- Case Studies
With Combined Heat and Power (CHP), commercial building operators can reduce running costs and greenhouse gas emissions while keeping occupants comfortable and happy.
Most of the costs associated with running a commercial building are fixed. Energy is one of the few overhead’s operators can exercise a degree of control over in new and existing office buildings. Reducing energy consumption will not only help save money and improve energy sustainability, but it can also improve working conditions and, therefore, boost productivity.
Edina’s MWM gas engines can achieve efficiencies of 90%, which is almost twice the efficiency of sourcing power from the grid and thermal energy from on-site boilers.
Combined Cooling Heat and Power (CCHP), which is also known as trigeneration, uses a similar process where some of the recovered heat is used to generate chilled water that can be used for air conditioning and refrigeration.
CHP and Combined Cooling, Heat and Power (CCHP) systems can be used anywhere that there is a demand for heat or cooling along with electricity. For businesses, effective heating and cooling is essential for creating happy and productive workplaces.
But optimising temperature control comes at a price. According to the Carbon Trust, heating, ventilation and air conditioning (HVAC) systems are the most energy intensive processes in an office environment. Heating alone accounts about one-third of a typical office’s energy consumption.
Cogeneration, or CHP can dramatically reduce energy consumption and provide 'free' heat. This high efficiency method of onsite energy production captures the heat produced as a by-product during power generation and recycles it to heat spaces and provide hot water.
For commercial building operators, the key advantage of an on-site CHP generator is that it will typically generate electricity at a cheaper rate than you can procure it from the grid.
The positive 'spark spread' of low carbon natural gas is increasing the financial benefits of CHP. 'Spark spread' is the differential between the price of energy and the cost of fuel used to generate that energy. Whilst power costs have soared, the spark spread favours a strong economic case for using on-site CHP.
The economic viability of CHP is demonstrated by the short payback time on installing a CHP engine. In some cases, it is as low as two or three years, providing a key opportunity for savings on systems with a typical lifespan of 15 years.
Due to its exceptional efficiency a low carbon natural gas CHP system can complement other low and zero carbon measures to help organisations work towards their net-zero ambitions.
As a market-leader in the supply, installation and maintenance of CHP and emergency back-up power systems, Edina has completed several energy saving projects within commercial buildings.
