Non-Domestic Energy Performance Certificates play a crucial role in promoting energy efficiency and sustainability in buildings. They provide valuable information to property owners, tenants, and potential buyers, enabling them to make informed decisions to reduce energy consumption, lower costs, and minimise environmental impact.

 We use ApacheHVAC to create an energy model of the building and its HVAC systems. This involves inputting building characteristics, such as geometry, construction materials, and occupancy patterns, as well as detailed specifications of the HVAC components, including equipment types, capacities, control strategies, and setpoints.

We Utilise specialised simulation software IESVE module Radiance to assess the impact of different design strategies, such as window sizes, glazing properties, shading devices, light shelves, or interior reflectance, on the daylighting performance. The simulations can help determine the most effective design choices to maximise daylighting benefits and minimise glare or excessive solar heat gain.

PHPP is a detailed design and assessment tool used to evaluate the energy performance of domestic buildings in line with the Passive House standard. It provides a rigorous methodology for modelling insulation, airtightness, ventilation, and renewable energy integration, enabling designers and assessors to optimise comfort and minimise energy demand.

By applying PHPP, energy professionals can identify opportunities to reduce consumption, cut carbon emissions, and deliver homes that achieve exceptional efficiency and sustainability.

SBEM  and DSM  are essential tools used in the UK to evaluate and optimize the energy performance of buildings. SBEM provides a simplified approach to assess non-domestic building energy efficiency, while DSM offers a more detailed and dynamic simulation of a building's energy usage. Together, they enable energy assessors and professionals to identify areas for improvement, leading to reduced energy consumption, lower carbon emissions, and increased sustainability in buildings.

By utilising CIBSE and NABERS methodologies for operational energy simulation, building owners, operators, and energy professionals can assess and improve the energy performance of buildings. These approaches provide valuable insights into energy consumption patterns, identify areas for optimisation, and help guide decision-making to achieve greater energy efficiency and sustainability.

SAP plays a vital role in ensuring that domestic buildings in the UK meet the energy efficiency standards set by the Building Regulations. SAP enables  energy assessors and professionals to evaluate and optimise the energy performance of buildings, leading to reduced energy consumption, lower carbon emissions, and increased sustainability.

A Heat Pump Technical Advisor is an independent SEAI‑registered expert who assesses whether a home meets the required Heat Loss Indicator (HLI) for a heat pump grant. They carry out a technical survey, advise on any insulation or fabric upgrades needed to make the property “heat pump ready,” and provide a clear report to help homeowners improve efficiency and qualify for SEAI funding. Their guidance ensures heat pumps can operate effectively while supporting greener, lower‑cost home heating solutions

By utilising dynamic simulations for thermal comfort analysis, designers and engineers can make informed decisions to optimise building design, HVAC systems, and control strategies. These simulations enable a more comprehensive understanding of how various factors interact and affect occupant comfort, leading to the creation of buildings that provide optimal thermal conditions throughout the year

LZC feasibility studies, also known as Low or Zero Carbon feasibility studies, assess the viability and practicality of incorporating low or zero carbon technologies in a project or development. These studies aim to evaluate the potential for reducing carbon emissions, increasing energy efficiency, and utilising renewable energy sources.

BER is the official energy performance rating system for both domestic and non‑domestic buildings in Ireland, assessing factors like insulation, heating systems, ventilation, and renewable technologies to indicate overall efficiency and carbon impact. Domestic BERs are completed using the DEAP methodology, while non‑domestic buildings use the NEAP framework. BRIRL works alongside these systems to support regulatory compliance and best‑practice energy performance reporting. Together, BER and BRIRL help building owners and professionals reduce energy use, cut emissions, and meet national sustainability standards
