DRNDesign offers a complete range of mechanical and electrical consultancy services.  Our engineers have a wealth of skills and experience in all major design sectors, including specialist fields such as residential, education, council homes, office fit out and commercial building design.

Mechanical and Electrical Design for Sustainable Building Performance

 

We design mechanical and electrical, project manage, public health and offer technical services.  Ideally, the service will provide early design consultations with the architect, client and other design practitioners in order to fully understand the needs of the customer. 

 

In our experience, especially where low-energy construction is needed, we provide the most meaningful decisions needed. As the design progresses we provide our customer with updated progress on each phase.

If required, our service will provide advice on procurement options and tenderer/contractor selection.

 

We provide assistance to the quantity surveyor and assist in the preparation of cost plans; however, we are not cost consultants.  In smaller projects where the hiring of a M & E Quantity Surveyor is not warranted, we are able to provide guidance on plan cost. 

 

All the information drawn will be created using the latest CAD software, drawing on the backgrounds of the architect wherever possible.

 

We take  a rational approach on all designs presented - assuming the concept is correct, the software sent is sensible and contractors are well managed - aiding us to provide the customer the best value for the building.

 

What are Display Energy Certificates (DECs) & Energy Performance Certificates (EPCs)?

Energy certificates assess and rate the energy performance of buildings. There are two main types of energy certificate:

Display Energy Certificates (DECs) provide an evaluation of the energy efficiency of public buildings. The validity period is either one year or ten years, determined by the building's floor area. Buildings are rated on a scale from ‘A’ (most efficient) to ‘G’ (least efficient). DECs must be accompanied by an Advisory Report, which outlines cost-effective recommendations for improving the building’s energy rating.

Energy Performance Certificates (EPCs) are required for all other properties at the point of construction, sale, or lease. An EPC offers detailed information regarding the property’s energy efficiency and suggests possible improvements. The EPC rating, also ranging from ‘A’ to ‘G’, indicates projected heating and lighting costs for prospective buyers or tenants. In accordance with the Minimum Energy Efficiency Standard, commercial properties cannot be rented if they hold a rating below E, unless it can be demonstrated that all reasonable measures have been undertaken to raise efficiency above an E rating. This requirement is expected to move to band B by 2030, marking a significant increase in energy-efficiency standards for rented commercial buildings.

  • As for DECs, ratings are calculated using actual energy consumption data collected by our assessor, who follows approved methods. An Advisory Report is also prepared to outline energy improvements that can lower costs and carbon emissions.

  • As for EPCs, an accredited assessor conducts a site audit, then uses the gathered information in government-approved modelling software to simulate building performance. The operational rating and grade are logged on the Government register for EPC issuance.

 

 

 

 

Mechanical and Electrical Service Defects Investigation

 

We are reminded every day of the tragic yet inevitable ramifications of service defects and degradation. You need pathology knowledge on your part if you are worried about knowing how this occurs, why it can happen and what can be done to fix it.

 

Why are these attributes so important for the best building defects advice?

The important thing is to diagnose the cause(s) of failure quickly and accurately, whether you are dealing with design deficiencies, improper operation, poor construction, lack of maintenance or statutory compliance problems.

 

Our teams have experience working in all types of buildings, including commercial, residential, recreational and industrial. In clear terms, we can provide cost-effective, service maintenance and robust deliverable solutions.

Employer's Agent

 

Where your project needs the representative of an employer to arrange and administer the contractual process, such as design, witness installation services and service maintenance; we are highly qualified to work for you whether for new construction or renovation projects.  Throughout each stage consisting of planning, construction, building and completion phases, we have a well-developed management processes.  

 

This helps us to measure and manage the project from beginning to end, combined with strong technical skills, an analytical approach and proven instruments for consistent reporting and communication.
