<p>Abstract</p><p>Climate and environmental issues are of paramount importance. Researchers agree</p><p>that we must all contribute to a reduction of gases that contribute to climate</p><p>change. Energy consumption must decrease within all sectors and the promotion</p><p>of renewable sources of energy must be introduced.</p><p>Each sector should aspire to decrease its energy consumption. Energy</p><p>consumption is strongly linked to waste gases that contribute to climate change.</p><p>Passive houses are a part of the construction industry's methods to attain energy</p><p>conservation.</p><p>Passive houses are derived from low energy houses and super insulated houses. A</p><p>passive house is intended to obtain heat from the inhabitants and through their</p><p>activities. The house is built so that heat losses through the climate shell (doors,</p><p>windows, walls, floors and ceilings) and the ventilation system are decreased. In</p><p>order to get a good indoor environment it is important that the ventilation and</p><p>heat recycling system working together, hold the energy consumption down. This</p><p>is how faculty people usually present a passive house to someone who has not</p><p>considered the concept before.</p><p>I would like to turn the focus from heating to cooling. Houses with large glass</p><p>facades facing south and a closed climate shell risk too high an indoor</p><p>temperature. How do we plan houses so that they don’t need a cooling system? Is</p><p>protection from the sun enough?</p><p>During the planning of a passive house, efforts are made in order to let the house</p><p>be dependent on a small heat battery during the coldest parts of the year. My</p><p>approach to passive houses became an effort to see how solar radiation influences</p><p>closed and highly insulated units.</p><p>The heating of houses in my calculations was not influenced to any extent by the</p><p>rotation of the building. When heating buildings the sun’s radiation only plays a</p><p>small part. When the sun’s radiation is most concentrated no active heating is</p><p>required. It is important to note that solar radiation cannot be depended upon at</p><p>all times especially in winter. Of course, with sun protection, energy needed for</p><p>heating will increase but energy for cooling will decrease.</p><p>Sun radiation influences active cooling as shown in my software program.</p><p>Increased sun radiation requires increased active cooling for alternatives in my</p><p>study without sun protection. The alternatives with sun protection are not</p><p>influenced as much by solar radiation as those without.</p><p>Alternatives with strong sun protections are not as sensetive how the house is</p><p>placed among the point of the compass. Solar radiation does not become equally</p><p>considerable and impact to be decreased therefore.</p>
