1 Low Carbon Schools Invest to Save Project Identification May 2012

2 Introduction Please take some time to fill out and return this questionnaire as it will help to identify potential energy saving opportunities within your school. In some cases, we may be able to implement some of these opportunities. The implementation of proven energy efficiency measures will reduce running costs for your school and also reduce its carbon footprint. The questionnaire is split into five sections, as follows: 1. General Information 2. Heating and Hot Water 3. Lighting 4. Building Fabric 5. ICT Each section contains a number of questions which can be answered simply and quickly. There are also some questions which ask for an approximate figure or for additional comments; these can be answered in the box provided. Please estimate answers from your knowledge and by walking around your school building(s): do not worry too much about being precisely accurate. In some instances, a photograph would help us get a better understanding of what equipment you already have installed. Please attach a digital photograph if you can. This is optional, but would be extremely helpful. On returning this form, you are welcome to forward any supplementary information (further comments you wish to make, condition information, previous surveys that may have been undertaken, manufacturers quotes) to assist our analysis. Please mark up the information with the question number it relates to. 2
