Skip to 0 minutes and 11 secondsOh, hello there. Hi Thom. So, what have got here then? We've got one of the four bedrooms in the house. I just thought I'd draw your attention to some of the good initiatives they've got here. This is secondary glazing. OK. Obviously you've heard of double glazing a window, but this is designed to keep the heat in without affecting the original windows, when which are quite pretty in this house. And is that a lot cheaper than double glazing? It certainly is. Obviously you just put a pane of glass on the inside. There's no need to change any of the outside features of the house.

Skip to 0 minutes and 42 secondsAnd it will reduce energy loss through windows, which is a major factor in a house such as this. Fantastic. What other features have we got in this bedroom? Around the window we've got blinds to keep more heat in. And we've got the curtains. Unfortunately, the curtains do cover the radiators. So the radiators are old. And they don't have any thermostatic controls. So you just have all on or all off. Nowhere in the middle to control the temperature of the room. Great. And is there anything we can do to improve that in a house like this? In a house like this they've done the right thing to not put anything up against the radiator to block any of the heat.

Skip to 1 minute and 16 secondsAnd so it will be using its maximum potential to heat the room. OK, and that's as good as we can go? It is in a house like this. Great. Also, I'd just like to draw your attention to the light bulb. They are original, old-fashioned light bulbs. And we would recommend they change them to energy-saving light bulbs to reduce energy consumption in the house. That makes sense. It does make sense, especially smaller things like this can make a big impact. Yes, right, light bulbs in here. And then secondary glazing could really help with their heat loss. It certainly is. It certainly can. This is the only one in the house, which is unfortunate.

Skip to 1 minute and 48 secondsBut it shows it can be done throughout the house. And they're making progress. They are. Thanks for taking us around. No worries. Well, I hope you guys enjoyed looking around. Enjoy the rest of this session. See you again soon. Bye.

Keeping the heat in Cripps House

Postgraduate researcher Thom talks to Nottingham’s Environment Officer, Helen Rutherford, about energy usage in Cripps House. Helen explains to Thom how we can judge the energy efficiency of our domestic fittings and appliances.
