Are Buildings Evil? - an evening with Professor David Coley

ARE BUILDINGS EVIL?

OR 16 WAYS CAN WE GET MORE PASSIVHAUS

1. OPENING EYES

2. USING THE CONCEPT OF EVIL

Evil

Immorality. Usually perceived as the dualistic opposite of good. Commonly associated with: conscious and deliberate wrongdoing, discrimination designed to harm others, destructiveness. (Wikipedia)

8. NUMBERS

We need a new way of thinking, a new language to relate the form of such buildings to the harm they are starting to do to those around the world less fortunate than ourselves.

HOW MANY MILES PER GALLON DO YOU GET FROM YOUR HOUSE?

Annual energy use (kWh)= --------------------------------- Internal area of house

SO WHAT DOES WORK: SOME PHYSICS

1. Why do we have heating systems and why do we heat buildings?

2. Why do we cool buildings?

3. Why do we light buildings during the day?

http://cambridgevending.co.uk/?page_id=974http://www.welcomemobility.co.uk/

Person = 100 W = 100 humming birds

3 people + lights + PC + fridge + TV + sunlight = 960 W = 960 humming birds

= 1040 W = 1040 humming birds

So the energy gap in a super-insulated house is around 80 W or 80 humming birds, or 3 candles

LOSS

9. COSTS

http://www.conkerconservation.co.uk

6% increase in cost of building, therefore 3% of house price, or £6,000.

Why do we continue to pay a winter fuel allowance instead?

CEPHEUS – Cost Efficient Passive Houses as a European Standard- 113 Passivhaus units in 14 developments around Europe

Result with the perfect family in every house

From: Ramallo González, Alfonso P., Blight, T. S., Coley, D. A. (2012) (In Press) Robust low energy design that accounts for occupant behaviour.

_RAMALLO

But with lots of different families

From: Ramallo González, Alfonso P., Blight, T. S., Coley, D. A. (2012) (In Press) Robust low energy design that accounts for occupant behaviour.

Note: the super low energy designs have evaporated and the number of options is much reduced

12. APPEALING TO THE PAST: FRAM

First Passivhaus?

The sides of the ship were lined with:tarred feltcork paddingdeal panellingthick layer of feltair-tight linoleuminner panelling

= about 15 inches.

Saloon comfortable with no heating with external temperatures in the range -/+22°C

13. EDUCATION

50 PhDs over the next few years

14. BUILDING ONE IN A PUBLIC SPACE BY ASKING PEOPLE WHAT THEY WANT

SO, WHAT DOES THIS SUGGEST?Super insulated.

Size of windows under control and triple glazed.

Can be light or heavy weight.

Energy will be very low, whoever uses the building and however they use it (almost). Hence promise the client that it will use very little energy.

If we remove the need for much heating we can replace the normal heating system with something very small.

This removes the need for much in the way of controls.

If occupants leave the door open a lot they will get cold.

If the heating system is very small then we could use electric heating.

Electric heating has the highest running cost – GOOD.

Electrical heating goes well with mechanical ventilation.

Mechanical ventilation goes well with heat recovery.

So we have an all electric building.

This implies PV.

This implies a north facing building, which is ideal for a school.

And yes, it does work.
