6.1.2 Energy Performance
The energy performance of buildings should include a general framework
for the calculation of energy performance and the building categories to be
included. Let us consider here the basic recommended method for calculat-
ing the energy performance of buildings [3-10]; it should include at least, but
not limited to, the following aspects:
1. Thermal characteristics of the building (envelope and interior
partitions and so on)
2. Air-conditioning system
3. Ventilation system
4. Hot water supply and winter seasonal heating
5. Built-in lighting installation for commercial sector
6. The building's orientation: its position and outdoor climatic
conditions
7. Passive solar systems and solar protection
8. Natural ventilation (if available)
9. Indoor climatic design conditions
The positive influence of renewable energy sources on the environment
should be included, such as
1. Active solar systems' contribution to domestic water heating based
on renewable energy sources
2. Combined power and heat production
3. District cooling/heating systems
4. Natural lighting with goals to save electricity and cooling energy
Building categories to be covered can include
1. Office buildings
2. Educational facilities
3. Healthcare facilities and hospitals
4. Hotels and restaurants
5. Sporting facilities
6. Department stores and commercial buildings
7. Warehouses, museums, cold stores and so forth
Starting from the contents of the calculation framework and looking at
the currently available European and international standards, Table 6.1
is the simple outcome summary. Preferably, as few calculation models as
