A most sustainable and economical way to build

Most people involved in the construction of buildings are concerned about the environment and the associated costs with heating, cooling and ventilating a building during its lifecycle. If you are intending to increase the levels of efficiencies on your construction projects(s), or you want to make savings on capital costs, lessen the impact on local and wider environments, or achieve a combination of them all then Green Building Design can really help.

This is a fascinating area of construction that encourages design teams to focus on how a building can improve its thermal performance using passive measures followed by the consideration and selection of suitable energy systems and renewable energy generation.

Sustainable Building-Design is at the centre of the UK’s construction industry mix and is continuing to dominate exemplar building innovation. Developers are demanding to know more and more about how a building’s thermal performance can be improved using passive measures, in particular as Building Regulations carbon reduction targets increase and Planners impose tougher project conditions.

TWC Consulting offers a Sustainable Building-Design service that focuses on the thermal efficiencies of a building’s fabric, the procurement of sustainable materials and the long-term viability of the building’s energy systems.

Passive House & Green Building Design

Passive House, or Green Building Design are broad terms used to describe the construction of highly energy efficient buildings that require minimal input from conventional energy systems to provide heating and cooling. The standard can be used for both domestic and non-domestic buildings [either new-build or existing building retrofit].

The growth of Green Building Design throughout the UK continues to expand each year as the number of registered projects increases. In simple terms, Green Building Design relates to buildings that do not require traditional heating or cooling systems to deliver space heating or hot water. The building specifies leading energy reduction systems such as; ventilation units with heat recovery, very low levels of air leakage, high-end insulating building materials and comprehensive reduction of thermal bridges

One of the key advantages of Passive House is the controllable zoned areas which can be adjusted to suit the thermal comfort levels of the occupants. This level of control helps reduce the demand for energy, which in turn reduces running costs and life cycle maintenance.

There has been some research to confirm the increase in capital costs for a Passive House is approximately 8-10% over a standard building. To highlight a point: Passive House has a target of 15kWh of energy use, per square metre, per annum. Therefore, a 70m2 house with a gas supply could spend as little as £25 on heating each year.

Thermal Retrofit

Thermal retrofit relates to a change from existing unsustainable building to an upgraded sustainable building, and it’s not as difficult as it first may appear. The initial stage of a retrofit is to complete a feasibility study and option appraisal to confirm the range of options available.

Secondly, a specification and programme of works outline details of the upgrade programme. For the majority of buildings the costs of the upgrade will be paid back within a 10-year period, and thereafter the occupants benefit from having a sustainable building and profitable returns from energy savings and available tariffs

The purpose of a retrofit is to make a building less leaky from cracks and openings in the fabric, to increase wall insulation, uplift loft insulation, floor insulation, replace windows and external doors, replace inefficient boilers and install renewable energy systems where feasible. The retrofit can be completed in one visit, or carried out progressively over a period of time i.e. on a room-by-room basis.

TWC Consulting provides a free of charge appraisal on all available options and best to turn around an unsustainable and expensively run building into an efficient and profitable asset.
