• Undertaking Target Emission Rate (TER) calculations using SAP/SBEM for simple buildings. [SM7M, SM9M]
• The energy and sustainability assessment methods and certificates used in the United
• Producing design recommendations for buildings to deliver energy efficiency improvements. [SM7M, SM8M, EA5M, D9M, P12M, P9m]

Subject Specific Practical Skills

Having successfully completed this module you will be able to:

• Construct a basic TRNSYS simulation model or SAP simulation model. [EA6M, EA7M]
• Conduct a simple walk through energy performance assessment of a building. [EA5M, EA7M, EL13M, G1]
• Use SAP/SBEM tools available for building performance assessment. [SM9M, EA6M, EA5M, D9M, D10M, EL11M, EL12M, P12M, P9m]

Transferable and Generic Skills

Having successfully completed this module you will be able to:

• Produce a concise technical report. [G1]
• Problem solving. [EA6M, EA5M, EA7M, D9M, D10M]
• Use assessment methods to support decisions. [EA6M, D10M, EL13M, P9m, P10m]
• Make appropriate decisions based on judgement. [EA5M, D9M, EL13M]

The module links legislation with the technical understanding required to demonstrate the compliance of a building design approach. It comprises the following:

1. An overview of the following regulations and assessment tools: BREEAM (BRE Environmental Assessment Method), EPBD (EU Directive on the Energy Performance of Buildings), Part L of the

Building Regulations, EPC (Energy Performance Certificates), DEC (Display Energy Certificates), SAP (Standard Assessment Procedure), SBEM (Simplified Building Energy Model), Code for

Sustainable Homes, SPEAR (Arup). Pure energy rating systems such as SBEM and SAP will be bridged to more broad sustainability based rating systems such as BREEAM. The students will be given an overview of each tool but the focus will be on building regulation compliance assessment using SBEM, Energy Performance Certificates, Display Energy Certificates (for public buildings) and the Code for Sustainable Homes (for domestic buildings).

2. Building physics, including heating energy requirement calculations for simple buildings using the traditional elemental methods.

3. Valuing of microgeneration / low and zero carbon technologies in carbon calculations (photovoltaics, solar thermal, microwind, ground source and air source heat pumps, micro-CHP, biomass boilers and heating systems). Calculating carbon payback times of low carbon technologies.

4. EPC and DEC certificates – the difference between ‘design’ and ‘in operation’ energy performance.

5. Measuring energy performance in walk through surveys and long-term data monitoring.

6. Understanding human comfort and user behaviour.

7. Dynamic computer simulation. Basic principles of dynamic simulation and introduction to software simulation packages.

Teaching and learning methods

The course will comprise lectures and computer classes on the use of the SAP (NHER Plan

Assessor), iSBEM and TRNSYS software tools to model simple case study buildings.
