Buildings and Blower Doors

Dwellings today are erected with more complexity. Today, houses need to undergo several tests and calibration in order to determine the homeowner’s comfort and the ease and ability of the household to conserve energy. Homes and edifices are frequently checked if it meets the requirements set by the board.

In the years past, only a small team of people is needed to build a home. Today, it involves energy auditors or building analysts with BPI (Building Performance Institute) certification. A building analyst checks if the house meets the standard set by the Building Performance Institute.

The Environmental Protection Agency (EPA) can give tips on improvement of energy efficiency in one's home. A sample program is called the ‘Energy Star Program’, which helps homeowners in testing and ensuring that their houses are energy efficient, durable, comfortable, and with quality air inside, while checking indoor moisture. It is now enforced in several departments.

The state energy office involved initiates and implements home energy audits. After conducting tests, the ‘Energy Star Program’ makes several recommendations such as sealing air holes or gaps, sealing ducts, improving lighting, upgrading heating and cooling systems, adding heat recovery ventilation or controlling moisture. There are many devices that an energy auditor might use in his evaluation and one of them is a blower door.

Blower door has several functions in the analysis of a building. It can detect a structure's imperviousness from external factors, its energy saving capacity, and efficiency of fire extinguishers. Here is the step by step system.

Air is brought inside the building through the blower door that was temporarily fixed to onto the main entrance. If too much pressure is present, the air tries to squeeze out of the structure through unnoticeable gaps present in the building. Structures with a lot of leakage areas need a lot more time to build up pressure inside.

Slackened areas in the structure ought to be filled, in order for the program to be considered a success, Varying degrees of air compression will have to be made to confirm a leak in the building. It will then use summations to pinpoint places of seepage.

Conservation Strategies is a top producer of blower door in the market. One of their well known products is the Minneapolis Blower Door. It's very efficient and is the blower door of choice by many.
