IntroductionWithout proper design technologies and practices, the increase in temperature coupled with the increase in sea levels will never change. The main reason for this judgement is the fact that the building sector is contributing enormous amounts of greenhouse gases. The production of these gases is because of the increased energy usage in buildings without provision of the necessary precautionary measures. However, technology has improved remarkably and there are various renewable energy technologies with far less consequences on the environment.Therefore,it is important for any building designer to consider the environmental effects of the energy consumption of the building.Design of the hotelBuildings are designed for comfort and safety. Considering comfort, heat losses and gains are a major factor[ CITATION Att12 \l 1033 ]. The comfort of any building will be determined by the heatcontrol measures taken to ensure that the heat gains and losses are within the desirable range. As a matter of fact, there should be proper ventilation measures to ensure proper air flows because air is the major controller of environmental and building temperatures[ CITATION Wol00 \l 1033 ]. The determination of all these heat gains is demonstrated in the following design of a major hotelin glascow.The hotel has a bed capacity of 250 and has a conference room as well. However, considering that this hotel is at the heart of Glasgow, the rooms must be of deluxe sizes (from 500 sq. feet to 1000 sq. feet).As in our design example, we will consider a room size of 600 square feet (55.74 sq. meters)The weather data for the whole year is indicated below

Therefore, the number of rooms =250 The area of the room =55.74sq.meters.taking the rooms to be square where the length=width=7.4meters. However, the height may be taken as 3.5 meters. We will take that the building has two windows per room each window 2.5m=length=width.The lighting system can be designed in such a way that the artificial lights are on from 1600hrs to 0800hrs.therefore, the duration of lighting per day=16 hours which totals to 5376hours per year.
In this particular case, the illuminance required may be approximated to that of a dwelling whichcan be approximated to 100lux
