In passive house design, the cost savings that result from dispensing with the conventional heating system can be used to pay for the upgrading of the building envelope and provide renewable energy heating. If you are planning to build your own passive house then it is essential that you know as much as possible about passive house design. Passive houses are very well insulated, virtually airtight, buildings which minimize energy loss and improve occupant comfort. Passive house design considers the entire life-cycle of the building and uses a variety of ‘passive’ building solutions to eliminate conventional ‘active’ technologies that consume wasteful fossil fuels. รับสร้างบ้านสระบุรี
Passive Solar Design
Passive solar design is specifically used to exploit free energy from the sun, to provide warmth. A passive house is orientated so that large south facing windows absorb energy from the sun. The rooms are laid out so that the solar heat is distributed from these windows through the interior of the home. The process of capturing the solar energy is considered to be ‘passive’, since the building does not generate the energy itself. The heat energy comes from a natural source and is not generated exclusively by artificial means.
Provide Thermal Mass
Passive house buildings can be constructed from either dense or lightweight materials. In the case of lightweight construction, like timber frame, some internal thermal mass is incorporated. Thermal mass allows dense construction materials, typically concrete, stone, brick or tile, to store the free heat. During the day, when external temperatures are highest, a large thermal mass inside the insulated envelope will absorb the sun’s heat. When the external temperature cools down in the evening, the thermal mass will naturally radiate that absorbed heat throughout the rooms.
Install Super Insulation
Insulating the building envelope is one of the most important passive house measures as it has the greatest impact on energy expenditure. In the average house, well considered and expertly installed insulation can reduce the amount of heat lost through the building envelope, by at least half. In addition, a high standard of thermal insulation will considerably improve thermal comfort for the building occupants.
