensitive to not only the building type selected, but also the particular code selected and the climate zone represented by the selected city.  Ventilation rates, as well as occupancy densities, are based on the ASHRAE Standard 62.1 for acceptable indoor air quality.  Occupancy and other 24-hour profiles, such as lighting and hot water usage, are based on sources that have been involved in energy simulations for buildings, particularly the U.S. DOE and the COMNET (Commercial Buildings Energy Modeling Network) organization.   Enerwin-10  has three separate schedules ("Mon-Fri", "Sat", and "Sun") for each building type and for each of the usage parameters (occupancy, hot water use, lighting, receptacles "plug loads", fans and ventilation, summer thermostat settings, and winter thermostat settings.)   Versions EC and 10 include the calculation of greenhouse gas emissions caused by the building's energy consuming systems.   If gas or oil are used for on-site heating, the emissions are calculated directly from the fuel consumption.  Emissions for all electricity use are calculated at the power plant, showing values for gas-fired, oil-fired, and coal-fired generators.  Emissions are calculated in terms of tons (short or metric) of Carbon Dioxide (CO2), Sulphur Dioxide (SO2), and Nitrous Oxides (NOx).

         (Do not attempt to add these cities to the Enerwin-10 weather database.  The new weather database has

            been divided into 8 different directories, representing 8 different regions on earth.  The older Enerwin-e9

            weather database is in a single file and can be updated with the weth.zip data.  However, there is usually

            no need to update the weather database for Enerwin-10, because the 4700-city files are already in the

            correct formats in their respective regions.)
