  2. Passive solar building design - Wikipedia

    en.wikipedia.org/wiki/Passive_solar_building_design

    These systems require good drainage systems, movable insulation, and an enhanced structural system to support a 35 to 70 lb/ft 2 (1.7 to 3.3 kN/m 2) dead load. With the angles of incidence of sunlight during the day, roof ponds are only effective for heating at lower and mid-latitudes, in hot to temperate climates.

  3. Lift slab construction - Wikipedia

    en.wikipedia.org/wiki/Lift_slab_construction

    Lift slab construction (also called the Youtz-Slick Method) is a method of constructing concrete buildings by casting the floor or roof slab on top of the previous slab and then raising (jacking) the slab up with hydraulic jacks. This method of construction allows for a large portion of the work to be completed at ground level, negating the ...

    Please help improve it to make it understandable to non-experts, without removing the technical details. ( February 2024 ) ( Learn how and when to remove this message ) The cooling load temperature difference (CLTD) calculation method , also called the cooling load factor (CLF) or solar cooling load factor (SCL) method , is a method of ...

  5. Concrete slab - Wikipedia

    en.wikipedia.org/wiki/Concrete_slab

    Without insulation, concrete slabs cast directly on the ground can cause a significant amount of extraneous energy transfer by conduction, resulting in either lost heat or unwanted heat. In modern construction, concrete slabs are usually cast above a layer of insulation such as expanded polystyrene , and the slab may contain underfloor heating ...

  6. Underfloor air distribution - Wikipedia

    en.wikipedia.org/wiki/Underfloor_air_distribution

    UFAD systems use an underfloor supply plenum located between the structural concrete slab and a raised floor system to supply conditioned air to supply outlets (usually floor diffusers), located at or near floor level within the occupied space. Air returns from the room at ceiling level or the maximum allowable height above the occupied zone. [1]

  7. Building envelope - Wikipedia

    en.wikipedia.org/wiki/Building_envelope

    The difference can be illustrated by the fact that an insulated attic floor is the primary thermal control layer between the inside of the house and the exterior while the entire roof (from the surface of the roofing material to the interior paint finish on the ceiling) is part of the building envelope.

  8. Insulating concrete form - Wikipedia

    en.wikipedia.org/wiki/Insulating_concrete_form

    Insulating concrete form or insulated concrete form (ICF) is a system of formwork for reinforced concrete usually made with a rigid thermal insulation that stays in place as a permanent interior and exterior substrate for walls, floors, and roofs. The forms are interlocking modular units that are dry-stacked (without mortar) and filled with ...

  9. Voided biaxial slab - Wikipedia

    en.wikipedia.org/wiki/Voided_biaxial_slab

    By reducing the weight of the slab without compromising its structural strength, it is possible to create a thicker slab to support more weight over a longer span. Hollow-core slabs , also known as voided slabs, initially appeared as one-way elements in Europe during the 1950s, and are still commonly manufactured in precast form for ...
