The house is also designed with energy-saving measures; In other words, the way the house is designed makes it easier for us to save resources.
(1) Consumption reduction is a simple concept, but it is difficult to implement because it is behavioral in nature.
10kW grid connected photovoltaic (PV) system to offset the consumption of electric vehicles and houses.
This home can not only enable us to live a carbon free life, but also improve our adaptability in times of uncertain energy costs and availability.
The energy we use for this house includes the sun for heat (solar heat) and electricity (photovoltaic / solar photovoltaic).
The key system backed up on the grid interactive photovoltaic system is 20kW solar thermal system hot water and space heating seasonal thermal energy storage floor radiant heating and cooling and ground loop heat exchange energy recovery fan (ERV) Ground loop preheating and aftercooling solar greenhouse cellar toilet and garden rainwater storage and distribution healthy indoor air quality environmental protection materials and high-efficiency electric vehicle plug-ins (3) renewable energy ￠ when the building is as efficient as possible, using renewable energy to maximize the use of natural energy for power generation is simpler and cheaper.
However, heating in this way allows us to maximize the efficiency of the heat storage system and use ground source energy to cool our house through the floor at a perceived temperature (i.e.
This provides deep flexibility by allowing us to have key housing functions indefinitely without the power grid.
They are integrated into the building; One for seasonal storage and the other for high temperature DHW heating.
The practice of passive housing provides a good framework to achieve this goal.
An e-book: zero carbon building standard 2 edition, please give the official account of green building energy saving direction reply key words “I want to get books”.
Both the sun and the earth’s resources power the automation system, but windows, doors and thermal mass also allow us to manually use cool night air to passively remove heat from the house.
Passive housing provides this.
In summer, the ground cooled water will pass through the heat exchanger to remove heat from the incoming air and partially dehumidify it.
The large solar collector array will provide heat for DHW and radiant floor.
We also use the earth’s heating and cooling energy.
Indeed, in most cases, it is difficult to justify the additional cost of floor radiant heating in houses built according to the passive housing standard, and the floor does not necessarily provide the feeling of “touch warmth”.
We have been trying to reduce consumption and make use of the limited resources provided by the environment to improve efficiency.
For most new homes, there are still many things to reduce energy and resource consumption.
This is what we did in this project: passive design starts with a very high level of insulation and air tightness, and then combines the principle of passive solar energy.
We chose both: the grid connected system will generate more power than the house and our electric vehicle (2012nissanleaf), while the grid interactive system will supply power to key systems such as well pump, solar thermal system, heating and heating system.
The earth is also used to provide heating and cooling energy for the ERV and the overall cellar.
The built-in function can not only return our home’s carbon footprint to zero; They will produce energy for transport and assist in the production and storage of food.
only one pump, not an energy consuming heat pump).
(2) Improving efficiency is similar to reducing consumption, which can explain why many people confuse the two.
Although consumption reduction is about choosing not to use or use less, we believe that efficiency is to meet a given demand with less resources: energy, water, etc.
The careful layout of the room helps to provide natural lighting, and the piping system will reduce the waste of energy and water.
Windows and frames with R10 overall insulation value can provide comfort even on winter nights when ordinary windows are too cold to sit next to them..
The electrical disconnect switch will de energize circuits with phantom loads from electrical appliances, lamps and electronic equipment.
Properly designed large-scale recycling centers will make it easier to transfer waste from landfills.
A healthy and comfortable house} efficient buildings with high-performance windows and proper shading provide incredible comfort.
The house is heated by radiant floor and poured with concrete.
Today, we will introduce a case of zero carbon building, which will provide us with a zero carbon lifestyle that we have been committed to for many years.
In general, we firmly believe that the three-step approach to carbon emission reduction is to reduce consumption, improve efficiency, and finally generate electricity from renewable energy.
One of the characteristics of our family is its large thermal energy storage container.
The battery can be incorporated into the grid interactive system (regarded as an off grid system using the grid as a backup).
Between them, there will be enough energy in summer and autumn to increase the collector, so that the house can spend the winter without using any external energy (especially carbon)! The system is even large enough to provide additional heat in spring and autumn to heat a small greenhouse to extend its growing season.
The temperature of the root cellar will be regulated by the earth (cooling or heating, depending on the season) and naturally ventilated.
Heat energy can be obtained from the earth and the sun.
The grid connected photovoltaic system can generate electric energy to offset the consumption.
Focus on what we are learning as close as possible.
In winter, the grounding loop system will preheat the incoming fresh air.
Public and multi-purpose rooms will reduce building area and cost.
DHW (domestic hot water), ERV, refrigerator, freezer, some lights and some small plug loads, such as battery charger.
If we don’t grow our own food, the excess heat can be used to heat the swimming pool (which is not planned).
