This report has been written to provide information to client Eric Parr, and will advise on the integration of Mechanical & Electrical building services in a 2 storey office building. The building also has basement space available for plant allocation.
The areas which have been requested for consideration are:
Mechanical Heating, Ventilation and air conditioning systems
heat loading Calculating
Fire and Security Systems
Each section will be accompanied by a series of sketch designs showing installation methods and locations within the building.
Evidence shall be used from external sources to strengthen the document.
Reference to proposed building plans can be found in the appendix.

Mechanical HVAC Services
Whether dealing with any building certain services need to be considered at the design stage to enable occupiers have reasonable conditions and a comfortable working environment. HVAC systems (heating, ventilation and air conditioning systems) are used to provide buildings with ‘conditioned air’ which is odourless and fresh, as well as ensuring the temperature, humidity and flow of the air is within a certain comfort range appealing to the occupiers. Figure 1 on page 5 is a diagram which explains a basic design process when designing a heating or ventilation system for a building.
According to the charted institute of building services engineers ‘a successful heating system design will result in a system that can be installed and commissioned to deliver the indoor temperatures required for the client.’ (CIBSE Guide B 2004) a heating service should also be designed to sustain its original performance capabilities over its planned life with little need for maintenance or replacement.
There are two main categories associated with heating systems, these fall under Direct and Indirect.
Direct heating systems consume fuel in the space of the system and heat the air up within the same area. The fuels used for these systems are:
Solid fuels (Wood, Coal)
Indirect heating systems consume fuel from another location (at the source of the system) and the heat energy is transferred within a building through a series of secondary elements (heat transmission mediums) the transfer elements are usually one or mixture of three:
Choice of proposed heating system
The use of an indirect heating system which enables its plant and machinery to be stored away within the building out of sight as the heat is distributed from one location to the desired destinations within a sized building shall be proposed to the client.
The system to be integrated in the design is a low temperature hot water system. (LTHW) A heating system ‘which operates at a maximum temperature of 100 degrees C and a minimum flow temperature of 70 degrees C’ (.Gov.UK.2014) appliances such as radiators, and radiant panels as...
