[Building heat recovery](https://www.materialinsights.org/energy/e_building_recovery/) (energy) and [Energy in buildings](https://www.materialinsights.org/energy/e_buildings/) (energy): 3 relationships.

## How they are linked

### 1. Energy flow

*Physical flow · Direct · Energy in buildings → Building heat recovery*

Ventilation and drain heat recovery reuse household heat.

### 2. Energy flow

*Physical flow · 100% of flow · Building heat recovery → Energy in buildings*

Recovered heat cuts building heating demand.

- **100%** of Building heat recovery's energy goes this way

### 3. Price link: energy saved

*Cost and price · Strong · Both ways*

Recovery units cut heating, cooling and hot water bills, so household power and gas prices set their value. Yearly moves correlate at 0.70 with the electricity proxy, mostly a shared US inflation trend.

- **0.14** monthly change correlation
- **0.70** 12-month change correlation
- **1.61** fitted elasticity
