SAP Calculations for New Buildings to assist with design and demonstrate compliance in relation to required TER / DER calculations – a requirement for your Building Warrant Application


New build houses must be

more energy efficiently than ever. Without a SAP assessment, you  won’t be able to start

work on site.


We can also provide

the following:


  • U Value calculations Condensation Risk Analysis


  • Extension Heat Loss (Compensatory) Calculations


EPCs are mandatory for all new and existing buildings. Buildings when constructed, sold or rented out, including homes, public sector buildings and business premises will require an Energy Performance Certificate.


ScottishSAPassessor can provide EPCs for new build dwellings and for existing dwellings.


EPCs are required in order

to obtain your completion certificate and for Renewable Heat Incentive Applications.


A Section 6 Certificate (supplied by an RIAS Energy Design Certifier) will:


  • Speed the warrant application process


  • Give confidence that the home in question fully complies with the regulations


  • Deliver particular benefits for historic or traditional homes

An Energy Options appraisal

can be carried out to assist you with decision making for your project. It will review options

and analyse relative costs and benefits and should help develop a value for money solution for your project.

Energy Options Appraisals


The Passivhaus standards strengths lie in the simplicity of its approach; build a house that has an excellent thermal performance, exceptional airtightness with mechanical ventilation. This robust approach to building design allows the designer to minimise the 'Heating Demand' of the building which can then then be recovered and circulated by

a (MVHR) unit.

Quick Start Guides

This guide is produced to meet the aspect of optimising the performance within Section 7: Sustainability of the Scottish Building Standards Technical Handbooks

It should provide guidance to the occupants on the ways in which the specific dwelling is intended to function and how to optimise its performance to get the best out of the house and keeping bills and carbon footprint as small as possible.


This is additional to the written information to be provided to occupants under Section 6.
