About the creator
My name is Rudra Sutariya, and I built Watt & Wall to make everyday home energy and renovation planning easier to understand. The website is developed with Next.js and React, with a strong focus on clear content, accessible interactions, responsive design, and SEO best practices so useful information can reach the people who need it.
What we are building
Watt & Wall brings small, useful calculations and their explanations into one calm place. The goal is not to produce the biggest possible answer or hide a formula behind a result. The goal is to help a homeowner check inputs, understand units, compare scenarios, and know when a professional or product document should take over.
How the site is maintained
The Watt & Wall project team maintains the calculator code, explanatory pages, source notes, and review dates. The team uses typed calculation modules and regression tests for formulas, then checks the rendered pages for keyboard access, responsive layout, and consistent light-theme rendering.
- Calculator pages explain their scope before asking for values.
- Sources and assumptions are shown near the result, not hidden in a separate technical document.
- Claims are kept narrower than the evidence; no savings, accuracy, approval, popularity, or professional-endorsement claim is implied.
- When a page changes materially, its review date and supporting research should change with it.
What we do not do
Watt & Wall does not inspect a property, set a utility tariff, select a product, certify an installation, or provide a contractor quote. Calculator values are planning aids. Read the full estimate disclaimer before relying on a result for a purchase or project.
