______ Project Overview
This Grade B listed, traditionally built, corner building is currently a Council office building. The building includes a later wing that was rebuilt in 1992.

The proposed conversion of the Kildonan Street Council offices into 43 social housing homes incorporates part demolition, façade retention, part new build, part conversion and some new interventions. It is a mixed-use scheme and incorporates office space retained under council management within the grander spaces of the historic building.

______ Our Scope
Carbon Futures was responsible for Section 6 and Section 7 compliance through our role as Energy Consultant.

The three areas of the building, one area of new build and two areas of retrofit required tailored compliance routes to meet regulations and EPC band B ratings, a client briefing requirement.
We worked closely with Collective Energy to develop the strategy for each of the three parts of the building which were designed to suit the specific construction of that area.

Additional services provided by Carbon Futures included a Statement on Energy (Planning), Approved Certifier of Design (Energy) certification, Thermal Bridging Calculations, and Building Regulation Compliance through the provision of SAP Calculations and provision of Energy Performance Certification.

______ Details
It is proposed that a shared ambient borehole loop is used to individual water-to-water heat pumps within the proposed dwellings to provide space heating and domestic hot water. This Zero Direct Emissions Heating System benefits from being very efficient, whilst still allowing tenants to procure electricity from their own energy provider.

The new-build Police Wing will be steel frame construction with façade retention, and includes the following:

N

Achieves a 42 % carbon reduction abatement achieved through the use of LZCGTs.

N
Low wall, floor and roof U-values reducing Space Heating Demand.
N
Triple glazed windows.
N
MVHR ventilation with a designed air permeability of ≤ 1.0 m³/hm² @ 50Pa.
N
Calculated Psi-values for thermal bridging.
N
An average SAP Rating of 85B and Environmental Impact Rating of 97A.
Aspect Platinum Level 1 (Greenhouse gas emissions) and Aspect Gold Level 2 (Energy for Space Heating) are being met for all but one flat under Section 7 (Sustainability) of the 2024 Building Standards.

The converted North Block is the 1992 existing brick wall construction, and includes the following:

N
Achieves a 60% carbon reduction abatement achieved through the use of LZCGTs.
N
Low wall, floor and roof U-values reducing Space Heating Demand.
N
Triple glazed windows.
N
MVHR ventilation with a designed air permeability of ≤ 5.0 m³/hm² @ 50Pa.
N
Photovoltaic panels with excess electricity exported to the grid.
N
An average SAP Rating of 84B and Environmental Impact Rating of 97A.
Aspect Platinum Level 1 (Greenhouse Gas Emissions) has been met throughout and a mixture Aspect Silver and Bronze Level 2 (Energy for Space Heating) being met under Section 7 (Sustainability) of the 2024 Building Standards.

The converted West Block is of traditional stone wall construction, and includes the following:

N
Achieves a 60% carbon reduction abatement achieved through the use of LZCGTs
N
Moderate wall U-values with low floor U-value to reduce Space Heating Demand.
N
Triple glazed windows.
N
MVHR ventilation with a designed air permeability of ≤ 7.0 m³/hm² @ 50Pa.
N
Photovoltaic panels with excess electricity exported to the grid.
N
An average SAP Rating of 83B and Environmental Impact Rating of 97A.
Aspect Platinum Level 1 (Greenhouse gas emissions) has been met throughout under Section 7 (Sustainability) of the 2024 Building Standards.

By accurately predicting energy consumption and closing the industry-wide performance gap, the project aims to protect residents from fuel poverty. This whole-building approach keeps energy demand low while prioritising occupant comfort and well-being.
