hi there!

We are from ‘Radical Studios.’ We’re glad that you have chosen to live in a passive solar designed home. Feel free to write any notes and questions in this book and take it along with you for our meetings. Talk soon!


letter from the author

09/11/2016

dear reader, As a fellow human being on this planet, I searched for meaning, fulfilment and authenticity. How does this relate to buildings? I believe that building is a necessity to life as bread is to us. Therefore, I take my job seriously. I hope we can help you transition to live better, be healthier and with more purpose. I came across passive solar design after learning about sustainability back at university. It was that day onwards that I wanted to share why I think that passive solar design is ever so important in this age than ever before. I’m curious to know what you think about sustainability and about how you first heard about passive solar design? Good news. Passive solar design can help make our electricity/gas bills cheaper. It can even help you to open your eyes and see a new light to sustainability. Plys, it can help form new bonds and relationships with those around you. Inside this book are the ABC’s of passive solar design. As simple as that. I hope you and your family read this together around the dinner table and discuss these things. Happy reading & learning, Violet Director of Radical Studios

the truth about sustainability

1

‘Sustainability’ in general You are right when you say that ‘sustainability’ is about taking care of our natural environment. Actually, it includes all the aspects on the left. But guess what? Sustainability goes even deeper...

“... reducing, re-using and recycling...”

“the light green packaging on our products...”

I wonder how the term ‘sustainable/sustainability’ came about... It could be assumed that some people have realised that we have not been ‘justly’ when using our natural resources to the ‘good’ for our society. Just like everything we touch, it’s temporary, it fades or breaks, or ends... Are we at our peak? Ask yourself realistically, what will it be like in 50 years? Is it a nice or bad-looking vision? I don’t want to paint you a grim picture but we believe that sustainability is in the heart of everything, not just architecture but morally/ethically/socially/economicaly/environmentally...

“eco-friendly materials...”

‘Sustainable’ home Homes waste considerable amount of resources and emit carbon emissions (manufacturing materials, transport etc. there’s a lot that you don’t know about!) “protecting the environment for the future...”

People are awakening to the fact about buiding ‘sensibly’ and being ‘sensitive’ to the environment. That’s a good start. Some things are: - safe/recycled materials - managing rainwater/greywater/stormwater - minimising energy consumption (energy efficient lights + appliances) - holistic landscaping (permaculture!)


our manifesto radical

- relying more on ‘natural’ resources/strategies instead of advanced technology - challenging the ‘material/ consumerist society by thinking of more ethical, healthier solutions for us as a society

sustainability

intangible

- relying on something we can’t physically touch i.e ‘natural’ environment (sun, winds) - renewable sources of energy

- ‘small is beautiful’ - small self-sufficient units of social/ community development/ growth i.e sustainability! - local communities, local people, local resources, local businesses!

flourish


what’s the difference between... passivhaus

passive solar design

- Design of a more ‘rigid’ building fabric i.e airtight (well sealed) - ‘Controlled air temperature’ using an ‘air ventilation unit’ (not passive) - complex mathematics & building science to precisely calculate efficiency performance

- uses basic ‘rules of thumb’ principles; orientation, insulation, glazing, thermal mass etc - less of a vigorous criteria compared to ‘Passivhaus’ international building standard

energy efficiency

- may require ‘mechanical/artifical’ HVAC systems (i.e not ‘passive’ in nature eg. Passivhaus) - focus more on specialised ‘items’ such as solar panels, renewable technology rather than the designing the building fabric to work with the microclimate as possible


building code of australia

in 2011, BCA announced that all houses need to meet a minimum of 6 star energy rating a minimum standard (standards are just the starting point!) not mandatory (but it’s still good to follow it!)

BCA Section J (Energy Efficiency) rating tools: - NatHERS (assess thermal performance of residential houses) - AccuRate (modelling of air movement & zoning patterns)

bca

what is it? It’s a national code that applies to all states in Australia

- building fabric - glazing - building sealing - heating & cooling systems - artficial lighting

BCA defines 8 climate zones for thermal design in Australia. We are in Zone 6!


orientation

2

your notes:

Sites with a large ‘width’ are extended on the West and East axis (living areas would best be in the upper section).

Sites with a narrow ‘width’ have a long body on the North and South axis (living areas would be in the upper north section).

reference notes/extra study - McGee C 2013, Orientation, yourhome - Port Phillip 2012, Energy Efficiency, SDAPP

Taking advantage of orientation in the begnning of the design can help you achieve up to 1 Star of your rating. Yay!

- when buying a new house or land, take notice of the sun path(where the sun rises and sets). Remember, the point of passive solar design (especially in Melbourne) is to get as much sun in winter (sizing & location of windows, shading - see passive heating page).

- Energy Authority Victoria 2006, Ch.4 - Siting & Solar Access, ESHM


Orientation: - stems from the 19th century word ‘orient’ which means to ‘position’ or direct something towards. Facing the northern rooms i.e living towards north(sun) is the essence of passive solar.


passive solar heating

your notes:

N

Let’s imagine if we have a ‘lot’ with a narrow width. Zoning such spaces would include grouping northern spaces (living/dining areas) and southern spaces (bedroom + utilities)

N

To gain winter sunlight to warm up the day areas, windows are placed on the northern facade, E & W windows are to be smaller with adjustable shading (lower angle sun) and southern windows tend not to be included as no sun is exposured here...

reference notes/extra study - Reardon C 2013, Passive solar heating, yourhome - Energy Authority Victoria 2006, Ch.6 - Thermal Mass, ESHM - NCC 2015, J5.2d(Space heating), BCA

zoning: - your design should allow light to penetrate easily & air to circulate easily. Also having doors in open spaces minimises air wastage when heating (thermal mass)

window: - all glazing requires ‘seals’ to prevent ‘draughts’ in winter (can account to 25% of heat losses).


Thermal mass: - The ability of a material to store heat energy. - In winter, thermal mass absorbs ‘day’ heat and stores it for release at night.

1. Sunlight is admitted through a glass aperture (window) 2. The sun’s rays hits the surface of the material (absorber) 3. The thermal mass material under the ‘absorber’ has the ability to store sun’s heat. 4. At night/when temperatures fluctuate, the stored heat is distributed or ‘re-radiated’ out around the room.


passive cooling your notes:

passive solar design is also about ‘blocking’ the sun i.e in summer. A simple eave (horizontal projection) will block the 76° afternoon sun to keep your living areas cool!

Similar to water, wind needs a unobstructed pathway to pass through. To maximise a cooling effect, windows need to be placed directly parallel to each other with no obstructions.

reference notes/extra study - Reardon C 2013, Passive cooling, yourhome - Energy Authority Victoria 2006, Ch.8- Air movement, ESHM - NCC 2015, J2.4(Glazing & Shading), BCA

shading: if installing a solar ‘pergola,’ ensure the chosen plant sheds its leaves in winter to allow the sun for thermal mass.

cross ventilation: by placing windows on opposite sides of the room, hot air is pushed out and replaced by cool air


Stack effect (conductive): - Air movement is driven by the rising of warm air. - By creating a thermal ‘stick,’ hot air escapes out of the high vents and draws cooler air at lower levels

Night purging: - Open windows in the evening - Concrete floor releases stored heat.. - Aided by cool winds through windows - Stale/hot air rises up... - Exits out of the high louvre windows & replaced by clean, cool air through ground level windows.

goodbye from the author

09/11/2016

dear reader, I hope this companion book was helpful and easy for you to understand. What did you learn? Tell us at our next meeting! If you are still a bit confused about passive solar design, I hope you can at least take this away:

?

passive solar house

What do you think is missing out in the equation... Well, the whole point of a passive solar house is for YOU to enjoy life, adapt to the temperatures in your environment i.e thermal comfort! Therefore if the building is designed with the passive solar elements already... YOU just need to make it happen. It’s an ongoing effort and interaction with the building. Test out how your newly built passive solar house is when your move in. We’ll contact you to see how you go. It’s okay, it should feel a bit new, but that’s the thing - living in a house should be about being aware of the climate and ‘understanding’ how the passive solar house works (we’ll help you with that). Talk soon :)

Take care,

r

Violet Director of Radical Studios


some handy tips...

Curtains with pelmets can also stop about 25% of heat loss from a window (see material specs page)

4

retrofit thermal mass by: - placing bricks/concrete along the wall - put large sealed containers of water in your room - move books/bookshelves into your living room (books are heavy

ceiling insulation reduces the power needed for heating to 100W per square metre

Smaller spaces heat more quickly than larger spaces. Keeping door closed and areas separated increase the efficiency of heating and you don’t pay to heat areas you are not using.

cross ventilation: by placing windows on opposite sides of the room, hot air is pushed out and replaced by cool air

Have an airlock between your front door and the rest of the house. You can stop all that precious heat from escaping the house, and not worry about the front door being open. (See an example on the material specs page)


Using plants for shading – deciduous plants allow winter sun through and exclude summer sun

Ventilation is essential to exhaust unwanted odours, water vapour and pollution, and replace them with fresh air. Use exhaust fans in wet areas and when cooking. Open windows and doors where possible to help remove indoor pollutants.

To prevent unwanted ventilation (draughts), wrap up the internal skin of the external walls of the house with reflective foil and lap and tape up around all windows and doors, ensuring that there are no tears or holes in the wrap

landscape can be designed to control the flow of breezes or block unwanted sun

Home energy ratings aren’t everything - behaviour and resource - use also also considered

If buying a new car look for the fuel consumption label that will tell you how economical the car is. Consider a hybrid petrol/ electric car to further reduce your greenhouse gas emissions.


structural insulated panel system (SIPS)

We recommend SIPS ...

History... The idea of having two panels squeezing a central insulated core began in the 1930s in the US. Frank Lloyd Wright was an advocate for such material system. The essence is its insulative performance.

SWOT analysis

S Strengths

SIPS is used for your structural exterior walls, interior walls and roof. It’s incredibly lightweight, easily flatpacked and carried to your site and worked on quicker than conventional timber framing systems AND airtight (no more draughts!)

The supplier - Ozone Panel

- ‘pre-made’ elements made in factory means faster building times on site - Requires less ‘energy’ to make (less raw materials)

‘Ozone Panel’ system

W Weaknesses

- still relatively new to building industry - lack of ‘local’ material avaiability

- new collaborative approach O to managing construction process Opportunities - combination of other systems/materials

T Threats

- distribution and supply - not mainstream materials + techniques

‘Ozone Panel’ company advocates with our sustainablity manifesto. They opt for something radical (passive techniques), efficient (thermal performance) & good for you, the family and the environment!

- Two facings/facades of OSB(type of timber) bonded to Polystyrene foam (insulation core)

http://ozonepanel.com/panel/ wholeofhouse.bunnings. com.au/pdf/SIPS_product_


Magnesium Oxide Board

We recommend MgO board ...

(MgO)

History...

for your internal wall linings and ceilings. MgO boards are a non-toxic and fully recyclable alternative to gypsum & fibre cement materials. Like SIPS, it’s strong, easy to cut (easy to transport) and allows for swift construction!

Magnesium based cements are some of the olderst building materials! It was used as mortar by the Romans and used for the Great Wall of China.

SWOT analysis

S Strengths

W Weaknesses

- attachments is done by a nail gum (faster construction!) - Requires less maintenance over its lifespan(durable)

- using magnesium in other construction materials to make it ‘biodegradable’ and Opportunities with more ‘recycled content’

Threats

‘MgO’ board Horizontal sheeting board (made up of magnesium oxide + magnesium chloride)

- still relatively new to building industry - more expensive than gypsum drywall (plasterboard)

O

T

The supplier -MgO Corporation Aus.

- distribution and supply - media news of reported risk of mould and ‘concrete cancer’ from MgO Boards’ chloride salt content.

MgO Corporation Ltd aims to be more ‘sustainable’ in beginning (manufacturing process) & at its future lifecycle (recycle + re-use). MgO Corporation has also gone the extra mile to independently test & certify their products ! http://magobp.com/ environment-sustainability/

‘passive’ design, ‘active’ relationship

key words: thermal comfort behaviour + routine maintain + engage adaptive model

reflection qns: Lifestyle factors: Are you familar with: - turning on/off ceiling fans? (summer/winter settings) - energy monitoring system Do you prefer: - manual operated louvres OR automated louvres (windows) - central control system or a remote control

- is there a time you can’t open window at night/ during morning?) - Who is at home the most? - Is there someone in the family who is sensitive to temperatures or unwilling to ‘manually’ operate windows etc.? - Are there other external factors to consider? i.e privacy, noise (when open window) Are you willing to... - get up early to close windows in the morning after opening up overnight? - prefer central control system on wall or remote control ?

An example of a ‘how-to use it...’ occupancy training

External venetian blinds

Internal venetian blinds

a Pressing the button (Up/ Down) or turning the control knob (LEFT/RIGHT) for blind to move in chosen direction. The blind can also be stopped at any position. Tilting behaviour: press the button or toggle switch in the desired direction. The slat angle is changed.

b Slow down the rotation of the crank before the slats are completely retracted. The same rule applies when opening the blinds. To tilt slats: Turn the crank in the required direction. The slats will open when retracting and close when deploying.

switch

crank

Louvre windows (east & west) c Press the OPEN on the remote control. To partially OPEN it, hold the button & release it. Same applies for the CLOSED operation. At any time when the louvre window is opening or closing, press the middle TOGGLE button to stop the window.

remote control

Training sessions: - house tour (explanation of how to work the passive solar elements) - In groups (role-play)

post occupancy evaluation - after you have moved in after a week or two, we will meet again to see how you are settling in. We will ask how your daily lifestyle is fitting with the routine behaviour in using your passive solar house.

mini dictionary A

B

active systems - ‘mechanical’/HVAC systems as opposed to ‘passive’

Building Code of Aus (BCA) - national building code based on behalf of Aus. government

air quality - amount of gases, vapours, pollens in the air - ‘maintaining’ it to promote a ‘healthier’ work environment

building envelope - the ‘skin’ that separates the interior and exterior i.e walls, doors, windows

E

F

embodied energy - energy expended to produce, transport, maintain a product

Fenestration - design & construction of windows & doors

energy efficient - minimise use of energy imported from gas/electricity companies to maintain occupant comfort

Forest Stewardship Council - non-profit organisation that sets standards for companies to responsibly manage the world’s forests.

I indoor air quality (IAQ) - measurement of the overall ‘cleanliness’ of the air insulation - material that retards the flow of heat (prevent draughts and the summer heat!)

L

C

D

climate change - human activity that impacts the global atmosphere & has effect on long term weather.

direct gain - ‘passive’ energy gain opposed to ‘indirect’ gain methods (trombe walls)

cross ventilation - use of wind & pressure differences to ventilate naturally.

diurnal - occuring in a 24 hour period; daily

G green roof - ‘living’ fauna and flora that assists in air quality, thermal & acoustic insulation & stormwater retention greenhouse gases - density of carbon dioxide containing gases that get trapped in the atmosphere

M

H heat sink - an element capable of absorbing heat eg. concrete floor house energy rating - 6 star energy rating assessment (BCA) required for any build

N

Light-Emitting Diode (LED) - a technology that produces light by causing electrons to flow through lamp

micro-climate - climate in a confined small area with differences wind patterns etc

night purging - flushing out at night (naturally cool from built up heat from day gain)

Low E - glass that has metal-oxide coatins that blocks heat from sunlight

mixed mode - natural ventilation combined with mechanical HVAC systems

non-renewable - a natural resource finite in suppl y because of its scarcity, rapid depletion over time


mini dictionary P passive solar design - an ‘integrated’ building design approach that optimises building’s form, fabric & orientation to reduce energy usage & promote occupant comfort.

S stack effect ventilation - chimney like space that extract warm air and allows cool fresh air through at lower level sustainability - a very difficult word to define... it keeps changing...

V VOCs - chemicals that contain toxic/ azardous chemicals (paints, adhesives, carps, particle board) which effect our human health

P permaculture - self reliant people to maintain agricultural productive ecosystems - food, energy + shelter prefabricated - manufactured prior to delivery & on-site assembly

T Thermal comfort - perceived comfort based on metabolism, clothing, room temperature. Thermal mass - material that can store heat (concrete, masonry, water walls, brick, rammed earth)

W Whole-of-life cost - analysis and planning (design and management, feasibility) & environmental & economic costs considered

R

S

R-value - measure of the ‘insulating’ ability of the material/element

solar heat gain coefficient - measures how well a product blocks heat from sun

reverse brick veneer - exposes thermal mas to interior to make most of heat storage (passive)

SIP - panels made from a thick layer of foam sandwiched between two layers of OSB.

U U- value - measures the rate of non solar heat loss or gain (lower the value, the greater the window’s insulating value) i.e how well a product prevents heat from escaping!

V vapour barrier - ‘moisture’ barrier, doesn’t allow water thorugh! ventilation - intentional air flow!

Z Zoned heating - control of conditionings like temperature in a ‘portion’/ zone of a building i.e manually (thermal mass)
