Working together to make strict deadlines

The Challenge

When you have responsibility for some of the country’s biggest new build developments, co-ordinating between the various consultants and specialists can get out of hand. And when you add pressing time frames into the mix, the need for a close-knit team of experts is key to making sure things run smoothly.

Redrow’s London team has experienced the benefits first hand of using Energist to cover multiple requirements. We were asked to provide a coordinated Energy, Sustainability and Overheating strategy on their mixed use scheme at Capital Interchange Way; including 420 dwellings, offices and retail spaces. This would be a complex and challenging scheme at the best of times, but this site also came with a short turnaround from design development to submission. The site was also subject to acoustic and air quality constraints which limited the options for avoiding overheating risk in the new homes.

The Solution

The Energist Technical Team worked closely with the acoustic and air quality teams to identify facades where openable windows were restricted. Mechanical cooling was specified in these areas to create a compliant overheating strategy which was delivered to the local planning authority on schedule.

Energist then continued to develop the Overheating Strategy with the help of the rest of the design team. We were able to value engineer the details, so comfort cooling was no longer required in parts of the development without impacting the overheating or energy targets. The Energy Strategy for the scheme was then aligned to the Overheating Strategy; focusing on a Combined Heat and Power (CHP) lead energy centre.

Energist also explored an air source heat pump solution to give the Redrow team a better understanding around the implications of the Greater London Authority’s (GLA) January 2019 Energy Assessment Guidance – which includes the introduction of SAP10 emission factors.

Energist responded at length to queries directly from both the local planning authority and the GLA, which ensured the strategies didn’t need to go through extensive rewrites to take on board additional comments. The scheme contains large areas of commercial and retail space on multiple floors. Energist engaged the design team on the BREEAM Assessment early in the process, assigning responsibility and addressing RIBA Stages 1-3 dependant credits. This ensured any risks associated with BREEAM were reduced early-on. Following this stage, our Technical Team carried on liaising with the rest of the design team to create full design stage BREEAM assessments.

The Result

At all times in the process we coordinated our technical solutions with the rest of the design team before presenting them to the client. This joined up approach helped Redrow to meet the stringent deadlines required to meet the submission deadline.

Our strategies have been approved by both the local planning authority and the GLA, with the site awaiting determination.

Energist’s track record on schemes like this has been shown to be a great asset to reduce the time you need to spend chasing consultants and panicking over pressing deadlines.
