Overview of Services

22 Degrees designs mechanical, electrical, hydraulics and fire protection building services. Clients have the option of using one, two, three or all of our services. The benefits of an integrated approach to design include convenience, time and cost saving, improved communication and better understanding of the project as a whole.

Our 22 Degrees team works side by side on each project, covering all building service requirements. But whether we undertake an integrated approach or provide a core service within a cross company project team, we ensure there is close co-operation and communication across disciplines.

We also provide a range of consultation services such as reviews, analysis, recommendations, advice at initial planning stage and expert witness services for mediation, arbitration or trial.

We have worked on a number of Green Star projects and provide on-going assessment and management tools for clients. Elements we cover include:

  • Air conditioning & ventilation
  • Plumbing & drainage
  • Gas systems
  • Electrical systems
  • Fire sprinkler systems
  • Industrial & exhaust systems
  • Security systems

  • Pools ventilation and heating
  • Hydraulics design
  • Lighting design
  • Energy efficiency analysis (H1)
  • Thermal modelling
  • Glazing selection
  • Refrigeration
  • ESD
  • Green Star accreditation
  • Due diligence reports
  • Peer reviews


22 Degrees designs building services including heating, ventilation and air conditioning systems with a focus on simple, effective design. A key aim is to have minimal impact on the architecture and structure of a building. Our designs must be energy efficient and specific to the needs of the building not just standard designs that get rolled out. It is important that systems are not over-designed where too complex or large a system is specified and not under-designed where too little allowance is made for future use.

A good design starts with a good plan. We ensure our initial assessment and analysis is thorough and that we are clear on stakeholders’ expectations and outcomes. The 22 Degrees team can assist with the all aspects of a building’s mechanical design including:

  • Air conditioning & ventilation
  • Energy efficiency analysis (H1)
  • Glazing selection
  • Green Star accreditation
  • Industrial & Exhaust systems
  • Peer reviews
  • Greenstar ESD
  • Refrigeration
  • Seismic engineering
  • Solar systems
  • Thermal modelling


Hydraulics expands beyond the traditional scope of plumbing and drainage design to cover a host of other piped services within the dripline of the building. No longer is compliance the only consideration in plumbing and drainage design.

Diverse considerations such as energy efficiency, esthetics and client expectations must be factored into any plan. A thorough understanding of all aspects of the design and intended use of a building is critical along with effective communication with all stakeholders. The 22 degrees team can assist with all aspects of a building’s hydraulics design including:

  • Plumbing & drainage
  • Sanitary waste systems
  • Stormwater drainage
  • Trade waste drainage
  • Rainwater modelling for reuse
  • Rainwater harvesting systems
  • Cold water reticulation
  • Hot water reticulation
  • Gas reticulation
  • Medical gas reticulation
  • Compressed air reticulation
  • Hot water heating plant design
  • Peer reviews
  • Greenstar ESD
  • As-built documentation
  • Siphonic drainage
  • Private pumping stations

Electrical Engineering

Electrical engineering requires exacting standards in design, specification and project management. Diverse considerations such as energy efficiency, safety, aesthetics, varied use of a building, security concerns must be factored into any plan. A thorough understanding of all aspects of the design and intended use of a building is critical along with effective communication with all stakeholders. 22 degrees electrical team can assist with all aspects of a building’s performance including:

  • HV & LV power reticulation systems
  • Power supply analysis
  • Earthing systems
  • Lightning protection
  • Lighting Design: Interior, exterior, landscape, carparks, emergency
  • Specialist lighting designs
  • Security & Access Control systems
  • Data/voice communications designs
  • Structured cabling (telecommunications)
  • MATV
  • PA systems
  • Intercom systems
  • Audio visual system designs
  • Ups, Generators system designs
  • Peer Reviews
  • Greenstar ESD
  • As-built documentation

Fire Protection

Fire protection systems are a key part of a building design, protecting occupant life and owner property. Good fire protection design involves an integrated approach during the critical design period. Our engineers design fire protection systems to enable competitive tenders and to assist architects and developers in ensuring that special requirements are met, without the need for surprises during construction. The 22 Degrees team can assist with the aspects of a building’s fire protection design including:

  • Automatic Fire Sprinklers
  • Automatic and Manual Alarms
  • Building Hydrant Systems
  • Handheld Fire Fighting Equipment
  • Emergency Lighting Design
  • Mechanical Stairwell Pressurisation Design
  • Fire Protection Specifications
