How to Keep Your Tiny House Cool
Heat can quickly build up in any space, particularly a smaller one and summer can be intense. After a few days of 100 degrees plus heat you might start thinking about how to efficiently cool down your tiny house.
Smaller spaces don’t often include central air conditioners and actually waste money in over-cooling a small space. The best option to cool a small space is to invest in a portable air conditioner.
Portable ac’s provide specific spot cooling at pennies to a dollar compared to traditional systems. A portable air conditioner that has casters on the bottom for ease of moving is your best bet to cool down your tiny house.
Tiny houses are efficient to heat and cool so don’t worry about the added $5–10/month additional cost in maintaining a comfortable temperature.
The best feature of a portable air conditioner is that it is extremely easy to install. You will receive a window kit through which you will place a small exhaust so the heat removed from the air in your tiny house can be evacuated. You can also install a portable air conditioner to vent through a ceiling using a ceiling vent kit.
Portable air conditioners do not hang out of your window so you don’t have an eye-sores defacing the beauty of your tiny home. And while a window unit may do an excellent job in cooling the house, it has 2 main drawbacks: the weight of the unit and the noise. In a building where every ounce is important, a window unit doesn’t make much sense.

The Avenger 10,000 BTU Portable Air Conditioner with Remote Control and Dehumidifier function provides ample airflow to cool spaces up to 300 sq. ft. and the two-way up/down air deflection circulates air evenly throughout the room.
The digital controls offer precise temperature adjustments, and the remote control lets you control the air conditioner from across the room.
The 3-speed fan and 24-hour timer allow personalized settings to fit your needs. The window installation kit and hose are included to make installation easy. Even with portable cooling units, there are additional optimizations you can utilize to reduce in-home heat.
Passive Cooling and Active Cooling
There are two types of cooling: passive and active. Active cooling is direct cooling, like a portable AC, central AC, or evaporative coolers. Passive cooling includes indirect ways of cooling your tiny home.
Tiny House Site
Trees and breeze are perfect for blocking the sun and convective cooling, so incorporate them into your tiny space planning. If possible, park on grass surfaces during the summer as black asphalt surfaces can dramatically increase the heat.
Window Shadings and Sun Screen Fabric Awnings
As much as half the heat in your house can come from unshaded windows. The heat gain from a hundred square feet of eastern or western facing windows is equivalent of running your heater for several hours.
Setting up a canopy outside your house and above the window blocks the intense heat from penetrating your tiny home. Window awnings offer additional protection against heat. Unlike window shades, awnings are retractable, which allows for additional exterior options.
Trellis, Living Wall System & Vertical Gardens
Let nature block out unwanted sun and heat. Plants are a great natural way to provide shading and cooling. The greenery increases oxygen levels and adds additional shading and cooling from the sun’s heat.

Cool Metal Roofing
Reflective metal roofing has been used for centuries and keeps your tiny house cooler as well as saving on cooling bills. These types of roofs offer enhanced energy efficiency through solar reflectance. Cool metal roofs are also EPA Energy Star approved.
