BER and DEAP Assessments - Case Study 2
Perhaps you are thinking of undertaking an energy assessment of your home?
Perhaps you are interested in understanding the potential impacts of certain changes/improvements on the energy performance of your dwelling?
The Building Energy Ratings (BER) will show you how to add value to your home and also highlight ways in which you can improve the energy rating of your home (e.g. improve from a E or D to a C )
This report has been prepared by Conservation Engineering Consultants Ltd. The report details the findings of the Dwelling Energy Assessment Procedure (DEAP) calculations carried out on three standard dwellings with constructions typical of mid 1990 standards.
Each dwelling was initially assessed on the basis of Building Regulations Part L 1991 compliant designs to establish the ratings that would be achieved.
A step by step analysis is then carried out to highlight the improvements that will be achieved in the energy ratings as energy efficient design features are incorporated in the design.
Each unit was then assessed on the basis of Building Regulations Part L 2006 and 2008 compliant designs in order to show comparison with current regulations.
It is worth noting that the results achieved by the three dwellings in this report should only be taken as a guideline and each individual dwelling should be assessed on its own merits and according to its own specification.
The following are the three standard dwellings chosen with constructions typical of mid 1990 standards:
1) Mid Block Dual Aspect Apartment (77m²)
2) 3 Bed Semi-Detached House (91.5 m²)
3) 4 Bed Bungalow House (103m²)
The study initially shows default specifications and U-Values for typical mid 1990's dwellings - as found in the DEAP software.
Typical Mid 1990’s Dwelling Specification
The following sections outline some suggested improvements for each of the three dwelling types (e.g. improved glazing, changed heating system etc) and the estimated results of those improvements.
