This will ensure a faster and more efficient service, and ultimately our aim is to provide a one stop shop for our clients. Block Energy Services adds SAP Calculations, SBEM Calculations, EPC certifcates and much more to our portfolio of services.

Here's a little more about what we do:

SAP Calculations – What Are They All About?

A SAP (Standard Assessment Procedure) is a number of calculations, including heat loss through walls, floors, roofs, heating and hot water, lighting etc, works out how energy efficient a dwelling is, showing a scale of 1 to 100 - from poor to excellent.

It is used to demonstrate compliance with Building Regulations Approved Document L1A by comparing the designed Dwelling Emission Rate (DER) with a SAP calculated Target Emission Rate (TER).

SAP 2005 works on a comparison basis that your house design was built to the 2002 Building Regulations, it will now from 2006 and onwards, have to be 20% more efficient.
So, for example, if the house cost £100 per year to run in 2002, in 2006 onwards it will only cost £80 per year to run.

Block Energy Services operate on an ethical basis, drawing on our consultants' many years of experience to get the best results for your design. If required, we will advise on the best construction to suit your requirements.

SBEM Calculations – What Are They All About?

SBEM (Simplified Building Energy Model) is a software tool developed by BRE that provides an analysis of a non-domestic building's energy consumption.

SBEM is used for non domestic buildings in support of the National Calculation Methodology (NCM) and the Energy Performance of Buildings Directive (EPBD).

The tool helps to determine CO2 emission rates for new buildings in compliance with Part L of the Building Regulations (England and Wales) and equivalent Regulations in Scotland, Northern Ireland, the Republic of Ireland and Jersey. It is also used to generate Energy Performance Certificates for non-domestic buildings in construction, for sale or let.

SBEM was developed by BRE for the Department for Communities and Local Government.

Energy Performance Certificates – What Are They All About?

Energy Performance Certificates and Display Energy Certificates educate the general public and house buyers on the efficiency of the building they are looking to purchase or use. It is now a legal requirement that all new, recently sold and rented commercial and domestic properties have an EPC.
