Performance
To design for Performance on a building project we really start from first principles, bringing our experience of managing buildings for our clients to the table.
We first establish the objectives and targets for the project (such as Nabers, BREEAM and/or Zero-Carbon). We then assess the following items:

Structured Approach
to Low Energy Design
We will adopt a tried and tested structured approach to designing and proving our low energy design. The steps are outlined below.
Reduce Energy Demand
The process starts with minimizing energy demand at source by measures including the bullet points outlined above. It is important to note that the impact of some of the desired criteria are conflicting and it is important to achieve the best compromise – for example maximising natural daylight will tend to increase solar thermal gains and reduce the ability of natural ventilation to control internal temperatures. We will lead the design team through a thorough process of considered discussion and option appraisal to conclude the optimum balance of energy minimisation.
Analyse Energy Performance
Having reduced energy performance, it is important to understand the real impact of various design solutions and illustrate these clearly to allow a cost-benefit-energy appraisal to be made. We undertake holistic computer modelling in-house using our state-of–the-art IES Facet software suite to consider the effects of various design measures upon temperature, daylight, comfort and energy. These analyses are iteratively applied to reach the best solution for the building.
Consider the Benefit of Renewable Energy Generation
If the challenging target of Zero Carbon is to be realised for Kilmarnock College, maximum benefit must be derived from the application of on-site renewable technology. It is essential that a structured appraisal of the various, genuinely viable renewable technologies is undertaken rather than to “bolt-on” token renewables of high visual impact, but low carbon benefit.
KJ Tait Engineers are market leaders in the practical and proven design and application of on-site renewable energy to education buildings to minimise carbon emissions with considerable benefit in CO2 reduction. Significant examples include a major Biomass heating plant at Queen Margaret University, CHP plant at Cranfield University and several notable Ground Source Heating and Cooling installations.

Deliver Real Benefits and Make Business Sense
Client and user benefits of a low energy and low carbon approach can include savings in energy costs and whole life costs, user comfort, simple easy to manage solutions and marketing benefits in attracting students to a sustainable environment. These benefits must be real rather than perceived, and this will be validated by the achievement of a high EPC rating and an Excellent BREEAM rating. KJ Tait Engineers are Registered BREEAM Consultants and EPC Assessors and will embed a nominated specialist within the team to ensure that the maximum benefits are achieved in terms of energy, cost and accolades – delivering a development that delivers real benefits and makes business sense.
