Utilizing Passive Solar Energy

Using passive solar energy can save money on heating and cooling bills.

By utilizing passive solar energy, our ancestors could use temperate differences to heat and cool their homes. The sun rises in the east and sets in the west, right? And it is higher in the summer than in the winter. We know that. Thousands of years ago they knew that. By using the difference in the temperature between day and night, summer and winter, they could trap the sun’s energy to make their homes pleasant to live in—warm in the winter and cool in the summer. In the temperate parts of the States, houses were built to have southern exposure. In the hot parts in the South, they had deep porches and large overhangs to provide shade during the hottest parts of the day. What they did was to live in harmony with the cycle of nature – they used the sun’s passive energy, with no technological devices whatsoever.

Solar energy is rapidly gaining popularity among Americans, for various reasons. Of about 116 million homes in America, 200,000 are using some kind of a photovoltaic solar (PV) system, with about 10,000 using solar energy alone as their source of power. The prices are going down, the technology is becoming more available and affordable, and it is very attractive to people wishing to go off grid. But, PV solar systems mean high-level technology, require a great deal of knowledge for maintenance, and the initial cost is still relatively high.

Passive solar energy uses the knowledge of the local climate, the angle of the sun’s passage across the sky and the nature of materials used to build the home. By making the house the right shape, placing the windows right and positioning walls, windows and roofs in the right direction, one can cut the building’s energy costs by 30 to 40 percent with no additional cost.

The science behind passive solar energy

There are a few scientific facts that enable us to use the sun’s passive energy:

  • Heat naturally travels from a warmer to cooler area until the temperature equalizes.
  • Certain materials retain energy (heat) better than others. This is called thermal mass. Water, earth, rocks and bricks have the highest capacity to retain heat.

How to design a house to use passive solar energy

Although it is easiest to use passive solar energy if you are designing your house from scratch, you can make changes to your existing house in order to decrease your heating or cooling bills. In fact, most of the principles of designing a passive solar house make sense in building any house, as one uses the power of the sun to make living more pleasant and less expensive.

Although designing a house in order to minimize or completely eliminate use of fossil fuels for heating or cooling requires a lot of knowledge and planning, the basic principles behind a passive solar design are simple:


If terrain allows, the longer axis of the house should be oriented east/west, so that most rooms face sunny south. Large tilted windows trap a maximum amount of the sun’s energy, which naturally gets transferred to the interior. In the summer, when the sun’s arc is much higher, these same rays will bounce off vertical panes of glass.

Prevailing winds should be allowed to pass through to help air circulation and equalization of the temperature. High ceilings allow hot air to travel upwards and naturally cool the space.

Planting evergreen trees on the north side of the house will protect the house from harsh winter winds, and leafy deciduous trees planted to the south will provide pleasant cooling shade in the summer. Once they shed their leaves in the winter, they allow the sun’s warmth to pass through.


If you allow full sunlight to come through your large southern facing windows in the summer, you would be living in a boiler. Deep overhangs keep the summer high-passing sun from overheating your living space, but in the winter, when the sun is much lower, the overhang is not in the way. The same seasonal shading can be achieved with trellises covered by seasonal vines, which die down in the winter, or deciduous trees which shed their leaves in the winter. Shutters and curtains that keep the sun from overheating the living space in the summer can keep the temperature in the room almost 20 degrees lower.

Windows and patio doors

Windows are your solar collectors, so they should be located mostly on the southern side of the house. Limit the number and size of windows on other sides of the house. They should play an important role in air circulation. Keep in mind that your windows not only collect energy, but lose it too, so do not exaggerate in size. Thick drapes or shutters should keep the rooms from losing heat during the night. Double panes play the same role.


A house in which every surface opened to the environment is well-insulated keeps the same pleasant temperature year round. Insulating materials, which do not conduct heat well, prevent heat loss in the winter or heat entrance in the summer. Keeping temperatures even is the key so that you do not have to waste energy by raising or lowering temperatures to be comfortable.

Thermal mass

Thermal mass is a building material that collects and distributes solar energy. It is a solid or liquid material that absorbs and stores heat or coldness and releases it when it is needed. While other building principles are just common sense ways of building a house in order to save on heating and cooling costs, use of thermal mass really makes passive solar design unique.

Characteristics of some materials that store and distribute the sun’s energy well were known to our ancestors a long time ago. People were building houses in Mexico of adobe, or were covering roofs with sod in England, or were baking bricks all over the world, or were building castles with large stone cubes.

During the day and in the summer, the sun heats walls, roofs and floors made of a thermal mass, such as concrete, earth, brick or water. At night, or in the winter, when the temperature of the surrounding air drops, they release that stored heat because the inherent nature of the materials try to equalize the temperature with its surrounding.

In addition, solar panels can serve not only as photovoltaic collectors of the sun’s energy, but work in a passive way as thermal mass.

NYC Adds Nearly 4,000 People Who Never Tested Positive To Coronavirus Death Tolls

New York City added nearly 4,000 people who never tested positive for the coronavirus to its death toll Tuesday, bringing coronavirus-related deaths in the city to around 10,000 people.

The city decided to add 3,700 people to its death tolls, who they “presumed” to have died from the virus, according to a report from The New York Times. The additions increased the death toll in the U.S. by 17%, according to the Times report, and included people who were suffering from symptoms of the virus, such as intense coughing and a fever.

The report stated that Democratic New York City Mayor Bill de Blasio decided over the weekend to change the way the city is counting deaths.

“In the heat of battle, our primary focus has been on saving lives,” de Blasio press secretary Freddi Goldstein told the Times.“As soon as the issue was raised, the mayor immediately moved to release the data.”
