Introduction
Energy management has become an important part of business decisions not only the job of building managers or facilities managers or developer.
As economics of building ownership becomes a major risk consideration in building development energy management becomes very important has it constitute about 40% of the cost of building management
Everybody involved in building development, operations, management and ownership has to be involved in energy management.
“Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs”. Brundtland report’s definition of sustainable development:
Reductions in energy consumption – emissions and cost – by means of right-sizing of buildings and building services, and operating it in the most appropriate manner to meet user needs.
The impact of sustainable development and energy management on organisations CRS policies is also important
WHY MANAGE ENERGY?
The term energy management is defined as the process of controlling, monitoring and conserving energy. Energy management involves practices such as metering your energy and always taking any opportunity that presents itself to save energy.
Social impact
Economic Impact
Environmental Impact
Health Impact
Financial Impact
Most times we do not focus on real reason to create an efficient building that will conserve energy
Our objectives are mix but we all agree on all the above
WHY CONSERVE?
There is a social responsibility linked with environment impact of energy miss-use in buildings while there is a link between how we manage our buildings and the health of the users and ultimately the finance of the business
Studies have shown that employees who operate in an environment where there no concern for energy usage and management will not be able achieve productivity levels desired by the business
This ultimately affect the profitability of the company
An inefficiency managed building wastes between 15 – 18% of its operating cost of energy that should have been conserved
Carbon emission as a result of inefficient use of energy in buildings contribute to Global warming
START FROM THE BEGINNING – LCC, BEMs, BMS, BIM
Building Energy Management Systems (or BEMS) are computer-based systems that help to manage, control and monitor building technical services (HVAC, lighting etc.) and the energy consumption of devices used by the building. They provide the information and the tools that building managers need both to understand the energy usage of their buildings and to control and improve their buildings’ energy performance.
Your BEM system forms an integral part of your BMS system, the BMS Building Management System includes energy management, operations, maintenance management.

In designing, operating and managing buildings ‘fit for purpose’ it is imperative to apply the LCC modeling in design, selection of services and equipment, that will lead to an efficient building with the use of resources especially energy
LCC Whole life costing also known as life-cycle cost is used to describe the total outlay of ownership of an asset over its useful life. It includes the acquisition, set-up/installation, operating, managing, disposal costs.
ROLE OF FM IN ENERGY MANAGEMENT
In typical office building, energy use accounts for 30 – 40 percent of operating costs—the largest single category of controllable expenses. It is clear to see that many facilities could benefit from the use of green operations and maintenance strategies. Facility managers are in the position to be environmental stewards of the physical workplace— with the ability to upgrade a building’s equipment and day-to-day operations in order to be more energy and cost efficient.

BASIC ENERGY MANAGEMENT FOCUS AREA
HVAC – installing or retrofitting your building with an energy efficient HVAC system is critical – You may consider LG Multi-V system
Lift System – Modern lifts and escalators nowadays is design to minimize the use of energy as the starting torque is reduced, also lifts operating when called and stops at the last stop without wasting energy to go down as the next user may be on same floor or the nearest floor.
Day light harvesting – It’s important to incorporate day light harvesting into buildings to maximize opportunity of the day light, also building orientation is important in design and development to be able to achieve this
Light fittings and use of energy savings is also important there many LED light now that conserves more energy than normal energy saving bulbs consumes less than 5Watts.
Wastages can also lead to energy inefficiency if your building uses more water than necessary there is a cost to generating water
Alternative energy supply is imperative with solar, wind, bank of batteries (inverter); gas powered systems as strong possibilities for investment provided the ROI is in line with the company’s ROI
