Key Areas

The course serves as a introduction to common HVAC systems. Heating, cooling, ventilation and water systems are all covered including important legislation. It reviews principles and provides knowledge and awareness of how and why, many different mechanical building services systems are designed, operated and maintained.

Course Content

Many people find themselves needing to deal with mechanical building services but have not necessarily received training in mechanical services. Engineering services in buildings are complex and often account for more than 40% of the capital cost of a building. Increasing demands to conserve energy and improve environmental performance mean that good design, efficient operation and reliable maintenance of services have never been more important. An understanding of the issues and their engineering background is exactly what this course intends to achieve.

Day One - Heating

Session 1:

  • Heat Transfers in Buildings: How heat is lost from buildings
  • How to reduce energy use and calculation of building heat loss
  • Abrief review of the latest Building Regulations.

Session 2:

  • Ventilation
  • The increasing importance of ventilation heat loss
  • Fresh air requirements & provision of passive cooling.

Session 3:  

  •  Heating Systems
  • A review of the advantages & disadvantages of the different types of heating system.

Session 4:  

  • Plant Sizing and Controls
  • Energy Trends
  • Boiler Sizing
  • Effective & efficient controls & types of control system.

Day Two - Cooling and Air-Conditioning

Session 1:   Heat Gains & Assessment of Cooling Loads

  • How to calculate a cooling load
  • How to reduce cooling & plant requirements.

Session 2: Air Conditioning Systems

  • A review of the different a/c systems available & their relative merits
  • Latest Developments

Session 3: Types of equipment and standards of use:

  • fans
  • filters
  • heat exchangers
  • humidifiers

Session 4:   Refrigeration

  • Understanding how refrigeration works
  • the refrigeration cycle
  • plant & equipment
  • the issues associated with refrigeration systems

Day Three - Water Services

Session 1: Hot & Cold Water Services:

  • An explanation of different water service systems including current developments.

Session 2:   Legionnaires Disease

  • Explanation of Legionnaires Disease;
  • consideration of its wider impact on Building Services Engineering
  • professional responsibilities

Session 3: Drainage

  • A brief overview of the principles and design of above and below ground drainage systems

Session 4: Building Regulations

  • A review of the significant impact of the latest building regulations

Learning Outcomes

  • Knowledge of a wide range of different HVAC systems
  • Understanding of different system types
  • Awareness of how the services integrate with building performance
  • Appreciation of technical terminology (jargon!)
  • Legislative Requirements

Who Should Attend

The course is ideally suited to those who:

  • have been given additional responsibility for mechanical engineering services
  • have responsibility for estates and engineering personnel or contractors.
  • are Facilities Managers with overall responsibility for buildings and their services.
  • are specialist in another branch of engineering but find they now have to understand mechanical services systems (for example Electrical Engineers, part of a multi-discipline team).
