Technical changes

Draught preventing screen -To counteract the high door -Reduces draught at reception - Can save up to: Case Year round gas usage due to draught gas savings due to draught block CO2 emissions avoided in one year CO2 emissions avoided in 15 years Cost savings every year Cost savings in 15 years Best case115,12m 3 46m 3 81,88kg1,2ton€24,13€361,94 Worst case230,24m 3 92m 3 163,76kg2,4ton€48,20€723,12

Glass covering in patio’s - To reduce convection losses - Can save around: Case Year round gas usage due to convection through facade gas savings due to patio covering CO2 emissions avoided in one year CO2 emissions avoided in 15 years Cost savings every year Cost savings in 15 years 50% reduction2110m m ton€552,8€8292

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 CO2 emissions avoided in one year CO2 emissions avoided in 20 years Cost savings every year Cost savings in 20 years 50% reduction15134m m kg413,9 tons€6092€

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 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 – 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! “Be bright, turn out the light! WE Save Energy”

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

Look at influence of infrared heating system on concentration/learning performance Mutual benefit sustainability in FASoS UM “Leading in Learning” research project

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 = or less  17 for each 500 but no less than Construction costs = between and  ,21 for each 500 above Construction costs = between and  , 50 for each 500 above Ect… (See website)
