Office Energy Environmental Services & Construction/A Report On The Energy Consumption And Carbon – Coursework Example
A Report on the Energy Consumption and Carbon Emissions of an Office Building Introduction Firstly, since the infiltration rate of the building is 1 acph, it is too low, so the water is contained at the walls for a long time leading to poor thermal performance. The concrete flows and the concrete slab roof are not insulated; hence this leads to poor retention of heat. (Bryce, R., 2008.) The efficiency of the boiler is not good enough to be used to heat the whole floor (100%).
The building is situated at a very cold area. Therefore, the whole floor needs to be heated. A part from that, each and every room must receive warm air as well as hot water for use.
The hot water requirements are 6 W/m2 needed for 1000 hours/year. The installed office equipment load is 9 W/m2, and the installed lighting load is 18 W/m2 of floor area. Softwood timber, double glazed windows, and doors have a U-value of 3.3 W/m2K. Therefore, the annual space heating for the building is approximately 40 W/m2.
Since the building is occupied by only human beings, the amount of carbon dioxide produced will entirely come from them. The amount of carbon dioxide produced by one person per day is 2.3 pounds (1kg). Therefore, there is 175kg of carbon dioxide emitted from the building in each single day.
The building should be given artificial ventilation by using very small spaced wire mesh situated at the highest points. The densities of the bricks and blocks should be reduced to allow for high rate of infiltration. This will increase the thermal performance of the building. Insulations should be provided for the floors to prevent heat loss and retain much heat in the building. The a bove precautions will greatly reduce the a mount of energy needed for space heating.
As mentioned above, the amount of carbon emissions per day is 175kg, therefore, annually it a mounts to 63875kg.
Apart from improving on the insulation in the building, I would prefer the use of heat pump systems. This is because they can provide for both heating and cooling. Furthermore, they give out more energy than the ones they consume. Thermostats and ducts should be installed because they help in saving energy by switching on and off when necessary the heat sources.
