Heating, ventilation and air conditioning (HVAC) is the technology of indoor and vehicular environmental comfort.

Its goal is to provide thermal comfort and acceptable indoor air quality.

HVAC system design is a subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics, and heat transfer.

Refrigeration is sometimes added to the field's abbreviation as HVAC&R or HVACR, or ventilating is dropped as in HACR (such as the designation of HACR-rated circuit breakers).

A kitchen is a room or part of a room used for cooking and food preparation in a dwelling or in a commercial establishment.

In the West, a modern residential kitchen is typically equipped with a stove, a sink with hot and cold running water, a refrigerator, counters and kitchen cabinets arranged according to a modular design.

Many households have a microwave oven, a dishwasher and other electric appliances.

The main function of a kitchen is serving as a location for storing, cooking and preparing food (and doing related tasks such as dishwashing), but it may also be used for dining, entertaining and laundry.

A bathroom is a room in the home for personal hygiene activities, generally containing a sink (basin) and either a bathtub, a shower, or both.

In some countries, the toilet is included in this room, for ease of plumbing, whereas other cultures consider this insanitary, and give that fixture a room of its own.

Lighting or illumination is the deliberate use of light to achieve a practical or aesthetic effect.

Lighting includes the use of both artificial light sources like lamps and light fixtures, as well as natural illumination by capturing daylight.

Daylighting (using windows, skylights, or light shelves) is sometimes used as the main source of light during daytime in buildings.

This can save energy in place of using artificial lighting, which represents a major component of energy consumption in buildings.

Proper lighting can enhance task performance, improve the appearance of an area, or have positive psychological effects on occupants.

A toilet is a sanitation fixture used for the storing or disposal of human urine and feces.

In developed countries, different forms of porcelain flush toilets are common: seats are usually used in the West while squat toilets are common in East Asia.

These are connected to a sewer system in most urban areas and to septic tanks in less built-up areas.

In many developing countries, especially in rural areas, dry toilets such as pit latrines and composting toilets remain common.

Dry toilets are usually placed in outhouses, i.e. not inside the dwelling, and are ideally located away from sources of drinking and bathing water.
