ABSTRACT
In this Case Study, We will extract previous work, which includes an analysis of a Sample House
located in Sapanca/Dibektaş village. In the first section you will see geographical orientation of the
house, using Google Earth, upcoming sections there will be statistics about Annual Climate
Characteristics of the region and Temperature Graphs can be seen . The Climate type of the region is
CFa, Altitude : 40Mt., Average Annual Temp: 14,3C, Average Rainfall : 740 mm. Upcoming Sections
there will be Simulation program trials on E-Quest and first two simıulations because of missing
input data, such as not possible to upload local Climate conditions, not selected Electric & Gas
Company, there was a limited output can be seen according to limited inputs. Additionally in this
Case study, we tried to locate similar charecteristics especially around 40th
parallel in US. We have
found some candidate cities such as Pittsburg, but since the rainfall characteristic and other
specifications is not matched it did not reflect %100 precise information. Howewer we made a
second work to understand output accordingly.
Regarding E Quest, we used 3 design wizard Scenarios , and dimensions of the building can be seen
realistic in upcoming sections. On the other hand, since we have limited options during the selection
of the insulation material, roof etc. parameters will not reflect %100 our sample and simple village
house. Although we’ve got some idea to focus on material usage on the house, since we have options
to concrete and wood.
In the 2nd
. Simulation we had a chance to observe some outputs which helped us to understand deeper
information about E-Quest Program.
In the 3rd
simulation, we’ve used only local conditions files, cooling and heating loads of the chosen
building for two different Wall Material selection.

1. INTRODUCTION
In our mid Term Report, we were studying on a Simple Village House located
near Sapanca Lake, Turkey. In the study basic construction information about this
building was given.
This Study is continuing to work on the Same Area/Building, next Section we’ve
added detailed Climatical information, Temperature graphs and rainfall
analysis,annually.
Also we will make three simulations for similar Structured Buildings which is
created on E-quest, and Compare their Design Wizard Steps.
Our Aim is understand the program capabilities, reportings and how we can get
help using defined design parameters, not only dimensions or Climate Data also
how we can use predefined and standardized information before decide to make
some work in our houses, or Business place.
In the last section, we used only Cad drawing of the House, and used Sapanca
Original Climate files which is directly imported to the E-Quest program,
followings steps we calculated “U” values of the building according to TS825.
And in conclusion part, we managed to compare two different materials in the
same conditions to understand differences in terms of Cooling & Heating analysis.

Below steps and parameters as chosen to import our Sample House in the program to
evaluate simulation about given options :
STEP1
Figure8. Source E-Quest
8. 8
Since our House is a Basic Family House, 2 floors, we try to avoid wrong options to create
far from our real building. In States options there are to many options helps to shaping our
simulation such as Code Analysis, Jurisdiction, Location (Especially in US Wheather files
comes automatically), And Electric, Gas Authorities with their usage profile tarrifs,
We have chosen “No Cooling” since our old building hasn’t got any HVAC equipment,
also Furnace meaning old style Cheminee, or Stove. Daylight Control and Usage details are
blank because of the same reason.
In STEP3, We have chosen the roof type, and Orientation according to Google Earth Data,
Also all dimensions entered by guessing, since we did not have Architectural Drawing of
the House. All Dimensions based on assumptions used site seeing experience.
According to dimensional calculations, we have found our Building area 276 ft2 for each
floor.
(Since some missing inputs we did not have Step2 Data)
IN STEP 4 we have chosen Wood Standart Frame, which was the closest option to our
original construction Technic “Bagdadi”, also Ext. Finish we have Chosen “Clay tile” and
Color “Orange” which represents most closest to original one.Above Grade Walls we had
STEP3:
Figure 9. Source E-Quest

STEP4:
Figure10. Source E-Quest
chosen Concrete, which represents most closest to original Stone, also gives a logic to our
case study during the comparisons between different structures in terms of “Life
Cycle”Since our Building is very Simple and Primitive, we did not select any insulation
material which represents modern technics. Regarding Ground Floor design, we’ve selected
“Earth Contact” and interior finish has chosen Carpet with Rubber Pad. Which is very
commonly used in traditional Turkish Houses.
According to our observations from Site Seeing, we have chosen 6” Construction for Grade
wall. And No Wall insulation material has chosen.
Infiltration data comes as a result :Perimeter 0,038 CFM/ft2 /Ext. Wall Area
Core 0,01 CFM/ft2/Floor Area
10. 10
STEP5:
Figure11. Source E-Quest
IN STEP5, We have chosen internal finish Lay-In Acoustic Tile, and Framing Wood –
Standart Framing. No insulation has been chosen. In the Ceilings, try to linked original
conditions, as a result we have chosen Plaster Finish, In the Vertical Walls, we have chosen
Frame. In the Floors section as same in previous screen we continued to Carpet with rubber
pad. And 4 in. Concrete chosen for the floors.
11. 11
STEP6
Figure12. Source E-Quest
IN STEP 6, we have chosen 1 Opaque door which reflects best according to original status
of the Sample House. Door Orienteation also selected South East. Door Dimensions has
calculated 6ft.x7ft. Wood, Hollow core Flush, 1-3/8 in.
IN STEP7, we selected percentage of Net Wall Area, Selected Glass Categories Double,
Guardian, and Sun-Guard SN-68 Clear/Air/Cleat , Wood/Vinyl, Fixed in 1,30 in. Wide.
Window dimensions is chosen according to observations by 3,33ft x3,33 ft. which brings us
to %18,5 window ratio (Flr-to flr), and net %24,7 (flr-to-ceiling)
IN STEP8, Since the Sample House hasn’t got any Shading over Window, we made it
blank.
IN STEP9, we did not place any Skylight which doesn’t exist in the original Sample either.
Between Steps 10-12 is not shown due to missing data..
IN STEP 13, We’ve Selected Activity areas as much as simple, since we have an
Abondened single Space Floors House, can be only guessed what it used to be.
IN STEP14, We’ve selected Lighting Areas of the rooms with some assumptions
Step 15 is not shown due to missing data.
IN STEP 16, We’ve selected none for all Unoccupied Zones
IN STEP 17, Since our Building using as a Family House, we’ve selected full occupation.

Figure20. Source E-Quest
IN STEP 19, Since we do not have a Cooling System it is not selected, As Heating, because
of limitations in the menu, we’ve selected Gas Furnace System which is closest to our
Chosen Sampe House’s configuration.
STEP20:
Figure21. Source E-Quest
IN STEP20,We have chosen fictive Cooling and Heating Setpoints of the House, to
understand how to respond, in reality this old house has no intelligent control.
IN STEP 21, We have Chosen 225 kbTuh for Heating.
IN STEP24, Output came out 1.107 SqFt Served as a result of previous selected
parameters.
IN STEP 25, we have chosen al days, and off very rare.
STEP26 has not shown due to missing data
IN STEP27, No Base Board has been selected.
IN STEP 28, No Hot Deck Resets has been chosen.
STEP 29-35 has not shown due to missing data
INSTEP 36 Has no Residential Domestic Water Heating.
INSTEP 37, Residendital Domestic Heating is none.

In the and off all results because of missing data we did not get a Healthy result about our
building.
In Order to make a Comparison, we’ve made another model, as much as similar
characteristics chosen a place in the US.

As seen Above, in the 8th
Step, we did not put Shades in this Scnerio either.
28. 28
Figure38. Source E-Quest
As you can see in 9th
Step, Also did not choose Skylights.

Figure41. Source E-Quest
In 15th
Step, Area Type is chosen, Religious Worship because in our original Sample House
has no separated room inside, and this was the only option among the buildings.
Figure 42. Source E-Quest
In Step17th, different than previous Scnerio we’ve selected some inputs which creates
some value to analyse.

In Step 50th
To understand the Gaps, even we did not select Heating and Cooling, there has
been Gas charge here..
After Step 50th
, Simulation Tool has generated below figures :
Figure51. Source E-Quest
According to above Table we have a chance to analyse Electrical Consumption Data
annually of the Model we’ve simulated.
And Additionally since we have Climate information loaded address base, and regulations
according to Geo Code, we have also Roof Insulation Data.
In Addition, all below Reports are available depend on the Analysis Point :

Figure52. Source E-Quest
As you can see above capture, since we did not selected Heating in the second simulation,
although we’ve selected tarrifs of Gas Providers, result appears “zero”.
Figure53. Source E-Quest
Above Graph gives us Annual/Monthly Utility Bill for Electric and Insulation.
Figure 54. Source E-Quest
Above Graph reminds us how limited parameters we’ve mentioned during the design, that’s
why only Area Lighting and Exterior Usage can be seen.

Even, placed limited data, because of Selected Defined materials provides us information
about lifecycle costs.

5. E-QUEST ANALYSIS- SIMULATION 3 ACCORDING TO TS825
In this simulation, we’ve created another file, with more presize information as well as
dimensions of the building also original Climate Files :
Figure61. 3rd
simulation- Source E-Quest
We in this Scenerio, we’ve skipped all the steps which was chosen in the previous
scenerios, and only floor, door, window placements and dimensions entered correctly.
Below figure gave us the base inputs before we start Heat Load, and Cold Load of the
building, which is wall thickness and components:
42. 42
Figure 62. Wall material
According to Wall structure, we’ve calculated simulation results considering 50cm.
Thickness of the wall, and this thickness includes 5cm. Roughcast from inside and outside,
10cm Timber and 20 cm. Stone.
When we wanted to go “U” Value calculation:
1/U=Ri+Re+R (w/m2K) (Ri:0,13, Re: 0,04 )
And each “R” value :
R = d/ʎ (R: Heat transmission resistance, d:Thickness of Construction Material, ʎ:Heat
Transmission value)
Using tables from TS825 we’ve found our values :
R= d1/ʎ1+d2/ʎ2+d3/ʎ3
d1/ʎ1=0,2/0,2 =1
d2/ʎ2=0,3/2=0,15
d3/ʎ3=0,1/1=0,1
if we put the values in place :
R=1+0,15+0,1=1,25 than,
1/U=0,13+0,04+1,25 =1,42
U=0,7 W/m2.K
43. 43
If we convert the value to BTU and F :
U=0,123 Btu/hft2F
After we’ve calculated this value we moved directly to the related reporting in the E-Quest,
and here below Heat Load-Cool Load Analysis of Scnerio 3 Building:
Figure 63. Source E-Quest
44. 44
If we compare seasonal Cooling and Heating loads can be seen below :
Figure64. Heating and Cooling Load results in Graph- Source-Cem LALE
45. 45
Based on these values we also created another material selection to make a comparison
with the previous table, again we used Light Concrete material this time, and selected ʎ for
Light Concrete is : 0,29 (according to TS825)
R : 1,82 and U becomes :0,5 W/m2K, with the same conversion technique we have found :
U=0,088 Btu/h.ft2F
Than second table :

6.CONCLUSION
Here we saw how important to gather trustable information from a standardized system in
order to evaluate them during design. And also all Services connected and transparent ratios
applied world works even with very less data as proved in Simulation 2, a Prayhouse in
Pitssburgh/PA, first idea by doing this to understand with even less data if this system
really produces healthy information.
Why Pittsburg is actually at list tried to stayet with same Line of Longtitude with Sapanca,
which is 40th
.
Figure 67. Source: NASA
And below we look Climate conditions for Pittsburgh:
Figure 68. Source: Climate-Data.org/AmbiWeb GmbH/OpenStreet/Map
When we look at similar works, comparisons between different structures, especially
related in our 2 Simulation Models, Wood and Concrete Forms,
And when we look at Load Anaysis Graphs on the Simulation3, we see seasonal behavior
of the building in Timber and Concrete structure.
48. 48
From Max Cooling Load Light Concrete gives some advantages in summer time, on the
other hand according to regional climate in this case structural performances look very
similar:

and heating load spectrum. –Source – Cem LALE

If we want to understand old buildings specific characteristics to adapt them into new
systems, we need to create a connected infrastructure to give opportunities people,
researchers, building owners to understand their add on to a Greener World.
