# Optical tuner for sustainable buildings

## TL;DR

A new fluid-based system for buildings can significantly reduce energy use for heating, cooling, and lighting.

## Contribution

A fluid-based building interface that selectively tunes light absorption and dispersion to reduce energy consumption.

## Key findings

- The system could reduce annual energy consumption by up to 43% compared to existing technologies.
- The system selectively tunes light absorption and dispersion to optimize energy use.

## Abstract

A recent publication in Proceedings of the National Academy of Sciences describes a fluid-based building interface to reduce energy use for heating, cooling and lighting by selectively tuning light absorption and dispersion. Models showed that this system could reduce the annual energy consumption by up to 43% compared to existing technologies.
