Inefficient power use in constructions is either more and more dear and unsustainable. certainly, the relief of the power intake of latest constructions is as least as very important because the layout of recent low-energy structures. Controlling strength use is something, however it is necessary to evaluate or estimate it, and to appreciate the variety of interventions for lowering its use and the tools for assessing the fee effectiveness of those measures.
This complete consultant in actual fact and concisely covers a few of the matters from a theoretical viewpoint and gives functional, labored examples the place applicable, in addition to examples of the way the calculations are conducted.
Topics coated include:
- where and the way power is utilized in buildings
- energy audits
- measuring and tracking power use
- techniques for decreasing power use in buildings
- legislative issues.
It presents a template for instigating the power administration technique inside a company, in addition to assistance on administration concerns similar to worker motivation, and offers sensible info on easy methods to hold it via. This ebook should still attract construction managers and amenities managers and likewise to scholars of power administration modules in FE and HE courses.

Techniques for reducing energy consumption Heating system 46 a guide to energy management in buildings In buildings with high ceilings, a warm-air system may turn out to be very inefficient, since the warm air will rise towards the roof. Destratification fans and ductwork can be fitted to direct the warm air back to ground level and reduce temperature gradients, improving efficiency. Often such spaces are better heated by high-level radiant heaters, which beam radiant heat directly to the occupants and surfaces.
Building management problems which can be solved easily and which will produce quick results include the following. Items left on overnight such as computers, photocopiers and printers Simple solutions may have far-reaching consequences – switching off our computers before we leave work can save 70 per cent of their energy consumption. Some energy-consuming appliances such as de-icers for external steps, ramps and car parks may be on without anyone knowing. Escalators which continue running when the building is closed will consume considerable amounts of energy over a year.
The energy audit report should include: 1. ). Hours used. 2. Description of heating/cooling/lighting systems, air-handling units, boilers, fittings, controls. 3. Thermal comfort – state whether conditions are acceptable. 4. Energy consumption – bills, estimates. If not available, state what you would need to do to find out – what measurements to make. 5. Comments on specific points about the operation of the buildings. Does everything work as it should, is it well maintained, and so on? 6. List of where you think energy is being wasted, where and how savings could be made.
