BRIEF*

INTRODUCTION TO THE PROJECT


Active building

Energy defining architecture

Low energy consumption

Production of it’s own energy

A healthy and comfortable indoor environment

An optimized relationship with the local context

Requirements : 600m² to 800m² in 2 levels. The building must include teaching facilities and 2- 3 apartments for visiting lectureres / businessmen.

FIRST ACTIVE HOUSE- “HOME FOR LIFE”, AARHUS DENMARK

MOISTURE CALCULATIONS - ROOF




Steel roof with ventilation gap

1ST LEVEL PLAN


CLASROOMS ARE DIVIDED BY MOVABLE

WALLS SYSTEM WHICH ALOWDS TO INCREASE ROOM SIZE WHEN THERE ARE MORE STUDENTS

TECHNICAL ROOM IS EXPOSED TO VISITORS BY A GLASS WALL

2ND LEVEL PLAN


THERE ARE OPENINGS WHICH ARE MADE IN

ORDER TO GET NATURAL VENTILATION AND LIGHT WHICH REACHES THE 1ST LEVEL OF THE BUILDING

SECTION 1


WE HAVE RAISED PART OF THE BUILDING IN ORDER TO GET NATURAL VENTILATION AND LIGHT THROUGH BOTH LEVELS OF THE BUILDING

SECTION 2


DETAIL DRAWING - ROOF


THERE IS 500 MM OF OVERHANG TO

CREATE SHADING ON THE FACADE

250 MM OF INSULATION IS USED

TO KEEP THE COOL AIR INSIDE THE

BUILDING

DETAIL DRAWING – STORY PARTITION


WALL IS MADE WITH 250MM

OF INSULATION TO STOP HEAT COMING INTO THE BUILDING

DETAIL DRAWING - WINDOW


THERE ARE USED TRIPLE GLAZED WINDOWS. SPACES BETWEEN GLASS LAYERS ARE FILED WITH CRYPTON GASS .

GLASS PANEL EXTERIOR COATING IS MADE OF POWDER – LACQUERED ALUMINUM PLATING.

U – VALUE FOR PANEL IS 0.44

DETAIL DRAWING - DOOR


SEALANTS ARE USED TO AVOID LINE LOSES

DETAIL DRAWING - FOUNDATION


INNER PANEL OF WALL IS

LOADBEARING OUTER LAEF IS MADE FROM SPECIAL RENDERING WHICH DOESN’T CRACK

DURING DRYING PROCESS AND THE FINAL FINISH IS LAYER OF PAINT

VENTILATION


Fresh air needed

Canteen 78m2 x 5.6 ls/m2= 436.8 l/s 1572m3/h

Class rooms 135m2 x 4.21 ls/m2= 567 l/s= 2041m3/h

Rooms 51m2 x 3.5 ls/m2= 1785 l/s= 642 m3/h

Offices 32 m2 x 1.41 ls/m2= 5.2 l/s= 18.6 m3/h

Hall ways= 125 m3 x 3 ls/m2= 375 l/s= 1350m3/h

Total of fresh air needed= 5623m3/h

Second proposal

Canteen 78m2 x 4 ls/m2= 436.8 l/s 1123m3/h

Hall ways= 125 m3 x 1.5 ls/m2= 375 l/s= 700m3/h

Total of fresh air needed= 4524m3/h

Extraction needed

Bathrooms 11x15 l/s=165

Kitchen 40 l/s

Storage 20 l/s

Total 225 l/s=810 m3/h

Need for cooling- classes

70 people – 700w

70 pc – 4200w

Light – 1350w

Total = 12550W =>572m3/h

Actual ventilation =680 m3/h- Comfort class B

KEY NUMBERS (Be 10)


The Be10 calculation program gives us the overview on the

buildings energy consumption during the design phase. When looking at these results we have to take into consideration that there is no input data that has the climatic details of Ho Chi

Minh City. Therefore we have used the climatic details of Hanoi. The program will continue to improve in the future, but we can

say for sure that it is an ACTIVE HOUSE. If we had more data, this would have been clearly seen.

SOLAR CELLS


Solar Cells

Chosen company – Kyocera Solar Weight of Cell – 25kg

Dimensions – 1600 x 1270mm Maximum power of one chosen cell - 0.315 kWh

Slope of the Roof – 2 degree Slope of the Cells – 10 degree Orientation – South

Approximate average amount of kWh for house (light, appliances and etc.) – 6 kWh – 12h

Approximate amount of kWh for ventilation – 9 kWh – 12h 15 kWh / 0.315 = 47, 62 ~ 48 panels should be placed on the roof.

• KEY PRINCIPLES OF ACTIVE HOUSE: INTEGRATION OF ENERGY USAGE, CLIMATE & DEMANDS FOR COMFORT WHICH

MAKES IT SUSTAINABLE AND USES MODERN TECHNOLOGY • USES SOURCES FOR ALTERNATIVE ENERGY (GEOTHERMAL; SOLAR) • COMPACT DESIGN • TAKES ADVANTAGES OF THE ENVIRONMENT AND TERRAIN (WIND; GROUND; VEGETATION) • ENERGY PERFORMANCE, CONCUMPTION AND SUPPLY IS IMPORTANT ISSUE • THE BEST SOLUTION FOR THE SPECIFIC CONTEXT • DAYLIGHT & THERMAL CONDITIONS ARE FACTORS WHICH EFFECTS THE WELLBEING AND ABILITY TO PERFORM

ACTIVE HOUSE IS NEAR FUTURE IN ALL OVER THE WORLD. CULTURAL THINKING AND TRADITIONS NEED TO BE PUSHED A SIDE TO MAKE THE IDEA AND THE TECHNOLOGY DEVELOPMENT FASTER.

CONCLUSION*

THANK YOU!!
