Increased energy efficiency in industries, business, services and the reduction of negative environmental impacts go hand in hand. And the smartest solutions need not have negative impacts on comfort or profits. In energy efficiency consultancy, it is wise to consider the technical, institutional, financial and social aspects of improving energy production, transmission, distribution and use.

With so many businesses looking for ways to reduce their energy consumption because of cost, environmental concerns or the need to comply with regulations the opportunities to build businesses that deliver on those needs are large and growing. Analysts expect double-digit growth in this energy-efficiency market over the next few years, with more than 70% from commercial and industrial customers, and the rest from residential.

The buildings sector accounts for about 76% of electricity use and 40% of all primary energy use and associated greenhouse gas (GHG) emissions, making it essential to reduce energy consumption in buildings in order to meet national energy and environmental challenges and to reduce costs to building owners and tenants. Opportunities for improved efficiency are enormous. By 2030, building energy use could be cut more than 20% using technologies known to be cost effective today and by more than 35% if research goals are met. Much higher savings are technically possible.

Building efficiency must be considered as improving the performance of a complex system designed to provide occupants with a comfortable, safe, and attractive living and work environment. This requires superior architecture and engineering designs, quality construction practices, and intelligent operation of the structures. Increasingly, operations will include integration with sophisticated electric utility grids. The major areas of energy consumption in buildings are heating, ventilation, and air conditioning—35% of total building energy; lighting—11%; major appliances (water heating, refrigerators and freezers, dryers)—18% with the remaining 36% in miscellaneous areas including electronics. In each case there are opportunities both for improving the performance of system components (e.g., improving the efficiency of lighting devices) and improving the way they are controlled as a part of integrated building systems (e.g., sensors that adjust light levels to occupancy and daylight).

Saving energy in your business can significantly reduce your operating costs and your impact on the environment. Understanding your energy use and taking steps to become more energy efficient can benefit your business in a range of ways. Saving energy will help your business cut carbon emissions, reduce costs and enhance your image.

Energy efficiency and conservation should be a part of your business planning. There are many low-cost steps that businesses can take to start saving energy now, as well as more detailed actions that can happen over time.
