Enviro Energy International, Inc. is a Canadian company that specializes in water and energy conservation. They have patented their Fireplace Plug in Canada and the U.S.

Fireplace Plug: The Draft Stopper

The Fireplace Plug is an inflatable polyurethane “pillow” that seals the fireplace when it’s not in use. This prevents drafts from coming into the building, which can reduce heating and cooling costs by up to 30%.

The Fireplace Plug fits below the damper, which Enviro Energy claims is often missing or warped. In fact, it will stop drafts even when the damper is shut.

The plug is easily installed. It comes with a tube and prop device, which are used for inflating the “pillow”, then pushing it into place. It’s very durable and meant to withstand many temperatures and deposits.

Where to Buy the Fireplace Plug

There are two types of Fireplace Plugs available for varying types of fireplaces (or fireboxes):

• Masonry firebox with rectangular dampers, up to 38″ wide
• Metal, zero clearance firebox or gas firebox with circular damper, up to 18″ wide

The Fireplace Plug retails for $54.95 and is available for purchase on Enviro Energy’s website.

LEED Credit Overview

According to LEED for New Construction 2009, the Fireplace Plug could contribute to the following credits:

Energy and Atmosphere (EA) Prerequisite 2 Minimum Energy Performance (0 points)Fireplace Plug

This credit establishes a minimum level of energy efficiency for buildings, based on energy costs. The Fireplace Plug could help to improve the building’s energy efficiency and reduce heating and cooling costs, contributing to this credit.

EA Credit 1: Optimize Energy Performance (1-19 points)

This credit rewards LEED projects for achieving energy efficiency beyond the minimum set forth in EA Prerequisite 2. Points are awarded based on the energy cost savings percentage – the higher the percentage, the greater the number of points awarded. The Fireplace Plug reduces energy costs, meaning they could potentially contribute to this credit.

A recent graduate of Cornell University, where she studied Environmental Science and concentrated in Sustainable Development. Her interest in green building and LEED stems from her project-based coursework at Cornell, where she proposed design strategies for sustainable developments in Helena, MT and Ithaca, NY. Claire also exercised her passion for sustainability and energy conservation through extracurricular activities at Cornell, such as Solar Decathlon, Lights Off Cornell and Sustainability Hub. For the last three summers, she worked on energy projects at a town government, including an on-site hydrogen station and EECBG-funded activities.
