Version 8.3.3.11 (Issued May 19, 2008)

NEAT
• Costs for the Fill Ceiling Cavity measure, as printed on the Recommended Measures report, are now correctly listed under the Measures tab as well.
• The block of Added Insulation information on the Finished Attics tab is no longer removed from the form when “None” is chosen as the Added Insulation Type.
• A zero can no longer be entered for the Foundation Wall Height on the Foundations tab, which previously caused the program to crash.

Version 8.3.3.8 (Issued March 19, 2008)

General
• Corrects an intermittent problem that was introduced in Version 8.3.3.6 in the Setup Library with the Library Measures form not being displayed properly.
• Corrects a problem that was introduced in Version 8.3.3.6 in Data Link with the Import/Export via Database Files data transfer method.

MHEA
• The Addition Floor Type field is now filled in when an existing audit is copied.

Version 8.3.3.6 (Issued December 19, 2007)

General
• The Weatherization Assistant and NEAT can operate under Vista (and MHEA with conditions).
• The Weatherization Assistant opens with a window sized for 1024x768 resolution.
• Data sheet views are no longer persistent.
• There are an additional number of reports available in the data sheet view to facilitate exporting results to spreadsheets.

NEAT
• The wall stud depth is specified by the user.
• The installation of wall cavity insulation is evaluated even if the wall is already partially insulated with a batt, blanket, or rigid board insulation.
• R-49 is evaluated as a 5th insulation option for attics.
• R-38 is evaluated as a 4th insulation option for floors.
• The data input form for foundations is reformatted to clarify and simplify inputs.
• The floor joist size is specified by the user in evaluating sill insulation.
• The user can define up to six insulation types each for the attic, knee wall, exterior wall, floor, sill, and foundation wall.
• Fuel switching for fossil-fueled heating systems is allowed.
• Replacing an electric heating system with either electric resistance heaters or a heat pump is evaluated.
• The installation of a heat pump is evaluated when only existing window air conditioners exist or when no air conditioning system is presently installed.
• Kerosene heating systems are treated the same as oil heating systems.
• Space heaters can be replaced to eliminate secondary heating systems.
• The algorithm associated with replacing space heaters is fixed.

MHEA
• Window retrofit recommendations are based on individual window descriptions.
• Sealing (weatherizing) windows is evaluated as a 4th window retrofit option.
• The selection of window retrofit options is consistent with NEAT’s approach.
• The space-heating system efficiency improvement from a tune-up is consistent with NEAT’s (i.e., the efficiency improvement becomes less as the existing efficiency increases).
• Separate installation costs are entered for measures applied to the mobile home itself and to the additions on mobile homes.

NEAT and MHEA
• Assigning an auditor to an audit is no longer required.
• Drop-down fields having only one available selection are automatically filled in.
• The “Client ID” field is left blank when a new audit is created to reduce data entry errors.
• “Additional Cost” fields are available for each window retrofit option.
• The estimated energy consumption of the refrigerator can be viewed without having to evaluate a replacement unit.

Version 8.2.7.8 (Issued September 9, 2006)

General
• A report is provided which lists all the measure costs entered in the Setup Library.
• Different sections of the Input Report can be selected for printing.
• Corrects problems associated with the client name missing from the Recommended Measure Report, changing the user-supplied logo used in output reports, the status history as seen on the Client Completion Report, designating user-defined measures as being applicable to NEAT and/or MHEA, and activating the password feature before any users with passwords have been entered, and

NEAT
• The Rs/inch for user-defined wall and attic insulation types are displayed in the associated combo boxes.
• The algorithm relating the year an air conditioner was purchased to a default efficiency is updated.
• Corrects problems associated with the loss of envelope measure recommendations when a space heater replacement is recommended, not evaluating user-defined wall insulation types for frame walls with existing insulation, incorrect window retrofit costs displayed on the Measures tab, the annual pre-weatherization energy consumption displayed on the Recommended Measure Report being too low when duct sealing is evaluated (representing consumption after duct sealing but before the installation of other recommended measures), and an incorrect annual post-weatherization energy consumption displayed on the Recommended Measure Report when a space heater replacement is recommended.

MHEA
• The algorithm relating the sum of the pressure pan readings to the duct leakage rate is modified.
• Window and door codes are listed on the Recommended Measures Report.
• The order that recommended measures are listed on the Recommended Measures Report are modified to be consistent with NEAT.
• Corrects problems associated with a door replacement not being evaluated unless a mandatory replacement is specified, and the post-weatherization annual consumption reported in the Recommended Measures Report when baseload measures are recommended.

Version 8.2.7.6 (Issued August 26, 2005)

General
• The Weatherization Assistant’s optional administration features are introduced, including agency-related contact information, client data intake, recording of health and safety issues, recording of diagnostic measurements, work orders, status tracking, simplified cost accounting, inventory control, report generation, site mapping, and digital photo storage.
• Client information is entered separately from NEAT or MHEA.
• NEAT and MHEA share a common Setup Library.
• A Supply Library is introduced.
• Up to 65,000 characters can be entered in each comment field.
• Comments can be directly imported into work orders.

NEAT
• The user can enter a specific R-value of additional insulation to evaluate for the attic.
• A multiple number of finished attic components can be described.
• An “Additional Cost” field is available separately for foundation floor insulation and foundation wall insulation.
• A multiple number of space-heating systems can be described.
• Standard and high-efficiency replacement space-heating equipment can be described separately.
• Secondary space-heating systems can be replaced along with the primary space-heating system by a replacement unit.

MHEA
• The leakiness of individual windows is specified and used in estimating the energy savings from window retrofits (equivalent to NEAT).
• A distinction is made between existing floor insulation that is installed between the joists and under the joists.
• The data input form for the floors of additions is reformatted to allow a more accurate description.
• The length of the thermostat setback is based on the setback during the night rather than the day.

NEAT and MHEA
• Energy-efficiency and repair measures can be predefined and selected under the Itemized Cost tab.
• The data input form for refrigerators is reformatted to add data fields for the style and defrost mechanism for the existing and replacement units and to show the estimated energy consumption of the existing and replacement units.
• The algorithm for estimating the energy consumption of the existing refrigerator includes the location of the unit and the condition of the door seals.
• The database of refrigerators is expanded.
• The heat content of fuels and the uniform present worth factors are included in the Setup Library.
