Accessibility

Accessibility is the degree to which the built environment is available to as many people as possible. Accessibility can be viewed as the "ability to access". The concept often focuses on people with disabilities or special needs and their right of access. Accessibility is not to be confused with usability.

BASIX

BASIX is the Building Sustainability Index which is used to regulate the energy efficiency of residential buildings. It rates the expected performance of any residential development in terms of water efficiency, thermal comfort and energy usage. It aims to reduce water consumption and greenhouse gas emissions by 40% compared to pre-BASIX (2004) buildings. To be granted development approval, each development application must carry a BASIX certificate.

BCA

BIM

Building Information Modelling is a process involving the generation and management of digital representations of physical and functional characteristics of a building. BIM extends beyond 3-D, adding time as the fourth dimension and cost as the fifth dimension and therefore covers more than just geometry. It also covers spatial relationships, light analysis, geographic information, and quantities and properties of building components. BIM offers enormous time savings, far greater accuracy, and the avoidance of error, alterations and rework due to information loss.

Land and Environment Court

A court established by legislation giving it exclusive jurisdiction to hear and determine environmental, development, building and planning disputes. If a project is refused by a Council, or if it fails to determine a development application, a client may choose to take the council or the decision to the court for appeal or to gain an approval.

Latent condition

A term that is described in a building contract similar to the physical conditions on or affecting the site that differ from the conditions that should have reasonably been anticipated by a competent builder at the time of commencement of the contract.

Passive Design

Passive design is a design method that reduces or eliminates the need for any mechanical or electrical cooling or heating in a building. Design methods include natural energy flows to maintain thermal comfort, orientation, insulation, air tightness, natural light, thermal mass, solar gain, and natural ventilation. Passive design is the antithesis of active design which requires systems to maintain thermal comfort such as air-conditioners and other equipment (including solar panels) that create energy and therefore comfort.

Renewable energy certificates

Renewable Energy Certificates (REC's) are available when buying qualifying solar hot water, solar/wind power systems or solar panels. Cash back's on purchases are received by selling the REC's. From 1 Jan 2011 REC's were reclassified as large-scale generation certificates (LGCs) and small-scale technology certificates (STCs).

Revit

A 4d Building Information Modeling (BIM) program used for the design of buildings. It allows users to design a building and its components in 3D, annotate the model and access building information from the building model's database. Revit has tools to plan and track various stages in the building's lifecycle, from concept through construction and then to demolition.

RFI

Request For Information. A formal request from a builder that describes required information in order for the builder to continue to build.

RL

Reduced Level. A surveying term that describes the height of an item in relation to a datum, commonly the Australian Height Datum (AHD).

R-Value

R-value is a measure of resistance to heat flow through a given thickness of material. The higher the R-value, the greater that resistance. It is a common measure when specifying insulation in a building. The R-value suited to any building depends on the particular climate in which it is located. R-values can be measured depending on the direction of heat flow. "Upward" or "up R-values" is resistance to upward heat flow, (also called winter R-values) and "downward" or "down R-values" is resistance to downward heat flow (also called summer R-values).

Section 94

Section 94 of the Environmental Planning and Assessment Act (NSW) provides that, if the consent authority is satisfied that if a development is likely to increase the demand for public amenities or public services in the area, the authority may require the applicant to make a financial payment and/or dedicate land free of cost as a condition of approving the development.

Solar Energy

The radiant energy of the sun, which can be converted into other forms of energy, such as heat or electricity.

Solar Hot Water

top

Thermal comfort

The condition of the mind that expresses satisfaction with the thermal environment and is assessed by subjective evaluation and includes factors such as temperature, humidity, sources of heat (e.g. computers) and clothing. Thermal comfort is maintained when the heat generated by human metabolism is allowed to dissipate, thus maintaining thermal equilibrium with the surroundings.

top

U-Value

A U value, or thermal transmittance, is the rate of heat loss or transfer in a building element such as a wall, floor or roof. It is also referred to as an ‘overall heat transfer co-efficient’ and measures how well parts of a building transfer heat. The higher the U value the worse the thermal performance of the building envelope and conversely a low U value indicates high levels of insulation.
