Non-Domestic
BER Assessments
SHOW DESCRIPTION
Irish regulations state that all Non-Domestic buildings must have a Non-Domestic BER (Building Energy Rating) certificate before they leased or sold.
It applies for new and existing Non-Domestic buildings and once completed the Non-Domestic BER gives a coloured A1-G rating similar to those found on white goods, where A is the most efficient and G is the least efficient. The better the rating, the more energy-efficient the building is, and the lower the fuel bills are likely to be.
Each BER certificate is published along with an Advisory Report relating to that property. A list of improvements that can be made to improve the energy efficiency of the Non-Domestic building will be stated in the Advisory Report. The new buyers or tenants of the property are under no legal requirement to implement these recommendations.
Part L and NZEB
Compliance
SHOW DESCRIPTION
The European Energy Performance of Buildings Directive Recast 2010 (EPBD) requires all new buildings to be nearly Zero Energy Buildings (nZEB).
In Ireland, all new Non-Domestic buildings must comply with the NZEB Energy, Carbon and Renewables Targets by achieving compliance with the standards that are set out in Technical Guidance Document (TGD) Part L.
Energi IQ provides professional advice on how best to achieve TGD Part L compliance for Non-Domestic buildings.
BER Plus Reports
(Non-Domestic)
SHOW DESCRIPTION
The Advisory Report that is produced by the Non-Domestic BER software is very generic and may not be site specific. Energi IQ have developed a bespoke BER Plus Report that gives considered and costed measures to improve the current BER rating. The report investigates several site-specific measures to improve the Current BER rating. It also provides indicative capital costs for these measures along with estimated payback periods. Firstly, the report looks at individual measures for improving the BER rating and then cumulatively combines the measures in order to show the overall effect of implementing the multiple measures together.
Energy
Audits
SHOW DESCRIPTION
An energy audit is an assessment of a building or facility to identify opportunities to reduce energy use, lower carbon emissions and save money. Through an energy audit, you can learn how to better manage your energy use and improve the efficiency of your operations. Our energy audits are completed in line with the methodology set out in BS EN 16247.
The audit is carried out by a qualified energy assessor and will provide a review of the building’s energy systems, fabric and equipment. Where commercial utility billing is provided, we can conduct in-depth profiling of the building’s energy usage and will carry out comparative analysis against industry standard benchmarks i.e. CIBSE TM 46 Energy benchmarks.
The report will include a list of recommendations on how to improve the building’s energy performance, allowing businesses to make informed decisions on what changes need to be made. An energy audit is an important step in managing energy costs and ensuring that a business is taking advantage of all available energy-saving opportunities.
Dynamic Simulation
Modelling (DSM)
SHOW DESCRIPTION
Dynamic Simulation Modelling is a highly effective way to find out the building’s predicted annual energy usage before it is constructed. DSM creates a detailed thermal model of the proposed building and can produce a range of parameters about the building’s performance, such as the potential heating, ventilation and cooling loads. DSM can be used to provide detailed analysis for buildings of all levels.
DSM Modelling can also be used to undertake analysis of the ‘Prediction of Operational Energy Consumption’ for a proposed building.
The model will include the predicted operating hours, occupancy profiles, occupancy densities, thermostat set points, HVAC system operation, lighting operation and management control systems.
The model will also include Equipment and Small Power Energy usage within the building i.e. IT equipment, TVs, Kitchen Appliances, Alarm Systems etc.
Once completed the model will be able to give the prediction of operational energy consumption of the proposed building once in use.
Overheating
Assessments
SHOW DESCRIPTION
Also known as Thermal Comfort Analysis. The risk of overheating in buildings is becoming more prevalent as changing climates and global energy insecurity make the control of indoor climate increasingly problematic. Overheating occurs in a building either through inappropriate design, poor management or inadequate services. Features of a design that support lower winter heating demand (such as large areas of south facing windows, high levels of insulation, low air permeability rates and low thermal mass) can result in excessively high internal temperatures during summer months.
Detailed overheating analysis is typically performed using Dynamic Simulation Modelling (DSM) software which can analyse the occupied spaces and assess performance against criteria set by CIBSE (Chartered Institute of Building Services Engineers). Traditionally CIBSE TM52 (The Limits of Thermal Comfort: Avoiding Overheating in European Buildings 2013) guidance has been used. In recent years further guidance has been released in the form of CIBSE TM59 (May 2017) which specifically addresses the overheating risk in homes.
Energi IQ carry out TM52 and TM59 assessments to predict overheating risk for Non-Domestic and Domestic building designs using DSM software
