Energy efficient buildings are important for reducing environmental damage from excessive resource use. Building designers should focus on maintaining optimal indoor temperatures, maximizing natural light, conserving water usage, and ensuring good airflow. Effective insulation is key. Energy efficient materials include polyisocyanurate foam, adobe construction, plastic composite wood, structural insulated panels, and autoclaved aerated concrete. Homeowners can make existing homes more efficient by improving insulation, using energy efficient appliances and lights, incorporating smart technology, and cleaning regularly to minimize wasted energy. While initial costs are higher, energy efficient buildings save money over time through reduced usage.

1. Energy Efficient Building

2. Energy Efficient Building is the Future
of Our Planet
• Efficiency in energy becomes a major global
concern at the moment. The earth has quickly
exhausted its resources due to the ever growing
human population and industrialization.
• In the construction sector, people are trying to
come up with the most energy efficient building
design. More responsible practice like this is
hoped to reduce damage to the environment.

3. How can buildings be more energy
efficient?
• There is one concept that people need to adhere to if
they want to build an energy efficient building. It is
about design consciousness.
• The builder must design the building that specifically
caters to energy efficiency. There are many ways to do
that.
• The parts that you need to pay attention to are:
– Maintaining the temperature in the building.
– Getting as many natural lights as possible.
– Conserving water in the building.
– Maintaining good airflow within the building.

4. What building material is most energy
efficient?
• Finding energy efficient building material is the
more pressing task for the builders. The building
material plays a significant role in the building
process.
• It is because the materials chosen for the building
can determine how efficient the building will be
operating.
• Additionally, the building materials also need to
be energy efficient even during the production
process.

5. Materials that are considered to be
energy efficient
• Here are some construction materials that are
considered to be energy efficient:
– Polyisocyanurate foam
– Adobe construction or compressed soil
– Plastic composite wood structured
– Structural Insulated Panels
– Autoclaved aerated concrete
– Plant-based polyurethane rigid foam
– Straw bales

6. How can I make my house more
energy efficient?
• If you want to make your house more energy efficient, you can
employ the following strategies:
– Paying attention to the insulation
You need to make sure that you pay the most attention to the
insulation. As mentioned before, temperature is one of the biggest
issues to tackle inside the house. Poor insulation can result in the
house not being in optimum temperature most of the time. That will
make the energy used to maintain the house at livable condition a lot
bigger.
– Purchasing materials and equipment with certification
Homeowners can also ensure that their house will be energy efficient
by purchasing materials with certifications. International certifications
are given to materials that have been tested and known to conserve
energy. They also follow ethical practices in the production stage.

– Using energy efficient lights
Lighting is one of the biggest factors that differentiate an energy efficient building with the
more energy wasteful building. LED lights are currently popular because it does not take too
much energy to run them. It can save up to 75% energy compared to traditional technology.
– Incorporating the appropriate ventilation system
The airflow in your building also determines the energy use. Your home design needs to make
sure that the air circulation occurs smoothly. A good air circulation can control the
temperature inside the house. It can also prevent molds from forming inside which can cause
health problems in the long run.
– Using environmentally friendly energy sources
Some houses already try to use more environmentally friendly energy sources. The current
trend is to install solar panels as the partial or sole energy source. Solar panels are great
because they use the sun to draw power. It requires less fuel and produces less waste to the
environment.
– Low-flow water system
The water system inside the house also needs to be more efficient. Low-flow water system is
recommended because it can disperse water effectively despite using significantly less water.
Many modern houses have installed it and renovating a house to include this system is not
difficult.

8. How do I know if my house is energy
efficient?
• You can check if your house already adheres to the
energy efficient building design by doing an energy
audit. This audit can decide the energy flow that goes
in and out of your house. This information will provide
the gists about where the house stands in terms of
efficiency.
• There will be an expert who will come to the house and
inspect the whole system. The person will inspect
plumbing, electric circuits, and other components. This
audit process can show the homeowner which parts to
be improved so that energy efficiency can be
maximized.

9. What are 5 ways to save energy?
• Homeowners can conserve energy using these five approaches:
– Buying appliances that are energy efficient
Appliances that you buy must be energy efficient. There are many new technologies that
companies come up with to make their products consume less energy. Usually, these products
are certified by an international board.
– Using smart technology
Smart technology is not only convenient but also efficient. With the smart technology, you can
automatically turn on and turn off your switch. This system is really helpful, especially for
people who tend to be forgetful.
– Lowering energy use consciously
To support the energy efficient building, the occupants must adjust their lifestyles too. It can
be by doing more conscious practices such as unplugging unused appliances. You can also
reduce your showering time.
– Fixing damage quickly
Damages in the building must be fixed quickly. It can be leaking faucets or drafts in some of
the caulking. These small problems can grow into bigger ones. Even balancing the house
condition with those small issues can drain a lot more energy.
– Cleaning home regularly
You may not think that it would be helpful. However, cleaning the house regularly will prevent
the house structure being damaged as dust and other small particles tend to be responsible
for it. You should also clean the appliances regularly.

10. How is energy wasted in homes?
• Energy can be wasted inside a house in various
ways, such as:
– When the user leaves appliances plugged into the
chord.
– Leaving lights on when unused.
– Taking too long hot showers.
– Cooking elaborate meals that use many appliances
often.
– Not replacing the water filtration system regularly.
– Setting the air conditioner too high or too low.

11. What is one disadvantage of
becoming more energy efficient?
• There is a disadvantage of creating an energy
efficient building. It is the added cost of the
cutting-edge appliances as well as a person
who understands green design.
• The materials to build these buildings are also
more expensive because they are not as
mainstream as the other kinds of materials.
