Learning Outcomes of the 5N4974 Building Services QQI Level 5 Course 

Building services is the discipline of engineering that helps in the achievement of a sustainable, safe, and comfortable indoor environment while minimizing the risks of environmental conditions of a building.

This assignment solution shall cover the key characteristics and properties of materials used for the water, drainage, heating, and electrical systems in a domestic dwelling, installation procedures of such systems, impact of the renewable energy technologies on the building services, symbols, and unit of measurement used for the building services and construction products, etc.

These are the following learning outcomes of the 5N4974 Building Services QQI Level 5 assignment activity:-

Analyzing Characteristics and Properties of Materials used in the Water, Drainage, Heating, and Electrical System in Domestic Dwelling 

Before the construction of the building and domestic dwelling, various systems and services need to be installed such as water, drainage, heat, and electrical systems. The learners shall be able to analyze the materials, characteristics, and properties which are used for the building of systems in a domestic dwelling.

For a connection of drinking water supply in a domestic dwelling, the pipes are used which are different from the ones which are used for carrying the drainage water. Some of the common materials used for the water supply pipes in the dwelling are galvanized steel with a zinc coat, copper, PVC, CPVC, iron, and stainless steel.

While for a drainage system in the dwelling the different pipes like the soil pipe, vent pipe, rainwater pipe, wastewater pipe, and anti siphonage pipe must be used. A wide range of heating systems is used for heating the buildings and a central heating system is used for the dwelling.

There is also renewable heating system like water source heat pumps, solar thermal panels, biomass boilers, ground-source heat pumps, and electric heaters which are used. The materials used in these heating systems are iron chrome aluminum alloys, iron chrome aluminum PM grades, and nickel-chrome alloys with different properties of these elements that must be studied by the learners.

The electrical system used in the dwelling uses different types of materials which are electricity’s good conductors and insulating. Electrical wires are made up of aluminum, copper, and silver which are great conductors of electricity with distinct properties of such metals.

Learners shall be able to analyze the wide range of materials, their properties, and characteristics which shall be presented in form of a portfolio or collection of work.

Outlining the Procedures for Installing Water, Drainage, Heating, and Electrical Systems in Domestic Dwelling 

The learners shall be able to learn the installation procedures for the water, drainage, heating, and electrical system in the domestic dwelling. For effective drainage system installation tools and materials are required. The subsurface and surface drainage systems can be installed which use either groundwater pipes, interceptor drains, mole drainage, or slotted subsurface pipes.

For the heating system, the heat pumps need to be installed and before doing so a home survey needs to be done by an appointed person who can identify insulation measures. Heat pump installation in the dwelling must be done only when it is airtight and insulated. The heating system can be either Space Heating Zone or Domestic Hot Water Zone.

For central heating, the boilers and radiators and laying of pipes, and control system installation must be selected. A certified contractor needs to connect the boiler to the gas supply and for installing the central heating system on the gas boiler.

• First the equipment used for the heating should be researched.
• A map should be created for such a heating system in a dwelling.
• Important parts to be installed.
• Install the radiators.
• Laying pipes from such radiators.
• Installing the control system.
• Shutting water and gas supply for installing a boiler.
• Finally installing a central heating system.

While installing the electrical system in a domestic dwelling one needs to design a wiring diagram, and install conducts, and the circuits. The learners shall present their learning outcomes in the form of a collection of work at regular intervals.

Outlining the impact of the Renewable Energy Technologies on the Design of Building Services 

The learners shall be able to outline the impact of renewable energy technologies on various systems used in the buildings and dwellings. This zero passive building design is very important for the construction of energy-efficient buildings. This shall be followed by the use of low energy building materials and use of efficient equipment and finally integration of renewable energy technologies for application.

The lighting, refrigeration, and heating in the building should be done only with clean renewable energy. The solar passive building techniques before designs are very important for passive heating and cooling. An integrated renewable system can be used for water heating, electrification, and solar photovoltaics.

The use of solar, wind and geothermal energies can be increased which shall make the energy-efficient buildings. This shall be asked by the examiner in the theory-based examination for an assessment of the learners.

Symbols and Unit of Measure with Building Services and Construction Products 

All the building services symbols are drawn in different sizes in accordance to use in the construction industry and the architectural drawings. The blueprint drawings in the building construction use graphic symbols and straight lines.

These graphic symbols are used in building plans which are applied for making gas and water services lines, finishes, floors, windows, door types, etc. The specific symbols are used for electrical companies as well.

The measurement shows the description of quantities, values, cost, and price of construction work. The unit of measurement for the construction depends on the nature, shape, and size of the work. Some of the methods of measuring the unit are- earthwork, backfilling, brickwork, concrete work, tile flooring, stonework, plastering, and painting.

Questions can be asked in the exam related to the symbols and various units of measurement for the construction activities and the building services.

Assessment Techniques for the 5N4974 Building Services QQI Level 5 Course

To display the skills, competence, efficiency, and knowledge of the learners and analyze whether they have achieved their learning outcomes.

The learning assessments need to be undertaken by the learners.

All learning outcomes must be assessed and achieved with the help of the minimum intended module learning outcomes set out in the validated program.

The assessor devises the various assessment instruments which need to be inconsistent with QQI’s assessment requirements.

Assessment Evaluation
Examination Theory – 40%
Collection of Work or Portfolio – 60%

• Examination Theory shows the ability of a learner to recall his knowledge and skills within a set period and application of specific theory and knowledge.
  
• A portfolio or Collection of Work is a collection of work which is in the form of pieces produced by the learner over a certain period providing a clear picture of the learning outcomes of the learners. Such collection may be self-generated or in response to the range of activities devised by the assessor.

Grading System
Pass -50%-64%
Merit -65%-79%
Distinction -80%-100%
