<p><em><strong>2 Minute Read-Time</strong></em></p><p>The Simplified Building Energy Model (SBEM) calculation is an indispensable tool for assessing the energy performance of non-domestic buildings in the UK. It's a regulatory requirement for compliance with Part L of the Building Regulations, designed to ensure that buildings adhere to defined energy efficiency standards. The cost of an SBEM calculation varies widely, influenced by various project-specific factors.</p><h3>Cost Range and Influencing Factors</h3><p><br>Typically, the cost for an SBEM calculation can vary from £350 to £5,000, reflecting the diversity and complexity of the projects assessed​​. Key factors influencing this cost include the size of the development, the complexity of the building design, the type of project (e.g., new build, extension, refurbishment), additional services required, location, and the urgency of the project deadlines.</p><h3>Introducing Our Pricing Table</h3><p><br>To provide you with a more transparent understanding of potential costs, we have developed a detailed pricing table that outlines our specific charges for SBEM calculations based on various project parameters. This table is designed to help you estimate the costs for your project more accurately.</p><table border="1" style="border-collapse: collapse; width: 160%; margin-left: auto; margin-right: auto;" data-mce-style="border-collapse: collapse;

Our personalised pricing table is intended to demystify these costs further, providing you with clear, upfront information to help in your project planning. Consultation with a qualified assessor early in the design process is recommended to get a precise quote and ensure compliance efficiently.</p>

Understanding the Costs of SBEM Calculations: Factors, Influences, and OurPricing

<p><em><strong>5 Minute Read-Time</strong></em></p><p>In today's rapidly evolving real estate landscape, multinational corporations (MNCs) like Knight Frank, Cushman &amp; Wakefield, and Land Securities Group PLC are increasingly recognising the imperative to enhance their commercial buildings' energy performance. This drive is not only motivated by a desire to improve energy credentials for sale, letting, and ESG (Environmental, Social, and Governance) compliance but also by the urgent need to contribute to global decarbonisation efforts.</p><h3>Global Emissions and the Urgency for Energy Efficiency</h3><p>Buildings, both residential and commercial, are responsible for a significant portion of global energy use and related greenhouse gas (GHG) emissions. In 2022, direct CO2 emissions from building operations decreased to 3 Gt, while indirect emissions surged to nearly 6.8 Gt, reflecting an increased reliance on electricity. This juxtaposition underscores the pressing need for the buildings and construction sector to accelerate decarbonisation efforts to align with Net Zero Emissions (NZE) scenarios​​. Building-material-related GHG emissions are expected to rise from 3.5 to 4.6 Gt CO2eq annually by 2060 under current trajectories, emphasising the critical role of material efficiency and the adoption of zero-carbon-ready buildings in mitigating emissions​​.</p><h3>The Strategic Advantage of Cross-Border Energy Performance Consultancy</h3><p>For MNCs with extensive real estate portfolios that span multiple countries, centralising energy performance evaluations with a single consultancy offers unparalleled benefits:</p><p><strong>Quality Assurance:</strong> A unified approach ensures consistency in energy performance calculations, significantly reducing the risk of discrepancies in data quality and accuracy. This is vital for making informed decisions about property investments, renovations, and compliance strategies.</p><p><br><strong>Comprehensive Building Energy Data Management:</strong> Centralised data management facilitates a holistic view of a portfolio's energy performance, enabling strategic planning for energy reduction, ESG compliance, and identifying opportunities for cost savings and efficiency improvements.</p><p><br><strong>Adaptation to Global Policies and Innovations: </strong>With countries and regions such as the EU, China, Japan, and the USA implementing stringent energy performance and decarbonisation policies, a consultancy with a global purview is better positioned to navigate these diverse regulatory landscapes and leverage best practices across borders​​.</p><h3><br>Call to Action for Real Estate Giants</h3><p>The construction and operation of commercial buildings account for more than one-third of global energy-related emissions, with operational energy use alone representing about 30% of global final energy consumption​​​​. This stark reality, coupled with the sector's potential for significant emission reductions through improved energy efficiency and the adoption of zero-carbon and renewable energy technologies, highlights the urgent need for MNCs to adopt a more strategic, cross-border approach to energy performance management.</p><p>By centralising energy performance consultancy services, real estate MNCs can ensure consistent, high-quality data across their portfolio, enabling them to meet global ESG standards, reduce operational costs, and contribute meaningfully to the global fight against climate change. The time for action is now, as the window for achieving global decarbonisation goals narrows. Real estate giants have a pivotal role to play in shaping a sustainable future, and by embracing a unified approach to energy performance, they can lead the way in the transition to a greener, more energy-efficient world.</p><p>In conclusion, the benefits of a cross-border energy performance strategy are clear. Not only does it offer a path to enhanced energy efficiency and compliance with ESG criteria, but it also positions MNCs at the forefront of global efforts to combat climate change and promote sustainable development. The question for CEOs, CFOs, and key decision-makers in the real estate sector is not if they can afford to implement such a strategy, but whether they can afford not to.</p>

Harnessing Energy Performance Across Borders: A Strategic Approach for Global Real Estate

<p><em><strong>4 Minute Read Time</strong></em></p><p>In the realm of building energy efficiency, the methodologies of SBEM Calculations in the UK, Section J and JV3 in Australia, and ASHRAE Standard 90.1 in the United States represent significant pillars. Each of these frameworks not only reflects the environmental and regulatory landscape of its origin but also embodies a distinct approach to achieving sustainability in the built environment. This analysis delves into the intricacies of these methodologies, providing an in-depth examination of their principles, applications, and potential for global standardisation.</p><h3>SBEM Calculations (UK)</h3><p><br>The Simplified Building Energy Model (SBEM) is an essential tool for assessing the energy performance of non-domestic buildings in the UK. It's designed to support compliance with Part L of the Building Regulations, which focuses on conserving fuel and power. SBEM calculations evaluate a building's carbon emissions, ensuring they do not exceed the Target Emission Rate (TER). This process involves analysing building geometry, HVAC, lighting, and other factors influencing energy consumption​​​​.</p><p>SBEM's unique contribution to the energy efficiency landscape is its compatibility with the UK's specific climate, construction practices, and regulatory standards. Its use of dedicated software for energy modelling allows for precise compliance assessments, reflecting a tailored approach to sustainability within the UK's built environment.</p><h3>Section J and JV3 (Australia)</h3><p><br>Section J of the National Construction Code sets forth energy efficiency standards for non-residential buildings in Australia. It mandates specific construction practices and systems, including HVAC and glazing, to minimise energy use.

Moreover, the sector faces a skills shortage, underscoring the need for investment in specialist professions and training​​.</p><h3>Understanding Overheating: Its Growing Concern in the UK</h3><p>Overheating in buildings, especially homes, is an escalating concern in the UK. The phenomenon refers to conditions where excessive heat leads to uncomfortable and potentially health-hazardous indoor environments. Factors contributing to this issue include climate change, urban heat islands, and building design that does not adequately consider thermal comfort. To address this, the UK Green Building Council (UKGBC) emphasizes the need for the built environment to adopt circular and regenerative approaches, moving away from traditional resource-intensive practices​</p><h3>Expanding on Types of Overheating Assessments</h3><p><strong>Approved Document O (AD O)</strong></p><p>AD O is a part of the UK building regulations, specifically addressing the mitigation of overheating in new residential buildings. It sets standards for design and construction to prevent excessive heat in homes. The document outlines specific requirements for glazing areas and shading, depending on the risk level of the location (high risk or moderate risk) and the orientation of the building facades. For instance, the glazing limits and shading requirements are defined based on the compass direction of the façade. Furthermore, AD O prescribes standards for ventilation, such as the minimum free area for bedrooms, which is calculated as a percentage of the floor area of the room. AD O also includes a dynamic thermal modelling method, which requires a report demonstrating compliance with CIBSE's TM59 assessment of overheating​​​​​​.</p><p><strong>CIBSE TM59</strong></p><p>This guide by the Chartered Institution of Building Services Engineers focuses on residential buildings. It provides a detailed methodology for assessing the risk of overheating in new dwellings, considering factors like location, building orientation, and thermal properties. TM59 uses dynamic thermal modelling to evaluate indoor temperatures throughout the year under different scenarios, ensuring the comfort of occupants and adherence to health standards.</p><p><br><strong>CIBSE TM52</strong></p><p>This assessment is used for non-residential buildings, such as offices and schools. TM52 sets out criteria to prevent overheating and ensure thermal comfort for building users. It includes parameters like the number of hours during which internal temperatures exceed certain thresholds. The assessment takes into account various factors such as building design, occupancy patterns, and local climate conditions.</p><p><br><strong>BB101</strong></p><p> Mainly focused on educational buildings, BB101 provides guidelines for ventilation, thermal comfort, and indoor air quality. It sets out specific criteria for assessing overheating risk in schools, considering unique factors like higher occupancy and specific usage patterns of educational buildings.</p><p><br>Each of these assessments serves a distinct purpose and caters to different types of buildings, ensuring that the risk of overheating is minimized while maintaining comfort and health standards. The emphasis across these assessments is on passive cooling strategies and building design optimizations, with mechanical cooling considered as a last resort due to its higher energy consumption and carbon footprint.</p><h3>How To Mitigate Overheating Risk</h3><p>Mitigating the risk of overheating in buildings is a crucial aspect of sustainable building design, especially in the face of climate change and urban heat island effects. It involves a combination of strategies aimed at reducing internal heat gains, enhancing cooling through passive means, and, if necessary, employing active cooling systems. These strategies not only enhance the comfort and health of occupants but also contribute to energy efficiency and environmental sustainability. Below are detailed elaborations on various mitigation tactics:</p><p><strong>Improved Building Insulation:</strong> Effective insulation is key to maintaining a stable indoor temperature by reducing heat gain in summer and preventing heat loss in winter. Insulation materials should be chosen based on their thermal performance, durability, and environmental impact. This approach not only mitigates overheating but also enhances overall energy efficiency.</p><p><br><strong>Enhanced Natural Ventilation:</strong> Designing buildings to maximize natural airflow can significantly reduce indoor temperatures.
