In its creation of communities, it strives to design developments which attract a broad range of residents.
Sigma has joined the United Nations Global Compact (“UN Global Compact”), which is a voluntary initiative designed to encourage business leaders to implement universal sustainability principles and in particular the UN Global Compact’s Ten Principles. These are derived from the Universal Declaration of Human Rights, the International Labour Organisation’s Declaration on Fundamental Principles and Rights at Work, the Rio Declaration on Environment and Development, and the United Nationals Convention Against Corruption.
Sigma is therefore committed to aligning its strategies and operations with the Ten Principles and to taking action to advance broader societal goals. Most specifically, Sigma aims to create residential environments that promote societal and individual well-being through the provision of:
We build homes which are suitable for a wide range of tenants, levels of affordability and life-stages, offering families and individuals the opportunity to move to larger or smaller homes dependent on their needs. In this way, Sigma’s developments support a diverse demographic profile and help to create sustainable neighbourhoods.
The development process however is under the direct responsibility of Sigma’s house building partners. As part of Sigma’s due diligence process when relationships are established, we undertake a thorough examination of house building partner policies regarding environmental practices. We require delivery partners to be able to demonstrate policies on the management and origination of their supply chain, usage of resources and their approach to biodiversity. Our two key delivery partners, Countryside Properties and Vistry are both classed as being a ‘Low Risk’ by Sustainalytics in their overall approach to Environmental, Social and Governance and are both rated in the top 10 out of 76 of their peer group for their approach.
Homes are constructed to relevant building regulations and have a minimum energy performance rating of ‘B’ and feature energy efficient LED lighting or low energy bulbs, whole house ventilation systems and efficient gas central heating systems. Innovation is important and Sigma works with housebuilding partners to improve the performance and future proofing of the homes through regular specification reviews.
The most significant change to housing delivery over the year has been the increasing use of Countryside Properties’ new sectional-building technology. This has reduced waste, increased on-site efficiencies and decreased build period. Additionally the system allows for increased control of cost and availability of raw materials, improved quality control, lower transportation usage (and thereby reduced vehicular emissions), and a reduction in Health and Safety risk, due to the controlled internal production environment.
In its use of materials, the system is accredited to PEFC ST 2002:2013, which requires the demonstration of the chain of custody of forest-based products, ensuring the use of sustainable sources. The system recycles 80% of timber waste and 80% of plasterboard waste, which is reused for new plasterboard (the paper lining being used for animal bedding). Plastic wrapping is baled after use and recycled to produce damp proof courses and membranes.
Employees at the factory are drawn from the local workforce and an apprenticeship scheme has been established, which currently employs nine apprentices from Wigan College, who are studying for NVQ’s.
The alignment and synergies between the new sectional-building technology and the Sigma’s values is close, and it is intended that the technology’s usage is increased.
