BUILDING DESIGN2IntroductionThe building sector is changing remarkably with the design and construction of buildings taking considerable effort to reduce the energy consumption as well as decrease the greenhouse emissions. However, there are various types of buildings for various purposes such as residential,industrial etc. Therefore, the design engineers should ensure that the design does not alter the usage while still maintaining the efficiency[ CITATION AlH05 \l 1033 ]. The following is a design that focuses on the energy input and output of a building that serves the purpose of a hotel as well as a conference. The building has 12 floors and the capacity of 250 beds.DesignElectricity usage for a single room (assuming all the rooms are the same)In our design, we will consider lighting of rooms as the main energy usage for the building. However, because there is the natural light as well as artificial lamps, the lighting hoursmay be between 1800 hrs. And 0800 hours=14 hours per day, 7 days a week and 48 weeks a yearTime that the lights are used=14 7 48 =4704hrs/year The floor area to be illuminated=37.162 square meters

BUILDING DESIGN3The lighting data will determine the electricity usage for a single lamp. Taking a 100w incandescent GLS lamp with an efficacy of 18l/W and taking the illuminance of a dwelling which is about 150lx.Also taking a light loss of 50%.

BUILDING DESIGN4Installed lumens=37.162 150 10050 =11148.6lumens Input power=11148.60.619 /18 1000lumenskWroom therefore the total electricity consumption=0.619250 =154.84kWThe heat losses from the buildingThe standard hotel room is estimated as 400 square feet (37.1612 square meters). The heat loss from this standard room mainly occurs through radiation from the walls to adjacent rooms and to the environment[ CITATION Per00 \l 1033 ]. Heat loss can also occur through windows and as such, a good estimation can be obtained from the energy necessary to warm this room[ CITATION deS13 \l 1033 ].
