CASE-STUDY: M-build<strong>in</strong>g at Lund University - LTH<br />

Akademiska Hus<br />

Akademiska Hus is the company that owns M-build<strong>in</strong>g and therefore is<br />

responsible for build<strong>in</strong>g’s energy management. This company is owned by the Swedish<br />

government and is one of the largest property companies <strong>in</strong> <strong>Sweden</strong> with more than<br />

3.2 million square meters. The ma<strong>in</strong> bus<strong>in</strong>ess of AH is leas<strong>in</strong>g their properties to<br />

educational and research <strong>in</strong>stitutions. With a 64% of the market share is the ma<strong>in</strong><br />

provider of premises to colleges and universities. Teach<strong>in</strong>g and laboratory premises<br />

are the largest proportion of floor space with and 82% of the total surface (Akademiska<br />

Hus 2010a).<br />

The assessed market value of their properties was 49497 MSEK <strong>in</strong> 2010, more<br />

than 535 M€. The rental revenue was 4983 MSEK, around 540 M€, and the net<br />

operat<strong>in</strong>g profit was 3134 MSEK 340 M€ approximately (Akademiska Hus 2010a).<br />

In terms of energy the total consumption of build<strong>in</strong>gs owned by AH was more<br />

than 900 GWh per year <strong>in</strong> 2010. This is around the 1.89% of the total energy<br />

consumption <strong>in</strong> the services sector <strong>in</strong> <strong>Sweden</strong>. Of this 900 GWh per year more than<br />

400 GWh where used as electricity, around 400 GWh as heat<strong>in</strong>g and approximately 70<br />

GWh <strong>in</strong> cool<strong>in</strong>g systems. Per square meter, the total energy use was 241 kWh/m 2 , 112<br />

kWh/m 2 <strong>in</strong> electricity, 110 kWh/m 2 <strong>in</strong> heat<strong>in</strong>g and around 19 kWh/m 2 <strong>in</strong> cool<strong>in</strong>g<br />

systems (Akademiska Hus 2010b).<br />

<strong>Energy</strong> and water supply expenditure were 650 MSEK <strong>in</strong> 2010, this was 69% of<br />

the total operat<strong>in</strong>g cost of the company. This is an average of 203 SEK/m 2 per year.<br />

Figure 5 shows the distribution per f<strong>in</strong>al use. The ma<strong>in</strong> part of the energy cost is due to<br />

electricity consumption, about 390 MSEK. Heat<strong>in</strong>g costs were 217 MSEK while cool<strong>in</strong>g<br />

costs were 20 M SEK (Akademiska Hus 2010a).<br />
