Thermal mass
Materials such as concrete, bricks and stone are high in thermal mass, which means that it is a lag in the time it takes for the material to heat up up and to cool down. The poor placement of thermal in the warmer in winter. The poor placement of thermal cooler in summer and warmer in winter. It is also moderate day between daytime and nighttime fluctuations, making the home a more constant temperature. Mass - as many will have experienced - can create spaces that are too cold (like a tiled bathroom floor on a winter 's morning) or too hot.
Cross-flow ventilation
Cross flow ventilation is a fancy term for your house to naturally cool the spaces. & # 39; Cross-flow & # 39; refer to the approach of placing openings at opposite sides of a room to encourage available breezes to cross evenly through Cross-flow ventilation can be used during summer nights to & # 39; purge & # 39; the If windows or openings on either side of the house can not be opened, the ventilation of the space will be limited.
Solar Dryer
Another fancy term referring to something we have a clothes line! The solar dryer - or clothes line is the natural way to dry clothes. The term is a bit of a misnomer however, because it is actually the wind That's most of the drying, while the sun is responsible for all the fading!
Insulation
A well insulated home will be warmer in winter and cooler in summer and require less less rapid heating / cooling The insulation requirements of the floor. The insulation requirements of your floor. Depend on your climate.
R-value
The larger the R - value, the more insulating the material is. R - values are generally used for insulation products as a guide to how effective the product will be at resisting unwanted heat loss / gain.
Insulated Glazing
Insulated glazing uses two or more panes of glass separated by a thermally resistant spacer to create an air gap between In some systems, a gas such as argon is used in the air gap which further reduces heat transmittance.
Gray Water
White water & # 39;, water water & # 39;, water water sits somewhere is black water & # 39; in the middle of these two extremes and is usually wasted along with black water from the shower, laundry etc.
This is an effective way to save yourself and to flush toilets and use in the washing machine. It is important to investigate ways to manage and treat Gray-water and devise a system that best suits your situation and needs.
Grid-connect PV
PV stands for Photovoltaic. A grid-connect PV system is a solar electricity generator that is connected to the existing power grid. Small-scale PV systems can be installed on you roof. The benefits of this type of system can be produced a lot of energy, the system will feed excess energy into the grid for use by other homes, businesses etc.
Many energy companies are essentially reverse your power savvy suppliers will actually pay you a premium for the energy you give back, meaning you can experience significant reductions in your electricity costs - maybe even a credit! When the sun sets or on cloudy days when the PV system is not enough enough energy to meet the demand from your home, you seamlessly starting drawing power back from the grid, meaning you will never be without electricity, even during the dreariest seasons !
Passive Design
By utilizing many of the features designated above, a passive house will be warmer in winter and cooler in summer. Key features of a passive design are:
- Climate responsive design
- Orientation to the North (or South in Northern Hemisphere) to maximize solar gain in winter
- Adequate shading to prevent overheating in summer
- Appropriate insulation to reduce unwanted heat loss / gain
- Good access to ventilation to allow for natural cooling and temperature control when available
- Thermal mass, appropriately located to help moderate the temperature
This absolutely saves money on heating and cooling costs as well as being an ecologically comfortable, more comfortable environment for occupants.
