Energy Assessors and Commercial Property Owners 
 
Technoshade firmly believe effective solar shading can make significant reductions to energy consumption both commercially, and at home. 
 
The desire to reduce our collective carbon footprint is a major driver of government and EEC initiative at present. 
In the UK, 40% of all energy consumption is building related. Air conditioning and heating are the major contributors to the ever growing cost of gas and electricity bills, not to mention their impact on our environment. 
 
A growing amount of legislation concerning energy use in the built environment is also being passed, with growing emphasis being placed on the polluter to pay its costs. 
 
The recent changes in Building Regulations place these responsibilities on the designers of sustainable buildings, and call for them to approach Solar Shading as the first consideration in the provision of energy efficient projects. 
 
 
Legislation 
 
EU Energy Performance of Buildings Directive (EPBD) Part L1 and Part L2 
 
“To promote the improvement of the energy performance of buildings within the community, taking into account outdoor climatic and local conditions, as well as indoor climate requirements and cost” 
 
Energy Performance Certificates (EPC) – required now for any commercial building which is sold, let or built 
Display Energy Certificates (DEC) – required for all public buildings over 1000m2. Certificate must be on display 
 
Examples of legislation that indirectly affects energy use in buildings: 
 
Carbon Reduction Commitment – aimed at major uses of energy this will be a cap and trade scheme – i.e you will be given a limit on emissions and if you produce more you will have to buy carbon credits. A league table of polluters will be published annually 
Energy Services Directive – requires UK to reduce energy consumption by 9% by 2017 and for the UK public sector to take an exemplary role. 
 
Legislation is becoming more onerous and the prospect is it will only get more stringent. The common light bulb, unchanged for over a century, will be withdrawn from sale within the next two years as a result of legislation. 
 
Standards 
 
SAP (Standard Assessment Procedure) – Measurements procedure for showing compliance with Part L for dwellings 
SBEM (Simplified Building Energy Model) – Measurements for showing compliance with Part L for non-domestic dwellings 
BREEAM (Building Research Establishment Environmental Assessment Method) – The BREEAM family of assessment methods and tools are all designed to help construction professionals understand and mitigate the environmental impacts of the developments they design and build. 
 
Solar shading is included in all these models, although not with the emphasis that we believe is warranted. 
 
 
Corporate Social Responsibility 
 
Corporate Responsibility is the management of a company’s impact on society, and the environment, in recognition that the impact of a business goes beyond strict legal, financial and regulatory responsibilities. 
Publicly quoted companies are obliged to include reporting on corporate responsibility in their annual reports, and many have significant details provided on their websites. 
Public and private sector organisations want to be seen acting in a responsible manner, and reducing energy emissions through solar shading could be one way.

DISC 
 
DISC (Dynamic Insulation Strategies and Comparison) is a software tool pioneered and validated by leading scientific members in governmental research, academia and industry. 
 
The members are: Energy and Build Design Department of Architecture and Built Environment at Lund University in Sweden, Somfy, Copaco Screenweavers, Dickson, and Veresol. 
 
Dynamic insulation of facades allows for better control of thermal exchanges, enhancing energy efficiency and sustaining thermal comfort. 
 
The results provided by DISC allow project managers to communicate on an energy savings strategy in an easy and reliable way. Energy savings opportunities are presented clearly and efficiently, thus encouraging multiple comparisons in material choices and automation systems. 
 
DISC will simulate the potential energy savings, dependent on the external climate conditions, building orientation, chosen window, glass configuration and internal heat loads. 
 
The energy saving may depend on the applied control strategy of the shading system
