I Put a Bookshelf in My Entryway to Stop the Draft (And My Heating Bill Dropped)
A Reddit user shares how blocking a drafty entryway with a bookshelf unexpectedly lowered heating costs and made the apartment feel cozier.

The Problem
Our apartment has this weird entryway that funnels cold air straight into the living room. Every winter, the thermostat said 68 but it felt like 58. I tried weatherstripping, draft stoppers, even hung a blanket over the door. Nothing worked. The heat just... left.
What They Tried
I moved a tall IKEA Billy bookcase into the entryway, right against the wall that faces the front door. It was mostly to store shoes and mail, but it accidentally created a barrier. The cold air now hits the shelf and kind of swirls back instead of shooting down the hall. I also added a small rug in front of the door.
What Happened
The living room stays warmer. Not dramatically, but enough that I stopped wearing a hoodie indoors. The heating bill for January was $42 less than last year. The entryway feels less like a wind tunnel and more like a actual room.

1. The Original Principle
Original Chinese
水口则爱其紧心葫芦喉。抱身则贵其弯如牛角样。注解:出水口则爱其紧心葫芦喉。水抱穴身则贵其弯如牛角样。
English Translation
The classic text advises that the 'water mouth'—the exit point of a site—should be tightly closed like the neck of a gourd, and that surrounding water should curve gently like a cow's horn to embrace the dwelling.
2. About the Source
雪心赋 论水法 by Bu Yingtian · China · Tang Dynasty (618–907 CE)
The Snow Heart Rhapsody is a poetic yet rigorously analytical classical text on landscape assessment. Written in rhymed prose, it covers mountain forms, water patterns, terrain energy, and site selection with remarkable literary elegance. Its observations about how land contours create sheltered, comfortable settings for human habitation remain relevant to modern site planning and environmental psychology.
3. How This Principle Applies to This Case
The classical principle describes how an exit point should be constricted to prevent the loss of beneficial resources, while surrounding flows should curve gently to embrace the space. In this case, the entryway acted as an unsealed 'water mouth,' allowing warmth (and money) to escape. By placing a tall bookshelf as a partial barrier, the resident created a constriction that slowed air movement and redirected it. Modern building science confirms that reducing cross-ventilation and creating air pockets can improve thermal comfort and lower energy costs. The curved path around the shelf mimics the 'embracing' effect, making the space feel contained rather than exposed.

Sourced from altitudes above 4,000 meters in the Himalayan range — the highest place on Earth and the closest to the sun. These crystals formed over millions of years in some of the planet's most pristine conditions, untouched by industrial pollution. Each piece carries the raw, unfiltered energy of the mountains. Whether placed on a nightstand, a desk, or a meditation corner, they serve as a quiet anchor — a daily reminder to pause, breathe, and reconnect.
