  2. Internal energy - Wikipedia

    en.wikipedia.org/wiki/Internal_energy

    The internal energy of a thermodynamic system is the energy of the system as a state function, measured as the quantity of energy necessary to bring the system from its standard internal state to its present internal state of interest, accounting for the gains and losses of energy due to changes in its internal state, including such quantities as magnetization.

  3. Intrinsic and extrinsic properties - Wikipedia

    en.wikipedia.org/wiki/Intrinsic_and_extrinsic...

    In materials science, an intrinsic property is independent of how much of a material is present and is independent of the form of the material, e.g., one large piece or a collection of small particles. Intrinsic properties are dependent mainly on the fundamental chemical composition and structure of the material. [1]

  4. House Energy Rating - Wikipedia

    en.wikipedia.org/wiki/House_energy_rating

    The House Energy Rating (HER) or House Energy Rating Scheme (HERS) are worldwide standard measures of comparison by which one can evaluate the energy efficiency of a new or an existing building. The comparison is generally done for energy requirements for heating and cooling of indoor space. The energy is the main criterion considered by any ...

  7. Home energy storage - Wikipedia

    en.wikipedia.org/wiki/Home_Energy_Storage

    The stored energy commonly originates from on-site solar photovoltaic panels, generated during daylight hours, and the stored electricity consumed after sundown, when domestic energy demand peaks in homes unoccupied during the day. Small wind turbines are less common but still available for home use as a complement or alternative to solar panels.

  8. Passive house - Wikipedia

    en.wikipedia.org/wiki/Passive_house

    In the United States, a house built to passive house standard results in a building that requires space heating energy of 1 British thermal unit per square foot (11 kJ/m 2) per heating degree day, compared with about 5 to 15 BTU/sq ft (57 to 170 kJ/m 2) per heating degree day for a similar building built to meet the 2003 Model Energy Efficiency ...

  9. Invariant mass - Wikipedia

    en.wikipedia.org/wiki/Invariant_mass

    In this frame, which exists under these assumptions, the invariant mass of the system is equal to the total system energy (in the zero-momentum frame) divided by c 2. This total energy in the center of momentum frame, is the minimum energy which the system may be observed to have, when seen by various observers from various inertial frames.
