There are many different cost effective measures which would cause the businesses fuel bills to drop and in doing so the building would benefit highly from an upgrade. Below I have shown my recommendations on what cost effective measures which you can take and in doing so will upgrade the building.

A client is concerned that their fuel bills are high. They have asked your company to prepare a report on how to upgrade their building to reduce their fuel bills. The building was constructed in 1950 and is used as an administration centre. It is in an industrial estate and is not a listed building.

The building is a one story construction compromising of:-

• Composite stone wall 350mm thick. Floor to ceiling = 3m
• Single glazed timber windows in good condition.
• Timber & glass double swing doors leading into entrance hall
• A pitched, slated roof which is showing signs of ‘nail sicknesses. One pitch is south facing.
• Uninsulated roof void which contains a large volume of pigeon waste and feathers.
• Painted concrete floor in good condition.
• The electrical system was installed in 1960 using PVC cables with one power point per room.
• Fluorescent tubes provide all lighting.
• Gravity fed hot water system comprising of 28mm copper distribution pipes with a 22mm secondary return. The insulation on the hot water cylinder appears to be cement based and poor condition.
• Cold water and indirect system with 28mm copper pipes and a galvanized steel storage system ( showing signs of " pinholing")
• Solid fuel central heating system(installed 1950), with gravity fed 28mm low carbon steel flow and return pipes running along the inside of the outside wall. There are column radiators in each room that are controlled by wheel head valves.

Cost Effective Measures
Roof Void
One cost effective measure which would help the actual building itself a great deal was if the uninsulated roof void which the building has was firstly removed of the excess pigeon waste and of the pigeon feathers. After removing this waste, this roof void should be filled by using a cheap and effective way by using a material such as glass mineral wool. This material can fit in between any irregularly placed rafters and would prevent a lot of heat from escaping the building and keep it within the building itself. The benefits to the building are great as the building now will require less energy output from the heaters as more heat is trapped and prevented from escaping.

Rewiring of Electricity
Another cost effective measure which would reduce the high fuel bills which I recommend is that the business gets their electricity re-wired and more up-to-date. As they are using old 1960's wiring they will be using a lot more voltage than back in the 1960's and for a lot more appliances as well. By increasing the number of sockets to 2 to a room there is not an overload of electricity to the sockets. This will benefit the building as environmental and the health standards agency cannot place any possible fines on the business as they have a safe working environment and there is no danger of an employee being hurt from an overloaded socket.

New hot water cylinder
A third cost effective measure I would advise would be that the hot water cylinder is changed as the insulation on this piece of equipment is in poor condition. By upgrading this system then there will be lower hot water fuel bills as the tank will not have to heat the water up as much and the tanks water will be heated up and will not go cold easy. The benefits to upgrading this to the building are that if the business decides to sell the building they would get more money because the building has an upgraded and good condition hot water system.

Changing of cold water pipes
Another cost effective measure would be that if the business changed their cold water pipes as this would reduce the amount of money spent on cold water. These pipes have "pinholing" in them and by changing the pipes this will help less water being lost through these pinholes and as a result the building will benefit from a new water system being fitted as employees can receive more water.

Benefits of Upgrade

In conclusion I would say that if the business changes their hot water cylinder and insulation, cold water pipes, electricity sockets, and clear the waste and insulate the roof void, then the business will see a fall in the prices which they are paying in their fuel bills.
