What Are Zero Energy Prefab Homes?


What Are Zero Energy Prefab Homes?

The main feature of prefab homes is efficiency. They involve less material waste and quick manufacturing time. With time, environmentally friendly designs have become a prominent feature of prefab homes. Zero energy homes have upgraded prefab housing and enhanced their environmental protection level. Zero energy homes require careful consideration so that they're particularly appropriate for economies of scale, industrial procedures and construction speed associated with modern prefab development.

Zero Energy Building Definition

The buildings that produce or provide their energy through sustainable resources are termed Zero Energy buildings. These buildings cause no carbon emissions. In other words, a zero energy building is one in which the energy production output is greater than the energy consumed on an annual basis.

Zero energy buildings can play their role in lessening toxic emissions, therefore we should construct new zero energy buildings and homes to limit energy use and emissions.

Types of Zero Energy Homes

Zero Energy Homes refer to houses that are convenient, healthy and take up less energy.

•    Passive Solar House

Passive houses, otherwise called Passivhaus structures provide great outcomes, i.e. maximum energy efficiency. A passive solar house utilizes the sun’s beams to warm the home from the inside. The roof is positioned at 45 degrees to fully utilize the daylight striking the building. Thick concrete blocks are used to make the walls of this home. These concrete blocks absorb the sun's beams and emanate them back into the room. Natural light gets into the home through enormous windows.

A passive house can utilize around 90% less energy than an ordinary house. They do require warming yet substantially less warming than a standard house in a similar environment.

•    Radiant Barrier Home

A radiant barrier is a material set between the interior and exterior wall surface. This keeps heat from getting away through the external wall. Radiant barriers are utilized related to most other passive solar techniques.

A radiant barrier lessens the luminous heat transfer from the interior roof to the other sides of the attic. Radiant barriers usually work best when they are opposite to the radiant energy that is hitting them.

There are many different choices available for radiant barriers. It is generally a reflective material, mostly aluminum foil complied with supporting material. The backing materials can be plastic, Kraft paper, cardboard or OSB. It's vital to put a radiant barrier where it will remain adequately warm to avoid the barrier going to the dew point temperature.

Solar Hot Water Heating System

A solar hot water heating system is another option for traditional water heating systems. Solar hot water heating system absorbs thermal energy from the sun and utilizes it to warm up the water. The components forming a solar hot water heating system usually include:

•    A controller system

•    Collectors

•    a backup heater

•    a heat exchanger

Warming up your water straight from the sunlight is significantly more efficient than changing sunlight into energy that is afterward consumed to heat your home’s water.

The users of solar hot water heating systems have witnessed a 90% reduction in their water heating bills. This shows that not only is the solar hot water heating system highly efficient, but also a great saving partner.

How to Achieve Net Zero Energy

To achieve net-zero energy, maximization of building energy efficiency can be done generally taking into account:

•    Air Conditioning

•    Renewables

•    Heating

•    Ventilation

•    Soft Costs

•    Glazing

•    Lighting

•    The Walls and Roof

•    The Building Usage

All these factors come together to attain the objective of net-zero energy. However, a highly insulated and firmly sealed building envelope is a vital part of attaining net-zero energy.

By mounting outdoor lighting installations straight into the ceiling, you can use them for both outdoor and indoor reasons. An appropriately insulated R38 roof would be decreased by a huge amount if there were no lighting installations fitted by any means. However, fitting only one set of can lights could essentially expand the insulation worth of the roof.

A tight construction blower door test estimates how much air that holes out of a structure when exposed to a standard 50 Pa of pressure. To make an extremely close envelope, good glue is usually used on the edges of the wood frame before they're fixed together.


The cost of an average sized family home is approximately $240,000 while the cost of average net-zero energy is approximately $263,000.

By using two methods, you can reduce the cost of your net-zero home. These methods are i) energy modeling ii) small size house

•    Energy Modeling Methods help in selecting the most budget friendly appliances, materials and energy-saving approaches. Energy modeling is a procedure of recognizing the most cost-effective energy-saving elements. With energy modeling, you can evaluate the effects various design options have on a house's energy consumption.

•    Make A Small Size Home: Constructing a compact house is one of the effective ways to have a net-zero home more budget friendly. In the United States, average houses are around 2,400 square feet in size.

Energy Efficiency and Savings

 A net-zero home gives an annual bill of $0. This figure alone indicates that a net-zero home enables you to save more. Apart from being energy efficient, a net-zero home also generates renewable energy. As a result, the house is a self-sustainable structure that releases no carbon emissions into the environment. Zero energy homes can save up to 90% of the energy requirements in comparison with conventional homes. That means that with a zero energy home, you can save thousands of dollars.

Smart Investment Option

One of the best things about a zero energy home is that it doesn’t have to be costly or difficult to build. It is a brilliant way of prefabrication since it decreases the chance of expensive errors while giving a high-quality product. The builders are at ease while building a zero energy home and can customize the design of a house without the zoning regulations concerns.

Final Thoughts

Net-zero homes can be extremely advantageous since their main aim is to utilize less energy, which as a result gives lower energy bills. If you want to have an energy efficient home and increase your savings, then a net-zero energy home can be a great solution.
