The London Plan
Challenge
The London Plan provides a broad set of guidelines covering the planning, construction and operation of London over the next 20-25 years. It has significant influence over the design of the built environment, specifically, the energy, environmental, sustainability, air quality and whole life cost approaches to optimising the design and operation of buildings. Comprehensive monitoring of energy demand and carbon emissions are required, carbon emissions must be reduced 30% more than the current building regs requirements, and dynamic overheating modelling should be undertaken in line with the CIBSE guidance.
Solution
- IESVE software provides tools for:
- Dynamic thermal and energy capabilities for modelling overheating, loads, energy demand, carbon emissions, air quality, integration of renewable energy calculation of energy costs
- Solar and daylighting, allowing you to optimise the use of solar energy on site, predict energy yields, solar resource assessments, daylighting and climate based daylight metrics
- Micro-climate studies and urban heat island impacts
- Parametric modelling and analysing multiple scenarios in a quick and accurate simulation, thus providing significant speed and support for assessing scenarios against a baseline model
- Partnership with One Click LCA enables whole life cycle costing including life cycle analyses
CIBSE TM52: The Limits of Thermal Comfort: Avoiding Overheating in European Buildings
Challenge
Overheating has become a key issue for building design, and the need to reduce energy consumption whilst dealing with climate change has reduced the options available to build comfortable, low-energy buildings. Additionally, in the UK buildings are designed for cooler temperatures in the winter, but this can lead to overheating in the summer months. CIBSE TM52 informs designers, developers and others responsible for defining the indoor environment in buildings.
Solution
- IESVE allows users to analyse TM52 directly within the software using an output in the viewer platform.
- Easy to use, with just the click of a button needed to extract the results needed for TM52 once a dynamic simulation has been run using the VE's Energy Simulation application.
Overheating: Approved Document O: Building regulation in England setting standards for overheating in new residential buildings
Challenge
Approved Document Part O of the UK Building Regulations addresses overheating in homes. The two methods for compliance are the simplified method and the second method is the dynamic thermal analysis to predict the overheating risk and enable the designer to provide mitigation strategies.
Solution
IESVE dynamic thermal modelling can be used to comply with the dynamic thermal modelling solutions for Part O.
The software has its own dedicated workflow enabling the user to establish the rismk of overheating and through iteration provide a solution to limit the overheating and ensure it is within the pre-described limits set by the approved document.
The solution is based upon CIBSE TM59 but uses specific opening criteria for windows all of which are built into to software for ease of use.
The dynamic models are run using CIBSE Weather Data.
BREEAM
Challenge
Achieving a high number of credits can be difficult, and the cost of additional credits to achieve your target BREEAM rating can quickly become prohibitive. A BREEAM Excellent score requires a credit score of 70% or above, and an Outstanding score requires 85% or above.
Solution
IESVE provides a wide range of analysis capability that is perfectly suited for attaining BREEAM credit compliance, helping you broaden your firms BREEAM assessment capability.
- Combined use of IESVE and One Click LCA offers a solution to attain over 50 BREEAM credits.
- Use of IES TaP for BREEAM provides a secure, cost effective and easy to use online project management system to streamline, manage and automate the BREEAM certification process, making it even more efficient.
BB101
Challenge
BB101 provides guidance on ventilation, thermal comfort and indoor air quality in schools including ventilation standard for spaces, guidance on room temperatures and draughts, detailed calcuation methords and reducing sources of indoor and outdoor pollutants.
Solution
IESVE is perfectly suited to evaluate all three of these important factors.
- Dynamic simulation software allows for natural ventilation, mixed-mode and mechanical ventilation strategies to be coupled with heat/energy exchange along with assessing indoor air quality.
- VE routinely used by experts around the UK to desing and optimise the environmental, energy and sustainability aspects of the school’s design.
- Daylight tools allow an enhanced analysis of climate based daylight metrics, daylight factors and CFD tool is used extensively to model draughts and air mixing.
WELL Building Standard
Challenge
The WELL Building Standard is a certification scheme developed by Delos and the International WELL Building Institute™ to highlight the benefits of integrating occupant health and wellbeing in the design, construction and operation of our buildings. The Standard is organised into seven main ‘concepts’; Air, Water, Nourishment, Light, Fitness, Comfort and Mind. All are applicable to three general building project typologies; new & existing buildings, new & existing interiors and core & shell compliance.
Solution
The IESVE software offers many outputs that are relevant to the seven concepts of the WELL Standard. Thermal comfort indices for ASHRAE 55, indoor air quality, mean age of air, visual comfort, daylight performance using Dynamic Daylighting and sky view are just some examples of appropriate modelling outputs for WELL credits.
UK Building Regulations
Challenge
Compliance software must be used to produce an output report showing compliance has been achieved for UK Building Regulation criteria.
Solution
