Threshold Calculator
Updated 12/13/09 - This spreadsheet calculates the customized household energy allowance that must be met or exceeded to meet the Thousand Home Challenge (THC), using OPTION A (based on actual pre consumption) or Option B (based on climate, finished floor area, number of occupants, and heating source) User inputs are entered in the first tab, User Interface. The Thousand Home Challenge is in the pilot phase. Comments on the Threshold Calculator should be sent to Linda Wigington, lwigington@afordablecomfort.org. Check back for further refinements and more information about the Threshold Calculator.

Planning Tools for Potential THC Projects
-
1. THC Homeowner Priorities Worksheet
THC Homeowner Priorities Worksheet helps a household clarify their priorities in order to make the value proposition for a proposed deep energy retrofit project. This supports the design process and improves communication with the project team (or family members) as well.

2. THC Heal-Saf-Durability Have-a-Plan
THC Heal-Saf-Durability Have-a-Plan raises issues that may be relevant to a retrofit project’s success and begins to document health, safety, and durability considerations within the scope of work.
thc_heal_saf_durability_have_a_plan.xls -
3. THC Paths to Thermal Comfort
THC Paths to Thermal Comfort stimulates out of the box thinking to support the examination of solutions to reduce heat loss or heat gain and to enhance thermal comfort.
thc_paths_thermal_comfort.pdf -
4. THC Reduction Matrix
The THC Reduction Matrix can be used for any proposed or potential Thousand Home Challenge project. It allocates pre energy use and estimates what and how reductions will occur to meet the Thousand Home Challenge.
thc_reduction_matrix.xls -
5. THC Ten Steps to Deep Energy Reductions
Ten Steps to Deep Energy Reductions provides a framework for assessing and implementing a deep energy reduction project for a specific dwelling.
thc_ten_steps_to_deep_energy_reductions.pdf -
6. THC Principles for Smart Staging
If doing an "All-at-Once" project is not an option, consider these principles as you plan a staged approach to deep reductions.
