Commercial Energy Performance Improvement Services (EPC+ Service)

Low Carbon Energy Assessors (LCEA) Ltd provides extra added value services in comparison to our competitors when it comes to Professional Commercial Energy Assessments.

We offer various levels of enhanced energy assessments tailored to our clients’ specific requirements. From high level benchmarking exercises i.e. our Energy Conservation Opportunities Assessment Service (EPC+ Service), right down to a fully detailed quantified energy auditing service, called our Enhanced Energy Conservation Opportunities Assessment Service (Enhanced EPC+ Service).

We provide what if scenarios and remodel the properties by carryout 3D energy simulation services to enable us to identify the most cost effective solution to improve the energy efficiency of our client’s building / portfolios. We illustrate the results within our technical energy report, which is written in laymans terms so that anybody can appreciate and understand what our findings are from the ‘Boardroom’ through to an ‘Operational’ delivery point of view.

We clearly define and identify what the most suitable energy efficiency improvement scope of works would be worth considering. We illustrate within the report the before and after’ results which can either be benchmarked against the Asset Rating, which is also known as the Commercial Energy Performance Certificate, or against the Operational Rating which is also referred to as the Display Energy Certificate. We also benchmark our findings against other Professional energy efficiency publications such as CIBSE / RICS / Carbon Trust Guides and against are own in-house energy efficiency database.

We are Chartered Quantity Surveyors, specialise in Building Engineering Services and have the Professional knowledge and experience in surveying Commercial Properties along with advising on financial costs. We provide you with a report with a financial executive summary including payback analysis, NPV, IRR, KWh, CO2 benchmark comparisons.

Previous projects: –

We have been involved with preliminary energy performance assessments (asset ratings) with various large Consultancy and Construction Companies within the UK. Producing Commercial EPCs of the building / portfolios before any refurbishment works or energy efficient measures were carried out.

The purposes of these exercises was to remodel the existing building with energy efficient measures specifically provided by the client / client’s design team and or just specifically from LCEA Ltd, example of the list of measures and improvements illustrated within table 2.  The remodeling of these scenarios, can be either be based on each individual improvement item or accumulative.

This services clearly illustrates what the each improvement measure can bring in terms of improving the energy performance certificate, Display energy certificate and from the view point of energy, carbon emissions, before proceeding with any works. In essence our Appraisal achieves the following:

i) Establishes the current commercial energy performance certificate (Asset rating) before implementing any refurbishment or energy efficient works.

ii) Establishes what the Commercial EPC or Display Energy Certificate rating could be achieving based on the energy efficient measures identified, example contained within table 2.

iii) Identify the most cost effective solution or solutions for the client. At LCEA Ltd, we illustrate what the current energy performance is and how it can potentially be improved. We would also compare the property / portfolio against the current Building Regulation Part L and or against any recently proposed Part L updates being introduced.

Enhanced Energy Conservation Opportunities – (Detailed quantified energy auditing service)

Our detailed assessments identify the energy and CO2 reductions, by investigating the operational, no-cost, low-cost, medium-cost, high-costs and CAPEX improvement measures that can be implemented at the asset by the Landlord and the associated FM service providers.

We assess the potential Heating, Ventilating Air Conditioning (HVAC) & Building Services’ energy savings for the property by conducting a detailed energy assessment of the facility, compiling the relevant energy utility data to determine overall energy utilisation. Our enhanced energy assessments identifies areas of energy savings and equipment deficiencies through analysing mechanical and electrical systems, sequences and operating schedules, and total cost of current HVAC and building services operations.

The identified no/low cost measures are further prioritised for ease ofimplementation based on the impact on the clients and business of the property / portfolio:

• Transparent measures are those that can be implemented without impacting the site business;

• Behavioural change measures are those that can be implemented for little or no cost but have some impact on the site condition or business operation;

• Measures that can be implemented as operating expense (typically offering simple paybacks within one year);

• Measures needing investment capital and/or contractual (re)negotiation with existing service provider(s).

A number of the measures presented will require in-depth engineering review in order to fully implement. In this case it is recommended the site team develop a detailed action plan, cost estimate, schedule of implementation through engagement with suppliers and close liaison with onsite teams in order to collate enough detail to present the project for funding and/or joint approval by occupiers of the office space. Other measures, especially the no/low cost measures can be implemented as soon as approval of site leadership is obtained.

We recommend: –

As measures are completed the operational staff should be trained on the operation of any new equipment, including all the hardware/software capabilities, and the effect that these changes will have on the operation of the building and their individual tasks.

This training is a critical component with regards to minimizing energy consumption and will need to be on-going to address any changes in the staff. Always continue with your energy conservation opportunities as they will always change and develop with the changes within each business.

Therefore, monitoring and continual review of efficiency targets is another component of maintaining sustainable savings and therefore procedures will need to be put in place to regularly check the compliance of the individual measures with the operational protocols to achieve savings.

There remain a significant number of opportunities with major energy efficiency saving potential yet to be fully scoped, which is dependent upon general building operational / capital planning decisions (e.g. decision to invest in new efficient equipment such as HVAC & lighting types).

We identify these opportunities and list them within our executive summary matrix. We would also recommend a re-review of the sites HVAC performance again and in all likelihood probably generate more energy conservation opportunities, which can be scoped in greater detail. Should you have any queries regarding our Enhanced Energy Auditing Services / Energy Conservation Opportunities please do contact Robert Corbyn MRICS Director from Low Carbon Energy Assessors (LCEA) Limited on his Mobile +44 (0)780 441 4170 or our London office.
