About RHEAT™

RHEAT(™) has been developed by Build Change to help countries, states, territories, and cities to identify key gaps and challenges as they work toward achieving resilient housing at scale.

RHEAT™ can be used by governments and implementers as they prepare to launch a housing program, or during the implementation of an existing program. The tool supports users to obtain a snapshot of the current housing environment, by assessing conditions at a given point in time. It can be a useful monitoring tool to guide understanding on priorities and resource allocation, and in doing so can help to maximize the chance of a program’s success.

RHEAT™ specifically tracks progress against the three areas of People/Policy, Money, and Technology. Users are guided by a series of benchmark indicators and a score is assigned to each based on the current level of progress in that area. The tool should be revisited at regular intervals to review and reassess progress against each indicator. Over time, progress is observed as the colors on the assessment tool change from red—indicating that certain criteria are inexistent or not working—to blue—indicating that resilient housing goals have been achieved.

Theory of Change

RHEAT™ assesses three areas: People/Policy, Money and Technology, which Build Change has identified as the three main barriers to adoption of resilient housing at scale. Put simply, homeowners will not live in disaster-resistant houses unless they can afford to, and have access to needed technology, materials, and skilled construction workers. They also need government agencies to be able to provide incentives and enforce building standards. The high level of interdependence between the three main areas makes it necessary to take a holistic approach that considers all three, to successfully design policies, programs, or products to overcome gaps and challenges in any one area. For more information on Build Change’s Theory of Change and implementing successful resilient housing programs, refer to The Build Change Guide to Resilient Housing: An Essential Handbook for Government and Practitioners.

This tool is intended to provide a quick, high-level snapshot of the ecosystem for resilient housing for a user-specified location and point in time.
Getting started:
  • Start by entering the basic information at the top of the form. This will be displayed on the front cover of the final pdf version.
  • The tool can be used on a browser screen, or it can be enlarged to full-screen by clicking on the green button with four arrows in the top left corner of the form.
The indicators:
  • The three broad categories of barriers to resilient housing—people/policy, money, and technology—are defined by a series of indicators (e.g. P1: National Policy and Legal Framework for Risk and Resilience) and sub-indicators (e.g. 1) Decent housing is a constitutional right).
  • Use the "+" and "-" buttons on the left to toggle open/closed the indicators and sub-indicators for each of the three main categories.
  • Score each sub-indicator from 1 to 4 by using the drop-down menus. Take a look at the scoring key provided below for the definition of each score.
  • To help gauge the scoring, there is a statement in italics next to each sub-indicator that describes a score of 4 “At destination (All good)”.
  • Based on the scores entered for sub-indicators, average scores are automatically calculated and displayed for the indicators and categories.
  • It’s highly recommended to use literature reviews and stakeholder engagement to inform your scores. The scope will vary with project size and resources, but should aim to encompass sufficiently diverse sources to minimize subjectivity.
  • It’s also highly recommended to score every sub-indicator, but if there are one or two that are not relevant or unknown they can be left blank. Sub-indicators that are left blank are not considered in the average scores for indicators and categories, and are highlighted as incomplete in the final pdf version.
  • The comment box is where you can provide any background information or justification for the chosen score. These comments will appear in the final pdf version.
  • Key Labels:
1 Initial Stages (Inexistent or not working)
2 Getting ready (Existent, needs fixing)
3 On the road (Working, needs improvement)
4 At destination (All good)
Saving, submitting, editing and printing RHEAT™ assessments:
  • The scores and comments will automatically save to your browser’s cookies, so there is no need to manually save the form or complete it in one session. You can pick up where you left off at any time by simply re-opening the page.
  • Once you have finished entering all scores and comments, click “Submit” at the bottom of the form. This will generate a pdf report of the RHEAT assessment that can be printed or downloaded.
  • After submitting, you can still edit the RHEAT™ assessment at any time by clicking the pencil and paper icon that is adjacent to the assessment title tile. This will reopen the editable RHEAT™ assessment form, maintaining all scores and comments that were previously entered.
Creating and Comparing Multiple Assessments:

Creating multiple RHEATs is a helpful way to compare the current status of different regions, or the progress of a region over time.

  • Once you have submitted one RHEAT™, additional assessments can be created by clicking the gray “Start Assessment” button. If you want to create a comparative report, it’s important to give each new assessment a unique title, and to keep the date, evaluator name, and evaluator organization the same.
  • Every time a new assessment is submitted, a tile with the assessment title is created at the top of the page. The active RHEAT™ is highlighted in blue (non-active forms will have gray tiles).
  • You can always go back and edit any RHEAT™ assessment by clicking the paper and pencil icon next to the tile with the RHEAT™ title. All assessments will be automatically saved in your browser for one year.
  • To generate a comparative report that shows the scores of multiple assessments together:
    • First choose which assessments to include: all assessment title tiles with an “x” next to them will be included. Clicking the “x” changes it to a “+” and removes it from the comparative report.
    • Next click the gray “Show Comparative Report” button in the top right corner. This will generate a pdf report with the scores from all selected assessments shown in side-by-side columns.
Resetting the form(s):
  • “Reset Form” will delete all scores and comments in the active RHEAT™ form, saving only the title, evaluator name and organization, and date.
  • “Reset All” will delete all scores and comments from all RHEAT™ forms.
