My aim with this report is to investigate the building’s energy strategy and explain the theoretical basis behind the mechanical design process. The report considers the following design problems:
Flow rates
Riser sizes
Energy modelling
Building issues
Gains
Novel methods of heating and cooling
Renewable energy alternatives
Part L 2006 building regulations and yearly carbon dioxide emissions
Environmental impacts
The flow rates are estimated with a simple calculation model, and then modelled in Cymap, Heva Comp and ETA to confirm the calculated airflows. The airflows are used in the mechanical design process for the drawings that are issued to the client. The air flows are also used in the part L 2006 carbon dioxide emission calculation. There are two systems; one with a yearly CO2 emission per square meter of 54.00 kg, which is 5.6 kg over the target 48.40 kg CO2/ m2 per year, and one system with reduced airflows with an annual carbon emission of 51.50 kg CO2 per square meter. This is 1 kg under the target 52.50 kg CO2/m2, year. The last part of the report concerns environmental impacts and the moral of buildings using glazing facades.
