Need to know where to start when it comes to making your home more energy efficient?
At Energy efficient you, we’re here to help you improve your energy efficiency. We will complete a detailed survey of your property and produce an energy report using the RdSAP methodology.
A retrofit assessment is an in-depth assessment of a property bases on the following:
Retrofit assessors play a significant role within the PAS 2035 process as they collect and provide property data and information. PAS 2035 is a specification that is referred to as ‘whole-house’ or ‘whole-building’ retrofit. This is an approach to the installation of energy efficiency measures (EEMs) which considers the requirements of the entire building, both from a technical position that consider factors such as occupancy comfort.
Every home that is to be subjected to energy retrofit work must first be assessed by a retrofit assessor. The main responsibility is to collect and provide information to the retrofit coordinator about the dwelling.
Our retrofit assessor will complete a survey of your property including construction details and layout survey, what your existing heating and hot water provision is and how it is controlled. Our retrofit coordinator will identify any underlying issues including damp or condensation.
As retrofit assessors we aim to gain an understanding of how you use the property (heating patterns, ventilation, energy bills) and the desired outcome from the energy saving improvements.
As a result of the retrofit assessment an energy report will be produced as a starting point using the RdSAP methodology.
The condition report will also detail any building defects like damp/condensation issues or any other building problems that require attention before any energy saving measures can be installed.
Finally, an occupancy evaluation will look at your previous year’s energy bills and the way you use energy in your house. This combined with the energy report will show a clear understanding of how energy is used and where improvements can be made.
Depending on the size of the house and what your requirements are, a survey can take approximately 2 – 3 hours, we also spend a further half day working on desk top study.
Retrofit assessors will split the survey into two parts – the desk top study and the site survey. It is beneficial to complete the desk-based study first before visiting a property.
The information from the desk-based study needs to be verified in the on-site survey at the property.
The desk-based study involves:
The property survey involves:
The validity period of a retrofit assessment can vary widely based on factors such as the nature of the assessment, the specific improvements made, regulations, and the industry standards in the relevant region. Here are a few considerations:
In some cases, regulatory bodies might specify a timeframe for re-assessments. For example, certain building codes or energy efficiency standards might require periodic re-assessment to ensure ongoing compliance.
The validity of a retrofit assessment could also be influenced by rapid technological advancements. If new technologies emerge that offer significantly improved energy efficiency solutions, it might be advisable to revisit the assessment sooner to take advantage of these advancements.
Changes in the way a building or system is operated can impact its energy efficiency. If there are substantial changes in occupancy, usage patterns, or operating procedures, a reassessment might be necessary.
Changes in energy prices or policies, such as the introduction of new incentives or regulations, might necessitate a reassessment to evaluate the financial feasibility of further improvements.
Given these considerations, it’s essential to consult with our energy efficiency experts to determine the recommended frequency for reassessments. While there might not be a universally fixed validity period for retrofit assessments, staying informed about changes in regulations, technologies, and best practices will help you make informed decisions about when to revisit and update your energy efficiency strategies.
The process of a retrofit assessment involves a series of steps aimed at evaluating an existing structure, system, or facility to identify opportunities for improvement, upgrade, or modification. This assessment is commonly performed to enhance energy efficiency, safety, compliance with regulations, and overall performance. Below is a general outline of the process:
At Energy Efficient You, we don’t just help you with EPC assessments. We can also help you access government grants to improve the energy efficiency and heating of your home! Here are just some of the grants we can help you with:
