Environmental Science and Services
Assessment task details and instructions
By focusing on a pseudo client brief this assignment will focus on the following major aspects of a Services project:
Heating Systems;
Ventilation Systems and
Domestic Hot Water Services.
Young and Simpson have been working with the university to develop initial design ideas for the building and the point has been reached where they can be used to begin to examine the possible building services systems that might be included in the completed design. The outline plan for this building along with other useful information is included in appendix 2 of this brief.
You work for the building engineering services consultant George Smith and Co. who have been appointed to carry out initial services designs for the project.
Activities
1. Provide an introduction that clearly explains the relationship between building engineering systems and the needs of occupants and users.
2. Heating Systems
Carry out the following.
The office space within this building is to be maintained at a room temperature of 21°C critically analyse what combination of heating system and type of heat emitters might the most suitable to achieve this condition. The discussion provided must be justified.
Based on a design building heat loss of 50 W/m2 calculate all room heat losses, determine the building heat loss and select an appropriately sized gas fired boiler, or boilers, for the whole building. Present your calculations as a tabulated schedule.
3.Ventilation Systems
When considering the means of providing ventilation within a building there are essentially two options:
Mechanical air handling and
Natural ventilation.
Compare and contrast the relative merits of both of these options with respect to functionality and sustainability, select a suitable ventilation system for the building and clearly explain why you feel the system is the most appropriate.
4. Domestic Hot Water System
Explain what is meant by centralised and de-centralised domestic hot water systems and subsequently select an appropriate method of providing domestic hot water to the Catering and WC provisions.
