AEC are controls specialists; our focus is on identifying and delivering energy savings on buildings’ heating, ventilating and cooling systems. As these systems represent the single greatest energy consumer in most buildings this is probably the single most significant opportunity to save money and reduce CO2 emissions. We work in many types of buildings and on all types of control systems and have an established track record of savings within the range of 20% - 50% of HVAC energy.
Our vision is straight forward;
“To maximise the efficiency of building control systems through better understanding of the heating flow dynamics and in so doing being able to redefine best practice and reduce long term energy consumption.”
In other words we are able to answer the simple question “How energy efficient is your building?” And help rectify the huge energy efficiency deficit created through poor control strategies without compromising the systems ability to deliver the required building services.
The opportunity is best summed up in the opening sentence of the CIBSE / BRE General Information Report 40 “Heating Systems and their Control” which states:
“It is estimated that 90% of H&V controls in buildings are inadequate….”
We have developed a unique method to audit heat demand, match control performance to it and implement enhanced control specifications to maximise a building’s energy efficiency. We can literally measure the demand for energy (heating & cooling) from a building as well as the amount of energy being supplied, the difference being the opportunity to save. The savings are then delivered through an enhanced control strategy implemented on the incumbent building energy management system. This process is totally transparent, one where possible we involve our clients and their existing building management people as part of the process of delivery, this we hope will give them ownership of solution.
We work with leading property owners and managers across a wide range of building types from the Tower of London to local authority community hearting systems, and have achieved savings typically of over 20% and in some cases up to and over 50%, without any loss of amenity or service standards to their buildings.
Our work in this field was recognised by the award of a grant under the “Future practice” of the BRE, Best Practice scheme. Dr Roger Hitchin of the BRE had this to say about one of our services:
“The value of such a tool is that it will be able to highlight previously unidentified improvements in technique to save energy on specific sites and provide an objective yardstick for investment decisions on controls improvements”
Most energy efficiency drives tend to look at the symptoms and not at the cause of the problem. We all understand that energy may be saved by ensuring that lights are turned off and other “soft” issues are addressed. But these according to the BRE typically will only account for about 5%-10% of potential savings. We look at he problem from the other way round and focus on the core plant itself and ask the question: “Is fuel being burning unnecessarily?” In most cases the answer is yes and in some cases for as much as 50% of the time.
We recognise that each building is unique and therefore there can be no homogeneous best practice standard. To achieve maximum efficiency each building must be benchmarked against itself, as wider benchmarks will at best only give an indication of relative efficiency.
AEC’ technology approved for the Carbon Emissions Reduction scheme
After rigorous trials and testing OFGEM have approved AEC’s technology for inclusion in CERT. This involved examination of our techniques by the BRE and Energy Saving Trust and as a result we are working with a number of local authorities to deliver savings in their communal heating systems. Out target under the scheme is to achieve 10% savings, however so far this target has been greatly exceeded and combined savings achieved to date are over 20%.
We live by the old maxim that…
“You can’t manage what you can’t measure.”
We have developed a more effective measurement tool and diagnostic techniques so that you are better able to manage your energy efficiency.
