Sustainability

The School of Languages, Linguistics and Film strives to embed efficient processes which minimise its impact as much as possible on natural resources, the economy and our community (both internally and externally) - as part of a wider active Sustainability Committee and Student Society, and QMUL Sustainability, who are working hard to drive the sustainability message across the University through the implementation of the University Environmental Policy, Sustainability Action Plan and Carbon Management Implementation Plan.

Bancroft Building Energy Audit

Date of energy audit:

2/06/2015

Department/Building/Area covered:

Francis Bancroft- 1st Floor SLLF rooms

Persons conducting audit:

Jess Hawes and Has Yate 

Normal occupancy hours of building:

8am-7pm

Cleaning times:

Early morning; approx. 6am

2. Lighting

Are any tungsten lights present? Can they be replaced with compact fluorescents (energy saving bulbs)? Look particularly in store rooms, uplighters, desk lamps etc.

Yes- T5s and T8s present throughout the department.

If there are several light switches, can they be labeled to make it more obvious which switches relate to which appliances?

All light switches labelled.

Can lights be switched off to make use of daylight? (e.g. lights parallel to windows or in corridors)

Corridors don’t have windows so lights cannot be switched off. This is true in a number of resource and printing rooms too. However, the lights are on sensors in these areas. Offices make use of daylight, although light levels are low.

If space is intermittently occupied (e.g. store rooms, toilets, kitchen areas, copying rooms, corridors) is there scope for automatic lighting controls?

All installed.

Are any external lights on during daylight hours?

No.

Can main lighting ever be switched off and use made of desk lamps?

Not possible in computer rooms. Lights in main offices are generally zoned, but desk lamps could be provided if deemed necessary.

Do any light fittings need cleaning?

No- all clean.

Do windows and skylights need cleaning to allow in more natural light?

Yes. JH noted- this should be scheduled centrally as PAR bid was funded.

3. Heating

What is the actual temperature in the space?

Generally 21 degrees as indicated by Green Impact wall thermometers. Warmer in some rooms.

Does the temperature vary much during the day?

Yes- gets stuffy.

Do occupants complain it is too hot or too cold?

Yes- staff mentioned that it was commonly hot and stuffy at the moment. Heaters are available centrally indicating that it gets cold in winter months.

If there are Thermostatic Radiator Valves (TRVs), are they set correctly? Do they actually work or are they broken?

No TRVs- there’s a building ventilation system which provides heat. Vents on this can be opened or closed, but there is no precise control over heat output. This is controlled by the Building Management System.

Are radiators effective and giving consistent heat? They may need bleeding of air or maintenance to remove dust and sediment.

Yes.

If there is a room thermostat, is it correctly set?

Not generally present. Where present this varied- 16 degrees in one room, 21 degrees in another.

If the room tends to overheat, is there any bare pipework that could be insulated?

Pipework is boxed in.

Are radiators blocked by boxes and furniture restricting air circulation?

Yes, although this is due to space restrictions.

Are portable electric heaters in use? If so, why is the heating system not adequate?

Yes. Staff sometimes get cold in winter. Heaters are centrally bookable.

If there are permanent electric heaters with individual temperature and time control, are they set correctly?

No individual temperature control.

Are external doors and windows closed when heating is on?

Yes- in some rooms windows are open, air conditioning is on, and heating is also on.

Are any window panes cracked or broken?

No.

Is there evidence of problems with double glazing (e.g. moisture between panes).

No.

Is there adequate draught proofing on windows and external doors?

Yes.

If there is a roof space, is it insulated?

No roof space.

Are blinds closed at the end of the day during winter to cut down on heat loss?

No. This may benefit insulation, although many blinds were missing / broken.

Is heating or air conditioning on in unused spaces, such as cupboards, corridors?

Ventilation system is on throughout building and cannot always be controlled. Some unused rooms need cooling because of electronic equipment, e.g. printers.

4. Cooling and Ventilation

If there is air conditioning with local controls, make sure it is only on when necessary. Is it obvious how to control it? What temperature is it set to?

Not always obvious how to control (e.g. is display showing temperature of the room, or the air conditioning). Could benefit from having posters designed and put up.

Is air conditioning running at the same time as heating?

Yes, widely.

Could the building reduce heat by closing blinds or fitting reflective film to windows which reduce solar gain? Remember, unnecessary lights and electrical equipment also produce heat.

Reflective film would reduce the minimal daylight available.

Are all external doors and windows closed when air conditioning is on?

No external doors. External windows open in almost all rooms.

Are you making the most of natural ventilation? Opening windows overnight in the summer, where it doesn’t present a security risk, will help cool the building down and reduce the need for air conditioning.

No. Although this is a first floor department, so this may pose a security issue.

Is heating or air conditioning on in unused spaces, such as cupboards, corridors?

Yes where there is electrical equipment.

5. Electrical Equipment

Are computers, printers, photocopiers and other equipment switched off at the end of the day?

Yes- computers and printers are on automatic shutdown.

Can screens and other equipment be switched off during the day?

Computers are new Dell machines- the screen and computer are all 1 unit.

Can computers be programmed to ‘power down’ mode?

Yes- they are already programmed.

Can standby settings be avoided? (e.g. TVs, LCD projectors, printers etc.)

Generally no if centrally controlled. For other items, reprogramming would be required.

Are photocopiers, fax machines and other equipment on ‘Energy Saver’ mode during the day?

Yes

Are photocopiers in a well ventilated area – not where there is air conditioning?

Generally yes, although a few are located in rooms without windows due to space restrictions.

Can a 7 day timer be put on some equipment? (e.g. photocopiers, water coolers, cold drinks machines). These cost less than £10 and can be purchased online or from electrical and homeware shops.

Yes- potential idea to be implemented, rolling out in kitchen first.

Can any equipment be switched on later and switched off earlier?

Would need reviewing in next academic year.

Could timers be fitted to water coolers?

No

Are kettles overfilled for hot drinks?

Yes- there was evidence of excess water in the kettle during the audit. Fixing the hot water boiler may influence this.

Can kettles be removed if there is a wall mounted boiler?

Potentially not- kettles used for boiling greater volumes of water. Current hot water boiler is not working.

Are fridges places next to heat sources? They run more efficiently when in a cool environment.

No.

Is the office fridge/freezer defrosted regularly?

N/A

Is the fridge thermostat working and set to the right temperature (2-4 °C)?

Yes

Are microwaves switched off at the plug after use?

No- potential location for timer.

Is equipment clearly labeled so that staff know how to activate energy saving features or switch it off?

No- could be implemented.

6. Water Use

Is there any evidence of water leaks? (e.g. wet pathways on a dry day)

None at present, have been in the past.

Are taps left running? Are there any dripping taps? Do taps need maintenance?

Generally no.

Is there scope for push button taps?

Installed in bathrooms.

Are hot water heater timers set correctly?

Currently centrally controlled.

If there is no timer should one be fitted?

Currently centrally controlled.

Is water escaping from overflows either inside or outside buildings?

No evidence of this externally.

7. Awareness

Are there posters/stickers/guidance displayed to remind people of good practice?

Yes- there are some areas where this could be updated e.g. for air conditioning.

Would it be of benefit to have a formal energy audit with a member of the estates team?

Audits were carried out in Autumn 2014 using consultants. Results can be requested from the Estates and Facilities Sustainability team.
