Assessment is based on a combination of completing all assignments and sitting for a final short one and a half hour exam, in your own location.
If you don’t cope well with exams then you may elect to undertake a project instead. This is a popular option.
In addition, most modules have a Set Task at the end of each lesson placed before the assignment. This is an opportunity to undertake practical work to help you acquire knowledge and skills and practical experience. This ADL feature is an added bonus not found at most online schools. Set Tasks are not required for assessment.
Some courses also have optional Self-Tests which are available on our online learning platform. These are not available by correspondence or by USB, and do not form part of your overall grade.
How our courses work
- Choose Your Learning Method
You choose how you would like to receive your course material, i.e., Online, USB or Correspondence. The choice is yours. You may also work on online or offline.
- Tutor Allocation
Every student is assigned their own dedicated tutor who is an expert in their subject area. They provide as much or as little individual contact as you require. You can contact your tutor whenever you need – your hours are not limited.
- Feedback and Assignments
Tutor Feedback is an essential component in helping you understand the subject matter. Tutor feedback is given in the form of notes written on the assignment. We encourage you to contact your Tutor where help with clarification and understanding of course material may be required.
Your assignments are located at the end of each lesson. You submit them for marking whenever you are ready. There is no time limit.
- Set Tasks and Self-Tests
Most modules have a Set Task at the end of each lesson before for the assignment. This is where you get the opportunity to undertake practical work to help you acquire knowledge, skills and practical experience. Many modules also have short Self-Tests.
Once all assignments have been completed you may then elect to sit for a one and half hour exam in your own location. If you prefer not to take the exam you do have the option to undertake a project instead.
Once the exam or project part of the course is completed, your Certificate is then processed. Please allow approximately 4 weeks for this.
- Design Your Own Qualification
ADL offers students the flexibility to self-design their own qualification – bundling together a combination of 100-hour modules into a qualification higher than a certificate.

For a 100 hour module many students will take up to 3- 6 months, others take less time and some are even longer. It’s all up to you. There is no pressure to complete or deadline to finish. Naturally, longer courses will take more time.
Q. What learning formats are there?
A. Your enrollment comes with the Online Classroom study option by default. For a small additional cost you also have the options of USB or Correspondence.
USB: Your course is sent to you on a USB stick, so that you can carry it in your pocket. Ideal for those with unreliable internet connections. This option is an additional £5/module
Correspondence: You download the course content and then print your own copy to your requirements. You can then bind the lessons to suit your needs.
Q. Assessment – how does it work?
A. For each 100 hour module you are assessed by assignments (at the end of each lesson) and a final one and a half hour exam (or you may elect to complete a project instead of sitting the exam) – the choice is yours – you sit for the exam in your own location, or you can visit us in Canterbury, England to sit the exam if want to. Exam fees are included in the tuition fee you paid. You can read more about the examination process here. At the end of each lesson, there is an assignment. You submit it to the academy who then submits it to the tutor for marking, comments and feedback. Our policy is to have a grade for you within 5 to 7 days.
Q. How many assignments do I need to complete for each module?
A. At the end of each lesson, there is an assignment – so if a course has say, 10 lessons there would be 10 assignments. The number of lessons per module varies from module to module. See the course content from our website for further details.
Q. When do I have to hand in my first assignment?
A. There is no deadline for handing in the first assignment. Submit when you are ready. There are some students who hand in assignments within the first couple of weeks of enrolment – while there are others who submit their work 6 months later. It’s all at your own convenience to suit you. Everyone has different work and home commitments and we cater to these needs.
Q. I am having difficulty attending workshops/industry meetings, what can be done?
A. If your course requires attendance at workshops, conferences, or industry meetings; alternative arrangements can be made in your country; however, there may be an additional expense. We can appoint an appropriately qualified person anywhere to work through curriculum documentation supplied by us, to satisfy the requirements set down in a course.
Q. What qualification will I receive?
A. For individual modules, you would receive a Certificate (providing you complete all assignments and the exam). If you just want to complete the assignments only, then a Letter of Achievement would be awarded. For more details on qualifications awarded please click here.
Q. Is there a next level to progress to?
A. Yes – you can progress from one module to a combination of many modules and to higher qualifications i.e. Advanced Certificates, Diplomas and Higher Advanced Diplomas. Read more about course levels here.
Q. Can I customize my diploma/higher qualification?
A. Not all educational institution’s certificates /diplomas meet everyone’s needs. The opportunity to design your own diploma at the Academy (subject to our approval) is an added bonus, not found at other colleges. It’s a very popular option and widely used by many students. You quite simply choose the appropriate number of related modules needed to complete the qualification and submit them to us for approval as a custom diploma.
Q. What do I get when I complete the course? Will I receive a transcript?
A. At the completion of a 100-hour Certificate course and providing all assignments and exam have been completed, you will receive a Certificate and Transcript. The Transcript will list your GPA. Each 100-hour module is worth 3 credit hours.
Q. Do I have to sit for an exam?
A. Exams are optional but need to be undertaken in order to receive the Certificate or higher qualification. Exams are one and a half hours long. You appoint an adjudicator (subject to our approval) to supervise the exam. You sit for the exam in your own location. Its that simple.
Q. I don’t cope well with exams – what can I do?
A. If you feel you don’t cope well with exams you may elect to undertake a Project (set by the tutor) instead of sitting the exam. Many students prefer this option as they find researching the material for the project sharpens their research skills.
Q. If I don’t sit for the Exam do I still get a qualification?
A. If you don’t sit for the exam but complete the project alternative, you will still receive your endorsed qualification. If you don’t sit for an exam or complete a final project, providing you have completed all the assignments you will be awarded a Certificate of Achievement.
Q. Do I have to sit for the exam at the Academy?
A. No – whilst you are more than welcome to come to our location in Canterbury, U.K. and sit the exam in our classroom; the more popular option is to sit for the exam in your own location. You appoint an adjudicator to supervise the exam. Click here for more information on that process.
Q. Our tutors – who are they?
A. We only employ tutors who have are currently active in their industry with at least 5 years of real-world experience. Not only are they highly qualified but also experienced, knowledgeable, and professional- experts in their chosen fields from all parts of the world.
Q. Can I contact my tutor at any time?
A. Yes- you have unlimited access to tutors. We strongly encourage students to develop a dialogue with their Tutor. This is why we encourage students to submit their first assignment fairly quickly at the beginning of the course.
Every Academy student is assigned a tutor who supports you throughout your course and beyond. Your tutor is there to guide and facilitate your learning and provides as much or as little individual contact as you would like.

Excerpt From The Course
HEATING AND COOLING
People are more comfortable and less physically stressed in an environment where the temperature is neither too hot nor too cold. Temperature regulation is in fact one of the main reasons why we create and inhabit buildings.
There are two obvious ways to control temperature in a building:
- One is to seal it off from the outside world
- The other is to heat up or cool down the inside as required.
Sealing the inside of a building however can have serious negative side effects: oxygen levels drop and the quality of air we breathe is not as good.
If a building is to remain a healthy environment, and temperature regulated at the same time; you should try to avoid sealing the building. Always try to maintain ventilation. This is covered in more detail in the following lesson.
Principles of Temperature Control
- Supply heat at the same rate it is lost to maintain temperature (To minimise heat loss, reduces need for heating). Heat is lost by conduction (through walls & roof), infiltration (warm air being lost from house) and radiation (heat radiating from warm objects inside the house)
- Central heating system is more efficient than localised heaters
- Localised heaters are cheap to purchase but more expensive to run
- Emergency heaters (back ups) are desirable
- Air circulation and distribution of heat source points is critical to even temperature control
- Air fans to distribute hot air are sometimes used.
- Thermostat should be at height & approx positioning to reflect the temperature where the occupants of the building are to be found
- Heat requirement is reduced by installing sound insulating principles during the design process.
- Cooling is affected by: opening doors & vents; exhaust fans; evaporative coolers
- Exhaust fan placement is important when walls are less than 15ft apart, fans in adjacent walls should alternate should not be opposite.
Temperature can be controlled in buildings in several ways:
- The sun will warm the building during the day. This effect varies according to the time of year, time of day and the weather conditions that day. The way the building is built and the materials used in construction will also influence the building's ability to catch heat from the sun, and hold that heat.
- Heaters can be used to add to the heat in a building. The heater must have the ability to replace heat at the same rate at which it is being lost to the outside.
- Vents and Doors can be opened to let cool air into the building, or closed to stop warm air from escaping.
- Insulation can be installed to give greater control over temperature loss and retention.
- Coolers (blowers etc) can be used to lower temperature.
- Exhaust fans can be used to lower temperature.
PASSIVE SOLAR DESIGN
The use of passive solar design is maximised by efficient engineering and architectural design practices. By the use of orientation, ventilation, thermal mass, insulation and glazing/shading we can design for heating, cooling, storing and control of temperature. Not only does this make our houses more comfortable, but it can dramatically reduce our power requirements. In fact it is recommended that before installing any alternative energy systems it is best to first consider what use can be made of passive solar energy and design principles to minimise our energy needs.
When considering passive solar design for a house or any particular building, it must be taken in context with the immediate surrounds and the general climate of the location. For example, features installed for a house in Canada would differ greatly that for one in Asia.
Solar Design Principles
- Orient the building with the longest side running east to west.
- In cold climates there should be as much window as possible on the north facing wall (in the southern hemisphere) /south facing wall (northern hemisphere) so as to catch the sunlight. There should be minimum windows on the other three sides. Obviously in hot climates this would be inappropriate.
- Insulation in the walls and roof will prevent heat loss in winter and heat gain in summer.
- To gain the best affect cover windows with either close woven curtains or close fitting blinds enclosed at the top by pelmets.
- Use deciduous trees to shade north facing (southern hemisphere)/ south facing (northern hemisphere) windows in summer.
- Eves and outside blinds can aid shading of windows in summer when the sun is higher in the sky.
- Drafts should be minimised by weather stripping. Heat loss through outside doors can be minimised by using air lock/ entry rooms.
Solar Space Heating and Cooling
Whether a building needs heating or cooling will depend upon its location and use. In cool climates heating can be achieved by:
- solar heating combined with thermal mass to prevent overheating and to store heat for release in the evenings. For example, glass that faces north, well sized eaves and slab floors to act as thermal mass can all be incorporated.
- trombe walls utilise a system of having a glass window on the outside of a solid masonry wall the sun heats the wall during the day from which heat is released during the evening, and warmed air (from the cavity between glass and masonry) is circulated into the building.
In warm climates cooling can be achieved by:
- a raised and vented section of the roof can act as a chimney for heated air to rise and escape.
- solar powered fans
- wide verandas shade windows and walls
Passive Solar Design
Passive solar heating can be achieved first in the design process of a building by consideration of the latitude, the sun’s elevation and the site.
Building orientation: dependent upon hemisphere, building orientation is best aligned in a north/south alignment to maximise the incoming solar energy as required. Rooms that are most frequently used/heated should be aligned on the sun side (south in northern hemisphere, north in southern hemisphere.
Awnings/Windows/Skylights: By careful placement of awnings, it is possible to allow winter sunlight to enter the rooms thus providing free heating and to then block the summer room to prevent unwanted heating. This also applies to window and skylight placement. Appropriate placement of deciduous trees which lose their leaves in winter but provide summer shade is also highly recommended and can reduce up to approximately 20% of heating and cooling costs. Glazing can also greatly affect heat loss through windows, as will window shape, placement and control over windows.
Thermal Mass: Thermal mass assists in maintaining a constant temperature inside a building by the ability of certain materials to absorb, store and then release heat. This ability generally increases with material weight. For example: mud brick, rock and bricks have a high thermal mass than timber cladding. Note that poor use of thermal mass can exaggerate the worst temperature fluctuations in the building, it must be used with care and in combination with other features. It can work very effectively in locations with a large variation between day and night temperatures. Basically for thermal mass to work well it needs to be exposed to solar radiation during winter where it will absorb the heat and later release it keeping the building warm, during summer it needs to be shaded from incoming solar energy thus keeping the mass cool, this can be achieved by use of awnings, overhanging roof and shade trees.
Water has the highest thermal mass followed by concrete, sandstone, compresses earth blocks and rammed earth.
Heating using Fuel Sources
Once consideration to minimising heat loss and maximising use of solar heating opportunities, attention can also be given to the best fuel source for heating.
Options include gas, coal, oil, grid electricity, wood and bio-fuels.
