Project Description

Client: Crest Nicholson Regeneration
Location: Bath Riverside
Units: 813
Type: Mixed Use

Project Summary

Bath Western Riverside, is a multi-phased development consisting of residential dwellings and commercial units. Crest Nicholson Regeneration has re-developed a once industrial intensive site into an attractive riverside community.

The entire development’s space heating and hot water demands are served by central plants consisting of Mains Gas CHP, Biomass boilers and Gas back-up boilers.

Bath Western Riverside had site wide targets to provide at least 10% carbon savings from renewables and/or low-zero carbon energy technologies, as well as meeting all the requirements set by the Code for Sustainable Homes and BREEAM.

The Challenge

Each phase consisted of different construction methods, innovative architectural design and were dictated by the applicable version of Building Regulations.

This prompted early engagement with the design team to ensure that the most cost-effective and viable solutions were used to meet the necessary requirements per phase, whilst maintaining a relatively consistent approach towards the development’s overall sustainability strategy

Project Description

Client: Legal & General Homes
Location: Buckler’s Park, Crowthorne, Berkshire
Units: 207
Type: Mixed Use

Project Summary

Buckler’s Park, a 250-acre site in Berkshire, is Legal & General Homes’ first development of sustainable, contemporary-styled houses. The development is built to Part L 2013 with 19% site-wide carbon emissions savings from renewables.

The Challenge

AES Sustainability Consultants are providing Legal & General Homes with an end-to-end service to ensure that energy and sustainability targets are met cost effectively by:

  • Challenging complex planning conditions by working with the planners, providing a cost-effective solution, saving the client £1million by reducing PV requirement using our approach.
  • Developing a value engineered specification, taking the lead from the client on their supply chain decisions, such as the use of aggregate inner leaf blockwork.
  • Assisting with overheating analysis.

We will continue to coordinate and carry out the onsite air-testing and production of EPCs to provide the client with our end-to-end service.

“I have worked with AES over a number of years and they have provided me with great service at all times, their willingness to help at critical stages of the design process and make meeting at short notice with Planning Authorities is also appreciated. For me their work ethic is refreshing and they are always willing to strive to get best value for the developer.”

Greyfriars Quarter

Greyfriars | AES Sustainability Consultants

Project Description

Client: Linden Homes
Project: Greyfriars Quarter
Location: Gloucester
Units: 246
Type: Mixed

Project Summary
The Greyfriars Quarter is a mixed-use site in the heart of Gloucester and includes the Gloscat Campus and Media Site. The aim of the development was to create an attractive city centre residential neighbourhood providing 246 new homes and apartments in a mix of styles alongside commercial shops and community services.

The Challenge

On this development, the requirement was to adhere to the Code for Sustainable Homes Level 3 and BREEAM Excellent as well as achieving an overall 10% reduction in carbon emissions across the entire site.  Combining the standards of the Code for Sustainable Homes and BREEAM added a challenge as commercial standards are not normally applied to residential and vice-versa.

The challenge was to meet the conditions using light weight steel frame (Metsec) and traditional masonry around a part steel frame with concrete plank floors, and electric heating. By liaising closely with everyone in the design team, we were able to produce a value engineered solution that focused on  improving the fabric efficiency of the steel frame through good linear thermal bridging details. The solution reduced the amount of PV required to achieve the site-wide target, while also maximising the credits available for the Code for Sustainable Homes and BREEAM assessments.

Project Description

Client: Linden Homes
Location: Nationwide
Units: NA
Type: Domestic

Project Summary

Galliford Try – a FTSE 250 housebuilding and construction group – wanted to develop a national specification for its Linden Homes Layouts to achieve 2013 Building Regulations compliance whilst being easily adapted in order to meet any additional planning requirements cost effectively without compromise to the buildings layout. AES Sustainability Consultants have helped to develop the specification and apply it to a new range of national house-types for building control approval and costing.

The Challenge

The challenge was to create a ‘fabric first’ solution to allow a uniform specification to be used across all future sites, regardless of the planning conditions or site conditions. For example, the window specification was relaxed to allow for the potential use of timber sash windows, and renewable technologies were not selected due to potential planning constraints.

Galliford Try also consulted AES during the production of the standard architectural details to ensure heat loss through linear thermal bridges was minimised. AES then completed Psi-value calculations for the junctions where any improvement in SAP could be gained against industry calculated and Accredited Construction details. The results of these calculations are to be used for all 2013 Building Regulations sites going forwards and provide a significant SAP benefit over Accredited Construction Details and default values.

Galliford Try will also benefit from a wide variety of potential uplifts should particular sites have energy or CO₂ reduction requirements, which has been achieved by avoiding ‘bolt-on’ or renewable technologies for the base specification.

In addition, AES has designed future provision for additional technologies such as Waste Water Heat Recovery into the Linden Layouts at an early stage, minimising the need for changes to working drawings and heating designs, and ensuring construction costs can be forecast accurately.

AES also provided alternative specification options though further SAP modelling to achieve a DER/TER reduction of 19% in line with Code for Sustainable Homes Level 4 requirements.  The general construction and cavity width was maintained, and improved window specification, small PV systems and flue gas or waste water heat recovery systems were also all used where required to achieve the 19% target.
