When you know it’s going to be a hot day, close windows, curtains and external doors and close off internal spaces when not in use. Avoid cooking, washing and ironing until the house cools down in the evening. Plan ‘no cooking’ days or cook and eat outdoors. Consider eating out occasionally.

19 Stay warm in winter The secret to staying warm in winter is to generate only as much heat as you require for as little money as possible and then retain it where it is most needed. Your body is smaller than any room. By wearing the appropriate amount of clothing, you will fulfil the three points above at virtually no cost. Only heat the rooms you use on a regular basis. Choose the correct size of heater or air-conditioning system. Make sure you set the heating controls correctly, one degree lower than the recommended setting will save you money. Running a ceiling fan at low speed will help to circulate warm air. Insulate the roof space and walls in your new home. Fit effective curtains or blinds and open north facing curtains to let the sun in. Fit draught excluders to both external and internal doors.

Energy Audits Your 6-Star Guide to operating an energy-efficient home 20 Do It Yourself Gas Audit By understanding your own patterns of energy use you can help focus on where to save energy, save money and help the environment. Walk through each area of your home and record the details of each gas using item as below. You can typically find the ‘megajoules’ on the items nameplate or in the owner’s manual. If you cant find the megajoules search the Internet for that particular model. NB 1 megajoule MJ = 1,000,000 joules J. The rest is just an arithmetic exercise - multiply A x B x C x D to work out how much gas you use per year.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
