2. Roof Types and Orientation
When you’re installing Roof Windows in a project, it’s important to think about the
position of the building and the rooms.
This will have an impact on the type, and number, of windows needed. We would always
recommend a minimum of 20% glazed area to floor space.

3. WORKING OUT WHAT KIND OF LIGHT IS RIGHT.
A South-facing window will capture the most sunlight during the day (morning and
afternoon).
Whereas a North-facing window will receive no direct sunlight at all but it will still
capture a constant weaker light throughout the day.
An East-facing window will catch the rising sun, and a West-facing window will
capture sunlight from early afternoon onwards.
make the most of our windows by placing them in a such a way that they help you
maximise the available light.

5. Sun Tunnel
Natural daylight for windowless areas
Many houses have bathrooms, hallways and other rooms where
daylight only enters when you open the door.
Dim and dark, these rooms are unwelcoming places until you turn
on the light.
Now that has all changed.
Sun Tunnel signals the end of dim and dismal spaces in the home.
Sun Tunnel brings natural light into even the darkest and most
isolated spaces through a specially designed tunnel from roof to
ceiling.
Options available to suit either pitched roofs or flat roofs.

building
a new sustainable building with optimal
balance between energy efficiency,
architectural quality, healthy indoor climate
and good daylight conditions.
The building has facilities for the Dean,
professors and students of the Faculty of
Science at the University of Copenhagen.
1-

9. Daylight, energy and indoor climate
From an architectural point of view the building was inspired
by the sundial and the movement of the sun around the
house.
The design underlines the fact that the sun is an important
topic in science and one of the most significant energy
sources in Green Light building.

10. Daylight in Green Light building
Green Light building is not only a light office when it comes to sustainability.
Vital daylight has been thought into all details.
Daylight is the primary light source in Green Light office and daylight has been
thought
into the very architectonic principal idea itself.
The house is circular and has an internal core, which simultaneously holds the central
staircase, provides ventilation through the natural stack effect and draws a lot of
daylight down through the house from the roof windows.
When you are going to energy optimize a building as it is the case for Green Light
building it is decisive to integrate architecture, materials and light into an overall plan
to obtain an extremely low energy consumption

11. Green Light building has been designed as a deep circular house with an internal
passage of light, which fetches light down into the building from a huge glass covered
hole at the top,
It provides lots of daylight, creates natural ventilation and lets the hot air out,
The stairs utilize the room to its full extent and creates a good, open and clear flow in
the office.
In that way the architectonic and sustainable solutions will be combined.
The daylighting performance of Green Light house has been specified using the
daylight
factor (DF) as performance indicator.
In technical terms, the daylight factor should be at least 3 % in all working stations and
minimum 2 % in hall ways.
This means that daylight is evident in all rooms.
Due to the construction of the automatic window shades, sunlight is reflected deeply
into the building

12. Working in daylight environments results in higher productivity
In Green Light building, daylight is used as an active energysaving strategy.
The building has the ability to function as a daylight lamp,
at all times and in all weather conditions, transporting maximum exterior daylight
into the interior through windows in the facade and the roof.
Together with lux sensors and dimmer controls, the result is an efficient balance
between available daylight and the need for artificial light, which results in minimum
use of electricity.
If the roof windows were removed and the same light levels were to be reached with
artificial light, the need for electricity would be more than four times higher.

13. Energy concept
The sun constitutes the central point and primary energy source of Green Light
building.
The building is 950 m2 and it has been built in accordance with the “active house”
principle, which means that it generates energy.
The building has its own energy supply consisting of an unprecedented combination
of thermal solar heat, heat pumps, seasonal storage, PV solar cells and district
heating.
Green Light building is an energy efficient construction work of high architectural
quality and with a large intake of daylight.
The house is filled with plenty of fresh air deriving from natural ventilation, which
ensures a healthy indoor climate.
By means of the building’s energy design, the building has cut down ¾ of its energy
consumption in relation to Danish building standards.
This means that the building is better than other buildings in Low Energy Class 1
under the EU standards applicable since 2006.
These standards are expected to apply across the EU for all new construction work by
2020.

16. Their architectural design responds perfectly to the difficult conditions of the plot:
a very steep and leafy slope, in partial shade, facing south-east towards the Vienna
woods.
The kitchen and living areas are gathered around a protected, high-quality outdoor
living area facing south-west.

17. Daylight
The use of daylight has been maximised to ensure the health and well-being of the
residents.
the daylight conditions digitally and with the use of a model under an artificial sky to
arrive at an average daylight factor of at least 5 % for all living and working spaces.
This ensures balanced daylight levels through out the two floors and minimises the
need for artificial light.
The location of the windows was planned strategically to give the best view, maximum
passive solar gain and the most efficient natural ventilation and to emphasise the
character of the house.
Shadows cast by the nearby mountain have been countered in the living room by roof
windows positioned high up, which allows light to fall into the depths of the room.
The total window area is equivalent to some 36 % of the floor area.
Direct daylightThe effect of direct daylight on our health is well known.

18. Energy design
The prime objective of Sunlighthouse was to reduce overall energy consumption
(particularly primary energy) to a minimum without sacrificing living comfort.
The features contributing to a positive energy balance include:
• a highly efficient brine/water heat pump
• thermal solar collectors for the production of domestic hot water
• a PV solar cell system for generating electricity
• highly energy-efficient household
Ventilation
Intelligent control of windows will provide primary ventilation in spring, summer and
autumn.
In winter, this will be supplemented with mechanical ventilation with heat recovery.
A comfortable summer indoor climate will be achieved by making use of the stack
effect, night cooling and awning blinds on the windows.
No energy is used for cooling.

21. Modernising old houses
The aim is to combine optimum energy efficiency and the highest standards of
liveability in a home that operates on a carbon-neutral basis.
3-

22. Daylight
Daylight is vital for our biological rhythm and has a positive impact on our well-being
and performance.
Daylighting design played a central role in the architectural concept of LichtAktiv Haus.
It is based on extensive studies conducted by lighting designer and professor, Peter
Andres.
Daylight analyses were used in the early design phase of the project and integrated in
the dynamic process of building planning.
By focussing on the optimal use of daylight, living environments of high quality as well
as good energy efficiency could be achieved.
High amounts of daylight and generous views permit the occupants to fully experience
the daily rhythms and seasonal changes of the surrounding nature
An extension is added, offering space for the living and
dining room, kitchen and utility room

23. Ventilation
Together with shutters and sun screening products the ventilation concept works as
‘natural air conditioning’ and ensures a pleasant indoor climate. At midday, the south-
facing shutters remain closed during the warmer times of the year.
On the western side, the external awnings are lowered automatically in the afternoon.
As the day gets cooler, the shutters and awnings are raised again and windows open to
let in the fresh evening air to cool down the living space.
During the cooler times of the year, raised shutters allow additional solar energy to
enter the building during the daytime.
At dusk the shutters close and improve insulation.

24. Architectural concept
Energy concept
Future buildings should create healthier and more comfortable lives for their occupants
without having a negative impact on the climate.
Therefore, LichtAktiv Haus aims to cover its entire energy demand, including household
electricity, by using renewable energy – without losing any of its high living value such
as daylight and fresh air.

25. Incredible Bamboo Architecture by Vo Trong Nghia
Bamboo is the stuff of green dreams these days.
Not only is it a winning combination of strong, lightweight and
flexible; it also scores highly in the sustainable stakes, being
super fast growing and easy to harvest locally in many parts of
the world.
What's more, it is increasingly being lauded for its aesthetic
qualities. None of this is news to any architect worth their salt –
but one in particular, Vietnamese virtuoso Vo Trong Nghia, stands
out for his exceptional bamboo designs.

26. The rounded bar he designed for his Water and Wind Cafe features a 30-foot bamboo
frame covered in a local bush plant.
Like a giant version of the haystacks that dot the Vietnamese countryside,
it is also African-esque, with a pointed open dome that allows light to infuse the
interior. Elsewhere, Nghia’s curving bamboo structures are bound together with not a
nail in sight.
the architect proved the ideal and natural foundation for what he would learn in the
land of the Rising Sun

27. •Residential house in Shimane
The house is situated in west Japan, in a region that experiences
marked climatic contrasts between seasons.
In summer, there is subtropical heat, while winter is characterized by
icy temperatures and deep snow.
The house is buried in a mound of stone rubble that does not absorb
moisture.
The glazed roof is oriented to the south to maximize solar gains in
winter, while air cavities form a thermal buffer.
When buried in snow, the stones shield the ground floor against
wind and cold, while in summer they maintain a temperature
balance.
It is then that the timber structure comes into its own.
By opening the entrance gates and the glazed sliding elements, the
entire house is cross-ventilated from the patio.

28. SUMER :OPEN + MESH
When the wooden doors and window opened.wind yravels
through the upper and lower floors. Furthermore,the
house copes with temperature and humidity because the
gaps in the wooden roof structure and the crushed stones
are ventilated
Winter :close
When the wooden doors and window are close,
the upper floor becomes an insulating air space above
the lower floor.when the snow is piled up on the
crushed stones,it acts like a snow cave.thus,the main
space of the lower floor is proctected by many
insulating layers of air.

29. CarbonLight Homes are two semi- detached homes.
They are proof that it is possible to build energy efficient, sustainable housing
that is not only pleasant to live in, but also easy to replicate by the volume house
builder.
use of building technology and the exciting way it captures natural daylight
and ventilation to minimise energy consumption.
6-

30. These homes are designed and built to the UK government definition of zero
carbon
and will achieve Level 4 of the Code for Sustainable Homes.
The design of these properties intends to minimise energy use among
residents and generate a sense of community, while advocating a respect for
the environment.
The aesthetics of the scheme are sympathetic to the local context while also
retaining an identity of its own.

31. Daylight
The starting point was to maximise daylight, which has many health and well-being
benefits.
Through extensive modelling HTA have achieved designs with a minimum average
daylight factor of 5 % for the whole house – which is up to three times
greater than that required by the Code for Sustainable Homes in living spaces.

32. Energy design
The homes will achieve a 70 % reduction
CO2
emissions, with the remaining 30 % o, emissions
being offset through an ‘allow a solution’.
The offsetting will be achieved iagreement with the
Local Government office by carrying out
improvements to th energy efficiency of existing
local housing which will more than offset the
remainingemissions from the CarbonLight Homes,
thus surpassing the required 100 % reduction in
CO emissions for the project.

33. Ventilation and heating
The houses are designed in such a way that fossil fuel energy (such as electricity), is
reduced to a minimum.
In the summer, natural ventilation is used for cooling and to create air movement that will
push stale air out as well as bring fresh air in and maintain good levels of thermal
comfort. During the winter, a Mechanical Ventilation system with Heat Recovery is used
in addition to the natural
ventilation system. This ‘MVHR’ system will extract heat from the kitchen and bathrooms
and recycle it into the home to reduce the demand on the space heating system.
• Solar heating in combination with an airto-water
heat pump produces thermal energy that is used for hot water and space heating.
• Natural ventilation, as well as internal and external
sun screening, ensures fresh air and a comfortable room temperature.
Triple-height atriums around the stairs allow natural ventilation through both
stack and cross ventilation.
In the summer the homes can be opened up and cooled through massive purge
ventilation.
• The control systems for the houses reduce energy
consumption and ensure
a healthy indoor climate

53. Day lighting
Perimeter and core day lighting is provided
through the use of light shelves in conjunction
with high building ceilings (95% of the floor area
has a 3 meter clear height).
This increases the penetration of natural light
while reducing glare. Consequently, the light shelves
help to reduce building solar heat gain, resulting in
lower building operating costs. A direct/indirect
lighting system is integrated with daylight from
light shelves and large areas of low-e glazing.

54. Glazing: The building skin is primarily double-glazed, clear low-e glass with five different elements
for each floor level, which include from top to bottom:
A clear panel to allow daylight penetration to the
light shelf.

63. 6 Steps to Choosing the Right Windows
1 - What kind of room is it - bedroom, Consider how much daylight and view
your customer wants.
Consider increasing the size of the windows or combining them together.
Remember the more daylight a room receives the larger it will feel.
We recommend at least a minimum 15% glazed area to floor space.
2- Select how the window opens
INTEGRA® electric Top-Hung
Centre Pivot
(Conclusion)

64. 3- Pine or white? Choose from natural pine or white polyurethane.
4- Consider the glazing options, glazing comes with a toughened outer pane.
Consider upgrading for additional safety and increased energy efficiency.
5- Install and insulate correctly for energy efficiency
• Select a suitable flashing for the right roof covering to match the size
and number of windows.
• Remember to insulat around the window to conserve energy and meet
Building Regulations.
• The easy to fit insulation collar provides the perfect insulation
interface between the window and roof structure.
6- Finish with a blind,
Choose from a wide range of blinds and
decorative shading from the sun.

65. conclusion
Using the nature lighting and ventilation in the buildings,
Conditioning with site plan ,topography, and choose the best orientation for the air
and solar radition
The glazing is 15 % to the net area floor (WWR)
The design strategy of the completed CarbonLight Homes
Model Home 2020 project, is that they conform to the principles of Active House,
addressing the dual challenges of energy design and liveability.
The original use of building technology and the exciting way it captures natural
daylight and ventilation to minimise energy consumption.
The properties were hailed as an exemplary benchmark for the design of future
sustainable homes.
It is possible to build bright and well ventilated zero carbon homes that the consumer
will want to live in and that the mass house builder can reproduce simply and
profitably.
