the energy performance certificate of the 
building.
•
To be flexible and easy to use.
•
To  be  used  recursively  in  the  design  of 
new  buildings  as  well  as  in  retrofitting 
practices.
•
To  guide  the  designer  towards  achieving 
higher energy performances with the help 
of explanations related to design decisions 
and feedback, both on legislation and the 
design  decisions  made  for  each  step,  if 
possible.
•
To  evaluate  the  energy  requirements, 
energy  consumption,  primary  energy 
need,  and  accordingly,  CO
2
  emissions  of 
a building.
•
To help design buildings with high energy 
performance and low CO
2
 emissions.
•
To  assess  the  energy  performance  class 
and greenhouse gas (GHG) emission class 
according to consumption data.
Program Structure of EnAd
EnAd is a soft tool for the evaluation of the 
energy  performance  of  residential  buildings 
considering the energy requirements for the 
four energy parameters: space heating, coo-
ling,  domestic  hot  water  and  artificial  ligh-
ting. Heat transfer calculations within EnAd 
are  derived  based  on  EPBD,  Turkish  BEP 
Regulation and the related standards and do-
cuments.  The  general  program  structure  of 
EnAd is illustrated in Figure 2. As in many 
other evaluation programs, EnAd requires the 
selection of location or weather data, building 
form, material properties, and options for ser-
vice systems with a schedule of use.

Data Structure of EnAd 
In  EnAd,  design  decisions  and  factors  af-
fecting the energy performance of buildings 
defined by TS EN 15217

, including thermal 
characteristics  of  buildings,  space  heating,

ventilation, lighting, passive solar heat sour-

,  including  thermal  characteris-
tics of the building, types of heating system, 
indoor air quality, climatic conditions, inner 
heat gain resources and solar radiation form 
the bases of the tool. 
These  decisions  and  factors  are  taken  into 
consideration to produce an outline that will 
form the conceptual structure of EnAd, which 
suggests investigating them under four main 
headings:

Site-related characteristics: Location
•
Form-related decisions: Definition of 
the building form 
•
Construction-related decisions: 
Properties of the building envelope
•
Energy-related decisions: Building 
systems
The second step of the development process 
of  EnAd  is  to  investigate  the  relationship 
between  design  decisions  and  factors  affec-
ting the energy requirement of buildings and 
legislation,  which  includes  directives,  stan-
dards, laws and regulations. To this end, the 
Turkish legislation regarding the energy per-
formance of buildings is reviewed and gro-
uped  according  to  the  design  decisions  as 
shown in Figure 3.
