• Courtyard covering
- Cover the inner courtyard with
glazed roofs  reduce energy
use
- used often for historic buildings
 preserves historic character
- Huge energy savings
- Can save up to:
Case
Year round gas usage
through courtyard facing
facades
gas savings due to
courtyard covering

• Secondary Glazing
- Must be reversible in order to
protect the significance of the building
- Need a sufficient gap (at least 200
mm) between the two sheet of glass
- If not possible to have a sufficient
gap, one should consider double
glazing (see next slide)
- Some systems can be removed easily
in summer in order to take advantages
of passive solar gain
• Double glazing
- Usually too tick to fit into existing timber window
frame
- But now new products that are thinner but MORE
expensive
- Need a cost-efficient analysis
• Film inside the window
- Easy step
- Less efficient than secondary and double
glazing
- Different kind of films depending on the
orientation of the windows
- Use it when secondary and double glazing not
possible
GG90-92: Secondary / Double glazing / Film
Installation changes
• Solar panels
- Usually used for hot water
- BUT technically can be used for heating the
building  Need bigger roof area
- Can be installed on the extra building? in the big
parking of GG 90-62?
• Solar photovoltaic
- Cost much more than solar panels
- Produce about half as much energy as solar panels
- But this is electrical energy
- Can be installed on extra building? In the big
parking of GG 90-92?
Electricity decision tree
• Insulation improvements on the floor
-Improvement on the fabric of the building ->
demand of energy lowers
-Generally cost-effective
-Protecting air circulation & natural materials
• CHP units
-Cogeneration or combined heat and power
-Creating energy, by-product heat
-Energy & heat need to be levelled
-Units: efficient -> lower energy & carbon emissions
• Infrared light switches
- in areas that are not used frequently : bathrooms,
stairways, conference rooms and janitor
storage/closets.
- One specific type of passive infrared switches
(WSP250):
• a built-in sensor holds the lights off when natural light
levels are above the preset level
• Result (according to the producer of WSP250): 60%
energy savings
• Recycled paper for printers
- fixed paper provider of the UM: Océ Business
Services
- propose the paper provider the idea of a pilot
project:
• Introducing one printer in each faculty which uses
exclusively recycled paper
• If this pilot project is successful, the university could
start further negotiations about having all printers and
copy machines print on recycled paper.
• Water taps
– Faucet aerators: mix air into the water stream without
affecting the water pressure
– not expensive, easy to install, can use up to 50% less
water, does not sacrifice comfort
– 30 old taps in GG 90-92
• Green Roof
– partially or completely covered with vegetation or soil
 cut heating cost, reduce water run-off, increases
the roofs life span
– at additional building/ 72 “Oostgevel buitenberging” ?
Behavioural aspects
• Online questionnaire
– climate conditions at GG90-92
– energy consumption-related behaviour
– attitudes on saving energy
only 22 responses
• Behaviour change: difficult due to trade-offs in
time, cost, comfort
• Education programs
• Inform employees about changes
• Social marketing strategies
“Be bright, turn out
the light! WE Save
Energy”
– paper note, (informative) poster
• Feedback technologies
– real time feedback
– the Serious Game (Green My Place)
• Moving an organization towards sustainability
is an on-going process & takes time!
•
Mistakes that should be avoided
1. No sense of urgency
2. No Powerful Guiding coalition
3. Lacking a vision
4. Not communicating the vision
5. Not removing obstacles to the vision
6. Not creating short term wins
7. Declare victory too soon
8. Not anchoring changes in the corporate culture
Research project
sustainability
in FASoS
UM “Leading
in Learning”
research
project
• Look at influence of infrared heating system
on concentration/learning performance
• Mutual benefit
Legal aspects
• When do you need an environmental permit?
- Depend what kind of changes you want to do
(see website)
- NO for regular (low) maintenance and
renovations to non-monumental parts (since 1
January 2012)
• What is the procedure when you need an
environmental permit?
- You can apply online
- Extensive procedure = when you need to demolish
partially or completely something
- Regular procedure = Rest
• Costs
- Depends on the construction costs
- Construction costs = 50.000 or less  17 for each 500 but no less
than 131
- Construction costs = between 50.000 and 250.000  1.704 + 16,21
for each 500 above 50.000
- Construction costs = between 250.000 and 500.000  8.185 + 15,
50 for each 500 above 50.000
