Energy and Carbon

Passive and Low Energy Design

A combined analysis of climate, site conditions and building’s key parameters allows us to maximize energy efficiency by optimizing orientation, building form, material selection and thermal mass, daylighting and natural ventilation, between many other aspects. An early involvement from our specialist team is recommended, so opportunities to incorporate these measures remain open. 

Low and Zero Carbon Technologies Feasibility Studies

We offer assessment of energy demands against available renewable and low carbon technologies such as Combined Heat and Power (CHP), Photovoltaic Panels, Solar Hot Water Systems and Ground Source Heat Pumps to name just a few. The available technologies are tested against the individuality of each site to ensure the optimum solutions are identified in every case. Initial budget costs can be prepared to provide whole life cost analysis to estimate the payback period of each proposal. 

Planning Energy Statements

We can prepare Energy planning statements detailing the baseline energy and carbon dioxide emissions associated with the project and the savings needed to comply with the applicable planning requirements. 

Working closely with the design teams a strategy will be set. This would normally look to fabric optimization first, then to efficient mechanical and electrical systems. Once opportunities to improve the building design have been incorporated, district heating networks and local renewable options will be considered. 

Energy Reviews and Audits

Our team can review the operational performance of an existing building by identifying current energy usage through survey of the main building services plant, review of utilities bills and interrogation of building management software. The building can then be measured against existing benchmark data to enable realistic targets and strategies to be implemented.

TB+A offer various levels of energy audits, from simple walk around and desktop exercises to very detailed analysis of the energy aspects of all building systems. 

Operational Energy Optimization

TB+A aim to reduce the operational energy an associated carbon emission since design stage.  It is recognized by the industry that compliance calculations do not provide a realistic prediction of energy consumption and carbon emissions (i.e. Performance Gap).

We combine the use of dynamic thermal modelling tools with the relevant industry guidance (e.g. CIBSE TM 54) in order to evaluate operational energy since early stages so informed design decisions are enabled. 

TB+A also undertake this analysis in running buildings, this includes detailed energy audits combined with enhanced simulation models. With this approach, any potential improvement can be accurately evaluated in terms of energy and carbon saving potential, cost and payback.
