Question

Part 1) Every Space and Entire Building needs to have an air balance, supply air must equal return plus outside air, ventilation air. Ventilation air must have the prescribed outside air quantity, ASHRAE 62, plus the amount of outside air to balance the space exhaust air, plus the amount of air required to positively pressurize the space.

Group of answer choices

True

False

part 2)

External Loads do not influence building internal environment through building components, Building assemblies.

Group of answer choices

True

False

Answer 1

Part (1) .......TRUE

Explanation

Yes, every space and entire building needs to have an air balance, supply air must equal return plus outside air, ventilation air.

American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) and others are including provisions in standards to resolve indoor air quality concerns.

The building codes are a primary institutional mechanism for establishing and enforcing standards for building construction.
The building codes are important for reducing energy use and preserving indoor air quality.

The ASHRAE Standard 62.1 for commercial buildings, and ASHRAE Standard 62.2 for residential buildings are consensus standards and represent the standard of practice for the building industry with respect to ventilation and indoor air quality.

The provision of these standards form the basis for ventilation requirements in building codes, and therefore, these standards are also included.

Part (2) .......FALSE

Explanation

The external loads influence building internal environment through building components because-

The building envelope is the physical barrier between the exterior and interior environments enclosing a structure.

The building envelope comprises of components and systems that protect the interior space from the effects of external environment like precipitation, wind, temperature, humidity, and ultraviolet radiation.

The internal environment comprises of the occupants, furnishings, building materials, lighting, machinery, equipment etc.
